Multiple Structured Light-Based Depth Sensors for Human Motion Analysis: A Review

2012

Human motion analysis is an increasingly important active research domain with various applications in surveillance, human-machine interaction and human posture analysis. The recent developments in depth sensor technology, especially with the release of the Kinect device, have attracted significant attention to the question of how to take advantage of this technology in order to achieve accurate motion tracking and action detection in marker-less approaches. In this paper, we review the benefits and limitations deriving from the adoption of structured light-based depth sensors in human motion analysis applications. Surveying the relevant literature, we have identified in calibration, interf…

The Large Area Detector of LOFT: the Large Observatory for X-ray Timing

2014

LOFT (Large Observatory for X-ray Timing) is one of the five candidates that were considered by ESA as an M3 mission (with launch in 2022-2024) and has been studied during an extensive assessment phase. It is specifically designed to perform fast X-ray timing and probe the status of the matter near black holes and neutron stars. Its pointed instrument is the Large Area Detector (LAD), a 10 m 2 -class instrument operating in the 2-30keV range, which holds the capability to revolutionise studies of variability from X-ray sources on the millisecond time scales. The LAD instrument has now completed the assessment phase but was not down-selected for launch. However, during the assessment, most o…

Extreme statistics in Raman fiber amplifiers : influence of pump depletion and dispersion

2010

OSA 2010 NonLinear Photonics Best Student Poster Award; International audience; We experimentally and theoretically investigate the influence of pump depletion effects on extreme statistics observed in fiber Raman amplifiers. We also report on the impact of the dispersion of the fiber.

Theoretical study of microfiber resonator devices exploiting a phase shift

2008

Phase shifts within microfiber resonators can be exploited to demonstrate compact and fast-responding devices. Two examples, a sensor and a bistable device, where the origins of the phase shift are fundamentally different, are investigated. In the sensor the phase change originates from the change of refractive index of the medium surrounding the microfiber ring. This is a linear mechanism which translates into a change of resonance wavelength. Calculations of a silica microfiber ring immersed in an aqueous solution and operating at a wavelength of 1550 nm show that with a fiber 550 nm in diameter the sensitivity approaches a maximal value of about 1137 nm/RIU. In contrast to the sensitivit…

Treated wastewaters discharged from wastewater treatment plants (WWTP) and livestock effluents are the main sources of contamination of aquatic environments and of agricultural soils by human and animal fecal micro-organisms. Contaminated waters, especially bathing waters, may present a sanitary risk for humans if the concentrations of fecal micro-organisms are high, thus indicating the potential presence of pathogenic and/or antibiotic resistant strains. Soils and crops also can be contaminated by these micro-organisms when treated wastewaters are used to irrigate cultivated soils. Consequently, microbiological quality controls are mandatory for bathing waters and treated wastewaters to ma…

Les effets de l'éducation sensorielle sur les préférences et les comportements alimentaires des enfants

2010

National audience; Ce dossier réalisé en partenariat avec le Centre européen des produits de l’enfant traite de la responsabilité éducative des adultes et de l’éducation de l’enfant futur citoyen consommateur.Il consacre une large place à la mise en place des politiques et des pratiques existantes dans plusieurs pays d’Europe et au Canada. Son ambition est de participer aux débats d’idées et de donner des repères sur les enjeux que représentent pour l’avenir de l’humanité, l’éducation et la consommation. Ce dossier est coordonné par Valérie-Inès de La Ville Professeur de Sciences de Gestion, Directrice Centre Européen des Produits de l’Enfant et Christian Gautellier Directeur des publicatio…

Gros plan sur ChemoSens, R&D et expertise en analyses physico-chimique et sensorielle. Une plate-forme du Centre des Sciences du Goût et de l'Aliment…

2016

ChemoSens est une plate-forme de recherche publique du Centre des Sciences du Goût et de l'Alimentation (CSGA, unité mixte de recherche CNRS - INRA - Université Bourgogne Franche-Comté). Son originalité repose sur l'utilisation combinée de la chimie et de l'analyse sensorielle pour développer de nouvelles approches de caractérisation des aliments et du comportement alimentaire.
