Détecter la somnolence des conducteurs dans le transport terrestre, Detecting driver drowsiness in land transport. state of the art

Nedjemi Rachedi, Denis Berdjag, Frédéric Vanderhaegen

In this paper we present a survey of driver states monitoring methods with a special interest in drowsiness and fatigue states detection. We provide a comprehensive view of the field, previous work and encountered problems, proposed solutions and we give some insights on new research directions.…

Optimization of the Straightness Measurements on Rough Surfaces by Monte Carlo Simulation

François Hennebelle, Thierry Coorevits, Maxence Bigerelle

The straightness error of a coordinate measuring machine (CMM) is determined by measuring a rule standard. Thanks to a reversal technique, the straightness uncertainty of the CMM is theoretically dissociated from the straightness uncertainty of the rule. However, stochastic variations of the whole…

Performance of system based on two ontologies in order to supply personalised information

Houda Mnasser, Faiez Gargouri, Mourad Abed

This paper describes two ontologies that form the backbone of our personalised interactive system allowing the passengers to assist, to facilitate their movement and offer them services, entertainment, etc., throughout their journey in the multimodal transport networks. First, we describe here the…

Reflection on the Measurement and Use of the Topography of the Indentation Imprint

Julie Marteau, Maxence Bigerelle, Salima Bouvier, Alain Iost

The goal of this paper is to study the main uses of the residual imprint of the indentation test. It also discusses the different technologies and methods employed in this context. The difficulties encountered when trying to exploit the full potentials of the imprint are thoroughly examined. A…

Folk-IS : Opportunistic Data Services in Least Developed Countries

Nicolas Anciaux, Luc Bouganim, Thierry Delot, Sergio Ilarri, Leila Kloul, Nathalie Mitton, Philippe Pucheral

According to a wide range of studies, IT should become a key facilitator in establishing primary education, reducing mortality and supporting commercial initiatives in Least Developed Countries (LDCs). The main barrier to the development of IT services in these regions is not only the lack of…

Building, sharing and exploiting spatio- temporal aggregates in vehicular networks

Dorsaf Zekri, Bruno Defude, Thierry Delot

This article focuses on data aggregation in vehicular ad hoc networks (VANETs). In such networks, data produced by sensors or crowdsourcers are exchanged between vehicles in order to warn or inform drivers when an event occurs (e.g., an accident, a traffic congestion, a parking space released, a…

To pass or not to pass: More a question of body orientation than visual cues

Aurore Bourrelly, J-L Vercher, L. Bringoux

This study investigated the influence of pitch body tilt on judging the possibility of passing under high obstacles in the presence of an illusory horizontal self-motion. Seated subjects tilted at various body orientations were asked to estimate the possibility of passing under a projected bar (i.e…

Optimized Hybrids

Sebastien Delprat, Christian Fontaine, Sebastien Paganelli

Today, hybrids are on the road, from affordable micro hybrids providing mostly the stop&start feature, up to more expensive systems with signifi - cant pure electric mode range. One of the challenges is to improve the control algorithms to reach better fuel economy and reduce emissions.…

Representation of the Agent Environment for Traffic Behavioral Simulation.

Feirouz Ksontini, Stéphane Espié, Zahia Guessoum, René Mandiau

The aim of this paper is to improve the validity of traffic simulations in (sub-)urban context, with a better consideration of driver behavior in terms of anticipation of positioning on the lanes and occupation of space. We introduce a model based on a multi-agent approach and the emergence concept…

Adaptive Super-Twisting Observer for Estimation of Random Road Excitation Profile in Automotive Suspension Systems

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort

The estimation of road excitation profile is important for evaluation of vehicle stability and vehicle suspension performance for autonomous vehicle control systems. In this work, the nonlinear dynamics of the active automotive system that is excited by the unknown road excitation profile are…
