A method based on the polar decomposition theory is proposed for the calculation of rotation matrix from noisy data in the experimental study of human joint kinematics. The results of instantaneous center of rotation and average center of rotation obtained with the present method coincide with those obtained by using the least square method of spoo...
This three-part article describes the features and applications of the Vehicle for Experimental Research on Trajectories (VERT) as designed and used by the Geopositioning Laboratory at the French Institute of Science and Technology for Transport, Development, and Networks. The first section describes the vehicle's architecture. The second presents ...
RAPPORT D'ETAPE
Le cadre de ce stage est de mieux comprendre le comportement aux interfaces sol/inclusion lors de clouage du sol par la mise en oeuvre de modèles réduits. (DEA de Génie Civil option Ouvrages et structures).
RAPPORT DE CONTRAT
This paper discusses a new approach to vehicle trajectories modeling starting from the experimental trajectories. Firstly, we use an experimental design in order to obtain discrete observations of representative trajectories. Then, we will use clustering method in order to distribute observed trajectories in several class of trajectories. Each iden...
Parmi les méthodes de localisation, les utilisations du système GPS n'ont pas cessé de se multiplier, notamment dans le domaine des transports avec des applications telles que la navigation, la gestion de flotte, la gestion du trafic, etc. La constellation GPS offre une couverture mondiale. Cependant, dans le cadre d'applications transport, la disp...
The analysis of the variability of vehicle trajectories can reveal important information about how situational constraints influence drivers' behaviour (e.g., lateral position and/or speed). Variability in the lateral position using a driving simulator was examined. Forty-two participants had to drive on two road environments: a 3 km straight road ...
Des actions sont menées depuis plusieurs années pour réduire la gêne sonore subie par les riverains des aéroports: réduction du bruit des avions, mesures d'exploitation, maîtrise de l'urbanisation. L'étape suivante consiste à décrire des trajectoires de moindre gêne qu il faut déterminer grâce à un modèle d'optimisation. L'analyse des contraintes s...
The aim of presented work consists in developing an active steering assistance system to avoid the lane departure of heavy vehicle. The controller is based on super twisting algorithm.An estimator based on the sliding mode observer is also developed to estimate the vehicle dynamics. The lateral positions and speeds are then controlled in order to k...
