A simplified model for the prediction of the steady-state outflowthrough a breach in an inland dike is presented. It consists in the application of the mass and momentum conservation principles to a macroscopic control volume. A proper definition of the shape of the control volume enables to take the main characteristics of the flow into account and thus to compensate for the extreme simplification of the spatial representation of the model. At the breach, a relation derived from the shallow-water equations is used to determine the direction of the flow. Developments have been guided by numerical simulations and results have been compared to experimental data. Both the accuracy and the domain of validity of the simplified model are found satisfactory. [less ▲]

Cette étude est consacrée à la formation du graphite dans des fontes à haute teneur en chrome (8%) et spécialement à la détermination des conditions de formation de graphite secondaire par des traitements thermiques adaptés. La solidification de la fonte étudiée a été examinée par analyse thermique différentielle (ATD). Les effets d'un traitement à haute température ont été examinés à la fois par calorimétrie et dilatomètre différentielle. Le graphite primaire se forme vers 950°C. Le graphite secondaire précipite sur le graphite primaire lors du traitement de déstabilisation de l'austénite à haute température. La forme et la quantité de graphite secondaire dépendent de la température de traitement. [less ▲]

The interest of small additions of Cr (< 3 wt %) and Mo (~ 0.2 wt %) in steels for automotive and bearing applications has been recently highlighted. The microstructure of these steels is primarily based on the bainitic phase. In order to optimize their microstructure and their mechanical properties, it is, therefore, of primary importance to gain a better understanding of the influence of Cr and Mo on austenite decomposition in varying temperature regimes with a particular attention to the transition between ferrite, bainite and martensite formation. In the present work, dilatometry, combined with detailed microstructural characterisation, is used in order to obtain a full view of transformation processes and kinetics in two medium-carbon steels with and without Cr and Mo additions.

Cluster analysis is a set of multivariate procedures to detect natural groupings in data. The objective of those methods is to group a set of objects in such a way that objects in the same group (called cluster) are more similar to each other than to those in other groups. Organizing data into sensible groupings arises naturally in many scientific fields as psychology, biology, statistics, bioinformatics, marketing, and so on. However, the obtained solution is not unique and it strongly depends upon the analyst’s choices. Representation and normalization scheme, selection of distance measures and a clustering algorithm, choice of the number of clusters and their interpretations are all subjective choices which change the final output. Those decisions are mainly guided by the purpose of grouping, domain knowledge and the individual data set. Therefore, cluster validity assessment should be performed to evaluate the validity of the obtained clusters and to find the partitioning that best fits the underlying data. I provide a brief overview of clustering, summarize well known algorithms, and discuss the major challenges and key issues in performing clustering analysis. [less ▲]

Je discute ici le projet diltheyen d'une "fondation psychologique des sciences de l'esprit". Je suggère que ce projet peut être rapproché d’un certain programme épistémologique baptisé "empirisme psychologique". L’hypothèse qui se trouve à la base de l’empirisme psychologique est la suivante : l’expérience interne, psychologique, est la source des concepts au moyen desquels nous pouvons penser et connaître le monde. Après avoir brièvement reconstruit le programme diltheyen en ce sens, j'examine deux objections qui ont été soulevées contre lui: l'objection néokantienne (Windelband, Rickert) et l'objection psychologique (Ebbinghaus, Stumpf). La seconde, selon moi, met en évidence une difficulté réelle du projet de Dilthey: la "connexion structurelle de la vie" dans sa totalité peut difficilement être considérée comme "donnée" dans l'expérience interne, ainsi que l'affirme Dilthey. Je soutient donc que le programme de l'empirisme psychologique peut être poursuivi à condition de le débarrasser de cette thèse problématique. [less ▲]

Using a vector vortex coronagraph behind the 1.5 m well-corrected subaperture (WCS) at Palomar, we detected a second object very close to epsilon Cephei, a δ Scuti F0 IV star. The candidate companion, ~50 times fainter than epsilon Cephei, if physically associated, is a late-type K or early M star, and lies at an angular separation of 330 mas, or 1.1 λ/D for the WCS, making it the smallest angle detection ever realized with a coronagraph in terms of λ/D units. The projected separation of the putative companion is ~8.6 AU, most likely on a highly eccentric orbit. The recently detected near-infrared excess is thus likely not due to hot dust. Moreover, we also show that the previously reported IRAS 60 μm excess was due to source confusion on the galactic plane. [less ▲]
