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 ...
The management of a network of existing road bridges involves interventions in order to maintain safety and the priority of these interventions is often determined by safety criteria. During the evaluation of safety, the dynamic effect of traffic actions i ...
Machine-tool axes for high-speed machining make great demands on the mechanical system, the actuators, and the numerical control. They require a high stiffness, a high bandwidth, and a precise motion at maximum speed. Linear motors as direct drives for mac ...
The present work is aimed at finding a decentralized, adaptive solution for intelligent speed limitation that increases highway efficiency. Each segment of the highway is associated with an intelligent agent which can monitor traffic conditions and impose ...

This article describes how a simulation-based evaluation methodology was applied on a variable speed limit signs (VSLS) system designed for a heavily-traveled roadway around Lausanne, Switzerland. Using the MITSIM Laboratory, the evaluation focused on dete ...
Nowadays, multilevel VSIs (Voltage Source Inverter) begin to be widely used in middle and high power installations such as variable speed drives, FACTS (Flexible AC Transmission System) and windformers for example. In these systems, 2 VSIs are put back to ...
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 ...
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 ...
