The underlying idea of this work is that the system coherency rules assumptions are guaranteed by the structure of the deployment environment itself and no assumption is made on of the internal behaviours of agents. Thus, every agent has to follow the rules of the deployment environment to being able to interact with others. So, any misuse will be transparently rejected by the structure and other agents are not affected by bogus actions.

De tels services sont des enjeux politiques majeurs, ce sont des outils permettant de replacer les citoyens au centre du debat politique et de court-circuiter une partie de l'inertie liee a la delegation. Un des problemes majeurs de tels outils est le cout de traitement des contenus produits lors de debats a grande echelle. Pour lever ce verrou nous proposons l'utilisation de modalites discursives et experimentons leur praticabilite et utilite percue.

However, the rise of social games in social networks has also played an interesting part in social games awareness. In this paper we focus on ‘social' casual games in Facebook. Our assumption is that the success of games in the Facebook context is linked to the blending of personal and social aspects. In particular: (i) the engagement in ‘fictional' social actions, (ii) the use of asynchronous actions, (iii) the combination of public and private actions within the game. The three above-mentioned aspects contribute to the emergence of particular social groupings, very similar to Cova's tribes. In order to demonstrate the previous assertions the paper will first define a set of basic concepts and will then describe some practical examples from the Facebook context.

Dans cette these nous considerons qu'un cadre de conception et de developpement dans le contexte de l'AEC doit repondre aux points suivants: gestion de l'intermittance des communications, la composition des systemes, le respect de l'autonomie des entites, et l'interoperabilite. Pour repondre aux trois premiers points le modele algebrique d'infrastructure nomme Mouvement, Interaction, Computation (MIC*) est propose. L'autonomie des agents est garantie grâce a l'integrite structurelle. Le modele d'interaction est persistant ce qui permet de s'affranchir des intermittences du medium de communication. La composition des systemes est realisee par la composition des environnements de deploiement. L'interoperabilite est abordee p...

It is an interactive process in which learners cooperate by exchanging arguments and counter-arguments to solve a common question. We propose a debate-based learning game for mathematics classroom to teach how to structure and build mathematical proofs. Dung’s argumentation framework and its extensions are used as a means to extract acceptable arguments that form the proof. Moreover this allows instructors to provide feedbacks to learners without information over-

We can identify at least three levels of inclusion in social rehabilitation: 1. Patient to Patient (Quite-symmetric collaboration or competition) This first level presents challenges related to the patients' physical abilities. In fact, the specific abilities that will be affected by stroke depend on the location, type and size of the lesion. Each patient is then characterized by a specific combination of deficits (National Stroke Association, 2010). Therefore, stroke rehabilitation programs are strongly personalized: they are adapted to a particular patient, to regain as much function as possible. Because each stroke is different from another it is possible to treat patients in independently but it's very difficult to treat them together. For example, two patients who have different recovery degrees would not be able to collaborate on the same exercis...

To do so, the trajectory of our hand is the result of an optimal balance between feed-forward and feed-back control in the face of signal-dependant noise in the sensorimotor system. How far do these principles of trajectory formation still apply after a stroke, for persons with mild to moderate sensorimotor deficits who recovered some reaching ability? Here, we examine the accuracy of fast hand reaching movements with a focus on the information capacity of the sensorimotor system and its relation to trajectory formation in young adults, in persons who had a stroke and in age-matched control participants. We find that persons with stroke follow the same trajectory formation principles, albeit parameterized differently in the face of higher sensorimotor uncertainty. Higher directional errors after a stroke result in less feed-forward control, hence more feed-back loops responsible for segmented movements. As a...

Ubiquitous software systems are considered as a case of study.
