“Video Shot Detection using Saliency Measure” - Amuda J., Radha D. and Naresh

Kumar; International Journal of Computer Application (IJCA), May 2012.

Video shot boundary is an early stage of content based video analysis and is

fundamental to any kind of video application. The increased availability and usage of

online digital video has created a need for automated video content analysis techniques.

Major bottle neck that limits a wider use of digital video is the ability of quickly finding

desired information from a huge database. Manual indexing and annotating the video

material are both computationally expensive and time consuming. In this paper, we

design a novel approach for shot boundary detection using visual attention model by

comparing the saliency measures. The approach is robust to a wide range of digital effects

with low computational complexity.

“Estimating Trust Value for Cloud Service Providers using Fuzzy Logic” - Supriya M.,

Application (IJCA), June 2012.

Cloud computing has garnered popular support in a relatively short span of time. It

is a new method of delivering the distributed resources over internet. It reduces capital

expenditure as well as operational expenditure. The number of cloud service providers

(CSPs) who provide computing as a utility has increased exponentially in the past few

years, providing more options for the customers to choose from. In this paper a model for

Trust Management based on Fuzzy Logic has been developed, which can help consumers

make an informed choice towards selecting the appropriate CSP as per their requirement.

“Interoperability between Wireless Networks Using FPGA Based Advanced Gateway” -

Mridula K.M. and Vinodhini M.; International Forum of Researchers, Students and

Academicians’ (IFRSA’s), International Journal of Mobile and Adhoc Network (IJMAN),

June 2012.

In a communication network, a network node equipped for interoperability with

another network can use different protocols and frame formats. So there is a need for

protocol conversion to provide a match between the source and destination networks. To

satisfy the requirements of protocol conversion and thus to provide interoperability,

gateways are used. In this paper, we design and implement an advanced FPGA based

gateway architecture that allows multiple data transmission to communicate between

different wireless networks like Wi-Fi, Bluetooth and ZigBee. The gateway architecture is

named - Heterogeneous Gateway as it provides multiple interfaces to three different

wireless networks for supporting various applications. We first analyse the frame formats

of these three networks and their implementation principles, then illustrate the key

modules by using FPGA, finally show the simulation results on the reliability and accuracy

of the FPGA.

“Design of a Control Logic in a Dynamic Reconfigurable System” - Prasannakumar A.

and N.V.S. Murthy; IOSR Journal of Electronics and Communication Engineering

(IOSRJECE), June 2012.

In this paper, we propose architecture for controlling Dynamic Reconfigurable

systems. The processor instructions when compiled one by one produces very high delay

overhead. If these instructions are converted into a combinational logic then the overhead

can be reduced thereby making the system an efficient one. This paper presents a method

for creating the control logic necessary for performing operations on instructions. The

proposed design is simulated using Modelsim 10.0c. The area and power constraints are

evaluated using Synopsys Design Compiler.

“Design, Implementation and Performance Analysis of an Integrated Vedic Multiplier

Architecture” - Ramachandran S. and Kirti S. Pande; International Journal of

Computational Engineering Research (IJCER), June 2012.

Fundamental and the core of all the Digital Signal Processors (DSPs) are its

multipliers and speed of the DSPs is mainly determined by the speed of its multipliers.

Multiplication is the most fundamental operation with intensive arithmetic computations.

Two important parameters associated with multiplication algorithms performed in DSP

applications are latency and throughput. Latency is the “real delay of computing a

function”. Throughput is a measure of “how many computations can be performed in a

given period of time”. The execution time of most DSP algorithms is dependent on its

multipliers, and hence need for high speed multiplier arises.

Urdhva tiryakbhyam sutra performs faster for small inputs and Nikhilam sutra for

larger inputs. Here a novel Integrated Vedic multiplier architecture, which by itself selects

the appropriate multiplication sutra based on the inputs, is proposed. So depending on

inputs, whichever sutra is faster, that sutra is selected by the proposed integrated Vedic

multiplier architecture. In the simulation results, it can be seen that Urdhva performs

faster for small inputs, but Nikhilam performs better for large inputs (more than twice as

much for 64 bit multiplicands).

“Design and Analysis of 16 Bit Reversible ALU” - Lekshmi Viswanath and Ponni M.;

IOSR Journal of Computer Engineering (IOSRJCE), June 2012.

Reversible or information-lossless circuits have applications in digital signal

processing, communication, computer graphics and cryptography. Reversibility plays an

important role when energy efficient computations are considered. Reversible logic is

used to reduce the power dissipation that occurs in classical circuits by preventing the

loss of information. This paper proposes a reversible design of a 16 bit ALU. This ALU

consists of eight operations, three arithmetic and five logical operations. The arithmetic

operations include addition, subtraction, multiplication and the logical operations include

NAND, AND, OR, NOT and XOR. All the modules are being designed using the basic

reversible gates. The power and delay analysis of the various sub modules is performed.

“Oscillation Test Methodology for Built-In Analog Circuits” - Sankari M.S. and Satish

Kumar; International Journal of Computational Engineering Research (IJCER), June

2012.

This article aims to describe the fundamentals of analog and digital testing methods

to analyze the difficulties of analog testing and to develop an approach to test the analog

components in a mixed signal circuit environment. Oscillation based, built-in self-test

methodology for testing analog components in mixed-signal circuits, in particular, is

discussed. A major advantage of the OBIST method is that it does not require any complex

response analyzers and test vector generators which are costly; Furthermore, since the

oscillation frequency is considered to be digital, it can be easily interfaced to test

techniques dedicated to the digital part of the circuit under test (CUT). OBIST techniques

show promise in detecting faults in mixed signal circuits and requires little modification of

the CUT to improve the fault coverage. Extensive simulation results on some sample analog

benchmark circuits are described in Spice format.

“Assessment of Glass/Drumstick Fruit Fiber (Moringa Oleifera)” - B.H. Nanjunda Reddy;

International Journal of Polymeric Materials, June 2012.

Glass fibers=drumstick fruit fibers (GF=DFF) reinforced with epoxy hybrid composites

were fabricated using the rule of hybrid mixtures. Properties like impact strength, frictional

coefficient, dielectric strength, and chemical resistance were studied. Treated and untreated

DFF were reinforced along with GF to assess two different epoxy hybrid composites. The

effect of alkali treatment on the above-mentioned properties was also studied. It is observed

that the impact strength and frictional coefficient properties of the hybrid composites

increased with increase in glass fiber content. Performance elevated for alkali-treated DFF

hybrid composites when compared to untreated DFFChemical. Resistance significantly

increased for all chemicals except carbon tetrachloride due to attack of chloride

hydrocarbons on the cross-linking of the epoxy. Elimination of amorphous hemi-cellulose by

alkali treatment improved the properties. Fiber-polymer interactions were studied by

scanning electron microscopy on the cross-sections of fractured surfaces.

“Investigations on Micro-Blast Wave Assisted Metal Foil Forming for Biomedical

Applications” - Nagaraja S.R. and Rakesh S.G.; International Journal of Mechanical

Sciences, April 2012.

The deformation dynamics of metal foils (0.25 mm thick) subjected to micro-blast

wave are presented in this paper. The energy of micro-blast wave emanating from the open

end of a polymer tube is used to deliver micro-particles for bio-medical applications. In

these experiments, metal foils are used to transfer the energy of the micro-blast wave to

the micro-particles. Using cubic root scaling law the over pressure of the blast wave at the

open end of the polymer tube is estimated and using this peak plate over pressure is

estimated. The finite element analysis is used to estimate the velocity profile of the

deforming metal foils. The finite element analysis results are compared with experimental

results for the maximum deformation and deformed shape. Based on the deformation

velocity, metal foil to be used for experiments is selected. Among the materials

investigated, 0.1mm thick brass foil which has the maximum velocity of 205m/s is used in

the experiments. It is found from finite element analysis that the particles deposited within

a radius of 0.5mm will leave the foil with nearly equal velocity (error < 5%). The spray cone

angle which is the angle of deviation of the path of particles from the axis of the polymer

tube is also estimated and found to be less than 7° up to a radius of 0.75mm. Illustrative

experiments are carried out to deliver microparticles (0.7mm diameter tungsten) into

plant tissues. Particle penetration depth up to 460mm was achieved in ground tissue of

potato tuber.

oriented cracks in complex shell type structures is presented. A fine mesh of singular

isoparametric triangular shell element (STRIA6) with user specified number NS from one

crack face to another and size Da is created around each crack-tip. The rest of the domain is

discretized using a compatible mesh of regular quadratic isoparametric triangular shell

element (TRIA6) and quadratic isoparametric quadrilateral shell element (QUAD8). A new

post processing subprogram 3MBSIF is presented to compute the Stress Intensity Factors

Posteriori. The proposed Finite Element Model implemented using ABAQUS, a unified FEA

software, and the new post processing subprogram 3MBSIF are validated using

benchmarks, a set of standard test problems with known target solutions. Selected results

of a parametric study are presented for arbitrarily oriented cracks of increasing lengths in

Caring and Sharing

"The heart sends blood to every cell of the body,

and in this way the cells are nourished. The same

blood then flows back to the heart. If the flow is

obstructed, the person will die. We need to learn

this process of give and take from the heart. For

the benefit of others, and also for ourselves, we

should have the attitude of caring and sharing.

We are all links in the chain of life. If one link is

weakened, it will affect the strength of the whole

chain."
