This paper presents a multi-scale framework for the failure of periodic quasi-brittle thin planar shells. The failure behavior of textured or periodic heterogeneous materials is strongly influenced by their mesostructure. Their periodicity and the quasi-brittle nature of their constituents result in complex behaviors such as damage-induced anisotropy properties with localization of damage, which are difficult to model by means of macroscopic closed-form constitutive laws. A computational homogenization procedure is used for the in-plane and out-of-plane behavior of such planar shells, and is combined with an acoustic tensor-based failure detection adapted to shell kinematics to detect the structural-scale failure. Based on an assumption of single period failure, the localization of damage at the structural scale is represented by means of mesostructurally informed embedded strong discontinuities incorporated in the macroscopic shell description. A new enhanced scale transition is outlined for shell failure, based on an approximate energy consistency argument to objectively upscale the energy dissipation. The corresponding multi-scale framework results are compared with direct fine-scale modeling results used as a reference for the case of masonry, showing good agreement in terms of the load-bearing capacity, of failure mechanisms and of associated energy dissipation. © 2010 John Wiley & Sons, Ltd.

In this report written for the Utrecht Congress of the International Academy of International Law, I review the position of same sex couples, be they married or bound by a partnership, under Belgian law. Specific attention is devoted to the treatment under Belgian law of cross-border couples (couples with other nationalities than Belgian nationality, or whose habitual residence is or was established outside Belgium). Among the questions studied two stand out : first the question of who can validly conclude a same sex marriage or enter into a partnership in Belgium and second the issue of the recognition in Belgium of same sex marriages or partnerships concluded abroad.

Les couples et les familles avec partenaires et parents LGBT (lesbiens, gays, bisexuels, transgenres) sont souvent passés sous silence dans l’approche systémique. Ce silence trouve ses racines dans l’hétérocentrisme qui a influencé la définition de couple, de famille et de relations familiales ainsi que de leur « normalité » vs « pathologie ». Qu’on soit chercheur ou clinicien, il est intéressant de prendre en considération l’impact de l’homophobie, de l’hétérosexisme, de l’hétéronormativité dans la vie quotidienne de ces couples, de ces familles et de leurs enfants. En particulier dans la consultation clinique, il semble important d’en évaluer leur degré de stress, d’ambiguïté relationnelle, d’homonégativité intériorisée ainsi que de support social. Nous réfléchirons aussi sur les atouts et les limites des modèles majeurs de thérapie de couple et de famille dans le travail thérapeutique ainsi que sur la nécessité d’envisager des pistes dans la formation du futur thérapeute sur les questions LGBT. Formation qui pourrait être basée sur le modèle de la diversité comme modèle inclusif des différences familiales et relationnelles contemporaines. [less ▲]

A primitive equation model and a statistical predictor are coupled by data assimilation in order to combine the strength of both approaches. In this work, the system of two-way nested models centred in the Ligurian Sea and the satellite-based ocean forecasting (SOFT) system predicting the sea surface temperature (SST) are used. The data assimilation scheme is a simplified reduced order Kalman filter based on a constant error space. The assimilation of predicted SST improves the forecast of the hydrodynamic model compared to the forecast obtained by assimilating past SST observations used by the statistical predictor. This study shows that the SST of the SOFT predictor can be used to correct atmospheric heat fluxes. Traditionally this is done by relaxing the model SST towards the climatological SST. Therefore, the assimilation of SOFT SST and climatological SST are also compared. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]

We propose a way to couple field equations for quasistatics in a bounded domain-where electromagnetic phenomena are assumed to be confined-with circuit equations. The algebraic equations describing eddy-current problems are obtained by means of a discrete geometric formulation A-chi, based on the circulation of the magnetic vector potential A and a scalar potential chi.

Flow velocity and sedimentation patterns were investigated experimentally and numerically in shallow rectangular reservoirs with different asymmetric locations of the inlet and outlet channels. Velocity fields were measured in the entire reservoir, both for clear water flow and with suspended sediments. Thickness of sediment deposits were mapped in the whole reservoir by means of a laser light method. In one of the studied geometric configurations, injection of suspended sediments led to a complete change in the observed flow field. Experimental results were compared with numerical simulations performed with the depth-averaged flow model WOLF 2D, using a depth-averaged k-e turbulence model. The simulations lead to accurate predictions of the velocity profiles and the change in flow pattern as a result of sediment deposits was successfully reproduced. [less ▲]

A correct modelling of thin-walled members behaviour requires a due account for global lateral buckling, but also for local buckling of the profile walls. In this perspective, a special beam element is developed. The displacement field of this element allows to model any in plane global behaviour (tension, compression, in plane bending, in plane column buckling…) as well as the local buckling of the profile walls. The element is developed for bifurcation analysis (computation of critical loads) as well as for non linear analysis, including coupling between global and local phenomena. [less ▲]

This article reports the coupling of a building energy simulation (BES) made with TRNSYS with a computational fluid dynamics (CFD) simulation made with ANSYS FLUENT and its application to a typical Belgian two-storey house. The coupling scheme developed in this study aims to improve the overheating prediction for buildings. This phenomenon is becoming increasingly frequent in Northern Europe due to increased insulation and a lack of sun protection and natural cooling strategies. Complementary contributions of the two numerical approaches are underlined and used to obtain accurate results in an acceptable computing time, even in a thermally stratified room. The space and time coupling is discussed to obtain an optimised tool in which BES is in charge of the primary portion of the effort, while CFD intervenes punctually on one room of interest. The numerical results are compared both qualitatively and quantitatively to the experimental results, and the improved accuracy of the coupled tool compared with a standalone BES is underlined.

The generation of new neurons in the cerebral cortex requires that progenitor cells leave the cell cycle and activate specific programs of differentiation and migration. Genetic studies have identified some of the molecules controlling these cellular events, but how the different aspects of neurogenesis are integrated into a coherent developmental program remains unclear. One possible mechanism implicates multifunctional proteins that regulate, both cell cycle exit and cell differentiation.(1) A prime example is the cyclin-dependent kinase inhibitor p27(Kip1), which has recently been shown to function beyond cell cycle regulation and promote both neuronal differentiation and migration of newborn cortical neurons, through distinct and separable mechanisms. p27(Kip1) is therefore part of a machinery that couples the multiple events of neurogenesis in the cerebral cortex.
