Coadaptive brain-machine interface via reinforcement learning

This paper introduces and demonstrates a novel brain-machine interface (BMI) architecture based on the concepts of reinforcement learning (RL), coadaptation, and shaping. RL allows the BMI control algorithm to learn to complete tasks from interactions with ...

Paper-based Concept Map: the Effects of Tabletop on an Expressive Collaborative Learning Task

Pierre Dillenbourg, Frédéric Kaplan

Augmented tabletops have recently attracted considerable attention in the literature. However, little has been known about the effects that these interfaces have on learning tasks. In this paper, we report on the results of an empirical study that explores ...

A Simulation-Based Expert System for Daylighting Design

Marilyne Andersen

In this paper, we propose an expert system for daylighting in architecture which is used to guide a goal-oriented, user-interactive design process. This system is supported by a knowledge-base which has been populated using a set of previously completed si ...

Phase-field simulations of alpha -> gamma precipitations and transition to massive transformation in the Ti-Al alloy

Alain Jacot

A phase-field model for the solid-solid alpha -> gamma transition of Ti-Al binary alloys is presented based on analytical Gibbs free energies and couplings to the thermodynamical database ThermoCalc. The equilibrium values recover the alpha + gamma phase b ...

Velocity profiles and interface instability in a two-phase fluid: investigations using ultrasonic velocity profiler

Anton Schleiss, Giovanni De Cesare, Azin Amini

In the present study the velocity profiles and the instability at the interface of a two phase water-oil fluid were investigated. The main aim of the research project was to investigate the instability mechanisms that can cause the failure of an oil spill ...

Supporting Dimensional Analysis in SystemC-AMS

Alain Vachoux

This paper will introduce new modeling capabilities for SystemC-AMS to describe energy conserving multi-domain systems in a formal and consistent way at a high level of abstraction. To this end, all variables and parameters of the system model need to be a ...

Finite element model of primary recrystallization in polycrystalline aggregates using a level set framework

Roland Logé

The paper describes a robust finite element model of interface motion in media with multiple domains and junctions, as is the case in polycrystalline materials. The adopted level set framework describes each domain (grain) with a single level set function, ...

Watch-dictaphone for Automatic Medical Codification

Pierre-André Farine, Sara Grassi Pauletti, Patrick Stadelmann, Frédéric David Meylan

This paper describes the development of a voice data recording watch and the accompanying software and hardware needed to build an integrated solution for medical data capture and automatic codification. The developed system is used to capture on the stand ...

Tinkering or Sketching: Apprentices’ Use of Tangibles and Drawings to Solve Design Problems

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey

The articulation of practice and theory is a central problematic in a dual apprenticeship system that combines working in a company and attending courses at school. Design problems are proposed by teachers as a way to address theoretical concepts in a prac ...

A Tabletop Learning Environment for Logistics Assistants: Activating Teachers

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey

We describe a tabletop environment used in vocational schools to teach theoretical concepts to apprentices in lo gistics through the use of a small-scale model of a ware house. It provides a Tangible User Interface in the form of wooden shelves, metallic p ...
