is deploying a flexible learning scheme for selected pilot courses in engineering education. In such a scheme, traditional lectures and written exercises are combined with additional Web-based learning resources. The main objective of this initiative is to sustain the evolution from traditional teaching to active learning and to better integrate the(More)
Benefiting from the advent of social software, information sharing becomes pervasive. Personalized rating systems have emerged to evaluate the quality of user-generated content in open environment and provide recommendation based on users' past experience. In this paper, a trust-based rating prediction approach for recommendation in Web 2.0 collaborative(More)
Web-based experimentation is a key feature in the deployment of eLearning solutions for engineering education. At the Swiss Federal Institute of Technology in Lausanne (EPFL), Web-based experimentation is deployed thanks to a comprehensive environment called the Cockpit. This environment integrates all the components necessary to carry out hands-on practice(More)
—This paper presents investigations on formal and informal requirements for personal learning environments taking into account students' personal and social learning practices. The potential of global Web 2.0 educational service bundles and informal learning communities, as well as their recommendation by educators are addressed. A scenario showing how(More)
A new approach to developing Web-enabled environments for remote diagnostics, maintenance, and experimentation in engineering is based on a middleware layer that uses a Java-lntemet-Labview server to provide communication between Java programs and Labview virtual instruments. The authors illustrate their technique by applying it to the development of a(More)
This paper presents an innovative approach in flexible learning that can facilitate hands-on activities in engineering education. The approach focuses on the mediation role of artifacts within a learning community. The artifacts serve both as a medium and as a product of the collaboration process in the community. We have proposed the eJournal as a(More)
This paper presents a federated search and social recommendation widget. It describes the widget’s interface and the underlying social recommendation engine. A preliminary evaluation of the widget’s usability and usefulness involving 15 subjects is also discussed. The evaluation helped identify usability problems that will be addressed prior to the widget’s(More)
This paper presents a decentralized model predictive control approach for the coordination of autonomous vehicles at intersections. A linear quadratic optimal controller is introduced for each vehicle with predefined path, in order to minimize energy as well as to pass intersection smoothly. We guarantee collision avoidance by adding linear constraints to(More)
