Abstract:
The composing semiconductors became the support privileged of information and the communication, in particular grace to the faster development of Internet, for the systems of telecommunications to high debit, some components are necessary. It is for this reason that of the alternative structures have been proposed: the IV-IV heterostructures or III-V. The most effective components in this domain are the field effect transistors (High Electron Mobility Transistor: HEMT) on IIIV substratum. The present work is dedicated to the contribution to the development of a numeric physical model which bas

Abstract:
In aerated lagoons and even more in stabilization ponds the specific power (W/m3) is not high enough to maintain all the suspended solids in suspension. Some part of the suspended solids (including biomass) settles directly into the reactor and not in the final settling pond. The gradual accumulation of those sediments on the pond bottom affects performance by reducing the pond volume and shortening the Hydraulic Residence Time. However, the role played by these deposits is not restricted to such a physical effect. Far from being inert sediments they are also an important oxygen sink that must

Abstract:
Sodium cooled fast neutron reactors (SFR) are one of the selected reactor concepts in the framework of the Generation IV International Forum. In this concept, unprotected loss of cooling flow transients (ULOF), for which the non-triggering of backup systems is postulated, are regarded as potential initiators of core melting accidents. During an ULOF transient, spatial distributions of fuel, structure and sodium temperatures are affected by the core cooling flow decrease, which will modify the spatial and energy distribution of neutron in the core due to the spatial competition of neutron feedb

Abstract:
The properties of polylactic acid (PLA) filaments have not yet been analysed in detail, and they are strongly affected by the extrusion process used in some additive manufacturing systems. Here we present the mechanical, thermal, physical, and fractographical properties of an extruded filament (not the bulk material or scaffolds), the basic building block of any PLA structure printed via material extrusion. This research aims to create a reference point for the modelisation of additively manufactured structures via extrusion processes, as the main building block is characterised in detail for

Abstract:
This work of applied mathematics with interfaces in bio-physics focuses on the shape identification and numerical modelisation of a single red blood cell shape. The purpose of this work is to provide a quantitative method for interpreting experimental observations of the red blood cell shape under microscopy. In this paper we give a new formulation based on classical theory of geometric shape minimization which assumes that the curvature energy with additional constraints controls the shape of the red blood cell. To minimize this energy under volume and area constraints, we propose a new hybri

La technologie sans fil est un catalyseur clé des promesses de l’industrie 4.0 (fabrication intelligente). En tant que telle, la technologie sans fil sera adoptée comme mode de communication principal au sein de l’usine en général et dans les unités de production en particulier. La communication des unités de production en usine a des exigences particulières en matière de latence, de fiabilité, d’échelle et de sécurité qui doivent d’abord être satisfaites par la technologie de communication sans fil utilisée.

Abstract:
L'apprentissage moteur en tant que mécanisme de récupération est supposé être un cadre qui a guidé les principes de la thérapie physique et qui, depuis l'avènement de la robotique, fait de même pour les dispositifs de réadaptation. Le processus de réadaptation représente l'intersection de nombreuses facettes interconnectées qui co-interagissent pour produire des mouvements récupérés. L'utilisation de la technologie présente de nombreux avantages tout en contribuant à la complexité du phénomène en question.

Dans ce travail, nous développons un cadre de calcul dédié à la simulation d'écoulements à plusieurs fluides. Nous présentons des validations et vérifications de ces méthodes sur des problèmes de capture d'interfaces et de simulations de bulles visqueuses. Nous montrons ensuite que ce cadre de calcul est adapté à la simulation d'objet rigides en écoulement. Puis, nous étendons ces méthodes à la simulation d'objets déformables simulant le comportement des globules rouges : les vésicules. Nous validons aussi ces simulations.

Ce travail se situe dans le domaine de la synthèse d’images par ordinateur et de l’animation par modèles physiques. La modélisation et la visualisation d’un objet physique suppose un travail sur la forme, le mouvement et l’image. Plus cet objet de référence est déformable et plus la relation entre ces trois entités est complexe. Dans ce travail, nous étudions cette relation et nous déterminons dans quelles conditions le comportement (forme, mouvement, image) des objets peut être représenté par des modèles autonomes (modélisation multi-échelles) et découplés (habillage).

Abstract:
This article presents a causal, forward looking approach for the hybrid electric vehicle where the typical performance engine map representation has been modified. The need for a more physical model of the power stroke process has been fulfilled with “the filling and emptying” method. The thermodynamic states in the intake and exhaust systems are calculated, while the in-cylinder process is still based on the engine fuel consumption map as a calibrated data. Comparisons with the conventional model are established, most important is the response of the engine torque under the load demand. This
