Obtaining empirical data from experimentations on railway operational simulator for human reliability modelling

Subeer Rangra, Mohamed Sallak, Walter Schön, Frédéric Vanderhaegen

Quantitative Human Reliability Analysis (HRA) models aims to predict Human Error Probabilities (HEPs) for a given set of conditions. Owing to lack of empirical data most HRA methods use expert data. This paper presents a protocol to obtain empirical data from simulator experimentations. It aims to…

Real-Time Multi-Scale Pedestrian Detection for Driver Assistance Systems

Maryam Hemmati, Morteza Biglari-Abhari, Smail Niar, Stevan Berber

Pedestrian detection is one of the most challenging and vital tasks of driver assistance systems (DAS). Among several algorithms developed for human detection, histogram of oriented gradients (HOG) followed by support vector machine (SVM) has shown the most promising results. This paper presents a…

Marangoni Flow Induced Evaporation Enhancement on Binary Sessile Drops

Pin Chen, Souad Harmand, Safouene Ouenzerfi, Jesse Schiffler

The evaporation processes of pure water, pure 1-butanol, and 5% 1-butanol aqueous solution drops on heated hydrophobic substrates are investigated to determine the effect of temperature on the drop evaporation behavior. The evolution of the parameters (contact angle, diameter, and volume) during…

Predicting fluorescence quantum yield for anisole at elevated temperatures and pressures

Qianlong Wang, Khanh-Hung Tran, Céline Morin, Jérôme Bonnety, Guillaume Legros, Philippe Guibert

Aromatic molecules are promising candidates for using as a fluorescent tracer for gas-phase scalar parameter diagnostics in a drastic environment like engines. Along with anisole turning out an excellent temperature tracer by Planar Laser-Induced Fluorescence (PLIF) diagnostics in Rapid Compression…

Adaptive video-based algorithm for accident detection on highways

Boutheina Maaloul, Abdelmalik Taleb-Ahmed, Smail Niar, Naim Harb, Carlos Valderrama

For the past few decades, automatic accident detection, especially using video analysis, has become a very important subject. It is important not only for traffic management but also, for Intelligent Transportation Systems (ITS) through its contribution to avoid the escalation of accidents…

Une simple heuristique pour rapprocher DFS et LNS pour les COP

Julien Vion, Sylvain Piechowiak

Dans cet article, nous montrons comment une combinaison de stratégies de branchement et de redémarrages pour la recherche en profondeur d’abord (DFS) permet de reproduire le fonctionnement de la recherche par grand voisinage (LNS) pour la résolution de problèmes d’optimisation à contraintes, ce qui…, In this paper, we argue that a combination of wellknown and new search strategies enables Depth First tree Search (DFS) to mimic the behavior of Large Neighborhood Search (LNS), which reduces considerably the gap between the two techniques. In particular, we are able to implement a DFS strategy…

Direct Compression Loading Using the Pre-stretched Bar Technique: Application to High Strains Under Moderate Strain Rates

Grégory Haugou, Hervé Morvan, Nicolas Leconte

The mechanical properties of ductile materials are of high interest in the domain of energy absorption, high speed forming processes, machining processes and ballistics. The range of the intermediate strain rates has always been required for the main testing devices, particularly for classical…

Multi-Physic Analysis of Electrical Machines: Hybrid Electro-Magneto-Aero-Thermal Modeling

Oualid Messal, Louis Lambourg, Frédéric Dubas, Souad Harmand, Afef Lebouc, Christian Chillet

In this paper, a multi-physic approach allowing the accurate analysis of electrical machines is presented. This original approach exploits a generalized nonlinear adaptive magnetic equivalent circuit (MEC), a dynamic hysteresis model and an aerothermal model. The model coupling has been applied to…

An Energy-Aware Learning Agent for Power Management in Mobile Devices

Ismat Chaib Draa, Emmanuelle Grislin-Le Strugeon, Smail Niar

The optimization of the energy consumption in mobile devices can be performed on hardware and software components. For example, reducing the screen brightness or switching off GPS. The energy control must take into account both the current context and user habits, on the base of usage knowledge…

Replication in Fault-Tolerant Distributed CSP

Fadoua Chakchouk, Julien Vion, Sylvain Piechowiak, René Mandiau, Makram Soui, Khaled Ghedira

Real life problems can be solved by a distributed way, in particular by multi-agent approaches. However, the fault tolerance is not guarantee when an agent, for example, does not have any activity (e.g. it dies). This problem is very crucial, when the interactional model is based on a Distributed…
