A universal driving technique for light emitting diodes (LEDs) is presented. The driver can operate with lighting fixtures for fluorescent lamps without requiring the replacement of any type of ballast circuitry or modifying the existing infrastructure of a lighting network. This technology provide.....

Traditional video-on-demand (VoD) is based on the client-server approach. It is expensive and not scalable. In recent years, the Peer-to-Peer approach was first demonstrated to work for live content streaming, and later for VoD streaming as well. Various efforts are working on building a P2P-base.....
