This paper presents photovoltaic (PV) grid-connected power conditioning systems based on Z-source inverter. Using Z-source network, the system can work within a range of PV array output voltage wider than that of the conventional boost converter. It allows the use of the shoot-through switching state for boosting the input voltage, compensates dead-time effect which causes serious output voltage distortions...
Fractal image compression is a novel technique in the field of image compression; it is based on affine contractive transforms and utilizes the existence of self-symmetry in the image. This technique has grabbed much attention in recent years because of manifold advantages, very high compression ratio, high decompression speed, high bit-rate and resolution independence. Since 1990 a lot of techniques...
It is anticipated that wearable wireless sensors in body area network (BAN) will increase the functionality of lifestyle and health care devices to gradually match the needs of society by year 2010 and people will carry their personal Body Area Network. The applications in areas like lifestyle, assisted living, sports, entertainment functionalities, toxic levels in the lungs of a Fire-Fighter, radiation...
Wearable health monitoring is novel information technology that will be able to support early detection of abnormal conditions and prevention of its serious consequences. It is useful in areas like lifestyle, assisted living, sports and entertainment functionalities, toxic levels in the lungs of a fire-fighter, radiation exposure in war zones etc. Real time stress monitoring of fighter pilots through...
