Induction heating is used in many industrial applications to heat electrically conductive materials. The coupled electromagnetic-thermal induction process non-linear general, and for ferromagnetic materials it becomes challenging since both the electromagnetic thermal responses are non-linear. As a result of existing non-linearities, simulating task. In present work, transient finite element so...

Recently, considerable research efforts are focused on the sensorless Induction Motors (IM) control problem. We refer the reader to [12] for a tutorial account on the topic. Indeed, industries concerned by sensorless IM drives are continuously seeking for cost reductions in their products. The main drawback of IM is the mechanical sensor. The use of such direct speed sensor induces additional e...

The definition of the induced emf as the integral over a closed loop of the Lorentz force acting on a unit positive charge leads immediately to a general law for electromagnetic induction phenomena. The general law is applied to three significant cases: moving bar, Faraday’s and Corbino’s disc. This last application illustrates the contribution of the drift velocity of the charges to the induce...

objective: most people experience bone damage and bone disorders during their lifetimes. the use of autografts is a suitable way for injury recovery and healing. mesenchymal stem cells (mscs) are key players in tissue engineering and regenerative medicine. their proliferation potential and multipotent differentiation ability enable mscs to be considered as appropriate cells for therapy and clin...

This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. This paper provides high frequency models ...

Introduction: It is important that biological and health effects from the induction of currents and fields in the body by extremely low frequency (ELF) fields are fully explored to determine the effects produced at the molecular, cellular and organ levels. The objective of this study was to evaluate the intensity of ELF electromagnetic fields and its probable relationship with hematological cha...

Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields-electric displacement field D, magnetic induction field B, and Poynting vector B-are all displaced in a consistent manner. A simple illustration is given of the cloaking of a proscribed volume of space to exclude completely all ...
