Local heat transfer measurements and aspect ratio influence during flow boiling in microscale, Ébullition dans les micro canaux : influence du rapport d'aspect sur le transfert thermique local

Sofia Korniliou

Flow boiling in microchannels is a promising technology for cooling of small-scale devices such as electronic chips, power rectifiers, radar arrays, chemical microreactors that require dissipating heat fluxes of several MW m-2 while maintaining constant temperature at the surface. Although flow…, L’ébullition en micros canaux est une technique de refroidissement très prometteuse pour les composants en microélectronique. Ces derniers, de plus en plus miniaturisés, nécessitent souvent la dissipation de densités de flux importantes, pouvant atteindre quelques MW m-2 pour maintenir des…

Stochastic Game Modelling for Distributed Constraint Reasoning with Privacy

Julien Savaux, Julien Vion, Sylvain Piechowiak, René Mandiau, Toshihiro Matsui, Katsutoshi Hirayama, Makoto Yokoo, Shakre Elmane, Marius Silaghi

Privacy has been a major concern for agents in distributed constraint reasoning. In this work, we approach this issue in distributed constraint reasoning by letting agents compromise solution quality for preserving privacy, using utility theory. We formalize privacy in the context of distributed…

A pseudo-transient heat transfer simulation of a continuous casting process, employing the element-free Galerkin method

Juan Carlos Álvarez-Hostos, Alfonso D. Bencomo, Eli Saúl Puchi-Cabrera, Inés M. Figueroa Poleo

The present work has been conducted in order to develop a novel solution for the heat transfer problem during the continuous casting of steel billets and blooms, by using the element-free Galerkin method under a pseudo-transient moving cross-section slice approach. The transport laws, non-linear…

LIDAR and Stereo-Camera fusion for reliable Road Extraction

Mohammed Yazid Lachachi, Mohamed Ouslim, Abdelmalik Taleb-Ahmed, Smail Niar

his paper presents a novel approach that combines LIDAR and Stereo-cameras. First, a stereo camera is used to guide the extraction of road surface points from a 3D point cloud obtained by a LIDAR. Then, the number of points is reduced based on their elevation and illumination invariant colors.…

CFD characterization of a wet foam flow rheological behavior

Heni Dallagi, Ramla Gheith, Ahmad Al Saabi, Christine Faille, Wolfgang Augustin, Thierry Benezech, Fethi Aloui

In some industrial processes, aqueous foams flow presents an important phase of the process, whereas, they cause pressure drop when designing and dimensioning systems. Identifying the different rheological parameters of foam flow is an interest key to understanding the interfacial phenomena.…

Adaptive layout for operating theatre in hospitals: different mathematical models for optimal layouts

Abdelahad Chraibi, Said Kharraja, Ibrahim H. Osman

The adaptive layout for operating theatre (ALOT) problem in hospitals seeks to determine the ‘most efficient’ layout placement of a set of health-care operating facilities, corridors and elevators in a designated area subject to a set of constraints on professional standards. Such standards include…

DeepHPS: End-to-end Estimation of 3D Hand Pose and Shape by Learning from Synthetic Depth

Muhammad Jameel Nawaz Malik, Ahmed Elhayek, Fabrizio Nunnari, Kiran Varanasi, Kiarash Tamaddon, Alexis Heloir, Didier Stricker

Articulated hand pose and shape estimation is an important problem for vision-based applications such as augmented reality and animation. In contrast to the existing methods which optimize only for joint positions, we propose a fully supervised deep network which learns to jointly estimate a full…

Large-scale fractional-order systems: stability analysis and their decentralized functional observers design

Yassine Boukal, Mohamed Darouach, Michel Zasadzinski, Nour-Eddine Radhy

This study concerns the stability analysis of linear large-scale fractional-order systems and its functional observers design. First, based on the diffusive representation of the fractional-order derivative and the indirect Lyapunov approach, the stability of large-scale fractional-order…

Current Signal Analysis of an Induction Machine with a Defective Rolling Bearing

Aroua Fourati, Adeline Bourdon, Didier Remond, Nabih Feki, Fakher Chaari, Mohamed Haddar

With the ultimate goal of rotating machinery diagnosis using Motor Current Signal Analysis (MCSA), this paper provides a coupled electro-magnetic-mechanical model of a rotating shaft supported by rolling bearings and driven by a three-phase squirreled cage motor. The modeling is based on the…
