Preeclampsia and intrauterine growth restriction are related to placental insufficiency and constitute a major public health challenge. Significant changes in placental microarchitecture have already been described in these situations, including, for example, increases or decreases in the number of villi ramifications and the presence of fibrin dep...

The analysis of structures partially filled with liquids (liquid-propellant rockets, liquid cooling systems, etc ...) is of the most interest for the industrial domains like transports or aerospace (aircrafts, satellites, rocket launchers, etc ...). Many experimental and computational research have been performed to better understand the behavior o...
In this paper, we consider spectral clustering over data collected by a network of sensors. In this context, the spatial data distribution is not necessarily uniform and can further be affected by sensor noise. This is why we propose a new similarity measure for spectral clustering in sensor networks. This similarity function is derived as the p-va...
Le décret du 7 août 2017 s’appliquant à tous les lieux diffusant des sons amplifiés a présenté un certain nombre de modifications concernant les conditions de diffusion. Le point principal est la limitation du niveau sur 15 minutes à 102 dBA et 118 dBC, en tout endroit accessible au public, que le lieu soit clos ou ouvert. Pour les niveaux m...
De précédentes études ont révélé un effet significatif de la différence interaurale de temps (ITD) lors de la sommation de sonie binaurale, augmentant la sonie de sons purs basses fréquences présentant une disparité temporelle interaurale. Cet effet joue vraisemblablement un rôle dans le phénomène de sonie directionnelle lorsque la sou...

Collisions in musical string instruments play a fundamental role in explaining the sound production in various instruments such as sitars, tanpuras, and electric basses. Contacts occurring during the vibration provide a nonlinear effect which shapes a specific tone due to energy transfers and enriches the hearing experience. As such, they must be c...

— The fundamental and practical problem of passive localization in range and depth, of an acoustic underwater source is addressed, with application to an at-sea experiment. We propose and try a new matching method based on a metric called as Hausdorff distance as a cost-function to be minimized, in order to perform the localization inversion. The d...
The ASTRID project, a French sodium-cooled nuclear reactor of 4th generation, is currently under development by the French Alternative Energies and Atomic Energy Center (CEA). In this project, development of monitoring techniques for a nuclear reactor in operation is identified as an important issue to improve the plant safety. The use of ultrasoni...
