Parmi ses multiples dispositions tendant à canaliser une France perçue comme expansionniste, le congrès de Vienne a entériné la naissance d’un Royaume uni des Pays-Bas, amalgamant des territoires aujourd’hui répartis entre la Belgique, le Luxembourg et les actuels Pays-Bas. Qu’on y voie une barrière contre la France, une sentinelle plantée au nord ou un boulevard pour l’Europe, les Low countries ont un rôle stratégique majeur. Mais la logique militaire ne peut faire abstraction des hommes et les réalités politiques, religieuses, linguistiques conduiront, en 1830, à la fin d’une expérience que peu de diplomates considéraient d’ailleurs, dès ses prémisses, comme viable. Dans cette contribution, nous entendons faire le point sur la période post-française dans l’actuelle Belgique. En quoi les années 1814-1830 ont-elles été une étape cruciale dans l’affirmation d’une identité nationale ou d’un patriotisme belge ? Pourquoi la politique de Guillaume Ier s’est-elle heurtée, dans les provinces méridionales, à une opposition plurielle et parfois paradoxale ? Pourquoi peut-on dire que les questions de liberté d’enseignement, de liberté religieuse et de liberté linguistique se sont intimement liées pour constituer la matrice des événements de 1830, une matrice alimentée bien sûr également par des revendications de nature économique ?

Nell'anno 1525, in particolare negli ultimi mesi della sua presidenza in Romagna, Francesco Guicciardini si dedica ad un’intensa attività epistolare, nonché alla redazione di alcuni discorsi politici. Tali testi presentano, tanto sul piano della forma quanto su quello dei contenuti, similitudini salienti. È tuttavia da escludere che i discorsi fossero destinati dall’autore ad una qualunque circolazione; piuttosto, essi servirono allo storico per riflettere e “fermare il punto” su situazione particolarmente difficile, nella quale doveva dimenarsi come presidente di un’importante regione e in preparazione degli eventi bellici che avrebbero fatto seguito di lì a poco. Le lettere corrispondenti a questo periodo sono invece i documenti che hanno realmente circolato e che potremmo perciò definire «pubblici». Proprio il riscontro di questi due generi di scritture diverse, praticate in uno stesso torno d’anni, e centrate sulle stesse problematiche, permette di mostrare, attraverso l’analisi di un caso specifico, che la tradizionale distinzione tra pubblico e privato è inoperante per descrivere i testi di Francesco Guicciardini e che, ad ogni modo, le categorie attuali non sono applicabili senza discrimine ad un’epoca ricca e complessa come quella della prima Modernità.

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).

This paper develops an in-situ methodology to help architects insure better inclusion of people with Down syndrome all along preliminary phases of the architectural design process, and eventually to the designed space. This methodology first offers architects some design keys in regard of how people with Down syndrome interact with two types of spaces: their personal dwellings and some completely unknown spaces. The methodology then unfolds towards more pro-active inclusion of the participants thanks to playful expression of their feelings and perceptions. This paper discusses how this methodology relates to inclusive and universal design principles as well as prevalent models of disability in architecture. [less ▲]

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.

A small number of autographs are attested among the Greek literary papyri dating from the IV/III centuries BC to the VI/VII centuries AD. They can be found in the form of papyrus rolls, papyrus slips, papyrus or parchment codices or even wooden tablets. According to research by A. Petrucci and T. Dorandi, evidence from the material and the format of the piece, from the layout of the text and its writing, from the state of the text and from the literary genre allow for the identification of autographs. The present paper will briefly review the about 50 Greek literary papyri considered to be autographs. Special attention will be paid to a recently edited II-century medical papyrus (P.Oxy. 74.4970), which seems to present the characteristics of an autograph. [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 ▲]

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 ▲]

Contrairement à la seconde reconstruction qui reste aujourd’hui largement inexplorée, la première reconstruction en Belgique a fait l’objet de nombreuses recherches et publications. Et pourtant, une figure essentielle n’a que très peu retenu l’attention des chercheurs : le chanoine Raymond A.G. Lemaire. Professeur d’archéologie et de restauration à l’université de Louvain, chantre du néogothique dans le sillage de Joris Helleputte, il participe activement aux débats de la reconstruction, non seulement à Louvain, où il est membre de la Commissie voor Stedenschoon, mais dans tout le pays, en tant que membre correspondant de la Commission royale des monuments et des sites et conseiller de l’archevêché de Malines. Auteur de nombreux articles, il synthétise les débats dans “La restauration des monuments anciens”, publiée à Anvers en 1938, tout en développant une approche personnelle se nourrissant de la théorie des valeurs d’Aloïs Riegl et s’approchant de la théorie du “cas par cas” développée à la même époque, en Italie, par Ambroggio Annoni. Bien que les rapports entre les deux hommes ne soient pas documentés dans les archives belges, les nombreux parallèles entre leurs approches, ainsi que le fait que le chanoine Lemaire enverra son neveu, Raymond M. Lemaire, se former chez Annoni en 1943, laissent entendre qu’ils devaient exister. A travers notre participation à la conférence, nous espérons découvrir des éléments susceptibles d’alimenter la poursuite des recherches en ce sens. [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 ▲]

This paper presents a novel approach, which identifies a buffer zone around a given study system and replaces the external system with an equivalent. The aim is to obtain a reduced system, which is suitable for assessment of long-term voltage and frequency dynamics in the study system. First, the proposed methodology ensures that all components, which are impacting the voltage profile of the study system, are included in the buffer zone. For that purpose, the propagation of reactive power changes from the boundary of the study system into the external system are used in a modified depth-first search algorithm to identify the buffer zone. Second, the external system is replaced with equivalents accounting for inertia and primary frequency control effects. The proposed method was successfully tested on a modified version of the ENTSO-E Dynamic Study Model. [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 ▲]

Current codes and standards for fire design of structures in the United States are mainly based on design at the component level using prescriptive approaches, while performance-based design for fire can be used to address the needs for designing modern buildings with cost-effective solutions. Previous research shows that, when system-level performance is considered, fire protection on secondary beam elements in composite steel-concrete floor systems is not necessary due to the development of a membrane action in the concrete slab during fire. This study compares the fire design of a 9-story office building using prescriptive and performance-based designs. The safety levels of the two designs are investigated and compared. It is shown that performance-based design can be used to achieve the required level of safety currently enforced in the U.S. prescriptive guidelines, while providing an opportunity for cost reduction in fire protection material.

The goal of this paper is to identify the respective influence of different characteristics of urban patterns on urban flooding. A set of 2,290 alternate urban patterns was generated randomly using an urban generator tool providing the geometry of buildings and their relative location to the ground, over a square area of 1 km². Steady 2-D hydraulic computations were performed for these 2,290 different urban patterns with identical hydraulic boundary conditions. The computational time was reduced by using an anisotropic porosity model. This model uses relatively coarse computational cells; but preserves information from the detailed topographic data through the use of porosity parameters. Based on the computed maps of waterdepths for the 2,290 urban patterns, a sensitivity analysis based on a multiple linear regression was performed to outline the most influential urban characteristics.

In this paper, we review past (including very recent) research considerations in using reinforcement learning (RL) to solve electric power system decision and control problems. The RL considerations are reviewed in terms of speci c electric power system problems, type of control and RL method used. We also provide observations about past considerations based on a comprehensive review of available publications. The review reveals the RL is considered as viable solutions to many decision and control problems across di erent time scales and electric power system states. Furthermore, we analyse the perspectives of RL approaches in light of the emergence of new-generation, communications, and instrumentation technologies currently in use, or available for future use, in power systems. The perspectives are also analysed in terms of recent breakthroughs in RL algorithms (Safe RL, Deep RL and path integral control for RL) and other, not previously considered, problems for RL considerations (most notably restorative, emergency controls together with so-called system integrity protection schemes, fusion with existing robust controls, and combining preventive and emergency control).

Recent efforts aim at assessing the fire performance of structures in a probabilistic framework. But there is still no well-established method to quantify the reliability of entire buildings. Previous works focused on isolated structural members, therefore not allowing for a determination of the global safety level of buildings. Here, a new methodology is developed to quantify the reliability of buildings in fire. The methodology uses Monte Carlo simulations for constructing fragility functions associated with different fire breakout locations in a building, then combines the functions to characterize the overall building conditional probability of failure, and finally incorporates the probabilistic models for intensity measure and fire occurrence likelihood. The methodology is applied to multi-story steel buildings. This work addresses fire reliability at the building scale, and therefore is useful for standardizing safety level as well as for evaluating community resilience. [less ▲]

In building renovation, the real behaviour of reinforced concrete slabs cannot always be explained by the bending theory according to classical structural mechanics. Indeed, the bearing capacity, as assessed for instance by a loading test, sometimes appears to be much higher than what would be expected. This phenomenon may be caused by the activation of an arch-effect or so-called compressive membrane action (CMA) which can develop even with small vertical deformations. For a slab which is completely restrained, the presence of reinforcement becomes of lesser importance when this phenomenon is activated (except for end fields). Hence, for fire resistance purposes, it can be discussed whether reinforcement and concrete cover has a smaller influence on the bearing capacity for slabs subjected to fire which exhibit a significant concrete compressive membrane behaviour. This paper presents a loading test performed on a real concrete building which highlighted the development of CMA as the load bearing mode. It then proposes a strategy to evaluate the behaviour resulting from the development of CMA in reinforced concrete slabs at ambient and at elevated temperature based on numerical modelling. The numerical analyses are performed with the finite element software SAFIR® using a strip of layered shell elements. A plastic-damage constitutive model with an explicit transient creep formulation is used to capture the concrete behaviour at elevated temperature. [less ▲]

The European Union (EU) is actively encouraging member countries to phase out traditional oil-fuelled cars in cities in favour of Electric Vehicles (EV) as a solution for increasing efficiency, contributing to ensure security of supply, decrease CO2 emission and decrease local (especially urban) air pollution coming from the transport sector. With the increasing associated charging infrastructure deployment all over European countries, the demand coming from these technologies might impact the power system and potentially offer a source of flexibility through variable charging profiles and battery storage capacity options. In the recent years, the Dutch government has adopted several policy support mechanisms for EVs uptake, which made the Netherlands the country with the highest market share of electric cars in 2015 in the EU, and the second-highest share worldwide after Norway. This country is therefore a unique case study for the analysis of EVs charging demand and impact of the power sector. The recent uptake of EVs provides a significant amount of historical data regarding charging profiles, connection times or utilisation patterns pertaining this technology. This paper aims at exploiting such data to evaluate the current and future impact of electric vehicle deployment on the power system. To that end, historical data from 2015 are used in conjunction with the Dispa-SET model, a unit commitment and power dispatch model developed at the Joint Research Centre (JRC) of the European Commission. This aims at investigating the impact of Battery Electric Vehicle (BEV) charging demand on the current Dutch power system, under different hypotheses for BEV technology penetration and renewable energy deployment (i.e. wind and solar) in the country. In addition, looking at the entire connection periods when vehicles are plugged to the grid, the battery capacity connected to the system is estimated, based on commercial BEV battery characteristics. This total capacity is finally used as variable storage unit in the model, in order to investigate the impact that Vehicle to Grid (V2G) strategies could have on the optimal use of power resources available, with particular attention to Variable Renewable Energy (VRE).

Since the early 2000's, the Internet Topology has been frequently described and modeled from the perspective of routers. To this end, alias resolution mechanisms have been developed in order to aggregate all IP interfaces of a router, collected with traceroute, into a single identifier. So far, many active measurement techniques have been considered, often taking advantage of specific features from network protocols. However, a lot of these methods have seen their efficiency decrease over time due to security reinforcements across the Internet. In this paper, we introduce a generic methodology to conduct efficient and scalable alias resolution. It combines the space search reduction of TreeNET (a tool for efficiently discovering subnets) with a fingerprinting process used to assess the feasibility of several state-of-the-art alias resolution methods, using a small, fixed amount of probes. We validate our method along MIDAR on an academic groundtruth and demonstrate that our methodology can achieve similar accuracy while using less probes and discovering subnets in the process. We further evaluate our method with measurements made on PlanetLab towards several distinct ASes of varying sizes and roles in the Internet. The collected data shows that some properties of our fingerprints correlate with each other, hinting some observed profiles could be linked with equipment vendors. Both TreeNET (which implements our methodology) and our dataset are freely available. [less ▲]

It deals with non-clinical concepts that are relevant in General Practice/Family Medicine (GP/FM).

It aims at indexing GP/FM documents such as congress abstracts and theses to get a more comprehensive view about the GP/FM domain. The 182 identified Q-Codes have been very precisely defined by a college of experts (physicians and terminologists) from twelve countries. The result is available on the Health Terminology/Ontology Portal (http://www.hetop.org/Q) and formatted in OWL-2 for further semantic considerations and will be used to index the 2016 WONCA World congress communications.

Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this lecture, we will discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry.

Biomass Combined Heat and Power (CHP) plants connected to district heating networks (DHN) are recognized as a very good opportunity to increase the share of renewable sources into energy systems. However, as CHP plants are not optimized for electricity production, their operation is profitable only if a sufficient heat demand is available throughout the year. On the other hand, these plants often work for baseline operation and back-up boilers are used to supply the peak demand. To extend the use of the CHP plants and reduce costs, conventional fuel use and emissions, it is proposed to study the feasibility of using additional high temperature heat storage as retrofit of an existing CHP plant. This work is based on a simple and effective methodology that provides accurate estimations of economic, environmental and energetic performances of CHP plants connected to district heating networks. The DHN of the University in Liège (Belgium) is used as an application framework to demonstrate the effectiveness of the selected approach. The potential energy and pollutant emissions savings and resulting energy costs are estimated and the current policy limitations will be discussed. [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.

In order to quickly reach incident locations, emergency services have to fairly distribute their resources on the territory. This distribution is based on an analysis which depends on heterogeneous spatial data like past interventions (recurring risk), specific geographical places (sporadic risk), road network or socio-economic variables. On the other hand, Spatial Online Analytical Processing (SOLAP) tools are designed for the collection and the analysis of large spatial data sets. In this study, an original raster SOLAP model is implemented for emergency services of Brussels agglomeration. It allows decision-makers to freely generate risk maps (continuous fields), depending on several dimensions (time, intervention type, risk type, etc.), and to compare them with the accessibility of firefighters and ambulances. Simulations can also be performed on resources locations to see their impact on the main accessibility. [less ▲]

High performance buildings including net zero energy buildings (NZEB) are facing difficulty to become market mainstream in warm and hot climates. Beside the economic there are serious technical and design challenges that hampers design teams design, construct and operate NZEB in mixed and cooling dominated climates. There is a difficulty to make the Passive House standard cross the heating dominated climatic zones in Northern and Central Europe to get implemented in mixed or cooling dominated climates as an ultra-energy efficient building concept. There is a need for setting new climate adaptive energy efficiency target metrics for NZEBs in warm and hot climates. This paper presents guidance and recommendations on the necessary performance target metrics for NZEBs and makes them explicit. Results are based on cross analysis of several case studies, presenting an overview of challenges and providing recommendations based on available empirical evidence to further lower those barriers Worldwide with a focus on the European construction sector. By defining the performance thresholds for NZEBs including the metrics we offer design team the possibility of verification and design assessment during early design decision making phases to instil a kind of practical, evidence based and quantifiable guidance for high performance buildings and in particular NZEBs.

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 ▲]

The emergence of electric vehicles (EVs), combined with the rise of renewable energy production capacities, will strongly impact the way electricity is produced, distributed and consumed in the very near future. 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 ▲]

Aircraft are more than ever pushed to their limits for performance reasons. Consequently, they become increasingly nonlinear and they are more prone to undergo aeroelastic limit cycle oscillations. Structural nonlinearities affect aircraft such as the F-16, which can undergo store-induced limit cycle oscillations (LCOs). Furthermore, transonic buzz can lead to LCOs because of moving shock waves in transonic flight conditions on many aircraft. This study presents a numerical investigation of passive LCO suppression on a typical aeroelastic system with pitch and plunge degrees of freedom and a hardening stiffness nonlinearity. The absorber used is made of a piezoelectric patch glued to the plunge springs and connected to a resistor and an inductance forming a RLC circuit. A mechanical tuned mass damper absorber of similar configuration is also considered. The piezoelectric absorber features significant advantages in terms of size, weight and tuning convenience. The results show that both types of absorber increase the linear flutter speed of the system in a similar fashion but, when optimal, they lead to a sub-critical bifurcation while a super-critical bifurcation was observed without absorber. Finally, it is shown that the addition of a properly tuned nonlinear spring (mechanical absorber) or capacitor (piezo- electric absorber) can restore the super-criticality of the bifurcation. The tuning of the nonlinearity is carried out using numerical continuation. [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 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.

Besides their entertainment value, serious games can have beneficial therapeutic effects for elderly people that improve their health and well-being. Games are likely to be accepted by elderly persons who have enjoyed games their lives, and because there are more and more of such elderly, it is important to investigate games as a therapeutic device. This research reviewed the literature focusing on the effects of games on elderly persons in three main types of effects: physical, cognitive, and social effects. The majority of reviewed papers focused on physical and cognitive effects, and were published in recent years, which emphasizes the relative novelty of this topic and suggests that future research will need to address social impact as well. In addition, while many papers claimed positive impacts as a result of using games, our review found that more attention should be given to research designs. [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 ▲]

A method is presented to model the incompressible, attached, unsteady lift and moment acting on a thin three-dimensional wing in the time domain. The model is based on the combination of Wagner theory and lifting line theory trough the unsteady Kutta-Joukowsky theorem. The result is a set of closed form linear ordinary di erential equations that can be solved analytically or using a Runge-Kutta-Fehlberg algorithm. The method is validated against numerical predictions from an unsteady Vortex Lattice method for rectangular and tapered wings undergoing step or oscillatory changes in plunge or pitch. As the aerodynamic loads are written in state space form in the proposed method, they can be easily included in aeroelastic and flight dynamic calculations. [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 ▲]

Introduction The development of motor skills competencies is critical during childhood should be considered as the central learning outcome in physical education. Assessing motor competencies of the children make sense for teachers, trainers and researchers. The MOBAK-1 testing battery has been recently developed with the aim of assessing a wide panel of motor skills in relationship with locomotion and object-control abilities (1). This battery is complete and easy to use but present a scoring system that is only based on the success or the failure of the task. The aim of the study was to collect descriptive data from Belgian children with MOBAK-1, and to do a critical analysis of the scoring system through the analysis of the failure reasons in the tests. Methods The MOBAK-1 testing battery (1) was addressed to 166 primary school pupils (7.2±0.6 YO) coming from the French speaking part of Belgium. For each test, children received a score from 0 to 2, according to the number of success and fails in the task. Additionally, the evaluator took notes of the failure reasons when it occurs. Results Results from our subjects were in accordance with a previous study (1) for all tests except rolling and jumping tasks. The analysis of the failure reasons revealed that some criteria were too severe as some children failed while they were almost able to do the test correctly. This appeared especially in the rolling and jumping tests where the score did not really reflect the level of the children. Conclusion MOBACK-1 testing battery was successful to assess children motor skills for 6 out of 8 tests. Critical analysis of children failures in the tests revealed that some criteria seemed to be severe. Scoring system should be improved in order to inform about the children level in each test.

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 ▲]

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. En allant plus loin, nous verrons comment les représentations mentales de ces édifices ont participé à la genèse de l’identité de l’ordre, notamment grâce aux sources écrites et iconographiques qui en témoignent.

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 ▲]

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.

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 ▲]
