"Were we to seize and eliminate from our industrial world the results of Mr. Tesla ’s work‚ the wheels of industry would cease to turn‚ our electric cars and trains would stop‚ our towns would be dark‚ our mills would be dead and idle. Yes‚ so far reaching is his work that it has become the warp and woof of industry... His name marks an epoch in the advance of electrical science. From that work has sprung a revolution..." -B.A. Behrend If you were to go to an encyclopedia and tried to find

A Power Line Communication Explained (1984) Challenges and Technologies Abstract This paper reviews the sources of attenuation‚ noise and distortion encountered when communicating over AC power wiring. Various technologies which have been used to address these challenges‚ such as spread spectrum and digital signal processing‚ are then examined in light of the known channel conditions. Introduction While the idea of sending communication signals on the same pair of wires as are used for

Electronic WorkBench tutorial Introduction Electronic WorkBench (EWB) is a simulation package for electronic circuits. It allows you to design and analyze circuits without using breadboards‚ real components or actual instruments. EWB’s click-anddrag operations make editing a circuit fast and easy. You can change parameters and circuit components on the fly‚ which make "what-if" analysis straight foreward. This tutorial is intended as a quick introduction to EWB’s basic features. It first

Table of Contents INTRODUCTION 3 MATLAB SIMULATION 4 DISCUSSION 8 REFERENCE 10 INTRODUCTION Synchronous generators or alternators are synchronous machines used to convert mechanical power to ac electric power. Nowadays‚ an isolated synchronous generator supplying its own load independently of other generators is very rare. Such a situation is found in only a few out-of-the-way applications such as emergency generators. For all usual generator applications‚ there is more than one generator

Innovation vs Entrepreneurship Navin Kumar Prasannam – 24C “Necessity is the mother of invention” is an English proverb meaning that difficulty or need for ease bolsters inventions aimed at killing those difficulties. This is where an innovator steps in and ensures‚ with all his creativity‚ that there is a product designed to satisfy the necessity. But who ensures the success of the product in terms of its utilization or market share‚ when compared to its rivals? According to the Oxford Dictionary
