We propose a new method for automatic 3D multimodal registration based on anatomical landmark detection. Landmark detectors are learned independantly in the two imaging modalities using Extremely Randomized Trees and multi-resolution voxel windows. A least-squares fitting algorithm is then used for rigid registration based on the landmark positions as predicted by these detectors in the two imaging modalities. Experiments are carried out with this method on a dataset of pelvis CT and CBCT scans related to 45 patients. On this dataset, our fully automatic approach yields results very competitive with respect to a manually assisted state-of-the-art rigid registration algorithm. [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, I study the workers’ speeches (“Reden and Rufe”) in the 19th-Dynasty tombs of Deir el-Medina and its surroundings. For this period, only three tombs in Deir el-Medina (TT 212, TT 217, and TT 266) and one in the Theban necropolis (TT 16) preserve such texts. The goal of this paper is twofold. First, it aims at showing that, after falling into disuse in elite tombs, workers’ speeches appear in the tombs of craftsmen and the upper middle class, further evidence of the “democratisation” phenomenon during the 19th Dynasty. A wall relief fragment of the craftsman Meryptah from Saqqara (18th-19th Dynasty) indicates that this phenomenon was not restricted to the Theban area. The second goal of this paper is to determine what kind of language is used in 19th-Dynasty workers’ speeches, since this literary genre is sometimes thought to be written in the vernacular. I argue that it is a mimetic language, “à-la-manière-de,” more than an actual colloquial language. Regarding this question, the tombs of Ipuy (TT 217) and Amennakht (TT 266) lead to a dead-end because of their fragmentary state. The tomb of Ramose (TT 212) and the tomb of Panehsy and his wife Tarenu (TT 16), on the other hand, reveal Late Egyptian linguistic features. But, because their owners belong to a lower social class than the elite, it might suggest a reinterpretation of the rules specific to the literary genre of the workers’speeches (possible diastratic/diaphasic variation).

Figure emblématique de la Renaissance rouennaise et normande, Georges Ier d’Amboise rassemble une bibliothèque exceptionnelle, notamment constituée de manuscrits ayant appartenu aux rois aragonais de Naples. Le cardinal s’intéresse également à l’architecture, comme peu de ses contemporains, privilégiant les formes et les fonctions nouvelles, spécialement celles en vigueur en Italie. Il participe aussi à la fortune française d’artistes italiens de renom, comme Andrea Mantegna, Léonard de Vinci, Pérugin ou Andrea Solario, dont il commande ou acquiert des œuvres afin de décorer ses demeures, le château de Gaillon en tête. Mais, alors que son rôle dans la diffusion, au nord des Alpes, des idées et des motifs venus d’Italie est indéniable, le portrait de Georges Ier d’Amboise amateur d’art comprend bien d’autres facettes. Prolongeant une recherche entamée à l’occasion de la parution de l’ouvrage Georges Ier d’Amboise 1460-1510. Une figure plurielle de la Renaissance (2013), cette contribution entend s'arrêter sur les objets et les œuvres d’art que l’on peut associer au mécénat et/ou aux possessions de l’archevêque de Rouen. Nous nous pencherons sur les productions italiennes qui sont liées à Georges Ier d’Amboise mais aussi sur les étoffes, les pièces d’orfèvrerie et les tableaux de chevalet, qui sont mentionnés en nombre dans les comptes de dépenses de la construction du château de Gaillon et dans les inventaires qui décrivent les biens meubles conservés dans les demeures du cardinal. L’analyse de ces sources – que jusqu’ici les historiens ont surtout utilisées pour restituer la chronologie du château de Gaillon, rétablir la distribution intérieure de la demeure ou décrire la célèbre bibliothèque du légat alors qu’elles se révèlent extrêmement précieuses pour présenter les collections du conseiller de Louis XII – montre que le goût de Georges Ier d’Amboise, bien que novateur, s’inscrit aussi dans la continuité de celui des amateurs français de la fin du Moyen Âge.

Le projet EpistolART explore le matériau épistolaire dans le but de mieux préciser le statut socio-professionnel des artistes de la Renaissance italienne. Dans ce cadre, le "Carteggio inedito d’artisti dei secoli XIV, XV, XVI" de Johann Wilhelm Gaye (1839-1840) constitue l’un de nos corpus privilégiés. Méritoire le travail de Gaye n’en demeure pas moins dépassé : les transcriptions, souvent partielles et contestables, requièrent une actualisation, suivant les critères de la philologie, de la codicologie et de la paléographie moderne. Cette contribution s'organise autour de trois lettres évoquant Léonard de Vinci, lettres publiées dans les volumes de Gaye et dont les membres du projet EpistolART proposent une nouvelle édition. Elles constituent des documents extrêmement précieux pour écrire l’histoire des relations entre le maître florentin et la France. Si les historiens qui se sont penchés sur la vie et l’œuvre de Léonard de Vinci connaissent ces correspondances, rares sont ceux qui ont recouru aux documents épistolaires originaux. Or, ce n’est qu’au départ d’un texte sûr, appréhendé tant dans sa matérialité que dans ses contenus, que peuvent se déployer des analyses scientifiquement fondées. [less ▲]

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 ▲]

Depuis 1953, les Musées royaux d’Art et d’Histoire possèdent quatre tapisseries, illustrant autrefois une Histoire d’Hercule, tissées durant la seconde moitié du XVIe siècle dans l'atelier bruxellois de Frans Schavaert. La découverte de quatre autres pièces, dispersées dans diverses collections privées, a permis à quelques spécialistes de reconsidérer la tenture dans son ensemble. L’objectif de cette communication est de réexaminer cette suite, encore trop souvent méconnue des chercheurs, qui constitue un bel exemple, toujours conservé en Belgique, du style Renaissance dans l’art de la tapisserie bruxelloise. Cette intervention consiste à revoir les aspects iconographique et stylistique de la tenture, à retracer la date du tissage, particulièrement à l’aide des bordures, et à fournir de nouvelles données sur l’œuvre du licier [less ▲]

Originaire d’Asie Mineure, Irénée est un témoin de la situation de plurilinguisme dans l’Imperium Romanum du IIe s. apr. J.-C. Comme beaucoup de ses contemporains, il est venu à Rome, ville cosmopolite au centre de l’Empire. Plutôt que de retourner dans sa patrie natale, il a poursuivi sa route vers l’Occident pour se fixer en Gaule, à Lyon, dont il deviendra évêque. Irénée a donc connu plusieurs situations linguistiques. Il se meut d’abord au sein de l’Empire romain, où deux langues coexistent, le latin et le grec, qui atteignent, durant le IIe s., un point d’équilibre, dont témoignent certaines œuvres, comme les Nuits Attiques d’Aulu-Gelle. Ensuite, l’Asie Mineure, d’où est parti Irénée, se caractérise par une grande diversité linguistique et par une survivance des parlers locaux. Le christianisme s’est appuyé sur ces langues locales, persistantes dans les campagnes, tandis que les villes, hellénisées, restaient des foyers du paganisme. Enfin, en Gaule, la question est de savoir dans quelle mesure la langue des Gaulois a persisté et a pu être connue d’Irénée. A ce sujet, un passage de la préface de l’Adversus haereses (Οὐκ ἐπιτητήεις δὲ παρ᾿ἡμῶν, τῶν ἐν Κελτοῖς διατριβόντων καὶ περὶ βάρβαρον διάλεκτον τὸ πλεῖστον ἀσχολουμένων… « Tu n’exigeras de nous, qui vivons chez les Celtes et qui, la plupart du temps, traitons nos affaires en dialecte barbare… ») mérite d’être analysé.

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 ▲]

Several energy efficiency concepts and comfort models emerged in the last 15 years seeking high performance buildings and optimal occupant comfort conditions. The aim of high performance buildings is to reduce the carbon footprint and energy consumption of buildings while maintain a fit to purpose comfort. In this context, this work raises the question of fir to purpose comfort models that can from one side reduce the energy consumption of typical office buildings in hot climates (cooling dominated) while on the other side ensuring indoor thermal comfort. Indeed, studies that address energy efficiency are many, however it is in most cases applied to temperate or cold climates and barely explored for hot climates. The objective of this paper is to (1) combine several comfort models for a net zero energy building in hot climates, (2) select the comfort model that shows the optimal comfort quality of indoor environment and (3) compare the building's annual energy consumption for each used comfort model. To respond to our research problems, a methodology has been established, which goes through several phases. First identifying the different comfort models comfortable to use in hot climates (ISO 7730 / EN 15251 / adaptive ASHRAE / Givoni), secondly selecting a typical validated office building model as a reference building and finally selecting representative cities in the Mediterranean arid and hot climate (Algiers / Sicily / Cairo / Dubai). The study used building performance simulation to generate the different results on the energy consumption and the operative temperatures of the different models of comfort in each city. The paper ultimately identifies the fit to purpose comfort models for a medium size net zero energy office building in hot climates. The paper presents a comparison that can help building professional to identify the most appropriate comfort model that allows optimizing energy consumption, ensuring thermal comfort for robust perfromnce of net zero energy buildings in hot climates.

The use of foraminifers as bioindicators of pollution in coastal and paralic environments has undergone a very fast development. Among various criteria, morphological anomalies are sometimes considered as pollution indicators. This paper presents a synthesis of the studies correlating foraminiferal assemblages and environmental concerns. Sediment cores retrieved along the northern coast of Sfax (Tunisia) are used to monitor the response of benthic foraminifera to modern pollution and environmental stress. Sediment samples were separated immediately after collection for benthic foraminifera analysis. Binocular microscope and the Scanning Electron Microscope (SEM) were carried out to identify the most significant, normal or deformed, specimens. All observations confirmed that foraminifera may be used as indicators of pollution after deconvoluting from natural impacts. The most sensitive foraminifera identified in the study area are Ammonia tepida, Ammonia beccarii, Elphidium crispum, Peneroplis pertususles Miliolidae, Peneroplis pertusus et Rosalina sp and Peneroplis planatus. The morphological study of benthic foraminifera from surface sediments attests for the pollution of the actual coast. This pollution is recorded in the benthic foraminifera tests mainly as shell deformations, chambers or streaks or abnormal colors. [less ▲]

Bayesian Reinforcement Learning (BRL) agents aim to maximise the expected collected rewards obtained when interacting with an unknown Markov Decision Process (MDP) while using some prior knowledge. State-of-the-art BRL agents rely on frequent updates of the belief on the MDP, as new observations of the environment are made. This offers theoretical guarantees to converge to an optimum, but is computationally intractable, even on small-scale problems. In this paper, we present a method that circumvents this issue by training a parametric policy able to recommend an action directly from raw observations. Artificial Neural Networks (ANNs) are used to represent this policy, and are trained on the trajectories sampled from the prior. The trained model is then used online, and is able to act on the real MDP at a very low computational cost. Our new algorithm shows strong empirical performance, on a wide range of test problems, and is robust to inaccuracies of the prior distribution. [less ▲]

This position paper focuses on the problem of optimizing charging strategies for a fleet of EVs in the context where a significant amount of electricity is generated by (distributed) renewable energy. It exposes how a mobile application may offer an efficient solution for addressing this problem. This app can play two main roles. Firstly, it would incite and help people to play a more active role in the energy sector by allowing photovoltaic (PV) panel owners to sell their electrical production directly to consumers, here the EVs’ agents. Secondly, it would help distribution system operators (DSOs) or transmission system operators (TSOs) to modulate more efficiently the load by allowing them to influence EV charging behaviour in real time. Finally, the present paper advocates for the introduction of a two-sided market-type model between EV drivers and electricity producers. [less ▲]

This paper presents a robust adaptive control methodology based on the concept of second-order sliding modes for satellite formation control in the presence of unknown, but bounded uncertainties. By introducing two sliding variables to achieve the concept of second-order sliding modes, a robust controller is designed so that it forces the first sliding variable to converge to a desired error box in a finite time. Then, the second sliding variable is automatically bounded in a much smaller region by sliding mode control theory, thereby considerably improving the control accuracy. The proposed control scheme is of a smooth form and effectively alleviates chattering. An adaptive law that updates the control gain is also presented without a priori knowledge of the uncertainties. Numerical simulations, in which a desired formation configuration is required to be precisely maintained under uncertain mass and external disturbances, are carried out to validate the efficiency and the accuracy of the proposed robust adaptive control scheme developed herein.

Lack of information is often reported as one of the main study limitations in transport research. Other data sources provide an important opportunity, as the information from these data sources might be fully exploited when they are integrated using an appropriate mathematical framework. This paper determines which data integration techniques can be adopted in the context of road safety, and which criteria should be used to assess the quality of the integrated dataset. The paper contributes to the literature by providing a comparison of different techniques that allow the tabulation of the joint micro-data. To compare the suitability of different Statistical Matching techniques, data from the 2012 Belgium Road Safety Institute (BRSI) Attitude Survey and data from the 2010 Belgian National Household Travel Survey (BELDAM) are integrated. In particular, the socio-economic factor "Income" is being matched to the BRSI Attitude Survey data. The paper discusses and compares different non-parametric micro-objective Statistical Matching techniques, in which the “Income” variable from the BELDAM survey was added to the BRSI Attitude Survey. Based on similarity/dissimilarity measures, the Rank hot-deck Statistical Matching yielded the best result, which is in line with the existing literature. Moreover, from the results, it can be concluded that statistical data matching is a practically applicable technique, which can help overcome the lack of additional information. Further research should focus on using the integrated datasets with an attempt of expanding the scope of variables, and explicitly testing for omitted variable bias. [less ▲]

One of the major challenges in nonlinear system identification is the selection of appropriate mathematical functions to model the observed nonlinearities. In this context, piecewise polynomials, or splines, offer a simple and flexible representation basis requiring limited prior knowledge. The generally-adopted discretization for splines consists in an even distribution of their control points, termed knots. While this may prove successful for simple nonlinearities, a more advanced strategy is needed for nonlinear restoring forces with strong local variations. The present paper specifically introduces a two-step methodology to select automatically the location of the knots. It proposes to derive an initial model, using nonlinear subspace identification, and incorporating cubic spline basis functions with fixed and equally-spaced abscissas. In a second step, the location of the knots is optimized iteratively by minimizing a least-squares cost function. A single-degree-of-freedom system with a discontinuous stiffness characteristic is considered as a case study. [less ▲]

Laser cladding is a metal deposition technique used to fabricate or repair components. In the present work Ti-6Al-4V deposits with a variable thickness are studied to assess the use of laser cladding as a repair technology [1]. Solidification following melting and partial remelting of pre-existing layers is coupled with heat treatment of the solidified material due to the repeated heating and cooling cycles during building. The effect of the building strategy on the metallurgical characteristics of the material for a decreasing track length (DTL) or a constant track length (CTL) strategy is analyzed. Depending on the possible heat accumulation, the nature of the phases are determined by metallography and hardness maps of the deposits. Optical Microscopy (OM), Stereo Microscopy (SM), and Scanning Electron Microscopy (SEM) were used in order to study the microstructure. The generation of the microstructure results from the material thermal history. This one is computed by Finite Element Method and a careful analysis establishes the link between the phase state and the detailed thermal history. [less ▲]

Introduction Since decades in Wallonia (French speaking part of Belgium), athletics competitions for children are miniaturized versions of adults’ competitions. Despite the fact that it has been pointed out that such kind of approach, based on performance, is not appropriated for motor learning and could result in an increased rate of dropout (1), no change has occurred since years. The International Association of Athletic Federation has developed and promoted a more appropriate model of competition for children under 10 years old: ‘Kids’Athletics’ (KA)(2). While this model is well known, it has not been selected by the Wallonian federation as the gold standard yet . This study aimed to analyze the perceived interest of a group of experts about KA, and to identify the strategies that could be considered for KA implementation in Wallonia. Methods Semi-structured interviews were conducted with 14 athletics or marketing experts (demographic presentation; knowledge about KA and personal experience with KA ; opinion about KA model in comparison with the traditional one, and ; strategies that could be helpful to implement KA in Wallonia). Results Findings showed that 12 experts knew the KA concept while 9 have experimented it in their own club. None mentioned an official competition between clubs. A list of KA’s advantages and disadvantages has been identified (organization, children needs, and development). All experts considered that KA was more adapted to children than traditional competition. Based on subjects’ proposals, a progressive strategy for KA implementation is suggested. It includes the support of the federation and recommends to start with the more convinced clubs. Conclusion This study confirms that KA should be implemented in Wallonia. In order to optimize the chances of success, it would be appropriate to multiply actions, taking into account the potential barriers identified by the experts.

Jointed interfaces are sources of the greatest amount of uncertainty in the dynamics of a structural assembly. In practice, jointed connections introduce nonlinearity into a system, which is often manifested as a softening response in frequency response, exhibiting amplitude dependent damping and stiffness. Additionally, standard joints are highly susceptible to unrepeatability and variability that make meaningful prediction of the performance of a system prohibitively difficult. This high degree of uncertainty in joint structure predictions is partly due to the physical design of the interface. This paper experimentally assesses the influence of the interface geometry on both the nonlinear and uncertain aspects of jointed connections. The considered structure is the Brake-Reuß beam, which possesses a lap joint with three bolted connections, and can exhibit several different interface configurations. Five configurations with different contact areas are tested, identified, and compared, namely joints with complete contact in the interface, contact only under the pressure cones, contact under an area twice that of the pressure cones, contact only away from the pressure cones and Hertzian contact. The contact only under the pressure cone and Hertzian contact are found to behave linearly in the range of excitation used in this work. The contact area twice that of the pressure cone behaves between the complete contact and contact only under the pressure cone cases. [less ▲]

Since the 1960’s and the foundation of ICOMOS, charters have been considered as a sort of conservation gospel. In this presentation, we would like to question this fact, in the light of the very particular production and reception conditions of the documents. What may be perceived as a mostly provocative approach seems to us a constructive basis for future reflections. When we read and use charters – in this presentation, we will mainly focus on the Venice Charter, the Nara document and the Riga Charter – , we forget too often that they have been written by human beings, sometimes very tired, in a hurry, and even arguing with each other. The study of the archival material related to the writing of the Venice Charter and the Nara document very clearly illustrates that these documents are rather a conceptual “bricolage” than indisputable normative texts as if they had been written by lawyers. In the case of the Venice Charter, the archive as well as the records of Raymond M. Lemaire, Paul Philippot or Gertrud Tripp make clear that the document has been written at the last moment and adopted too rapidly by an assembly too glad to finally have a updated version of the Athens charter. As a consequence, only a few years later, Raymond Lemaire and Piero Gazzola already questioned the validity of the new text in the light of the extension of heritage debates to the city centers. On the other hand, the fact that a French and an English version of the Nara document were written in parallel by Raymond M. Lemaire and Herb Stovel in 1994 has had immediate consequences on the content and the formulation of the text, which logically left both of them unsatisfied with the result. Even so, the Venice charter and the Nara document still have force of law today. Yet, besides the particular circumstances of their writing, we must keep in mind that these texts answered specific questions, closely linked to the context: a critical answer to postwar reconstruction for the first, and apparently opposed visions of authenticity between East and West for the second. As far as the Riga charter is concerned, the influence of the delicate context of the Eastern bloc collapse is evident. For this reason, using such documents today requires at least a critical reading, going back to the spirit beyond the text. Our presentation will illustrate ad absurdum, through recent case studies, how a cynical reading of such documents can lead to interventions dangerously in conflict with this spirit and the fundamental ideals of conservation philosophy. In the era of late capitalism and heritage globalization, are we allowed to forget the conditions and the context in which our doctrinal documents have been written to justify anything and everything and to meet, for example, the “tourist gaze”, the “nouveaux riches” taste or the architect’s egomania? Do architects really want to know what the writers of the Venice charter’s article 9 meant by the “contemporary stamp”? What are the limits of the tolerance towards reconstruction first expressed by the Nara document, and a few years later, the charter of Riga? So many questions that ICOMOS must face if it wants to pursue its guiding mission in a mostly financial world. [less ▲]

Respectively elected first President and first Secretary General during the first general assembly of ICOMOS in Cracow in 1965, Piero Gazzola and Raymond M. Lemaire have deeply contributed to the success of the newly born organisation. During the first years, they didn’t only provoke the creation of numerous national committees around the world, but they also positioned ICOMOS as a major actor of the international conservation scene, through the organisation of conferences and an active participation in the debates initiated by Unesco and the Council of Europe, for which ICOMOS acted as a consultant. The study of Raymond M. Lemaire’s archive, kept at the KU Leuven in Belgium, clearly shows that one of the major concerns of both Lemaire and Gazzola, who had been, in 1964, amongst the main authors of the Venice Charter, was to broaden the scope of the document in order to address the issue of pre-industrial city centres, threatened by late reconstruction or development projects mostly promoting functionalist approaches. Depending on the time available, this presentation will address one or various aspects of Lemaire’s and Gazzola’s contribution to the emergence of integrated conservation, consecrated by the European Charter and the Amsterdam Declaration of 1975, that is: the new ideas (social value of heritage for example) developed during the expert meetings organised by the Council of Europe in 1965-1968, where they both represented ICOMOS. These ideas are synthesised in the report “Saving the face of Europe” in 1973, the relation between these theoretical contributions and Lemaire and Gazzola’s contemporary field experience, the role of Eastern Europe experiences (D. Libal in Prague and M. Horler in Budapest) in the development of an appropriate methodology to address urban issues, the differences between the concept of “integral planning” proposed by Lemaire in 1973 and the “integrated conservation” that was promoted by the 1975 Council of Europe charters, an epilogue could mention the revision projects of the Venice Charter between 1975 and 1981. Based on my PhD about R.M. Lemaire, recently presented at the KU Leuven (Belgium), this presentation aims at clarifying and illustrating the shift from monument restoration towards city “reanimation” or “rehabilitation” during the late sixties and seventies, as well as paying tribute to the action of two of the most important figures of the beginnings of ICOMOS.

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.

Les Trois-Evêchés ont été un terrain fertile pour les congrégations féminines aux 16e-18e siècles puisqu'ils ont vu la naissance de projets religieux conjuguée à une installation massive de « nouveaux ordres » nés ou réformés dans le sillage du concile de Trente. Fondées en Italie au début du 17e siècle, les annonciades célestes se sont implantées majoritairement sur la « dorsale catholique ». Au cœur de ce territoire de frontières, les Trois-Évêchés occupent une position géographique, politique et religieuse incontournable. Dans le cadre de cette journée d’études, il s’agira d’interroger les spécificités éventuelles des cinq monastères que les annonciades célestes firent édifier dans les Trois-Évêchés en les comparant à l’ensemble de la production architecturale de l’ordre en Europe aux 17e et 18e siècles.

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 ▲]

Shallow reservoirs are often used as sediment traps or storage basins, in which sedimentation depends on the flow pattern. Short rectangular reservoirs reveal a straight jet from inlet to outlet with identical recirculation zones on both sides. In longer reservoirs, the main jet reattaches to the side of the reservoir leading to small and large recirculation zones. Previous studies have found an empirical geometric relation describing the switch between these two flow patterns. In this study, we demonstrate, with a simple analytical model, that this switch coincides with a maximization of energy dissipation in the shear layer between the main jet and recirculation zones: Short reservoirs dissipate more energy when the flow pattern is symmetric, while longer reservoirs dissipate more energy with an asymmetric pattern. This approach enables the prediction of the flow patterns without detailed knowledge of small scale processes, potentially useful in the early phase of reservoir design. [less ▲]

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 ▲]

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.

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 ▲]

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 ▲]

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 ▲]

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 ▲]

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 ▲]

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 ▲]

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 ▲]

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 ▲]

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.

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.

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.
