Actuators based on magnetorheological fluids represent an innovative technology to optimize brakes and clutches. Compared to conventional electromechanical systems, MRF actuators show improved and advanced characteristics featuring a smooth adjustable torque, a fast response time, a noiseless operation and a reduced design space. In the present paper, the authors propose an actuator design for a MRF based clutch combined with an integrated electric drive. The actuator design is a further development with enhanced performances considering the torque capacity. Both functionalities of this actuator can be controlled widely independent due to a suitable adjustment of the magnetic field. Therefore a model and a new control strategy are developed. The capability of this concept is proven by measurements of a new proof-of-concept prototype that provides an appropriated ratio between coupling and motor torque of 5:1. This highly integrated mechatronical actuator system allows the design of innovative applications whereby novel features are feasible.

This poster describes a challenging application field for EDM, in the context of collaborative learning open learner model frameworks. An open and challenging field arises from the situation lived by children suffering a serious illness. The responsibility of the government continuing their schooling process is harder to achieve, since different communities (family, school teachers, hospital teachers, medical doctors, psychologists...) have to be coordinated. An appropriate educational solution, designed for this situation should solve the specific issues that arise in the described situation: Motivation, Isolation, Heterogeneity, Spatial Dispersion, Dynamicity, etc. This poster tries to explain the reasons that makes this context specially interesting for EDM;It proposes a framework to support learning in the cited environment based on the use of Multi-user virtual environments (MUVEs);And it points out some Data Mining fields specially appropriate for the problem of analysis of educational data and interactions among students for the construction of an Open Learner Model (OLM), suitable to for decision support.
In this paper we propose a robust sliding mode control strategy for the position control of a hoisting crane. The strategy employs a time-varying switching line which moves with a constant jerk and a constant angle of...

Students learning effectively in groups encourage each other to ask questions, explain and justify their opinions, articulate their reasoning, and elaborate and reflect upon their knowledge, and computer tools can help them producing these kind of collaborative learning situations. In this sense, we have developed several tools to support the collaborative learning-process for the computer Architecture's subject in computers Science engineering. This paper present an intelligent tool called SIENA, composed by the open student model, a student conceptual map with multimedia learning nodes (MLN) and Bayesian tests.
