This paper proposes a novel three-phase nine-switch ac/ac converter topology. This converter features sinusoidal inputs and outputs, unity input power factor, and more importantly , low manufacturing cost due to its reduced number of active switches. The operating principle of the converter is elaborated; its modulation schemes are discussed. Simulated(More)
A series of 4-{4-[2-(4-(2-substitutedquinoxalin-3-yl)piperazin-1-yl)ethyl] phenyl} thiazoles were synthesized in an effort to prepare novel atypical antipsychotic agents. The compounds were designed, synthesized, and characterized by spectral data (IR, 1H NMR, and MS) and the purity was ascertained by microanalysis. The D2 and 5-HT2A affinity of the(More)
In this article an efficient routing protocol has been identified for real time and non – real time applications.The MS movement direction prediction (MMDP) based MS scanning is implemented to overcome the mobile WiMAX handover issues. Here the authors have used the MMDP method to reduce the number of scanning's required for the handover instead of scanning(More)
This paper deals with estimation of target kinematics from radar measurements through offline processing of the trajectory data obtained from a ground based monopulse tracking radar. Being recursive the two popular filters αβγ and kalman filters are adopted. Simulations are carried out for these filters with three different trajectories(More)
