Biocompatibility of the Electrical Discharge Machining Process on Titanium Surfaces

Maxence Bigerelle, Karine Anselme, Sylvain Giljean

Pure titanium samples were obtained using electrical discharge machining (EDM) on a spark erosion machine. Twenty-two titanium samples were obtained exhibiting a wide range of arithmetic roughness (Ra) varying from 1 to more than 20.9 µm. The surfaces present an isotropic structure formed by...

The undirected m-Capacitated Peripatetic Salesman Problem

Éric Duchenne, Gilbert Laporte, Frédéric Semet

In the m-Capacitated Peripatetic Salesman Problem (m-CPSP) the aim is to determine m Hamiltonian cycles of minimal total cost on a graph, such that all the edges are traversed less than the value of their capacity. This article introduces three formulations for the m-CPSP. Two branch-and-cut...

GeoVanet: A Routing Protocol for Query Processing in Vehicular Networks.

Thierry Delot, Nathalie Mitton, Sergio Ilarri, Thomas Hien

In a vehicular ad hoc network (VANET), cars can exchange infor- mation by using short-range wireless communications. Along with the opportunities oered by vehicular networks, a number of challenges also arise. In particular, most works so far have focused on a push model, where potentially useful...

The impact of perceptual treatments on driver's behavior: >From driving simulator studies to field tests—First results.

Jean-Michel Auberlet, F. Rosey, Françoise Anceaux, Sébastien Aubin, P. Briand, Marie-Pierre Pacaux-Lemoine, Patrick Plainchault

Our study focused on the lateral position of drivers in relation to risk on rural crest vertical curves, using a field site proposed by a local operator of the French road network (Conseil Général de Maine-et-Loire, 49). The final goal was to test one road treatment on this field site. The study...

Distributed Interactive Surfaces: A step towards the distribution of tangible and virtual objects

Sophie Lepreux, Sébastien Kubicki, Christophe Kolski, Jean Caelen

After having outlined the uses of new technologies such as smartphones, touchscreen tablets and laptops, in this paper we present the TangiSense interactive table, equipped with RFID technology tagged on tangible objects, as new paradigm of interaction for ambient intelligence. We propose a problem...

Optimisation de ressources en logistique urbaine, Optimization of multi-modal transportation chains in city logistics

Alexandre Huart

La croissance de la congestion des infrastructures routières, en particulier dans les zones urbaines, est préoccupante et impose de trouver des solutions à la productivité générale de la filière logistique. Nos travaux se reposent sur une solution de mutualisation de capacités logistiques..., The growing congestion of road infrastructure, particularly in urban areas, is alarming and requires solutions to increase the logistics productivity. To achieve this goal, we propose an innovative strategy among all actors of the logistic chain which relies on the mutualization of unused logistic...

Contribution à la prise en considération du contexte dans la conception de tables interactives sous l'angle de l'IHM, application à des contextes impliquant table interactive RFID et objets tangibles

Sébastien Kubicki

Cette thèse s'inscrit dans le domaine de l'Interaction Homme-Machine. Elle vise à prendre en considération le contexte d'usage pour les nouvelles plateformes de type table interactive. Par la notion de table interactive, on laisse supposer un espace de travail collaboratif et co-..., This thesis contributes to the Human-Computer Interaction domain. It aims to take into account the context of use for the new platforms like the interactive tables. By the concept of interactive table, one can suppose a collaborative and co-localized workspace allowing several users to work at the...

Taking context into account in conceptual models using a Model Driven Engineering approach

Arnaud Brossard, Mourad Abed, Christophe Kolski

Context : In public transport, travelers (considered as information systems users) do not have the same objectives and/or concerns at the same time. For this reason it is not always easy to provide them with the right information at the right time. If personalizing the information to the user...
