Environmental noise is a growing priority. Concerns about avi at ion noise have essentially halted airport expansion in large metropolitan areas, which has increased congestion, reduced safety margins, and impacted economic development. Community response to highway traffic noise is beginning to cre at e the same conflict between economic development, safety, and environmental concerns for ground transport at ion systems. Environmental noise is a complex systems problem with significant sociological, physiological, or policy elements as well as ....etc

Abstract
The proper design and simulation of modern electronic microsystems oriented towards environment monitoring requires accurate models of various ambient sensors. In particular, this paper presents a comprehensive model of an ion sensitive field effect transistor (ISFET). The model can be employed straightforwardly for simulations at device, circuit or system level. First, the model was validated with electrical measurements a ....etc

Pile driving at large construction sites produces formidable noise. Marine pile driving similarly can produce high sound pressures underwater”but these can be lethal to fish and can harass marine mammals, including those protected by federal law. This problem has contributed to costly construction delays on major bridge projects. To protect marine life, engineers have designed air bubble curtains to reduce underwater sounds. Air provides an effective barrier to sound propagating through water, because of the difference in density betwee ....etc

STEGANOGRAPHY

Steganography is essentially a security measure for passing concealed messages, so as the message will not be detected. The goal of steganography is to hide the fact that the message exists. Steganography, which comes from the Greek language, meaning covered or secret writing, is the art of hiding information such as a message within images, audio, text and video. Steganography encompasses methods of transmitting secret messages through innocuous cover carriers in such a manner that the very existence of the hi ....etc

With future threats emerging and the overall needs of the military changing, the armor mechanics community is always exploiting new materials and technologies to stay at the forefront of defense capabilities. Along these lines, this presentation will cover some of the research conducted at the Army Research Laboratory (ARL) and will be given in two parts. The first part will cover recent work completed on the ballistic testing of two silicon carbides with varying porosity distributions. The second part will go over a brief introduction of the w ....etc

Abstract
CRYPTOGRAPHY:
Cryptography is an algorithmic process of converting a plain text message to a cipher text message based on an algorithm that both the sender and receiver know, so that the cipher text message can be returned to its original, plain text form. In its cipher form, a message cannot be read by anyone other than the intended receiver. The act of converting a plain text message to its cipher text is called enciphering. Reversing that act is deciphering. Enciphering and ....etc

LANDSCAPING FOR ENVIRONMENTAL PURPOSES


INTRODUCTION
Energy saving is possible with landscaping.

Although it is not possible to control temperature ,wind and other natural elements certain landscape particles can help modify the climate in and around the home.

By placing trees,shrubs,vines and landscape structures properly home owner reduce the energy required to keep homes comfortable during winter and summer.Along with the reduction of energy bills,a well planned landscape adds beauty,interest and in ....etc

Special Purposes Concretes
Introduction
The properties of concrete depend on the quantities and qualities of its components. Because cement is the most active component of concrete and usually has the greatest unit cost, its selection and proper use are important in obtaining most economically the balance of properties desired for any particular concrete mixture.
History of the origin of cement
It is uncertain where it was first discovered t ....etc
