The most popular means of depression treatment are psychotherapy, antidepressant medication and recently adopted transcranial magnetic stimulation (TMS) of the human brain. To overcome their disadvantages we are investigating an application of low-field magnetic stimulation (LFMS) to depression treatment. The 3D electromagnetic model of LFMS has been developed. It employs 8 small coils disposed ...

A simple magnetic circuit consisting of ferromagnetic core material, air gap, permanent magnets and current coils can be used to form magnetic actuators, motors etc. devices. In this work the current coils are not used to generate working magnetic field, but just to switch magnetic flux created by permanent magnets in necessary direction. Analytical and numerical (Finite Element Model, ...

A eletroquimioterapia é um tratamento de câncer que utiliza a combinação de agentes quimioterápicos e campos elétricos. A base teórica por trás dessa aplicação é a eletroporação. Esse fenômeno biológico consiste na abertura de poros na membrana celular devido à aplicação de pulsos elétricos. Este trabalho analisa o comportamento do campo elétrico gerado por pulsos elétricos aplicados em ...

In this presentation it is shown how an axially symmetric coil can be simulated in a non-symmetric environment. A rotationally symmetric coil can be simulated by using a 2D model. Doing so the serial equivalent resistance of the coil is obtained among other results. The influence of the environment needs to be simulated with a 3D model. In this model the single wires of the coil are replaced by ...

Adaptive Optics is common sense, since many people use digital cameras with electromechanical iris actors on elastic autofocus lenses. This project tries to create a COMSOL Multiphysics based mathematical model of adaptive optics with electrostatically induced deformation of dielectric gels. Upper and lower sides of a lens (dielectric conductive gel) are coated by transparent conductive films, i ...

Electric field distribution along an insulator surface is of prime importance for the long term performance of insulators. In this paper electric field and potential distribution along a standard 33 kV polymeric insulator were investigated under different pollution conditions. Effect of voltage type and polarity on the electric field and potential distribution under contaminated conditions were ...

摘要：在太空高能带电粒子作用下，航天器上存在绝缘介质深层充电的危险。介质内沉积电荷导致局部出现强电场（达到107V/m），有可能造成介质击穿放电。一方面，充电过程与介质电导率密切相关，而电导率受温度影响显著，另一方面，介质中的通电导体发热会影响介质的局部温度，于是有必要综合考虑介质中电场与热场的耦合变化过程。对此，我们建立了考虑电场与热场耦合变化的介质深层充电模型，并采用 COMSOL Multiphysics® 软件，实现了数值求解。结果表明，在一定的空间辐射环境下，考虑热场是十分重要的，热导率会对充电结果产生不可忽视的影响。该模型有利于多因素作用下的航天器介质深层充电评估计算。 1. 引言： 近些年，卫星充放电效应得到了广泛关注和研究[1, 2]。太空高能电子会射入航天器绝缘介质中，因为该介质极低电导率（10-15S/m量级），使得内部沉积电荷难以泄放 ...

Cogging torque in permanent magnet motors and generators is characterized by a torque ripple. These torque fluctuations cause vibrations, noise and speed fluctuations. This paper presents finite element (FE) analyses results that show a previously unaddressed low frequency modulation of cogging torque ripple. The paper resulted in an analytical formulation of cogging torque with low frequency ...

Prototype Fast Breeder Reactor (PFBR) is a 500MWe, sodium cooled, pool type, mixed oxide (MOX) fuelled reactor. Sodium flow measurement in various loops of the reactor is of prime importance from the operational and safety aspects. To measure the flow of electrically conducting sodium in large secondary circuit pipes, probe type permanent magnet flowmeters (PTFM) are used. PTFM works on the ...
