A cofferdam is a temporary structure designed to keep water and soil out of the excavation in which a bridge pier or other structure is built.

The method of variation of parameters is the general method which we use to find out a particular solution of a differential equation by replacing the constants in the solution of the homogeneous differential equation by functions and evaluating these functions so that the original DE will be satisfied.

“Caissons” means box. Such box can be prefabricated on shore and then floated to the desired site, and is allowed to seat on prepared base.

In Reaction turbine, Pressure energy is first converted into kinetic energy before supplied to runner. It works on impulse reaction principle.

The principle of under-reamed pile foundations is the anchoring of the superstructure at a depth where the volume changes of soil are negligible.

Seismic waves are the waves which are formed by sudden breaking of rock within the earth. There are two types of waves: Body and Surface waves.

Frequency Modulation is the technique in which the frequency of a carrier signal is varied according to the message signal.

The amplitude of the carrier signal varies in accordance with the instantaneous amplitude of the modulating signal in Amplitude Modulation.

CMOS is a new type of MOSFET logic is made combining both the PMOS and NMOS processes and is called complementary MOS.

Crystal Oscillator is specially designed in a circuit to provide low impedance when it operates in series-resonant mode and high impedance.

There are three operational amplifiers in the circuit of an Instrumentation Amplifier of which two non inverting amplifiers are the inputs.

Well foundation is deep one which generally provided for construction of bridges.World famous “Taj mahal” stands on well foundation.

The entropy of a substance is a real quantity, just like pressure, volume and temperature. Its unit is joule/Kelvin (J/K).

A draft tube is a pipe of gradually increasing diameter which connects the exit of runner of a turbine to the tail race.

A crystal is a solid whose constituent atoms, ions or molecules are closely packed in a regular fashion with repeating pattern in three dimensions.

In Tidal Power plants, tidal energy gets generated. It is renewable source of hydro energy which is available due to rise and fall of tides.

Unsupervised learning is the process of training a machine with data that hasn’t been classed or labeled.

supervised learning involves the presence of a supervisor who also serves as an instructor.

It all comes down to taking the appropriate actions to maximize your return in every given situation.

Nanotechnology is dealing with the characterization, design, production and various applications of nanostructures and nanosystems.

The abbreviation for Java Database Connectivity (JDBC) is Java Database Connectivity.

macroeconomic theories include theories of economic growth and development, national income, money, international trade, employment, and general price levels.

Scope of business economics is the application of economic theory and methodology to business.

Diseconomics of scale occurs when the long-term average cost of an organization increases. It can occur when the tissue becomes excessively large.

Nanotechnology have considered as the solution to our smallest to biggest problems. Applications of Nanotechnology are countless.

David Ricardo, an English classical economist, first developed a Ricardian theory of rent in 1817 to explain the origin and nature of economic rent.

Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.

e-Rupi is designed as a digital payment system which enables users to access the service with the help of SMS or QR bar.

free energy refers to the amount of internal energy in a thermodynamic system that is available to do work. There are different forms of thermodynamic free energy

Petroleum Refining is defined as the industrial process of production of useful petroleum products from crude oil. The crude oil in its raw form is a dark and sticky liquid which is not useful. To get the usable products from the crude oil, it needs to be refined.
