Engineering

The Conventional Energy Sources are helpful in producing electrical power generation from Hydro, Thermal, Nuclear and Diesel power stations.

An annuity is a sequence of equal payment or a sequence of regular payment at regular intervals or in other words.

We can lent or borrow money from one entity to another. The price to be paid for the use of a certain amount of money for a certain period of time is known as interest.

The 8255 microprocessor is also known as Programmable Peripheral Interface. It has 24 I/O pins. The three 8 bit ports are PA, PB, PC.

An interrupt is a condition that arises during the working of a microprocessor. The interrupts of 8086 initiate interrupt service through ISR

The DC Motor is an electrical machine which converts mechanical energy into electrical energy. It works on the principle of induced emf.

The DC Motor is an electrical machine which can be classified as Separately excited DC Motor, Permanent Magnet and Self excited DC Motor.

The precision rectifier has the capability of rectifying voltages which are of smaller magnitude than the forward voltage drop.

The circuit which produces the samples of the input voltage and holds those values for a definite amount of time is sample and hold circuit.

The losses in optical fiber are Absorption loss, scattering loss, dispersion loss, radiation loss and coupling loss.

Taylor series method to solve the first order ordinary differential equation- The general first order differential equation

We can lend or borrow money from one entity to another. The price to be paid for the use of a certain amount of money for a certain period of time is known as interest.

Sequencing: Processing n-jobs through 2 machines Consider n jobs (say 1,2, …n) to be processed on two machines A and B, in the order AB.

We denote the product of the positive integers from 1 to n by n! and we read it as “factorial

When we apply any of the following operation on a matrix, then it is called an elementary transformation.

The determinant of a matrix is a number that associated with the square matrix. This number may be positive, negative or zero.

An equated monthly instalment(EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month.

The population is the collection or group of observations under study in a survey sampling.The total number of observations in a population is known as population size and it is denoted by N.

Successive differentiation is the process in which we can differentiate the function successively multiple times and the derivative we find is called the successive derivative.

compound interest is calculated on interest as well as on principal. Therefore, compound interest is sometimes described as ‘interest on interest’.

Linear programming problems having two variables can be easily solved by a graphical method which provides a pictorial representation of the solution and we get insights into the basic concept used in solve LPP.

Probability theory: In many real life situations when we are unable to forecast the future with complete certainty. That is, in many decisions, we face the uncertainty. This leads to the study and use of the probability theory.

Integration is the reverse process of differentiation. It is also called anti-differentiation.

Sequencing problems deals with the selection of an optimum order for the number of jobs to be performed with a finite number of facilities.

A distribution is said to be a binomial distribution if the following conditions are met. 1. Each trial has a binary outcome (One of the two outcomes is labeled a ‘success’)

A Servo motor is similar to an induction motor having two primary windings placed 90 degrees apart in magnetic position.

The IMPATT diode (Impact ionization Avalanche Transit-Time) is one which is used in high frequency applications and is a high power diode.

Wien bridge oscillator is an audio frequency sine wave oscillator of high stability and simplicity with no phase shift in feedback network.

The Feedback amplifiers increase the signal strength by providing feedback back to the system at the input end.

The Nyquist criteria is a semi graphical method that determines stability of CL system investigating the properties of the frequency plot.
