This thesis describes algorithms on planar maps (graphs embedded in the plane without edge-crossings) based on their combinatorial properties. For several important families of planar maps (3-connected, triangulations, quadrangulations), efficient procedures of random generation, encoding, and straight-line drawing are described. In particular, the first optimal encoder for the combinatorial in...

Perception d'états affectifs et apprentissage

This article deals with the problem of affective states recognition from physical and physiological wearable sensors. Given the complex nature of the relationship between available signals and affective states to be detected we propose to use a statistical learning method. We begin with a discussion about the state of the art in the field of statistical learning algorithms and their application...

Adaptabilité et validation de la traduction de B vers C. Points de vue et résultats du projet BOM

This paper presents some results of the RNTL BOM project (B Optimizing Memory). The goal was to design and implement a translator from B to C easily adaptable to memory constraints (embedded software on smart cards). We propose an extension method of the basic data types able to include some types of the target language. We present how the translator is described by the way of translation rules...

Combiner suivi de l'activite? et partage d'expe?riences en apprentissage par projet pour les acteurs tuteurs et apprenants

Our work aims to study tools offered to students and tutors involved in face-to-face or blended projectbased learning activities. Project-based learning is often applied in the case of complex learning (i.e. which aims at making learners acquire various linked skills or develop their behaviours). In comparison to traditional learning, this type of learning relies on co-development, collective r...
