Context aware business adaptation toward user interface adaptation

Mohamad-Anas Hariri, Dimitri Tabary, Sophie Lepreux, Christophe Kolski

The growth of user mobility has created new user needs. Cellular phones, personal assistants and modern communication means are now required for all user tasks. Users want services that are specifically mobile, but they also want to work with and have access to the same applications on their mobile…

The role of intervening variables in driver-ACC cooperation, Rôle des variables intermédiaires dans la coopération conducteur-ACC

Bako Rajaonah, N. Tricot, Françoise Anceaux, Patrick Millot

This paper analyzes the behavior of drivers using Adaptive Cruise Control (ACC) within the theoretical framework of Human-Machine Cooperation. The study was carried out on a driving simulator. Driving task performance data and responses to a trust questionnaire were analyzed in order to examine the…

Finite-time stability and stabilization of time-delay systems

Emmanuel Moulay, Michel Dambrine, Nima Yeganefar, Wilfrid Perruquetti

Finite-time stability and stabilization of retarded-type functional differential equations are developed. First, a theoretical result on finite-time stability inspired by the theory of differential equations, using Lyapunov functionals, is given. As it may appear not easily usable in practice, we…

A continuous media approach to modeling the stress saturation effect in granular silos

Jamila Rahmoun, Olivier Millet, Géry de Saxcé

A continuous media approach for the calculation of the stresses in an ensiled granular media which improves on the Janssen theory has been developed. This approach also allows us to represent qualitatively as well as quantitatively the stress saturation phenomenon in granular silos. It is based on…

Informal Notes to support the Asynchronous Collaborative Activities

Nathalie Bricon-Souf, Sandra Bringay, Saliha Hamek, Françoise Anceaux, Catherine Barry, Jean Charlet

BACKGROUND: Health care professionals' collaboration is highly important for the medical practice. Efficient exchange of information improves good cooperation, but remains complex, due to the diversity of the medical activities. Currently, the health record is mainly used to manage structured…

Evaluation of agent-based interactive systems : proposal of an electronic informer using Petri Nets

Chi Dung Tran, Houcine Ezzedine, Christophe Kolski

The evaluation of interactive systems has been an active subject of research for many years. Many methods and tools have been proposed but most of them do not take architectural specificities of agent-based interactive systems into account. In addition, electronic informers are popular evaluation…

Relation usinabilité-topographie de la surface usinée. Analyse conventionnelle et par la théorie du chaos

Maxence Bigerelle, Jérome Gavois, Alain Iost

Cet article propose d'analyser l'usinabilité en tournage d'un acier martensitique en fonction de la vitesse de coupe par observation topographique de la surface. Nous décrivons d'abord une méthodologie pour chercher le paramètre de rugosité le plus pertinent afin de caractériser…

Integration of traffic management and traveller information systems : basic principles and case study in intermodal transport system management

Houcine Ezzedine, Thérèse Bonte, Christophe Kolski, Christian Tahon

As they involve many interacting agents behaving in numerous ways that are extremely difficult to predict, urban transportation systems are complex in nature. The development of intermodal passenger transportation solutions to address the mobility issues constitutes a major thrust area of urban…

A dynamic programming based reduction procedure for the multidimensional 0-1 knapsack problem

Stefan Balev, Nicola Yanev, Arnaud Fréville, Rumen Andonov

This paper presents a preprocessing procedure for the 0–1 multidimensional knapsack problem. First, a non-increasing sequence of upper bounds is generated by solving LP-relaxations. Then, a non-decreasing sequence of lower bounds is built using dynamic programming. The comparison of the two…

Sliding-Mode Formation Control for Cooperative Autonomous Mobile Robots

Michael Defoort, Thierry Floquet, Annemarie Kökösy, Wilfrid Perruquetti

This paper considers the control of a group of autonomous mobile robots. A coordinated control scheme based on a leader-follower approach is developed to achieve formation maneuvers. First and second order sliding mode controllers are proposed for asymptotically stabilizing the vehicles to a time-…
