Within the meaning of the European Directive 2002/49/EC, noise assessment relies on the production of strategic noise maps for large cities that are entirely based on numerical simulations. The relevancy of these maps is debatable owing to unquantified uncertainties and to the consideration of a limited number of sound sources. Noise observatories ...

Surface-roughness caused by the residue of an ablative Thermal Protection System (TPS) can alter the turbulence level and surface heating rates on a hypersonic re-entry capsule. Large-scale surface-roughness that could represent an ablated TPS, was introduced over the forebody of a 120 degrees apex angle blunt cone, in order to test for its influen...
In this paper, the recent efforts for the qualification of the thermal-hydraulic system code CATHARE for nuclear research reactors are presented. Even if the code has been extensively validated for commercial pressurized water reactors, additional work was needed due to the unique design and operating conditions of research reactors. In fact, in th...

Ultrasonic array imaging is widely used to provide high quality defect detection and characterization. However, the current imaging techniques are poor at detecting and characterizing defects near a surface facing the array, as the signal scattered from the defect and the strong reflection from the planar backwall will overlap in both time and freq...

Loin de disparaître du monde du travail, les risques psychosociaux continuent d’inquiéter au sein des organisations. Leur taux est toujours aussi élevé et leurs effets néfastes pour la santé. Il est néanmoins possible d’agir en prévention pour isoler ces risques et les réduire. L’analyse de situations à forte charge émotionnelle, à partir de l’obse...
