Higher Education Consultant, Jordan

Abstract

Technology has often been cited as the major driving force behindinnovation in higher education and for educational reform in a variety ofcontexts. Modern digital technologies such as computers, telecommuni-cations, and networks are reshaping and eventually revolutionizing bothour society and our social and educational institutions. A new society,the knowledge society is thus arising, the elements of which coexistingwith the constitutive elements of the industrial and postindustrial so-ciety. The most obvious aspect of the new society is the speed of use,application and dissemination of the communication and informationtechnologies, which puts in the shade the fact that there occurs a majortransformation of concepts, structures and institutions specific to theprevious society. Within the technological context, electrical engineersplay a significant role. They develop new design, manufacturing pro-cesses and products. They advance and manage communication, trans-portation, health care devices and energy systems. They address theenvironmental issues and the make technology work. The electrical en-gineering activities generate a remarkable potential for the private andthe public sectors to develop the national wealth and strength. Thechairman of the American National Academy of Engineering noted that“the nation the best engineering talent is in possession of the core ingre-dient of comparative economic and industrial advantage”.

Abstract

Surface and bulk acoustic wave (SAW and BAW) devices are suit-able as passive wireless sensor elements, called SAW transponders orBAW sensors, for measuring physical quantities e.g. temperature, pres-sure or specific bio molecules even in liquids. But the sensitivity ofthe resonance frequency in liquids depends on the polarization of theacoustic wave and therefore shear wave polarizes surface or bulk acous-tic waves are respectively needed. In the recent years different kindsof approaches of SAW transponders for sensor applications were pub-lished mainly based on piezoelectric materials designed for filter applica-tions with longitudinal wave polarizations e.g. Rayleigh waves for SAWtransponders or longitudinal waves for BAW sensors. A new approach ispresented designing adapted piezoelectric materials with Metal-Organic-Vapor-Phase-Epitaxy (MOVPE) especially for sensor application andtherefore with shear wave polarization of the acoustic waves in this work.

Abstract

An adaptive nonlinear sliding mode controller combined with a fieldorientation scheme has been developed for the control of induction mo-tor to achieve rotor angular speed and rotor flux amplitude trackingobjectives. The inputs to the controller are the reference speed, the ref-erence flux, the measured stator currents, the measured rotor speed, theestimated rotor flux, and estimates of the varying non measurable pa-rameters. The unknown load torque and the rotor resistance which mayvary during operation. The controller outputs are the reference statorvoltages. An accurate knowledge of the rotor flux, the load torque andthe rotor resistance is the key factor in obtaining a high-performanceand high-efficiency induction motor drive. The rotor flux is estimatedusing the induction motor rotor-circuit model. Although the estimatedrotor flux is insensitive to the stator-resistance variation, it does de-pend on the rotor resistance. A stable model reference adaptive system(MRAS) rotor-resistance estimator insensitive to stator-resistance vari-ation as well as a load torque estimator have been designed. The use ofcascade sliding mode control structure and continuous adaptive updateof the machine parameters ensures accurate flux estimation and high-performance operation. Simulation results are presented to verify thestability of the induction-motor drive in various operating modes.

Index-Terms: Induction motor, cascade sliding mode controller de-sign, vector control, parameters estimation.

Mohammad S. Sharawi and Malik Al-Qdah

Philadelphia University, Jordan

Abstract

A major bottleneck in today’s computer system performance is thespeed of the main memory bus. A memory bus should be carefullydesigned for good signal integrity (SI) and timing performance. Thispaper presents the design, modelling and simulation of a double data ratesynchronous dynamic RAM (DDR-II SDRAM) memory bus operatingat 400/533Mbps. Three bus topologies are investigated and compared interms of the amount of inter-symbol-interference (ISI) and the eye-width(EW). The topology with on-die-termination (ODT) gave about 95%improvement in ISI reduction, and about 37% and 12% improvementin the eye-width for the worst case write and read operations for the400Mbps data rate, respectively, when compared to the conventionalmother board termination (MBT) scheme.

Abstract

In recent years, multiphase machines are gaining an increasing interestdue to the advantages they possess compared to the conventional threephase machines. One of these advantages is their additional degrees offreedom.In this paper, extensive simulation studies of series connectedmultimachines system supplied by a single inverter are presented. Thissystem consists of a six-phase induction machine and a three-phase in-duction machine. The stators windings of both machines are connectedin series in appropriate manner.The dynamic decoupling of each machinefrom the group is obtained using the indirect vector control algorithm.Mathematical modeling of the multimachine system showed the possi-bility of independent control of each machine in the group. The inde-pendent control is demonstrated by analyzing the characteristics of thetorque and speed of each machine obtained via simulation of multima-chine system under indirect vector control scheme. However, the inde-pendent control scheme is model-based thus very sensitive to changesin certain parameters of the series connected machines. To overcomethis problem, these parameters are estimated on line and used to updatethe control scheme. The simulation results obtained demonstrate theimproved robustness of the multimachines system under the proposedcontrol algorithm.

Supply current and load voltagedistortions suppression using the unifiedpower quality conditioner

Hind Djeghloud, Hocine Benalla andAmar Bentounsi

Electrotechnics Laboratory, Engineer Sciences Faculty, Constantine Universty,

Algeria

Abstract

A straightforward approach to suppress three-phase supply currentand load voltage distortions is presented. This latter uses the unifiedpower quality conditioner (UPQC) topology made up of a hybrid activepower filter (APF) combination based on a series APF, sharing a com-mon DC voltage with a parallel APF, and passive filters. Supply currentdistortion is introduced by connecting a non-linear load, while load volt-age distortion occurs after adding fifth and seventh harmonics to the ACmain voltage. The series APF controller forces load voltage to be sinu-soidal, whereas parallel APF and passive filters counter harmonic con-tents from supply current. A model established under Matlab-Simulinksoftware shows the performance of such approach.

Abstract

The control and monitoring of drinking water is becoming more andmore interesting because of its effects on human life. Many techniqueswere developed in this field in order to ameliorate this process controlattending to rigorous follow-ups of the quality of this vital resource.Several methods were implemented to achieve this goal. In this paper, acomparative study of two techniques resulting from the field of the arti-ficial intelligence namely: RBF Neural Network (RBF-NN) and SupportVector Machine (SVM), is presented. Developed from the statisticallearning theory, these methods display optimal training performancesand generalization in many fields of application, among others the fieldof pattern recognition. Applied as classification tools, these techniquesshould ensure within a multi-sensor monitoring system, a direct andquasi permanent control of water quality. In order to evaluate their per-formances, a simulation using real data, corresponding to the recognitionrate, the training time, and the robustness, is carried out. To validatetheir functionalities, an application is presented.

Abstract

This paper analyzes the problematic of the interferences created bywind farms. Wind turbines may cause interferences to television and mi-crowave signals due to reflections and diffractions of those signals fromboth the tower (stationary) and the blades (non-stationary). The ITURadiocommunication Assembly, on the BT 805, specifies a simplifiedmodel of impairment caused to television reception by a single windturbine considering only free space propagation. This paper shows theextensions to a multiple turbine case, the inclusion of other propaga-tion models (plain earth and ITU-R P.1546) and presents more accuratemodels to obtain the scattering produced by a wind turbine, as well astheir implementation on friendly-use software.

A parallel architectural implementation ofthe fast three step search algorithm forblock motion estimation

Batta Srinivasa Rao and Indrajit Chakrabarti

Indian Institute of Technology Kharagpur, India

Abstract

This paper proposes a parallel architecture for a fast three step search(FTSS) algorithm, which is used in motion estimation. FTSS algorithminvolves reduced number of search points and is thus less computationallyexpensive compared to the standard three step search (TSS) algorithm.Degradation of performance while applying the FTSS algorithm to sev-eral standard images has been shown to be insignificant compared to thestandard TSS algorithm. The proposed architecture uses only three pro-cessing elements accompanied with use of intelligent data arrangementand memory configuration. A technique for reducing external memoryaccesses has also been developed. The proposed architecture for FTSSprovides an efficient solution for applications requiring real-time motionestimations, because it requires smaller area and power than what wouldbe required to implement TSS. The proposed architecture provides thesolution for low bit-rate video applications like video telephony and tele-conferencing.

Abstract

Segmentation is a fundamental stage in image processing since it con-ditions the quality of interpretation. Fusion in remote sensing has onegoal which is to combine different images obtained by different sensors inone image or in different images in order to improve the content and theresolution of these images. In this research, a new fusion method is im-plemented to improve the segmentation process. This method combinesthe results of different image segmentation methods or combines the re-sults of the same image segmentation method. The new fusion methodconsists of a Genetic Algorithm (GA) to combine each two segmentedimages based on the stability factor which is measured by the FunctionalModel (FM). Experiments conducted on SPOT V, and Landsat 7 ETM+images proved that this method can provide better results comparedto the results obtained from using two different segmentation methods.Two methods ate used in these experiments, Self-Organizing Map andHybrid Dynamic Genetic Algorithm cooperation method (SOM-HGA)and the Iterative Self-Organizing Data (ISODATA) method.

Jiang Huai Pan, He Jia-Zhou and Li Yan-Li

Jiangsu Automation Research Institude, China

Abstract

An algorithm is presented to absolutely registration two 3-D sensorsusing targets that are tracked by both sensors. The algorithm estimatesand removes sensor biases and sensor frame orientation errors, For il-lustrative purposes, the algorithm uses the difference in the position ofa target, as reported by the two sensors, to compute a set of bias pa-rameters. These bias parameters are then applied to align both sensor’strack positional data. The registration algorithm is applicable to thosesituations where there are no sensor location errors, the magnitude ofthe bias errors is small, and these errors do not change with time or veryslowly with time.

Abstract

This work investigated the electrical and morphological properties ofNitrogen Doped Silicon (NIDOS) thin films. The resistivity measure-ments showed an increase in the resistivity values with the increase inthe nitrogen tenor for films annealed at temperatures lower or equalsto 1000◦C. However, for an annealing temperature of 1100◦C, resultsshow an improvement of films conductivity with the increase both, theannealing duration and the nitrogen tenor. The X-ray diffraction andthe SEM observations showed that the film crystallinity increases withthe duration annealing, and that the high nitrogen content inhibits thecrystallization phenomena. The crystallization mode of NIDOS films hasbeen determined using the Kolmogorov-Johnson-Mehl-Avrami (KJMA)model and grain size distribution study. Results show that the nucleationin NIDOS films occurs heterogeneously at the interface NIDOS/SiO2.The crystallites reach the film surface in a one-dimensional way dur-ing a short time and continue to grow laterally The improvement ofthe electrical characteristics of NIDOS films are strongly related to itsmorphological evolution of the amorphous to the polycrystalline phase.

Modeling and computing the electricalparameters of a multichip moduleinterconnections

Hassan Belahrach and Mouloud Satar

Ecole Royale de l’Air, Morocco

Abstract

In this paper, the network analog method is developed with a viewto applying it to compute quasi-static electrical parameters (matricesof capacitance [Cij ], inductance [Lij ], conductance [Gij ] and resistance[Rij ]) of multilayer structures in CMOS technology. Finite-differencemethod with variable increments is applied to solve Laplace’s equation.It involves building a network analog having complex or real branches.Hence, if any advantages can be obtained, one may solve a networkproblem using the network analog method instead of the correspond-ing Laplace’s difference equations. Thus, the number of equations, thecomputational time and the memory space will be considerably reduced.Sample results are presented for conductor line sizes and spacing typicalof multilevel VLSI structures.

Optimal algorithm for the numericalinversion laplace transforms methodin a multiconductor transmission line

Said Ghnimi, Adnen Rajhi and Ali Gharsallah

Electronics Laboratory, Science Faculty of Tunis, Tunisia

Abstract

The current paper presents a study on the numerical method of inver-sion of Laplace transforms (NILT) to deal with some of EMC problemsin MW systems under the Matlab environment. The idea consists instudying the two well used algorithms in NILT, one is called quotient-difference algorithm using expansion of the Fourier series and the otheris called ε-algorithm using the expansion of Laguerre function, in orderto reach an optimal algorithm of the NILT method for different mul-ticonductor transmission line (MTL) systems. The simulation resultsshow that the quotient difference algorithm is most efficient than the ε-algorithm in term of rapid convergence to zero with a low relative error;these performances increase significantly the use of Laplace transforminversion by the method of Laguerre in MW circuits.

Majid Mohammadi and Mohammad Eshghi

Shahid Beheshti University, Tehran, Iran

Abstract

Quantum gates which are represented by unitary matrices have po-tentials to implement reversible logic circuits. V and V + gates are twowell known quantum gates which are used to synthesize the reversiblelogic circuits. In this paper we have used behavioral description of thesegates, instead of unitary matrix description of quantum gates, to syn-thesize reversible logic circuits. By this method, V and V + gates areshown in the truth table form. Results show that bigger circuits withmore number of gates can be synthesized using proposed method. Somebenchmarks of reversible logic circuits are also optimized and comparedwith other works.

A new miniaturized fractal bandpassfilter based on dual-mode microstripsquare ring resonator

Jawad Ali

Department of Electrical and Electronic Engineering, University of Technology,

Iraq

Abstract

A novel fractal dual-mode microstrip bandpass filter design has beenintroduced in an attempt to produce filters with highly miniaturizedsize for modern wireless applications. The filter structure has been gen-erated based on the 3rd iteration Minkowski-like pre-fractal geometry,using the conventional dual-mode square ring resonator as the initiator inthe fractal generation process. The space-filling property, self-similarityand the diagonal symmetry of the structures corresponding to the suc-cessive iteration levels of this fractal geometry have found to producereduced size filter structures with accepted performance. The bandpassfilter structure produced by the third iteration of this fractal geometrycan be considered as a novel design with adequate performance. Thisdesign structure possesses a size reduction of about 72% compared withthe conventional dual-mode square ring resonator operating at the samefrequency and using the same substrate material. In addition, the newdesign technique seems reliable, since it provides the filter designers withmore degree of freedom and further size reduction as compared withthose reported in the literatures.

Abstract

In this paper, a new design of spatial filter for uniform linear array ispresented. The array factor is expressed in terms of cosine, sine and lin-ear functions of frequency which serves as an alternative to Chebyshevpolynomials. The simple filter design has good stopband attenuationwith the use of trigonometric functions with less filter complexity. Novelslope equalization technique of the filter design reduces ripples at thetransition edges hence further improves its stopband attenuation. Pro-posed filter replaces Dolph-Chebyshev window in the design of a uniformlinear array beamformer.
