Retro-nasal aroma release is correlated with variations in the in-mouth air cavity volume after empty deglutition.
2012
International audience; We hypothesized that interindividual differences in motor activities during chewing and/or swallowing were determining factors for the transfer of volatile aroma from the in-mouth air cavity (IMAC) toward the olfactory mucosa. In our first experiment, we looked for changes in IMAC volume after saliva deglutition in 12 healthy subjects. The mean IMAC volume was measured after empty deglutition using an acoustic pharyngometer device. Based on the time course of the IMAC volume after swallowing, we discerned two groups of subjects. The first group displayed a small, constant IMAC volume (2.26 mL ±0.62) that corresponded to a high tongue position. The second group displa…
The Recomposition of Bureaucratic Forms in Territorial Development. Territorial Engineering and Intermediation in Project Territories
2013
L’ingénierie territoriale mobilise un répertoire de savoirs et d’objets intermédiaires au cœur du processus de création territoriale. Cet équipement cognitif est nécessaire à la cohésion de l’action publique multiniveaux au sein du territoire de projet. Dans ce contexte, bien que les modalités de gestion des contrats d’action publique ne dénaturent par la fonction médiatrice de ce répertoire, elles sont standardisées par les forces de l’isomorphisme institutionnel. L’ingénierie territoriale se bureaucratisant, elle administre des procédures qui font des territoires des segments d’exécution d’une politique définie indépendamment des enjeux territoriaux. At the heart of territorial processing…
10 situations pédagogiques pour enseigner l’élevage de précision
2022
Le développement de l’ère numérique est en marche en agriculture, dans le cadre de l’élevage de précision en particulier. Ses enjeux sont immenses sur le plan professionnel, ils irriguent forcément le secteur de la formation.Cet ouvrage permet d'aborder l'élevage de précision dans l'enseignement agricole à partir, tout d'abord, d'exemples emblématiques de tâches zootechniques s'appuyant sur plusieurs espèces animales. Ces exemples font l'objet de la première partie de l'ouvrage, consacrée aux aspects biologiques et technologiques : il s'agit, à travers eux, de faire le lien entre la problématique zootechnique et les possibilités de monitoring en diversifiant les exemples de capteurs/technol…
Distinguishing between two crus : as easy as picking the right side ? : Effect of expertise on conceptual and perceptual representations of Beaujolai…
2017
L’expertise a été étudiée en psychologie cognitive afin de comprendre les mécanismes psychologiques et les compétences intervenant dans différents domaines d’expertise. Dans le domaine du vin, les quelques études menées suggèrent que les experts organiseraient leurs connaissances autour de « prototypes » de couleur ou de cépage. L’objectif général de cette thèse visait à répondre aux questionnements théoriques concernant les représentations des vins d’experts et de novices, ainsi qu’aux questionnements de la filière concernant les perceptions des vins du Beaujolais. Pour cela, l’effet de l’expertise sur les représentations des vins a été évalué en comparant les performances de trois panels …
Knowledge engineering and semantic formalism of symbolic relations. From medieval network to web 3.0
2020
A search has always been at the center of human concerns, the one of conditions and means to represent, to control well, and to communicate effectively with his environment. While technological advances and electronic gadgets such as smartphones, the Web, and online social networks currently allow addressing this concern, it has not always been the case. Our works in this thesis treat medieval documents considered as a medium of communication and as a model of the social network in the Middle Ages. These documents are called medieval illuminations. They were luxurious paintings used in that time to represent the environment and ideal world for elites such as prince, duke, etc. Those paintin…
Adapting to Dynamic LEO-B5G Systems : Meta-Critic Learning Based Efficient Resource Scheduling
2022
Low earth orbit (LEO) satellite-assisted communications have been considered as one of key elements in beyond 5G systems to provide wide coverage and cost-efficient data services. Such dynamic space-terrestrial topologies impose exponential increase in the degrees of freedom in network management. In this paper, we address two practical issues for an over-loaded LEO-terrestrial system. The first challenge is how to efficiently schedule resources to serve the massive number of connected users, such that more data and users can be delivered/served. The second challenge is how to make the algorithmic solution more resilient in adapting to dynamic wireless environments.To address them, we first…
Sensor Fusion Combining 3-D and 2-D for Depth Data Enhancement
2012
Time-of-Flight (ToF) cameras are known to be cost-efficient 3-D sensing systems capable of providing full scene depth information at a high frame rate. Among many other advantages, ToF cameras are able to provide distance information regardless of the illumination conditions and with no texture dependency, which makes them very suitable for computer vision and robotic applications where reliable distance measurements are required. However, the resolution of the given depth maps is far below the resolution given by standard 2-D video cameras which, indeed, restricts the use of ToF cameras in real applications such as those for safety and surveillance. In this thesis, we therefore investigate…
When the nose must remain responsive: glutathione conjugation of the mammary pheromone in the newborn rabbit
2014
In insects, xenobiotic-metabolizing enzymes were demonstrated to regulate pheromones inactivation, clearing them from the olfactory periphery and keeping receptors ready for stimulation renewal. Here, we investigate whether similar processes could occur in mammals, focusing on the pheromonal communication between female rabbits and their newborns. Lactating rabbits emit in their milk a volatile aldehyde, 2-methylbut-2-enal, that elicits searching-grasping in neonates; called the mammary pheromone (MP), it is critical for pups which are constrained to find nipples within the 5 min of daily nursing. For newborns, it is thus essential to remain sensitive to this odorant during the whole nursin…
Interaction peripheral device capable of controlling an element for touching and grasping multidimensional virtual objects
2015
An interaction peripheral device capable of controlling an element for touching and grasping multidimensional virtual objects, including at least two interaction modules, each interaction module being intended to be actuated by a finger of an operator and including a control sensor allowing control of displacement, according to a predetermined number of degrees of freedom, of a portion of the element for touching and grasping virtual objects by bending/extending and/or adduction/abduction displacement of the finger of the operator, and a vibrator able to emit a vibration upon touching and/or letting go of a virtual object by a portion of said element for touching and grasping virtual object…
Une architecture générique de Systèmes de recommandation de combinaison d'items : application au domaine du tourisme
2011
This thesis gives a generalization of the recommendation principle of recommender systems. Instead of considering a recommendation as an item, it is considered as a combination of several items following a given pattern. A recommendation of a unique item is then a particular case of this type of recommendation. The proposed recommender system framework is based on an architecture derived from work in adaptive hypermedia systems. Three layers are defined: a semantic layer, a user layer and an intelligence layer. The semantic layer consists of two sub-layers, a sub-layer modeling the content according to the general knowledge of the domain and a sub-layer modeling the content according to the…
