    Méta heuristiques pour le Placement Optimisé des Noeuds Routeur Dans un Réseau de Capteurs Sans Fil

    Les Réseaux de Capteurs Sans Fils (RCSF) sont des réseaux de dispositifs interconnectés qui permettent la récupération de données sur des phénomènes physiques tels que : la température, l’humidité, la présence, … . Dans ce papier nous abordons le problème de déploiement d’un RCSF. Notre étude vise à générer une topologie optimale d’un RCSF sous […]

    Exploration of Students’ Misconceptions in Mechanics using the FCI

    During 3 years, we have used the Force Concept Inventory (FCI) to assess the progress of our First-Year students in Engineering in mastering the concepts of Newtonian Physics and to compare the efficiency of two teaching methods, courses and drills versus Problem-Based Learning. If both methods lead to quite similar deceptive results, the detailed analysis […]

    Design and evaluation of inventive avatars for creativity and innovation

    A challenge today is to create favorable conditions for creativity while enabling geographically distant people to work together. In this context, we study the virtual and digital self representation (i.e., avatar) as a medium for stimulating creativity, in line with the Proteus effect. This paper proposes a methodology for designing, evaluating and identifying relevant avatars […]

    Encouraging innovation activity: in the specific context of smalland medium-sized retailers

    This paper aims at formalizing an innovation process well suited for small- and medium-sized enterprises (SMEs) specialized in retail. The design research consisted in analyzing conceptual models of innovation process from the literature and adapting it to the specific context. Indeed, the research issue deals with encouraging innovation activity in the context of small- and […]

    Why are online games so self-involving: A social identity analysis of massively multiplayer online role-playing games

    This article investigates the ways in which players of massively multiplayer online role-playing games (MMORPGs) internalize being a player into their self-concept. In accordance with the social identity framework, we assume that being a player and being a member of a guild within the game can both shape the social identity of members. In two […]

    L’imagerie cérébrale et la conception de produit : vers de nouveaux outils d’évaluation

    Nous proposons dans cet article un état de l’art de l’utilisation de la neuroimagerie (ou imagerie cérébrale) à des fins non médicales. Depuis quelques années sont apparues de nouvelles disciplines autour de l’imagerie cérébrale : neuroergonomie, neuromarketing, neuroesthétique. Dans la littérature, il existe deux champs de recherche ayant deux finalités différentes : – La substitution […]

    An Efficient Study of Scheduling Algorithms with Freidman Test in WiMAX Networks

    In this paper, we evaluate and compare our scheduling strategy for various IPTV services traffic over 802.16j networks with several scheduling algorithms such as Strict Priority algorithm (SP), Weighted Round Robin (WRR), and Modified Dynamic Weighted Round Robin (MWRR). The proposed scheme adapts dynamically the scheduler operation to according queue load and QoS constraints. In […]

    Modélisation d’un plan de maintenance basé sur les systemes multi-agents pour les éoliennes offshore

    La maintenance des éoliennes offshore est une tâche complexe et coûteuse qui représente un vrai défit pour l’évolution de cette source d’énergie. La taille des parcs d’éoliennes offshore, la taille des éoliennes elles-mêmes, la distance qui les sépare de la côte, et les conditions météorologiques difficiles rendent non évident l’établissement d’une stratégie de maintenance efficace.

    3D and 2D face recognition based on image segmentation

    In this paper we propose a framework for 3D Face Recognition System (3DFRS) using segmentation by grouping of regions of facial images before and after fusion of two modalities (color and depth images). Firstly, the detection of face region is based on the localization of nose tip and integral projection curves. Then, the features resulting […]
