In this paper, the major factors that affect performance of wireless power transfer systems, such as coil inner radius and number turns, are discussed. A comparison three shapes covering coreless case, case with ferrite, ferrite aluminum is also carried out. Another proposed by addressing combination different in (WPT)system. The analysis covers coupling coefficient, mutual inductance, self-ind...

We study the symmetries of the two dimensional Heterotic string theory by following the approach of Kinnersley et al for the study of stationary axially-symmetric Einstein-Maxwell equations. We identify the finite dimensional symmetries which are the analogues of the groups G and H ′ for the Einstein-Maxwell equations. We also give the constructions for the infinite number of conserved currents...

In this article we consider an inverse boundary value problem for the timeharmonic Maxwell equations. We show that the electromagnetic material parameters are determined by boundary measurements where part of the boundary data is measured on a possibly very small set. This is an extension of earlier scalar results of BukhgeimUhlmann and Kenig-Sjöstrand-Uhlmann to the Maxwell system. The main co...

The Maxwell Centre, a health-based place of safety (POS) adjacent to a psychiatric hospital, was opened in Gloucestershire in February 2009. It provides a POS for people detained under Sections 135 and 136 of the Mental Health Act 1983 as amended in 2007. Prior to the opening of the Maxwell Centre, police cells were the only designated POSs. To assess the impact of the opening of this new facil...

Desde que James Clerck Maxwell publicou seu brilhante trabalho unificando a eletricidade e magnetismo surgiram, partir de então, inúmeras aplicações práticas do mesmo. Este artigo discute o potencial elétrico bidimensional tridimensional, obtidos da solução equação Laplace, assim como para os campos magnético Helmholtz com condições iniciais específicas. Explicitamos utilização teorema superpos...

In this research, we will seek to design and numerically evaluate a refractive index nano-sensor based on the resonant system with metal insulating waveguide (MIM) that forms wide range of wavelengths. To proposed sensor structure, use two cavities rings different dimensions plasmonic waveguides. After designing examine wavelengths resonators by finite difference method time domain, because dir...

Unsteady flow of an incompressible Maxwell fluid with fractional derivative induced by a sudden moved plate has been studied, where the no-slip assumption between the wall and the fluid is no longer valid. The solutions obtained for the velocity field and shear stress, written in terms of Wright generalized hypergeometric functions pΨq, by using discrete Laplace transform of the sequential frac...

Magnetic pole position detection is the core of closed-loop control system permanent magnet linear synchronous motor (PMLSM), and its estimation accuracy directly affects performance dynamic response speed. In order to solve problem increased error magnetic caused by field distortion at end PMLSM while also considering cost hardware, paper uses four Hall sensors as components adopts an optimize...
