This project is aimed at analyzing the available methods for solving a system of linear equations of the form n x n. Using a couple of iterative and/or direct methods, implement a program for these methods that could be run on a parallel
processor. At the end, a graph can be plotted with time taken for execution of a method considered V/s number of processors used (2, 4, 8, 32). For example following questions need to be addressed “
1. For a method considered, evaluate that as the number of processors is increased does the time taken ne ....etc

Power Factor Correction of Linear and Non-linear Loads Employing a Single Phase Active Power Filter Based on a Full-Bridge Current Source Inverter Controlled Through the Sensor of the AC Mains Current
Abstract:
In the last years the number of non-linear loads has been increasing rapidly. This non-linear load had drawn a current form the AC Mains with harmonic components, leading to low power factor, low efficiency, interference by the EMI, among others. A classic solution is the use of passive filters, which ....etc

Electro-dynamic Suspension (EDS), Urban MagLev, Linear Synchronous Motor (LSM), Permanent
Magnet (PM), Pulse Width Modulation (PWM)
Abstract
A new concept in Urban Maglev transportation design is in the testing phase. The vehicle uses
permanent magnets (PM) for both the electro-dynamic suspension (EDS) and linear synchronous
motor (LSM) propulsion. Because of the 3D coupled non-linear velocity-dependent magnetic
levitation, the LSM must provide stabilizing forces to the vehicle. To do this, Vector Control is used

Robust RBFN Control for Linear InductionMotor Drive Using FPGA
An FPGA based radial basis function network(RBFN) is presented here which is used to control the mover position of a Linear induction motor(LIM). First, an indirect field-oriented mechanism is tried for the purpose of speed control of a LIM. Then a sliding-mode control is designed in which a a conservative constant lumps up the uncertainities. As the lumped uncertainity cannot be determined in the practical situations, the RBFN control is used for the purpose of approxim ....etc

ADAPTIVE AND NON-LINEAR EXCITATION CONTROL OF SYNCHRONOUS GENERATOR‟S STABILITY THROUGH NEURAL NETWORK

ABSTRACT
Adaptive and non linear Excitation control of synchronous generator‟s stability through Neural Network Control equipment of synchronous generators such as automatic voltage regulators, speed governors and power system stabilizers have been developed to maintain stability and to improve damping of the power systems. When an operating condition changes greatly, however, such controllers may become less effective b ....etc
