Dans de nombreuses applications telles que la vidéosurveillance, la détection de personnes est un élément clé. Habituellement, une boîte englobante contenant une personne est extraite. Cependant, une segmentation plus précise de la silhouette peut s'avérer nécessaire. Pour ce faire, nous proposons une stratégie complète de segmentation des personne...
Cet article vise à promouvoir le projet EVEREST (Évaluation des pERformances des systèmes vidÉo pour la Sécurité des Transports guidés en montagne) dont la finalité consiste, à évaluer, lors d'un challenge qui sera organisé en 2020, les performances des systèmes à base d'analyse d'images proposés par des participants, à détecter des comportements p...
In low- and middle-income countries, the management of fecal sludge from on-site sanitation systems has received little attention over many decades, resulting in insufficient or missing regulations to guide investments and management options. To address this gap, this report examines existing and emerging guidelines and regulations for fecal sludge...
La présente communication vise à rendre compte de l'utilisation et de la mise en place d'une triangulation des méthodes lors d'une intervention ergonomique en binôme. L'objectif de l'étude présentée est d'identifier et de proposer une méthodologie pour l'étude de l'impact de l'information voyageurs (IV) sur l'activité des voyageurs. Elle est recuei...
Polyether-block-amide (Pebax)/glycerol triacetate (GTA) blend membranes with various compositions were prepared with a solution-casting method. The gas-separation performance, thermal stability, and storage stability of the prepared membranes were investigated at different pressures and temperatures. The Arrhenius equation was used to describe the ...

The unsteady conjugate mass/heat transfer from/to a prolate droplet suspended in uniaxial extensional creeping flow was numerically investigated. Based on the Stokes velocity field of a prolate droplet at small Reynolds numbers, a numerical algorithm combined with the finite difference method, the concentration transformation method and the level s...

Because of tunable bandgap and high carrier mobility, ternary III-V nanowires (NWs) have demonstrated enormous potential for advanced applications. However, the synthesis of large- scale and highly-crystalline InxGa1-xSb NWs is still a challenge. Here, we achieve high-density and crystalline stoichiometric InxGa1-xSb (0.09 -orientation via chemical...
