It is a trend for the large hydropower bases to transport electricity consuming center with High Voltage Direct Current (HVDC) transmission lines. The fault of HVDC has great significance impact on units in islanding sending AC grid. In this paper, hybrid simulation system established analyze dynamic characteristic system. based Real Time Digital Simulator (RTDS) and Signal Processor (DSP). ele...

Electromagnetic transients (EMT) is the most accurate, but computationally expensive method of analyzing power system phenomena. Thereby, interconnecting several real-time simulators can unlock scalability and coverage, leads to a number new challenges, mainly in time synchronization, numerical stability, accuracy quantification. This study presents such cosimulation, based on digital (DRTS), c...

in this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent hamiltonians. we drive the time-dependent recursion relations for the renormalized tight-binding hamiltonian by decimating selective sites of lattice iteratively. the formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

We first demonstrate theoretically and experimentally that electromagnetic resonators with high quality factors (Q) can be used to transfer power efficiently over distances substantially larger than the characteristic dimensions of the resonators by operating in a so-called "strongly coupled" regime. We next generalize the notion of strongly coupled resonances to a system comprising one power s...

Electromagnetic (EM) aftereffects have been reported following near-death experiences (NDEs). These effects include both (a) EM actions, apparent actions by the individual on the surrounding EM environment, and (b) EM reactions, apparent reactions of the individual to the EM environment. This study investigated EM aftereffects among 216 NDErs, 54 persons who had been close to death without NDEs...

In this article, a systematic and comprehensive approach based on finite element analysis analytical modeling for studying static pull-in phenomena in hybrid levitation microactuators is presented. A model of electromagnetic the Lagrangian formalism formulated developed as result recent progress calculation mutual inductance between filament loops. particular, allows us to calculate accurately ...

The paper deals with finite element model for analysis of electromagnetic forming process of thin metallic sheets. The investigation starts with the FLUX simulation of transient electromagnetic field phenomena, continues with a transient structural analysis using ANSYS Structural under loads previously evaluated and ends with an ANSYS Multiphysics fully coupled analysis. The paper emphasizes th...
