This paper describes a new on line web course on Electromagnetics for Engineering, designed by the authors and delivered at the Technical University of Cluj-Napoca (TUCN), Romania. The main results presented are related to the design of the on line course components: graphical interfaces, dynamic web pages created for glossary of terms and virtual library,(More)
A numerical approach based on the extended finite element method efficiency and level set method flexibility is proposed in the present paper for the shape optimization of a switched reluctance motor pole. Using the extended finite element method as an analysis tool, an unstructured and non-conform mesh to the moving interfaces is generated only once, at(More)
The paper presents the structure and the performance of signal processing algorithms that simulate natural room reverberation. It deals with three digital complete artificial reverberators, built up of Schroeder’s early reverberator and a late reverberator built with all-pass filters: Schroeder’s, Gardner’s or absorbent all-pass reverberator. For each of(More)
The paper emphasize the results of the first systematic electromagnetic field measurements performed in high and very high voltage substations belonging to the Romanian national power grid in order to face the requirements of the EU directives regarding the human exposure to the electromagnetic fields. In the first part of the paper, the experimental field(More)
