TV show structuring consists in breaking down a program into several sequences (interviews, musical performances, film excerpts, etc.) and in retrieving for each of these segments high-level knowledge often refered to semantic content. The focus here is on two particular tasks: the detection of musical performances, i.e. the segments where artists are performing live music, and the identificati...

In order to obtain political interest in road safety problems and to learn from other countries’ ‘good practices’, it is often helpful to compare one’s own safety situation with that of other countries. In a number of projects tools have been developed for such comparisons. These tools range from simple ratings of countries on their safety outcomes, such as the annual number of fatalities per c...

The gardener picks up a fir cone and rolls it through the quiet room straight towards a small child in the audience. Either the child leaves the fir cone lying where it is, or perhaps picks it up. Perhaps the child will later roll the fir cone on towards another child. Or make a gravel track around its mother. Maybe the child kneels down beside a bed full of branches and twigs and feels the mat...

Background in Computing. Machine learning and data mining techniques have been widely applied to expressive music performance, focusing on finding general principles underlying expressive 'deviations' from the musical score in terms of timing, dynamics and phrasing. These principles aim to model aspects of renditions in a formal quantitative and predictive way (Widmer & Goebl, 2004). Modelling ...

Résumé Des travaux récents visent l’optimisation des opérations de communication collective dans les environnements de type grille de calcul. La solution la plus répandue est la séparation des communications internes et externes à chaque grappe, mais cela n’exclut pas le découpage des communications en plusieurs couches, pratique efficace démontrée par Karonis et al. [10]. Dans les deux cas, la...

To repeat a grade in elementary school or junior-high school is the most direct indicator of early performances at school in France. At the end of junior high-school, about 40% of French adolescents have been held back a grade and our paper provides estimates of neighborhood e¤ects on this indicator of performances at school. We develop three di¤erent strategies in order to address the endogene...

The low temperature radiant systems are very complex because they involve different mechanisms of heat transfer: heat conduction through the walls, heat convection between the heating panel and the indoor air, heat radiation between the heating panel and the surrounding areas, and the heat conduction between the floor and the ground. The main essence of the low-temperature air systems is to pro...

The literal performance of the symbols contained in a traditional score is not enough to produce expressive music. Human interpreters use musical knowledge that is not explicitly represented in it. This paper presents a knowledge-based approach to introduce expressiveness to the performance of a score by calculating dynamics and tempo envelopes of the piece, combining implicit musical knowledge...

Learning agents can autonomously improve both knowledge and performances by using learning strategies. Recently, an approach based on a cloning process, called EVolutionary Agents (EVA), has been proposed to obtain more effective recommendations, generating advantages for the whole agent community through individual improvements. In particular, users can substitute unsatisfactory agents with ot...

Though fatigue and sleepiness at the wheel are well-known risk factors for traffic accidents, many drivers combine extended driving and sleep deprivation. Fatigue-related accidents occur mainly at night but there is no experimental data available to determine if the duration of prior driving affects driving performance at night. Participants drove in 3 nocturnal driving sessions (3-5 am, 1-5 am...
