3. Electromagnetic noise generated in the electrified railway propulsion system
Abstract : The electromagnetic compatibility (EMC) problem in the railway propulsion system is a significant safety issue of high concern. The problems can be caused by any part of the propulsion system as well as any combination of the sub systems. Simulation is a fast economical way to understand the system and to predict the EMC performance. READ MORE

4. Prediction and Optimisation of Traffic Noise. A Study on Noise Barriers and Shielded Areas
Abstract : The main contribution of noise levels in cities is today road traffic. The strongest source for all road vehicles is most often the tyre-road contact. This source position close to the ground is fortunate with respect to secondary noise abatement measures, such as absorbing road surfaces or noise barriers. READ MORE
