BACKGROUND The character of ablation processes with high-frequency electrical current is similar in most biological tissues; however, quantitative characteristics are very different. Consequently, mathematical models of the process have a lot of specific aspects. In this study, we developed mathematical model of radiofrequency ablation in liver tissues with experimental validation of model in e...

Magnetic resonance electrical impedance tomography (MREIT) was recently proposed for determining electric field distribution during electroporation in which cell membrane permeability is temporary increased by application of an external high electric field. The method was already successfully applied for reconstruction of electric field distribution in agar phantoms. Before the next step toward...

Acousto-electric interaction signal (AEI signal) resulting from interaction of acoustic pressure wave and electrical current field has received recent attention in biomedical field for detection and registration of bioelectrical current. The signal is very of small value and brings about several challenges when detecting it. Several observations has been done in saline solution and on nerves an...

Long-term demand forecasting presents the first step in planning and developing future generation, transmission and distribution facilities. One of the primary tasks of an electric utility accurately predicts load demand requirements at all times, especially for long-term. Based on the outcome of such forecasts, utilities coordinate their resources to meet the forecasted demand using a least-co...

A three dimensional finite element model of the cut:meous wound stimulated by direct electric current was built by means of the finite element method, As was assumed in part I of this article, the endogenous electrical properties of the injured skin are' beneficial and necessary for a normal course of healing. Therefore, an attempt was made to determine the parameters of transcutaneous electric...

This paper introduces the reader to electric and magnetic fields, particularly those fields produced by electric power systems and other sources using frequencies in the power-frequency range. Electric fields are produced by electric charges; a magnetic field also is produced if these charges are in motion. Electric fields exert forces on other charges; if in motion, these charges will experien...

Forecasting the geomagnetic e ects to technological systems on the ground requires rapid calculations of the electric and magnetic elds produced by the auroral electrojet. The electrojet is often modelled as a line current at a height of 100 km, but in reality it has a nite width and is typically spread over 5◦ or 6◦ of latitude. We show that the width of the electrojet can easily be included i...
