The present paper first describes briefly the hydrodynamic model WOLF 2D. Secondly, the simulation of the Malpasset dam break enables to highlight the effectiveness of WOLF 2D. Lastly, the model is applied to simulate the flood generated by the hypothetic collapse of a large concrete dam, which would induce three dam breaks in cascade. [less ▲]

The numerical optimization process of the system of hydroelectric power stations installed on a 60 km long section of the rivers Amblève and Warche in Belgium is presented in detail. The river network is modelled in quasi-2D using real natural topographic data on almost 1,100 finite volumes. In a first step, the hydrological balance is closed using a numerical solver and roughness coefficients are calibrated from water level and discharge field measurements. Secondly, the hydroelectric production is maximised by an automatic calibration of the parameters of the hydrograph released in the network at the upstream dam. This approach leads to a substantial gain in hydroelectric production, brings significant financial benefits and deals with all management and security criteria of the river network. [less ▲]

Recent events such as natural catastrophes or terrorism attacks have highlighted the necessity to ensure the structural integrity of buildings under exceptional events. Accord-ing to Eurocodes and some different other national design codes, the structural integrity of civil engineering constructions should be ensured through appropriate measures but, in most of the cases, no precise practical guidelines on how to achieve this goal are provided. A European RFCS project entitled “Robust structures by joint ductility” has been set up in 2004, for three years, with the aim to provide requirements and practical guidelines ensuring the structural integrity of steel and composite structures under exceptional events through an appropriate robustness. In particular, one substructure test simulating the loss of a column in a composite building has been performed at Liège University. Present paper describes ana-lytical, numerical and experimental investigations carried out at Liège University as part of this European project. [less ▲]

The variational inverse model (VIM) for data analysis was already shown to be statistically equivalent to objective analysis (OA) provided the covariance function for the OA and the VIM reproducing kernel are identical. The VIM, however does not allow a direct derivation of the error field associated with the analysis. The purpose of the paper is to extend the one to one correspondance between the two analysis shemes by proposing a heuristic statistical error expression for the VIM. The numerical efficiency on analysis and error map generation of both methods is compared on quasi-synoptic and climatological data sets. It is shown that the VIM analysis and error map generation offers interesting numerical skills in both case studies. [less ▲]

En premier lieu, le numéro de novembre traite de la place du numérique dans l’aide multilatérale en matière d’industries culturelles, se penchant sur le programme ACPCultures+ financé par l’Union européenne (UE) et géré par le Secrétariat du Groupe des pays ACP (Afrique, Caraïbes, Pacifique). En deuxième lieu, nous traitons de l’évolution récente des négociations commerciales, et surtout du mandat du Conseil européen ‐ rendu public au début d’octobre ‐ pour les négociations pour un partenariat transatlantique entre l’UE et les États‐Unis. En troisième lieu, nous mettons l’accent sur un grand nombre de questions centrales de la gouvernance mondiale de la culture, telles que la Déclaration de Florence sur le lien entre le développement et la culture, le rapport de la Motion Picture Association of America (MPAA) au sujet des marchés notoires en termes de piratage numérique et physique, le rapport sur l’égalité des genres et le secteur culturel, ainsi que le rapport sur la contribution des industries créatives dans l’économie européenne.

The file and the Database Mertens-Pack3 of the CEDOPAL of the University of Liège (Belgium) complement each other with a unique collection to the world, begun more than forty years ago with the Professor Paul Mertens, and ceaselessly enriched, more than 8000 photos of literary papyri, in black and white for the greater part, accompanied with their archives, that is, essentially, the enormous exchanged correspondence, since the sixties, between the CEDOPAL and the conservators of papyri. To perpetuate its collection of reproductions and give it more easily to the international scientific community, the CEDOPAL began since July, 2003, by means of a " Grant 2003 " of the International Association of Papyrologues, to digitize every photography of papyrus and to archive these images in a specialized database, which also includes informations from archival documents.

Owing to the establishment of a procedure aiming at a reduction of the medical supply (numerus clausus), the French Community of Belgium had decided to introduce, at the end of the third year of medical studies (third candidature), a procedure of selective attribution of the certificate allowing for a unlimited medical practice. We assessed the predictive value of the results obtained during and at the end of the first candidature (first year of medicine) for the attribution of this certificate. We studied the results of the 225 students enrolled in the first candidature in medicine at the University of Liege during the academic year 1997-1998, and we correlated them to the subsequent attribution (1999-2000- and 2000-2001) of the certificate. The success of the first candidature in the first or second session is an important predicting factor towards the reception of the certificate. A non-authorization to continue the studies in medicine in case of failure in the first session or a non-authorization to repeat the first candidature in case of failure in the second session would have, respectively, a negative predictive value (NPV) of 91.9% and 97.4% and would allow to restream 111 students at the end of the first session or 39 students at the end of the first candidature. The results of the preliminary assessments mode during the month of January are also highly predictive of the chances to get the certificate. Among the 160 students who have not successfully passed a minimum of 3 exams, only 14 students obtained the certificate. The restreaming of those students would correspond to a NPV of 91.2%. Students who were not successful in a minimum of 2 exams would have less than 5% chance to obtain the certificate. In this case, 109 students would be restreamed (NPV = 95.4%). In conclusion, the selection of the students who will obtain, at the end of the third year of medicine, the certificate allowing them for an unlimited medical practice is obtained, in a large proportion, during the first candidature and especially after the session of January. In view of those results and considering the decree abolishing the selection at the end of the third year of medical studies, one could argue about the appropriateness of the current procedure, chosen by the French Community of Belgium, compared to other solutions prioritising an earlier selection of the future doctors.
