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

REVIEW doi:10.1038/nature10676 Multigate transistors as the future of classical metal–oxide–semiconductor field-effect transistors Isabelle Ferain1‚ Cynthia A. Colinge1 & Jean-Pierre Colinge1 For more than four decades‚ transistors have been shrinking exponentially in size‚ and therefore the number of transistors in a single microelectronic chip has been increasing exponentially. Such an increase in packing density was made possible by continually shrinking the metal–oxide–semiconductor

Chapter 1 The History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers

AUTO MUTE FOR AUDIO DECK (Automatically Mute Your Audio System when you receive a call) Muting car’s audio deck‚ while talking on cell phone is an important yet difficult task. This project is designed to solve the problem. A sensitive IR transmitter and receiver pair is designed and fixed to a cell phone holder. Always the cell phone should be placed in the holder. The transmitter unit continuously transmits IR rays. These IR rays are interrupted by the cell phone. Whenever the cell phone

1. Discuss one of the skin physical properties that assigned to your group. Sweating is one of the categories of the physical properties of skin. To simulate the sweating of the skin properties‚ metals and textiles are the materials to simulate the sweating properties. One of the properties of sweating is evaporation. Evaporation involves a liquid changing to a gas. The liquid particles with high enough energy can escape from the surface of the liquid. These form a vapour above the liquid surface
