Today, the situation on low-voltage AC systems has become a serious concern.The quality of electrical power in commercial and industrial installations is undeniably decreasing. In addition to external disturbances, such as outages, sags and spikes due to switching and atmospheric phenomena, there are inherent, internal causes specific to each site and resulting from the combined use of linear and non-linear loads.Untimely tripping of protection devices, harmonic overloads, high levels of voltage and current distortion, temperature rise in condu ....etc

Test case Reduction-An Experimental Analysis through Coverage Techniques



. INTRODUCTION
Testing plays an important role in all the phase of Software Development Life Cycle (SDLC).Testing software with all possible values provides more confidence about the quality and reliability of the software. In this technique, Test manager executes the programs with all infinite combinations of values for program variables .Generally the domain of a program is infinite and cannot be us ....etc

ADAPTIVE TECHNIQUES BASED HIGH IMPULSIVE NOISE DETECTION AND REDUCTION OF A DIGITAL IMAGE
ABSTRACT
As reducing impulse noise in a digital image is a very active research area in image processing, this paper proposes a novel algorithm for digital image impulsive noise detection and reduction based on adaptive nonlinear techniques which seems to be a boom in digital image restoration process. The main objective of this algorithm is to consider a particular digital image as input and make the preprocessing to remove the impulsive ....etc

Iam a final year b.tech student of EEE branch. I hav just started with my project work(Harmonic Reduction in Three phase Parallely Connected Inverter).Iam facing problem in triggering the thyristors using MATLAB,Simulink software as i do not know anything about the MATLAB software. Can anyone please guide me in solving this problem and give information regarding my project? The methods which i want to use to reduce harmonics are:
1.filters
2.transformer connections
3.Pulse Width Modulation(PWM)
4.Third Harmonic Injection Pulse Width Modulat ....etc
