We revisit the limit on very light axion-like particles (ALPs) from the absence of gamma rays coincidental with the neutrino burst from SN1987A. We use updated supernova simulations, modern models for the magnetic field inside the Galaxy, and a Primakoff cross section which takes into account proton-degeneracy and mass-reduction effects. We finally give an updated exclusion plot for the electromagnetic coupling of sub-eV ALPs, comparing our new bound with other limits as well as with future ALP searches. [less ▲]

Syntactic analyses describe grouping operations that explain how words are combined to form utterances. The nature of these operations depends on the approach. In a constituency-based approach, grouping operations are ordered, or stratified, part-whole relations. In a dependency-based approach, grouping operations identify a governor (or head), i.e. they are directed hierarchical relations between words. It is possible to convert a constituency tree into a dependency tree by dereifying the nodes, by identifying the governor and by removing the stratification of the part-whole relations. Polygraphs combine the two types of information into a single structure and are therefore a more powerful formalism. By relaxing constraints, polygraphs also allow to underspecify both kinds of information. [less ▲]

Chacun sait que chez les anciens Grecs, Crésus passait pour un roi richissime à la tête d’un des plus puissants royaumes de son temps. En apportaient la preuve ses nombreuses offrandes consacrées au sanctuaire de Delphes, visibles de tous. L’épisode de sa mort sur un bûcher, un des moments les plus dramatiques de son existence, fut évoqué par nombre d’auteurs anciens et elle a fait l’objet de représentations figurées tout au long de l’Antiquité. Enfin, il ne faut pas oublier que pour un Grec du VIe siècle, l’homme passait pour constituer comme un rempart infranchissable protégeant les cités grecques de la côte d’Asie Mineure contre la puissance montante des Perses de Cyrus II le Grand. Ainsi la défaite inattendue du roi lydien face aux troupes perses en Ptérie constitue-t-elle un épisode décisif de l’époque archaïque grecque dans la mesure où elle signe la fin prochaine du royaume lydien et de son formidable maître. Les cités grecques d’Asie Mineure allaient vite devoir face à leur destin : une soumission aux Perses puis leur révolte entraînant les terribles guerres médiques. Dans notre exposé, on mettra l’accent sur les causes de cette bataille décisive perdue par Crésus à Ptérie, sur son déroulement et ses enjeux à la lumière des sources à notre disposition. On sera amené à analyser le tracé de la Route royale empruntée par le dernier descendant de Gygès pour se rendre en Cappadoce ; on aura ainsi l’occasion de voir que son existence est bien antérieure à l’arrivée des Perses en Anatolie occidentale. Enfin notre exposé présentera la localisation exacte de la ville de Ptérie, une question débattue depuis longtemps mais que des fouilles archéologiques récentes ont permis d’éclairer. [less ▲]

This paper scrutinizes various dependency-based representations of the syntax of function words, such as prepositions. The focus is on the underlying formal object used to encode the linguistic analyses and its relation to the corresponding linguistic theory. Two types of representation are proposed for the encoding of syntactic properties and applied for function words. Although the mathematical object introduced here encodes a dependency-based analysis, it does not consist in a tree. It is rather more general than a graph (it allows edges to be vertices of other edges) and is called a polygraph. [less ▲]

La crise généralisée qui, depuis quelques années, a affaibli les économies de nombre d’états, a eu des conséquences sur la typologie des migrations internationales : les trajectoires, les projets, les destinations, les départs se sont modifiés en fonction de nouveaux facteurs auxquels les individus et les groupes étaient confrontés . A côté de ces macro-dynamiques globales, la crise a également engendré des changements dans la vie quotidienne des migrants lorsqu’ils étaient déjà partis et qu’ils s’étaient déjà installés ailleurs. Dans ce cadre, ma contribution vise à analyser les pratiques d’approvisionnement alimentaire d’un groupe de migrantes marocaines en Italie mettant en place des stratégies pour faire face aux conséquences concrètes de la crise économique (notamment la diminution de leur pouvoir d’achat en conséquence de leur précarité professionnelle). Au travers de plusieurs déplacements dans la ville où elles habitaient et de la mobilisation des réseaux familiaux alimentant des circuits informels d’échange de biens, ces femmes satisfaisaient leurs différentes exigences – parmi lesquelles le désir de performer des préparations propres à leur mémoire incorporée – tout en répondant aux contraintes économiques déterminées par la crise. Je vais ainsi démontrer qu’en dépit des difficultés rencontrées, ces femmes arrivaient à exercer une agency dans le nouvel espace vécu et à se positionner de façon active au travers de leurs choix et conduites quotidiennes.

Renewable energy sources, because of their intermittence, could not afford a stable production and an adequate variability according to the energy demand. Underground Pumped Storage Hydroelectricity (UPSH) using abandoned mine works is an interesting alternative, in flat regions, to store energy during low demand periods by pumping water from an underground mine to an upper reservoir. From the hydrogeological point of view, two considerations can arise for studying the feasibility before constructing an UPSH plant: 1) the alteration of the natural conditions of surrounding aquifers, and (2) the efficiency of the plant depending on possible leakage in the cavities from the hydrogeological environment. A potential old slate mine was selected through a multi-criterion method and its geometrical and hydrogeological characteristics are used to build a simple but typical model. With the help of the HFEMC approach implemented in the code SUFT3D (HEG-ULg), the groundwater flows are modelled for a representative cavity. Simulations of groundwater flow induced by a UPSH system are performed and the main variables are identified. Piezometric heads around the reservoir oscillate, the magnitude of the oscillations and the time to achieve a pseudo-steady state (magnitude and head reached during oscillations not varying anymore with time) depend on the boundaries, the parameters of the aquifer and the characteristics of the underground reservoir. The required hydrogeological conditions are deduced and a screening methodology can be proposed to assess the main impacts caused in aquifers by UPSH plants. Their efficiency regarding the water level evolution inside the reservoir is also considered accommodating the cyclic pumped storage schemes. [less ▲]

Simultaneous solute and heat tracer test provides essential information for a reliable assessment of low temperature geothermal systems. The actual efficiency of ‘open systems’, including heat storage projects, is strongly affected by the heterogeneity of the hydraulic conductivity field (K-field). It could be also useful for assessing the cumulative impacts of numerous projects in urban areas on the groundwater resources. Using field data from a solute and heat tracer test conducted in the alluvial aquifer of the Meuse River (Belgium), an inverse problem of parameter estimation is solved. The tracing experiment consisted in simultaneously injecting heated water and a dye tracer in a piezometer and monitoring the evolution of groundwater temperature and tracer concentration in the recovery well and in monitoring wells. To get insights in the 3D characteristics of the heat plume, an arrangement of three transects of observation wells was used. The breakthrough curves measured in the recovery well showed that heat transfer in the alluvial aquifer is slower and more dispersive than solute transport. Recovery is very low for heat while in the same time it is measured as relatively high for the solute tracer. This is due to the fact that heat transport is a thermal diffusion dominated process. For conditions corresponding to high Peclet numbers, the hydraulic conductivity is the primary calibration parameter for predicting heat plume distribution. Heat diffusion is larger than molecular diffusion, implying that exchange between groundwater and the porous medium matrix is far more significant for heat than for solute tracers. [less ▲]

L’épicondylite latérale est plus communément appelée tennis elbow suite à sa fréquence élevée d’apparition chez les joueurs de tennis – lors du mouvement de revers, principalement. Cette pathologie du membre supérieur, fréquente chez les sportifs, touche particulièrement la région épicondylienne radiale, zone d’insertion commune des muscles extenseurs. L’épicondylite latérale est 7 à 20 fois plus répandue que l’épicondylite médiale souvent nommée golfer’s elbow. L’âge est un facteur de risque important, la prévalence est la plus élevée chez les individus âgés entre 35 et 55 ans. Un autre élément prédisposant est la répétition d’un mouvement pendant plus de 2 à 4 heures par jour. Certains sports ont une plus grande incidence sur l’épicondylite que d’autres. Le tennis, le windsurf, l’escalade, le lancer du javelot ou les sports en chaises roulantes sont des activités à haut risque concernant les tendinopathies du coude. Le milieu professionnel joue aussi son rôle délétère envers les muscles épicondyliens. Le travail à la chaine sur des machines, obligeant des mouvements de flexion-extension répétés du coude, de la main et des doigts, peut rapidement être responsable d’épicondylites. De même, la position de travail, le matériel inadapté, le port d’outils trop lourds, le cumul de gestes à risque et, globalement, la mauvaise ergonomie du poste de travail constituent des facteurs déclenchant des tendinopathies du coude. Les épicondylites peuvent être aussi provoquées par des gestes quotidiens : le ménage, le bricolage, la traction de « caddy » au supermarché, l’excès d’activité sur ordinateur par exemple. Malgré une importante diversité des traitements conservateurs – repos, glace, orthèse, anti-inflammatoire non-stéroïdien en phase aigüe, ultrasons, stimulation électrique, massage transverse profond, étirement et onde de chocs –, les symptômes persistent ou des rechutes après un retour à l’activité incriminée sont souvent observées. De nouvelles thérapeutiques, par injection de plasma riche en plaquettes ou acide hyaluronique par exemple, sont également développées pour traiter les tendinopathies rebelles. Au final, si le traitement conservateur n’est plus efficace, la chirurgie sera envisagée. [less ▲]

The frequency-domain nonlinear subspace identification (FNSI) method has recently been successfully applied to large-scale nonlinear structures. One of the key features of FNSI is the nonlinear generalisation of the stabilisation diagram. However, as in linear system identification, the selection of the model order in the diagram is complicated by the presence of spurious poles, resulting from noise and modelling errors. Spurious poles have been shown to strongly perturb the estimation of the nonlinear coefficients. The present paper establishes a constructive procedure to discriminate between spurious and genuine poles. This procedure is derived in modal space and is based on a dominancy index and on model reduction techniques. It is demonstrated on a complete satellite structure possessing nonsmooth nonlinearities and high modal density. Spurious frequency variations in the nonlinear coefficients are proved to be effectively removed, significantly improving the quality of the overall identified model. [less ▲]

In the present paper, the observation and characterization of isolated response curves (IRCs) are experimentally reported in the case of a nonlinear system consisting of two masses sliding on an horizontal guide. Transverse springs are attached to one mass to provide the nonlinear restoring force, and a harmonic motion of the complete system is imposed by prescribing the displacement of their supports. The existence of an IRC is related to a 3:1 internal resonance between the two modes of the system. The observed IRC is studied in detached and merged conditions using swept-sine excitations and system perturbations. [less ▲]

Experimental dynamic substructuring is a means whereby a mathematical model for a substructure can be obtained experimentally and then coupled to a model for the rest of the assembly to predict the response. Recently, various methods have been proposed that use a transmission simulator to overcome sensitivity to measurement errors and to exercise the interface between the substructures; including the Craig-Bampton, Dual Craig-Bampton, and Craig-Mayes methods. This work compares the advantages and disadvantages of these reduced order modeling strategies for two dynamic substructuring problems. The methods are first used on an analytical beam model to validate the methodologies. Then they are used to obtain an experimental model for structure consisting of a cylinder with several components inside connected to the outside case by foam with uncertain properties. This represents an exceedingly difficult structure to model and so experimental substructuring could be an attractive way to obtain a model of the system. [less ▲]

The objective of the paper is to obtain the frequency response curves of nonlinear mechanical systems from broadband testing. The proposed approach consists in coupling an identification method with a continuation method. Specifically, the frequency-domain nonlinear subspace identification (FNSI) method is first used to derive an experimental model of the structure in state space from broadband measurements. The harmonic balance method coupled with arclength continuation then utilizes this experimental model to compute the frequency response curves of the system. The method is demonstrated using a numerical example. [less ▲]

Most studies tackling hysteresis identification in the technical literature follow white-box approaches, i.e. they rely on the assumption that measured data obey a specific hysteretic model. Such an assumption may be a hard requirement to handle in real applications, since hysteresis is a highly individualistic nonlinear behaviour. The present paper adopts a black-box approach based on nonlinear state-space models to identify hysteresis dynamics. This approach is shown to provide a general framework to hysteresis identification, featuring flexibility and parsimony of representation. Nonlinear model terms are constructed as a multivariate polynomial in the state variables, and parameter estimation is performed by minimising weighted least-squares cost functions. Technical issues, including the selection of the model order and the polynomial degree, are discussed, and model validation is achieved in both broadband and sine conditions. The study is carried out numerically by exploiting synthetic data generated via the Bouc-Wen equations. [less ▲]

demander dans quelle mesure l’injonction du brigand qui exige « la bourse ou la vie ! » peut être comparée à la norme de comportement édictée par un Etat sous la forme d’une loi, c’est poser la sempiternelle question de la frontière qui sépare le droit du non-droit, tout au moins dans une perspective juspositiviste, en tant que cette école de théorie du droit refuse de définir le phénomène juridique en se référant à une valeur ou un ensemble de valeurs. La frontière du droit et du non-droit est en effet particulièrement difficile à tracer, nonobstant plusieurs siècles de discussions philosophiques à ce sujet. Lorsque, fatigué de parcourir les chemins, le brigand décide de s’installer en ville pour s’y adonner au racket des commerçants du quartier et qu’il s’adjoint ensuite le concours d’autres bandits, c’est un gang de malfaiteurs qui voit le jour. Si, ultérieurement, ce gang se concerte avec d’autres bandes de truands pour s’épauler mutuellement dans les exactions auxquelles ils se livrent sur leurs territoires respectifs, il prend alors la forme d’une organisation criminelle ou, au sens large du terme, d’une « mafia ». Le cinéma de Francis Ford Coppola, Martin Scorsese, Brian De Palma, Sergio Leone ou bien encore Matteo Garrone, entre autres, dépeint, souvent avec réalisme, la genèse et le fonctionnement de telles organisations criminelles. La communication a proposé, au moyen d’illustrations tirées des films de ces grands cinéastes, une analyse de microscopie juridique du crime organisé. Une description serrée de la particule élémentaire du phénomène juridique, identifiée par Lucien François dans son ouvrage de théorie du droit Le cap des Tempêtes sous l’appellation de « jurème », met en lumière une indéniable proximité entre les techniques de pouvoir utilisées respectivement par le brigand isolé, la bande organisée et l’Etat souverain. En remontant ensuite vers la structure plus complexe d’un système étatique, on se demandera si, en fin de compte, dans la vision juspositiviste poussée au bout de sa logique par Lucien François, l’Etat ne pourrait être réduit, d’un point de vue ontologique, à un pouvoir de fait comparable, par les techniques de contrainte qu’il exerce sur ses sujets, à une organisation criminelle – abstraction faite des valeurs promues ou poursuivies par tel ou tel appareil étatique.

Le présent projet de communication propose une étude sur la manière de représenter la violence ainsi que son instrumentalisation à des fins personnelles dans des actes relevant de la pratique notariale aux XVIIe et XVIIIe siècles à Liège. L’analyse de ces sources est novatrice pour une histoire de la criminalité. En effet, les historiens se sont avant tout centrés sur les archives des cours judiciaires. Il semble cependant que les populations d’Ancien Régime n’allaient pas systématiquement devant le juge pour régler leurs conflits. Ainsi des accords, qui ne seraient sans doute jamais parvenus à la connaissance de l’historien par la seule étude des archives criminelles, émergent dans les actes relevant de la pratique notariale. Outre ces accommodements clairement identifiés dans les minutes, les populations d’Ancien Régime se déplacent également devant notaires pour que ceux-ci retranscrivent, plus ou moins fidèlement, le récit subjectif d’un évènement vécu. Ces déclarations criminelles seront ensuite, selon le choix du comparant, enregistrées ou non au greffe. En effet, cette trace d’accusation ou de témoignage ne parvient pas systématiquement aux autorités. Tout dépend de l’évolution du conflit et parfois le simple déplacement chez le notaire pousse la partie adverse à s’accommoder avant le passage en justice. Ces déclarations criminelles constituent des sources particulièrement intéressantes pour observer la psychologie, les perceptions et les interprétations de la violence des victimes et des agresseurs. Nous proposons ici d’étudier les stratégies discursives mises en œuvre lors de la passation d’une déclaration devant le notaire et sur ce qu’elles révèlent de la société qui les produit. En effet, ces témoignages constituent une véritable mise en scène de la violence, qui est instrumentalisée afin d’obtenir gain de cause lors d’un conflit. Comment les comparants s’y prennent-ils ? Quels sont les topoï les plus souvent utilisés ? Observe-t-on une évolution de ces discours entre le XVIIe et le XVIIIe siècle ? Cette analyse permettra de mettre en lumière la manière dont la société attribuait différents seuils de gravité à des actes violents, leurs circonstances aggravantes et comment ces représentations de la société étaient sciemment utilisées par les intervenants pour déconstruire la gravité de leurs actes. Enfin, étudier la violence et les discours des personnes impliquées permet également une meilleure compréhension de phénomènes sociaux que nous proposons de souligner, comme l’importance de l’honneur et sa place essentielle dans la société d’Ancien Régime.

Drowsiness is a major cause of accidents, in particular in road transportation. It is thus crucial to develop robust drowsiness monitoring systems. There is a widespread agreement that the best way to monitor drowsiness is by closely monitoring symptoms of drowsiness that are directly linked to the physiology of an operator such as a driver. The best systems are completely transparent to the operator until the moment he/she must react. In transportation, cameras placed in the passenger compartment and looking at least at the face of the driver are most likely the best way to sense physiology related symptoms such as facial expressions and the fine behavior of the eyeballs and eyelids. We present here the new database (available on http://www.drozy.ulg.ac.be) called DROZY that provides multiple modalities of data to tackle the design of drowsiness monitoring systems and related experiments. We also present two novel systems developed using this database that can make predictions about the speed of reaction of an operator by using near-infrared intensity and range images of his/her face.

Wearable inertial systems often require many sensing units in order to reach an accurate extraction of temporal gait parameters. Reconciling easy and fast handling in daily clinical use and accurate extraction of a substantial number of relevant gait parameters is a challenge. This paper describes the implementation of a new accelerometer-based method that accurately and precisely detects gait events/parameters from acceleration signals measured from only two accelerometers attached on the heels of the subject’s usual shoes. The first step of the proposed method uses a gait segmentation based on the continuous wavelet transform (CWT) that provides only a rough estimation of motionless periods defining relevant local acceleration signals. The second step uses the CWT and a novel piecewise-linear fitting technique to accurately extract, from these local acceleration signals, gait events, each labelled as heel strike (HS), toe strike (TS), heel-off (HO), toe-off (TO), or heel clearance (HC). A stride-by-stride validation of these extracted gait events was carried out by comparing the results with reference data provided by a kinematic 3D analysis system (used as gold standard) and a video camera. The temporal accuracy ± precision of the gait events were for HS: 7.2 ms ± 22.1 ms, TS: 0.7 ms ± 19.0 ms, HO: ‒3.4 ms ± 27.4 ms, TO: 2.2 ms ± 15.7 ms, and HC: 3.2 ms ± 17.9 ms. In addition, the occurrence times of right/left stance, swing, and stride phases were estimated with a mean error of ‒6 ms ± 15 ms, ‒5 ms ± 17 ms, and ‒6 ms ± 17 ms, respectively. The accuracy and precision achieved by the extraction algorithm for healthy subjects, the simplification of the hardware (through the reduction of the number of accelerometer units required), and the validation results obtained, convince us that the proposed accelerometer-based system could be extended for assessing pathological gait (e.g., for patients with Parkinson’s disease).

The present paper addresses the problem of modal identification of time-varying systems. The identification is based on a multivariate autoregressive moving-average model in which the time variability of the system is caught using a basis functions approach. In this approach, the time-varying regressive coefficients in the model are expended in the chosen basis functions and only the projection coefficients have to be identified. In that way, the initial time-varying problem then becomes a time-invariant one that can be solved. Because a multivariate model is used, in addition to the time-varying poles, the time-varying mode shapes may be identified too. The method is first presented and then applied on an experimental demonstration structure. The experimental structure consists of a supported beam on which a mass is travelling. The mass is chosen sufficiently large to have a significant influence on the dynamics of the primary system. This kind of problem is a classical example commonly used by many authors to test time-varying identification methods. [less ▲]

Recent advances in agent-based micro-simulation modelling have further underlined the importance of a thorough full synthetic population procedure to guarantee a correct characterization of the true population. We propose an integrated approach including Markov Chain Monte Carlo (MCMC) simulation and profiling based methods to catch the complexity and the diversity of agents of the true population through representative micro samples. The population synthesis method is capable of building the joint distribution of a given population with its corresponding marginal distributions (e.g. age, gender, socio-professional status etc.) using complete, partial conditional probabilities or both of them at the same time. Particularly, the estimation of socio-demographic variables and characterization of daily activity-travel patterns are included within the framework. Data stemming from the 2010 Belgian Household Daily Travel Survey (BELDAM) are used to calibrate the modelling framework. We illustrate that this framework catches in an efficient way the behavioral heterogeneity of travelers. Furthermore, we show that the proposed framework is adequately adapted to build large scale micro-simulation scenarios of transportation and urban systems. [less ▲]

The international conference « encore l'architecture – encore la philosophie » is an initiative of the GERPHAU lab, research group for Philosophy, Architecture, Urban (Architecture School of Paris La Villette, UMR 7218 CNRS-Lavue), in partnership with Cité de l'architecture et du patrimoine, UMR-Lavue (Laboratoire Architecture, Ville, Urbanisme, Environnement) and philAU (a scientific thematic network : Philosophy, Architecture, Urban). This conference is the first ARENA conference (Architectural Research in Europe Network Association), a shared platform that aims to promote, support, develop and disseminate high-quality research in all fields of architecture in the widest sense. The network already includes researchers from leading European architecture schools. Synopsis. In Paris in 1987, a first event was held to celebrate the meeting of two disciplinary fields, entitled “Mesure pour mesure, architecture et philosophie”. Architects and philosophers were invited to discuss together how philosophy could capture better what determines architecture itself. Now, on the occasion of a new international conference, the GERPHAU Lab seeks to restate and refresh the question of the meeting of architecture and philosophy, by asking: what still remains today of our cross-over practices? ENCORE L'ARCHITECTURE, ENCORE LA PHILOSOPHIE. To build together these reflections about the future of our respective practices, why don't we hold to the hypothesis that our recent histories, in architecture as well as philosophy, could be written through the addition of a few prefixes? In linguistics, a prefix does not only serve the formation of a new word: it also regenerates the question of the meaning of the word. It is a discursive invention and its real strength lies in its ability to engage a new type of relationship with the world. Re-, alter-, eco-, co-, bio-, etc., these prefixes have clung to both our discourses as well as our disciplines. But in what way do they question the meaning of our practices? In archi-tecture as in philo-sophy, how do these successive re-definitions put the fundamentals into question, and how do they disturb their alleged unity inherited from Ancient Greece? And, moreover, how does the over-use of prefixes help us to understand what still makes sense in philosophy, or what still makes sense in architecture? The key issue of this conference, ‘Encore l'architecture, Encore la philosophie’, will be to trace backwards the stream of architectural and philosophical ideas through the thematic of the prefix as constituting a form of narrative. The conference will aim to trace the paths of their development, and other influencing factors, so as to return to those meetings between architecture and philosophy which already have oriented, re-oriented and sometimes dis-oriented our speech. It will be a meeting at which we invite participants to retell the story of our disciplines in order to grasp what it is still unique today about our practices. [less ▲]

The β Cephei pulsating stars present a unique opportunity to test and probe our knowledge of the interior of massive stars. The information that we can get depends on the quality and number of observational constraints, both seismic and classical ones. The asteroseismology of β Cephei stars proceeds by a forward approach, which can result in multiple solutions, without clear indication on the level of confidence. We seek a method to derive confidence intervals on stellar parameters and investigate how these latter behave depending on the seismic data accessible to the observer. We realise forward modelling with the help of a grid of pre-computed models. We also use Monte-Carlo simulations to build confidence intervals on the inferred stellar parameters. We apply and test this method in a series of hare and hound exercises on a subset of theoretical models simulating observed stars. Results show that a set of 5 frequencies (with knowledge of their associated angular degree) yields precise seismic constraints. Significant errors on the determination of the extent of the central mixed region may result when the theoretical models do not present the same chemical mixture as the observed star. [less ▲]

For more than 25 years now, traceroute has demonstrated its supremacy for network-path measurement, becoming the most widely used Internet path diagnosis tool today. A major limitation of traceroute when the destination is not controllable by the user is its inability to measure reverse paths, i.e., the path from a destination back to the source. Proposed techniques to address this issue rely on IP address spoofing, which might lead to security concerns. In this paper we introduce and evaluate DisNETPerf, a new tool for locating probes that are the closest to a distant server. Those probes are then used to collect data from the server point-of-view to the service user for path performance monitoring and troubleshooting purposes. We propose two techniques for probe location, and demonstrate that the reverse path can be measured with very high accuracy in certain scenarios. [less ▲]

Using deep neural nets as function approximator for reinforcement learning tasks have recently been shown to be very powerful for solving problems approaching real-world complexity. Using these results as a benchmark, we discuss the role that the discount factor may play in the quality of the learning process of a deep Q-network (DQN). When the discount factor progressively increases up to its final value, we empirically show that it is possible to significantly reduce the number of learning steps. When used in conjunction with a varying learning rate, we empirically show that it outperforms original DQN on several experiments. We relate this phenomenon with the instabilities of neural networks when they are used in an approximate Dynamic Programming setting. We also describe the possibility to fall within a local optimum during the learning process, thus connecting our discussion with the exploration/exploitation dilemma. [less ▲]

Les nouvelles techniques LiDAR (Light Detection and Ranging) et photogrammétriques permettent d’acquérir rapidement un volume important de données 3D. Le terme LiDAR désigne tout instrument de mesure (terrestre, aéroporté) basé sur l’analyse des propriétés d’un faisceau renvoyé vers un émetteur (Poux et al. 2014). Conscient de l’énorme potentiel de ces techniques, l’Unité de Géomatique de l’Université de Liège a réalisé la numérisation de la Cathédrale Saint‐Paul de Liège. Ce projet a été initié via une collaboration avec le Matthieu Piavaux (FUNDP) et financée par le FNRS. Au‐delà des aspects de conservation et d’analyse du bâti, cette numérisation nous a permis de mettre en lumière les principes et limitations de la technique même d’acquisition de données 3D via LiDAR ainsi que ses limitations tant matérielles (sur terrain) que logicielles (traitement des données). Le jeu de donnée obtenu de la numérisation sert également de base fondamentale à un ensemble de projets de recherches (notamment via la réalisation de thèses de doctorats) visant à la segmentation automatique de nuages de points, de reconstruction d’objets tridimensionnelles, d’analyse de qualité d’ajustements. Par la suite, nous détaillons la méthodologie utilisée pour l’acquisition du nuage de points 3D ainsi que les différents principes de calage de nuages. Le chapitre suivant sera consacré à la présentation de résultats ainsi que de premiers développements en termes de segmentation automatique. Finalement, nous dresserons quelques perspectives de représentations. [less ▲]

This paper proposes a network proximity service based on the neighborhood models used in recommender systems. Unlike previous approaches, our service infers network proximity without trying to recover the latency between network nodes. By asking each node to probe a number of landmark nodes which can be servers at Google, Yahoo and Facebook, etc., a simple proximity measure is computed and allows the direct ranking and rating of network nodes by their proximity to a target node. The service is thus lightweight and can be easily deployed in e.g. P2P and CDN applications. Simulations on existing datasets and experiments with a deployment over PlanetLab showed that our service achieves an accurate proximity inference that is comparable to state-of-the-art latency prediction approaches, while being much simpler.

This study investigated the determinants of financial inclusion for small scale farmers by focusing on the access to formal and informal agricultural credits in the Southern Province of Rwanda. Data were collected from 310 farmers from Huye and Nyamagabe districts through an open-ended structured questionnaire and analysed using the binary logistic regression method. The major findings, on one hand, showed that among the requested and approved agricultural loans, 87.2% and 12.7% were from informal and formal financial institutions respectively. Among those who accessed agricultural credits, 59.7% were from Huye and 40.3% from Nyamagabe. On the other hand, it was revealed that the household characteristics and the community attributes are the most important determinants. Those household characteristics include household income and expenditure, Ubudehe socio-economic category of the household, off-farm employment and the size of the land owned by the household whereas community attributes involve residence area, transport and informal financial services availability. Regarding farmer characteristics, the education level was found to be the only factor affecting the smallholder farmers' access to agricultural credit. In light of the findings, it was recommended to conduct sensitization sessions focusing on the importance of agricultural credits for smallholder farmers especially in the areas with high level of poverty. In addition, there is need to work on alleviating the formal agricultural credits access barriers, and to conduct a study on the dynamics of informal and formal agricultural credits up take and usage by smallholder farmers to explore all dimensions of financial inclusion in the study area.

Metabolomics is one of the most recent technologies in the Omics sciences defined as “the comprehensive characterization of small molecules (called metabolites) in different biological samples.” This methodology can be applied in many areas, such as biomarker discovery, clinical studies, drug efficacy and toxicity evaluation, diagnostic tools, quality control or drug discovery. Its capability to extract biochemical information associated with a cellular or biological system makes this technique a powerful tool for Medicinal Chemistry. In this work, we present a 1H NMR metabolomics study applied to therapeutic target discovery. Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly population of industrialized countries. This blindness results from the deterioration of the macula, a small part of the retina specialized for the high-acuity vision. Exudative AMD, called “wet”, is characterized by the formation of new blood vessels growing under the retina according to a process named choroidal neovascularization (CNV). Currently, the aetiology and pathogenesis of AMD remain unclear. Nevertheless, a recent metabolomics study performed on the serum of “wet” AMD patients and on a CNV murine model, that mimics the effect of “wet” AMD, have demonstrated that lactate level is clearly involved in the severity of the pathology as well as the relationship between lactate, CNV and AMD. According to this result, we suggest a new therapeutic approach of AMD based on the normalization of blood lactate level. The modulation of the lactate plasma concentration by treatment of the animals with synthetic compounds and more specifically Pyruvate Dehydrogenase Kinase (PDK) inhibitors significantly decrease the CNV. Starting from these results, development of new PDK inhibitors could open the way to innovative treatment opportunities in AMD disease. [less ▲]

The assessment of adaptive facades presents a challenge because there is no established evaluation strategy to systematically reach this goal and many of the available building energy standards and codes have limited applicability for such advanced facades system. This paper reviews current evaluation methods for assessing adaptive facades system through a literature review. It also discusses occupant behaviour, post occupancy evaluation and commissioning issues and presents the procedures. The paper is part of the activities of Working Group 3 in COST Action TU1403 - Adaptive Facades Network. So far we could not find a protocol for assessment of adaptive facades. The reviewed literature is scattered lacking a focus on adaptive facades. There is no agreement on defining what are adaptive facades (sometimes named intelligent, smart, dynamic). We could define specialized technology monitoring techniques to assess the performance of technologies such as fabric-integrated solutions (e.g. electrochromic glazing, phase-change materials, building-Integrated Photovoltaics with heat recovery (BIPV/T, shade shutters) and advanced controls. The review is used to identify gaps in existing assessment methods and helps develop strategies for the holistic evaluation and assessment of adaptive facade systems as part of high performance buildings.

« Il ne faut pas travailler pour un monde qui disparaît mais pour un monde nouveau dont on peut prévoir l’avènement ». Architecte par vocation et formation, puis commerçant, ensuite créateur et industriel, le Liégeois Gustave Serrurier (1858-1910) est rapidement convaincu de la nécessité de lier l’architecture aux arts décoratifs. Il le fait avec la conviction politique et esthétique qu’une production industrialisée permettra de donner au plus grand nombre l’environnement artistique auquel tout être peut prétendre. Il pressent que le temps de l’artisanat est en passe d’être révolu et équipe progressivement ses ateliers de machines modernes. Si ses premières créations restent empreintes de l’esprit constructif des artisans néogothiques, s’il emploie ensuite des jeux de lignes courbes, tendues et maîtrisées, le début du XXe siècle le voit évoluer vers toujours plus de simplicité constructive et plus de rigueur géométrique. Grâce au mobilier, aux objets et aux aménagements d’intérieurs qu’il crée et fait réaliser par la centaine d’ouvriers de ses ateliers liégeois, sa firme prend rapidement une ampleur internationale et se fait remarquer dans les expositions universelles comme celle de Saint-Louis (U.S.A.) en 1904. Anticipant sur ce que seront les motivations d’un Bauhaus, ses préoccupations sociales et esthétiques conduisent Serrurier à imaginer un mobilier de plus en plus économique, rationnellement construit, adapté à l’usage et au lieu de destination, par exemple pour une habitation ouvrière à l’Exposition universelle de Liège en 1905. Là, un mobilier en orme équipe la salle commune égayée d’une frise au pochoir et de rideaux de lin garnis de carrés colorés. On y remarque un meuble à usage multiple, tout à la fois armoire, secrétaire et bibliothèque, sans autre décor que sa composition équilibrée ; banc, table et chaises sont faits d’éléments assemblés par des vis apparentes. C’est à cette même époque que Serrurier développe la ligne “Silex”, particulièrement représentative ; conçue de façon tout à fait originale et pragmatique, exécutée en bois blanc et décorée au pochoir, la plupart des assemblages de menuiserie sont remplacés par des vis apparentes. La découpe des planches se montre économe en matière. Une chaise, objet d’utilité commune, se doit d’être robuste, ergonomique et peu coûteuse à produire : ici, la production en série est aisée et pourra être assurée dans ses ateliers équipés de scies mécaniques et autres machines-outils. A l’examen, une chaise de cette série exprime bien les qualités de designer industriel de son concepteur et le place à l’avant-garde de son temps ; elle illustre aussi ses ambitions, tant sociales qu’esthétiques, et sa volonté d’un « art pour tous ».

Abstract A l'extrême fin du 19e siècle, l'Art nouveau s’épanouit sous des formes diversifiées, parfois contradictoires, mais partageant généralement la même volonté de rompre avec l'académisme et l'historicisme du siècle finissant. Parmi les acteurs de cet Art nouveau, certains ne retiennent que le côté décoratif d’une nouvelle esthétique. Très tôt cependant, au cœur même de ce mouvement d’avant-garde, apparaissent les prémices du renouvellement qui le condamnera et conduira au Modernisme.

The offshore wind energy development is highly affected by the condition of the weather at sea. Hence, it demands a well-organized planning of the overall process starting from the producers’ sites until the offshore site where the turbines will finally be installed. The planning phase can be supported with the help of Discrete Event Simulation (DES) where weather restrictions, distance matrix, vessel characteristics and assembly scenarios are taken into account. The purpose of this paper is to simulate the overall transport, assembly and installation of the wind turbine components at sea. The analysis is carried out through DES considering both the real historical weather data (wind speed and wave height) and probabilistic approach. Results of the study, applied to the real Offshore Wind Farm (OWF) configuration, are showing a good agreement between the two proposed models. The results point out that the probabilistic approach is highly affected by the semi-random numbers used to model the stochastic behavior of the input variable so that several iterations (200 to 400) are required to reach the convergence of the simulation outputs. We suggest that seasonality of the outputs of both models are preserved, i.e. the variation of the results depending on the variation of the weather along the year. These findings provide a new framework to address risks and uncertainties in OWF installations. [less ▲]

This work presents an analysis of the behaviour of different structural members under natural fires, with the aim to characterize their sensitivity to the fire decay phase. Thermo-mechanical numerical simulations based on the non-linear finite element method are conducted using the parametric fire model of Eurocode to represent the natural fires. Results show that, for all the studied members (column, beam) and materials (reinforced concrete, steel, timber), structural failure during or after the cooling phase of a fire is a possible event. The major factors that promote delayed structural failure are the thermal inertia and the constituting material of the member. An indicator is proposed to quantify the propensity to delayed failure for structural members under natural fire. This work enhances the understanding of the structural behaviour under natural fires and has implications for the safety of the fire brigades and people proceeding to a building inspection after a fire.

In this paper is presented the analysis of a concrete building exposed to OZone fire. The temperature development in the elements and the structural behaviour were calculated in SAFIR using beam elements for the columns and beams and shell elements for the floor slabs. The first floor was modelled and the effects of action from the upper storeys are applied as external loads. It is shown how the numerical analysis allows understanding the behaviour of the structure when exposed to a natural fire until complete cooling by analysing the evolution of displacements, the distributions of bending moments in the beams, the membrane forces in the slab, and the stresses in the elements. All this detailed information would not be available from an experimental test. [less ▲]

In the field of shelving structures for the storage of goods realized adopting tubular members, an interesting connection typology to be used to fasten the vertical columns to the beams is represented by bolted connections with long bolts in shear. With reference to this kind of connections, the authors have already performed a wide experimental and numerical investigation highlighting the occurrence, in this specific case, of local buckling phenomena. In this paper, the attention is focused on the influence of local buckling on the connection resistance, which is neglected by the current version of EC3 in the prediction of the resistance of shear connections of plates. In particular, starting from the results of the experimental and numerical analyses previously performed, in the present paper a formulation for predicting the bearing resistance of the examined connection able to account for the phenomenon of local instability is set up.

Over the last few years, a wide variety of background subtraction algorithms have been proposed for the detection of moving objects in videos acquired with a static camera. While much effort have been devoted to the development of robust background models, the automatic spatial selection of useful features for representing the background has been neglected. In this paper, we propose a generic and tractable feature selection method. Interesting contributions of this work are the proposal of a selection process coherent with the segmentation process and the exploitation of global foreground models in the selection strategy.

In order to study the behaviour of shallow closed-loop geothermal systems four borehole heat exchangers equipped with fiber optics were installed on the campus of the University of Liege (Liege, Belgium) over a surface area of 32m². This paper presents the analysis of continuous, high-resolution temperature profiles measured along the boreholes length. The undisturbed ground temperature measurements indicate heat loss from ground structures located close to the boreholes. A 3D numerical model is presented to reproduce the measured temperature profiles. Temperature profiles during hardening of the grouting material indicate extended fractured zones in the rock mass. Temperature measurements during the recovery phase of a Distributed Thermal Response Test indicate the succession of rock layers with different mineral content. The results are in good agreement with those of the borehole televiewer logging method. The presented analysis could provide information on bedrock heterogeneity, on the anisotropic thermal behaviour of the rock mass and on the ground temperature variations due to heat loss from ground structures. These information could significantly contribute to the long-term behaviour prediction of the geothermal system and the geothermal reservoir potential. [less ▲]

Within the concept of "vulnerability" - considered as an inherent or innate value of the human being, from which it is necessary to start in order to build a genuine social policy- the children's vulnerability occupies a special position. Traditionally, children have been treated as objects of protection and not as subjects of rights according to an authoritarian and paternalistic perspective. Over time, a different view of this matter has developed, and it has put the child at the center of attention, considering his vulnerabilities, needs and interests. This perspective has been reflected in the legislation, in case law and doctrine, both internationally and nationally. The concept of "best interest" is the key for addressing children's vulnerability of children and developing substantive equality for them. The European Court of Human Rights in Strasbourg and the Court of Justice of the European Union in Luxembourg have defined this concept in different areas: in the field of international child abduction, immigration, asylum and family reunification, custody and parental responsibility. Although these two tribunals have grounded their arguments on different legal perspectives, both have shown and still show a trend towards convergence to common points, through a balanced consideration of rights in this area. This communication aims at examining the relevant jurisprudence of the aforementioned tribunals about the notion of "best interest" of the child. The case-law since 2011 until 2015 has been taken into account. [less ▲]

Anthropogenic debris (AB) contaminate oceans and affect marine organisms in several ways. Plastic production is constantly increasing and it is estimated that 10% of this production end in the seas. As a consequence, plastic is considered as an emerging contaminant and ingestions by organisms are increasingly reported. Microdebris (< 5mm) are available for a high range of organisms, including planktivorous fish, such as the European anchovy (Engraulis encrasicolus). Planktivorous fish have a particular gill basket, with long and tight gill rakers, related to their diet. Upon these gill rakers, small structures called denticles are present. These gill rakers act as a net to trap organic particles and AB. The aim of our study was to correlate sizes of AB ingested with the mesh constituted by the gill rakers and associated structures. Fifteen stomach contents were analyzed by Raman spectroscopy and particles were measured. Five gill arches were observed with a scanning electron microscope. Cellulose fibers and microplastics were the most AB ingested. Comparing to other Clupeiformes (pilchard and Atlantic herring), anchovies have more denticles on each gill rakers (personal data). AB ingestion by fish is poorly studied and impacts of AB are not much understood. Clupeiformes play a major role in marine ecosystems and is the most consumed order by humans. As the branchial basket constitutes a food selective apparatus, more morphological studies dealing with AB ingestion on Clupeiformes are needed. [less ▲]
