Context: CoRoT is a pioneering space mission devoted to the analysis of stellar variability and the photometric detection of extrasolar planets. <BR />Aims: We present the list of planetary transit candidates detected in the first field observed by CoRoT, IRa01, the initial run toward the Galactic anticenter, which lasted for 60 days. <BR />Methods: We analysed 3898 sources in the coloured bands and 5974 in the monochromatic band. Instrumental noise and stellar variability were taken into account using detrending tools before applying various transit search algorithms. <BR />Results: Fifty sources were classified as planetary transit candidates and the most reliable 40 detections were declared targets for follow-up ground-based observations. Two of these targets have so far been confirmed as planets, CoRoT-1b and CoRoT-4b, for which a complete characterization and specific studies were performed. The CoRoTâ space mission, launched on December 27th 2006, has been developed and is operated by CNES, with contributions from Austria, Belgium, Brazil, ESA, Germany, and Spain. Four French laboratories associated with the CNRS (LESIA, LAM, IAS ,OMP) collaborate with CNES on the satellite development.

Aims: We present here the list of planetary transit candidates detected in the first long run observed by CoRoT: LRc01, towards the galactic center in the direction of Aquila, which lasted from May to October 2007. <BR />Methods: we analyzed 3719 (33%) sources in the chromatic bands and 7689 in the monochromatic band. Instrumental noise and the stellar variability were treated with several detrending tools, on which subsequently several transit search algorithms were applied. <BR />Results: Forty two sources were classified as planetary transit candidates and up to now 26 cases have been solved. One planet (CoRoT-2b) and one brown-dwarf (CoRoT-3b) have been the subjects of detailed publications.

With the release of CoRoT lightcurves of the Initial Run IRa01, 50 transiting planetary candidates have been published in a companion paper. About twenty of them were identified as binary stars from the CoRoT lightcurve itself. Complementary observations were conducted for 29 candidates, including ground-based photometry and radial-velocity measurements. Two giant planets were identified and fully characterized. Nineteen binaries are recognized, from which 10 are background eclipsing binaries in the CoRoT mask or triple systems, diluted by the main CoRoT target. Eight cases remain of unclear origin, one of them still being a planetary candidate. Comparison with simulations shows that the actual threshold of confirmed planet detection in this field does not yet fulfill the expectations, and a number of reasons are invoked, like the ranking process based on lightcurve analyses, and the strategy and limits of follow-up observations for targets fainter than magnitude 15. Based on data obtained at Observatoire de Haute Provence with SOPHIE and with HARPS on the ESO 3.6 m telescope at La Silla Observatory. The CoRoT space mission, launched on December 27th 2006, has been developed and is operated by CNES, with the contribution of Austria, Belgium, Brazil , ESA (RSSD and Science Programme), Germany and Spain.

Context: CoRoT is a pioneering space mission whose primary goals are stellar seismology and extrasolar planets search. Its surveys of large stellar fields generate numerous planetary candidates whose lightcurves have transit-like features. An extensive analytical and observational follow-up effort is undertaken to classify these candidates. Aims: The list of planetary transit candidates from the CoRoT LRa01 star field in the Monoceros constellation towards the Galactic anti-center is presented. The CoRoT observations of LRa01 lasted from 24 October 2007 to 3 March 2008. Methods: 7470 chromatic and 3938 monochromatic lightcurves were acquired and analysed. Instrumental noise and stellar variability were treated with several filtering tools by different teams from the CoRoT community. Different transit search algorithms were applied to the lightcurves. Results: Fifty-one stars were classified as planetary transit candidates in LRa01. Thirty-seven (i.e., 73 % of all candidates) are "good" planetary candidates based on photometric analysis only. Thirty-two (i.e., 87 % of the "good" candidates) have been followed-up. At the time of this writing twenty-two cases have been solved and five planets have been discovered: three transiting hot-Jupiters (CoRoT-5b, CoRoT-12b, and CoRoT-21b), the first terrestrial transiting planet (CoRoT-7b), and another planet in the same system (CoRoT-7c, detected by radial velocity survey only). Evidences of another non-transiting planet in the CoRoT-7 system, namely CoRoT-7d, have been recently found. [less ▲]

La planification comme énonciation d’un programme d’action à réaliser est au cœur des processus d’organisation et de leur normalisation. Souvent associée à la notion de formalisation rationalisatrice, la planification est aussi porteuse d’une injonction à communiquer. Elle n’exclut pas les situations d’interactions et d’ajustement en face à face ni les pratiques discursives. Bien au contraire, elle repose sur l’articulation de plusieurs formats d’information, de registres d’action et de régimes d’engagement. Basée sur une enquête de type ethnographique menée au cours d’une recherche doctorale, la présente communication s’attache à décrire en quoi ils participent à la mise en convergence d’agencements sociotechniques qui incluent et contribuent à la performance de ce programme d’action.

Emergency preparedness is essential in our Western societies. It serves to reassure the community on the measures taken for its safety and to organise the activities of all those working in the field. However, emergency planning procedures are under pressure as the result of a dual trend: the emergence of new risks and a more complex institutional setting. [less ▲]

Cet article décrit l'algorithme BOP (de l'anglais ``Bayesian Optimistic Planning''), un nouvel algorithme d'apprentissage par renforcement Bayésien indirect (c'est à dire fondé sur un modèle). BOP étend l'approche de l'algorithme OP-MDP (de l'anglais ``Optimistic Planning for Markov Decision Processes'', voir [Busoniu2011,Busoniu2012]) au cas où les probabilités de transitions du MDP sous-jacent sont initialement inconnues, et doivent être apprises au travers d'interactions avec l'environnement. Les connaissances sur le MDP sous-jacent sont représentées par une distribution de probabilités sur l'ensemble de tous les modèles de transitions à l'aide de distributions de Dirichlet. L'algorithme BOP planifie dans l'espace augmenté état-croyance obtenu par concaténation du vecteur d'état avec la distribution postérieure sur les modèles de transitions. On montre que BOP atteint l'optimalité Bayésienne lorsque le paramètre de budget tend vers l'infini. Quelques expériences préliminaires montrent des résultats encourageants. [less ▲]

There is a growing imbalance between modes of transport in the European Union. The increasing success of road results in an ever worsening congestion, more environmental nuisances and accidents. That’s why one of the objectives of the European Common Transport Policy is to restore the balance between modes of transport and to develop intermodality. Among the various types of intermodal transport this doctoral dissertation is concerned by rail-road combined transport for which the terminals are embedded in a hub-and-spoke network. This kind of topology can reduce the transportation costs by consolidations at the hubs. The proposed method uses the flows of commodities and their geographic spreading as input to determine a set of good potential locations for transfer container terminals. This set can further be used as input for an iterative procedure based on both the p-HMP and the multi-modal assignment in order to identify the optimal locations for such terminals in Europe. This procedure takes into account the variation of the transshipment cost according to the number of containers that could be transshipped. [less ▲]

A three-dimensional (3D) non-linear high-resolution hydrodynamic model coupled to a coastal plankton ecosystem model is used to estimate the impact of hydrodynamic processes on the evolution of the spring phytoplankton bloom in the vicinity of a submarine canyon. Model results for the plankton distribution showed a clear 3D character around and in the canyon, with large horizontal and vertical gradients, induced by the hydrodynamic constraints. Phytoplankton concentrations were significantly larger all along the slope domain with maximum values obtained over the canyon. Upwelling of deep water rich in nitrate takes place both upstream (with respect to the current direction normal to the central axis of the canyon) and downstream of the canyon enhancing primary production. As phytoplankton-rich water enters into the western part of the canyon it is downwelled and trapped by the cyclonic circulation leading to accumulation of phytoplankton biomass there. The effect of wind events was to induce an upward nitrate flux into the upper layer through vertical turbulent diffusion, allowing the start of a short-live phytoplankton bloom. Maximum surface nitrate concentrations were found along the slope and particularly upstream and downstream of the canyon just after the wind stopped. Enhanced turbulent diffusion combined with upwelling motion in these areas resulted in larger upward nitrate transports, further enhancing primary production. (c) 2006 Elsevier Ltd.
