Generator reactances are used for two distinctly different purposes. One use is to calculate the flow of symmetrical short circuit current in coordination studies. A second use for generator reactances are in specifications that limit the sub-transient reactance to 12% or less in order to limit the voltage distortion induced by non-linear loads. For either short circuit or harmonic distortion analyses‚ the stated reactances will need to be converted to a common base to make valid comparisons. Typically

generation computer. Second generation (1959-1965) computer consisted of transistors i.e. vacuum tubes were replaced by transistors. Thus the size of the computer got reduced considerably. Third generation (1966-1973) computer consisted of integrated circuits (IC) i.e. many transistors in single silicon chip. A single IC has many transistors‚ registers and capacitors built on a single thin slice of silicon. With the invention of microprocessor (1971)‚ fourth generation of computer evolution started

These include the desktop that is in many homes to the cell phones in your pocket. Even things like your car‚ dishwasher‚ dvd player‚ and even TVs include some form of computers. All this would not be possible without the invention of the integrated circuit or IC. This led to the creation of the Microprocessor or CPU (central processing unit) which acts as the brain of the computer. To better help illustrate the function and need for a CPU you must go back to the first all electric computers. Now computers

Change Plan: Circuit City Kara Burke Keller Graduate School of Management One major change that took place in the Circuit City organization was its bankruptcy and liquidation of its assets. I was unable to find any communications that occurred within the organization‚ much less externally to stakeholders. What I was able to find were many news communication pieces from third parties. The communications highlighted all the stages of this change‚ from the announcement of bankruptcy filing to

Q-Meter The Q meter is an instrument used to measure electrical properties of coils and capacitors. Mostly used in testing the radio frequency circuits. A Q-meter basically measures the Q (Quality Factor) of the circuit. It is also used to test the inductors‚ capacitors for their high frequency inductance‚ Q ‚ capacitance as well as ∑‚ tg δ value.

State Machine (FSM) is a kind of digital circuit‚ (and‚ possibly‚ other types of machines‚ including virtual ones) that is used to process information in steps (states). At every state a different part of the information can be processed. This has many advantages in terms of reduced hardware requirements over combinational logic networks (CLNs). It is a mathematical model of computation used to design both computer programs and sequential logic circuits. It is conceived as an abstract machine that
