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.

Nappe oscillation may affect a variety of free overflow hydraulic structures operating at low heads such as crest gates and various types of weirs. This phenomenon produces oscillations in the thin nappe cascading downstream of the control structure. These oscillations can result in a high noise levels that may affect people and structures located nearby. With long linear and thin overtopping walls, piano key weirs might be subject to strong nappe oscillation risks, as a few documented cases with labyrinth weirs. However, the specific geometric features of piano key weirs, such as the outlet ramps or the limited width of the inlet apex, could perhaps prevent the development of nappe oscillation. In this paper, a prototype-scale linear weir is operated to assess the risk of nappe oscillations on a piano key weir like configuration (sidewall). In particular, the effect of the weir width and inclined apron is analyzed. The experimental results show that nappe oscillation development should not occur on piano key weir, contrary to what might be observed on a labyrinth weir with the same crest. [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 presents a computational model of the mid-term outage scheduling process of electric power transmis- sion assets, to be used in long-term studies such as mainte- nance policy assessments and system development studies, while accounting for the impact of outage schedules on short-term system operation. We propose a greedy algorithm that schedules the outages one by one according to their impact on system operation estimated via Monte-Carlo simulations. The model is implemented in JULIA and applied to the IEEE RTS-96. [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.

In this paper we study how supervised machine learning could be applied to build simplified models of real-time (RT) reliability management response to the realization of uncertainties. The final objective is to import these models into look-ahead operation planning under uncertainties. Our response models predict in particular the real-time reliability management costs and the resulting reliability level of the system. We tested our methodology on the IEEE-RTS96 benchmark. Among the supervised learning algorithms tested, extremely randomized trees, kernel ridge regression and neural networks appear to be the best methods for this application. Furthermore, by using feature “importances” computed by tree-based ensemble methods, we were able to extract the most relevant variables to predict the response of real-time reliability management, and thus obtain a better understanding of the system properties.

En 1502, les Annonciades sont fondées en France par Jeanne de Valois, épouse répudiée du roi de France, Louis XII. La règle franciscaine dicte le mode de vie de ces religieuses. Elles sont vêtues d’un scapulaire rouge enfilé sur une robe grise, avec une voile noir. Un couvent de ces Annonciades de France, dites « rouges », est fondé à Namur en 1623. Cent ans plus tard, l’ordre des Annonciades célestes apparaît en 1602 en Italie, créé par Vittoria Fornari, dame de la petite noblesse génoise. Puisant ses préceptes dans la règle de saint Augustin, il est alors connu sous le nom de « l’ordine della Santissima Annunziata » (en français, « l’ordre de la Très Sainte Annonciade »). Ces religieuses sont identifiables par la couleur de leur costume : un scapulaire et un manteau « bleu céleste », portés sur une robe blanche et un voile noir. L’ordre gagne rapidement la France puis la Belgique. Un couvent est établi à Namur en 1631. Ces deux communautés revendiquaient donc le nom d’« Annonciades » et se côtoyèrent parfois dans une même ville. Ce fut le cas à Namur où elles s’établirent toutes les deux en moins d’une décennie. Ces circonstances offrent des dénominateurs communs pour permettre une comparaison architecturale inédite de ces deux établissements. Si le couvent des Annonciades célestes demeure partiellement conservé, celui des Annonciades rouges a disparu. Néanmoins, les sources archivistiques et iconographiques permettront de documenter l’analyse du plan de ces deux édifices ainsi que des matériaux de construction. Si le lieu d’implantation de ces bâtiments influencera probablement les techniques de construction, les différences entre les deux règles surgiront peut-être dans le plan de l’édifice. [less ▲]

Lehrer weisen ein erhöhtes Risiko auf, Stimmstörungen zu entwickeln. Sogar Lehramtsstudierende sind bereits zu etwa 20% betroffen, obwohl die stimmlichen Anforderungen während des Studiums noch gering ausfallen (vgl. Ettehad 2004). Nur unzureichend wurde bislang die Stimme von Lehrkräften im Vorbereitungsdienst (LiV) untersucht. Gleichwohl ist der Vorbereitungsdienst ein kritischer Zeitraum. LiV unterrichten etwa 12 Stunden pro Woche und stehen unter hohem Leistungsdruck. Dies kann sich potentiell negativ auf die Stimme auswirken. Ziel der Studie war es demnach, die Prävalenz und Art von Stimmstörungen bei Lehrkräften im Vorbereitungsdienst zu bestimmen. Weiterhin sollten Zusammenhänge zwischen subjektiven und objektiven stimmbezogenen Daten untersucht werden. 73 LiV nahmen an der Studie teil, die sich aus einem selbstkonzipierten Fragebogen und der Erhebung objektiver Daten zusammensetzt. Probanden, die im Fragebogen angaben, während des Vorbereitungsdienstes bereits zwei oder mehr Symptome einer Stimmstörung wahrgenommen zu haben, wurden als stimmgestört klassifiziert. Anhand objektiver Messungen wurden zudem die Variablen maximale Tonhaltedauer (THD), Jitter und Shimmer erhoben und mit den subjektiven Daten in Beziehung gesetzt. Bei 37% der Probanden ergaben sich Hinweise auf das Vorliegen einer Stimmstörung. Besonders häufig wurden die Symptome Rauigkeit, Räusperzwang oder Lautstärkeprobleme genannt. Es bestand kein signifikanter Zusammenhang zwischen den subjektiven und den objektiven Daten. Die Ergebnisse deuten darauf hin, dass angehende Lehrkräfte im Zeitraum des Vorbereitungsdienstes vermehrt zu Stimmproblemen neigen. Dies unterstreicht die Notwendigkeit von interventiven Maßnahmen, die bereits im Studium zum Tragen kommen sollten. [less ▲]

Ce projet s'est déroulé de mars 2011 à juillet 2015. Le projet comportait les objectifs suivants : (1) dresser un portrait des utilisations actuelles des céréales wallonnes ; (2) élaborer des scénarios originaux d'évaluations possibles de l'utilisation des céréales wallonnes en concertation avec le secteur wallon ; (3) évaluer, sur base d'analyses du cycle de vie (ACV), les impacts environnementaux (et socio-économiques, disponibles mais non repris dans cet article) de la production et la transformation des céréales wallonnes selon des exemples de filières de valorisation. L'article présente des informations, extraites des résultats du projet, sur le portrait en 2010 de la valorisation des céréales wallonnes et sur l'estimation de l'impact environnemental de la production de céréales en Wallonie. Il se limite à donner les conclusions et messages-clés de l'étude sur la construction de scénarios possibles d'évolution de l'utilisation des céréales wallonnes d'une part et, d'autre part, sur l'utilisation des céréales pour la production d'énergie.

In 1991, the European Union enacted a “Nitrates” directive that each member state has had to translate into an action plan in its territory. One of the tools the Walloon region uses to control the implementation of this action programme is the measure of residual nitrogen in the soil at the beginning of the nitrate leaching period (Nitrogen Leaching Potential). From 2004 to 2007, this tool was used in a hundred-odd farms that had voluntarily requested an exemption from the maximum amount of spreadable farmyard manure.

Water-repellents are increasingly used in the recent years. Those ones are generally used to reduce the degradation caused by freeze / thaw, by alkali-aggregates reaction or by chloride ions. The objective of this study is to determine if hydrophobic treatments also have an influence on the propagation of the carbonation front into the concrete. Capillary absorption tests, permeability to water-vapor and oxygen, FTIR, DSC and porosity were carried out on concrete samples. Six products with different concentrations, solvent and molecules were tested. The results showed that the application of a water-repellent delays the propagation of the carbonation front. The most efficient products were the silanes which presented a higher penetration depth. Concrete compactness and porosity played also an important role in silane penetration depth. [less ▲]

3D movies are calibrated to meet a certain screen bright- ness standard. Therefore, what would be the consequences on the quality of the 3D experience for spectators watching a 3D movie when movie theaters do not respect this standard? First, we attempted to better understand which factors were important for a spectator by conducting an experiment where participants watched a 3D movie and filled out an exploratory questionnaire. Then, we aimed to investigate the link between image brightness loss and the quality of the 3D experience as perceived by the spectator. First results show no perceived difference in the quality of the 3D experience between a nor- mal brightness and a brightness decreased by 10% for four factors, i.e. (1) the appreciation of the movie, (2) the con- tent of the movie, (3) the 3D quality of the movie, and (4) the quality of the 3D experience in general.

Shrimp value chain in Vietnam functions with a large number of farmers. The stay in the weakest position in the chain due to their small individual scale with an average land of about 0.5 ha/farm, and low skills (Ho, 2012). As a leader and holding the strongest power in the shrimp value chain, the processors determine shrimp prices and set up requirements of shrimp quality and size in the market though quality control has not been completely implemented due to the limitations of financial capital, knowledge, awareness, as well as the quality of raw material supplied by collectors and farmers. In order to help the shrimp sector to work more efficiently, the Vietnamese government brought together shrimp farmers and plant processors through a farming contract. Two years after this application, the contract farming model failed due to the floor price mechanism, risk sharing, small scale of the model while there are excess suppliers in the market, administrative misconception and inefficient public management. As a result, farmers still stay at the weakest position and the shrimp sector could not improve its product safety to adapt to the requirement of import markets. The study results recommend necessarily a planning and projection of shrimp production zones, re-organizing shrimp farmers into legal teams or groups or coopératives to increase the size of the existing shrimp cultivation units in Vietnam.

There is a need to clearly state an interaction model that formalizes interactions between actors of the distribution system exchanging flexibility. In previous works we quantitatively evaluated the performance of five interaction models devised with industrial partners using the agent-based testbed DSIMA. Simulation results showed that these interaction models relying on active network management suffer from a lack of coordination between the distribution and the transmission system operator, activating flexibility simultaneously in opposite directions. This paper introduces a new interaction model fixing this issue based on dynamic access bounds to the network changing throughout the day and preventing the activation of flexibility leading to congestions. This new interaction model is implemented in DSIMA and compared to a model restricting the grid users to a very restrictive but safe access range. Results show that this new model allows to safely increase by 55% the amount of distributed generation in the network. [less ▲]

Cette communication exposera une pratique d’évaluation formative mutuelle proposée dans le cadre d’un cours sur les dispositifs pédagogiques de lutte contre le décrochage et l’exclusion adressé aux étudiants de Master. Cette pratique vise à accompagner les étudiants dans la réalisation d’un travail de groupe ayant pour tâche d’analyser un dispositif pédagogique de lutte contre le décrochage. Pour les aider dans la réalisation, deux moments clés structurent l’accompagnement : une rencontre avec les encadrantes pour discuter et valider la démarche envisagée et des « tables de discussion » centrées sur l’évaluation formative mutuelle du travail collectif à produire (travail dit « intermédiaire » rédigé au plus près de la version finale attendue). L’objectif de ces tables pour chaque groupe est double : permettre de prendre de la distance par rapport à sa propre production écrite et de profiter du regard extérieur apporté par les autres groupes pour enrichir son propre travail. Les lectures d’autres rapports intermédiaires et le feedback apporté par chaque membre de la table de discussion sont en effet autant de nouvelles sources de réflexion. Ces nouveaux apports permettent notamment de clarifier l’attendu par rapport aux critères d’évaluation finaux et de retravailler le contenu (Mottier Lopez, 2015). Concrètement, chaque étudiant est amené à évaluer, par écrit, sur base d’une grille reprenant les critères et indicateurs d’évaluation du travail final, deux à trois travaux intermédiaires. Lors de cette phase de lecture, l’étudiant relève tant les éléments positifs que négatifs identifiés et formule, pour ces derniers, des pistes concrètes d’amélioration. Lors des tables de discussion, le timing est prévu de façon à octroyer à chaque groupe présent un temps égal d’échanges autour des lectures et évaluations formatives réalisées par chaque participant présent. La communication décrira le dispositif d’évaluation formative et présentera les données recueillies auprès des étudiants concernant l’utilité du dispositif. [less ▲]

Une partition s’est opérée dans la gestion de l’environnement (en termes de domaine d’expertise et d’espaces dédiés) entre la nature remarquable, dont se préoccupe principalement le monde de la protection de la nature (gestionnaires d’espaces protégés et associations de protection de la nature), et la nature ordinaire sur laquelle se focalise le monde de la chasse. Or, par leur mobilité et leur capacité à transgresser les frontières, les animaux interrogent parfois cette partition et parviennent à relier ces deux formes de nature et, avec elles, leurs experts. Dans le cas de la Réserve Naturelle Régionale (RNR) de Saint Bonnet, les sangliers, qui circulent entre l’espace protégé et sa périphérie, font émerger un problème commun à ces deux mondes a priori peu reliés. Comment se rencontrent les savoirs et les expertises de ces mondes ? La gestion du sanglier parvient-elle à provoquer des rapprochements entre les divers savoirs sur la nature, voire à induire leur articulation ? En répondant à ces questions, nous illustrerons trois types de « contradictions » qui se manifestent à l’échelle collective et individuelle. Nous montrerons d’abord que la confrontation de ces experts et expertises s’inscrit dans deux mouvements parallèles et potentiellement contradictoires autour de la production de connaissances sur la nature : l’émergence d’une tendance cosmopolitique, qui prend en compte d’une diversité de savoirs, et un mouvement de professionnalisation de certains acteurs de l’environnement. Le croisement de ces deux mouvements engendre ensuite des controverses qui révèlent différentes formes d’oppositions entre les expertises ancrées dans l’expérience et celles ancrées dans l’expérimentation. Enfin, ces oppositions révèlent elles-mêmes des contradictions dans les arguments et les pratiques de chaque acteur. [less ▲]

The repair of concrete requests specific preparation operations needed for guaranteeing compatibility between substrate and new materials as well as the development of adhesion properties. These specification guidelines contain design and construction recommendations for surface preparation of concrete for repair and overlay. The paper summarizes current knowledge, best practices and results of the research concerning the surface preparation of concrete prior to application of repair/overlay materials. The specifications are applicable to repairing damaged or deteriorated concrete structures, correcting design or construction deficiencies, or upgrading a structure for new uses, or to meet more restrictive code requirements. This is based on 10 years research activities on this topic through scientific cooperation programs between Wallonia, Quebec and Poland and support of American Concrete Institute. [less ▲]

Future Internet has been a hot topic for the last decade. One of the approaches put forward in order to revise the Internet architecture is LISP~--~Locator/ID Separation Protocol, which leverages the separation of the identifier and the locator roles of IP addresses. Contrary to the classical push model used by the BGP-based routing architecture, LISP relies on a pull model. In particular, routing information is pulled from a new network element, the Mapping System, to provide the association between the identifier (i.e., the address used to identify a host inside a domain) and a list of locators (i.e., the addresses to locate an attachment point) upon an explicit query. In this paper, we evaluate a LISP Mapping System deployment in the public LISP Beta Network from two standpoints: Stability and Consistency. Our measurements show that the mapping information is stable over time and consistent between the different mapping entities and the vantage points. Our analysis shows that there are cases where the Mapping System is unstable and/or inconsistent, hence, beside proposing a taxonomy in order to classify them, we carry out an in-depth investigation of such cases so to provide hints on how to improve the performance of LISP.

This paper presents an analytical framework for classifying information systems developed for applications in the cultural heritage field. These can be numerous and quite different from one another, depending for the purpose they were developed for. In order to assess if one of the already existing systems can be used or modified to fit our research goals, a list of requirements was established. Starting from those, categories were defined and the information systems are then compared and evaluated based on those characteristics. This analytical framework is an important step in our research since using a tool that is not appropriate for the study object will not be able to provide valuable information to answer the main research questions.

Through the case study of the artistic copying network around the tomb of Pahery in Elkab (EK 3), the paper aims at illustrating the circulation of knowledge via iconographic patterns in Ancient Egypt. As will be underlined, this phenomenon is closely linked with the creativity process. After describing the different tombs related to EK 3, we will attempt to reach two artists’ individualities behind the iconographic programs of those funerary chapels. Finally, in order to create “analogy-bridges” which may provide food for thought for Egyptology, the productive copy process and the creativity notion will be briefly compared with the Western Renaissance context.

Although a key-concept in Art historical discourse and reasoning, creativity has almost always been avoided as an issue in the discussion of Ancient Egyptian Art, as if the notion was simply irrelevant in such a context. This surprising phenomenon has clearly deep roots in the history of the western vision of Ancient Egyptian Art (and civilization). Nonetheless, the investigation of some (actually quite rare) cases of true copies in Ancient Egyptian Art reveals that creativity operated within a process of reinterpretation of previous works and their tradition, a process that can be best described and analyzed, it seems, with the help of the conceptual frame of intericonicity (or interpictoriality). The paper also aims to defend the use of this notional tool in the analysis of Ancient Egyptian Art by attempting to define how creativity was conceived in Ancient Egyptian textual claims for innovation and originality [less ▲]

This work aims at developing, optimizing and controlling a hybrid solar microgrid for rural electrification and heat supply in sub-Saharan Africa. The considered system includes PV panels, Parabolic Trough Collectors, ORC and LPG generator, as well as battery and thermal energy storage. A special focus is paid to the co-optimization of the thermal and electrical load satisfaction since it can improve the overall energy efficiency of the system. To that end, different sub-component models are developed: - A building model to predict thermal loads of a health clinic in rural communities of Lesotho. - A microgrid model built by interconnecting the subcomponent models. - A rule-based control strategy, dispatching heat and electrical powers of each component to cover the demand while minimizing the fuel consumption. - A particle-swarm optimization of the microgrid under different cost assumptions. For the studied community of Ha Nkau in Lesotho, the determined optimal system infrastructure is composed of PV (66 kW) and batteries (262 kWh), and the optimum control strategy achieves a levelized cost of electricity of 0.203 USD/kWh. Fuel consumption is mainly due to the burner, which supplies most of the thermal load together with CSP (66 m2) and TES (86 kWh). [less ▲]

The Oule dam spillway (France) is made of a lateral weir on the right bank of the reservoir, a collecting channel, a macro-steps channel and a downstream lateral weir for water release in the natural river bed. This spillway presents a deficit in discharge capacity. In order to solve this problem, several rehabilitation solutions have been analyzed. From this process, a piano key weir solution to improve the discharge capacity of the lateral upstream weir has been selected. This piano key weir will replace the existing ogee crest while keeping weir level and thus normal reservoir elevation constant. The piano key weir, 1 m high, has been designed with steel and is made of 22.5 units for a total width of 33 m. Its main advantage is to drastically increase the discharge capacity at low heads, enabling the release of the design flood peak discharge just below the reservoir maximum elevation by optimizing the reservoir temporary storage.

The Piano Key Weir (PKW) is a rectangular-labyrinth-type weir that utilizes cantilevered apexes in order to maximize the allowable weir length that can fit in a given spillway channel width, while reducing the required structural footprint. These features make it an interesting and viable solution for increasing discharge capacity at existing dams as well as new projects. Since the early works at the University of Biskra in 2000, numerous re-search and development works have been carried out in several laboratories to understand the PKW hydraulic behavior, optimize its design and prove its advantages and drawbacks. Beside, more than 25 PKWs are now in operation or under construction all over the world. This paper aims at summarizing the information available to date about PKW hydraulics in order to provide a synthetic overview and a reference list to students, researchers and practitioners and thus help them to understand how such a complex structure operates and what could be the possible further steps in research and development.

In the framework of a RFCS project entitled “FREEDAM -Free From Damage Connections”, innovative friction connections activated as dissipative zones in case of seismic actions are studied, with the objective to avoid any damage in the structures not only for frequent and occasional seismic events, but also for destructive earthquakes. These friction connections are made of stainless steel plates with specific coatings fastened with preloaded bolts placed in long slotted holes allowing significant displacement of the plates when the friction resistance is reached and so allowing significant dissipation of energy. As a partner of this project, The University of Liege is in charge of proposing analytical design procedures for these innovative joints and in particular of investigating the evolution of the prestressing in the bolts according to time, a key parameter when it is intended to dissipate energy through the activation of friction. This paper presents first preliminary results obtained through long term tests (5 months) performed on steel plates with particular coatings fastened with M20 Bolts. The main parameters registered during these tests were the relative displacements between the connected plates and the evolution of the prestressing in the bolts. The tests were performed according to EN 1090-2, in order to assess the loss of preloading over time and the creep of the plate. The final objective of the conducted studies is to propose a methodology to predict the prestressing loss in order to ensure that a minimum level of prestressing is kept over the full life of the structures, i.e. at least 50 years.

Grazing is a Mediterranean tradition with an unvaried importance in northern Morocco. Rangeland has known profound changes, inducing a major gap between pastoral supply and demand. This study aimed to assess pastoral production of pastures at two sites in northern Morocco (Derdara and Loubar) and investigate their use by goats. Concerning biomass production, we used the method of the reference module. The surveys were realized during the biomass evaluation period. Pastoral species, mainly Arbutus unedo, Cistus monspeliensis, Erica arborea, Lavandula stoechas and Pistacia lentiscus, represent the most palatable species selected by goats. Grazing is practised throughout the year except during rainy days when breeders practice ‘cut and carry’ of the branches. The biomass produced was estimated at 1,455 and 333 kg dry matter ha‑1, respectively, in Derdara and Loubar. Significant differences were observed depending on the season and according to sampling sites. Furthermore, the research showed the appearance of degraded areas dominated by annual species together with species of low pastoral interest – thorny plant species that characterize degraded areas. Due to climate changes and overgrazing, pastoral resources will have availability and quality reduced. The reasonable use of pastures, including a reduction in grazing pressure, should be developed to insure their sustainability. [less ▲]

For several years, the number of Global Navigation Satellite Systems (GNSS) has been increasing, opening new perspectives in the field of precise positioning. Particularly, the European system, Galileo, is experiencing a prompt expansion with the launch, in 2015 and 2016, of 8 satellites belonging to the new Full Operational Capability (FOC) generation. Broadcasting new signals, with new modulations, the first studies addressing this system reveal promising level of precisions on both code and carrier phase observables. Yet, Galileo is far from being the only GNSS undergoing a noteworthy revolution. Alternatively, the Chinese program BeiDou, still in a developing phase, as well as the American GPS, currently undergoing a modernization of its signals, also knew major progress these last two years. Indeed, 7 new satellites have reached the initial BeiDou constellation, bringing to 20 the number of active satellites. Among them, 5 spacecraft inaugurated the Phase III generation, broadcasting the new B1, B2 and B3 signals. Regarding GPS, the block IIF, made of L5 signal broadcasting satellites, kept expanding but at a less steep rate than BeiDou or Galileo. In this study, we first estimated the individual precisions of each signals broadcast by the aforementioned GNSS. For this purpose, we created two short baselines of approximatively 5 meters between similar type receivers. We combined their measurements to form double differences, leaving in the position equations only multipath and receiver noise. The great expectations regarding Galileo’s quality turned into affirmations as long as we studied this system. As a matter of a fact, the code pseudoranges values of the 4 signals of Galileo we have considered (E1, E5a, E5b, E5a+b) presented outstanding precisions (from 5 to 17 centimetres on code pseudoranges with an elevation mask of 10 degrees) when compared to GPS (from 12 to 20 centimetres on codes pseudoranges) and BeiDou (from 26 to 40 centimetres for codes and for phases) in identical conditions. Even though the precision of Galileo observables is noticeable, the influence of the poor geometry of the satellite constellation degrades in a significant way the resulting precision of the position estimated, no matter the recent increase in the number of satellites. Indeed, in this incomplete constellation, the addition of new satellites results in longer visibility period but not in larger number of satellites observed at a single epoch. Combining Galileo with GPS or BeiDou is a way to solve this issue, as the three systems have been designed to be compatible. Therefore, multi-GNSS relative positioning based on overlapping frequencies should entail better accuracy and reliability in position estimations. However, the differences between satellite systems induce inter-system biases (ISBs) inside the multi-GNSS equations of observation. The overlapping frequencies of these GNSS are the L1 and L5 frequencies of GPS with the E1 and E5a signals of Galileo, respectively. As far as BeiDou is concerned, the B2 signal of emitted by the Phase II BeiDou satellites corresponds to the E5b frequency of Galileo. Regarding the new Phase III satellites, the B2 frequencies will correspond to the Galileo E5a+b signal and B1 of BeiDou will be compatible with E1 of Galileo and GPS. The combined use of these overlapping frequencies in zero baseline double differences (ZB DD) based on a unique pivot satellite is employed to resolve ISBs. This model removes all the satellite- and receiver-dependent error sources by differentiating and the zero baseline configuration allows atmospheric and multipath effects elimination. We conducted this study on the L1/E1, L5/E5a, B1(phase II)/E5b overlapping frequencies. Our receivers were not able to receive the phase III signals of BeiDou satellites. An analysis of the long-term stability of ISBs (GPS- Galileo and Galileo - BeiDou) was conducted on various pairs of receivers over large time spans. The possible influence of temperature variations inside the receivers over ISB values was also investigated. Our study is based on the 6 multi-GNSS receivers (2 Septentrio PolaRx4, 1 Septentrio PolaRxS, 1 Septentrio PolaRx5 and 2 Trimble NetR9) installed on the roof of our building in Liege. The estimated ISBs are then used as corrections in the multi- GNSS observation model and the resulting accuracy of multi-GNSS positioning is compared to GPS, Galileo and BeiDou standalone solutions.

Justification: Lors du traitement par surfactant dit moins invasif (Less invasive surfactant therapy- LIST), le produit est instillé dans la trachée par un cathéter fin alors que l’enfant respire spontanément sous CPAP. Différentes études ont donné des résultats variables mais encourageants. L’objectif de cette méta-analyse est de comparer le devenir respiratoire des prématurés traités par LIST avec celui de ceux traités par administration de surfactant par un tube endotrachéal. Méthodes : les études randomisées contrôlées (ERC) sont recherchées dans les bases de données et dans les références d’articles pertinents. Les devenirs respiratoires (dysplasie broncho-pulmonaire (DBP), décès ou DBP, échec précoce de CPAP, nécessité de ventilation invasive) et les morbidités classiques sont reprises de ces études. Pour chaque morbidité, le risque relatif (RR) des données mutualisées est calculé avec une analyse de Mantel-Haenszel à modèle d’effet aléatoire. Le RR est également calculé pour des sous-groupes établis selon l’intervention contrôle. Résultats : six ERC évaluent le LIST : 4 le comparent à l’INSURE (Intubation-Surfactant-Extubation), et les 2 autres à l’intubation (immédiate ou après maintient en CPAP) avec surfactant. Les méthodes LIST diminuent les risques de DBP (RR= 0,71 (0,52-0,99) ; nombre nécessaire à traiter NNT= 21), et de décès ou DBP (RR= 0,7 (0,58- 0,94) ; NNT= 15). L’échec précoce de CPAP et le recours à la ventilation invasive sont également réduits (RR= 0,67 (0,53-0,84) ; NNT= 8 et RR= 0,69 (0,53- 0,88) ; NNT= 6). Comparé à l’INSURE, le LIST diminue le risque combiné de décès ou DBP (RR= 0,63 (0,44-0,92) ; NNT= 11), et d’échec précoce de CPAP (RR=0,71 (0,53-0,96) ; NNT= 11). Les autres morbidités néonatales classiques sont similaires pour les différents groupes. Conclusions : une stratégie d’administration dite moins invasive de surfactant diminue les risques de morbidité respiratoire à moyen terme (DBP, décès ou DBP) et le recours à la ventilation invasive. Cette approche semble sure mais les données de suivi à long terme sont insuffisantes. [less ▲]

Introduction et objectifs : l’instillation trachéale de surfactant par un cathéter fin (Less invasive surfactant therapy- LIST) chez le prématuré sous CPAP permet de diminuer la morbidité respiratoire. Plusieurs cathéters sont décrits à cette fin : une sonde oro-gastrique insérée avec (LISA-Köln, K) ou sans pince de Maggil (Take Care- Ankara, A), un cathéter veineux de 13 cm (MIST- Hobart, H), un cathéter d’angiographie de 30 cm (Stockholm, S) ou un cathéter ombilical fixé à un stylet d’intubation utilisé localement (Liège, L). L’objectif de l’étude est d’évaluer l’efficacité de ces techniques en prenant l’INSURE (Intubation-Surfactant-Extubation) comme référence. Intervention : 20 néonatologues travaillant dans 4 services ayant des stratégies d’administration du surfactant différentes ont participé. Ils ont simulé ces 6 techniques sur deux têtes d’intubation de difficulté croissante. L’efficacité de l’intervention est évaluée par le taux d’échec et la durée de procédure mesurée sur vidéo. Chaque intervenant apprécie la facilité d’utilisation sur une échelle de 1 à 9 (Difficile> facile). Résultats : Pour le premier modèle, les durées médianes de procédure pour Köln et Ankara sont allongées [K: 21s (IQR 17-24); A: 23s (15-42); H: 10s (8-16); S: 12s (10-22); L (10-20); INSURE: 14s (11-21); p<.0001]. Pour le second modèle, seul Liège permet une durée de procédure similaire à l’INSURE [K: 32s (25-44); A: 39s (27-95); H: 34s (27-46); S: 37s (29-42); L: 24s (15-35); INSURE: 24s (17-32); p<.002]. Les taux d’échec des méthodes LIST sont similaires entre eux (de 3 à 8/ 40 essais), mais supérieurs à celui de l’INSURE (0/40). Köln et Ankara sont considérés comme plus difficiles [scores de facilité : K: 5 (4-6); A: 3 (2-4); H: 6,5 (6-7); S: 7 (4-8); L: 8 (6,5-8); INSURE: 7 (6-8); p<.001]. Conclusions : les cathéters plus rigides sont plus efficaces et perçus comme plus simples d’utilisation. L’insertion d’un cathéter guidé et incurvé pourrait être plus rapide dans les cas difficiles.

Introduction et objectifs: le positionnement adéquat d’un tube endotrachéal (TET) peut être difficile en raison de la marge de manœuvre limitée associée aux faibles distances laryngo-trachéales du prématuré. Les marqueurs distaux censés faciliter l’évaluation de ce positionnement ne sont pas standardisés entre les fabriquants, et le marquage généralement unique par taille de tube ne tient pas compte de la croissance associée à l’âge gestationnel. L’objectif de l’étude est de décrire les distances entre les cordes vocales (CV) et la moitié de la trachée en fonction de l’âge gestationnel et proposer des nouveaux marquages adaptés. Méthodes : la moitié de la longueur de la trachée ajoutée à la hauteur de la lame postérieure du cricoïde permet d’estimer la distance entre les CV et la moitié de la trachée (CV-MiTr). Ces longueurs sont issues à postériori d’une base de données prospective reprenant les distances détaillées du larynx et de la trachée mesurées lors d’autopsies de fœtus et nouveau-nés exempts de malformation des voies respiratoires (Fayoux et coll., Journal of anatomy 2008). Une corrélation est établie avec l’âge gestationnel. Résultats : les données proviennent de 121 patients. Il existe une corrélation linéaire entre la distance CV-MiTr et l’AG (r=0,91; y=2,6043+0,6275x; p<.0001). Des marqueurs d’insertion positionnés à 17,7; 18,9; 20,8; 22,7; 24,6 et 26,4 mm correspondraient à des AG de 24, 26, 29, 32, 35 et 38 semaines respectivement. Ils pourraient être indiqués par des lignes de couleurs contrastées. Conclusion : la relation linéaire entre la distance CV-mi-trachée et l’AG donne l’opportunité de revoir les marqueurs d’insertion des tubes endotrachéaux pour les patients les plus petits. Ces nouveaux marqueurs devraient être comparés cliniquement à ceux actuellement en usage avant d’être généralisés. [less ▲]

We describe a cortical desmoid lesion in a 13-year-old male football player. This case is the typical illustration of symptoms and radiological findings founded in cortical desmoid. Cortical desmoid is benign cortical fibro-osseous lesion that most frequently occurs in the medial supracondylar femur. A traumatic pathogenesis of this lesion is the most probable cause due to higher traction forces at the insertion site of gastrocnemius or the aponeurosis of adductor magnus. It’s usually diagnosed in 10-15-year-old male adolescent who present knee pain, tenderness or swelling. It also can be asymptomatic and incidental finding on radiological exam. Radiologic features depend on the shape and the stage of lesion evolution. It is important to make a correct diagnosis to avoid many additional tests and biopsy, thinking it is a malignant bone tumor. Despite no published therapeutic guideline exists in literature, symptomatic treatment can be considered efficient. [less ▲]

Neurinoma are slow growing encapsulated tumors, coming from Schwann cells. They are a rare cause of low back pain, possibly with a radiating pain in the inferior limb. This case report describes the managing of a patient with right cruralgia without strength lost. The CT- scan had failed to highlight a lesion corresponding to the symptoms of the patient. A MRI was therefore realized, and was able to show a lumbar intradural tumor. The MRI signal of neurinoma is usually typical. However, in this case, the histo-pathological analysis has been necessary to confirm the diagnosis. The patient underwent laminectomy and tumor resection with nearly complete resolution of symptoms, excepting a right perineal hemihypoesthesia, probably corresponding to the location of the concerned nervous root. The MRI is the best method to explore cruralgia or a sciatica not responding to treatment, and without precipitating factor such as disc herniation explaining the symptoms. [less ▲]

3D point clouds describe urban shape at different scales, precisions and resolutions depending on the underlying sensors and acquisition methodology. These factors influence the quality of the data, as well as its representativity. In this paper, we propose a multi-scale workflow to obtain a better description of the captured environment through a multi-scale representative point cloud, presenting an unlimited depth and multisensory data fusion. Our method is shown over a ''smart point cloud'' data structure and based on data fusion principles retaining higher description and precision on overlapping areas. The concept is illustrated through a use case on the castle of Jehay (Belgium), where aerial LiDAR data, terrestrial laser scanner point cloud and photogrammetrybased reconstruction are combined to obtain a multi-scale data structure.

The rural poultry in Algeria is a supplier of popular products. The aims of this study are to characterize local chickens in Kabylie in terms of the livestock practices, management, flock structures, uses, performance and phenotypes. The present survey addresses this issue in the case of Kabylie, a mountainous coastal region of Algeria, and concerns 28 households raising poultry and a morpho - biometric description of 388 (290 females and 98 males) adult local chickens. The farming practices is characterized by a reduction in the time allocated for this activity and to deal with production costs which are aspects of an unproductive extensive livestock system considered as a secondary activity. The body weight is 2.03 ± 0.22 kg and 1.61 ± 0.19 kg respectively in the male and the female. The age at first egg, egg weight, egg production per hen per clutch, number of clutches per year, hatchability and number of chicks weaned are 28.00 ± 3.82 weeks, 49.03 ± 3.66 g, 13.57 ± 1.64, 3.82 ± 1.14, 89.29 ± 9.79% and 7.82 ±1.75 respectively. The comb type is mostly single (89.43%). Skin colours are principally white (39.18%) and yellow (39.43). The comb and wattles are mostly red (93.30). Shanks colours are principally yellow (49.74%) and white (24.23%). The most common plumage colours are salmon (14.43%), white (12.11%), black (17%), grey (9.54%) and gold (9.02%). The genetic improvement of local poultry breeds is also to consider, provided that the suitability of the animal with respect to the context of its breeding is preserved. [less ▲]

Despite increasing use of ANPR cameratechnology, especially in criminal investigations, literature and the experience of the police with whom we worked, seem to show that there is no systematic method to locate as adequately as possible these expensive facilities. Given a set of four categories of robberiesover one year localized within the province of Liège (Belgium), we propose a methodology based on a multi-criteria analysis, making use of density offenses, road density and the distance between the sites of the cameras. Multi-criteria approach can adjust the factorweightings for different types of offenses. In addition, the methodology is iterative, insofar cameras sites are located in successive phases. One result validation criteria is provided in the form of a territorial coverage rate considering the number of selected camera sites and the travel time from each of these sites. [less ▲]

This paper addresses the problem of efficiently operating the storage devices in an electricity microgrid featuring photovoltaic (PV) panels with both short- and long-term storage capacities. The problem of optimally activating the storage devices is formulated as a sequential decision making problem under uncertainty where, at every time-step, the uncertainty comes from the lack of knowledge about future electricity consumption and weather dependent PV production. This paper proposes to address this problem using deep reinforcement learning. To this purpose, a specific deep learning architecture has been designed in order to extract knowledge from past consumption and production time series as well as any available forecasts. The approach is empirically illustrated in the case of a residential customer located in Belgium. [less ▲]

We study the problem of predicting Internet path changes and path performance using traceroute and machine-learning techniques. Path changes are frequently linked to path inflation and performance degradation. Therefore, predicting their occurrence could improve the analysis of path dynamics using traceroute. By relying on neural networks and using empirical distribution based input features, we show that we are able to predict (i) the remaining life time of a path before it actually changes, and (ii) the number of path changes in a certain time slot with relatively high accuracy. We also show that it is possible to predict path performance in terms of latency, opening the door to novel, machine-learning-based approaches for RTT prediction. [less ▲]

In these times of global change, understanding how carbon flows through ecosystems is of primary importance. In coastal Mediterranean regions, Posidonia oceanica meadows produce and store a lot of carbon, but most of it is described as refractory. As a step in the understanding of how organic matter degradation/storage happens in this ecosystem, this study focus on small scale relationships between the microbenthic loop (organic matter, microphytobenthos, bacteria and meiofauna) and environmental parameters (grain size, P. oceanica density, vegetal fibre biomass, pore water nutrient content, sediment total carbon (TC), organic carbon (TOC), nitrogen (TN) and phosphorous (TP) contents, phaeopigments and bacterial production (FDC)). Thus, a 1.25 m x 1.25 m frame was put in a pristine P. oceanica meadow and twelve points were randomly sampled in May 2008 for all the studied parameters. At such a small scale, every component of the microbenthic loop presented a heterogeneity, which was the highest for the microphytobenthos biomass and the lowest for total meiofauna abundance (TMA). No relationship was found between the components of the microbenthic loop but the abundances of Turbellaria and Ciliophora were correlated with total organic matter in the sediment (TOM). None of the environmental parameter was linked with the microphytobenthos biomass, suggesting that the high spatial variability observed did not depend on the measured parameters. Relationships were found between TOM and ammonium, total bacteria abundance and biomass (TBA and TBB) and sediment phaeopigments, TMA and TC, TN and TP. TBB variability was however explained by a combination of FDC and nutrient contents in pore water and sediment. Taking the microbenthic loop as a whole, pore water ammonium and nitrites + nitrates, FDC and phaeopigments were able to explain the observed variability. So, at small scale the variability in the microbenthic loop of a P. oceanica meadow is related with parameters linked with degradation processes and bacteria activities (phaeopigments, FDC, ammonium, nitrites + nitrates), except for meiofauna, which is related with the nutrient content of the sediment, especially TC. Those results underline the importance of the relationship between the microbenthic loop and degradation processes, even at a small scale. [less ▲]

It has recently become possible to monitor patients’ voices outside the speech therapist’s office with a portable, easy-to-use tool: the voice dosimeter. This tool measures voice frequency and sound pressure level, as well as the duration of phonation, during a full day of regular activities. In addition to voice accumulation in an ecological context, the dosimeter used in this study (VoxLog, Sonvox) gives patients feedback on their voice use. In practice, the clinician configures the device so that it provides a vibratory signal in real time when the patient speaks above or below a predetermined frequency or sound pressure threshold. The feedback is intended to make patients aware of inappropriate vocal behavior and encourage them to change it. In this case study, we used biofeedback with the aim of reducing sound pressure level for a teacher suffering from vocal fold nodules. Our goal was to determine whether vibrotactile biofeedback applied in an ecological context for three consecutive weeks could reduce excess sound pressure. The feedback was activated every time the teacher spoke too loudly; its purpose was to help her avoid vocal abuse and (re)learn healthy vocal behaviors. This preliminary study generated encouraging results regarding the use of biofeedback in voice treatment. Nevertheless, it is important to investigate how this tool can best be implemented for patient management in speech language pathology. In addition, the method should be validated with randomized studies using a larger sample. [less ▲]

Estimating the stationary background of a video sequence is useful in many applications like surveillance, segmentation, compression, inpainting, privacy protection, and computational photography. To perform this task, we introduce the LaBGen-P method based on the principles of LaBGen and the conclusions drawn in the corresponding paper. It combines a pixel-wise median filter and a pixel selection mechanism based on a motion detection performed by the frame difference algorithm. By working with pixels instead of patches, as originally done in LaBGen, it avoids some discontinuities between different spatial areas and generates better visual results. In this paper, we describe the LaBGen-P method, study its performance on the sequences of the SBMnet dataset, and compare it to that of LaBGen and other methods on the same dataset. Both algorithms emerged as the best ones during the IEEE Scene Background Modeling Contest (SBMC) organized in 2016. However, as there is not yet a good understanding of the recommended metrics, and due to the small amount of video sequences provided with the corresponding ground truth, we have performed a subjective evaluation. More precisely, 35 human experts were asked to compare background images estimated by LaBGen-P and LaBGen, and select the best one. From these experiments, it turns out that the results of LaBGen-P are preferred for about two thirds of the video sequences. Note that we provide an open-source C++ implementation at http://www.telecom.ulg.ac.be/labgen. [less ▲]

Fiber reinforced polymer (FRP) reinforcement in deep beams has been proposed as an alternative to steel reinforcement to increase the durability of members in corrosive environments. Since FRP reinforcement has lower stiffness than steel reinforcement and typically exhibits higher tensile strength, there is a need for new models capable of capturing the effect of these properties on the shear strength of deep beams. This paper proposes such an approach for members without shear reinforcement, which is an extension of a two-parameter kinematic theory (2PKT) for steel-reinforced deep beams. The original approach is modified to account for the effect of large flexural strains on the shear capacity of the critical loading zones in deep beams where the concrete crushes at failure. It is shown that a simple modification based on test data can result in adequate shear strength predictions. It is also shown that the extended 2PKT captures well the effect of reinforcement stiffness, shear-span-to-depth ratio, and section depth on the shear capacity of deep beams with FRP reinforcement.

The assessment of adaptive facades presents a barrier in light of the fact that there is no settled assessment technique se to systematically reach this goal. Many of the available façade performance evaluation systems or frameworks have restricted applicability for such advanced building facades. The complexity of adaptive or dynamic facades evaluation is related to the performance evaluation of façade elements, systems and overall building performance coupled to occupant behavior and occupant satisfaction. In this context, we present\s a case study for an adaptive sunscreens façade and evaluate its performance and occupant behavior. The evaluation focuses mainly on pre and post construction phase of adaptive facades: The design assist phase (including the durability test, visual mockup, onsite mashrabiya mounting and weather stripping), the commissioning phase (field verification and performance testing) and the monitoring phase. The selected project is a 150 meters high twin tower that stands with honey-comb inspired structure and automated dynamic solar screen that responds to the sun’s movement. These solar screens respond dynamically and automatically to the angle of the sun which improves the control over energy consumption, solar radiation and glare with the ability to admit natural light into the building. The paper is part of the research activities of working group 3 of the European COST Action 1403 on “Adaptive Facades “. Different methods were used for evaluation, this include: interviews with the architect and façade engineer and technical control specialist, occupants, reviews of standard and codes, review of energy models and a systematic design process mapping. A documentation of the case study describing the post construction occupant comfort, and façade operation was prepared. This paper’s audience is mainly project managers, architects, building façade engineers together with facility managers concerned with the process of design, construction and operation of adaptive sunscreens facades. The outcome of this study identifies quantifiable performance indicators and effective strategies for the design and performance evaluation of optimal adaptive facades. [less ▲]

BRAIN-TRAINS is a project supported by the Belgian Federal Government that deals with the possible development of rail freight intermodality in Belgium, approaching this transport issue from an interdisciplinary perspective. Life Cycle Assessment (LCA) methodology is used to analyse the sustainability impact of rail freight intermodality. The rail freight system has been divided in three sub-systems: rail transport operation, rail infrastructure and rail transport equipment (locomotives and wagons). First, a SWOT analysis of the intermodal rail freight transport has been performed to identify internal characteristics and possible external trends of the intermodal rail freight transport. The most important elements identified in the SWOT analysis have been selected through a Delphi-technique with the collaboration of a panel of expert. Thirdly, the selected elements have been translated into clear and measurable parameters, defining for every parameter an input value to quantify the scenarios. The parameters are measured in “tonne-kilometre”. Finally, three divergent Belgian scenarios with a time horizon set in 2030 have been built for further analysis. These scenarios are directly linked to the third strategic goal of the European Commission’s White Paper on transport (2011), which aims to shift the 30% of road freight over 300 km to other modes such as rail transport by 2030. As a result, a best, worst and medium case scenarios have been developed, depending on whether the 30% shift has been successfully accomplished, the status quo has been maintained or the goal has not been completely reached by 2030, respectively. The direct transport emissions and energy consumption during the rail transport activity have been determined using the LCA methodology. These LCA results have been used to improve the accuracy of existing commercial databases as Ecoinvent for the Belgian situation. [less ▲]

Green Building movement has grown in Jordan for the last 10 year for environmental and financial reasons directly related to energy consumption and cost. Despite the few success stories, green design and green buildings are not yet the norm in the building sector in the country. One main concern for design engineers as well as investors and building owners is the extra cost green building will bring compared to traditional one. This assumption is wrong since a building cost should be analyzed through its life cycle, which not only include design and construction but also operation and maintenance costs as well. Since issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, Jordan opened a new era in the RE and EE, a changing point directly related to this law is the ability to sell electricity production to electricity companies and not only being consumers. The building sector is a direct winner if designers and engineers make right decisions. An ambitious but possible goal is to design and build Net Zero Buildings, which are buildings that produce energy as much as they consume. The aim of this paper is to provide real life cost-effective building strategies and design scenarios that will lead to a successful near Zero Energy Building in Jordan. The paper will use a representative residential apartment in the city of Amman (135- 155 m2) as the base case for the study. The design will be upgraded to include main green building strategies recommended for the climatic zone, provide loads for required systems, and test them all against performance and cost. Design scenarios will be tested and refined tell reach the best design formula that will be both functional and cost effective. The paper will provide a list of recommendations for best economically feasible design solutions and system selections that can lead to a near Zero Energy Building in Jordan for residential apartments.

Firstly medical files of horses with moderate or severe MR and/or AR that had a follow-up, were retrospectively reviewed over a 15-years period (2000-2015). Clinical and echocardiographic data of 25 horses with moderate or severe MR (16/25) or AR (8/25) or both (1/25) were considered. All horses had undergone 2 or more echocardiographic exams 6 months to 10 years apart. Eight horses developed CHF (4 MR and 4 AR) and all died/were euthanized. Diastolic left ventricular internal diameter, left atrial diameter and pulmonary artery diameter were/became above reference values in 17/25 horses but no significant difference was observed between the first and the follow-up measurements (Student's t-test, p<0.05). Secondly follow-up data of additional horses with moderate or severe MR was collected by telephone survey. Owners of 27 horses agreed to answer the survey 1 to 6 years after diagnosis. Ten horses with CHF had died, 3/27 had developed CHF, 10/27 had remained clinically stable and 4/27 had died of non-cardiac causes. Results of this study confirm that moderate or severe MR and AR carry a guarded to poor long-term prognosis as 40% (21/52) of the studied horses developed CHF. [less ▲]

Traceroute is the most widely used Internet path analysis tool today to study the topology of the Internet and to diagnose routing failures as well as poor performance events. 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 any given destination back to the source. This is a major drawback for ISPs, who need to understand the performance of the Internet paths connecting popular services (e.g., YouTube and Facebook) to their customers. Even if public servers and distributed measurement platforms can provide partial reverse path visibility through ad-hoc measurements, there is still a need for a structured approach capable of analyzing the performance of Internet paths connecting any pair of nodes (servers, routers, hosts, etc.). While the problem of reverse traceroute has been addressed in the past, proposed techniques rely on IP address spoofing – which might lead to security concerns, and assume the availability of certain route-tracking options –, which might not be available. In this paper, we introduce and evaluate DisNETPerf, a new tool which provides exactly the same type of information as traceroute, but for paths connecting arbitrarily selected nodes. DisNETPerf works by firstly locating probes (i.e., measurement points) that are the closest to a given target node, using them to perform traceroute measurements from the target point-of-view to a given destination for path performance monitoring and troubleshooting purposes. We propose two techniques for probe location, and demonstrate that the reverse path (from server to users) can be measured with very high accuracy in certain scenarios. We also analyze relevant characteristics of Internet paths and distributed measurement platforms, which reinforce the applicability and relevance of DisNETPerf in current Internet. [less ▲]

La faisabilité des tests vibratoires ne peut pas être uniquement évaluée à partir des capacités du pot vibrant. Le couplage entre la structure testée, le vibrateur électrodynamique et le système de contrôle peut induire des comportements inattendus pouvant mettre à mal la bonne mise en oeuvre des essais. Ce travail a pour but de développer un outil de simulation numérique des tests vibratoires sur le moyen d’essai installé dans les locaux de V2i. Le modèle électromécanique ainsi que le recalage à partir de mesures sont décrits dans cet article. L’introduction du modèle de la structure à tester (modèle réduit) et la fermeture de la boucle de contrôle à l’aide du modèle de contrôleur fourni par Siemens LMS sont également abordés. La validation de la méthode est démontrée en confrontantla simulation d’un essai sur une structure industrielle aux résultats expérimentaux obtenus. Les possibilités offertes par le simulateur dans la recherche de solutions lors, par exemple, du contrôle aupassage d’une antirésonance seront brièvement décrites. [less ▲]

Belgium has fifteen structures included in the list of large dams of the International Committee on Large Dams. Six are managed by Engie Company, the other nine are owned by the Walloon regional public authority. The Belgian legislator has never enacted specific rules for large dams. However, managers have always been concerned with this issue. They developed procedures and methods that were subject to exchanges of experience with their counterparts, in particular through the Belgian Committee on Large Dams. In this ongoing research of security, the impact of multiple failure scenarios (dam break, quick emptying …) on the people and the environment downstream of dams is a particular focal point. An impact study has been conducted for the main plants. This study is based on a deterministic numerical method. The methodology, the assumptions regarding the failure mode or emptying and the lessons learned from the analyses are presented. These results are an important step in the assessment and the management of risks. Indeed, regulations were recently enacted for the management and the coordination of any activity likely to seriously impact public safety during crisis periods. These rules apply therefore for large dams. In this context, managers have established an emergency plan for each structure. This paper provides a broad overview on the issues of the evaluation and the management of dysfunction risks of Belgian dams, as well as on approaches and collaborations initiated between the private managers and public authority.

Land-use change models are used to explore the dynamics and drivers of land-use/landcover change and to inform policies affecting such change. A broad array of applications and modeling methods are available and each type has certain advantages and disadvantages depending on the objective of the research. This work presents an approach combining cellular automata (CA) model and supported vector machine (SVM) and binary logistic regression model (Logit) for simulating urban expansion in Wallonia (Belgium). This article emphasizes the interest in comparing combining CA with conventional Logit versus combining CA with SVM method as a base of CA model transition rule. Relative operating characteristic (ROC) and spatial matrices are used to validate the model. Model validation shows that the allocation performance of CA-SVM outperformed CALogit approach. [less ▲]

Nel 2011 l’UNESCO ha adottato la Raccomandazione sul Paesaggio Storico Urbano che mira al riconoscimento e all'identificazione della stratificazione e dell'interconnessione dei valori - naturali e culturali, materiali e immateriali, internazionali e locali – riscontrabili in qualsiasi città storica, concepita come un “patrimonio vivente” delle comunità. In tale visione il patrimonio culturale urbano è un elemento riconosciuto non solo dagli esperti, ma dalle intere società che ne valutano gli elementi identitari mirando a conservarli per le generazioni future. La Raccomandazione, in particolare, sostiene che per l'interpretazione e la conservazione del patrimonio culturale si può beneficiare di metodi di valutazione tradizionali e di metodi innovativi basati su dati geo-localizzati e sui dati digitali dei social media, come tweets geo-localizzati, impronte digitali e foto su Flickr. Il presente contributo illustra una metodologia basata sull’analisi delle immagini su Flickr. Dai risultati ottenuti si è evinto che proprio l’indagine dei social media può contribuire ad una comprensione significativa dei valori culturali del contesto urbano, fornendo così la possibilità di una migliore integrazione dei valori socio-culturali riconosciuti dalla collettività nei processi di conservazione e di pianificazione urbana.

Il presente contributo intende approfondire i caratteri iconografici delle realtà paesaggistiche urbane e naturali rappresentate nei disegni di alcune personalità della cultura belga di fine Ottocento. In particolare le immagini presenti nei tre volumi di Emile Bruylant, (La Belgique illustrée, editi nel 1892) – hanno registrato quei caratteri urbani e naturali che il Belgio vedeva dissolversi in favore di un preteso sviluppo politico ed economico del periodo di Leopoldo II. Nell’ultimo decennio del XIX secolo una grande opera di sensibilizzazione nei confronti della tutela del paesaggio belga urbano e naturale fu portata avanti in Belgio da numerosi artisti, i quali furono tra i primi a nutrire spiccata sensibilità verso i temi della conservazione e delle testimonianze storiche. Il contributo intende dunque analizzare il legame tra le immagini riportate nei volumi e lo sviluppo di talune posizioni conservative che nell’ambito belga è possibile riscontrare in alcune figure, tra cui quella di Charles Buls) e nell’ azione della Société Nationale pour la protection des sites et des monuments.
