The problem of unbounded uniaxial chiral omega media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are determined. The similar problem of static electric and magnetic current sources with the goal of ...

The proliferation of non-linear and time-variant loads is causing a number of disturbances on the electric network, from a more and more significant distortion of both currents and voltages, to transient disturbances on the supply voltage. In this respect the electric network behaves as an "healthy carrier" of disturbances, so that a disturbance generated by one customer can be distributed to o...

—Large scale electric energy measurement has the problems of big scale of data, difficult of network scheduling and low measurement accuracy. In order to solve the above problems, this paper proposed the electric energy measurement mechanism based on the electromagnetic coupling system and the big data resonant cavity. Firstly, based on the opportunity coupling mechanism, the electromagnetic o...

The authors review the existing physical modalities for treatment of chronic wounds and show the advantages of electric current and electromagnetic field stimulation. Direct currents, low frequency pulsed currents, monophasic high voltage pulses and pulsed electromagnetic fields are compared in respect of their efficiency. Wound healing quantification methods, wound healing dynamics and prognos...

Electric power is the mainstay of a nation’s economy and the lifeline of industrial production and social life. All parameters of an electric grid, especially harmonic parameters, are related to the quality of electricity generated, which guarantees safe operation of electric equipment. Therefore, this design combines a web-based electric grid parameter measurement system with a video-monitorin...

State of health (SOH) of batteries in electric and hybrid vehicles can be observed using some battery parameters. Based on a resistanceecapacitance circuit model of the battery and data obtained from abundant experiments, it was observed that the diffusion capacitance shows great correlation with SOH of a lithium-ion battery. However, accurate measurement of this diffusion capacitance in real t...
