Voltage-controlled oscillators (VCO) are one of the most essential building blocks in phase-locked loops and frequency synthesizers, which are required in all data communication and telecommunication systems for generating highly accurate timing reference sources. However, existing VCOs need a suppl.....

Flue gases produced in combustion processes, such as coal-fired power plants, automobiles, smelters, etc., contains huge amount of nitrogen and sulfur oxides, carbon monoxide and particulates. They contribute significantly to atmospheric pollution and some of them are stringently controlled by legis.....

Optical limiting materials show a non-linear transmittance of light, with transmission varying with the intensity of the incident radiation. Transmission is high at normal intensity, but low for intensive beams. Such materials are useful to protect, inter alia, optical elements, sensors, or the huma.....

III-nitride compound semiconductors have the merits of wide band gap, high breakdown field, and large thermal conductivity, which results in well designed AlGaN/GaN heterojunction field-effect transistors. This transistor is capable of high temperature operation, suitable for high temperature integr.....

A significant problem in data networks is that of congestion control, especially at switching nodes which receive incoming data packets from a number of channels, determine the next destination of these incoming packets, and send them to their destinations. Fair Queuing (FQ) is therefore needed to p.....
