CHAPTER I THE PROBLEM AND ITS SETTING INTRODUCTION The area of wireless power transmission is very interesting. The technology is in its infancy but the overall benefits from its maturation could be significant to society as a whole. World population is expected to continue to grow exponentially. Five sixths of the world’s population lives in developing nations. Most developing nations such as China‚ India‚ and Pakistan are rapidly improving their standard of living. All of these trends point

Mitigation of Disturbances by Shunt Active Power Filter Using Wavelet Transforms Abstract— The effect of Power Quality (PQ) Disturbances on power utilities are increasing day by day with wide spread use of non – linear loads. “Harmonics is one such disturbance which will cause the power system”. These disturbances are detected and compensated in a better means by using Active Power Filters (APF). The identification and reference current generation is carried out by using Wavelet Transform (WT) Theory

CHAPTER 1 1.0 INTRODUCTION Students’ Industrial Work Experience Scheme (SIWES) is a skill development program designed to prepare students of Universities‚ Polytechnics/monotechnics and colleges of education for transition from the college environment to work (Akerejola 2008). Oyedele (1990) state that work experience is an educational program in which students participate in work activities while attending school. 1.1 brief histories of SIWES The Students’ Industrial Work Experience Scheme (SIWES)
