Bentonite from the Birjand area of Iran was characterized by X-ray diffraction, X-ray fluorescence, and Fourier transform infrared spectroscopy. The removal of cadmium from aqueous solution by this bentonite was investigated as a function of conditions such as contact time, metal concentrations, pH, stirring speed, temperature, particle size, and amount of bentonite. The adsorption isotherm was studied...
This paper presents the dynamic voltage restorer based on 13-level Mixed Multi-cell Cascaded Multilevel Inverter. This inverter is based on a new cell obtained from the mixture of the two most popular Multi-cell topologies, Flying Capacitor and Cascaded Multi-cell inverter. The new cell provides a high number of output levels, high modularity, low number of components and low losses. The proposed...
Static synchronous series compensator (SSSC) is a series connected FACTS devices. It is able to providing the reactive power compensation of power system. The SSSC injects a series ac voltage to transmission line through a transformer, which leads or lags the line current by 90??, thus emulating a controllable inductive or capacitive reactance. SSSC can be used to reduce the equivalent line impedance...
Quality-of-Service Multicast routing is a well-known NP-complete problem as constrained Steiner tree problem, which has various real-time multimedia applications in highspeed networks. The bandwidth-delay-constrained least-cost multicast routing algorithms based on Tabu Search are proposed in this paper. These algorithms can improve the search speed, and make a better solution by using one of the...
Multicast routing with quality-of-service constraints is one of the most important problems in computer networks as constrained Steiner tree problem. It is a well-known NP-complete problem, which has various real-time multimedia applications in high-speed networks. In this paper, we propose algorithms to solve the bandwidth-delay-constrained least-cost multicast routing problem based on Tabu search...
