Our Working Group (WG) studies massive, luminous stars, both individually and in resolved and unresolved populations, with historical focus on early-type (OB) stars, A-supergiants, and Wolf-Rayet stars. Our group also studies lower mass stars (e.g., central stars of planetary nebulae and their winds) which display features similar or related to those present in massive stars, and thus may improve our understanding of the physical processes occurring in massive stars. In recent years, massive red supergiants that evolve from hot stars have been included into our activities as well. We emphasize the role of massive stars in other branches of astrophysics, particularly regarding the First Stars, long duration Gamma-Ray bursts, formation of massive stars and their feedback on star formation in general, pulsations of massive stars, and starburst galaxies.

S’il est un élément précoce de la socialisation politique des jeunes Belges, c’est la connaissance de l’obligation de voter dans ce pays. Peu de Belges ignorent, en effet, que le vote y est obligatoire et donc qu’une obligation de se rendre aux urnes, sous peine de sanctions – généralement peu ou mal connues –, incombe à chaque électeur du Royaume, même si dans les faits tous ne participent au scrutin. Pourtant, le vote obligatoire n’est pas une caractéristique commune des systèmes électoraux à travers le monde. À ce jour, on ne retrouve une telle obligation, assortie ou non de sanction, que dans trente et un États ou partie d’État. La Belgique fut précurseur en la matière et, même si ce pays ne s’est pas détourné du vote obligatoire en plus de cent ans d’existence, cette obligation continue de susciter un véritable débat. Dans la première partie de ce chapitre, nous revenons sur l’introduction du vote obligatoire en Belgique en présentant les arguments de ce débat. La deuxième partie aborde les principes et les sanctions consacrés par le droit positif tandis que la troisième partie explore les conséquences politiques du vote obligatoire. Tout naturellement, la conclusion de ce chapitre se penchera sur son avenir en Belgique. [less ▲]

In the numerical analysis of structures in fire, the material models that are used have important implications on the global behavior of the structure. In concrete, a particular phenomenon appears when subjected to high temperatures: the transient creep strain. Models integrating explicitly a term for transient creep strain have been proposed in the literature but, in the current Eurocode 2 model, there is no explicit term for transient creep strain. This phenomenon is included in the Eurocode 2 model, but it is implicitly considered in the mechanical strain term. A series of experimental fire tests on axially restrained concrete columns subjected to heating and cooling has been recently performed at South China University of Technology and described by Wu et al. (Fire Technol 46:231–249). In the original paper, it was shown that using the implicit model of Eurocode 2, the behavior of the columns cannot be simulated properly, especially during the cooling phase. The objective of the present paper is to perform again the fire tests simulations using a new formulation of the Eurocode 2 model that contains an explicit term for transient creep. In the first part of the paper, the explicit formulation of the Eurocode 2 model is presented. In the second part, the fire tests are modeled with the software SAFIR using, on the one hand, the implicit Eurocode model and, on the other hand, the new explicit model. It is shown that the transient creep model has significant implications on the global behavior of structural concrete members, as the residual axial load sustained by the columns at the end of the fire can differ by up to 25% of the initial applied load depending on the transient creep strain model that is used for the calculation. The experimental behavior is better matched with the new explicit model than with the current Eurocode model. Particularly, the results given by the Eurocode model during the cooling phase are unconservative as the residual axial load is overestimated. Finally, it is explained why, on the basis of an example, in a performance-based approach, these results can have important implications on the global fire resistance of a structure. [less ▲]

In his writings concerned with biopolitics Foucault gives the concept of population a central place and means to find its arising at the crossroads of several types of discourse : particularly about species and the public. The genealogy of this bifocal concept is in keeping with some aspects of Canguilhem’s epistemological approach to the regulation of milieus, following his work on scientific ideology. Not only does such a parallel enable us to bring out the critical use of biopolitical concepts, it also leads us to examine the technological sequence which has made it possible for the concept of population to be determined. Such a sequence is articulated in three moments – utopia, practice, theory – which enable us to account for the evolution of the technology of police. [less ▲]

Nowadays, image processing and GIS tools are more accessible and available to all. Most of diachronical or historical studies use the image geometric correction with several documents like old maps, plans or aerial photographs. They are usually based on low-order polynomial equation to perfom these kinds of simplistic uses. Most of commercial softwares provide us a total or by ground control points RMSE but they don’t offer a overview of the spatial error distribution. More this does not guarantee that its significance for the other points of the image. Do not consider these errors can lead to erroneous observations and misinterpretations like historical moving streams or bank erosion rate. Using a least square adjustment (LSA), allow to recalculate the transformation equation from the pairs of control points coordinates. Assuming that residuals are spatially auto-correlated, we can build error vectors whose direction and magnitude symbolize the error at each point of the image. By another way, LSA manage the precision during transformation process by using a stochastic model in addition of the mathematical model during the transformation. This gives us variance on parameters of the transformation. Knowing the precision of all elements and variance/covariance matrix on transformation parameters, we apply variance propagation on the model. As an output, we obtain confidence ellipses on each transformed points, thus a spatial distribution of error for the entire image. Moreover, this leads us to determine statistically if observed movement are significant or not. The represent error is a complex problem that cannot be solved with a quick fix. In this work, we present an interesting example of using well-known topographic methods to solve image processing problems. [less ▲]

Finite element models accurately compute the mechanical response of bone and bone-like materials when the models include their detailed microstructure. The aim of this paper is to develop and validate a biomechanical model for deer antler cancellous bone tissue based on X-ray microtomographic images. In order to simulate the mechanical behavior under compressive load using a finite element model, images obtained by X-ray microtomography were exported into Metafor, which is an non-linear finite element software initially developed at University of Liège for metal forming processes. This software has recently found biomedical applications. The ultimate goal is to compare model predictions with the mechanical behavior observed experimentally using the Skyscan material testing stage under compression mode. The creation of the biomechanical model mesh from segmented μCT images, its integration into the software Metafor and the simulation of a compression test are described in this paper. [less ▲]

This paper presents an overview of the case law of the ECJ in relation to Regulation 2201/2003. The focus is on cases decided by the ECJ and by French and Belgian courts, with a few reference made to court practice in England. Cases are presented and discussed in relation to the various provisions of the Regulation to which they relate. For each case, an abstract is included, followed by (critical) comments. This overview appeared in a book presenting the main European regulations dealing with European procedural law (jurisdiction of courts, recognition and enforcement of foreign judgments). The book is part of a series edited by Prof. Georges de Leval (University of Liège), which collects court practice in relation to procedural law. [less ▲]
