During the turn-on and turn-off switching processes, power converters have to withstand high voltage and current, leading to high switching losses and stresses. The invention is a passive lossless snubber cell with minimum stress and wide soft-switching range. The energy reset / recirculation proces.....

The thin film transistors (TFT) have been built on patterned flexible bilayer acid/metal oxide dielectrics polymer substrate by solution process. Based on this TFT technology, RFID tags and amine sensors have been fabricated with low cost using inexpensive molecular materials. Fabrication through so.....

The invention relates to an improved method for storing hydrogen in single-walled carbon nanotubes. Carbon nanotubes are dipped in hydrogen gas for absorption. The size of carbon nanotubes to be used depends on the density of hydrogen molecules, and generally, nanotubes of diameters from 0.5 to 1.2 .....

The universal rate control scheme can be adapted to various transuding purposes including real-time video transcoding. A new rate-distortion (RD) model is established for better characterization of the real RD feature of transcoding. A level-window rate control (WRC) algorithm is proposed for provid.....
