Two aspects of attacks on steganography are detection and destruction of embedded message. Any object can be manipulated with the intent of destroying some hidden information whether an embedded message exist or not. .

Attacking steganographic algorithm is very similar to attacking cryptographic algorithms and similar techniques apply. If the original unmodified file used as a cover by the stegosystem is available to an attacker or investigator all he has to do is a bit-by-bit comparison with the suspect version in order to establish steganogr ....etc

An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine the expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine. The force is applied typically to pistons, turbine blades, rotor or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechani ....etc

A stroboscope also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. It consists of either a rotating disk with slots or holes or a lamp such as a flashtube which produces brief repetitive flashes of light. Usually the rate of the stroboscope is adjustable to different frequencies. When a rotating or vibrating object is observed with the stroboscope at its vibration frequency (or a submultiple of it), it appears stationary. Thus stroboscopes are also used to measure frequency.Th ....etc

Abstract
Organic electronics, (plastic electronics or polymer electronics), deals with conductive polymers, plastics, or small molecules. It is called 'organic' electronics because the polymers and small molecules are carbon-based, like the molecules of living things. This is as opposed to traditional electronics (or metal electronics) which relies on inorganic conductors such as copper or silicon. Polymer electronics are laminar electronics

Techniques for Rehabilitation & Repair Of Structures

Introduction

The success of repair activity depends on the identification of the root cause of the deterioration of the concrete structures. If this cause is properly identified, satisfactory repairs can be done for the improvement of strength and durability, thus extending the life of the structure, is not difficult to achieve. General procedure in the repair of distressed concrete structure:

Support the structural members properly as required.
Remove all cracked, spalled and l ....etc

REPAIRS, REHABILITATION AND RETRO-FITTING
Significance of Ferrocement repairs
After, we in India, started manufacture of concrete in years 1930 s, the negative aspect of concrete started showing after sometime as below:-
- Deterioration due to poor workmanship, particularly high water content and corrosion of reinforcement and R.C.C. Technology being new.
- Leakages in concrete due to rain water as well as in water retaining structures
This menace become conspicuous after construction works which became old about 20 to 30 years. We star ....etc
