TRIP-assisted steel has a complicated microstructure, obtained through well designed heat treatments and consisting of different phases, mainly ferrite, retained austenite, bainite and martensite. The drastic influence of microstructure on physical and mechanical properties makes metallographic examination a necessity for property understanding and enhancement. A fairly simple tint etching procedure (LePera method) using light microscopy and SEM observation ensures the distinction of ferrite, bainite and retained austenite/martensite grains. Nevertheless, the etching is not selective enough to allow a distinction between retained austenite and martensite. Atomic force microscopy was used for the phase identification and characterisation of this kind of steel. A series of tests was performed using AFM-contact mode and magnetic force microscopy in C-Mn-Si and C-Mn-Al TRIP-assisted steel after intercritical annealing followed by ageing, After ageing, some samples were tempered in order to make metallographic observation easier. It has been possible to identify the different phases and their topographic characteristics and to study their morphology using AFM. Orientation imaging microscopy was used to calibrate the observations done with AFM, distinguishing between bcc- and fcc-zones and quantify the retained austenite. [less ▲]

This paper deals with the evaluation of bounds on voltage and thermal security margins with respect to contingencies. A margin is the maximual pre-contingency power transfer between either a generation and a load area or two generation areas, such that the specified contingencies do not overload lines or make the system voltage unstable. The minimum and maximum margins are computed for given intervals of variations of bus injections. Each bound is the solution of a constrained L1-norm minimization (or maximization) problem, for which specific algorithms are given. Thermal overloads are handled through linearization, while for voltage stability, fast time simulation and instability mode analysis are used. Nonlinear situations of branch overloads are also considered. The method is illustrated on an 80-bus test system. [less ▲]

Aluminium-alloyed multiphase TRIP-assisted steels have been recently developed, so as to get rid of the disdavantages related to the high silicon contents classically used so far in TRIP-assisted steels. It has been shown that aluminium has a stronger ferritising effect than silicon and that it is slightly less efficient as far as austenite retention is concerned. A careful selection of the aluminium content and of the processing conditions is thus of primary importance in order to optimise the mechanical properties. The present study aims at determining the optimal heat treatment conditions leading to enhanced mechanical properties for two low aluminium-alloyed grades containing with mass contents of 0.12% C, 1.5% Mn and 0.5% Al or 1.0% Al, respectively. The microstructures generated during the heat treatment were assessed using SEM, X-ray diffraction and Mössbauer spectrometry. The mechanical properties were evaluated by uniaxial tensilte testing and the strain-hardening behaviour was characterised by means of an incremental strain-hardening exponent. The relations between the observed microstructures and the mechanical properties were discussed and, as a consequence, the importance of a careful control of the isothermal bainitic holding was highlighted.

This article is dealing with a quantitative comparison of different fast restoration approaches in the context of a Multi-Protocol Label Switching (MPLS) network. The objective is to analyse the general behaviour of these approaches (local rerouting, edge-to-edge rerouting, ...) in case of failure by means of simulations. This study is realised in the context of Best Effort only traffic, routing being done with a shortest paths algorithm. Many papers justify the choice between an edge-to-edge or a local scheme by means of intuition and then present a new algorithm for routing backup paths which try to optimize some parameters. Our approach aims to clarify the situation by comparing by means of concrete results the pros and cons of each mechanism. [less ▲]

The heterogeneous environment of multicast video streams naturally raises a network performance issue which can be addressed using a layered transmission scheme. A receiver is able to adapt the flow rate to its capacity by choosing an adequate subscription level among the different layers. A traditional static approach doesn't allow a full usage of the network capacity and should be combined with an adaptive transmission rate in each layer. We study the dynamic rate adaptation problem and develop a framework integrating a multirate adaptation algorithm and a transmission protocol for layered multicast video. Our main focus is the development of an adaptation algorithm offering rates matching the capacities of the receivers. We also want to set up a congestion control scheme and offer fairness towards TCP flows, while keeping a scalable framework. We evaluate and analyze the proposed architecture using simulations to point out its main characteristics. [less ▲]

An adult female harbour porpoise (Phocoena phocoena ) and a juvenile male harbour seal have been found dead on a Belgian beach in autumn 2001. The two bodies were in good condition (CC = 2). Pure and abundant growth of a small rod-shaped, Gram-labile bacterium was obtained aerobically and anaerobically on Columbia bloodagar from the heart blood, the mouth, the pharynx, the lungs, the intestine and the anus of the porpoise, and from the intestine, the pharynx, the mouth, the nose and the anus of the seal. The colonies were surrounded by a narrow zone of a-hemolysis. The catalase- and peroxydase-tests gave negative results. Rapid ID 32 Strepto (Biomérieux, France) sugar tests applied on porpoise’s heart blood, lungs and intestine, and on seal’s intestine and pharynx identified this isolate to Erysipelothrix rhusiopathiae. Erysipelothrix rhusiopathiae is not reported as a common cause of infection and death in wild cetaceans and wild pinnipeds in opposite to respectively captive dolphins and sea lions. Nevertheless, E. rhusiopathiae can be considered as the cause of death of the stranded harbour porpoise as it was present in heart blood and internal organs, and the seal was carrying the bacterium with lesions of enteritis which could be associated with E. rhusiopathiae infectio [less ▲]

La conclusion directe de l’utilisation de ce système d’enseignement a été une participation plus active des étudiants au cours mais également une responsabilisation de l’apprenant dans le processus de formation par la définition des performances cognitives. Les tests pratiqués durant l’année constituent une évaluation diagnostic pour l’enseignant qui a pu remédier dès le cours suivant aux problèmes de compréhension mis en évidence par le test. Les retombées indirectes comme les gains métacognitifs et l’acquisition d’autres compétences ne sont pas mesurables.

Business failure has been one of the most investigated topics in the finance and the strategic literature during the last seven decades. However, most of this literature has been heavily focused on business failure prediction (with a clear focus on short-term prediction) and, simultaneously, only a few studies have investigated business failure prevention, focusing on understanding how a company may fail through "failure paths" and on the identification of very early warning financial and non-financial signals and symptoms. This may be explained by a conceptual difficulty to exactly represent what business failure prevention may mean and by a practical difficulty to build a financial indicator really allowing to announce a bankruptcy at least three years or more in advance, giving then time to potential corporate recovery. With this paper, we then propose an investigation of this concept of "Business Failure Prevention" and we test on a sample of 6 250 Belgian SMEs the ability of a specific financial indicator (referred as "Economic Added Result" and based on the amount of accounting value added which remains within a company when it has paid for its internal and external production factors) to effectively predict a business failure at least three years before it happens.

Two new families of algorithms for computing openings of binary and label images are presented in this paper. The first family of algorithms is based on an horizontal scan, and a vertical scan that takes the result of the horizontal scan as input. With the results of these two scans it is possible to compute an opening with respect to a rectangle of any size. The second family of algorithms is based on the construction of an exhaustive list of rectangles included in an object. Rectangles of this list all have a maximal extension, i.e. no larger rectangle included in a region contains them. The opening then results from filling the output image with rectangles larger than the structuring element. After a description of the algorithms we provide a comparison of several algorithms in terms of computation time efficiency. The comparison shows that some of the new algorithms advantageously compete with existing algorithms. [less ▲]

The Constant Level Identification (CLI) method for nonlinear dynamical systems has been shown to identify accurately a wide variety of systems with discrete degrees of freedom. In this paper, the method is applied to a continuous nonlinear system, namely a simulated model of a vibrating beam attached to a nonlinear spring. A Rayleigh-Ritz series representation of the beam is assumed in order to extract the desired number of modal responses. Then, a combination of modal and physical coordinates are used in the identification process. It is shown that the CLI method can accurately capture the shape of the nonlinearity in the system.

Form@HETICE1 est un dispositif original de formation continuée des formateurs d’enseignants à un usage critique des Technologies de l’Information et de la Communication au sein des catégories pédagogiques des Hautes Ecoles (HE). Deux problématiques complémentaires guident la conception de ce dispositif : celle des usages éducatifs des TIC aux niveaux de la formation des futurs enseignants et des pratiques dans les écoles primaires et secondaires (Quels usages éducatifs des TIC?) (Denis, 2002) et celle plus globale de l’implantation d’une innovation qui tient compte du contexte organisationnel au sein duquel ce processus prend place : une rénovation d’ensemble des programmes de formation d’enseignants promue par le Ministère de la Communauté française (Quelle démarche d’intégration des TIC dans les pratiques de formation des enseignants ?). La prise en compte de ces deux problématiques a conduit une équipe de recherche collaborative à proposer des actions complémentaires qui dépassent la simple organisation de sessions de formation : • la mise en place d’un réseau de partage de ressources, • l'organisation de formations adaptées aux besoins des personnes ressources, • l'accompagnement de projets d'équipe dans chacune des Hautes Ecoles, • des actions parallèles concernant l’installation de « cybercentres » dans les établissements. Ces actions visent à produire un effet démultiplicateur : des personnes ressources participant au réseau forment leurs collègues, qui à leur tour forment les futurs enseignants amenés à introduire les TIC dans les activités menées avec leurs élèves.

Many information hiding techniques have recently been analyzed as they could help manage part of the digital rights. Among the general framework of information hiding, the focus has been put on steganography and on watermarking techniques. This paper proposes an entropy based technique for data embedding in images with a specific target, sometimes referred to as feature location: inclusion of a maximum amount of information instead of robustness against attacks. After an introduction, we analyze the error that results from a modification of the least significant bits. Then we describe our embedding technique. Finally we examine the upper bound of information that can be embedded in the least significant bits by means of our technique and we conclude. [less ▲]

Two approaches for the identification of multi-degree-of-freedom non-linear systems in the frequency domain have recently been introduced, i.e., the conditioned reverse path (CRP) method and the non-linear identification through feedback of the outputs (NIFO) method. The key idea of these methods is to eliminate the distortions caused by the presence of non-linearities in frequency response functions. In this paper, the theoretical background of the CRP and NIFO methods is briefly recalled. Then, the ability of these techniques to identify the behaviour of an experimental cantilever beam with a local geometrical non-linearity is tested. The results obtained with both methods are compared and discussed. [less ▲]

In a second step, we describe the structure of various controllers and identify the parameters to be optimized. Next, we present an optimization approach to find the controller parameters which optimize an overall performance objective. Results are presented on the Hydro-Québec system, in which load shedding is presently planned. [less ▲]

Une autre version de la composition est conservée à Bruxelles, au Musée Van Buuren. Injustement éclipsée par celle des Musées royaux des Beaux-Arts de Belgique, elle mérite d’être reconsidérée, même si elle n’est pas non plus due au pinceau de Bruegel. Peinte sur panneau, elle a été datée de la fin du XVIe siècle par dendrochronologie. [less ▲]

The City promotion project aims at arousing the awareness and possible use of the Very High Resolution (VHR) satellite images in the public agencies and education sector. This project is presently financed by the Belgian federal Office for Scientific, Technical and Cultural affairs (OSTC). Il this purpose, a poster has been prepared showing the three main towns in Belgium _ Brussels, Ghent and Liège - and a website has been devoted to the project. The core of the cities is represented by satellite maps at 1: 5 000 scale. Ikonos panchromatic and multispectral images are merged together in order to obtain coloured images at 1 m resolution able to render the urban fabric of these old cities. Moreover small excerpts at enlarged scale (1: 3 000) show typical places and building in panchromatic mode. The excerpt selected on the famous Brussels “Grand Place” is used to illustrate the fusion process between the panchromatic (1 m) and the multispectral (4 m) images. Two small scale insets present the regional context of these three towns thanks to a natural colour composite made of Landsat 7 ETM+ images on the one hand, and a classical physical map on the other hand. Various exploitations in the classroom of this poster, and others of the same kind, are suggested on the related website (http://www.geo.ulg.ac.be/eduweb). [less ▲]

Introduction: Sporadic pinealomas are intracranial tumors which incidence account for less than 1/107. This is the second report of secretory familial pinealoma in a mother and sister. We report for the first time neuroendocrine and preliminary genetic studies in these benign tumors. Methods and patients: Radioimmunoassay of urinary 6-sulphatoxymelatonin (a-MT6s) was performed in patients and in 90 control subjects aged 19-67 years. Samples were collected at 19-23 , 23-07 and 07-11 h. Endocrine studies including PRL, TSH, LH, FSH, ACTH, IGF1 and tumoral markers (bHCG, NSE, CEA) levels were measured. Lymphocytes caryotype was determined by CGH. Pituitary and pineal MRI were done in both patients. Results: The daughter was the index case. Diagnosis was done because of headaches. Pineal MRI showed a 17 x 14x 25 mm cystic lesion with gadolinium enhancement and no ventricular dilatation. Circadian rhythm of urinary a-MT6s was present but a-MT6s levels were clearly elevated compared to age-matched controls: 1455 ng/h at 19-23hs (308  261), 6012 ng/h at 23-07hs (1423753) and 3280 ng/h at 07-11hs (579340). The 55 years-old mother reported similar complaints during the daughter's follow-up. A pineal MRI identified a 18 x 20 x 14 mm cystic lesion. There were no signs of intracranial hypertension. None of the women reported sleep disturbances. Circadian rhythm of urinary a-MT6s was lost but a-MT6S levels were clearly elevated : 2380 ng/h at 19-23hs (173  153), 2812 ng/h at 23-07hs (768486) and 1897 ng/h at 07-11hs (480383). Endocrine studies and tumoral markers were in the normal range. No chromosomal abnormalities were found in both women (46,XX). Discussion: Due to the rare occurrence of sporadic pinealomas it is unlikely that such a tumor afflict two members in the same family. Although no histological proof was obtained in our patients, radiological findings and tumoral hypersecretion of melatonin derivated a-MT6s clearly suggest the pineal origin of these tumors. We suggest an autosomal dominant form of transmission with incomplete dominance as the most probable model of inheritance of familial pinealoma. [less ▲]

We present predictions on the total cross sections and on the ratio of the real part to the imaginary part of the elastic amplitude (rho parameter) for present and future pp and pbar p colliders, and on total cross sections for gamma p -> hadrons at cosmic-ray energies and for gamma gamma -> hadrons up to sqrt(s)=1 TeV. These predictions are based on a study of many possible analytic parametrisations and invoke the current hadronic dataset at t=0. The uncertainties on total cross sections, including the systematic theoretical errors, reach 1% at RHIC, 3% at the Tevatron, and 10% at the LHC, whereas those on the rho parameter are respectively 10%, 17%, and 26%.

Reinforcement learning consists of a collection of methods for approximating solutions to deterministic and stochastic optimal control problems of unknown dynamics. These methods learn by experience how to adjust a closed-loop control rule which is a mapping from the system states to control actions. This paper proposes an application of reinforcement learning methods to the control of a FACTS device aimed to damp power system oscillations. A detailed case study is carried out on a synthetic four-machine power system. [less ▲]

High-velocity plunging water jets, appearing at the downstream end of dam weirs and spillways, can create scour of the rock. The prediction of this scour is necessary to ensure the safety of the toe of the dam as well as the stability of its abutments. A physically based engineering model has been developed at the Laboratory of Hydraulic Constructions for evaluation of the ultimate scour depth. This model is based on experimental measurements of water pressures at plunge pool bottoms and inside underlying rock joints. The pressures inside the joints revealed to be of highly transient nature and governed by the presence of free air. Hence, a numerical modelling of these pressures was performed, in collaboration with the Laboratory of Applied Hydrodynamics and Hydraulic Constructions (HACH), based on the one-dimensional transient flow equations applied to a pseudo-fluid. The amount of free air is a function of the instantaneous pressure inside the joint and has been accounted for by means of appropriate celerity-pressure relationships. These relationships are defined by the ideal gas law and Henry’s law and were optimised by means of a genetic algorithm optimisation technique. Very good agreement has been obtained between the measured and computed pressures at the end location of one-dimensional closed-end rock joints. [less ▲]

Classical beam elements are based on the assumption that the cross section of the element re-mains unchanged during the entire loading. However, this can be too simple for modeling the behavior of thin-walled steel profiles, where local and distortional buckling are likely to occur. In this perspective, a spe-cial element taking into account the deformation of the cross section is presented and some examples of com-putations of critical bifurcation loads are presented. [less ▲]

The purpose of the present study was to re-explore the effects of age on memory for temporal context, assessed by a list discrimination task. Contrary to previous studies, each list (with faces as stimuli) was associated with a different type of judgement (honesty versus intelligence rating). The results showed no age differences on this task when no particular retrieval strategy was induced. However, when participants were encouraged to retrieve the list of occurrence of the items by retrieving the type of judgement made at encoding, there was an age effect. Older adults’ performance was at chance, whereas younger adults had a good performance. Moreover, younger adults who reported using the strategy performed as well as younger adults who did not use it. These results will be discussed by reference to the distinction between automatic versus effortful encoding processes. [less ▲]

This paper presents an original preparation method of metal catalysts supported on carbon porous material [1]. Carbon porous materials can be synthesised by evaporative drying and pyrolysis of aqueous resorcinol-formaldehyde gels whose operating, variables are correctly chosen. The porous texture of these materials is mainly controlled by the precursor solution pH. Texture analysis shows that it is possible to tailor the morphology of these materials : indeed, micro-macroporous, micro-mesoporous, microporous or non porous materials can be obtained by varying the pH value in a narrow pH interval. This texture control is slightly influenced by the introduction of a metal in the gel : the limits of the pH interval can slightly differ when a metal salt is added to the resorcinol-formaldehyde aqueous solution. Carbon supported nickel and palladium catalysts prepared by this method have proven to be active for ethylene hydrogenation. [less ▲]

The fine structure of the hydrophysical and hydrochemical parameters observed in the northeastern Black Sea during the 1999-2002 RV ”Akvanavt” cruises is discussed. The observed increase of organic phosphorus and urea at the boundary of oxic and anoxic waters testify that the hydrochmical structure is significantly influenced by chemosynthesis. The calculated nitrogen compound fluxes support the idea that organic nitrogen can be the significant part of total nitrogen in the oxic/anoxic interface. [less ▲]

The finite element code LAGAMINE developed since 1982 has been adapted to numerous finite elements and constitutive laws. The present researches on micro-macro modelling increase the requirement of CPU time. The parallelization of software is often divided into two main approaches: the coarse grain approach and the fine grain approach. For Finite Element software, the coarse grain method is usually characterized by the use of the mesh partitioning. In the fine grain approach, there is no partition of the mesh. The parallel program is made by the parallelization of instructions issued of the nalysis of dependences between the instructions, and the loops. The efficiency of all these approaches depends on the organization of the memory and on the used exchange protocol (MPI, PVM, or OpenMP). Our approach is intermediate between these two main categories of parallelization. It is characterized by the parallelization of the assembly of the stiffness matrix using a coarse grain approach and the use of a parallel direct solver. Because of the architecture of the available parallel computers, which are shared memory, we decided to use OpenMP protocol. [less ▲]
