This paper describes recent advances in prediction software using advanced data-mining tools, and shows how this can significantly increase the operational value of the data gathered. These new tools allow for new operational procedures to be defined that increase the usages of the network without decreasing security of supply. We will use the example of dynamic line rating, i.e. determining the thermal rating of an overhead line based on real-time environmental parameters (temperature, wind speed & direction and solar radiation) to highlight how the use of numerical data-mining tools can help us reliably predict future behavior of power networks.

Many nonlinear system identification methods have been introduced in the technical literature during the last thirty years. However, few of these methods were applied to real-life structures. In this context, the objective of the present paper is to demonstrate that the Restoring Force Surface (RFS) method can provide a reliable identification of a nonlinear spacecraft structure. The nonlinear component comprises an inertia wheel mounted on a support, the motion of which is constrained by eight elastomer plots and mechanical stops. Several adaptations to the RFS method are proposed, which include the elimination of kinematic constraints and the regularization of ill-conditioned inverse problems. The proposed methodology is demonstrated using numerical data. [less ▲]

The paper introduces an innovative complexity metric for passenger ships taking into account the shape complexity of steel parts, the assembly complexity and the material complexity. The goal is to provide the designer with such information throughout the design process so that an efficient design is obtained at the first design run. Real-time assessment of complexity and quality measurements is rather imperative to ensure efficient and effective optimality search, and to allow real-time adjustment of requirements during the design. Application and validation on a real passenger ship show that the new method is effective in giving a complementary aid to decision process for ship designers. [less ▲]

Dans le cadre du diagnostic du Schéma de Développement de l’Espace Régional (SDER, 2011) mené par la Conférence Permanente de Développement Territorial (CPDT), une analyse scientifique et prospective des enjeux territoriaux liés à la problématique de la biodiversité est proposée pour la Wallonie. Dans un premier temps, l’atteinte des objectifs spécifiques du SDER (1999) est examinée. Ensuite, partant des tendances d’évolution observées, les besoins adressés par la thématique « biodiversité » au territoire wallon sont définis, quantifiés et spatialisés. Ces propositions concrètes et scientifiquement argumentées sont destinées à alimenter la construction d’une stratégie globale de conservation de la nature en région wallonne. [less ▲]

The usual way of analyzing the challenges of territorial governance in a restructuring context lies on a planning vision of industrial strategies: once the announcement is operated, a series of events will occur following a sequential path. Few territorial studies refer to emergent restructuring processes or even to dramatic strategic reorientations. By comparing the evolving practices of two territorial actors, directly concerned with the strategic jolts of the restructuring process undertaken by the ArcelorMittal steel group, this paper scrutinizes the conditions under which one of them seems to answer this changing context with more efficacy than the other. The emphasis is put on what we propose to call a process of ‘adaptive institutionalization”, in which the actor in charge of territorial governance is able to cope with contextual variations while maintaining the stakeholders involved.

The host immune response is believed to tightly control viral replication of deltaretroviruses such as human T-lymphotropic virus type 1 (HTLV-1) and bovine leukemia virus (BLV). However, this assumption has not been definitely proven in vivo. In order to further evaluate the importance of immune response in the BLV model, we studied the fate of cells in which viral expression was transiently induced. Using a dual fluorochrome labeling approach, we show that ex vivo induction of viral expression induces higher death rates of B cells in vivo. Furthermore, cyclosporine treatment of these animals indicated that an efficient immune response is required to control virus expressing cells. [less ▲]

One major drawback of the post-combustion CO2 capture using conventional amine solvents is solvent degradation, which can be due to thermal as well as oxidative mechanisms. Degradation affects the CO2 capture process since it may cause corrosion, foaming and fouling, possibly inducing a decrease of the solvent efficiency and high additional operating costs due to solvent replacement. In order to study degradation of conventional amine solvents as well as degradation of novel solvents, a degradation test rig has been built at the University of Liège in collaboration with the company Laborelec, member of the GDF SUEZ group. Since degradation generally occurs within a few months in real plant conditions, this equipment has been designed to allow the study of different degradation mechanisms under accelerated conditions, at high temperatures (up to 140°C) and high partial pressures in oxygen and CO2 (total pressure up to 20 bar with varying gas composition). An advantage of this degradation test rig is that it can be used in batch as well as in semi-batch mode with constant gas flow. High gas-liquid contact efficiency is also ensured thanks to a mechanical agitation system combined with gas bubbling. For a typical run, 300g of aqueous amine solution (30 wt % MEA in water) is introduced into the reactor and degraded during two weeks. The degraded solutions are then analysed using high pressure liquid chromatography (HPLC) for MEA quantification and gas chromatography with flame ionization detector (GC-FID) for the characterization of degradation products. The gas phase is analysed by Fourier Transform Infra Red spectroscopy. The final objective of this work is to implement the data obtained from experimental results on the degradation test rig into an existing simulation model that has been developed based on an existing pilot plant.

Renal transplantation from living kidney donors is still relatively marginal in most of the European countries. However, this source of kidney grafts may help to overcome in part the organ donor shortage of cadaveric donors. The living donor strategy implies correct and objective information about donation risks and completely free acceptance of the living candidate of the donation. In this paper, we reviewed the consequences of kidney donation on the living donor health, considering very short term (linked to the surgery), short term (effect of nephrectomy on glomerular filtration rate) and long term (risk of mortality, chronic kidney disease, proteinuria and hypertension) consequences of kidney donation.

Proposant un retour sur l’idée assez répandue de travail sur Soi, les auteurs montrent combien celle-ci s’inscrit dans un profond mouvement de recomposition des politiques sociales et de régulation de société. Tout un ensemble de techniques, de procédures, d’interventions voient le jour pour mettre les usagers des dispositifs à l’épreuve d’eux-mêmes. Mais au-delà, sans doute se soucierait-on plus des modalités de gouvernement mêmes des populations que des populations elles-mêmes, comme si importait avant tout le problème de la gestion des dispositifs, de l’administration de la question sociale.

La prospective a souvent recours à la démarche participative. Fréquemment, dans son travail analytique, le prospectiviste fait intervenir les acteurs concernés par le système qu'il examine, que ceux-ci opèrent dans ce système ou qu’ils possèdent une expertise particulière par rapport à celui-ci. Dans la majorité des cas, cette intervention s’effectue au cours de l’exercice prospectif. Le présent working paper expose un autre type de situation : l’intervention et la participation des acteurs se placent ici en amont du travail prospectif, au moment de la délimitation des enjeux et des thématiques à considérer dans le cadre du développement d’un programme de recherche. L'expérience présentée par les auteurs, bien qu’elle recoure à l’utilisation d’un outil relativement classique en prospective, à savoir le Delphi, revêt un aspect original. Développée auprès de deux publics distincts, des équipes de recherche d’une part et des membres de l’administration wallonne, d’autre part, elle a permis d’identifier un certain nombre d’enjeux prospectifs majeurs pour la Wallonie et de définir des objets de recherche en rapport avec ces derniers. L'identification et la présentation de ces enjeux fait l’objet du présent texte. Dans un premier temps, celui-ci se propose de décrire le processus d’identification de ces enjeux et, dans un second temps, d’expliciter la nature de ceux-ci. [less ▲]
