Probabilistic graphical models (PGM) efficiently encode a probability distribution on a large set of variables. While they have already had several successful applications in biology, their poor scaling in terms of the number of variables may make them unfit to tackle problems of increasing size. Mixtures of trees however scale well by design. Experiments on synthetic data have shown the interest of our new learning methods for this model, and we now wish to apply them to relevant problems in bioinformatics. [less ▲]

Recent research in structural fire engineering has shown that concrete or composite building structures can develop unexpected modes of strength when subjected to fire. Under certain conditions, a structure will present a robust behavior that can dramatically increase its fire resistance compared to the fire resistance calculated by a predictive approach. An example of such robust behavior is the membrane action that can be developed by a structural slab in fire. However, the numerical simulation of such behaviors requires the development of reliable and accurate multiaxial constitutive relationships for modelling the behavior of concrete. This presentation is based on the work performed by the author during a six month research stay at CEA Saclay, in the team of Alain Millard. The aim of the research stay was to develop a concrete multiaxial model that can be used for the numerical analysis by the finite elements method of concrete structures in fire. To be able to accurately simulate the structural behavior during every phases of a natural fire, the concrete model includes plasticity and damage phenomena. The main features and parameters of the model are presented and its implementation in the softwares SAFIR and CAST3M is briefly discussed. Then, a few applications are given and the presentation ends with a comment on the remaining issues and perspectives. [less ▲]

The ILMT is a four meter diameter liquid mirror telescope built in Liège by a collaboration of astronomers from Canada, India, ROB and ULg. In January 2011, for the first time, the mirror was tested with liquid Mercury. After reminding liquid mirror basics, we present the different phenomenons that may affect the mirror surface quality. We then present a method created to test the ILMT surface quality and we summarize the course of the recent mercury tests. [less ▲]

We present photometric studies of the gravitationally lensed QSOs UM673 and HE0435. Concerning the doubly imaged quasar UM673, we are presently carrying out a preliminary analysis of the observations. Regarding the quadruply imaged quasar HE0435, the analysis is complete. The variations of this lensed quadruplet show that the source is intrinsically variable. Furthermore, one component is also very likely affected by microlensing. The significant color variations observed for the four lensed images are also consistent with variations produced by the source, and not by the lens. Our flux and color analysis are based upon different methods (image subtraction and PSF fitting) for studying the multi-band variability. [less ▲]

L’avancée des recherches en historiographie carolingienne a conduit ces dernières années à la remise en cause des circonstances de l'avènement du maire du palais Pépin III à la tête du royaume franc. Non seulement la sincérité des sources carolingiennes mais certains détails de la cérémonie admis de longues dates ont été mis en doute. De récentes interprétations suggèrent que les circonstances du changement de dynastie de 751 furent bien différentes de celles qui sont traditionnellement enseignées. Cette communication proposait un passage en revue de l’ensemble des témoignages de l’usurpation du trône mérovingien par Pépin III rédigés du vivant de Charlemagne. Avant d'envisager les différentes versions des événements séparant la mort de Charles Martel de l’onction de 754 véhiculées par les « petites annales carolingiennes », l'auteur revient sur les quatre textes traditionnellement invoqués pour traiter cette question : la continuation de Frédégaire, les Annales regni Francorum (annales royales), le liber pontificalis, et la clausula de unctione Pippini.

This presentation introduces two different research projects dealing with 3D audio for 3D-stereoscopic movies. The first project “3D audio acquisition for real time applications” studies the best method for acquiring a full 3D audio soundscape on location and for processing it in real-time for further reproduction. The second project “Adding 3D sound to 3D cinema” is aimed towards the study of reproducing a 3D soundscape consistent with the visual content of a 3D-stereoscopic movie. These projects are linked together since they present both ends of the 3D audio chain. They are conducted as part of the “MEDIATIC – 3D MEDIA” project, which concerns the production, the processing, and the exploitation of rich audiovisual content, with a specific focus on 3D video imagery.

Gate (Geant4 Application for Tomographic Emission), based on Monte Carlo methods allows simulation of full PET-acquisition processes. Gate results for one of CRC’s tomographs, the HR+, are in good agreement with real data, with a maximum mean difference of 6%. Monte Carlo simulations are highly CPU-consuming, so we had to parallelize simulations on the recently setup cluster. In order to use Gate properly on the cluster, the optimal number of CPU was determined. We studied the performances of the small animal microPET FOCUS 120 in terms of counting rate capability (NECR index) for comparison with future simulated results. [less ▲]

Expanded Metal is a second product made from metal sheet by first cuttings, cold-drawing, and finally by being flattened. A research is under way at University of Liege with the aims at determining the mechanical properties of this type of material under seismic excitations. In view of their application to building seismic retrofitting and upgrading, three approaches: analytical models, numerical simulations and experimental investigations, have been used to characterize the mechanic behavior of expanded metal sheets which are monotonically and cyclically loaded in shear. Nonlinear numerical simulations and experimental tests are used to determine the hysteretic behavior of expanded metal shear panels (EMSP), and an analytical model is then proposed, with the aims of using that to study the influence of such EMSP when they are used to retrofit and upgrade reinforced concrete moment resisting frames (RC-MRF). Many RC-MRF are then designed in two cases: (1) in accordance with only Eurocode 2 and (2) in accordance with both Eurocode 2 and Eurocode 8. Capacities of such designed structures are evaluated by using nonlinear static analysis (Pushover) and nonlinear time history analysis under different types of soils and ground motions. The efficiency of using EMSP is evaluated in terms of strength, stiffness and energy dissipation. Additionally, with the presence of EMSP, some unfavorable behavior of RC-MRF under seismic action such as soft story mechanism can be prevented. [less ▲]

Electrical resistivity tomography is a geophysical method widely used for salt water intrusion studies, thanks to its ability to detect salinity contrasts. In this context, boreholes are often available to improve the interpretation of inverted models. The main objective of this study is to incorporate a priori information contained in borehole data to constrain the geophysical inversion with a geostatistical constraint based on the variogram. A synthetic benchmark showed that the choice of the prior model played a great role in the inversion process, especially in low sensitivity zones. The use of simulations conditioned with borehole data costs a lot of time because it is necessary to run several inversions to obtain a mean solution. The methodology was applied to artificial salt water infiltrations in the Westhoek nature reserve. In this case, a homogeneous prior model deduced from borehole data seemed judicious. Inversion results enabled to determine the extension of the salt water plume laterally, in depth, but also in terms of total dissolved solid content (TDS). These observations are in agreement with the hydrogeological situation of the site. A comparison with borehole data showed that the results are much more satisfying than a traditional smoothness constraint used as a regularization tool. [less ▲]
