Recent events such as natural catastrophes or terrorism attacks have highlighted the necessity to ensure the structural integrity of buildings under exceptional events. Design requirements are proposed in some codes but are generally not satisfactory. In particular, it is not demonstrated that, even if these requirements are respected, a structure subjected to an exceptional event will really behave properly. A European RFCS project called “Robust structures by joint ductility” has been set up in 2004, for three years, with the aim to provide requirements and practical guidelines so as to ensure the structural integrity of steel and composite structures under exceptional events through an appropriate robustness. The investigations performed at the University of Liège, as part of this European project, are mainly dedicated to the exceptional event “loss of a column in a steel or steel-concrete composite building frame”; the main objective is to develop a simplified analytical procedure to predict the frame response further to a column loss. The development of this simplified procedure is detailed in two complementary PhD theses: the thesis of Demonceau J.-F. and the thesis of Luu N.N.H. Present paper describes experimental and analytical studies carried out in [Demonceau, 2008]. In particular, a simplified analytical procedure for the prediction of the global frame response when significant membrane forces develop further to a column loss will be described; it allows: (i) to predict the development of the catenary action in a frame with joints subjected to combined bending moment and tension loads and (ii) to compute the requested rotation capacity at the joint level according to the loads applied on the frame.

As more and more (principally free) Linux PC-distributions (commonly called “distro’s”) are appearing on the Internet, a lack is observed for handhelds’ Linux distributions, especially for Pocket PC’s (C). This article summarizes the most important (and recent) points about this fact, and tries to cover the whole subject with not-too-technical details, giving a basical overview about the different O.S. which are available for handhelds devices.

Deficits of suppression abilities are frequently observed in normal aging and Alzheimer's disease. However, few studies have explored these deficits in the two populations simultaneously using a large battery of tasks. The aim of the present study was to explore if the pattern of performance presented by elderly subjects and AD patients is in agreement with theoretical frameworks [Wilson, S.P., Harnishfeger, K.K., 1998. The development of efficient inhibition: Evidence from directed forgetting tasks. Dev. Rev. 18, 86-123; see also Nigg J.T., 2000. On inhibition/disinhibition in developmental psychopathology: views from cognitive and personality psychology and a working inhibition taxonomy. Psychol. Bull. 126, 220-246], distinguishing between the concepts of inhibition (a voluntary suppression of irrelevant information) and interference (an automatic suppression process occurring prior to conscious awareness). The results obtained demonstrated that (1) there is an alteration of the inhibitory process in normal elderly subjects; (2) inhibitory and interference resolution processes are quantitately less efficient in AD, since these patients present a correct performance only for information which leaves weak traces in memory.

Many studies have been written about children's development, and their behaviours during the phases they encounter before becoming adults. Thus, some clear links can be established between children's development and A.I. future trends. We here summarize the most important comparison characteristics. [less ▲]

Results made with the regional climate model MAR over 1958-2008 show a very high interannual variability of the Greenland ice sheet (GrIS) surface mass balance (SMB) modelled in average to be 330 +/- 130 km^3/yr. To a first approximation, the SMB variability is driven by the annual precipitation anomaly minus the meltwater run-off rate variability. Sensitivity experiments carried out by the MAR model evaluate the impacts on the surface melt of (i) the summer SST around the Greenland, (ii) the snow pack temperature at the beginning of the spring, (iii) the winter snow accumulation, (iv) the solid and liquid summer precipitations and (v) the summer atmospheric circulation. This last one, by forcing the summer air temperature above the ice sheet, explains mainly the surface melt anomalies. [less ▲]

Cette formation a été réalisée pour l'Institut de la Formation en Cours de Carrière (I.F.C.) et ciblait les enseignants de langues modernes. Dans le premier volet de cette formation, nous avons d'abord rappelé le cadre légal dans le domaine des langues en Communauté française de Belgique. Ensuite, nous avons comparé le programme de langues de la Communauté française à celui de l'Enseignement Libre et avons cherché à isoler un tronc commun. Enfin, nous avons présenté un canevas didactique de l'enseignement des langues étrangères qui intègre à la fois le modèle des situations-problèmes et celui de l'apprentissage expérientiel de D. Kolb. Dans le deuxième volet de cette formation, nous avons proposé aux participants de découvrir leur style d'apprentissage dominant. Dans le troisième volet, nous avons présenté deux plans de séquences didactiques basés sur ce canevas didactique expérientiel des situations problèmes. Enfin, nous avons clôturé cette journée de formation par une activité d'appropriation des acquis de la formation. [less ▲]

With the aim to study the impact of the mid-tropospheric circulation on the Greenland ice sheet (GrIS) surface melt simulated by the regional climate model MAR, we developed an automatic Circulation Type Classification (CTC) based on the 500hPa geopotential height from reanalyses over the period 1958-2008. This CTC shows that the dominant mode of the regional atmospheric summer variability around the GrIS is linked to the North Atlantic Oscillation (NAO) and that the surface melt anomalies are highly correlated to the general circulation. It explains notably why a record surface melt was observed during the summers 2007 and 2008. In addition, the climate conditions occurring the 27th August of 2003, where the GrIS temperature was 10°C higher than the normal, were the consequence of an almost unique 500 hPa circulation in the 50 last years.
