Nul ne nie aujourd’hui l’intérêt d’associer les habitants et usagers au processus d’élaboration d’un projet de rénovation de leur quartier. Cependant, force est de constater que les délais et modalités de la participation classique ne permettent pas à certains types de public de s’exprimer et ne laissent pas le temps de la maturation et de l’appropriation. Il faut donc inventer des formes d’intervention qui permettent l’implication des habitants dans la ville dans la durée et qui participent à l’émergence d’une véritable culture de la participation. Community land trust, potager collectif, urbanisme temporaire, budgets participatifs… autant de projets qui permettent aux citoyens de devenir acteur et de tisser des liens intimes avec leur territoire.

The CoRoT satellite is revolutionizing the photometric study of massive O-type and B-type stars. During its long runs, CoRoT observed the entire main sequence B star domain, from typical hot β Cep stars, via cooler hybrid p- and g-mode pulsators to the SPB stars near the edge of the instability strip. CoRoT lowers the sensitivity barrier from the typical mmag-precision reached from the ground, to the μmag-level reached from space. Within the wealth of detected and identified pulsation modes, relations have been found in the form of multiplets, combination of frequencies, and frequency- and period spacings. This wealth of observational evidence is finally providing strong constraints to test current models of the internal structure and pulsations of hot stars. Aside from the expected opacity driven modes with infinite lifetime, other unexpected types of variability are detected in massive stars, such as modes of stochastic nature. The simultaneous observation of all these light curve characteristics implies a challenge for both observational asteroseismology and stellar modelling. The CoRoT space mission was developed and is operated by the French space agency CNES, with participation of ESA's RSSD and Science Programmes, Austria, Belgium, Brazil, Germany, and Spain. [less ▲]

Spurred by the spectroscopic and interferometric observations of rapidly rotating stars and the highly accurate pulsation data coming from asteroseismology space missions, theoreticians have spent many years developing models for such stars and studying their oscillations. This has led to the discovery of new phenomena and new types of pulsation modes. In what follows, a review is given of the different methods used to model the effects of rotation on stellar pulsations, as well as a description of these effects on inertial, gravito-inertial, r and acoustic modes.

The environments of both hot and cool stars are the sites of highly dynamic processes involving motion of gas and plasma in winds, flows across shocks, plasma motions in closed magnetic fields, or streams along magnetospheric accretion funnels. X-ray spectroscopy has opened new windows toward the study of these processes. Kinematics are evident in line shifts and line broadening, and also more indirectly through the analysis and interpretation of density-sensitive lines. In hot stellar winds, expanding-wind kinematics are directly seen in broadened lines although the broadening has turned out to often be smaller than anticipated, and some lines are so narrow that coronal models have been revived. Although X-ray spectra of cool stars have shown line shifts and broadening due to the kinematics of the entire corona, e.g., in binary systems, intrinsic mass motions are challenging to observe at the presently available resolution. Much indirect evidence for mass motion in magnetic coronae is nevertheless available. And finally, spectral diagnostics has also led to a new picture of X-ray production in accreting pre-main sequence stars where massive accretion flows collide with the photospheric gas, producing shocks in which gas is heated to high temperatures. We summarize evidence for the above mechanisms based on spectroscopic data from XMM-Newton and Chandra. [less ▲]

In this paper, we propose a technique based on 3D information (also called depth or range) for the detection of humans. First, a background subtraction technique operates to detect the silhouettes of humans and objects moving in the scene. Then, a machine learning algorithm is used to predict if a silhouette annotated with depth matches a human silhouette or not. The complete method is designed to cope with defects introduced during the segmentation step. Results, obtained on computer generated data, show that 3D depth data is a valuable information for detecting humans in that it improves over techniques based on binary silhouettes. In our experiments, we have reached an accuracy of 99.9% thanks to the depth information. [less ▲]

Un logiciel appelé EOL-OS a été développé dans le cadre des WP4 et 5 du projet « Windsteel : développement de solutions en acier pour la construction éolienne ». Cet outil informatique est essentiellement destiné au dimensionnement et à l’optimisation structurelle des éoliennes offshores de type monopile en acier. Toutefois, lors des développements effectués dans le courant du second semestre de l’année 2010, son application aux éoliennes onshore en acier a été rendue également possible. Ce document s’inscrit dans la continuité du rapport technique semestriel S1 de 2010. Il est laissé au lecteur le soin de se référer à ce dernier pour ce qui concerne la nomenclature utilisée pour décrire les structures étudiées ainsi que le détail des modules implémentés au terme des 6 premiers mois de 2010. La première partie du présent rapport concerne les développements effectués sur le logiciel EOL-OS et se focalise en particulier sur les modules implémentés dans le courant du semestre S2 de 2010. La seconde partie traite des résultats d’optimisation obtenus au terme des différentes simulations et tirent des conclusions générales sur le dimensionnement des structures support des éoliennes.

The objective of this technical note is to explore the applicability of nonlinear system identification techniques to spacecraft structures. To this end, numerical experiments carried out using the finite element model of the SmallSat spacecraft are used, without, however, having access to the model itself. The constraints imposed by the considered techniques for breadboard testing are also highlighted. [less ▲]
