High-Speed VLSI Arithmetic Units: Adders and Multipliers


Introduction

Digital computer arithmetic is an aspect of logic design with the objective of developing
appropriate algorithms in order to achieve an efficient utilization of the available hardware .
Given that the hardware can only perform a relatively simple and primitive set of Boolean
operations, arithmetic operations are based on a hierarchy of operations that are built upon the
simple ones. Since ultimately, speed, power and chip area ar ....etc

Underfrequency Protective Relay

The underfrequency relay (fig. 4-16) is a solidstate device that functions to protect the load in the event generator frequency decreases below preset limits. It actuates when the frequency decreases to 55 hertz for 60-hertz operation and 46 hertz for 50-hertz operation. Upon actuation, contacts within the relay close to signal the annunicator and open to de-energize the generator breaker (contactor), resulting in a display of the fault condition and removal of the load from the generator.

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

GPUs - Graphics Processing Units



Introduction

Before we dive into the architectural details of some example GPUs, we'll have a look at some basic concepts
of graphics processing and 3D graphics, which will make it easier for us to understand the functionality of
GPUs

What is a GPU?

A GPU (Graphics Processing Unit) is essentially a dedicated hardware device that is responsible for translating
data into a 2D image formed by pixels. In this paper, we will focus on the 3D graphics, since that ....etc

Growth pattern of Small Scale Units
of Women Entrepreneurs:
A Study of Ernakulam District - Kerala
Mol P. Koshy*
Mary Joseph T.
Women entrepreneurship in Kerala, though lagging behind
many other states in India, has taken an upward swing lately.
Growth of small scale industrial units by women entrepreneurs
reflects their grit and tenacity in staying in the market. This
paper analyses the growth patterns of the SSI units of women
entrepreneurs in Kerala, Ernakulam district, which is the most
industrialized district in the State, was ....etc

effect of avenue tree on temperature under canopy and outside

A well-known effect of urbanisation is the warming of the local climate relative to surrounding rural areas, creating a
phenomenon known as the urban heat island (UHI). UHI intensity varies across a city and over time, but temperature
differences may reach 9 C in the UK. Factors that contribute to a UHI include the thermal properties, height and
spacing of buildings, the production of waste heat, air pollution, and differences in land cover and albedo. The UHI
effect is important ....etc
