MICROPROCESSOR BASED IMPEDANCE RELAY



INTRODUCTION

In some applications it is necessary that the relay protecting a part of the power system operate for faults within a certain distance of the location on any one of the lines. The protecting scheme accordingly uses distance relays and is divided into three zones. The zones are classified based on the impedance seen by the relay and the relays are hence called impedance relays.

A high frequency electrical current of small voltage and amperage (physiologically safe) passes
between two electrodes situated on the surface of the throat at the level of the thyroid cartilage. The basic
configuration of the device is depicted in Fig.1. The electrodes are made of copper, silver or gold. They
have the form of rings or rectangles covering an area ranging from 3 cm
2
to 9 cm
2
. A third electrode is
often used as a reference for impedance measurements. It may be designed as a separate electrode or as a
ring electrode en ....etc

A Java Framework for Experimentation with Steganography


Definitions

Steganography

1 the art of concealing the existence of information within seemingly innocuous carriers
2 an encrypted message may draw suspicion while a hidden message will not

The Big Idea

1 An image contains more information than can be perceived.
2 Replace the imperceptible bits of a cover image with the bits of a secret message .

INTROUCTION

To begin with, the word tomography can be explained with reference to 'tomo' and 'graphy'; 'tomo' originates from the Greek word 'tomos' which means section or slice, and 'graphy' refers to representation. Hence tomography refers to any method which involves reconstruction of the internal structural information within an object mathematically from a series of projections. The projection here is the visual information probed using an emanation which are physical processes involved. These include physical processes such as radiation, ....etc
