Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cag ....etc

Procedure:-
1. Read the input sequence, x and plot
2. Read the impulse response of the system, h and plot
3. Convolve the two results and plot them
Description:-
Linear Convolution involves the following operations.
1. Folding
2. Multiplication
3. Addition
4. Shifting
These operations can be represented by a Mathematical Expression as follows:
y =  xh

x= Input signal Samples
h= Impulse response co-efficient.
y= Convolution output.
n = No. of Input sample ....etc

INTRODUCTION
DEFINE :- A pair of linear equations in two variables is said to form a system of simultaneous linear equations
The general form of pair of linear equations in two variables x and y is :-
a1x + b1y + c1 = 0
a2x + b2y + c2 = 0
METHODS
The Algebraic Methods of solving simultaneous pair Linear Equations in Two Variables are :-
1) METHOD OF ELIMINATION BY SUBSTITUTION
2) METHOD OF ELIMINATION BY EQUATING THE COEFFICIENTS
3) METHOD OF CROSS-MULTIPLICATION

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

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
