Measurements of liquid film thickness of a wide horizontal co-current stratified air-water flow

François Touron, Larbi Labraga, Laurent Keirsbulck, Hervé Bratec

A horizontal co-current stratified two-phase flow was studied in a duct with a rectangular section. Its dimensions were such that the top and side walls did not influence the interfacial waves. The film thickness was almost of the millimeter. The Reynolds number based on the mean height and...

Identification of faces by multimodal information fusion of depth and color

Abdelmalik Ouamane, Mebarka Belahcene, Abdelhamid Benakcha, Mohamed Boumehrez, Abdelmalik Taleb-Ahmed

Recognition of traditional optical faces of color images or intensity presents many challenges, such as variations in lighting, pose and expression. In fact, the human face not only generates 2D texture information, but also 3D shape information. In this paper, we examine what information the...

Flow and Heat Transfer of Single-and Two-Phase Boiling of Nanofluids in Microchannels

Gail Duursma, Khellil Sefiane, Alexandre Dehaene, Souad Harmand, Yuan Wang

Experiments using nanofluids in horizontal, rectangular, high-aspect-ratio microchannels were performed where heat was provided electrically to the microchannel wall to bring about heating and phase change while recording temperature (via infrared camera) and channel pressure drop. High-speed video...

Self‐triggered control for multi‐agent systems with unknown non‐linear inherent dynamics

Michael Defoort, Stefano Di Gennaro, Mohamed Djemai

This study focuses on the design of self-triggered controls for first-order multi-agent systems with unknown inherent non-linear dynamics. First, conditions that guarantee the existence of a self-triggered control are provided to solve the consensus problem under fixed communication topologies if...

A two phase variable neighborhood search for the multi-product inventory routing problem

Anis Mjirda, Bassem Jarboui, Rita Macedo, Said Hanafi, Nenad Mladenovic

We address a multi-product inventory routing problem and propose a two-phase Variable Neighborhood Search (VNS) metaheuristic to solve it. In the first phase, VNS is used to solve a capacitated vehicle routing problem at each period to find an initial solution without taking into account the...

Collaborative Sensing for Urban Transportation

Sergio Ilarri, Ouri Wolfson, Thierry Delot

In this paper, we overview the current status of research in the field of collaborative sensing for urban transportation. We first classify the different types of sensors that can be relevant in collaborative urban sensing and then we analyze three different topics: parking spaces, traffic, and...

Approche de détection et d'explication d'erreur de commande par filtrage robuste

Pascale Marangé, Serge Debernard, François Gellot, Marie-Pierre Pacaux-Lemoine, Alexandre Philippot, Thierry Poulain, Bernard Riera, Jean-François Pétin

Ce papier présente les travaux réalisés dans le cadre d'une collaboration entre trois laboratoires – le CRAN, le CReSTIC et le LAMIH -autour de la détection d'erreur de commande. L'objectif de cet article est de proposer une approche de filtrage permettant de se prémunir de toute..., This paper presents the work done between three laboratories: CRAN, CReSTIC and LAMIH, about the control error detection. The objective is firstly to propose a filtering approach to protect the system from any control error and secondly, to propose, if necessary, assistance to understand the error...

Stability analysis of a class of switched linear systems on non-uniform time domains

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai

This paper deals with the stability analysis of a class of switched linear systems on non-uniform time domains. The considered class consists of a set of linear continuous-time and linear discrete-time subsystems. First, some conditions are derived to guarantee the exponential stability of this...

Inter and intra-individual differences in steering wheel hand positions during a simulated driving task

Jessica Schiro, Pierre Loslever, François Gabrielli, Philippe Pudlo

This paper describes an experimental study focusing onto the way drivers use the steering wheel while performing a 2D tracking task. The stimulus during this task was a steering wheel angle signal recorded in real situations involving turns and straight lines performed at about 30 km/h. The hand...

A nonmonotonically decreasing relaxation approach of Lyapunov functions to guaranteed cost control for discrete fuzzy systems

Kohei Inoue, Ying-Jen Chen, Thierry-Marie Guerra, Hiroshi Ohtake, Hua O. Wang, Motoyasu Tanaka, Alexandre Kruszewski, Kazuo Tanaka

This study presents a nonmonotonically decreasing relaxation approach of Lyapunov functions to guaranteed cost control for discrete Takagi–Sugeno (T–S) fuzzy systems. First, the authors summarise the previous results on a relaxation of nonmonotonically decreasing of Lyapunov functions, and newly...
