Technical education in classical fields like electrical engineering is confronted in western countries with on one side a high demand for engineers coming from industry and on the other side by the reduced interest from younger generation, whose interest i ...
At the present time, variable-message signs (VMS) and variable speed-limit signs are in frequent use for traffic control, especially along urban motorways. The Lausanne by-pass is partially equipped with these and should be fully equipped in the near futur ...
The present paper describes the modelling and the prediction of the steady-state or transient behaviour of different modern variable-speed drives and electrical networks. The necessity of a performant numerical simulation tool in order to guarantee an opti ...
