Enabling Mobile Collaborative Learning through Multichannel Interactions

The work presented here shows an architecture to integrate multiple communication channels for a simple communication tool: a weblog. The motivation for this work is to enable learners to access learning services regardless of their situation. Indeed, in some cases the access to these services is quite hard because people are on the move or don't easily have access to an Internet connection. This article presents the different elements that fit into the architecture which lay the path for a richer mutichannel learning environment based on Service Oriented Architecture

Supporting Mobile Connectivity: from Learning Scenarios to Multichannel Devices: Special Issue on "Learning as a Ubiquitous and Continuous Communication Attitude"

Guest Editor: Piet KommersInternational audienceThe introduction of distance learning does not only bring a wider audience, but also much more diversity among the learners: first, because it can be integrated more easily into a Life-long Learning strategy; secondly, because the learners are not restricted to a sing le area and thus learners from different countries and with different cultures follow the curriculum. We have observed this in various DL diplomas in which we participate. In this article, we will shed some light on the difficulties and challenges arising from these multi-cultural settings. Based on our research work, we would like to insist on two particular points which are the necessity to adapt the pedagogical settings (e.g. pedagogical scenarios) according to the learners' behaviour to overcome unforeseen problems due to cultural differences and the importance of considering mobile technologies to overcome limited access to the technology in developing countries and to ensure continuous interaction among learners and with tutors

Digital Investigation of IoT Devices in the Criminal Scene

The Internet of Things (IoT) is everywhere around us. Smart communicating objects are offering the digitalization of lives. They create new opportunities within criminal investigations. In recent years, the scientific community sought to develop a common digital framework and methodology adapted to IoT-based infrastructure. However, the difficulty in exploiting the IoT lies in the heterogeneous nature of the devices, the lack of standards and the complex architecture. Although digital forensics are considered and adopted in IoT investigations, this work only focuses on the collection. The identification phase is quite unexplored. It addresses the challenges of locating hidden devices and finding the best evidence to be collected. The matter of facts is the traditional method of digital forensics does not fully fit the IoT environment. Furthermore, the investigator can no longer consider a connected object as a single device, but as an interconnected whole one, anchored in a cross-disciplinary environment. This paper presents the methodology for identifying and classifying connected objects in search of the best evidence to be collected. It offers techniques for detecting and locating the appropriate equipment. Based on frequency mapping and interactions, it transfers the concept of "fingerprinting" into the field of crime scene. It focuses on the technical and data criteria to successfully select the relevant IoT devices. It gives a general classiffication as well as the limits of such an approach. It shows the collection of digital evidence by focusing on pertinent information from the Internet of Things

Everlasting sensor networks

Poster for " L'énergie demain. Transition énergétique : recherches et ingénierie " symposium. May 30-31, 2013, MINES ParisTechWithin the team CSAM (Circuits, Systèmes et Applications des Microondes) of IEMN (Institut d'Électronique, de Microélectronique et de Nanotechnologie) and within IRCICA (Institut de Recherche sur les Composants logiciels et matériels pour l'Information et la Communication Avancée - USR CNRS 3080) we develop a research on ultra low power sensor networks. Our goal is to minimize the energy consumption so that the life duration of the network could be infinitely long. We develop studies including nanotechnologies (energy harvesting, storage devices), RF front-ends design, energy management but also radio channel and interference modeling and MAC layer optimization

Workflow and Mobile Devices in Open Distance Learning

pp. 123-126International audienceNowadays, thanks to new tools and devices, students have more possibility to learn in a mobile way. Hence, e-learning platforms should support user mobility by offering access points to mobile devices. The system must adapt information corresponding to a learning activity to device's capabilities. Documents are provided in accordance to activities performed. For the coordination of activities we designed a flexible work-flow system named Cooperative Open Workflow. In this paper, we present our architecture which aims to support work coordination and user mobility

Les objets connectés dans les missions judiciaires

International audienceLa généralisation des technologies de l'information interactives dans le quotidien constitue, avec la prolifération des objets intelligents communicants, un enjeu d'actualité dans le cadre des missions judiciaires. Peu visibles, à l'exception des plus populaires d'entre eux comme, entre autres, les montres connectées, ces derniers s'invitent et participent à notre quotidien. Tous les secteurs d'activité sont touchés par cette numérisation accélérée. L'Internet des objets, IdO (en anglais, IoT), suscite aujourd'hui autant de promesses d'opportunités économiques, sociétales et judiciaires que de questions, voire d'inquiétudes, certaines de portée stratégique. Dans cet article, nous exposons les opportunités offertes par les objets connectés dans le cadre des missions judiciaires. Nous nous intéressons également à quelques-unes des nouvelles menaces liées à l'usage et au déploiement de ces écosystèmes

COW, un service de support d’exécution de scénarios pédagogiques

This article deals with supporting the execution of pedagogical scenarios in Learning Management Systems by the means of a workflow service. It takes an engineering point of view to identify actors, design and use processes. Based on this point of view, we define the characteristics of a service to support the actors and the pedagogical scenarios. Then, we present the design and the implementation of Cooperative Open Workflows (COW), the flexible workflow based execution service we have developed.Cet article présente un service de support d’exécution de scénarios pédagogiques conçu pour être intégré dans des plates-formes de formation existantes. Dans un premier temps nous prenons un point de vue ingénierie des plates-formes afin d’identifier les processus de conception et d’utilisation ainsi que les acteurs qui y sont associés. Dans un deuxième temps nous présentons les caractéristiques nécessaires que doit offrir notre service afin que les différents acteurs puissent gérer et utiliser des scénarios pédagogiques. La suite de l’article est consacrée à la présentation de la conception et de l’utilisation du service que nous avons développé. Nous présenterons plus en détail l’implémentation et la gestion des modèles de notre service qui est basé sur un système de workflows flexible.Vantroys Thomas, Peter Yvan.
