Unified Driver Model simulation and its application to the automotive, rail and maritime domains

Pietro Carlo Cacciabue, Simon Enjalbert, Håkan Söderberg, Andreas Tapani

This paper describes the implementation of a model of a driver into a computerised numerical simulation. The model is developed to capture the essential characteristics and common aspects of cognition and behaviour of a human being in control of a “vehicle” in different surface transport systems,…

A three-dimensional study of electronic component cooling using a flat heat pipe

Hamdy Hassan, Souad Harmand

In this article, a three-dimensional thermal and hydrodynamic numerical model using a flat heat pipe (vapor chamber) is proposed for cooling of electronic components. The heat pipe is composed of a vapor region sandwiched between two wick regions, which are covered by two flat copper plates. A…

Plastic deformation of structural steels under hot-working conditions

Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, Damien Barbier, Mirentxu Dubar, Jacky Lesage

The present study has been conducted in order to formulate a rational description of the flow stress of structural steels, when these are deformed in tension under hot-working conditions. The simplified formulation that has been developed only involves the analysis of the positive work-hardening…

One-level reformulation of the bi-level Knapsack problem using dynamic programming

Luce Brotcorne, Said Hanafi, Raïd Mansi

In this paper, we consider the Bilevel Knapsack Problem (BKP), which is a hierarchical optimization problem in which the feasible set is determined by the set of optimal solutions for a parametric Knapsack Problem. We introduce a new reformulation of the BKP into a one-level integer programming…

Impatience and time pressure: subjective reactions of drivers in situations forcing them to stop their car in the road

Janick Naveteur, Stéphanie Coeugnet, Camilo Charron, Lisa Dorn, Françoise Anceaux

Transportation research has shown that impatience and time pressure are determining factors for traffic rule violation and risky behaviour. However, the situations provoking impatience have not yet been investigated in depth. One purpose of this study was to examine how different road stops might…

Time pressure and driving: Work, emotions and risks

Stéphanie Coeugnet, Janick Naveteur, Pascal Antoine, Françoise Anceaux

Abstract Little is known about how time pressure affects driving behavior. The present questionnaire-based research addresses this gap in the literature. We used roadside assessment, out-of context self-assessment and hetero-assessment approaches. These approaches (1) identify situational factors…

Large-Eddy simulation of turbulent heat transfer in pipe flows with respect to Reynolds and Prandtl number effects.

Meryem Ould-Rouiss, M. Bousbai, A. Mazouz

Heat transfer in a fully developed turbulent pipe flow is investigated by use of the large eddy simulation technique. Isoflux condition is imposed at the wall. Four Prandtl numbers are considered (0.71,3,5,7) and three Reynolds numbers (5500, 10000, 20000). The effects of Reynolds and Prandtl…

Robustness study and reliability growth based on exploratory design of experiments and statistical analysis: a case study using a train door test bench

Laurent Cauffriez, Pierre Loslever, Nathalie Caouder, Fabien Turgis, Reynald Copin

This paper presents a methodology to improve the reliability/robustness of a complex mechatronic system for passenger access, which is greatly stressed over its life cycle. The proposed methodology aims to weed out design problems during the development phase and to test the robustness of the…

User Profile and Multi-criteria Decision Making: Personalization of Traveller's Information in Public Transportation

Soumaya Moussa, Makram Soui, Mourad Abed

Personalization plays an important role in information systems. It is an effective solution for reducing complexity when searching information. In this way, the user feels like the system was developed for him/her. In this context, personalization can be seen as an optimization problem. To this end…

Natural convection heat transfer of nanofluids along a vertical plate embedded in porous medium

Ziya Uddin, Souad Harmand

The unsteady natural convection heat transfer of nanofluid along a vertical plate embedded in porous medium is investigated. The Darcy-Forchheimer model is used to formulate the problem. Thermal conductivity and viscosity models based on a wide range of experimental data of nanofluids and…
