HOVERCRAFT
1. INRODUCTION
Vehicles designed to travel close to but above ground or water. These vehicles are supported in various ways. Some of them have a specially designed wing that will lift them just off the surface over which they travel when they have reached a sufficient horizontal speed (the ground effect). Hovercrafts are usually supported by fans that force air down under the vehicle to create lift, Air propellers, water propellers, or water jets usually provide forward propulsion. Air-cushion vehicles can att ....etc

1.INTRODUCTION
1.1 GREEN ENGINEERING:
Green Engineering is the design, commercialization and use of processes and products that are feasible and economical while:
  Reducing the generation of pollution at the source.

  Minimizing the risk to human health and the environment.
 Green engineering embraces the concept that decisions to protect human health and the environment can have the greatest impact and cost effectiveness when applied early to the design and development phase of a process o ....etc

ABSTRACT
In the future, the current method of magnetically storing data may reach its limit of maximum achievable density. Hence we need a data storage technology which has high storage capacity and is small in size. The solution is Thermomechanical data storage. Thermomechanical Data Storage is a data storage scheme in which nanometer sized pits on a plastic disc represent digital data. This data storage concept combines ultrahigh density, terabit capacity, small form factor and high data rates. By using this concept, we w ....etc

Abstract
The paper deals with the use of wavelet transform for signal and image de-noising
employing a selected method of thresholding of appropriate decomposition coef-
¯cients. The proposed technique is based upon the analysis of wavelet transform
and it includes description of global modi¯cation of its values. The whole method
is veri¯ed for simulated signals and applied to processing of biomedical signals
representing EEG signals and MR images corrupted by additional random noise.
1 Introduction
The wavelet transfo ....etc

Abstract
Molecular electronics (sometimes called moletronics) is an interdisciplinary theme that spans physics, chemistry, and materials science. The unifying feature of this area is the use of molecular building blocks for the fabrication of electronic components, both passive (e.g. resistive wires) and active (e.g. transistors). The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by molecular-level co ....etc

ABSTRACT
Mathematical transformations are applied to signals to obtain further information from the signal that is not readily available in the raw signal. By applying the various transformations available today, the frequency information in these signals is obtained. There are many transforms that are used quite often by engineers and mathematicianâ„¢s. Hilbert transforms, short-time Fourier transforms, Radon transform, and the Wavelet transform constitute only a small portion of a huge list of transf ....etc

1 .INTRODUCTION

In the 21st century, the nanometer will very likely play a role similar to the one played by the micrometer in the 20th century The nanometer scale will presumably pervade the field of data storage. In magnetic storage today, there is no clear-cut way to achieve the nanometer scale in all three dimensions. The basis for storage in the 21st century might still be magnetism. Within a few years, however, magnetic storage technology will arrive at a stage of its exciting and successful evolution at which fund ....etc

Mesotechnology describes a budding research field which could replace nanotechnology in the future as the primary means to control matter at length scales ranging from a cluster of atoms to microscopic elements. The prefix meso- comes from the Greek word mesos, meaning middle, hence the technology spans a range of length scales as opposed to nanotechnology which is concerned only with the smallest atomic scales.
