This paper considers a whole range of ORC applications, in terms of power (from the kW-scale to the multi-MW plants), heat source temperature (from 90°C to more than 300°C) or heat source nature (solar, biomass, waste heat recovery, geothermy, etc.). Five typical ORC applications are considered in terms of evaporating and condensing temperature. A screening of the most used ORC working fluids is performed, and their thermodynamics performances are compared with respect to the foreseen application. A detailed analysis of the most common expansion machines is then conducted, by comparing their respective operating maps for each fluid and for each application type. The considered expansion machines are the single-stage radial-inflow turbine, the screw expander, and the scroll expander, which are widely used in commercial applications and/or in scientific literature. The limitations of these machines are listed and considered to define an operating map for each considered fluid. Finally, the allowable power range is described with respect to the application and to the selected expansion device. [less ▲]

Expansion of the main auroral oval at Jupiter : evidence for Io’s control over the Jovian magnetosphere

In spring 2007, New Horizons' Jupiter fly-by provided a unique opportunity for the largest observation campaign dedicated to the Jovian aurora ever carried out by the Hubble Space Telescope. UV images of the aurora have been acquired on a quasi-daily basis from mid-February to mid-June 2007. Polar projection of the auroral emissions clearly show a continuous long-term expansion of main oval additionally to day by day variations. The main oval moved so much that the Ganymede footprint, which is usually located equatorward of the main emissions, has even been observed inside of it. Simultaneously, the occurrence rate of large equatorward isolated auroral features increased over the season. These emission patches are generally attributed to injections of depleted flux tubes. On 6th June, one of these features exceptionally moved down to the Io footpath. The Io footprint seemed to disappear while the footprint moved through this patch of emission. This disappearance is a unique case among all the UV images of the aurora acquired during the last 12 years. We suggest that all these changes seen in the Jovian aurora are evidence for a major reconfiguration of the magnetosphere induced by increased volcanic activity on Io. Indeed, New Horizons observed particularly intense activity from the Tvashtar volcano in late February 2007. Moreover, sodium cloud brightening caused by volcanic outbursts have also been seen in late May 2007. According to our interpretation, repeated volcanic outbursts beefed up the plasma torus density and its mass outflow rate. This caused the corotation breakdown boundary to migrate closer to Jupiter. Consequently, the main auroral oval moved equatorward. As heavy flux tubes move outward, sparsely filled ones should be injected into the inner magnetosphere in order to conserve the magnetic flux in this region. This phenomenon could explain the large number of injection signatures observed in May-June 2007. Such a cloud of depleted flux tubes probably disrupted the Io-magnetosphere interaction, leading to an abnormally faint Io footprint. [less ▲]

Submucous fibroids, polyps and dysfunctional bleeding are responsible for meno-metrorrhagia in women over 40 years of age. The authors describe the technique of hysteroscopic myomectomy and endometrial ablation using the Nd-YAG laser and the advantages of the preoperative use of GnRH agonist therapy. They report their results in a series of 746 patients treated for meno-metrorrhagia (366 cases of myomectomy and 380 cases of endometrial ablation). [less ▲]

Expected Design Space: a Bayesian perspective based on modelling, prediction and multi-criteria decision method

The Design Space (DS) is defined as the set of factors settings (input conditions) that provides results at least better than pre-defined acceptance limits. The proposed methodology aims at identifying a region in the space of factors that will likely provide satisfactory results during the future use of an analytical method or process in routine, through an optimization process. First, in a Bayesian framework, DS is derived from the joint predictive posterior distribution of the responses in a multivariate multiple regression problem using non-informative as well as informative prior distribution of the parameters. The case of DS in presence of highly correlated responses will be covered. Second, a multi-criteria decision is taken with respect to the pre-defined acceptance limits, aiming to identify the DS of any analytical methods or other processes. A strong link is made between acceptance limits and objective functions to optimize, using desirability functions and index. Examples based on high-performance liquid chromatography (HPLC) methods will be given, illustrating the applicability of the methodology with highly correlated and constrained responses. [less ▲]

Ma thèse se propose de démontrer les points suivants : 1. La pensée de Foucault doit être rapportée comme à sa condition de possibilité philosophique à l’émergence historique de la pensée critique telle qu’elle est associée au nom de Kant : j'ai étudié, dans leurs modalités diverses, « les kantismes de Foucault » ; 2. Pour le comprendre, il est de première importance de se concentrer sur les deux extrêmes de son parcours philosophique (1961-1969 et 1978-1984) ; 3. Ce postulat en implique un autre, de nature méthodologique : le choix de privilégier une reconstruction conceptuelle plutôt que chronologique de l’œuvre de Foucault ; ainsi peut-on mettre en évidence la cohérence très forte qui anime son parcours, sous les discontinuités évidentes qui l’affectent ; 4. La cohérence philosophique de la pensée de Foucault est liée à trois éléments : - l’unité d’une méthode, d’une certaine attitude de la pensée (nominalisme matérialiste réalisé dans la forme d’une archéo-généalogie) ; - l’insistance d’une question toujours posée dans le cadre de l’interrogation critique et d’une reprise partielle des motifs du transcendantal et surtout de la finitude ; cette question se résume du passage de la critique de la question anthropologique classique (Qu’est-ce que l’homme ?) à une enquête portant sur les modes d’être historiques du sujet (Que sommes-nous aujourd’hui ?) ; - la reprise constante de trois concepts qui font le cœur de la conceptualité philosophique moderne et qui forment chez Foucault un réseau à la relative systématicité : ceux d’expérience, de pensée et de critique ; 5. Le concept d’expérience est la pierre de touche de toute l’œuvre de Foucault : seule sa reconstruction patiente permet de saisir, de décrire et d’élaborer de manière satisfaisante la manière de penser qui est la sienne, dans son rapport critique à la pensée de Kant. Une fois rapportée à sa condition historique de possibilité, l'oeuvre de Kant, on comprend à la fois la nécessité conceptuelle de la proposition philosophique de Foucault mais aussi, par suite, les limites de sa proposition éthico-politique. C'est ce que j'ai nommé le nihilisme achevé ou positif de Foucault, la pure exigence d'une transformation micro-politique indéterminée et non-fondée de l'état de choses donné. Aller plus loin que celle-ci supposerait de reprendre la question philosophique directrice de Foucault - comment la transformation du sujet dans l’histoire vers un surcroît d’autonomie s’articule-t-elle à sa finitude radicale ? - aux abords de la dialectique, et en particulier en fonction de concepts critiqués par l'auteur, ceux de négativité et de totalité.
