An Energy-efficient Location Provider for Daily Trips

It is well known that smartphones are energy greedy and their batteries do not last more than a few days. Since mobile phones consumption increased faster than batteries capacities it becomes important to find new ways to reduce their energy consumption. We claim that people using GPS location service everyday should not pay a full energy-cost since most of the time their are taking the same path to commute. Based on these observations, we developed a new implementation of the location API built from Android Location API, which is capable of learning and predict user location on time with an average accuracy of 50 meters while saving energy.Il est généralement admis que les smartphones sont des appareils qui consomment énormément d'énergie et qui nécessitent d'être rechargés régulièrement. Cet état de fait est en partie lié à l'évolution de la consommation de ces derniers qui augmente plus rapidement que celle de la capacité des batteries. Aussi, nous observons qu'une grande partie de la population utilise la localisation par GPS quotidiennement et en parcourant généralement les mêmes routes afin de, par exemple, connaître les conditions de circulation ou du temps restant. Á partir de ces observations, nous proposons une nouvelle mise en {\oe}uvre de l'API de localisation, basée sur celle d'Android, capable d'apprendre et de prédire la position des utilisateurs avec une précision moyenne de cinquante mètres tout en diminuant sa consommation au fil du temps

Knowledge formalization in experience feedback processes : an ontology-based approach

Because of the current trend of integration and interoperability of industrial systems, their size and complexity continue to grow making it more difficult to analyze, to understand and to solve the problems that happen in their organizations. Continuous improvement methodologies are powerful tools in order to understand and to solve problems, to control the effects of changes and finally to capitalize knowledge about changes and improvements. These tools involve suitably represent knowledge relating to the concerned system. Consequently, knowledge management (KM) is an increasingly important source of competitive advantage for organizations. Particularly, the capitalization and sharing of knowledge resulting from experience feedback are elements which play an essential role in the continuous improvement of industrial activities. In this paper, the contribution deals with semantic interoperability and relates to the structuring and the formalization of an experience feedback (EF) process aiming at transforming information or understanding gained by experience into explicit knowledge. The reuse of such knowledge has proved to have significant impact on achieving themissions of companies. However, the means of describing the knowledge objects of an experience generally remain informal. Based on an experience feedback process model and conceptual graphs, this paper takes domain ontology as a framework for the clarification of explicit knowledge and know-how, the aim of which is to get lessons learned descriptions that are significant, correct and applicable

Towards cognitive engineering workbenches considering the time for the intelligent design of operator assistance tools

International audienceIn this article, we will first of all study the problematic issues of knowledges and of temporal strategies used by the human operator in the control rooms of complex industrial process. We will then check off and discuss the different tools and the current knowledge engineering workbenches which are susceptible to make the knowledge acquisition, structuralization and formalization easier for the ergonomist and the knowledge engineer. Finally, we will emphasize on certain temporal tools available in Artificial Intelligence which can contribute to the development of knowledge engineering workbench considering explicitly the time

Le rôle du pharmacien d'officine dans la prise en charge des escarres

Suite au vieillissement de la population, la prévalence de l escarre tend à augmenter. Sa prise en charge est multidisciplinaire, et fait notamment intervenir le pharmacien. En ville, ce dernier est un interlocuteur de proximité qui se met à la portée de tous pour être un lien entre les patients et les autres acteurs de santé. Son rôle est peu évoqué dans la littérature alors qu il peut intervenir à tous les niveaux de la prise en charge de l escarre. Il peut apporter ses connaissances et être un atout dans cette dynamique de soins. Pour optimiser cette mission de santé, le pharmacien d officine peut se munir d outils utiles à la fois pour la délivrance de pansements ou de matériels, mais aussi pour l agencement de l officine et le conseil auprès du patient.LILLE2-BU Santé-Recherche (593502101) / SudocSudocFranceF
