STARNET is a broadband backbone optical wavelength-division multiplexing (WDM) local area network (LAN). Based on a physical passive star topology, STARNET offers all users two logical subnetworks: a high-speed reconfigurable packet-switched data subnetwork and a moderate-speed fix-tuned packet-switched control subnetwork. Thus, STARNET supports traffic(More)
The aim of this paper is to maximize the overall exergy efficiency of single channel photovoltaic thermal module. The solar panel (PV module) generally gives electrical efficiency in the range of 7% to 12%, the rest energy being dissipated in the form of heat losses. To recover thermal energy from the module photovoltaic thermal system has been simulated.(More)
We obtain a network traffic model for real-time MPEG-II encoded digital video by analyzing video stream samples from real-time encoders from NUKO Information Systems. MPEG-II sample streams include a resolution intensive movie, City of Joy, an action intensive movie, Aliens, a luminance intensive (black and white) movie, Road To Utopia, and a chrominance(More)
In this paper effort has been made to optimize the overall electrical energy efficiency of a single pass unglazed PVT system. To accomplish this, the design parameter of the presented model has been optimized using an evolutionary algorithm. The equations relating to the system have been derived and the parameters influencing the overall electrical energy(More)
The work is carried out in two ways; one is the overall exergy efficiency of glazed photovoltaic thermal (PVT) module which is optimized with soft computing technique. Evolutionary algorithm is used as a computing techniques in this work. The overall exergy efficiency is considered as the objective function while the optimization is carried out. Secondly,(More)
This paper presents application of parametric techniques (Estimation of signal parameter by rotational invariance techniques (ESPRIT), Root multiple signal classification (Root MUSIC)) for the estimation of harmonics/inter harmonics produced by wind generator under constant, variable rotor speed, load imbalance. Accuracy of estimation by parametric(More)
