Adding user experience into the interactive service design loop : a persona-based approach

Djilali Idoughi, Ahmed Seffah, Christophe Kolski

Approaches to service design share human–computer interaction's (HCI's) commitment to developing with and for people useful, usable and accessible services. However, there has been little explicit interaction between the emerging service sciences and the interaction design communities.…

Experimental study of flow behaviour and thermal loads in dual bell nozzles, Étude expérimentale de l'écoulement et des charges thermiques dans une tuyère dual bell

Chloé Génin

The nozzle are currently presenting the most promising optimisation possibilities to supply the increasing needs of the aerospace industry. The dual bell nozzles allow the altitude adaptation of the flow. The inflection forces the flow to a stable and symmetrical separation, gencrating an optimised…, Les tuyères sont actuellement le sous-système présentant les possibilités d'optimisation les plus prometteuses pour répondre aux besoins toujours croissants de l'industrie aérospatiale. Les tuyères dual bell permettent une adaptation à l'altitude. L'écoulement est forcé à…

Hybrid approaches for the two-scenario max-min knapsack problem

Saïd Hanafi, Raïd Mansi, Christophe Wilbaut, Arnaud Fréville

In this paper, we deal with the two-scenario max-min knapsack (MNK) problem. First, we consider several formulations of MNK as a mixed integer programming problem. Then, we propose a hybrid method as an alternative to solve the MNK exactly. The approach combines relaxation technique and the…

Contribution à la formalisation et à l'identification de la stabilité humaine au regard de la sécurité : application aux transports guidés, Contribution to the characterization and identification of human stability in terms of security : application to guided transport

Philippe Richard

Le travail de la thèse propose une contribution originale basée sur le concept de stabilité humaine par l’identification des risques associés dans le cadre de l’évaluation de la sécurité du système. Dans une première partie, les difficultés à prendre en compte les facteurs humains dans les études…, The work of the thesis presents an original contribution based on the concept of human stability by identifying the associated risks as part of the safety system assessment. In a first part, the difficulties to take into account human factors in safety studies are highlighted and definitions of new…

Intelligent Transportation Systems

Mikael Desertot, Sylvain Lecomte, Christophe Gransart, Thierry Delot

Nowadays, vehicles, more specifically cars, are among the most sophisticated tools that are available to us. In fact, car today is a mix of computing involving multiple processors (vehicles are using processors that are more and more powerful and capable of more complex calculations), mechanics (…

Traffic Behavioral simulation in urban and suburban : Representation of the drivers' environment

Feirouz Ksontini, Stéphane Espie, Zahia Guessoum, René Mandiau

The aim of this paper is to improve the validity of traffic simulations in urban and suburban fields, with a better consideration of the driving context and driver behavior in terms of anticipation of positioning on the lanes and occupation of space. Our model is based on a multi-agent approach and…

Quasi-static and dynamic behaviour of the bone structures with fine geometric and materials modelling aspects

Olivier Mayeur, Grégory Haugou, Fahmi Chaari, Rémi Delille, Pascal Drazetic, Eric Markiewicz

The principle aim of this study is to highlight the influence of velocity on mechanical responses of cortical bones. Quasi-static tests are performed on cubic samples from bovine femurs in order to highlight the anisotropic effect of cortical structure. Thanks to the Hopkinson bars technique, a set…

A cooperative scheme to aggregate spatio-temporal events in VANETs

Dorsaf Zekri, Bruno Defude, Thierry Delot

Today, thanks to vehicular networks, drivers may receive useful information produced or relayed by neighboring sensors or vehicles (e.g., the location of an available parking space, of a traffic congestion, etc.). In this paper, we address the problem of providing assistance to the driver when no…

Decision support systems for air traffic controllers based on the analysis of their decision-making processes

David Annebicque, Igor Crevits, Thierry Poulain, Serge Debernard, Patrick Millot

The growth of air traffic generates a multitude of data and parameters that makes it increasing difficult for air traffic controllers to choose rapidly and safely what to decide. The study of air-traffic control of full or partial automation over the past years highlights the need for better tools…

Dynamic slack reclamation strategy for multiprocessor systems

Imen Mhedhbi, Rabie Ben Atitallah, Abderrazak Jemai

Emerging trends in applications with the requirement of considerable computational performance and decreasing time-to-market have urged the need of multiprocessor systems. With the increase in number of processor there is an increased demand to efficiently control the energy and power budget of…
