An introduction to nanoplasmonics and plasmonic resonance in C60 fullerens using a quantum

hydrodynamic model

F. Tanjia, J. Hurst, P.-A. Hervieux, and G. Manfredi

Institut de Physique et Chimie des Matériaux de Strasbourg (IPCMS), CNRS and Université de Strasbourg, BP 43,

F-67034 Strasbourg Cedex 2, France

Recent years have witnessed a remarkable surge in interest for the electronic properties of new materials,

particularly when excited by electromagnetic radiation. This is a very vast domain of research that

encompasses all sorts of nano-objects, new materials like graphene, as well as metamaterials whose

structure can be engineered so as to display some particular optical properties. We particularly focus our

attention on metallic nano-objects and the composite metamaterials that can be constructed out of them,

such as networks of interacting nanoparticles. Standard methods to study the electron response – such as

the time-dependent density functional theory (TDDFT) or Hartree-Fock (HF) equations – are

computationally very costly in terms of run time and memory storage. On the other hand, recent

approaches rely on much simpler methods based on improvements of the classical Mie theory.

In this particular workƗ, we are intended in the development and implementation of a set of quantum

hydrodynamic (QHD) models to investigate many open problems in the emerging field of

nanoplasmonics. Such models are sufficiently simple to be run on standard computers (desktop PC or

small university cluster), but contain enough physics to study the electron response beyond the Mie model

– in particular nonlinear, nonlocal, and quantum effects. The combination of flexibility and accuracy of

QHD models makes them an ideal tool to investigate many open problems in the emerging field of

nanoplasmonics. We have studied so far the breathing mode of C60 fullerenes by implementing QHD

model by means of a variational approach. The ground state and the linear response frequency of the

system is studied. The electrons oscillate with a frequency of the order of plasma oscillations (volume

plasmon). The result is verified by QHD numerical codes as well as density functional theory (DFT)

calculations. A further investigation to study the dipole mode in the nonlinear regime is under way. In the

near future nonlinear, nonlocal, and quantum effects of several configurations of nano-objects (i.e.,

dimers and trimers of metallic nanoparticles, nanoshells, metal-dielectric multilayers, nanoparticles in the

vicinity of a thin metal film, and arrays of nanoparticles interacting via the dipole force) will be studied.

Disorder induced low-energy quasiparticle states in hole doped cuprates: relevance to magnetic

effect and Tc degradation

S.H. Naqib

Department of Physics, University of Rajshahi, Rajshahi 6205, Bangladesh

Substitution of isovalent and non-magnetic Zn in the CuO2 plane strongly perturbs the electronic structure

and magnetic behavior of strongly electron correlated hole doped cuprate high-Tc superconductors. The

physics behind the anomalous enhancement of uniform magnetic susceptibility, χ, in Zn substituted

cuprates is unclear till date. The magnetic behavior has been described mainly in terms of two contrasting

scenarios. i) Independent localized moments appearing in the vicinity of Zn arising because of the strong

electronic/magnetic correlations present in the host compound and ii) transfer of quasiparticle spectral

2

weight and creation of weakly localized low energy states linked to each Zn atom in place of an in-plane

Cu. For this second scenario, one would expect a direct relation between Zn induced suppression of

superconducting transition temperature, Tc, and the magnitude of the enhanced magnetic susceptibility.

We have explored this possibility by analyzing the χ(T) and Tc(x, y) data of sintered La2-xSrxCu1-yZnyO4

with wide range of hole contents, p (= x), and Zn concentrations (y). Results of this analysis provide us

with a unique framework to explain the Tc degradation and anomalous normal state magnetic

enhancement of disordered cuprates.

Feature of a Silicon Quantum Dot Superlattice for High Efficiency Solar Cell

Mohammad Maksudur Rahman

Institute of Fluid Science, Tohoku University, 2-1-1 Katahira, Sendai, 9808577, Japan

Silicon (Si) quantum dots (QDs) have the potential to dramatically improve solar power technologies and

to intensely improve conventional Si photovoltaic (PV) cells. An electron inside a QD cannot move freely

in all directions, so it behaves like an atom, which provides the opportunity to control the energy carrier

states. With such QDs spaced sufficiently close together forming a quasi–crystal structure, overlap of the

wave functions of quantum-confined carriers in adjacent dots enables the formation of a real QD super

lattice (QDSL) with the confined states smearing out to form a miniband. However, Si-QD-based solar

cells fabricated using the conventional bottom-up process exhibit limited performance due to limited

quantum confinement and low density of the QDs. This limitation has been overcome by the fabricating a

sub-10-nm Si nano disk (ND) structure as a QDSL using an innovative technology combining

biotemplates and neutral beam etching (NBE) processes. The QDSL consists of a stack of four 4-nm-thick

Si-NDs and a 2-nm interlayer of SiC being alternatively arranged into a periodic array inside nanopillar

structures with a density of 1.4 × 1012 cm-2 and just short distance of 10 nm as shown in scanning

electron microscope (SEM) and transmission electron microscope images of Fig. 1 (a) and (b). The QDSL

was then sandwiched in between a pn junction solar cell diode where QDSL acted as an intermediate (i)

layer as shown in the SEM image of Fig. 1 (c). The role of the QDSL in miniband formation [1- 3] and its

impact on improving the PV performance of a Si solar cell was investigated with respect to a Si/silicon

carbide (SiC) multi-quantum well (QW) solar cell in a p/i/n+ structure. The effect of vertical wave-

function coupling to form a miniband in the QDSL was perceived based on the solar-cell performance,

showing a dramatic PV response in generating a high photocurrent density Jsc of 29.24 mA/cm2, open

circuit voltage Voc of 0.51 V, fill factor FF of 0.74, and efficiency of 11.07% with respect to QW solar

cell with Jsc of 25.27 mA/cm2, Voc of 0.49 V, FF of 0.69, and of 8.61% as shown in Fig. 1 (d). A wide

range of photo-carrier transports by the QD arrays in the QDSL solar cell is possible in the internal

quantum efficiency (IQE) spectra with respect to the IQE of QW solar cell. Moreover, a distinguished

carrier transport characteristics of the QDSL could be extracted from an extended study with the

passivation film of atomic layer deposition (ALD) aluminum oxide (Al2O3) with respect to conventional

sputtered grown a-SiC film in a p++/i/n+ junction solar cell [4-5]. Here high-doped-density p++ Si

substrate acted as a hole conductor instead of generating photo-carriers so that we could observe the PV

properties of the i-layer only.

3

The largest photocurrent density of 4.75mA/cm2 was generated from the QDSL with the ALD-Al2O3

passivated surface and is suitable for high-efficiency QD solar cells compared with a-SiC-passivated

(0.04 mA/cm2) QDSL surfaces. The enhanced PV performance of the QD solar cells was clarified in

terms of simulating the absorption contributions for all possible transitions in the nanostructure with

these different passivation films.

Jamology - from mathematical modeling toward practical use on traffic flow

Akiyasu Tomoeda

Japan

Various kinds of the collective motion of Self-Driven Particles (SDP), such as vehicles and

pedestrians, have attracted a great deal of attention in a wide range of fields during the last few

decades. Most of these complex systems are interesting not only from the point of view of natural

sciences for fundamental understanding of how nature works but also from the points of view of

applied sciences and engineering for the potential practical use of the results of the investigations.

Especially, interdisciplinary research for the dynamics of jamming phenomena in SDP systems, so-

called ”Jamology”, has progressed by developing sophisticated mathematical models considered as a

system of interacting particles driven far from equilibrium with a central focus on the jamming

phenomena in traffic flow. In this talk, starting from the definition of the ”jamming state” in 1-d

transportation system, several mathematical models and their relations are shown in the case of traffic

flow. Then, the mechanism for forming the spontaneous traffic jam on expressway will be explained.

Moreover, I would like to introduce the real demonstration experiment for absorbing traffic jams.

Department of Physics, Jahangirnagar University, Savar, Dhaka-1342

There has been always a persistent search for creating cheaper and efficient energy storage devices.

After its discovery of Li+ ion storage device has become the most preferred choice due to its high

energy density. However, developing anode materials for more efficient lithium ion storage devices is

still very challenging and lots of effort has been made recently to design efficient anode materials for

such devices. Realizing the need for developing novel ion storage devices, present study aims to

investigate hexagonal boron (B6) cluster‟s ability to store Lin+ (n=1,2) ions. Different geometrical,

optical and electronic properties of lithium doped hexagonal boron clusters are studied. Theoretical

investigations are done by using density functional theory (DFT). Our results show that energy band

gap and chemical stability of the hexagonal B6 nanocluster increases when lithium atom(s) are doped

in it. Adsorption energies of the doped cluster indicate that the lithium atoms are adsorbed very well

in the nanocluster. The specific capacities of the LiB6 and Li2B6 are found to be 413 mAh/g and 826

mAh/g respectively.

Development of Method for Rapid Quantification of Glucose, Fructose and Sucrose in Mango

Juice by Chemometric Techniques in De-noised FTIR Spectroscopic Data

Uddin M. N., Majumder A. K., Ahamed S., Saha B. K., and Motalab M.

The present study is aimed to develop a chemometrics assisted method for predicting simple sugars

(glucose, fructose and sucrose) in mango juice by using the best calibration technique among

5

Artificial Neural Network (ANN), Principal Component Regression (PCR) and Partial Least Squares

Regression (PLSR) in de-noised data from Fourier Transformed Infrared (FTIR) spectrophotometer.

Sixty four mixture solutions of eight different concentrations of sugars and fifteen commercial mango

juices have been run in FTIR, and spectral data are used for development, validation and test of

models. Standard Normal Variate (SNV), Savitzky-Golay (S-G) filtering and Multiplicative Scatter

Correction (MSC) have been used for de-noising spectral data before calibration. Among the

alternatives, the best prediction performance is noticed by ANN in spectral range 1500-952 cm-1 and

S-G filtering (R2≈0.99). Prediction of simple sugars concentration by ANN with FTIR spectroscopic

data after de-noised with S-G filtering is a cost-effective and easy method for quantification of sugars

in commercial mango juice.

Bangladesh is an agricultural country. But the contribution of agricultural sector in GDP in

Bangladesh is decreasing last several years. Flood is one of the main important factors in Bangladesh

that affects agricultural production each and every year. In this paper, we want to develop a stochastic

linear programming model for optimizing the agricultural production considering flood as a stochastic

variable. Other constraints are agricultural inputs such as land, labour, fertilizer, loan, seeds, pesticide,

and irrigation that influence agricultural production.

Treatment of the labile complex, [Os3(CO)10(NCMe)2], with 2-mercaptobenzoxazole at ambient

temperature and at 66oC resulted in the isolation of new isomeric tri-osmium clusters, [Os3(CO)10(µ-

H)(µ-SCNOC6H4)] (1A)and (1B) respectively as yellow crystals in high yield. On the other hand,

heating 1A at 66oC gave 1B exclusively. Compounds1A and 1B were formed by the displacement of

MeCN ligand from [Os3(CO)10(NCMe)2] followed by a facile S-H bond activation in 2-

mercaptobenzoxazole ligand. Conversion of 1A to 1B involved a thermal ring expansion process

together with hydride flipping. The complexes, 1A and 1B, were characterized by elemental analyses,

IR and 1H NMR spectroscopic method. Structure of the complexes was unambiguously determined by

single crystal X-ray diffraction method.

The nonlinear propagation of ion-acoustic waves (in which the inertia (restoring force) ismainly

provided by the heavy negative ions) in a three-dimensional cylindrical, collisionless,and

unmagnetized plasma whose constituents are ions and nonthermal electrons has been investigated. In

Transparent conducting oxide (TCO) is one of the most important materials of modern electronic

devices. Tin (IV) oxide (SnO¬2) has some unique properties such as intrinsically n-type

semiconductor, wide bandgap, transparent in visible region, high carrier concentration etc., which

makes it worthy to use for TCO layer. Undoped tin oxide (SnO2) thin films with varying thicknesses

were prepared by spray pyrolysis technique. Alcoholic (methanol) solution of Stannic chloride

pentahydrate (SnCl4.5H2O) was used as the precursor. The thickness of the films was varied by

repeating the spraying process several times. The prepared films were characterized by x-ray

diffractometer (XRD), ultra-violet visible spectroscopy (UV-vis), four-probe measurement and Hall

Effect measurement. The XRD pattern represents the tetragonal rutile structure of the prepared

sample. The minimum grain size was 14.12nm for (110) plane and the maximum grain size was

32.61nm for (310) plane. The average crystal grain size of the prepared films was 24 nm. The

electrical resistivity of the prepared films decreases with increasing the thickness and the lowest

resistivity was found to be 0.2218 ohm-cm. The carrier concentration decreases with increasing the

thickness of the films. The transmittance was more in the visible region than UV region. The optical

band-gaps were almost same for all the prepared films and it was about 3.6 eV. All of the results

indicate that the developed tin oxide thin film might be promising for use in optoelectronic application

as transparent conducting oxide (TCO) layer.

The coastal environment represents the transition area between the land and the sea. Due to the

interaction between the continental, marine and the atmospheric processes, this area is inherently

dynamic and is subject to continuous transformations. The changing positions of the coastline are of

elemental importance to coastal zone management. Considering the rate of global accelerated sea

level rise and population density in coastal areas, changing coastline has become more than a topic of

scientific curiosity and has profound impact on the coastal communities. Quantitative information

about coastline position is fundamental for the calculating erosion rates, placing setback lines,

redefining jurisdictional boundaries and identifying most hazard prone areas. Remote sensing

technique effectively allows detection and measurements of the coastline changes. However the main

8

challenge of coastal remote sensing is centered on the extraction of coastline from satellite images. In

this study, a semi-automated method has been used to extract the coastline from the coastal areas of

Bangladesh using the infra-red bands of satellite imagery. To understand the influence of image

resolution, coastline extracted from both medium and high resolution images are compared.

Furthermore, to assess the coastal dynamics the nature of coastline movement are also calculated. The

comparisons indicate that both the deltaic and non-deltaic coasts of Bangladesh are highly dynamic

and considering the magnitude of erosion, immediate interventions area necessary in some erosion

hotspots.

The present research deals with the FEG-EPMA mapping and Fe-Ti oxide minerals chemistry of

Brahmaputra river sediments in Bangladesh. Major heavy minerals in the sediments consist of garnet

(8.5-21.3%), kyanite (5.35-11.9%), monazite (2.3-5.3%), sillimanite (1.8-4.7%), zircon (3.6-9.1%)

and considerable amount of opaques mainly Fe-Ti oxide minerals (23.1-35.4%). The detrital Fe-Ti

oxide minerals carry significant clues to the parent rocks or sources. In these contexts, detrital

opaques (Fe-Ti oxides) have been analyzed with an electron probe micro-analyzer (EPMA). These

opaques (Fe-Ti oxide) display six types of textural patterns, dominantly seriate with granular,

emulsion, acicular, sandwich structures and trellis type of textural patterns. These textural patterns

belong to five intergrowths of Fe-Ti oxide minerals such as (1) Ilmenite-hematite, (2) Magnetite-

ilmenite, (3) Hematite-Rutile, (4) Ilmenite-Hematite-Rutile and (5) Ilmenite-Rutile, where ilmenite-

hematite intergrowth is common. Alteration is seen in both exsolved and unexsolvedilmenites.

Textural patterns and mineral chemistry of the studied ilmenite minerals provide evidences of low

temperature magmatic inheritance, later modified by diffusional processes. The estimated temperature

and oxygen fugacity from the magnetite-ilmeniteexsolution ranges from 547.6°C to 558.2°C and 10-

21.4 to 10-21.7 respectively. The data are also consistent with hematite-ilmenite temperature (between

537°C and 540°C) and oxygen fugacity (10-21.7to 10-21.9) measurements. These temperatures and

oxygen fugacities specify Fe-Ti oxide assemblages equilibrated in a T-fo2 field very near to the FMQ

buffer curve suggesting a crustal source, which modified significantly by metamorphic processes.

The crystalline basement rock of drillhole GDH-62 from Dighipara, Dinajpur District of northwest

Bangladesh is encountered between the depths of 1633 to 1721 feet. The crystalline basement rocks

from Dighipara comprises dominantly felsic rocks with a considerable portion of mafic hornblendite

dykes. Felsic rocks are comprised of granodiorite, tonalite, and diorite, which were dissected by ~24

feet thick hornblendite dykes nearly at the bottom of the drillcore.

The felsic rocks (granodiorite, tonalite, and diorite) exhibit leucocratic to mesocratic, hypidiomorphic,

inequigranular, fine to medium grained interlocking texture constituting the primarily variable amount

of plagioclase (33-50%), quartz (12-27%), biotite (6-28%), and K-feldspar (6-12%). Chlorite,

muscovite, epidote, zircon, hematite, and opaque minerals are the main accessories. The amount of

quartz, plagioclase and K-feldspar decreases and biotite increase from granodiorite, tonalite to diorite.

Whereas, hornblendite shows mesocratic to melanocratic, hypidiomorphic, inequigranular, fine to

medium grained interlocking texture. It is mostly comprised of hornblende (67-73%) with biotite,

plagioclase, calcite, chlorite, hematite and opaque minerals. The boundary between hornblendite and

overlying diorite reveals that a high-level late emplacement of mafic magma. The felsic rocks show a

narrow range variation in oxide contents with high contents of SiO2 (71.66-77.18%), Al2O3 (12.36-

15.03%), and Fe2O3t (2.75-4.37%), moderate contents of K2O (1.28-5.4%), and MgO (0.4-1.54%),

and low contents of Na2O (0.31-0.83%). Moderate to close scatter trend of SiO2 versus major and

trace elements Harker variation diagram suggests the felsic rocks derived from a low fractionated

single source and ansyn-collisional and volcanic arc granitoid setting in an ocean-continental

subduction zone.

Orogenic fold belt with various distinctive geometric folded structures is developed along the

collisional plate boundaries due to interaction of tectonic forces and rocks, and generally occur at all

scales from thin section to mountain ranges. Visualization and structural analysis of the fold

geometric features is important not only in deciphering the deformation characteristics, but also to

evaluate the spatial tectonic deformation intensity as well as the related processes of fold belt

development. In this regard, bedding attitude data of six folded structures of the Chittagong Tripura

Fold Belt (CTFB) have been analyzed using Excel, Google Earth, and Stereonet. Spatially referenced

attitude data acquired digitally are compiled in Excel spreadsheet and converted into Keyhole Markup

Language (KML) file using Stereonet 9.5. This KML file is then imported in Google Earth for

visualization of the structure in 3D. In addition, stereographic analysis of the attitude data is processed

and analyzed for the quantitative interpretation of the fold geometric features. Analysis revealed

distinct characteristics of the folded structures in the different part of the CTFB and reflect the

10

tectonic deformation intensity of the outer accretionary wedge within the Indo-Burmese collisional

plate margin. Overall, the outcomes not only enhanced the understanding of the geometric feature and

tectonic deformation intensity of the CTFB, but will also provide valuable insight on the folded

structures of the other young orogenic belt in the similar collisional settings.

The Barapukuria coal basin lies within the basement in northwest Bangladesh. The basin is bounded

by two major faults, N-S trending eastern boundary fault (EBF) and NNE-SSW trending intrabasinal

fault, and an NNW-SSE trending minor fault. The study aims to reveal the character of the basement

hosting the coal with an integrated study of petrography and whole-rock geochemistry for the first

time. The basement in Barapukuria is overlain apart from coal by Permian and Tertiary siliciclastic

rocks. The samples for the current work were collected from the drill holes GDH-38, 39, 40, 42 and

43 encountered at the depths of 513.5 m, 288 m, 655.6 m, 351.3 m, and 437.8 m respectively.

Integrated petrographic and geochemical study classified the Barapukuria basement as tonalite,

granodiorite, granite along with minor granodiorite gneiss, and a hornblendite dyke. The felsic

plutonic rocks are leucocratic to mesocratic and display hypidiomorphic texture, and are composed

mainly of quartz, plagioclase, K-feldspar, biotite, and amphibole. Minor phases are chlorite, calcite,

zircon, epidoteopaques. The granodiorite gneiss shows same mineralogy as granodiorite, with a

distinct fabric developed by preferred orientation of biotite and amphibole. The hornblendite is

hypermelanic, hypidiomorphic and show interlocking texture. The dyke comprises hornblende and

plagioclase with subordinate calcite and clay minerals. Some of the samples from drillcore GDH-38,

40, and 42 shows angular grain, fractured, perforated and pseudo-brecciated nature which are

attributed to the deformation induced by faults in and around the Barapukuria basin. Geochemical

study reveals that, the felsic rocks vary in SiO2 from 57.30 – 71.98%, MgO from 0.78-4.11%, CaO

from 0.61-5.36%, Na2O from 0.27-3.70%, K2O from 1.10-5.06%. The TiO2, Al2O3, Fe2O3, P2O5,

MnO vary within a narrow range of 0.47-1.04%, 16.05-17.32%, 6.06-8.58%, 0.14-0.71%, 0.08-0.19%

respectively. These rocks show a high content of Ba and Sr averaging 1010 and 481 ppm respectively.

The Co, Ni, Cr, contents are low averaging 16, 19, and 31ppm respectively. The major element

Harker variation plot suggests a poor to moderate fractional crystallization in the felsic samples in the

Barapukuria basement. From the AFM plot, most of the felsic samples fall in the calc-alkaline field.

The P2O5 vs. SiO2, Rb/Zr vs. SiO2 and Zr vs. SiO2 plots of the felsic rocks show a typical I-type

trend. Primitive Mantle-normalize incompatible trace element patterns show negative Nb and Ti

anomalies suggesting a subduction zone signature. The tectonic discrimination diagrams of the

studied felsic samples falls within the volcanic arc+syn-collisionalgranitoid field. The source melt for

the felsic rocks of the Barapukuria basement may have generated in an ocean-continent subduction

zone. The primary melt infiltrated into the crust caused further melting there causing low to moderate

degree of fractionation. The hornblendite dyke is interpreted to have originated from a metasomatized

sub-arc mantle wedge and was emplaced later along the fissure and weak zones within the felsic

association.

11

Petrography and geochemical characteristics of the felsic rocks of the Barapukuria basement are

compared with the nearby (~ 14 km west) much-studied Maddhaparagranitoid, which has a U-Pb age

of ~ 1.7 Ga. In both areas, the basement constitutes tonalite, diorite, granite/monzogranite and display

a calc-alkaline, metaluminous I-type character. Considering the proximity between Barapukuria and

Maddhapara, the two areas appeared to have formed in the course of a same magmatic evolution and

from a single source. The halfgraben nature of the Barapukuria basin suggests that it has undergone

post-Gondwana rifting after the formation of the basement, while Maddhapara formed the

corresponding horst and remained unaffected by the deformation.

While both the coal basins of eastern India (EI) and Barapukuria were formed as the result of post-

Gondwana rifting, however, the petrography, origin, and ages are quite different in the coal basin

basement of EI and Barapukuria. The basement rocks of Barapukuria are predominantly made of

granite, granodiorite, tonalite, and hornblendite whereas the basements of EI coal basins are mainly

composed of different types of metamorphic rocks. The basement rocks from the eastern Indian coal

basins show both deformation and metamorphism where the Barapukuria coal basin basement shows

weak to moderate deformation but almost no metamorphism.

Offshore Bangladesh

Md. Upal Shahriar, Delwar Hossain, and Md. Sakawat Hossain

Department of Geological Sciences, Jahangirnagar University, Dhaka-1342


The present integrated reservoir characterization has included the analysis of well logs of Sangu-1 and

Sangu-5 wells and seven 2D seismic lines of the Sangu Gas Field. This field is situated in the Hatia

Trough of the Bengal Basin. Techlog Wellbore Software Platform has been used to analyze the well

log data, whereas Petrel (Shared Earth-Critical Insight) Software Platform was used for seismic data

interpretation. Based on the analysis of Sangu-1 and Sangu-5 well logs and seismic to well tie, seven

reservoirs have been identified as potential hydrocarbon bearing zones at different depth levels in the

two wells and the seismic sections. Lithology of the area is shale, silty shale, sandy shale and

sandstone dominated. The average total porosity of the reservoirs ranges from 13.0% to 25.1%. The

average effective porosity ranges from 7.0 to 25.1%, but in most cases below 13%. The permeability

is very low, mostly below 20mD, except for T2 reservoir where it is 51mD. The average gas

saturation of the reservoirs is between 24.1% and 79.6%. Permeability is most sensitive to water

saturation and porosity where it is negatively affected by water saturation and positively affected by

porosity. Permeability and effective porosity have a linear relationship with the reservoir rocks in

52.7-91.6% cases. The structure is delineated to be a doubly plunging asymmetrical open fold

anticline with a NNW-SSE trend. The identified lithostratigraphic and seismo-stratigraphic features

have a similarity with those lithostrtigraphic and seismo-stratigraphic features of Surma Basin of the

Bengal Foredeep. The total reserve of the gas field is estimated to be 950.89 BCF of which 760.71

BCF is recoverable. Before being shut down in October 2013, about 487 BCF gas was produced from

the field.

Characterization of pores in the lower Cambrian organic rich shales from the mid-upper

Yangtze Block, South China

Sciences, Beijing 100029, China

The organic-rich sediments were widely deposited over the previous carbonate platform as well as

deep basin of the Yangtze Block during Early Cambrian. In the mid-upper Yangtze region, they

comprise the Niutitang, Jiumenchong and lower Bianmachong formations which are dominated by

black shales, except the middle one which is characterized by interbedding of shale and limestone.

The organic richness of these sediments offers a potential shale gas target. Therefore, the present

research work sets out a preliminary investigation on pore characteristics of the Niutitang,

Jiumenchong and Bianmachong formations in two sections (Bahuang outcrop and Daotuo ZK102 drill

core) from northeast Guizhou and one section (Longbizui outcrop) in northwest Hunan, South China.

This study is based on field observations, SEM study and geochemical analyses. Moreover, image

analyses by JMicroVision software were performed to understand the pore system of these rocks.

The study shows that pores in shales of these formations are dominantly nanometer in size, and most

nanopores are associated with organic matter particles (i.e., OM pores). But the pores related to

mineral grains such as interparticle and intraparticle pores are also common. However, the organic

matters in these shales are highly overmature (all vitrinite reflectance values > 2%), which suggest

that hydrocarbons have already been expelled from these organic matters. Therefore, numerous

nanopores are found within remnant OMs, although there is no systematic increase in the size or

number of organic pores with increasing thermal maturity.

The SEM porosities of shales range from 0.21 to 12.40% and the SEM images support the critical

importance of organic matter content on total porosities. The porosities related to organic matter show

excellent, positive correlation with TOC contents. However, the porosity unrelated to organic matter

such as inter- and intraparticle porosities are also appeared to have important contribution in total

porosities, especially for outcrop shale samples in which gaseous petroleum might have been escaped

away. So the petroleum storage potentiality in the subsurface organic-rich shales largely associated in

pores within organic matters.

The talk will focus on the global energy consumption, growth rates over years and its transition

towards cleaner energy sources. Different forms of renewable energy and the energy mix are playing

significant role in shifting towards cleaner, lower carbon fuels, driven by environmental needs and

technological advances. In recent years, per capita energy consumption of Bangladesh has increased

congruently with the economic development. Bangladesh Government has now undertaken a fuel mix

strategy and gradually exploring other alternatives to replace present gas-dependent energy system.

Governments‟ 2030 and 2040 forward plan shows that alternate fuels such as coal, nuclear energy,

import-based gas/LNG will be dominant source of energy.

The untapped chemistry of saccharin (sacH) and thiosaccharin (s-sacH) with M3(CO)10L2

carbonyls (M = Os, Ru, L = dppm, MeCN)-synthesis, structure and reactivity

Shariff E. Kabir

Department of Chemistry, Jahangirnagar University, Savar, Dhaka 1342, Bangladesh

Trimetallic Osmium and Ruthenium dodecacarbonyls [M3CO)12] and its derivatized related

complexes [M3(CO)10(MeCN)2] and [M3(CO)10(µ-dppm)] (M = Os, Ru) had been extensively used as

precursors towards a variety of low-valent osmium and ruthenium trimetallic and in some cases

polymetallic cluster complexes. The diversity lies within the triangular structural rigidity of the

complex. Many of these clusters have found successful usage for homogeneous catalyst. When

reacted with potential donor ligands, such clusters can undergo CO loss, M-M bond cleavage, or even

ligand reorganization, resulting in Polynuclear clusters varying in nuclearities and ligand coordination

mode. Saccharin (sac-H) has been widely used as artificial sweetener. This organic molecule along

with its –thio congener thiosaccharin (S-sacH) contain donor hetero atoms (O, S and N) which make

them potential donor ligands. Unfortunately the related chemistry of sac-H has long been neglected

and less explored. The chemistry between sac-H and S-sacH with trimetallic carbonyls led us to

prepare a range of attractive trinuclear cluster complexes. The synthesis of cluster complexes from the

reactions of [M3(CO)10(MeCN)2] and [M3(CO)10(µ-dppm)] with sac-H and S-sacH ligands will be

discussed. The cluster complexes were characterized using IR, 1H NMR, 31P NMR and x-ray

crystallography.

Mathematics as a Foundation of Research in Various Disciplines

Mohammad Abdul Hoque

Department of Management, School of Business and Economics, North South University, Dhaka, Bangladesh

Mathematics works as a foundation in various disciplines of research. Mathematics plays a vital role

in minimizing cost or time or distance, and maximizing profit or any kind of benefit, with or without

constraints. Various types of mathematical techniques are used in this optimization. When solution to

a problem is either unavailable or available beyond the time limit, mathematics helps to develop a step

by step technique known as the heuristic technique, to reach an expected feasible solution to that type

of problem. Artificial Intelligence, Genetic Algorithm, Neural Network and Simulated Annealing are

such types of techniques. Computer programs are developed following algorithms. The bases of these

algorithms are mathematical logics. Computational time of a computer program in finding a solution

to a problem is generally calculated by the number of operations used to reach to that particular

solution. This number of operations is expressed by a mathematical function. The growth of a

function is used to see whether this computational time increases enormously (NP-hard). Matrix

games are used in carrying out research in a competitive situation for continual improvement of the

overall situation. Mathematics helps to develop various kinds of strategies to make optimal decisions

in these games. Traditionally, economics has been utilizing sophisticated applied mathematics in

operations research. For instance, L V Kantorovich, T C Koopmans, John F Nash Jr., a renowned

mathematicians received the Nobel Prize in economics for their contribution in Operations Research.

Although simulation is sometimes viewed as a “method of last resort”, recent advances in simulation

methodologies, software availability and technical development have made simulation one of the most

widely used and accepted tools in system analysis and operations research. Thus mathematics helps to

make important optimal decisions in various disciplines.

The least square regression analysis is carried out in many areas of research in making appropriate

decisions. This least square regression is the minimization of the sum of the squares of the errors of

the data points for a dependent variable, with respect to the given data points for independent

variable/variables. Thus mathematics had laid down the foundation for the regression analysis.

Various statistical distributions and control charts are used in many research areas, all of which are

developed based on mathematics. The importance of probabilistic methods in almost all areas of

mathematics has been exploding. Using probability theories many basic problems can be modeled by

treating them as discrete or continuous.

Physics and chemistry are the traditional areas for applications of mathematics. Albert Einstein's

general theory of relativity was established following the developed mathematical theories.

Information exchanges between mathematicians and physicists led to substantial progresses in

theoretical physics. Most of the progresses in pure mathematics were impelled by the newly faced

problems in physics. The chemistry department of the Harvard University quoted, “Chemistry has

benefited more and more from mathematical developments and concepts”. Notably, Herbert A.

Hauptman, John A. Pople and Walter Kuhn - all three Nobel Laureates in Chemistry, originally

had doctorates in mathematics. Mathematical models have also been emerging in the biological and

medical sciences. Dynamical systems theory in mathematical biology has attracted a lot of attention of

the researchers from many scientific directions.

Finance has to deal with derivatives, stock options, risks and portfolio management. Recently, the

supply chain management has emerged in various areas of management. Synchronization of flow in a

supply chain is essential for optimal management of a system. All these are modeled mathematically

and hence mathematicians are having a real impact on how those businesses are evolving. Much of

science, engineering, technology, business and management has been building on computation and

simulation, for which the mathematical sciences are the natural language. In addition, data-collection

capabilities have been expanding enormously, and the mathematical sciences have been innately

involved in distilling knowledge from all that data. When research in mathematical sciences produces

a new way to compress or analyze data, value financial products, process a signal from a medical

15

device or military system, or solve the equations behind an engineering simulation, the benefit can be

realized quickly. The process of simulation-based science and engineering is inherently very

mathematical, demanding advances in mathematical structures that enable modeling; in algorithm

development; in fundamental questions of computing; and in model validation, uncertainty

quantification, analysis, and optimization. Theoretical physics or theoretical chemistry or theoretical

computer science is indistinguishable from research done by mathematicians, and similar overlaps

occur with theoretical ecology, mathematical biology, bioinformatics and an increasing number of

fields.

It is becoming more widespread as more fields are becoming amenable to mathematical

representations. This explosion of opportunities means that much of twenty-first century research is

going to be built on a mathematical science foundation, and that foundation must continue to evolve

and expand for the benefits of mankind. To cope with this increasing demand, the mathematical

sciences are best conceived as an interdisciplinary field, integrating mathematics, statistics and

computation in the broadest sense, in areas of potential applications. In this study, mathematics as a

foundation of research in various disciplines is explored, the concerned materials are highlighted and

discussed to motivate its anticipated better applications, in order to open up more for other disciplines

and to foster the line of inter-discipline research.

A rigorous theoretical investigation has been performed on dust-acoustic (DA) solitary structures in a

self-gravitating dusty plasma containing inertial dust of opposite polarity, trapped ions, and

Boltzmann electrons. The Burgers equation and its solution are derived using reductive perturbation

method. The basic features (viz., polarity, amplitude, width, and speed) of the DA shock waves (SWs)

are studied analytically as well as numerically. It is observed that the combined effects of self

gravitational field, trapped ions and dust of opposite polarity significantly modify the nature and basic

properties of the DA SWs. The present investigation can be very effective for understanding and

studying the nonlinear characteristics of the DA waves in different space dusty plasmas.

Applications of Artificial Neural Network (ANN) & Support vector machines (SVMs) in

Predicting Stock Market Returns: A case study on Dhaka Stock Exchange

Md. Siddikur Rahman, and H.M. Simon



Share Market is an untidy place for predicting since there are no significant rules to estimate or

predict the price of share in the share market. Many methods like technical analysis, fundamental

analysis, time series analysis and statistical analysis etc. are all used to attempt to predict the price in

the share market but none of these methods are proved as a consistently acceptable prediction tool.

Artificial Neural Network (ANN), a field of Artificial Intelligence (AI), is a popular way to identify

unknown and hidden patterns in data which is suitable for share market prediction. Another machine

16

learning algorithm Support vector machines (SVMs) are promising methods for the prediction of -

financial time series because they use a risk function consisting of the empirical error and a

regularized term which is derived from the structural risk minimization principle. Paper presents first

detailed study on data of Dhaka Stock Exchange (DSE) to predict the stock market volume of Dhaka

Stock Exchange (DSE). In this study, we have applied and compared salient machine learning

algorithms to predict stock exchange volume. The aim of this paper is to provide a review of the

applications of ANN & SVM in stock market prediction in order to determine what can be done in the

future.

Vanadium oxide (V-O) nanoparticles were synthesized in dielectric liquid water and characterized. X-

ray diffraction refinement of the nanoparticles identified the orthorhombic V2O5 phase from water

medium. Pure and fine V2O5 phase was produced from the water medium. X-ray photoelectron

spectroscopy (XPS) identified the spin-orbit V2p peak splitting of 7.4 eV, and the symmetric in nature

of all doublets, which confirmed the formation of V2O5 compounds. The high resolution TEM (HR-

TEM) identified the average size of the nanoparticles derived from water of 5 nm. Field emission

SEM (FE-SEM) identified densely distributed V2O5. The high yield of V2O5 nanoflowers were

identified in water, where every flower consisting of beltlike petal structure with the average flower

size of 10-20 ?m. Energy dispersive X-ray spectroscopy (EDX) illustrated the existence of oxygen

with vanadium in atomic percentage (%) of 75. Moreover, the band gap of as-synthesized V2O5

nanoparticles were found to be 3.35 eV measured by spectroscopy by using Tauc relation.

investigated by the reductive perturbation method, and small-k perturbation expansion technique. The

combined effects of external magnetic field (obliqueness), dust of opposite polarity, and trapped ions,

which are found to significantly modify the basic properties (amplitude and width) of small but finite-

amplitude DA solitary waves (DASWs), are explicitly examined. It is also found that the instability

criterion and the growth rate are significantly modified by the external magnetic field and the

propagation directions of both the nonlinear waves and their perturbation modes. The implications of

our results in space plasmas are briefly discussed.

Md. Shameem Hassan Bhuiyan, Md. Abdul Mannan Chowdhury, and Dewan Abdul Quadir


Pre-monsoon flash floods over northeastern haor region of Bangladesh are studied to develop forecast

system by using Weather Research and Forecasting (WRF) model and Climate Prediction Tools

(CPT). WRF model can provide more precise flash flood early warning in one week advance. Under

this process WRF can provide seven days accumulative rainfall forecast precisely. With the help of

WRF model, hindcast validation applied for the years 2004 and 2010 flash flood events using NCEP

FNL data and flash flood event of 2016 forecasted using Global Forecast System (GFS) model data.

Climate Predictability Tool (CPT), a statistical model used to predict the teleconnection between pre-

monsoon flash flood producing heavy rainfall (Predictant) over Meghalaya basin and different

meteorological parameters (Predictors). Total eight predictors has been used to identify the correlation

with rainfall over Haor basin as predictant. It has been found that two predictors, out of eight have

statistically significant strong correlation with rainfall over selected domain (Barak basin). The

correlation has been found 0.81 with geopotential height of 500 hPa levels and it is used as predictor

and the correlation has also been found 0.75 in case of geopotential height of 200 hPa level. With the

help of this teleconnection, CPT used to develop a Long Range Forecast (LRF) of flash flood early

warning system in one month ahead over Northeastern Haor region of Bangladesh.

Positron-acoustic (PA) solitary waves (SWs) in plasmas consisting of immobile positive ions, mobile

cold positrons, and nonextensive q-distributed hot positrons and electrons are studied. By employing

the reductive perturbation technique the Korteweg–de Vries (K-dV) equation is derived. The phase

speed, amplitude, width, and polarity of the PA SWs are examined. It is obtained that the electron and

positron nonextensivity effects play a notable role on the fundamental characteristics of PA SWs. The

relative strength between nonlinearity and dispersion is also observed. We hope that our present

18

observation will be helpful for understanding various space as well as laboratory plasma

environments.

Temperature Superthermal Electrons

Md Sahadat Alam, L. Nahar, and A. A. Mamun



A theoretical investigation is made on the dust-ion-acoustic (DIA) solitary and shock waves in an

unmagnetized dusty plasma system consisting of inertial ions, superthermal electrons (following

kappa distribution) with two distinct temperatures, and arbitrarily charged static dust grains. The well-

known Korteweg-de-Vries (KdV) and Burgers equations are derived by using the reductive

perturbation method. The basic features (phase speed, amplitude, width, polarity, etc.) of DIA solitary

and shock waves are examined. The relative strength among dispersion, nonlinearity and dissipative

coefficients is also discussed. It is found that two distinct temperatures superthermal electrons and

arbitrarily charged dust play significant role on modifying the basic features of DIA solitary and

shock structures. The findings of our present investigation in some space and laboratory dusty plasma

environments are briefly discussed.

In many nonlinear systems, the interplay between the nonlinearity and dispersion leads to the

formation of a very robust coherent and localized structures, the solitons. In cylindrical symmetry, the

theory of the large amplitude waves predicts the existence of nonlinear ring waves, whose

spatiotemporal evolution is governed by the concentric (or cylindrical) Korteweg-de Vries (cKdV)

equation. Here, we present the approximate semi-analytical ring-soliton solution of cKdV equation

with standard boundary conditions. The cKdV equation describes the propagation of weakly nonlinear

and weakly dispersive ring waves in an incompressible, inviscid, and irrotational fluid. It is found that

the semi-analytical ring-soliton travels with time-varying amplitude and width, and phase which is

linearly dependent on space and time coordinates. It is also seen that there is a good agreement

between numerical and semi-analytical solutions.

The nonlinear propagation characteristics of dust-ion-acoustic (DIA) waves in dusty plasmas with bi-

Maxwellian electrons, namely, lower and higher temperature electrons (composed of negatively

charged stationary dust, inertial ions, and non-inertial two-temperature-electrons) were studied using

the reductive perturbation technique. KdV, mKdV and Gardner equations (both standard and modified

ones) were derived to investigate the basic features of planar and nonplanar DIA solitary waves [1-2].

Burgers equations (both standard and modified ones) were also employed to analyze the properties of

planar [3] and nonplanar DIA shock waves. The effects of magnetic field on the DIA solitary

structures were also discussed by analyzing the Zakharov-Kuznetsov equation [4]. The present

investigation may play important role in understanding the localized electrostatic disturbances in

space and laboratory dusty plasmas. References: 1. M. M. Masud, M. Asaduzzaman, and A. A.

In this study, Gd and Cr co-doped BiFeO3 multiferroic nano-ceramics were synthesized using sol-gel

method to investigate their structural and magnetic properties. Composition of Bi0.95Gd0.05Fe1–

xCrxO3 (x = 0, 0.02, 0.04, 0.06 and 0.08) was prepared from bismuth nitrate pentahydrate, Iron

Nitrate nona hydrate, gadolinium nitrate hexa hydrate and chromium nitrate nona hydrate with

appropriate calculated stoichiometry. Citric acid (C6 H8O7) as chelating agent was used as raw

materials and the deionized water was used as solvents. Obtained nano-ceramics were annealed at

various temperatures between 400-7000C following single-stage sintering. The investigated properties

were compared between undoped and Gd-Cr doped BiFeO3 nanoparticles. The X-ray diffraction

(XRD) patterns revealed that the doping of Gd in the place of Bi and Cr in place of Fe in BiFeO3

induces a tendency of phase transition from rhombohedral (R3c) to orthorhombic (pna21). The field

emission scanning electron microscopy images demonstrated that due to the substitution of Gd and

Cr, the average particle size was found vary from 25 to 200 nm depending on doping concentration.

Vibrating sample magnetometer (VSM) results confirmed improved ferromagnetic properties of

synthesized materials. A substantial enhancement of magnetization of 6 emu/gm was obtained for 5%

Gd and 6% Cr doped multiferroic.

Markovian Decision Process Analysis on Traffic Congestion at Dhaka City

Md. Abdur Rahman, and Md. Abdul Hoque


Although decentralization can promote good governance for achieving effective and socially

beneficial planning, it cannot be achieved in Bangladesh for lack of proper coordination. So, most of

the various kinds of important offices have been serving public from Dhaka. Thus a lot people have

been moving around Dhaka for their official works. Besides, people have the tendency to stay in

Dhaka for enjoying various kinds of better facilities exist here in education, healthcare, employment,

business, shopping, etc. As a result, Dhaka has huge population now and hence a lot of transports

have been prevailing here for transporting the public. Most of the residents of Dhaka has to spend a

lot of their valuable time in traffic jam, created by various kinds of factors such as huge number of

vehicles, illegal driving, illegal pedestrians crossing over roads, illegal loading and unloading beside

roads, unplanned bus stops, narrow roads, etc. So, transportation planning is essential to get rid of this

traffic jam and hence for the comfortable life of the residents of this city. Reduction of traffic jam is a

great challenge now. As we have not the opportunity of developing alternative transportation system

within a short time, there is a dire necessity of carrying out research on the current transportation

system in order to get rid of this traffic jam. Whatever may be factors for traffic congestion, we need

to find them out. Also, we are badly in need of carrying out research on how to improve this

transportation situation in Dhaka city. Here we discuss the parties/factors that are responsible for

traffic congestion and suggest for improvement in the city transportation networks. Then we carry out

Markov Chain Decision Analysis on this problem to increase the flow of vehicles so that congestion is

21

reduced. It aims to observe the different issues-making scenario and its effect on the urban

environment as well as to examine our markov chain decisions to reduce the traffic congestion.

Application of Probability Distributions for Wind Speed Modeling

Md. Moyazzem Hossain



Wind speed is the most significant parameter of the wind energy. However, the probability density

functions (pdfs) are usually used to describe the characteristics of wind speed. So, the accurate

determination of probability distribution of wind speed is very important in estimating wind speed

energy potential over a region. In literature, several pdfs has been investigated to justify the suitability

of modeling the wind speed in different regions all over the world. Therefore, the choice of the pdf is

very crucial. This paper, firstly find the estimates of the parameters of all probability distribution

considered in this study to describe wind speed characteristics by using the maximum likelihood

method and iterations were carried out with Newton-Raphson technique. Finally, the appropriate pdf

for monthly maximum sustained wind speed at Cox‟s Bazar in Bangladesh is selected with the help of

the Kolmogorov–Smirnov statistic, the coefficient of determination, the Chi-square statistic, Root

mean square error (RMSE), AIC and BIC. Results indicate that, among the distributions considered in

this study, the Skewed t (ST) distribution provide generally the best fit to the wind speed data.

E-mail: [email protected]

In the last era around the world weather prediction has been one of the most scientifically and

technologically challenging problems. Statistical techniques for rainfall prediction cannot perform

well for long-term rainfall forecasting due to the dynamic nature of climate phenomena. Data mining

techniques like Decision Tree (ID3), C4.5, C5, Multilayer Perception, K-nearest neighborhood (K-

NN), Naïve Bayes, Support Vector Machine(SVM),Classification and Regression Trees (CART),

Artificial Neural Network (ANN), Fuzzy logic, etc. has become very popular and most widely used

techniques for rainfall forecasting. In this study C5, Naïve Bayes and Support Vector Machine (SVM)

algorithm have been used for classification and predicting daily rainfall status. Confusion matrix is

also used in this study to calculate different accuracy measures, errors and precision to compare

among the techniques. From the result we find that the performance of C5 decision tree algorithm and

Support Vector Machine are better than that of Naïve Bayes algorithm considering the accuracy and it

is also observed that C5 and SVM gives more or less same accuracy. But on the basis of the value of

Kappa statistics, we find that C5 algorithm perform better than Support Vector Machine. Different

measurement error such as, mean absolute error and root mean squared error are also calculated to

compare these techniques. Relating the error measurement we can conclude that C5 algorithm gives

better result than others two techniques.

Multivariate GARCH model are frequently used in the analysis of dynamic covariance structure of

financial time series. BEKK model (named after Baba, Engle, Kraft, and Kroner, 1990) is the

extension of GARCH model. In some situations, sign of parameter are known in advance. For

example, variance, growth rate etc. cannot be negative. In such cases, usual unrestricted estimate are

not appropriate. In this paper we propose constraint based optimization technique to estimate

parameters of BEKK model to capture the sign or restriction on sign problems. We consider three

financial time series Export, Import and Exchange rate of Bangladesh and observe that our proposed

restricted likelihood method performs better than the usual likelihood method for the selected series.

Share Market is an untidy place for predicting since there are no significant rules to estimate or

predict the price of share in the share market. Many methods like technical analysis, fundamental

analysis, time series analysis and statistical analysis etc. are all used to attempt to predict the price in

the share market but none of these methods are proved as a consistently acceptable prediction tool.

Artificial Neural Network (ANN), a field of Artificial Intelligence (AI), is a popular way to identify

unknown and hidden patterns in data which is suitable for share market prediction. Another machine

learning algorithm Support vector machines (SVMs) are promising methods for the prediction of -

financial time series because they use a risk function consisting of the empirical error and a

regularized term which is derived from the structural risk minimization principle. Paper presents first

detailed study on data of Dhaka Stock Exchange (DSE) to predict the stock market volume of Dhaka

Stock Exchange (DSE). In this study, we have applied and compared salient machine learning

algorithms to predict stock exchange volume. The aim of this paper is to provide a review of the

applications of ANN & SVM in stock market prediction in order to determine what can be done in the

Ignorance of seasonal adjustment usually distorts the behaviour of time series analysis. On the other

hand, seasonally adjusted data provide more interpretable measures of changes in a given period of

time. In this paper, an attempt has been made to implement seasonal autoregressive integrated

moving average (SARIMA), filter, non-filter and X-based seasonal adjustment methods for

removing the seasonality in the time series data. We investigate the non-linear Neural Network

approach using back propagation algorithm which is widely used as a promising method for analyzing

time series data in the presence of seasonality. Neural Network approach is performed by selecting the

appropriate number of hidden layers and dividing the data into training and test set to measure the

different forecasting accuracy. It is observed that the Neural Network non-linear method performs

well and produces more accurate results compared to the other seasonal adjustment methods in time

series data.

Department of Mathematics, Bangladesh University of Engineering and Technology (BUET)


With the advancement of more and more sophisticated greenhouses all over the world, optimal control

of greenhouse horticulture has become imperative. This paper shows how mathematical methods can

be implemented to formulate guidelines for several processes that characterized the control of

greenhouse climate, such as crop growth and greenhouse climate change. The development of the

crop occurs on a time scale of weeks or months, whereas most of the greenhouse climate changes on a

daily basis. First, a simple mathematical model for the greenhouse system is presented including its

equipment, the crop, and also the heat input from the greenhouse heating system as control variable.

Next, it is based on a mathematical cost function that is either maximized or minimized. In our case

the cost function is profit, which must be maximized. The profit equals the money obtained from

selling the crops minus the costs required for maintaining a favorable greenhouse climate. The

Pontryagin‟s maximum principle is used to characterize the optimal controls. The optimality system is

derived and solved numerically using an iterative method with a Runge-Kutta fourth order scheme.

Landslide is one of the most vulnerable disaster in the mountain region like Himalaya. From the last

five decades, landslide becomes active every year in the time of monsoon in and around Darjeeling.

Places of landslides occurred during 2014 to 2016 has been marked using Google earth image. Slope

map and elevation map was created by SRTM (30m) data under GIS environment. Seismic record

confirms that the area is tectonically active and numerous faults, fractures, joints developed due to

Indian plate subducted under Eurasian plate which made the area geologically fragile. High slope,

high drainage density and heavy rainfall make the region prone to landslide. Anthropogenic activity

such as urbanization, deforestation, improper solid waste treatment makes the slope unstable.

Tannery industries are producing millions of tons of waste water and are major source of water

pollution. In this research work tannery effluents have been characterized and found to contain very

high biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solid (TDS),

turbidity and conductivity. The aim of this research is to treat tannery effluent in different way. In this

study we coagulated liming waste water with dyeing waste water at a different proportion. Various

tannery effluent water were used to identify the effectiveness of the research. The maximum removal

of biological oxygen demand BOD, chemical oxygen demand COD, dissolved solid TDS, turbidity

and conductivity were found to be 72.16‰, 87.60‰, 91.29‰ and 83.34‰ respectively. These result

were found to be effective in treating tannery effluent. Hence it was proven that tannery effluents can

be successive used for the treatment of tannery effluent.

and 98.34%, respectively for nutrient cultures. In the cultures using wastewater, the growth rate of S.

plantensis and C. vulgaris was 1008.62% and 688.23%, respectively whereas the chromium uptake

rate was 2461.86% and 1052.35%, respectively for nutrient cultures. The mean (±S.E.M) values of

chromium uptake efficiency by S. plantensis and C. vulgaris in wastewater cultures was 0.426

(±0.049) ppm and 0.466 (±0.029) ppm, respectively whereas chromium uptake efficiency by S.

plantensis and C. vulgaris in nutrient cultures was 2.971 (±1.58) ppm and 2.957 (±1.57) ppm,

respectively. The cultures using wastewater, the mean (± S.E.M) values for the growth of S.

plantensis and C. vulgaris was 0.227 (±0.084) mg/L and 0.166 (±0.91) mg/L, respectively whereas

the growth of S. plantensis and C. vulgaris in nutrient cultures was 0.554 (±0.079) mg/L and 0.254

(±0.104) mg/L, respectively. In nutrient cultures, the growth of two algal test species was significantly

different. The implications of these findings can be used in monitoring and remediation of chromium

from other industrial discharges.

Quantitative Approaches in the Field of Geosciences

Md. Sakawat Hossain, S.M. Mahbubul Ameen, and Rumana Yeasmin

Department of Geological Sciences, Jahangirnagar University


Nowadays, academic and professional geoscientists are using numbers, equations, and models in

conjunction with field observations, maps and words as fundamental tools for investigating Earth

processes in a highly quantitative manner. These new approaches have changed our traditional

attitudes of viewing geosciences as mainly qualitative previously rather than quantitative at present.

Quantitative approach to the geoscience prepares us to understand diverse topics such as geodynamics

and plate tectonics, active tectonics and geomorphology, climate change and sea-level rise, and much

more. However, here we focus only to the rock structures and textures. Fractures, faults and joints can

occur in any material and at all scales. Generally, they form complex patterns, i.e. are statistically self-

similar over a certain range of scale ('fractal'). Such patterns cannot be analysed by conventional

methods but are suitable for application of fractal-geometry techniques. Fragmentation patterns, i.e.

the purely geometric aspects of fractures and fragments, bear most information, pattern analysis

30

represents the 'core' of investigation of fractured matter and fracture-forming processes.

Fragmentation patterns are generally different (i) in different directions (anisotropy), (ii) in different

areas (inhomogeneity), and (iii) on different scales (scaling). Key methods for analysis are, fragment

size distribution, 2D box counting, Map counting, Cantor‟s dust, Automated modified Cantor-dust

method, Mapping of rock fabric anisotropy, Euclidian distance, and Intercept method. Fault damage

zones and associated fracture networks can be analysed based on fracture frequency data using

autospectral and wavelet analysis. To understand the number of deformation phases and their

successive occurrences, style groups, orientation groups and overprinting relationships of the

structural and fabric data can be quantified using non-linear approaches. A newly developed

structural-tectonic-geochronology framework, known as tectonic sequence diagram can be employed

to decipher deformation histories in more accurate way. Most of these quantitative computations and

their graphical visualization can be done using the MATLAB software and its user friendly toolboxes.

This software is used not only to provide numerous ready-to-use algorithms for most methods of data

analysis but also allows the existing routines to be modified and expanded, or new software can also

be developed. The MATLAB scripts, or M-files to solve typical problems in earth sciences, such as

simple statistics, time-series analysis, geostatistics, and image processing are available online. These

resources also demonstrate the application of selected advanced techniques of data analysis such as

nonlinear time series analysis, bootstrapping, image and terrain analysis. Finally, we can conclude that

applying quantitative techniques in understanding aspects of the Earth processes will be a major draw

into the discipline.

Meso-scale tectonic structures in part of Aravalli fold belt, northwestern India: implication to

paleo-stress analysis

Javed Ikbal, Syed Ahmad Ali

Aligarh Muslim University


Rocks of Aravalli fold belt are the result of poly-phase deformation. Deformed planner and linear

meso-scale structures such as joints, boudinage, crenulation cleavage and folds found in this area are

considered for paleo-stress analysis. The orientation of these brittle and ductile deformed structures

appraised the paleo-stress direction. Acute angle of conjugate joint set, direction perpendicular to the

boudin axis and crenulation cleavage (S2 plane), and obtuse angle of the folds or direction

perpendicular to the axial plane of folds is the direction of maximum principle stress (?1). The

geometric analysis (orientation) of all the structures reveals that the area is affected E-W

compressional stress due to compression of Bundelkhand and Marwar craton.

Characterization of Heavy Mineral Sand Deposits of Bangladesh

Eunuse Akon

Consultant, Geological Survey of Bangladesh, Pioneer Road, Segunbagicha, Dhaka, Bangladesh

Former Chief Geologist & Director, Bangladesh Atomic Energy Commission


The exploratory efforts over the last few decades by Bangladesh Atomic Energy Commission (BAEC)

in the south eastern coastal belt of Bangladesh for the heavy mineral sand deposits has resulted in the

discovery of seventeen deposits in the beach and off-shore islands covering mainly Teknaf - Cox‟s

Bazar –Moheskhali region of the coastal area. These deposits range from 500-10,000 feet in length,

31

50-1000 feet in width and 3-15 feet in thickness containing more than 4 million tons of heavy

minerals. These deposits are composed of fine to medium grained sand. The grain size of the heavy

minerals range from 0.075 mm – 0.25 mm. Heavy mineral percentage varies from deposit to deposit

ranging from 7.30% - 42.20%. On average mineral sand deposits contain 23% total heavy minerals.

Resource estimation shows that the heavy mineral sand deposits altogether contain 1.76 million tons

of economically important heavy minerals which are: ilmenite (1,025,000 tonnes), garnet (223,000

tons), zircon (158,000 tonnes), leucoxene (97,000 tons), kyanite (91,000 tons), rutile (70,000 tons),

magnetite (81,000 tonnes) and monazite (17,000 tonnes). Mineralogical composition of the heavy

fraction in the deposits is as follows: ilmenite 9.14 - 46.02%; garnet 4.40% - 8.05%; zircon 1.20% -

6.80%; kyanite 0.80% - 9.90%; rutile 0.44% - 4.00%; leucoxene 0.9% - 5.06%; magnetite 0.10% -

4.55% and monazite 0.05% - 1.20%. Occurrence of heavy mineral placer deposits in the Bay of

Bengal Islands under Bhola and Patuakhali districts and in the river sand bars of the Brahmaputra

River has been reported recently. The heavy mineral resource in the Brahmaputra river basins appears

to be huge. Mineral Processing activities on the bulk samples from different deposits have been

carried out in the pilot plant of BAEC at Cox‟s Bazar to characterize the separation characteristics of

individual heavy minerals using gravity, magnetic and electrostatic separators. Geochemistry of some

individual heavy minerals separated at the pilot plant have been compared with those of the

commercial grades. Few thousand tonnes of industrial heavy minerals namely zircon, rutile, garnet,

ilmenite, magnetite; produced during pilot plant studies have already been used in different industries

of Bangladesh. The heavy minerals found in the beach sands, river sand bars and in the Bay of Bengal

islands need to be mined sustainably and utilized for the socio-economic benefit of the country. These

minerals have large demands at home and abroad. Optimum utilization of the economic heavy

minerals found in the mineral sand deposits of Bangladesh will contribute significantly in economic

growth and industrial development of the country. These heavy minerals have large scale industrial

applications. Ilmenite, rutile and leucoxene are the source of titanium oxide which are extensively

used in pigment, paper and paint industries. They are used in manufacture of titanium metal. Because

of its excellent properties (lightness, strength, corrosion resistance and heat resistance) it is used

extensively in aerospace and aviation industries. Zircon is mainly used in the production of ceramic

tiles, refractory and sanitary ware. Monazite is the source of rare earth elements. Thorium metal from

monazite has application in nuclear industry fuel assemblies. The Garnet is widely used in making

various emery papers and cloths, emery wheels and grinding stones.

Miocene Reservoir Study, Mid-Eastern Bangladesh

Abdus Samad Azad, Zabir Hossain, and Edwin Bowles

Kris Energy Bangladesh Ltd.


We represent our experience of studying Miocene reservoir sandstones of an anonymous gas field

from the mid-eastern part of Bangladesh. Due to data security policy, we kept the structure and well

names obscured and focused only on scientific observations. 3D seismic data supplemented with well

logs, drill cuttings and core data were used to interpret our observations. We used IHS Kingdom 2017

for seismic interpretation and GS software for well correlation. The reservoir sandstones of the

studied structure are easily correlateable throughout the area because of their high amplitude, sub-

parallel to parallel, continuous banded reflection pattern. However, these reservoir sandstones are

often intervened by large-scale canyons/valleys. Reservoir potentiality drastically reduced where the

sandstones are eroded by these mud-filled canyons. Our interpretation suggests that these sandstones

were deposited at the High Stand of sea level condition and predominantly consists of thin bedded

deltaic sandstones. On the other hand, highly incised valleys were formed during extreme low sea

level condition and remained sediment starved during the entire low stand period. They were filled in

32

the successive late transgressive or High Stand stage. The reservoir sandstones of the studied structure

are also well correlateable in the drilled wells. Gamma log response within these reservoir sandstones

varies from cleaning-up trend (funnel shaped) to dirtying-up trend (bell shaped) and probably

deposited as mouthbar deposits or inter-distributary bay fill deposits. Lithofacies interpretation from

core data also confirms electrofacies observation. These fine-grained sandstones typically represent

mouth-bar sedimentary facies and contain sedimentary structures e.g., planner lamination, ripple cross

lamination, minor thin mud-interclasts, lenticular and flaser bedding and minor plant debris. Trace

fossils e.g., planolites, escape burrows and opiomorphaare also common. The reservoir quality is

considerably affected both by these sedimentary features and bioturbations. Sedimentary features like

flaser and lenticular bedding, mud-interclasts, wavy ripples acted as baffles and reduced vertical

permeability. Bioturbations also resulted into poor-connectivity of the macro-pore network and

restrained fluid flow within the reservoir zone. Thin section and SEM analysis of the core samples

suggest a moderate to moderately good total porosity. The reservoir comprises of small inter-granular

pores, minor dissolution pores, and micro-porosity associated with clay mineral aggregates, mica-

laths, organic materials, microcrystalline and corroded framework grains. Pore throats are commonly

constricted by grain-coating clays, organic materials, mica laths, detrital clay resulting in moderately

low to poor permeability. Kaolinite is present in minor to moderate amounts and occur as small pore-

lining verms and sheets. Chlorite occur as grain-coating or pore-filling platy aggregates and clumps

which also results low permeability. Pore throats sometimes are constricted by quartz-overgrowth and

restrained permeability. Feldspar-overgrowth, microcrystalline aggregates and very fine framboids of

pyrites, galena and rutile also affected the poor-network and hindered the fluid flow.

Nanocomposite Nd4-xTbxFe71+yCo5Cu0.5Nb1B18.5-y (x = 0.4, y=0 and 12.5) ribbons were

prepared by melt spinning technique with constant wheel speed of 40 m/s. The samples have been

annealed in an evacuated quartz tube using a pressure of around 10-5 mbar for 10 minutes at different

crystallization temperatures like 675oC, 687oC, 700oC, 712oC, 725oC for Nd4-

xTbxFe71+yCo5Cu0.5Nb1B18.5-y (x = 0.4, y=12.5) and 600oC, 625oC, 650oC, 675oC, 700oC for

Nd4-xTbxFe71+yCo5Cu0.5Nb1B18.5-y (x = 0.4, y=0) respectively, which are found by differential

scanning calorimetry (DSC). Crystallization behavior was studied by X-ray diffraction (XRD) using

CuK? radiation (1.5418 Å). 57Fe Mössbauer spectrometry in transmission geometry with constant

acceleration spectrometer. The 57Fe Mössbauer spectra were recorded at room temperature. The

ribbon samples were also characterized by vibrating sample magnetometer (VSM). Tb substitution

has significantly enhanced the value of coercivity (Hc) and maximum energy product (BH)max.

Highest value of Hc and Mr/Ms have been obtained as 3.66 kOe and 0.78 for the sample of

composition Nd4-xTbxFe71+yCo5Cu0.5Nb1B18.5-y (x = 0.4, y=0) annealed at 675oC and 700oC for

33

10 min. At 625oC maximum energy product (BH)max has been found to be 9.37 MGOe for the

sample of composition Nd4-xTbxFe71+yCo5Cu0.5Nb1B18.5-y (x = 0.4, y=0). The M-H hysteresis

loops show extremely soft natures which do not possess any area. However, with the annealing of the

samples in the above mentioned temperature evolution of large coercivity was observed due to the

formation of exchange couple hard and soft nanocrystal composites.

Effects of vortex-like ion distribution on dust-acoustic solitary waves in a

self-gravitating opposite polarity dust plasma medium

A. Paul, G. Mandal, A. A. Mamun, and M. R. Amin

A self-gravitating opposite polarity dust plasma (SGOPDP) medium (containing both positively and

negatively charged dust, vortex-like distributed ions and Maxwellian electrons) have been considered

in order to examine the effects of vortex-like (trapped) ion distribution on dust-acoustic (DA) solitary

waves (SWs) propagating in SGOPDP medium. The reductive perturbation method,

which is valid for small but finite amplitude SWs, is employed to derive a modified KdV equation

having stronger non-linearity. The basic features of the DA SWs in SGOPDP medium are found to be

significantly modified by the combined effect of self-gravitational field and vortex-like ion

distribution. The results of this paper have many implications in space and laboratory dusty plasmas.

Md. Abdul Mannan Chowdhury


The Voltage and Over-Load Current Protector for Three Phase Motor has been designed and

developed with upper and lower voltages set at ± 2% of the normal voltage (220V AC) respectively.

The hysteresis for both the upper and lower cut off voltage levels is only about 03 volts. The time

delay feature of this device enables the load to be switched ON only when the supply voltage is stable

and lies between ± 2% of its normal voltage (220V AC). The voltage detector gives the output high

voltage when all the three phase voltages are equal and within ± 2% of the normal voltage. When the

load current exceeds the presets value, the motor is deactivated and realizing this problem an over-

load protector circuit is designed with the help of relay and comparator circuit. The over-load current

sensing circuit is used by Hall Effect principle. The load current display circuit is designed with the

help of load current sensor and analogue panel meter. The AC input voltage variations are displayed

on a linear scale volt meter which ranges from 0-300 volts.

Instability and Growth of Temperature, Rainfall and Humidity in Bangladesh

Md. Meshbahur Rahman, Mohammad Aminul Kaiser, and Kanis Fatama Ferdushi



Climate change is the long-term effects of change in temperature, rainfall, and humidity etc. as well as

the change of average weather conditions. This study attempts to measure the instability and growth

in temperature, rainfall and humidity of Bangladesh based on the secondary data for different

geographic location during the period 1947 to 2016 collected from Bangladesh Meteorological

Department (BMD). To conduct this study, different statistical tools such as independent sample t-

test, linear regression model to examine the change of temperature, semi-log function to work out

growth rate have been used. The analysis shows that there is an increase in temperature but rainfall

and air humidity has decreased during the study period. It is also revealed that temperature is

negatively correlated with the rainfall and humidity. There is an unstable change in the amount of

rainfall, humidity, and temperature during the study period. Rainfall shows more instability than

temperature. Although, the trend of temperature, rainfall and humidity are not rapid but it may be a

big future thread if proper attention and policy are not taken from now.

Sayeed Sabbir Ahmed

Jahangirnagar University, Dhaka

In this paper we consider base stock stochastic perishable inventory system in open Jackson network

at a service facility with a infinite waiting room. In this network we proposed single server at each

node with attached inventory where each node represents a queue in which different nodes have

different service rates and state-dependent service rates change depending on queue lengths. Service

times are exponential distributed. Customers arrive in the system according to a Poisson process.

There is no priority in serving the customers. All customers at each node are served on a first-come,

first-served basis. For this system arriving customers form two waiting line based on the order of their

arrivals. The maximum storage capacity for th warehouse is fixed as when the on hand inventory

level drops to a prefixed level an order for units is placed. In this model the replenishment of

inventory is instantaneous i.e. demand is refilled one unit at a time. The items of inventory have

exponential life times. Matrix Analytical method (MAM) is applied for this system. The proposed

method is quite efficient and practically well suited for accurate performance estimates. The joint

probability distribution of the number of customers in the system and the inventory level is obtained

in the steady state case. Some important system performance measures in the steady state are derived.

A suitable cost function is defined and analyzed. The total expected cost rate is also calculated.

Sensitivity analysis has been carried out to study the effect of variation of parameters. Some

numerical and graphical illustrations are provided.

Optimal production model with quality sensitive market demand, partial backlogging and

permissible delay in payment

Brojeswar Pal, Mathematics

The University of Burdwan


In this study, we consider an imperfect production inventory system with quality of the products

dependent market's demand structures and allowable delay in payments. Two alternative approaches

of trade credit policies have been discussed when the manufacturer could not pay the due amount to

the supplier within the credit period offered. Here, a new cycle is begun with new production when

the manufacturer's inventory touches to a certain level of shortages. The cycle also ends when

backlogged inventory level is reached a certain level. The backlogging rate for the player is dependent

on waiting time. The production cost of the manufacturer varies with ordering lot size and quality of

product. The behavior of the model under integrated system is analyzed. The sensitivity of the key

parameters is examined to test feasibility of the model. Finally, a numerical example is provided to

investigate the proposed model.

Impact of Submarine Landslides in Water Reservoirs: Variation of Height of Obstacles

Jeevan Kafle, and Bhadra Man Tuladhar

Here, we apply a comprehensive and general two-phase, physical-mathematical mass flow model

(Pudasaini, 2012) that consists of non-linear and hyperbolic-parabolic partial differential equations for

mass and momentum balances and present three-dimensional, high-resolution simulation results for a

real two-phase debris mass impacting a fluid reservoir, akin to hydroelectric power plant. Besides

buoyancy, the model includes some dominant physical aspects of the debris flows such as generalized

drag, virtual mass and non-Newtonian viscous stress as induced by the gradient of solid-volume-

fraction. In the simulation results, we consider three dimensional circular bumpof different heights

with fixed radius and at the same location, the intense flow-obstacle-interaction dramatically reduces

the flow momentum resulting in the rapid energy dissipation around the obstacle. With the increase of

36

obstacle height, overtopping decreases, but the deflection and capturing (holding) of solid mass

increases thereby decreasing moving mass both in amount and speed. These results may help for the

proper modeling of landslide and debris induced mountain tsunamis in rapidly changing slopes, the

dynamics of turbidity currents and highly-concentrated sediment transports in fluid reservoirs in high

mountain slopes, channels, and reservoirs. These results may be extended and applied to hazard

mitigation and in solving relevant engineering and environmental task.

Dynamic flow-obstacle-interaction using quasi-two-phase mass flow model

Khim B. Khattri, and Bhadra Man Tuladhar

The newly constructed generalized quasi-two phase bulk model (Pokhrel et al., 2017)describes some

fundamentally new mechanical and dynamical concepts of generalized bulk and shear viscosities,

pressure, velocities and flow depth. Here, we present some computational strategies and discritization

of the model that involves higher order central differences and donor-cell method. Appropriate

rheological and boundary conditions are constructed, including the pressure- and rate-dependent

Coulomb viscoplastic deformation and sliding for the mixture, and von Neumann boundary condition

for the bulk pressure. Some high resolution simulation results are presented for the flow geometry,

mixture velocities and impact pressures with the marker-and-cell method when a debris mass is

released from a debris box down the channel that encounters a vertical wall in different positions,

slopes and material composition. Our results reveal that the new generalized quasi two-phase model is

capable of acquiring the interacting mixture velocities with vertical wall, its overtopping and

detachments with the bed.These dynamical quantities play crucial role in the description of the flow,

and thus enhances our understanding in more efficiently describing the mixture flows in natural

slopes, in the form of landslides, debris flows, particle-fluid transports in hydraulic reservoirs and

channels as well as in industrial mass flow.

Interaction of Two-Phase Debris Flow with Lateral Solid Walls: Dynamic Impact Pressure and

Contraction Ratio

Parameshwari Kattel, and Bhadra Man Tuladhar

Landslides, debris avalanches and debris flows are common mass wasting phenomena in mountain

slopes.Debris flows can increase their volume and destructive potential by scouring undermining banks,

thereby bringing morphological changes. Construction of lateral shear walls as embankments is a way of

mitigation. In natural debris flows, solid and fluid evolve dynamically differently and show different

interaction with obstacles. So, we employ a general two-phase mass flow model (Pudasaini, 2012)

consisting of a set of highly non-linear and hyperbolic-parabolic PDEs for mass and momentum

balances for both downslope and cross-slope directions. Besides buoyancy, the model includes the

dominant physical aspect of the flow: virtual mass force, generalized drag and non-Newtonian

viscous stress. Our numerical experiments show that the solid is more obstructed than the fluid when

a debris flow passes over a system of converging lateral shear walls resulting in different flow-

37

dynamics, wall-interactions and deposition morphology of the phases.The dynamic impact pressure

and the novel barycentric impact pressures from the phases are also computed. Narrower the slit, more

is the obstruction. The obstruction is related with the contraction ratio of the shear walls. These

computations and the observations increase our understanding of the flow dynamics and interactions

with the lateral shear walls. The results may be extended further to achieve some engineering

solutions to hazard mitigation in debris-flow prone zones.

Generalized Quasi Two-Phase Mass Flow Model: Derivation and Description

Puskar R. Pokhrel, and Bhadra Man Tuladhar

We have employed the full dimensional two-phase (solid particles and viscous fluid) mass flow model

(Pudasaini,2012), to generate a novel and generalized quasi two-phase, full two-dimensional model

for bulk mixture flow down a channel. The emerging model is written as a well-structured system of

three highly non-linear partial differential equations in conservative form representing the mass and

the momentum balances in the downstream and the vertical direction. The new mechanical and

dynamical concepts of generalized bulk and shear viscosities, pressures, and velocities for the mixture

characterize the model. A new reduced model is also obtained by considering the identical velocity

drift factors in the generalized model. The advantage of this model lies mainly in providing a

possibility for simulating thedynamical variables much faster than the two-phase mass flow modeland

much accurate than the classical bulk mixture model. We also introduce the velocity drift model

which is the function of the shear viscosity of the bulk mixture model. The newly developed rheology

of the mixture model as to be presented here plays crucial role in the two phase flow dynamics. The

introduction of the velocity and pressure drifts factors makes it possible to reconstruct the two-phase

mass flow so as to capture its basic dynamics.

In this paper, we define mask as a transformation that transform real numbers, triangular fuzzy numbers,

trapezoidal fuzzy numbers and intuitionistic triangular fuzzy numbers into an intuitionistic trapezoidal

fuzzy number by keeping the original properties of the respective numbers. To discriminate fuzzy

alternatives, we also define a new type of ranking function for trapezoidal intuitionistic fuzzy numbers

considering both the membership and non-membership properties of the numbers. Using these definitions,

we formulate mixed type trapezoidal intuitionistic fuzzy transportation problem.

E-mail: [email protected]

The physics of dusty plasmas and some open issues in dusty plasma models for the study of dust-ion-

acoustic (DIA) solitary and shock waves are addressed. It has been pinpointed that i) derivation of ion

current along with ion density, ii) derivation of Korteweg-de Vries-Burgers equation, and iii)

inclusion of the effect of external magnetic field in existing literature, are not correct in general. The

dusty plasma model is simplified (by using some reasonable assumptions), and the basic features of

the DIA solitary and shock waves are identified. The experimental observations of the identified basic

features of the DIA solitary and shock waves are briefly discussed.

Facile Synthesis of Thiacalix[n]thiophene derivatives

Masashi Hasegawa

School of Science, Kitasato University, Sagamihara, Kanagawa 252-0373, Japan

Thiacalix[n]thiophenes, which are consisting of sulfur-bridged oligothiophenes, have cavitand

structures. However, their synthesis was often performed under the constraint of a difficult cyclization

reaction. Here, we present a facile synthesis of a series of novel thiacalix[n]thiophenes (2) and

thiacalix[n]dithieno[3,2-b:2‟,3‟-d]thiophenes, 3 (n=4–10). The detail of the cyclization reaction is

depicted in Scheme 1. A palladium-catalyzed coupling reaction of stannyl sulfide (Bu3Sn)2S and

dibromothiophene/dibromodithienothiophene (dibromo-DTT) derivatives gave the corresponding

macrocycles in good yield (Scheme 1). After the straightforward separation on a GPC, various sizes

of the macrocycles of 4–6mers for 2 and 4-10 mers for 3a–g together with acyclic polymers were

obtained. In this reaction, the substituents at the β-position could play a key role in effective

cyclization.

Scheme 1. Synthesis of thiacalix[n]thiophenes (2) and thiacalix[n]dithienothiophenes (3)

X-ray analyses of 3a and 3b revealed the molecular structures of square- (3a) and pentagonal-shaped

macrocycles (3b), respectively. Unlike conventional calixarenes, they exhibit distinct electron-

donating properties. In the cyclic voltammograms, reversible multi redox processes, owing to

electronic delocalization, were observed at low oxidation potentials. Compound 3a acted as a “Janus-

39

head” cavitand for two C60 molecules, whereas the 3b and 3c formed stable 1:1 complexes with C60

(Figure 1).

delay feature of this device enables the load to be switched ON only when the supply voltage is stable

and lies between ± 2% of its normal voltage (220V AC). The voltage detector gives the output high

voltage when all the three phase voltages are equal and within ± 2% of the normal voltage. When the

load current exceeds the presets value, the motor is deactivated and realizing this problem an over-

load protector circuit is designed with the help of relay and comparator circuit. The over-load current

sensing circuit is used by Hall Effect principle. The load current display circuit is designed with the

help of load current sensor and analogue panel meter. The AC input voltage variations are displayed

on a linear scale volt meter which ranges from 0-300 volts.

Identifying Differentially Expressed Genes Using Mode Fold Change

Md. Fazlul Karim Patwary


With the development of microarray technology, scientists can now measure the expression levels of

thousands of genes simultaneously in one single experiment. The problem of identifying differentially

expressed genes can be defined as: given gene expression measurements from two conditions, find a

Figure 1. ORTEP drawing of 1•2C60

40

subset of all genes having different expression levels across these two conditions. Analysis of

genomic data is challenging due to high dimensionality of data and low sample size. Currently several

mathematical and statistical methods exist to identify differentially expressed genes. So Microarray

technology has become one of the most important tools for genomic measurements. The technique has

been successfully applied to many areas in modern biology such as cancer research, identification of

drug targets, and categorization of genes involved in the cell cycle. The analysis of microarray data is

difficult due to the vast dimensionality of data and the high levels of noise. The need for solid

statistical methods is therefore strong. This study tries to describe a statistical methods for the

identification of differentially expressed genes in microarray experiments. Many methods have been

suggested for improvement. However, the most popular methods such as Significance Analysis of

Microarrays (SAM), samroc, fold change, and rank product. But those are far from perfect. In order to

determine which method is most powerful, it depends on the characteristics of the sample and

distribution of the gene expressions. The most experienced method is usually SAM or samroc but

when the data tends to be skewed, the power of these methods decreases. A comparison of the

performance of popular testing procedures for identifying differentially expressed genes from

microarray data such as SAM, samroc, fold change and rank product was performed. Modifications

were attempted on fold change, replacing the mean gene expression values with the median. It has

been observed that, fold change and the modified median fold change were consistently the top

performing methods for lognormal data. As the mode is the point of global maximum of the

probability density function we can replace the median of fold change with mode and we can call it

mode fold change. Then the result will be compared with previous to see the efficiency. In this study

we will try to find a flexible alternative method to identify differentially expressed gene.

Investigation of the dynamical behavior in a three component SIRS Model

Md. Shahariar Hossen and M. Osman Gani



In this work, we analyze the stability of periodic traveling wave of the two-component modified

FitzHugh-Nagumo(reaction-diffusion type) model of cardiac cell dynamics. The model equation

captured some essential dynamical feathers of a quantitative electrophysiological model of the cardiac

cell. It exhibits spiral wave in two space dimensions. It is important to understand periodic traveling

waves instability for describing the spiral wave instability resulting from the model. We ascertain the

existence of periodic traveling waves and its stability in the model as a function of the diffusion

coefficient of activator variable. In addition, we reckon the stability boundary of stable and unstable

periodic traveling waves in a two-dimensional parameter plane. It is observed that the periodic

traveling waves express instability by a stability change of Eckhaus type. As a result, a stable wave

bifurcates to oscillating periodic traveling waves. We describe the stability by calculating the essential

spectra of the waves.

The transportation problems consist of finding a model of shipments between origins and destinations

such that the total transportation cost is minimized. In the iterative solution procedure of

transportation problems, an initial basic feasible solution is prerequisite which ultimately leads to the

optimal solution in a finite number of steps. In this paper, we propose a new method to obtain an

initial basic feasible solution for the transportation problems. A comparative study by means of

example is also carried out to justify the performance of the proposed method. It is observed that the

performance of proposed method is remarkable for obtaining an initial basic feasible solution for the

transportation problems.

The unsteady MHD viscous compressible fluid flow past a semi-infinite vertical porous plate

surrounded in a porous medium with induced magnetic field has been studied numerically. The non-

linear partial differential coupled equations, governing the problem under consideration, have been

transformed by using usual transformations into a system of ordinary differential equations, and

solved numerically by applying the explicit finite difference method. We have used MATLAB as a

tool. The solutions for the density, velocity, induced magnetic field as well as temperature

distributions are discussed with respect to graphs obtained by using MATLAB. Finally, the important

Faculty of Engineering, Saitama University, Saitama, Japan

Development of micro-windmill as an alternate source of energy are increasing day by day to

encounter the energy demand close to the residential area e.g. on rooftops. To install wind turbine

near a residential area, it is always an important issue to ensure the structural stability, noise reduction

and slow rotating speed in terms of safety consideration. Considering all these factors, slow flapping

type wind turbine should be a desired solution for these problems.

42

Compare to the traditional rotating wind turbine, we attempt to develop a new concept regarding

energy extraction by adopting a flapping mechanism, such application has the prospect of utilizing the

wind energy in residential area or rooftops. In comparison with the traditional mechanics, a unique

flapping motion to extract wind energy has been considered and it gives an exciting proposition for

the wind turbine as it can deliver the predictable amount of energy. We developed a flapping type

wind turbine with introducing Chebyshev-dyad link mechanism by which the symmetric wing blade;

NACA0012 can transform the wind energy to mechanical rotation through the unique trajectory. The

design has been confirmed by optimizing different parameters with better performances. The turbine

performance obtained from numerical estimation exhibited a good feasibility which made the

appreciation of our experimental investigation. In this report, we investigate the prototype wind

turbineexperimentally. Also, the basic performances obtained from numerical simulation and

experimental investigations are compared.

Geochemical composition (major, trace and rare earth element concentration) has been studied for

sandstones from the Pliocene Tipam and Plio-Pleistocene DupiTila Formations of the Chittagong

Tripura Fold Belt (CTFB) - the eastern folded flank of the Bengal Basin to infer provenance, tectonic

setting and source area weathering. The Tipam and DupiTila sandstones have high SiO2 content

(80.80 – 93.79% with an average of 84.18%) compared to underlying Miocene Surma sediments and

moderate to low Al2O3 (10.01 – 2.87%, average 7.78%) content, with very low concentrations of other

major elements. Compared to the upper continental crust (UCC), these sandstones are enriched in

SiO2 and K2O, and depleted in Fe2O3, Al2O3, CaO and Na2O. The REE distribution pattern as well as

different geochemical discriminations (e.g., Cr/V vs. Y/Ni, Th vs. Sc, and La/Th vs. Hf) for the Tipam

and DupiTila sandstones are the suggestive of felsic granitic source area experiencing moderate to

intensive chemical weathering (Chemical index of alteration (CIA) ranges from 57 to 81 (average 72).

These sediments preserve the signatures of a recycled provenance related to an active continental to

passive margin settings.

Cu(II) and Fe(III). The analysis of the spectroscopic data shows that pyridine act as monodentate,

coordinating through the nitrogen atom of the pyridine ring. Complexes exhibit 4 and 6 coordinate

geometry respectively. The results of the antimicrobial studies showed that the metal complexes have

bromide and benzyldimethylhexadecylammonium chloride in aqueous/urea solution at various

temperatures

Md. Anamul Hoque


A study of the mixed micelle formation between tetradecyltrimethylammonium bromide (TTAB) and

benzyldimethylhexadecylammonium chloride (BDHAC) has been carried out in the absence as well

as presence of urea using conductivity technique. The values of critical micelle concentration (cmc),

degree of dissociation (g), micellar mole fractions (X), interaction parameter (?) and thermodynamic

parameters of the mixed surfactant system have been evaluated in this study. The evaluated values

were examined in accordance with Rubingh model. The obtained values of critical micelle

concentration (cmc) were smaller than cmcid values suggesting attractive interactions between the

constituents of solution. The micellar mole fractions (X1Rub) of BDHAC, estimated by Rubingh

model, were always higher than their ideal values (X1id) suggesting the high contributions of

BDHAC in mixtures of TTAB and BDHAC. Activity coefficients (f1Rub and f2Rub) were always

smaller than one in all cases and it indicated the attractive interaction between TTAB and BDHAC.

The values of ?Gom are found to be negative in all the cases which indicate the spontaneous

formation of mixed micelle. The values of ?H0m are negative in almost all cases indicating the

exothermic process. The values of ?S0m are positive in case of aqueous medium and 500 mmol.kg-1

urea solutions but found to be negative in attendance of 1000 mmol.kg-1 urea. The values of excess

free energy of micellization (?Gex) were also estimated and achieved to be negative showing the

stability of mixed micelles.

Md. Siddique Hossain

Eastern University, Bangladesh

Md. Sharif Uddin

Department of Mathematics Jahangirnagar University, Dhaka, Bangladesh

In this paper a time dependent inventory model is constructed basing on constant production rate. The

exponential demand rate decreases gradually. It develops to find total optimum cost, where the

products are having finite life, and thereby it allows the item‟s decay. Production starts with no

backlogs. Reaching at the desired level of inventories, it stops its production and then, due to demands

along with the decay it initiates its depletion. After certain periods the inventory becomes vanished.

The objective of this model is to find out the optimum inventory cost and optimum time cycle. The

model has also been justified with proving the convex property and by giving a numerical example.

Numerical Analysis on Heat Transfer Augmentation using ag-water Nanofluids

M. M. Billah, M. Sharif Uddin, M. N. Islam, and Aminur Rahman Khan


Nanofluids have been introduced for the augmentation in the heat transfer phenomena in the last few

years. A prodigious importance has been shown to the mixed convection heat transfer phenomena as

it has a very wide range of application in heat exchangers, solar collector, electronics cooling,

desalination process and so on. The behavior of nanofluids is explored numerically in an inclined lid-

driven triangular enclosure heated on bottom surface to gain insight into convective recirculation and

flow processes induced by a nanofluids. The present model is developed to examine the behavior of

nanofluids considering the solid volume fraction δ. Fluid mechanics and conjugate heat transfer,

described in terms of continuity, linear momentum and energy equations, were predicted by using the

Galerkin finite element method. Numerical results are obtained for a wide range of parameters such as

the Richardson number, and solid volume fraction. Ag-water nanofluids are used with Prandtl

number, Pr = 6.2 and solid volume fraction δ is varied from 0% to 10%. The streamlines, isotherm

plots and the variation of the average Nusselt number at the hot surface as well as average fluid

temperature in the enclosure is presented and discussed in detailed. It is observed that solid volume

fraction strongly influenced the fluid flow and heat transfer in the enclosure at the three convective

regimes

The tannery industries of Dhaka city have been relocated from Hazaribagh area to the Savar and

Keraniganjupazila due to adverse environmental hazard. The present study was carried out to

investigate the site characteristics of the relocated tannery project area through geo-environmental

analysis to identify the future risk and groundwater vulnerabilities. Furthermore the objectives of this

study were extended to bore log analysis, satellite data interpretation, assessment of groundwater

vulnerability and contaminant transport modeling. The results of this study showed that geologically

the area has huge thickness of alluvium and absence of Madhupur Clay Formation up to 20 m depth.

Geomorphological studies indicate that the area is situated around a very dynamic fluvial environment

and has been evolved through point bar accretion only within last 40 years. However, the shallow

depth of groundwater, loose sediments and absence of clay layer rendered the area very susceptible to

groundwater pollution. A fully integrated modeling package Visual MODFLOW and MT3D was used

in the study. The model showed that if the contaminant can reach the groundwater of the area, the

steep hydraulic gradient towards the Dhaka city will aid the flow and such plume will reach the

pumping well of the city within 51 years. To avert such anthropogenic hazard precautionary measures

like the use of geo-membrane and hydraulic barriers especially beneath the central effluent treatment

plant is very necessary.

Chikungunya fever (CHIKF) is caused by Chikungunya virus (CHIKV) which is an arthropod-borne

virus of alpha-virus genus and Togaviridae family. Initially, the virus is transmitted to human through

the bites of infected female Aedes mosquitoes namely Aedes Aegypti and Aedes Albopictus. In

Bangladesh particularly Aedes Aegypti is responsible for the transmission of Chikungunya virus. The

objectives of the study are to propose a dynamic model on the transmission of Chikungunya virus in

Bangladesh and to analyze the mathematical model of Chikungunya virus transmission. We present

two preliminary models that consists of the SEIR model for human (host) populations and SEI model

for mosquito (vector) populations. We calculate Basic Reproduction Number and perform Positivity

and Equilibrium States. The numerical simulations are done in order to illustrate the behaviors of

transmission of diseases for different values of parameters.

Infectious diseases are very common nowadays hampering the economical development of a country.

A highly devastating mortality rate can be experienced in every year for such diseases. Therefore,

prevention is quite necessary on right time since there have no proper treatment facilities in the

developing countries like Bangladesh. In that situation, media can play a vital role by raising public

awareness, telecast valuable programs during the outbreak period showing the harmful effects of

infectious diseases. The aim of this paper is to introduce a dynamic model regarding infectious

diseases where media works as a control function. The model has been analyzed to test the validity of

its well-posedness and the analytical results have been verified with the numerical simulations. The

findings of this paper show the importance of media that can be used to increase consciousness among

the general population during an infectious period.

Climate change is the long-term effects of change in temperature, rainfall, and humidity etc. as well as

the change of average weather conditions. This study attempts to measure the instability and growth

in temperature, rainfall and humidity of Bangladesh based on the secondary data for different

geographic location during the period 1947 to 2016 collected from Bangladesh Meteorological

Department (BMD). To conduct this study, different statistical tools such as independent sample t-

test, linear regression model to examine the change of temperature, semi-log function to work out

growth rate have been used. The analysis shows that there is an increase in temperature but rainfall

and air humidity has decreased during the study period. It is also revealed that temperature is

negatively correlated with the rainfall and humidity. There is an unstable change in the amount of

rainfall, humidity, and temperature during the study period. Rainfall shows more instability than

48

temperature. Although, the trend of temperature, rainfall and humidity are not rapid but it may be a

big future thread if proper attention and policy are not taken from now.

This research deals with the treatment of Chlamydomonas by generation of high voltage discharge

plasma at water surface. Chlamydomonas reinhardtii is unicellular green algae grows on water surface

of ponds or lakes over the Bangladesh and in other countries. These are causing several adverse

effects for human and other animal beings. We have applied high voltage discharge plasma for the

treatment of Chlamydomonas using point to plane electrode configuration. A high voltage test

transformer (Model No. HV 9000, TERCO, 50Hz, rated secondary voltage: 140kV) is used as a high

voltage supply source for generation of discharge at water surface. High voltage electrical discharge

in or above water has been considered as an effective method of water treatment to kill

microorganisms, negating the use of chemicals such as chlorine that leads to disinfection by-products

which may additionally compromise human health. It is found that high voltage discharge plasma

plays a key role for treatment of harmful algae help to remove microorganisms from water.

since the deposition of its parent materials. A soil-geomorphic map has been prepared based on soil

resource maps, physiographic maps, toposheets and satellite images consisting thirteen (13) soil-

geomorphic units from the study area. Soil-geomorphic units are checked in the field for ground

truthing of the unit boundaries; and samples have been collected from those soil-geomorphic units for

laboratory analyses. Based on field characteristics of soils particularly solum thickness, ped

development and cutan development in the B-horizons of the soil profiles from different soil-

geomorphic units, and relative ages of the soils a soil chronoassociation have been developed for the

An experimental evaluation of the direct and indirect effects of endemic seaweeds, barnacles,

and invertebrate predators on the abundance of the introduced rocky intertidal barnacle

Balanusglandula

Takashi Noda, and A. K. M. Rashidul Alam

The barnacle, Balanusglandula has recently invaded along the Pacific coast of eastern Hokkaido,

Japan. To evaluate the direct and indirect effects of endemic seaweeds, barnacles, and invertebrate

predators on the abundance of B. glandula on the rocky intertidal coast of eastern Hokkaido, we

conducted a field experiment from June 2011 to October 2012 in which we manipulated the presence

or absence of these factors. Seaweeds showed no significant effect on the abundance of B. glandula.

The endemic barnacle Chthamalusdalli and the invertebrate predator Nucella lima reduced the

abundance of B. glandula. However, the simultaneous influence of N. lima and C. dalli was

compensative rather than additive, probably due to keystone predation. These findings suggest that

competition by the endemic barnacle C. dalli and predation by the invertebrate predator N. lima

decreased the abundance of B. glandula, but that N. lima predation on C. dalliweakened the negative

influence of C. dalli on B. glandula. The implications of these findings are twofold: the endemic

competitor and invertebrate predator may have played important roles in decreasing the abundance of

B. glandula in natural habitats, and conservation of endemic invertebrate predators may be crucial to

impede the establishment and survival of introduced barnacles in rocky intertidal habitats.

warranty is provided for limiting period of time. In most of the inventory models, a single stock is

considered from where items are served for the customers. Here two stocks are considered. First one

is for fresh items and the second one is for returned items. It is assumed that inventory level for the

fresh and returned items are pre-determined and finite. When inventory level reaches at s

replenishment takes place with parameter ?. Arrivals of customers for fresh items form a Poisson

process with parameter ?. When inventory level reaches zero due to demands for fresh items, further

This paper presents a production-inventory model involving variable demand with normal distributed

lead time for deteriorating item. At first, we fuzzify the normal distribution of lead time for variable

demand as a fuzzy random variable. We considered a production inventory model for deteriorating

items with variable demand under the effect of inflation and shortages under fuzziness. The

deterioration rate is represented by a two-parameter Weibull distribution. By the centroid method of

defuzzification, the proposed model develops for minimizing cost function in the fuzzy sense. The

model is illustrated with numerical examples and sensitivity analyses of the optimal solution are

performed with respect to different parameters.

Initial basic feasible solution (IBFS) to a transportation problem (TP) plays an important role in

obtaining a minimal total transportation cost solution to the problem by a method in lesser number of

iterations. A good number of methods are available in the literature to find an IBFS. But IBFS varies

for different solution procedure and also for different examples. Still there is no unique method that

will calculate the optimal solution of all TP. To find the better IBFS, it is necessary to solve the TP by

using different algorithms. Because of the intractability of carrying out vast time-consuming

computations in TP solution procedure without a soft computing program, thirteen methods are coded

in this paper, using Matlab. Twenty sample transportation problems of different sizes, selected at

random from some reputed peer reviewed journal are solved to verify the code. Identical results with

the manual solution prove the correctness of our code.

In this paper, a solution procedure has been presented for the problem, which arose in MMUM

unbalanced transportation problem solution method. Usually, dummy warehouse or plant is used to

solve unbalanced transportation problem. Moreover surplus supply is to allocate in the dummy

warehouses and extra demand is taken as the supply available at the dummy plants with zero

transportation cost. But contradiction occurs here, as replacement without any transportation cost.

MMUM is a new solution procedure, presented to solve this contradiction. But in this procedure, a

problem has been arisen as the difference of supply and demand sometimes is a prime number. Here

in, we introduced a notation to take out the prime number at the range of nonprime. Illustrated result

shows that the problem has been solved efficiently.

In this paper, magnetohydrodynamic convection is analyzed numerically for a square enclosure filled

with Fe3O4–water ferrofluid. A time-dependent exponential thermal boundary condition is applied at

the bottom wall of the cavity. The ferrofluid is modeled as a single phase fluid. Maxwell-Garnet

model is used for modeling the effective thermal conductivity and viscosity of the ferrofluid. The

Galerkin-weighted residuals method of finite-element analysis is adopted for the numerical solutions.

The solid volume fraction, ? is varied from 2.5 to 10% and the Hartmann number Ha from 0 to 20.

Investigations are carried out for Rayleigh number Ra =104 and 105 over dimensionless times

?=0.01–1.0. The present study indicates that Ra, Ha and ? have a significant effect on heat transfer. At

? =1, if Ra=104, a higher solid volume fraction maximizes heat transfer whereas at Ra=10^5, a lower

solid volume fraction maximizes heat transfer. Moreover, incrementing Ha diminishes heat transfer at

Ra=10^4 whereas an optimum value of Ha=10 maximizes heat transfer for Ra=10^5. The exponential

thermal boundary conditions have a certain importance on heat transfer. The present results provide

necessary information for further investigation of heat transfer in its different applications.

Mollah Mesbahuddin Ahmed, Aminur Rahman Khan, and Md. Sharif Uddin



Transportation problems can be solved by general simplex method but it involves time-consuming

computations. There are specialized algorithms for transportation problems those are more efficient

than the simplex method. In the solution procedure of these specialized algorithms, an initial basic

feasible solution is always required to obtain the optimal solution. In this research, we evaluate the

performance of various methods for finding an initial basic feasible solution and observed that this

performance is inconsistent.

Md. Mossabber Chowdhury, Md. Moyazzem Hossain, and Ajit Kumar Mazumdar



Forecasting is the process of making predictions of the future based on past and present data. It is

highly used in econometric as well as time series analysis. There are different types of models which

are used in forecasting purpose. However, it is necessary first to identify the most suitable model. If a

time series exhibits long memory property, ARIMA model may not be reliable for forecasting. In that

case, ARFIMA model may be performing better. This paper therefore, focused on comparing the

forecast performance of ARIMA and ARFIMA model. The comparison is model on the basis of

model selection criteria like ME, RMSE, MAE, MPE, MAPE, MASE, AIC and BIC. The result

indicates that the ARFIMA model has found to be better than ARIMA model. Thus this paper

suggests using ARFIMA model instead of ARIMA model when the time series exhibits long memory

property.

Jahangirnagar University, Dhaka

In this paper, we consider finite difference method (FDM) for solving fourth order boundary value

problems. In order to verify the accuracy, we compare numerical solutions with the exact solutions.

The numerical solutions are in good agreement with the exact solutions. Numerical results show that

the proposed method is quite efficient and is practically well suited for solving these problems. The

approximate solutions converge to the exact solutions monotonically. In order to obtain greater

accuracy in the solutions, the step size needs to be very small. Finally we investigate and compute the

errors of the solutions for different step sizes. Several numerical examples are given to demonstrate

the reliability and efficiency of the proposed method.

Modeling the Effect of Adoptive Cell Transfer Therapy for the Treatment of Leukemia

Mst. Shanta Khatun, Md. Aminul Islam, and Md. Haider Ali Biswas

Khulna University


In this paper, we propose and analyze a mathematical model for leukemia, a cancer of the blood. We

model to study the spread of leukemia by considering the effect of adoptive cell transfer therapy. The

disease dynamics are given by a system of ordinary non-linear differential equations that describe the

interaction between susceptible blood cells, infected blood cells, cancer cells and immune cells. The

model is analyzed by using the stability theory of non-linear differential equations and numerical

simulation. A major goal of this work is to determine the spread of leukemia after applying the

adoptive cell transfer therapy. We have observed that the system is stable in the local and global sense

if antigenicity rate of immune cells is greater than a threshold value dependent on the density of

immune cells. Also, external infusion of immune cells by adoptive cell transfer therapy reduces the

concentration of cancer cells and infected cells in the blood. This implies that immune cells kill cancer

cells on being stimulated and as antigenicity rate increases rate of destruction of cancer cells also

increase leading to decrease in the concentration of cancer cells and infected cells in the body.

This work concerns with a nonlocal effect on a diffusive predator-prey model. The primary aim of this

work is to show the existence of PTW solution of the model in a one-parameter family of solutions.

Secondly, we calculate the wave stability and stability boundary in a two-dimensional parameter

plane. To understand the stability of the waves we calculate essential spectra of the PTWs. Finally, we

compare these results with the direct partial differential equations simulation in order to investigate

the mechanism of the irregular behavior of two species ecological systems.

Md. Muztaba Ahbab, Afia Farzana, and M. Osman Gani



The dynamic conjunction among predator and its prey is one of the extensive themes in ecology.The

reaction-diffusion models have been carrying indicatory histories via the theoretical ecology.We

consider a model for predator-prey dynamics and show the existence of the periodic traveling waves

numerically in a two-component reaction-diffusion system, where the fundamental reaction kineticsis

theformulation of classical Rosenzweig-MacArthur type. We investigate the existence of periodic

traveling waves for this model. We also investigate the stability in order to understand its stable and

unstable phenomena by calculating the essential spectra of the periodic traveling waves. It is observed

that periodic traveling wave losses stability via an Eckhaus bifurcation numerically. The irregular

pattern of predator and prey are found when the solutions cross the stability boundary. Keywords: Reaction-diffusion equation; predator-prey model; periodic traveling wave; stability; bifurcation

Bifurcation Analysis of Periodic Traveling Waves in a Two-Component Predator-Prey Model

Popy Das, Afia Farzana, and M. Osman Gani



Predator-prey models are arguably the building blocks of the ecosystem. In this work, we consider a

two-variable reaction-diffusion system of equations model to understand the mechanism of an

irregular behavior of predator and prey. We investigate the existence of periodic traveling waves for

the proposed model via the software package WAVETRAIN. By changing the half-saturation

constant ( ) in the hyperbolic functional response we study the numerical existence and stability of

the periodic traveling waves(wavetrains) in the model. A key feature of our work is to divide the

parameter plane into the stable and unstable region through a stability boundary of Eckhaus type. We

calculate the essential spectra of wavetrains to understand the stability of the waves. We also focus on

the bifurcation analysis of this model. The episodic act of predator and prey is traced when the

solutions cross the stability boundary.

Inequality Property of Interchange of Base and Index

Md. Maniruzzaman Miah


If a, bR and a b then and are also real numbers. Therefore, by Trichotomy law, either

or or But it is important to find out the values of a,b for which either of

the equality or inequalities holds. Ifa = 2 and b = 4 then And the Irrational number „e’ plays

an important role.

Theorem- 1: If e < a < bthen .

Proof : Let for n N and r < a

b = na + r …………………………… …………………………… (i)

Thus we have to proof that,

an a + r > (na +r )a …………………………… (ii)

For n = 1,

LHS of (ii) = aa+r = aa.ar =aa

and,

RHS of (ii)= (a +r )a = aa =aa

= aa

Since b>a>e, then lna> 1, and also lna> etc.

So,

LHS of (ii)> RHS of (ii).

Thus for n = 1, an a + r > (na +r )a is true.

Again, let (i) is true for n=m,

am a + r > (ma +r )a …………………………….(vi)

Then it has to proof that (v) is true for n =m+1,

a(m +1)a + r > { (m+1)a +r}a

am a +r+a> { (ma +a+r}a

am a +r.aa> (ma +r)a

Now, a<ma+r

< a


60

am a +r.aa> (ma +r)a

Therefore (vi) is true for all nN.

Hence, ab>b

a .

Theorem-2: If 0 < a < b<ethen .

Proof: Let, b = a + r, where r < a. …………………………………. (i)

Then, = aa+r

= aa. ar

= aa

= aa …………………………………. (ii)

And,

= (a +r )a

= aa

=aa

=aa

=aa

If 1 < a < e then

, ,

So,

Hence, from (ii) and (iii),

Theorem- 3: If a < bthen , if and only ifa = 2 and b = 4 .

Proof: Ifa = 2 and b = 4 , then .

conversely, if , then a < e and b > e.

Let is true for b = a + r when r < a

(a +r )a = aa =aa = aa

= aa+r = aa.ar =aa

Now,

gives,

which is not possible for r < a, because lna = 1 and (lna)2 = etc can‟t be happened

simultaneously.

Now, we are to proof that is NOT true for b = a + r when r > a

So, it is only possible that is true for b = a + r when r = a

i.e. b = 2a

Word Sense Disambiguation for Bangla Words Using Apriori Algorithm

Mohammad Shibli Kaysar, Mohammad Ibrahim Khan

Dept. of CSE, CUET


Morphological analysis is one of the most critical part of natural language processing. It becomes

more complex when the same word have several different meaning. In Bengali language it is a

frequent case. In such cases the meaning of the words are determined by other words used in the

sentence. Human have the intelligence to do the calculation but when the language is being processed

by machine, it would be difficult. in machine learning, there is an algorithm called apriori algorithm

which generates frequent item sets to recognize a pattern. In this paper we used apriori algorithm to

determine the meaning of a bengali word having multiple meaning. We found the proposed system

outperforms the lexicon based system.

Md. Mahfujur Rahman, and Md. Reazul Islam



It is an era of technology. Nowadays mobile is one of the most powerful technology in the new world

arena. There are a lot of mobile application which are providing increasingly richer functionalities. As

a result, mobile has a high computational complexity which results in high energy consumption of

mobile devices. The mobile applications like gaming, virtual reality, social media application and

showing videos, others applications are also evolved which require a lot of battery life and processing

capacity. So it creates a challenge to increase energy efficiency and performance enhancement as

those are resource-constrained devices. These challenges may be alleviated by computation offloading

in Mobile Cloud Computing which sending heavy computation to cloud and receiving the results from

this cloud. Offloading is one of the main features of MCC to improve the battery life for the mobile

devices and to increase the performance of applications. In this thesis, propose a new approach of

offloading algorithm that alleviates consumption of smartphone battery life which is based on time

complexity. The proposed algorithm solves the offloading optimization problem with much lower

complexity than the existing algorithm, which significantly reduces the execution time of mobile

Predicting the Rice Production of Bangladesh by Machine Learning Technique

Shohel Mahmud



Bangladesh is an agricultural country and its economic condition largely depends on agriculture. The

country produces much agricultural merchandise like rice, jute, wheat, onion, chilly, banana, garlic,

ginger, pulse and so on. However, rice (Oryza sativa) is produced most widely all over the country.

Moreover, United States Department of Agriculture (USDA), 2017 estimate that the rice production

of Bangladesh is 34.7 million metric tons for the period 2017-2018 and the position of Bangladesh is

after China, India, and Indonesia. In addition, Bangladesh produces three types of rice which are Aus,

Aman, and Boro. A huge portion of the population in Bangladesh immensely depend on rice as the

main food. So, this paper attempts to predict the rice production of Bangladesh with the help of

machine learning model like Artificial Neural Network (ANN). This paper considers a secondary data

set of yearly rice production in Bangladesh over the period 1971-1972 to 2014-2015. This paper

identifies the most suitable neural network model with architecture ANN based on model selection

criteria like MSE. Thus, this paper suggests ANN 3x3x2x1 model for envisaging the rice production

of Bangladesh.

Modelling for Forecasting the Rice Production of Jessore, Rangpur, Dinajpur, Kushtia and

Pabna Districts in Bangladesh

Md. Moyazzem Hossain, and Arafat Rahman



Bangladesh has an agrarian economy in which rice is the dominant crop. Rice is the staple food,

reflected in the high per capita rice consumption in this country. The nutritional demand of the

majority of people is met with rice. Over its long history, rice production of Bangladesh has gradually

changed in terms of yield potentials, cultivation techniques, and cropping patterns. Despite pressure

from over population, the country has reached self-sufficiency in rice production. Thus, this paper

attempts to identify the appropriate ARIMA (Autoregressive Integrated Moving Average) model that

is used to forecast the production of rice in Jessore, Rangpur, Dinajpur, Kushtia and Pabna districts. In

this paper, ARIMA (1,2,1), ARIMA (1,1,1), ARIMA (1,2,1), ARIMA (1,2,2), ARIMA (1,2,1) models

are found to be suitable for forecasting the rice production also the test result indicating that the

errors of the selected model are not auto-correlated as well as follows the normal distribution. Finally,

these models are used to forecast rice production of the selected districts for the upcoming 20 years

which help the decision makers to establish the rice production management.

Modeling of Mean Sea Level of Bay of Bengal: A Comparison between ARIMA and ANN

Md. Moyazzem Hossain, Shezan Ahmed, Md. Habibur Rahman



The Bay of Bengal is the largest bay in the world with waters flowing straight out of the Himalayas

through Bangladesh. Roughly triangular, it is bordered by Bangladesh to the North, Myanmar to the

East, Sri Lanka and India to the west. Sea level change is one of the many impacts of the recent trend

of changing climate (IPCC). A further rise in sea level is a threat to the existence of many people in

Bangladesh. If the sea level rises by 45 centimeters, scientists expect a permanent loss of up to 15,600

square kilometers of the land of Bangladesh. Moreover, indirect effects of the rising sea level will

increase the salt content of soils. In view of Bangladesh‟s already problematic food situation, the

expected decrease of rice production as well as several hundred tons of vegetables, lentils, onions and

other crops could be disastrous. Last but not least, valuable ecosystems would be lost. The

Sundarbans, huge mangroves swamps along the coasts that are part of the United Nations world

natural heritage, will be especially affected. They are the last retreat of the Bengal tiger. Thus this

paper attempt to identify the most suitable model for forecasting the mean sea level of Bay of Bengal.

Here, this paper forecast the future mean sea level using both ARIMA and ANN model and compare

the forecasting accuracy of these two models. On the basis of model selection criteria considered in

this study, we find that the ANN model performs better than ARIMA model. So, in order to forecast

the mean sea level of Bay of Bengal, this study suggests using ANN model instead of ARIMA model.

On the Marginal Likelihood Method of Estimating and Testing Parameters of Remainder

Disturbances Follow a Specified AR(p) or MA(q) Process

Lakshmi Rani Kundu

IQAC, Jahangirnagar University

Dr. Ajit Kumar Majumder



The usual reason for including a disturbance term in the regression model is to account for the effects

of omitted or unobservable regressors, errors in the measurement of the dependent variables and

functional approximations. Some of these effects are typically autocorrelated over time. Usually

AR(4) or MA(4) arise in quarterly data. For the error components model with the remainder error

following an AR (p) or MA (q) process, the estimation method becomes more complicated in the

presence of nuisance parameters along with sign of the parameters. In order to solve the above

problems, we use marginal likelihood estimation method that can be used to test the parameters of an

error component model.

Integrating Overweight-obesity and Reproductive Factors of Married Women in Bangladesh

Md. Meshbahur Rahman, Zaki Farhana, Tania Akhter Tani, Mohammad Ohid Ullah



Overweight or Obesity has become a burning question because it is associated with various health

complications. It is increasing day by day all over the world. In Bangladesh, it is higher among

Bangladeshi women than men. Therefore, we aim to integrate the overweight-obesity factors with the

reproductive factors among the married women in Bangladesh aged 15-49 years. Methods: To

conduct this study we used a secondary cross-sectional data on a wide range of indicators relating to

population, health, and nutrition from Bangladesh Demographic and Health Survey (BDHS) 2014. In

this study, we analyzed married women‟s nutrition-related data using logistic regression model and

multi-factor analysis (MFA). Results: The data included 17,863 married women of various ages. Of

17863 women, about 18.8% were overweight and 4.3% were obese. Women of Khulna, Chittagong,

and Dhaka division had a higher risk of being overweight or obese compared to the women of the

Barisal division. The richest women were 6.233 times (95 % CI: 4.004-9.720, p < 0.001) more likely

to be overweight or obese compared to poorest women. It was also found that the prevalence of

overweight or obesity was higher in urban (37.5%) women than rural women (19%). From the multi-

factor analysis, we found in overweight-obesity factors- Wealth Index, TV watching and current

occupation of women are positively associated with overweight or obesity. Integrating the factors of

overweight-obesity with reproductive groups, we found -Wealth index, Current occupational status

and TV Watching in the overweight-obesity group are positively associated with Educational status

and Breastfeeding of the reproductive group. Conclusions: Taken together, we can conclude that a

large number of married women were suffering from overweight-obesity problems. Therefore, special

health-related programs such as promoting the higher level of physical activities, ensuring nutritional

food policies and improving awareness through educational institutions should be provided

substantially for reducing the prevalence of overweight or obesity of married women in Bangladesh.

A Comparative Study among Poisson, Negative Binomial and Hermite Regression

Shohel Mahmud, Md. Moyazzem Hossain, and Karimuzzaman Sunny



Count data regression modelling techniques have become important tools in empirical studies and its

applicability grows day by day. In case of count data Standard regression analysis is inappropriate.

However, if certain assumptions are met, in general, the most common regression approach for

handling count data is probably Poisson regression approach. Real data, however, are often over- or

under-dispersed and, thus, not conducive to Poisson regression. In such situation, some other

regression approaches like negative Binomial, Hermite regression give a better result. So, in this

paper, a comparative study has been conducted to find out best regression model by using Akaike

information criterion (AIC).

Forecasting is a very challenging task in time series analysis. Risk and uncertainty are central to

forecasting and prediction; it is generally considered good practice to use the appropriate time series

model for the forecasting purpose. In this regard, Automatic Forecasting Analytics can be very useful

to evaluate the appropriate model if it performs well. We conduct Monte-Carlo Simulation to evaluate

the autoforecasted model and we observe that autoforecasting analytics does not provide the best

model. Our estimated models perform better than the models estimated by Autoforecasting Analytics.

The nonlinear propagation of intense electromagnetic waves and modulational instability in a

rotational ultra-relativistic magnetized electron-positron pair plasma of a pulsar magnetosphere have

been theoretically and numerically investigated by deriving as well as solving nonlinear Schrödinger

equation. In order to study the nonlinear wave propagation in the rotational astrophysical objects, one

must be considered Maxwell's equation in the rotational frame of reference (Non-inertial frame) along

with other equations (continuity, momentum, and heat conductivity equation) to conserve one of the

basic properties of light i.e. light passes in a straight line. It has found that the electromagnetic waves

propagation in such a plasma system is modulationally unstable, and the model leads to

electromagnetic solitons under the condition of extreme rotation. It is noticed that high amplitude

solitons are produced in the pulsar magnetosphere. It is also found that the soliton‟s amplitude

increased rapidly while their widths become narrower with the increased of pulsar rotations that are

related to the pulsar radiation (electromagnetic radiation). The findings of this investigation may be

used in understanding the nonlinear electromagnetic waves phenomena in rotating astrophysical

plasmas and laboratory plasmas.

Nuclear medicine is the use of radionuclides in medicine for diagnosis and treatment of diseases. In

nuclear medicine imaging small amounts of radiotracers are injected into the bloodstream, inhaled or

swallowed. It has effect on the body after administrating radionuclide into the body. The purpose of

the study is to determine the effective dose of thyroid gland in nuclear diagnostic during thyroid scan.

The study was performed on 100 patients presented for thyroid scan in Institute of Nuclear Medicine

and Allied Sciences (INMAS), Dhaka Medical College Campus, Dhaka, Bangladesh. The organ dose

and effective dose were calculated after administration of 99mTc pertechnetate using Medical Internal

Radiation Dosimetry (MIRD) manual calculation and MIRD software. The uptake of radionuclide in

thyroid was considered 4% for the dose calculation. The mean age of male, female, children (girl) and

children (boy) were 40.92, 39.7, 14.67 and 4.5 years respectively. The mean effective dose of male,

female, children (girl) and children (boy) calculated using MIRD manual calculation were

0.983±0.136, 0.936±0.0996, 0.92±0.208 and 0.476 mSv respectively. The mean effective dose of

male, female, children (girl) and children (boy) calculated using MIRD software were 0.711±0.098,

0.824±0.088, 1.105±0.250 and 2.37 mSv respectively. Two different options was used for calculating

by software in respect of adult males and female. This can be the reason for the difference of dose to

male and female. The age and weight of children (girl) patients were 13, 14, 17 years and 38, 44, 44

68

kg respectively but during calculation by software, 15 years (57 kg) option was used for them and the

age and weight of children (boy) was 4.5 years and 14 kg respectively but the dose of the patient was

calculated by using 5 years (19kg) option. Because in software there was no option for 13,14, 17 and

4.5 years. This can be the reason of high dose to them compared to manual calculation. The obtained

effective doses of patients during the imaging procedure were in acceptable limit. The dose was very

little to induce cancer in thyroid gland.

Cupric oxide thin films were prepared by doctor blade method on microscopic glass substrate. The

appearance of the films were generally uniform and brownish black in color. The gamma radiation

dose from Co60 source given to the sample having dose of 20KGy, 40KGY, 60KGy, 80KGy and

100KGy. The optical, structural and morphological properties of as deposited films have been

characterized by ultraviolet-visible spectroscopy, X-ray diffraction (XRD) and Scanning Electron

Microscopy (SEM) respectively. The effect of gamma radiation on the structural, optical and

morphological properties was studied. The XRD pattern showed that the thin films produced were

found to be polycrystalline with monoclinic structure. The preferred directions of crystal growth

appeared in the CuO thin films were correspond to the reflections from the (110), (?111), (111) and

(?202) plane and the dominant peak observed at the plane (?111) at an angle of 35.370. Cupric oxide

is intrinsically p-type semiconductor. The optical parameters of prepared films as transmittance,

absorbance, optical band gap, absorption co-efficient, skin depth and extinction co-efficient were

found to be influenced by varying radiation doses. The effect of gamma radiation on CuO thin films

were observed. The transmittance of the films were decreased and the absorbance of the films were

increased with increasing radiation doses. It has a clear significance on the band gap measurement

before and after radiation effect within these sample. The optical band gap decreases with increasing

radiation doses both for direct and indirect transitions. According to results, the film affected by

highest radiation dose 100KGy obtains the better optical properties. The SEM images revealed that

the surface morphology changed with changing radiation doses. It also confirmed the monoclinic

crystal structure with polycrystalline nature of thin films. The Cu and O concentrations in the CuO

films were determined from Energy Dispersive X-ray (EDX) study. Finally the obtained results

revealed that the structures and properties of the films were greatly affected by gamma radiation

doses, and it made the cupric oxide thin film suitable for various applications.

One of the major ecological problems we are confronting today is the plastic waste problem. The huge

amount of plastic generation and utilization in each section of our life has expanded the plastic waste

in immense scale. This is the reason why the natural resources have become a field of interest for the

researchers. Sawdust fiber reinforced Acrylonitrile Butadiene Styrene (ABS) biodegradable polymer

composite was prepared by using a hot press machine at 180? and 50KN. Five different weight

percentages (0wt%, 5wt%, 10wt%, 15wt%, 20wt%) of fiber content were incorporated in sawdust-

ABS composites. The maximum bulk density was found to be 1.035 gm/cm3 for 20wt% composite.

Percentage of water absorption increased with the increase of fiber content and soaking time. The

tensile strength decreased with the increase of the fiber content. For 5wt% composite the elongation at

break was maximum and Young‟s modulus increased with the addition of fiber content. Leeb‟s

rebound hardness decreased with the increase of fiber content which means that the prepared

composites were not as stiff as the pure ABS polymer. Fourier Transform Infrared (FTIR) spectra

were also observed to find out whether any new bond was formed. A C?C bond was found for 20wt%

composite at 2363 cm-1 and the C-H bond for 0wt% composite at 911 cm-1 was not present in all

other composites.

An Arduino (new generation high performance microcontroller) based radiation survey meter has

been designed and developed using two scintillation detectors. A square wave pulse train of 16 KHz

frequency was generated from the Arduino to produce high voltage. This regulated high voltage

(1200V) power supply was used to activate the scintillation detector. Two pre-amplifier circuits and

two amplifier circuit were designed to amplify the small output signal of the detector. A summing

circuit was used to add two individual amplified signals to provide total pulse to the microcontroller.

The Arduino microcontroller senses and processes the pulse and show the result through a liquid

crystal display. The programming language C has been developed for pulse generation and to control

the function of Arduino. The performance of the developed system was tested and compared with

microcontroller based radiation survey meter having one scintillation detector and with CANBERRA

NIM counter. The performance of the designed system was quite satisfactory.

Nonlinear propagation of dust-acoustic solitary waves (DASWs) are studied in a self-gravitating dusty

plasma containing inertial dust of opposite polarity, trapped ions, and Boltzmann electrons. The

reductive perturbation technique is employed to derive standard Kortweg-de Vries (KdV) and

modifed Kortweg-de Vries (mKdV) equations and their solitary wave solutions. The parametric

regimes for the existence of the DA solitary structures (associated with electrostatic and gravitational

potentials) and their basic properties (viz., polarity, amplitude, width, and speed) are found to be

significantly modified by the combined effects of positively as well as negatively charged dust

component, self-gravitational field, and trapped ions. The present investigation can be very effective

for understanding and studying the basic features of DA wave in different space dusty plasma

environments are briefly discussed.

Polymer based product has been playing a vital role in our everyday life and along with the increasing

usage of plastics there is an increasing threat to the environment due to its non-biodegradable nature

and sometimes they are impractical to recycle due to high cost. Plastic based waste disposal is another

matter of great concern for every country. These issues concerning ecological effect and also the

potential diminution of petrochemical deposits has led to the development of alternative natural and

renewable resources. Natural fiber reinforced plastics material has become very attracting alternatives

because of their low cost, light-weight, enhanced mechanical properties and are free from health

hazard. This composites are biodegradable and environmental friendly as it has little contribution in

greenhouse gas emission. For the past decades lots of research work have been conducted to enhance

the mechanical properties of natural fiber reinforced composite for their various potential applications.

In this research work, we prepared bamboo fiber (BF) reinforced acrylonitrile butadiene styrene

(ABS) composite by varying fiber content in order to improve mechanical properties of this natural

fiber reinforced polymer composite. The BF-ABS composites were fabricated by hot press molding at

180? and 50 KN, by varying bamboo fiber content i.e., 5, 10 and 15 wt.% and the physical,

mechanical and bonding properties were studied by universal testing machine (UTM), rebound

hardness tester and FTIR spectroscopy. The bulk density of composite decrease with the addition of

bamboo fiber and it is lowest for 10 wt% composite. With the increase of fiber content the water

absorption increases and 15 wt.% BF-ABS composite absorb more water. The tensile strength of BF-

ABS composites decrease with the addition of bamboo fiber. But for 10 and 15 wt.% it increases

71

gradually. The elongation at break increases with the addition of 5 and 10 wt.% bamboo fiber to ABS

polymer however it decreases for 15 wt.% BF-ABS composite. The leeb rebound hardness increases

for 5 wt.% BF-ABS composite but it decreases gradually for further fiber loading. The Fourier

transform infrared (FTIR) spectra reveals that for 5 wt.% fiber addition a new N-H bond appears and

for 15 wt.% fiber loading another new bond O-H appears.

Jahangirnagar University, located in Bangladesh, has a rich biodiversity with diverse plant kingdom.

Environmentally benign dyes are one of the most important product of nature. Recently there has been

an increasing demand for use of such natural dyes as the environmental issues with synthetic dyes are

highly regulated by more and more countries due to their adverse effect on environment and other

health hazard related to their increasing commercial uses. With more than hundreds of natural dye

resources from nature at our disposal, five flower plants namely Portulaca grandiflora (Time flower),

Rosa ards rovar (Red rose), Celosia argentea var. cristia (Plumed cockscomb), Pereskia bleo (Desert

rose) and Alternanthera ficoidea (Border plant) were chosen as common dye sources for the present

research work. In this paper we report, the extraction process for five different collected flower plants

utilizing different dye extraction methods to decide the best dye removal process. Also a comparative

study was performed for different solvents, ethanol and water, as used to extract the natural dyes. The

analytical studies, for example, UV spectroscopy, column chromatography, vacuum evaporation for

isolating dye from their solution and X-Ray Diffractions were performed on the dye extracts. The

UV-vis spectra of the pigments in the flower extracts were found to have broad absorption peaks from

400 nm to 800 nm. The extracted dyes were investigated by Fourier transform infrared spectroscopy.

Investigation of different extraction techniques for natural dyes demonstrated that ethanol produced a

better extraction than water. Dye extraction yield rate extended from 1.08 % to 6.7% which was

determined by the plant removed and solubility of pigments extracted by two solvents. Column

chromatography was utilized as a dye purification method and also used for the study of the aging

impact for 60 days at room temperature (25° C) and at 60° C.

Almost every year, tropical cyclone forms over the Bay of Bengal in pre-monsoon and post-monsoon

which strike Bangladesh coast and the east coast of India. The genesis, propagation, and intensity as

well as landfall are very important for a tropical cyclone. Till today the full thermodynamic features

of a cyclone is not solved. In this work, an attempt has been made to simulate the track and landfall of

cyclonic disturbances over the Bay of Bengal by using Weather Research and Forecasting (WRF)

model. The WRF model (version 3.8) was run in a single domain of 20 km horizontal resolution.The

model was run using WRF Single-Moment 3-class microphysics scheme, Kain- Fritsch (new Eta)

cumulus physics scheme, Yonsei University planetary boundary layer scheme, Revised MM5 surface

layer physics scheme, Rapid Radiative Transfer Model (RRTM) for long-wave and Dudhia scheme

for short-wave scheme. The model was run for 24-h, 48-h, 72-h and 96-h using the National Centre

for Environmental Prediction (NCEP) high-resolution Global Final (FNL) Analysis 6-hourly data

using initial and lateral boundary conditions. The model performance is evaluated analyzing Mean

Sea Level Pressure (MSLP), Wind Pattern, Relative Humidity, Relative Vorticity, Vertical Wind

Shear, Temperature, Vertical distribution of Velocity components and Rainfall distribution. The

model successfully captured the low pressure system, initial condition, propagation, landfall time and

location reasonably well. Even in 96-h prediction, model has successfullysimulated the landfall. The

model simulated track and landfall are sensibly compared with the data observed by BMD. The model

simulated landfall position error are found 53 km, 129 km, 119km and 23 km for 96-h, 72-h, 48-h and

24-h model run respectively. The model simulated landfall time errors are found 02E, 06D, 02E and

same for 96-h, 72-h, 48-h and 24-h model run respectively (E indicates Earlier and D indicates

Delay). The minimum time and position error is found in 24-hrs simulation. The model simulated

rainfall of some stations of BMD is also compared with the observed rainfall. The spatial distribution

is captured by the model well but the computational station rainfall is found less than that of observed

rainfall.

In this work, variability of rainfall of pre-monsoon months has been analyzed. For this monthly

rainfall of March, April and May as well as pre-monsoon season for the period of 1981-2016 of eight

divisional locations of Dhaka, Chittagong, Rajshahi, Khulna, Barisal, Rangpur, Mymensingh and

Sylhet have been analyzed. It is found that the variability measured through STD is very high at all of

the selected locations and the trends of pre-monsoon rainfalls are mostly negative. The trends of pre-

monsoon rainfall at Dhaka, Chittagong, Rajshahi, Khulna, Barisal, Rangpur, Mymensingh and Sylhet

are -9.13, -5.73, +0.05, -4.58, -3.57, -0.34, -5.13, -0.79 mm/year respectively. To know the

atmospheric condition during the days of heavy rainfall associated with the STS different stability

indices of seven selected dates of 08 April 2012, 09 April 2012, 06 May 2013, 19 April 2017, 22

April 2017, 23 April 2017 and 24 April 2017 during 2012-2016 were calculated. The lowest

magnitudes of SI, LI and KI were -8.1, -10.2, and 23.7 respectively. The highest value of CAPE was

3631.8 Jkg-1. Signatures of heavy rainfalls were mostly concentrated over central and adjoining

southeastern parts of Bangladesh. The highest amounts of rainfalls of 129, 122 and 112 mm are found

to record at Hatiya, Kutubdia and Chittagong respectively 06 May 2013. Two significant rainfall

events occurred in Bangladesh during of 06 May 2013 and 22 April 2017 are simulated using WRF

Model with the aim to understand the inherent features of pre-monsoon convective system.

Simulation reveals that evolution and persistence of high temperature at 2m, high relative humidity

(RH), strong convergence, high CAPE and vorticity and their vertical extension upto mid-

tropospheric level are the main cause and features for the heavy rainfall associated with STS in

Bangladesh. Location specific simulated rainfalls (based on BMD rain gauge locations) were

compared with observed rainfall to know the performance of the model. Model rainfalls were found

highly co-related with the observation but station average model rainfalls were higher than

observations. Locations of the simulated heavy rainfall zone were found very near to observations.

Simulated results can there be used to identify the pre-monsoon convective system and estimation of

rainfall amount associated with STS.

Nano sized Zinc Oxide rod was synthesized onto glass substrate via simple sol-gel technique. The

structural, morphological, chemical, elemental and optical properties of as synthesized of ZnO thin

films were studied using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier

transform infrared (FTIR) spectroscopy Energy dispersive X-ray (EDX) spectroscope and ultraviolet–

visible (Uv-Vis) spectroscopy, respectively. The hexagonal wurtzite structure of the ZnO nano-rod

was confirmed by XRD analysis. The XRD and SEM analysis also confirmed the nano-structure of

the as prepared ZnO thin films. FTIR spectra showed the chemical composition mainly functional

groups present in the ZnO thin films. The EDS analysis ensured the the presence of zinc and oxygen

elements in the films. Several optical constants, such as optical band gap, Urbach energy, steepness

parameter, skin depth, etc were estimated with help of Uv-Vis spectra.

Mg doped ZnO (MZO) thin films were prepared on glass substrates using sol-gel spin coating

technique. The prepared MZO thin films were irradiated with gamma radiations, emitted from a

cobalt (60Co) source, ranging from 0 to 100 KGy. The optical, structural and morphological

properties of the irradiated films were analyzed by UV-Vis spectroscopy, X-ray diffraction (XRD)

and scanning electron microscopy (SEM). The absorption coefficient, skin depth and extinction

coefficient of both the radiated and un-radiated MZO thin films were calculated and compared. The

optical band gaps of the films were determined; the band gap was decreased with increasing gamma

radiation dose. The hexagonal wurtzite structure was observed in all the prepared MZO thin films

with a preferred orientation along the (002) plane. The gran size, dislocation density, interplanar

distance, lattice constant, micro strain and lattice strain of the films were calculated, and their

variations with increasing gamma radiation were studied. The surface roughness as well as the

crystalline nature of the films were changed with the provided gamma radiation doses. The presence

of O, Mg and Zn within the MZO thin films were confirmed through energy dispersive X-ray (EDX)

studies. The controllable optical and structural properties of Mg doped ZnO (MZO) thin films are

very important for their applications in solid state and optoelectronic devices.

Eigenmode analysis of spherical brain activity via neural field theory

Kamrun Nahar Mukta, James Normand MacLaurin, and Peter Robinson


Corticothalamic neural field theory (NFT) has successfully explained a wide variety of phenomena,

ranging from EEG spectra and evoked potentials to nonlinear phenomena such as seizures and

Parkinsonian oscillations. NFT has also been used to understand brain connectivities and its

eigenmodes have been employed to solve the inverse problem of determining brain structure from

functional connectivity. Most recently, its unihemisphericeigenmodes have been shown to be

remarkably similar to spherical harmonics in structure. They are also the building blocks for

bihemispheric modes, whose structure and symmetry properties explain many features of resting state

and task-related activity. This eigenmode expansion is of use because it helps us understand the

dynamics of the brain‟s activity in terms of its natural modes. Here, corticothalamic NFT is analyzed

on a sphere and used to derive the transfer function, the power spectrum, the correlation function, and

the cross spectrum in terms of spherical harmonics. The results are analyzed and compared with

planar NFT in both finite and infinite geometries. The results of spherical and finite-planar geometries

converge to the infinite-planar geometry in the limit of large brain size. The main effects of the

spherical modal structure are explored, particularly to understand the number of modes that contribute

significantly to these observable quantities and the effects of the finite spatial extent of the cortex.

Key results are that when we truncate the modal series it is found that, for physiology plausible

parameters, only the lowest few spatial eigenmodes are needed for an accurate representation of

macroscopic brain activity. Cortical modal effects can lead to a double alpha peak structure in the

power spectrum, although the main determinant of the alpha peak is corticothalamic feedback. In the

spherical geometry, the coherence function between points decays monotonically as their separation

increases at a fixed frequency, but persists further at resonant frequencies. The correlation between

two points is found to be positive, regardless of the time lag and spatial separation, but decays

monotonically as the separation increases at fixed time lag. At fixed distance the correlation has peaks

at multiples of the period of the dominant frequency of system activity. This analysis of

physiologically-based corticothalamic NFT in a spherical geometry will enable more realistic

modeling and analysis of experimental brain signals in future.
