A partir de l’examen des différents Plans de Cohésion Sociale (PCS) qui ont vu le jour sous l’impulsion des politiques européennes et ce, dans un contexte de crise de modèle des Etats sociaux européens, cet exposé proposera une approche critique des tentatives actuelles de recomposition des politiques sociales. Ce mouvement puise largement son inspiration dans un projet de participation de tous au sein de la société. Il s’agit désormais d’animer, de faire participer, d’inciter, de produire de l’intégration là où autrefois l’action publique visait prioritairement à protéger, à conférer un statut et une position sociale. Une nouvelle intention publique aurait fait son apparition dans le champ des politiques sociales. Elle viserait davantage à solliciter les individus, à faire appel à leur subjectivité tout en multipliant les lieux d’écoute. Toutefois, pour devenir globalement plus individualisées et subjectives, les politiques sociales ont dû puiser là où précisément des politiques de la subjectivité étaient éprouvées de longue date, à savoir dans les schémas assistanciels de l’aide sociale. On assisterait ainsi à une reconfiguration des frontières du social. Saisi de nouvelles attentes plus singulières et particularistes, il puiserait de plus en plus largement son inspiration aux sources du travail social, se « travaillerait », se mettrait en action par l’intermédiaire d’intervenants rompus aux techniques relationnelles et aux conduites d’entretien [less ▲]

Wythoff's game is a century old classical two players combinatorial game. When studying this game, Beatty sequences associated with the Golden Ratio, syntactical properties of the representations of integers in the Fibonacci or Zeckendorf numeration system and the morphic Fibonacci word appear naturally in characterizations of its P-positions. Recall that whatever is the move played from a P-position, the other player has a winning strategy. Contrarily to the usual approach where one defines a new game by a set of rules and then tries to characterize the corresponding set of P-positions, our motivations are to proceed the other way around: keep the original set of P-positons while changing the rules. We consider extensions and restrictions of Wythoff's game having exactly the same set of P-positions as the original game. Our results are the following one: no strict subset of rules gives the same set of P-positions. On the other hand, we characterize all moves that can be adjoined while preserving the original set of P-positions. Testing if a move belongs to such an extended set of rules is shown to be done in polynomial time. In this talk, we won't consider many game theoretical aspects (but we will recall some basic facts on combinatorial games). We focus mainly on the role played by numeration systems, regular languages and bidimensional words generated by substitutions/morphisms. Indeed, games like this one provide nice interaction between combinatorics on words and combinatorial game theory. For instance, the set of P-positions of Wythoff's game are "coded" by the infinite Fibonacci word. Therefore, many arguments rely on this word, on automatic sequences and on the corresponding numeration systems. With these tools, we provide new bidimensional (shape-symmetric in the sense of Arnaud Maes) morphisms generating an infinite picture encoding respectively P-positions of Wythoff's game and moves that can be adjoined preserving the same set of P-positions.

This work takes place in the context of the following PhD research topic. Alluvial plains constitute essential geological bodies for environmental studies such contaminated sites remediation, low-enthalpy geothermal energy or groundwater resources. The general objective of this work is to contribute to a better quantification of the heterogeneity of the parameters governing flow and transport processes by combining near-surface geophysics and geostatistics. Two-points geostatistical approaches (variogram based) have been developed to quantify the heterogeneity of one geological formation but fail to reproduce the heterogeneity of fluvial deposits with multiple facies. Multiple-points geostatistics introduced the training image concept to replace the variogram within an extended sequential simulation framework. The role of the training image is to depict the conceptual geological patterns. Previous studies have demonstrated the need for more conditioning data to generate an efficient training image. The use of geophysics in this context has been studied in the petroleum research with wave-based methods (seismic reflection data). However, little research has been done to assess the use of near-surface geophysical measurements, relying on potential and wave methods, to condition multiple-point geostatistics for environmental studies. This research project will focus on three specific objectives. The first will consist in computing conceptual training images from the combination of near-surface geophysics images, geological information and borehole data. The second objective will use these images to build models of the subsurface properties with multiple-point geostatistics conditioned to site-specific near-surface geophysical data and borehole information. Finally, groundwater model parameter estimation will be performed using a geologically consistent perturbation approach based on tracer experiments, using well sampling and time-lapse geophysical data. The approach will be demonstrated on both synthetic benchmarks and real field sites. This presentation shows preliminary research results on the use of combined geophysical techniques to improve geophysical models, the building of geological scenarios (training images) in the Meuse alluvial aquifer and the use of time-lapse ERT data to improve our understanding of hydrogeological reservoirs.

Qu’est-ce que la restauration d’une œuvre d’art ? La question est plus délicate qu’il n’y paraît, car elle met en jeu le sens que l’on donne à l’œuvre d’art et la conception que l’on a de son authenticité. Elle a suscité des réflexions passionnantes, notamment sous la plume de Cesare Brandi et de Paul Philippot. Ceux-ci ont jeté les bases d’une véritable théorie de la restauration de l’œuvre d’art, tenant compte de toute la complexité de celle-ci, la reconnaissant comme entité conceptuelle et matérielle à la fois, dotée d’une double dimension esthétique et historique. Sans négliger ce substrat de réflexions très riches, les praticiens de la restauration prennent volontiers appui sur un cadre pragmatique élaboré par le Committee for Conservation de l’International Council of Museums (ICOM-CC), distinguant conservation préventive, conservation curative et restauration proprement dite. La restauration y est définie comme l’ensemble des actions accomplies sur un bien culturel en état stable, afin d’en améliorer l’appréciation, la compréhension et l’usage. Il est précisé que ces actions sont entreprises quand le bien a perdu une part de sa signification ou de sa fonction, du fait de détériorations ou de remaniements passés. Ces actions modifient généralement l’apparence du bien. Une telle définition, simple à première vue, soulève en fait de nombreuses questions, que je proposerai d’examiner sur la base d’un exemple bien connu de tous : celui des restaurations accomplies sur les fresques de Michel-Ange à la chapelle Sixtine entre 1980 et 1994. Je retracerai brièvement les étapes de ces grandes campagnes de restaurations que d’aucuns considèrent comme les plus importantes du XXe siècle. Je montrerai que, selon les normes les plus exigeantes actuellement encore en vigueur, elles illustraient un niveau d’excellence extrême. En effet, elles se fondaient sur des études préalables menées par des équipes multidisciplinaires, qui en assurèrent ensuite le suivi pas à pas ; elles furent accomplies par des praticiens hautement qualifiés ; elles furent scrupuleusement documentées dans toutes leurs étapes, et enfin, elles donnèrent lieu à rapports circonstanciés, qui furent intégralement publiés. Elles suscitèrent pourtant de vives critiques, du moins au départ, lorsqu’on en dévoila les premiers résultats. Il fallut s’habituer à l’éclat des couleurs des fresques mises à nu, débarrassées de la patine que le temps leur avait conférée. Il fallut apprendre à composer avec un « nouveau Michel-Ange », très différent du chantre des ténèbres que l’on admirait jusque là. Toute la vision de l’évolution de la peinture toscane des XVe et XVIe siècles s’en trouva bouleversée. Nous sommes donc ici confrontés à un cas d’école pour mesurer combien notre appréciation des œuvres est tributaire des fluctuations de leur état matériel. Le restaurateur d’art effectue une démarche qui n’est pas loin d’évoquer celle qu’accomplissent les philologues éditant un texte. Selon les termes mêmes de Gianluigi Colalucci, restaurateur en chef des fresques de Michel-Ange à la Sixtine, il s’agissait pour lui de « récupérer le texte pictural originel de manière à en rendre possible une lecture philologique correcte ». En réalité, qu’il en ait ou non conscience, le restaurateur d’art, comme le philologue, se livre toujours à une interprétation. Celle-ci est historiquement conditionnée, et elle n’est pas exempte de subjectivité. La responsabilité du restaurateur d’art est sans doute encore plus lourde que celle du philologue, puisqu’il agit, quant à lui, directement, physiquement, sur un unicum, qu’il transforme durablement. Même lorsqu’elle est accomplie avec grand soin, après mûre réflexion, par des professionnels travaillant de concert avec les meilleurs experts, la restauration d’une peinture ne récupère jamais le « texte pictural originel ». Elle remplace un ancien filtre de lecture par un autre, jugé plus adéquat, au travers duquel elle impose de regarder désormais cette œuvre. Ce faisant, elle entretient avec l’histoire de l’art des liens profonds et inextricables. Si elle l’interroge et s’appuie sur elle, elle l’informe en retour, lui procure des données nouvelles, conduisant parfois à l’ébranler, lui imposant parfois de se reconfigurer, favorisant ainsi ses progrès. Sans conteste, elle mérite d’occuper une place de choix dans la Kunstwissenschaft. [less ▲]

Multiplication, both in number and variety of databases in recent decades is a potential bottleneck in the process of decision making. Therefore, data warehouses and OLAP (Online Analytical Processing) were born respectively to archive and analyse these data at different levels of aggregation.

This presentation will discuss the various tools (particularly open source tools) and approaches in this new domain of geomatics. [less ▲]

The European Space Agency ESA aspires the exploration of the universe using space-borne infrared telescopes with large aperture operating at cryogenic temperature. The Herschel space telescope is currently returning its first scientific observations orbiting from the Lagrange point L2 and the foreseen infrared observatory Spica is currently under study. The large diameter of the primary mirrors and the operation at cryogenic temperature require the use of ultra stable materials and wellcharacterised dimensional change of the structure as function of temperature. Dimensional stability and high precision data on the thermal expansion is also relevant for the cryogenic spectographs MIRI and NIRspec on the James Webb Space Telescope JWST, for high-precision laser interferometer LISA and for spacecraft sent to a hot environment such as BepiColombo and Solar Orbiter. Although European industry has proven effective at designing and building thermally stable structures, problems have been encountered in measuring the absolute CTE of stable materials. In one recent mission, the design CTE had to be changed 6 times over a 2 year period and when the telescope was tested in cryogenic conditions, an error was found in the back focal plane of over a centimetre. It is an objective of ESA to determine the CTE of stable materials continuously as function of temperature with an uncertainty of 3 ppb/K down to a temperature of 5 K. [less ▲]

Les recherches présentées ici portent sur la prédiction de la sédimentation dans des bassins rectangulaires peu profonds. Ceux-ci sont fréquemment utilisés en hydraulique urbaine et constituent une idéalisation pertinente de multiples configurations plus complexes. Des campagnes expérimentales complémentaires ont été menées de concert à l’Université de Liège ainsi que dans d’autres laboratoires européens. Ces modélisations physiques, réalisées sur fond fixe et mobile, ont été complétées par des simulations numériques tant hydrodynamiques qu’hydrosédimentaires. Les analyses ont d’emblée révélé la complexité des écoulements dans de tels bassins, qui présentent des recirculations asymétriques malgré la symétrie hydraulique et géométrique du dispositif. La typologie des écoulements est caractérisée par plusieurs transitions, de type « bifurcations », entre écoulement symétrique et écoulement dévié. Ce faisant, nous avons abouti à une unification des critères de prédiction du type d’écoulement pour des nombres de Reynolds élevés, la formulation proposée s’appliquant à l’ensemble des résultats expérimentaux connus dans la littérature. L’étude des dépôts et du taux de rétention des sédiments dans les bassins a démontré la corrélation forte entre ces paramètres et la configuration de l’écoulement, ce qui confirme a posteriori l’importance de critères prédictifs du type d’écoulement. Ces recherches ont finalement permis d’identifier des recommandations pratiques, destinées soit à éviter les instabilités d’écoulement lors du design de bassins ou, a contrario, à exploiter pleinement ces instabilités afin de maximiser l’efficacité du bassin (stockage ou décantation).

The measurement of the Rossiter-MacLaughlin effect in transiting planetary systems has revealed a significant population of hot giant planets orbiting outside the equatorial plane of their parent star. In an attempt to improve our understanding of these spin-orbit misalignements, and discriminate between various scenarios, we propose to determine whether debris disks are located within the equatorial plane of their star using infrared spectro-interferometry. To validate our approch, we have chosen the bright star Fomalhaut and measured the orientation of its rotationnally-distorted stellar photosphere using micro-arcsecond precision VLTI/AMBER spectro-astrometry within the Br-gamma line. The derived poition angle is in perfect agreement with the position angle of the cold debris disk imaged in the visible and sub-millimeter domains. We discuss the implications of this result on our understanding of the dust grain properties in the Fomalhaut disk, and how this study can be extended to other debris disk systems. [less ▲]

The TCLUST procedure is a new robust clustering method introduced by García-Escudero et al. (2008). It performs clustering with the aim of finding clusters with different scatters and weights. As the corresponding objective function can be unbounded, a restriction is added on the eigenvalues-ratio of the scatter matrices. The robustness of the method is guaranteed by allowing the trimming of a given proportion of observations. This trimming level has to be chosen by the practitioner, as well as the number of clusters. Suitable values for these parameters can be obtained throughout the careful examination of some classification trimmed likelihood curves (García-Escudero et al., 2010). The first part of this talk will consist of a brief presentation of this clustering procedure and the related R package (tclust). In the second part of the talk, the robustness of the TCLUST procedure, and more precisely its breakdown behavior, will be studied. We will see that the estimator of the scatter matrices can resist to more outliers than the number of trimmed observations. However, the brekdown point of estimator of the centers is very poor. Two observations are sufficient to make the centers break down. This is due to the stringency of the classical breakdown point; the estimator has to have a good behavior even on samples which can hardly be clustered. For this reason, Gallegos and Ritter (2005) introduced the restricted breakdown point. The idea is to restrict the analysis to the class of “well-separated” data sets. On this class, the estimator of the centers has a breakdown point of α, the level of trimming. [less ▲]

The current project aims to develop a generic set of analysis methods to quantify anthropogenic degradation of tropical ecosystems. This will assist in landscape planning for ecosystem restoration and sustainable management of human impacts. Indeed, the analysis methods will enable to detect landscape degradation and its anthropogenic drivers based on their spatial properties, less complex or expensive to obtain than in-situ data. The project consists of two parts: - methodological research and development, based on principles landscape ecology and combined with other disciplines like remote sensing, geographic information systems, sociology and agronomy (in progress), - application of the developed pattern metrics on new study cases for evaluation and validation. Using study cases in tropical areas, the development of a typology enables to identify, classify and analyze degradation origin, its spatial properties and the ecosystems involved. The following pressures: woodcut for charcoal production, agricultural extension, mining activity and climate change have already been tested for the following natural ecosystems: rainforest, woodland, savannah. Afterwards, different metrics will be evaluated statistically with regard to their potential to capture anthropogenic effects. The Simpson diversity index, Largest Patch Index, fractal dimension and O'Neill disturbance index have already been tested and sometimes adapted. Critical thresholds will be defined in order to detect critical degradation levels of the terrestrial ecosystems. The best metrics will be calculated for new case(s) of anthropogenic impacts on landscapes (Cambodia?) in order to validate the correlation between metric outcomes and in situ observations. [less ▲]

La différence entre les méthodes de classi cation et les méthodes de cluster- ing réside dans le fait que, en clustering, on ne dispose pas d'un échantillon de travail pour lequel l'appartenance à l'un des groupes est connue. Néanmoins, même lorsque l'on dispose de cette information, il est toujours possible d'appliquer une méthode de clustering aux données en oubliant les appartenances. On pour- rait alors s'attendre à une perte d'efficacité. Lors de ce séminaire, nous allons voir qu'en appliquant la méthode 2-means, il est possible de gagner de l'efficacité par rapport à certaines méthodes de classiffication lorsque la répartition des ob- servations est symétrique. A coté de cela, nous étudierons l'impact que l'introduction de contamina- tion dans les observations peut avoir sur la procèdure 2-means. Pour cela, nous utiliserons deux outils bien connus en statistique robuste : la fonction d'influence qui mesure l'impact d'une contamination infinitésimale en un point et le point de rupture qui mesure la quantité de contamination nécessaire pour déstabiliser complétement un estimateur. Nous verrons également d'autres procèdure de clustering plus résistante à la contamination, comme la méthode 2-means généralisée et la procèdure TCLUST. [less ▲]

La spectroscopie Raman est une technique particulièrement bien adaptée à l'analyse des oeuvres d'art et des pièces archéologiques. Cette présentation illustre, sans être exhaustive, plusieurs domaines d'application comme l'étude des pigments, des molécules organiques, des produits de corrosion et des minéraux et gemmes. Elle se focalise ensuite sur deux exemples détaillées concernant l'étude des peintures murales de la Cathédrale de Tournai et celle des restes colorés d'un insigne d'épaule retrouvé sur la dépouille d'un soldat australien de la première guerre mondiale.

Cette communication avait pour objectif de baliser l'atelier "langues modernes" organisé dans le cadre de l'Université d'été du Cifen 2011. Après avoir défini quelques termes-clés comme "compétences" et "approche par compétences", G. Simons a introduit la notion de risques d'inéquité liés à l'adoption de l'approche par compétences en langues. Enfin, quelques pistes de solutions ont été proposées aux niveaux macro, meso et micro pour tenter de réduire ces risques d'inéquité. [less ▲]

R is an open-source statistical software and of increasing interest for the scientific community. It can be installed on all usual platforms (Windows, Linux, Mac) and is suitable for many statistical analyzes, graphical representation, intensive computation and programming, among others. New functionalities and packages are developed regularly and the R web community ensures a constant development and increasing usefulness of R, not only for pure statisticians but also for practitioners from various fields (psychology, education, biometrics, econometrics, etc.). Its main drawback, however, is that it requires preliminary training and practice to handle the various aspects of the software and to become efficient in using R. The purpose of this workshop is to present the basic aspects of R, from the installation to the basic statistical analysis. The following themes will be developed: installation, importing data, R objects and structures, basic computations, graphics, packages and libraries, programming in R, basic statistical modeling and testing. The workshop will be practice-oriented, with sessions mixing both “theoretical” presentations and practical applications. Live demonstrations of R will also be performed. Participants are invited to bring their laptop and to take part to the practical exercises. Slides, R scripts and illustrative data sets will be provided. [less ▲]

The project has three main objectives. The first objective is to design a method of construction wood that can be industrialized, so that the elements are then assembled on site. In this way, the manufacturing costs should be reduced. The second objective is to design a low energy house, whose consumption is less than an equivalent of 6 litres of oil per square meter per year (or 60 kWh/m²yr). The third objective is to employ less qualified workers in workshops or on site. Because the construction industry suffers from a shortage of workers, despite a high unemployment rate in our region.

In Belgium, like in many European countries, the existing buildings represent the main part of the building stock. These buildings are relatively old, and most of the dwellings are not at all or not well thermally insulated; their airtightness is weak and their heating installations are old. We can find there real potential improvement and high possibilities of renovation. The owner, the contractor and the architect are confronted with many renovation options, and choosing the best intervention scenarios is never easy. It’s in this context that the software REFLEX (for Rénovation EFficace d’un Logement EXistant, in English: efficient renovation of an existing dwelling) has been developed. [less ▲]
