We have investigated the dynamics of superfluid phase slippage in an array of apertures. The magnitude of the dissipative phase slips shows that they occur simultaneously in all the apertures when the temperature is near T!−T#10 mK and subsequently lose their simultaneity as the temperature is lowered. We describe three experiments to probe the mechanisms underlying the synchronous behavior. Th...

We give a survey on double-loop networks with emphasis on new development since the surveys in 1986, 1991 and 1995. c © 2001 Elsevier Science B.V. All rights reserved.

Multi-phase machines are considered serious contenders as compared to the three phase machines for variable applications in generating mode. This paper presents the transient performance analysis of a multi-phase induction machine operating in six-phase mode for power generation. In this paper the simulation and experimental analysis of a six-phase machine in generating mode have been made. The...

As eGovernment is gaining popularity in administrations, business and with citizen, issues about the course of its evolution take center stage. This evolution is generally seen as a four-step process: presence phase, interaction phase, transaction phase and transformation phase. To date few countries have made a significant progress in the last transformation phase whose goal is to integrate se...

We investigate the relation between measurements and the physical observables for vacuum spacetimes with compact spatial surfaces in (2+1)-gravity with vanishing cosmological constant. By considering an observer who emits lightrays that return to him at a later time, we obtain explicit expressions for several measurable quantities as functions on the physical phase space of the theory: the eige...

We present here an analytical phase noise model of phased-locked loop for frequency synthesizer and its simulation in GHz frequency range. The noise model has been derived and simulated considering two different filter sections in the loop of the phased-locked loop model, namely: (i) active lag-lead filter and (ii) standard feedback approach. The noise transfer functions of the phased-locked lo...

A novel three-phase phase-locked loop solution is proposed based on D-Q transformation aiming at the AC-DC rectifier with high efficiency and high power factor. The phase-locked loop is implemented digitally using the Xilinx blockset integrated with Matlab/Simulink. The three-phase digital phase-locked loop (TDPLL) is elaborately designed with the parameters defined in detail. The AC-DC convert...
