Effects of Linear Induction Motor Parameters in Its Optimum Design Based on Finite Element Method

Mehrdad JafarBoland; AbdolAmir Nekoubin

Volume 3, Issue 1 , January 2009, Pages 1-10

https://doi.org/10.1234/mjee.v3i1.183

Abstract
  Effective parameters in performance of linear induction motors such asair gap, number of poles and the thickness of secondary must be selected and optimized to increase power coefficients and motor performance significantly. In this paper a double sided linear induction motor in different conditions ...  Read More

Optimum Distribution Generator Placement in Power Distribution System Using Ant Colony Algorithm

Ghazanfar Shahgholiyan; MohamadAmin Heidari; Mehdi Mahdavi

Volume 3, Issue 1 , January 2009, Pages 11-18

https://doi.org/10.1234/mjee.v3i1.184

Abstract
  The recent development in renewable energy systems and the high demand for having clean and low cost energy sources encourage people to use distributed generator (DG) systems. Proper addition and placement of DG units can increase reliability and reduce the loss and production cost. In this paper using ...  Read More

Bit Rate Reduction of FS-1015 Speech Coder Using Fuzzy ARTMAP and KSOFM Neural Networks

Mansour Sheikhan; Davood Gharavian; Ali Eslamzadeh

Volume 3, Issue 1 , January 2009, Pages 19-26

https://doi.org/10.1234/mjee.v3i1.153

Abstract
  The speech spectrum is very sensitive to linear predictive coding (LPC) parameters, so small quantization errors may cause unstable synthesis filter. Line spectral pairs (LSPs) are more efficient representations than LPC parameters. On the other hand, artificial neural networks (ANNs) have been used ...  Read More

Temperature Effect Investigation of 45nm Silicon-on-Diamond MOSFET Transistors

Arash Daghighi; Azar Farajzadeh

Volume 3, Issue 1 , January 2009, Pages 27-32

https://doi.org/10.1234/mjee.v3i1.141

Abstract
  The self-heating effects (SHE) in 45nm Silicon-on-Insulator (SOI) and Silicon-on-Diamond (SOD) structures were investigated. As a result of high thermal conductivity of diamond, SHE is much less pronounced in SOD structures. This makes SOD transistors suitable for high power applications were large power ...  Read More

https://doi.org/10.1234/mjee.v3i1.185

Abstract
  The expansion of Internet, increases the number of users and applications. Having higher speed and better quality are the main chalanges of computer network development. Using MPLS and proper traffic design, it is possible to improve the quality of service and reduce the possibility of congestion. It ...  Read More

Optimal Choice and Allocation of FACTS Devices to Decrease Power Network Loss's Using Genetic Algorithms

Saeed Abazari; Ghazanfar Shahgholian; Omid Ghanaati

Volume 3, Issue 1 , January 2009, Pages 45-52

https://doi.org/10.1234/mjee.v3i1.186

Abstract
  With increase energy consumption in the world, power network development is necessary but creating a new transmission line is very costly. Therefore increasing line transmission capability is economic. We propose a method to FACTS device to the power network, in this paper and resulted in introducing ...  Read More

A Method for Reducing Memory Effect in RF Amplifier with FIR Filter

MohammadReza Soltani; Rasoul Amirfattahi; MohammadReza Zadhosh

Volume 3, Issue 1 , January 2009, Pages 53-60

https://doi.org/10.1234/mjee.v3i1.187

Abstract
  In this paper we study various techniques of power RF amplifier linearization and analyze the most effective circuits of predistortion digital circuits. We propose a method for adapting this circuit and compare the advantages and disadvantages of this circuit with conventional predistortion circuit. ...  Read More

Automatic Segmentation of Heart Sounds (S1 & S2) Using Wavelet

MohammadAli Saghafi; Rasoul Amirfattahi; Mojtaba Mansouri; Mohsen Kazemi

Volume 3, Issue 1 , January 2009, Pages 61-68

https://doi.org/10.1234/mjee.v3i1.188

Abstract
  In this paper a new method approach is proposed for automatic segmentation of heart sounds (S1, S2) based on wavelet transform. Unlike many other approaches, this method does not use ECG as reference for detection. The applied criterion for segmentation is based on a very important physiologic attribute ...  Read More
