This paper deals with a real-world decision-aiding problem for zoning the risk of erosion, total suspended solids emissions, and ecological consequences of their transfers towards the streams. One of these consequences is the decrease of fishes into the streams in agricultural watersheds, because of the clogging of spawning areas. Given the multiple criteria nature of the problem, the originality...
A large-scale field survey was undertaken in the Neste system (South-West France) to investigate the impact of pesticide inputs on the structure of riverine benthic diatom communities. A total of 18 sites in the “Coteaux de Gascogne” study area were sampled during periods of pesticide use over two consecutive years (2005–2006).The typology of the diatoms collected was determined using artificial neural...
Core-less magnetic components have only winding losses and show a much more pronounced size reduction with increasing frequency. Therefore air coils have a size advantage in the MHz range used for energy-storage in switch-mode power supplies. The use of high switching frequencies causes eddy currents in the windings with the consequence of significantly increasing copper losses. The paper describes...
