Current authentication systems suffer from many weaknesses. Textual passwords are commonly used; however, users do not follow their requirements. Users tend to choose meaningful words fro...
Domestic refrigerators annually consume approximately 17,500 metric tons of traditional refrigerants such as Chlorofluorocarbon (CFC) and Hydroflourocarbon (HFC) which contribute to very high Ozone...
The performance of Stirling engines meets the demands of the efficient use of energy and environmental security and therefore they are the subject of much curren...
In this century, it is believed that crude oil and petroleum products will become very scarce and costly. Day-to-day, fuel economy of engines is getting improved and will continue to improve. Howev...
Microgrippers are typical MEMS devices used to pick, hold and transport micro-objects. Microgrippers are widely used in the field of micro-assembly, micro-surgery and manipulation of micro-particle...
A prefabricated structure or building is a structure that has several factory built components that are assembled on a site. These pre-made components can consist of panels, modules or transportabl...
A GPU is a microprocessor that has been designed specifically for the processing of 3D graphics. The processor is built with integrated transform, lighting, triangle setup/clipping, and rendering engines, capable of handling millions of math.
Helicopters are the most versatile flying machines in existence today. This versatility gives the pilot complete access to three-dimensional space in a way that no airplane can due to aerodynamics....
Magnetic nanocomposites comprised of nano-sized magnetic crystals embedded in an amorphous matrix have been shown to have excellent soft magnetic properties. In particular, amorphous and nano cryst...
