Abstract—
Low-voltage operation for memories is attractive because of lower leakage power and active energy, but the challenges of SRAM design tend to increase at lower voltage. This paper explores the limits of low-voltage operation for traditional six–transistor (6 T) SRAM and proposes an alternative bitcell that functions to much lower voltages. Measurements confirm that a 256-kb 65-nm SRAM test chi ....etc

An improvised MOS transistor model suitable for
Geometric Program based analog circuit sizing in
sub-micron technology

A special monomial form of the device model is required by the Geometric program. This article describes the work done in identifying the sources of inaccuracy in this basic model. The strict monomial form has been relaxed. the sizing problem is solved as a series of geometric programs instead of solving it considering as single entity. a folded-cascode op-amp sizing example is used to describe the efficiency of t ....etc

ABSTRACT
Good people all, of every sort, give ear unto my song , this was the cry
made by thousands of operator running to and fro to detect, analyze and report the fault to their
senior officials and wait for their instructions to be followed. Finally someone heard their cry and a
master system was born. The energy is generated, transmitted, distributed and finally utilized. At
every stage certain supervision, control and protection is neces sary. This paper deals with basic
SCADA system, its components, basic block ....etc

an electrical sub-station

abstraction

This is the basic discipline in the field of electrical power transmission

. An electrical sub-station chiefly deals with the distribution of power to the user end from the generator side. So it becomes essential to have proper protection schemes for it

. So it is necessary for every electrical engineer to know the dynamics of the functioning of it.

Introduction


The present day electrical power system is a.c. i.e. electric power is generated, transmitted and distributed in the form of Alternating current. The electric power is produce at the power station, which are located at favorable places, generally quite away from the consumers. It is delivered to the consumer through a large network of transmission and distribution. At many place in the line of power system, it may be desirable and necessary to change some characteristic ( e.g. Voltage, ac ....etc

FIBRE-REINFORCED FLY ASH SUB-BASES IN RURAL ROADS

SUB-BASE COURSES AND THEIR EVALUATION

SUB-BASE IS MADE OF BROKEN STONES,BOUND OR UNBOUND AGGREGATE

SUB-BASE COURSE PRIMARILY HAS THE SIMILAR FUNCTION AS OF THE BASE COURSE AND PROVIDED WITH INFERIOR MATERIALS THAN OF BASE COURSE

THE FUNDAMENTAL PURPOSE OF SUB “BASE IS TO PROVIDE A STRESS TRANSMITTING MEDIUM TO SPREAD THE SURFACE WHEEL LOADS IN SUCH A MANNER TO PREVENT SHEAR AND CONSOLIDATION DEFORMATIONS

FILL ALGORITHMS

Given the edges defining a polygon, and a color for the polygon, we need to fill all the pixels inside the polygon.
Three different algorithms:
1. Scan-line fill
2. Boundary fill
3. Flood fill
Boundary Fill
Suppose that the edges of the polygon has already been colored.
Suppose that the interior of the polygon is to be colored a different color from the edge.
Suppo ....etc
