to: Prof. Karthikeyan A. Faculty‚ Electronics Engineering VIT University. As an assignment for IInd semester for the session 2010-11. Problem Statement: To design and implement a Water Level Indicator‚ using Electronic devices like LEDs‚ ICs‚ Transistors‚ etc. The reason behind taking this problem into consideration was there occurs a huge wastage of water due to overflow in overhead tanks. Approach to Problem Solution: Our main requirements for the indicator are as follows:

communication theories. Among of these theories‚ interpersonal communication (IC) and organizational communication (OC) are the most commonly-used theories applied in business to help us resolve problems. IC‚ as a kind of device that organizers usually use to communicate with their employees‚ more emphasizes individuals interacting face-to-face than OC. It can help us understand how and why people think and behave. However‚ IC is hardly defined in its own area of study‚ yet often occurs within other

(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 and present day computers are also categorized

at fulfilling such small goals‚ using the 3-terminal voltage regulator LM317. The circuit consists of an IC LM317 and a set of resistors and capacitors‚ in addition to the transformer and the rectifying element. The AC voltage‚ from the mains supply is initially stepped down to the desired voltage‚ which is then rectified to be applied to the input terminal of the voltage regulator IC. As mentioned earlier the voltage regulator then takes care of supplying a constant voltage at the output terminal

At the beginning‚ the Electronic Testing Operations (ETO) measured two components of cost: direct labor and burden‚ but the burden is grouped into a single cost pool that includes all costs and divided by direct labor dollars to obtain the burden rate. (Q2) ETO’s manager picked up 5 components to evaluate the impact of different accounting system. The reported costs from existing system can be computed as follows‚ given the burden rate 145%: Product Direct Labor Burden Total Costs ICA 917 1
