| A method for reducing the roll of a ship consists in placing a tank whose liquid content is animated by free surface sloshing motions. The dynamic coupling with the vessel is studied experimentally at reduced model in a test tank. Numerical modeling under perfect fluid and viscous fluid assumptions make it possible to approach the measured responses. |

| We investigate experimentally the time evolution of the wetted surface during the lifting of a body initially floating at the water surface. This phenomenon is referred to as the water exit problem. The water exit experiments were conducted with transparent (PMMA) mock-ups of two different shapes: a circular disc and a square flat plate. Two different lighting systems were used to diffuse light in the mock-up material: a central high-power LED light normal to the surface and an edge-lighting system featuring an array of LED lights. These setups make it possible to illuminate the contact line, which delimits the surface of contact between the mock-up and the water. The characteristic size of the mock-ups is about 20 cm and the acceleration of the mock-up... |

| Underwater imagery is increasingly used as an effective and repeatable method to monitor benthic ecosystems. Nevertheless, extracting ecologically relevant information from a large amount of raw images remains a time-consuming and somewhat laborious challenge. Thus, underwater imagery processing needs to strike a compromise between time-efficient image annotation and accuracy in quantifying benthic community composition. Designing and implementing robust image sampling and image annotation protocols are therefore critical to rationally address these trade-offs between ecological accuracy and processing time. The aim of this study was to develop and to optimize a reliable image scoring strategy based on the point count method using imagery data acquired on... |

| Ces essais se déroulent dans le cadre de la thèse du Dr LODDE sur l’impact d’une plongée sur le corps humain. Suite à un protocole bien défini, des médecins feront divers analyses sur les plongeurs avant et après immersion. 16 plongeurs ont été reçus sur 2 jours : 8 palanquées de 2. Chaque plongeur passe par des examens médicaux avant plongées : EFR, laser doppler, tension, prise de sang. Après une plongée de 40 minutes à 20m, le plongeur recommence les examens. Les médecins seront ainsi en mesure, sur un échantillon de plongeurs désignés (age, sexe, poids, taille différents), de déterminer l’influence d’une immersion sur le corps humain. |
