Simulation is a key issue in the design of control electrical systems. Simulation packages using component library, such as PSIM®, are very useful to achieve this goal. The simulation model is thus easily built from the system topology (structural model). ...
Free crest spillways are hydraulically efficient and safe in operation. Since their discharge capacity is directly proportional to the crest length several types have been developed with the purpose to increase the length of the latter. Among these types t ...
Confluences are the nodes of the fluvial network. They are typically characterized by highly heterogeneous conditions that are favorable for a sound fluvial ecosystem, and play a key role in the connectivity of the river system. During the past centuries, ...
The sediment transport capacity of the Avançon river through the city of Bex in Switzerland is limited. During the October 2000 flood event, water levels rose to danger limits. After the flood, the river channel was completely filled with sediments, with a ...
The present study addresses the key issue of linking the chemical speciation to the uptake of priority pollutants Cd(II) and Pb(II) in the wastewater treatment plant effluents, with emphasis on the role of the colloidal organic matter (EfOM). Binding of Cd ...
The sustainable use of reservoirs for irrigation, flood protection, water supply and hydropower may be endangered due to unavoidable reservoir sedimentation. Turbidity currents are the main process for the transport and deposit of sediments in reservoirs, ...
Sediment transport in alpine rivers is responsible for numerous problems related to reservoir sedimentation, river training works and flood protection. These different subjects are often treated locally, even if they are part of a more global solid transpo ...
Streambank erosion is an aspect of flood hazards that has been largely neglected to date due to its complexity. The INTERREG IIIb NWE project « Strategies and Actions for Flood Risk Management » (SAFER) has recognized its importance by including this aspec ...
For recurrent service providers (fast-food, entertainment, medical care,...), retaining loyal customers is obviously a key issue. The customers' loyalty essentially depends on their service satisfaction defined via an ad-hoc utility function. Among several ...
Scale and resolution have long been key issues of geography. In recent years, the rapid development of desktop or Internet Geographic Information Systems (GIS) has forced a more precise consideration of these concepts. This research focuses on fitting the ...
