In the world of crafts Air cushion vehicles (ACV) are fast catching up. Air cushion vehicle is a craft that travels on a layer of compressed air just above any kind of surface- land, water, ice etc. Their main area of applications are in military vehicles, helicopters and where transportation using wheeled or tracked vehicles are impossible. Air cushion vehicle (ACV) is a craft that travels on a layer of compressed air just above any kind of surface - land, water, ice, sand, mud etc. The compressed air serves as an invisible cushion that elimin ....etc

INTRODUCTION

The growth of science and technology at an unprecedented pace in the past century was facilitated by the surplus fuel reserves that sustained the developmental requirements in a post industrial revolution era. The oil shock of 1973 brought into existence a sudden setback to this economic growth rate in industrialised nations. The vulnerability of the present developments to be negated by a fuel crisis has shifted the focus of research from better designs during the pa ....etc

Submarine:
Submarines are vehicles designed to operate principally at a considerable depth of water.
Most applications to date are warfare activities. Submarines have also some civil applications like oceanographic researches, pipe laying & servicing well heads at sea bed.
1. Hull:
1.1. Introduction
The aim of this design study is to produce a shape with the following features:
1. Minimum resistance within all other design constraints, thus increasing cruising range, top speed and reducing fuel consumpt ....etc

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

SECURE INTERNET VERIFICATION BASED ON IMAGE PROCESSING SEGMENTATION


ABSTRACT:

From security point of view, fingerprints and biological data in
general constitute sensitive information that has to be protected.
Towards this direction, the method discussed in this paper isolates a
very small fraction of the userâ„¢s biological data, and only this
fraction is stored for future reference. This can also improve the
overall efficiency and bandwidth effectiveness of the system.
The novel application of ....etc

ABSTRACT
Drag is a mechanical force generated by a solid object moving through a fluid. For drag to be generated, the solid body must be in contact with the fluid. Drag is generated by the difference in velocity between the solid object and the fluid. Drag acts in the direction opposite to the direction of motion of the body.
Microbubbles is a drag reduction device that reduces skin friction of a solid body moving in water by injecting small bubbles into the turbulent boundary layer developing on the s ....etc

Nanoelectronics refer to the use of nanotechnology on electronic components, especially transistors. Although the term nanotechnology is generally defined as utilizing technology less than 100nm in size, nanoelectronics often refer to transistor devices that are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. As a result, present transistors (such as CMOS90 from TSMC or Pentium 4 Processors from Intel) do not fall under this category, even though these devices are manufactured under 90nm ....etc

The Impact of Social, Economic, Political and Geological factors on the building of the Humber Bridge
The River Humber forms the boundary between Lincolnshire to the south, and East Yorkshire to the north. Historically, its broad waters have encouraged significant cultural and economic divisions, while at the same time people have always found ways to cross it. This essay explores some of the reasons as to why this structure has been at the centre of so many controversies.
A brief history of the river crossings[ ....etc
