La tradition liégeoise reste attachée à la personne de l’évêque Étienne (901-920) qui, à l’aube du Xe siècle, montait sur le siège de saint Lambert. Son œuvre a joui d’une renommée certaine au fil des siècles . Elle a connu un grand succès mesurable à l’aune des copies manuscrites dont elle a fait l’objet. On reconnaît désormais à cet évêque un rôle non négligeable dans la diffusion d’un procédé musical mis au point, dans le courant du IXe siècle, dans les abbayes d’Elnone et de Saint-Thierry de Reims. Pourtant, Étienne de Liège n’a, de toute évidence, pas fait école dans la cité mosane . On douta même longtemps de la part qui fut effectivement la sienne dans la composition de ces œuvres. Cet article s'interroge sur les motifs de cette remise en cause des qualités littéraires et musicales du dernier évêque carolingien liégeois. Quelle image ce prélat laissa-t-il à ses ouailles et à ses successeurs ? Quelle influence exerça-t-il réellement sur la production musicale et liturgique ultérieure ? Notger contribua-t-il à la diffusion de son œuvre ? Cet article propose quelques éléments de réponses à la lumière d'une étude de la tradition manuscrite de l'office de la Trinité. [less ▲]

One of the main sources of uncertainty in the asteroseismic models of the Sun and solar-like stars is the poor match between predicted oscillation frequencies and observed ones in the very high frequency domain. Today, effects of turbulence, diffusion, etc., i.e., the so-called "surface effects" are signaled as possible responsible for such a discrepancy. We show that the effect of the stellar deformation due to rotation is of the same order or even larger than these effects. We show that rotation effects, are important for the asteroseismic analysis of the Sun and solar-like stars and they cannot be neglected when modeling such stars. [less ▲]

This paper addresses the problem of online planning in Markov decision processes using a randomized simulator, under a budget constraint. We propose a new algorithm which is based on the construction of a forest of planning trees, where each tree corresponds to a random realization of the stochastic environment. The trees are constructed using a “safe” optimistic planning strategy combining the optimistic principle (in order to explore the most promising part of the search space first) with a safety principle (which guarantees a certain amount of uniform exploration). In the decision-making step of the algorithm, the individual trees are aggregated and an immediate action is recommended. We provide a finite-sample analysis and discuss the trade-off between the principles of optimism and safety. We also report numerical results on a benchmark problem. Our algorithm performs as well as state-of-the-art optimistic planning algorithms, and better than a related algorithm which additionally assumes the knowledge of all transition distributions.

Organic farming is considered to be one of the solutions for the problems of sustainability faced today by the agriculutral sector. This paper describes the growth of the Walloon organic sector during the last years thanks to the support of the regional authorities through financial incentives and a new regional strategic development plan. It also presents some results collected during an on-farm survey concerning organic cereals. It appears that organic farming has significantly developed thaks to public support even if the prices of organic products are exceeding by 30% those of conventional products. Organic farming can play a significant role in the future of Walloon agriculture. However, due to the high conversion rate during these last years, it is not guaranteed that the financial support could be conserved at a such level. [less ▲]

Ce travail s'inscrit dans un cadre géographique regroupant deux pays (RDC et Rwanda) appartenant à la Communauté Économique des Pays des Grands Lacs (CEPGL) avec le Burundi. Le commerce des produits alimentaires entre population transfrontalière est une réalité: Elle est facilitée par un ensemble d'accords et certaines pratiques de proximité qui n'ont jamais été mises en cause, même pendant les périodes des guerres. Les flux importants de produits alimentaires enregistrés lors de la traversée du corridor frontalier entre Bukavu (RDC) et le district de Rusizi (Rwanda), les difficultés et risques auxquels les petits commerçants et les ménages sont soumis, constituent des éléments qui ont guidé le choix de l'approche conceptuelle. Lors de la traversée des frontières, on peut se rendre compte que la ville de Bukavu et le district de Rusizi (Rwanda) ont des fonctions bien réparties. Alors que Bukavu fonctionne comme un grand centre de consommation, le district de Rusizi s'est positionné stratégiquement comme une ville entrepôt (Soule et Musila, 2005). Ces approvisionnements à partir de l'étranger solidifient encore la dépendance alimentaire de la province du Sud-Kivu en général et la ville de Bukavu en particulier. Ce problème mérite une étude particulière et a guidé aussi le choix de ce travail. Le choix de l'approche conceptuelle de cette étude a été aussi motivé par le souci d'étalonner la contribution du commerce frontalier à la paix, à la lutte contre la pauvreté et à la sécurité alimentaire. Ceci constitue des réponses à plusieurs préoccupations de développement et d'intégration régionale. Dans ce cadre, plusieurs auteurs, comme Johnson et al. (2009), Cling (2006), Tegera et al. (2007), Masato Hayashikawa (2009), ont déjà montré qu'il existe un lien entre commerce, développement et lutte contre la pauvreté. Divers programmes sous-régionaux (CEPGL), régionaux (COMESA, CIRGL), internationaux (Banque mondiale) ainsi que diverses ONGs internationales (Alert International, DFID) s'intéressent à cette problématique.

Extreme floods of the river Meuse were simulated based on a detailed 2D unsteady hydraulic model. As part of a coordinated transnational modeling program, the study area considered here extends from Ampsin (Belgium) to the Belgian-Dutch border. The results of the present simulations are passed as upstream boundary condition to a second hydraulic model simulating the same flood scenarios in the Meuse in the Netherlands. In the simulations discussed here for the Belgian part of the Meuse, high accuracy and high resolution data were used to represent the main riverbed and the urbanized floodplains. The operation of all influencing mobile dams was represented in the model. The considered flood scenarios include the 100-year flood in the present situation (Q100), as well as two more extreme floods: Q100 + 15 % and Q100 + 30 %. These values correspond to return periods of the order of, respectively 300 and 1000 years in the present climate; but, according to a transnational climate change scenario in the Meuse basin, they may also be considered as estimates of the 100-year flood in 2050 and 2100. The computations have shown a very limited damping of the flood wave in the study area, not exceeding approximately 1 % of the peak discharge for Q100 and Q100 + 15 %, and reaching about 3 % for Q100 + 30 %. Compared to Q100, increases in the flood levels for Q100 + 15 % and Q100 + 30 % are, respectively, in the ranges 0.5-0.9 m and 1.0-1.8 m. Comparisons with the results from previous steady simulations revealed discrepancies not exceeding 5 cm for Q100 and Q100 + 15 %, and reaching a maximum of approximately 30 cm for Q100 + 30 %. Hence, from the perspective of the variation in peak discharge and flood levels, the study concludes that running the hydraulic model in steady mode is reasonable; although some differences occur in terms of inundation extents. The 2D unsteady model constitutes also a tool of primary interest, which is readily available to design and evaluate protection measures for flood-prone areas such as in the city of Liege. [less ▲]

The Alta Marca Trevigiana (Colli del Piave), between Valdobbiadene and Conegliano, doesn't have a definite recognized identity, despite its strong visual character. However, for the visitor driving along the “Sinistra Piave”, the landscape is seen as a rhythmical composition of invitation to movement at different scales and at various intensity, that can be compared to a musical composition. The question then is how to transform the road from a simple through-way into an occasion to engage with the Colli del Piave, to transform a “landscape scenery” into an “experienced landscape”.

The Thanh Ha district (Haï Duong province, North-Vietnam) has a long history of traditional Thanh Ha Thieu litchis cultivar production. However, the price paid to the farmers for this traditional cultivation has been reducing significantly for more than 10 years. In this communication, recent evolution of Thanh Ha Thieu litchis production and strategies established by producers in order to face the fall in price are studied and a diagnosis of the agricultural extension services involved in Thanh Ha Thieu litchi production is drawn up. Primary data were collected in 2012 through personal interviews and focus groups with multiple stakeholders, authorities and extension organisms and a survey of producers' households made with semi-structured questionnaires. Substantial reduction of litchis production participation in total household incomes was revealed. In parallel, Thieu litchis plantations superficies fall down being converted in favor of new fruit species or in favor of other litchis varieties depending on the production area operating a diversification process. Moreover, progressive abandonment of not converted plantations is marked by plantations cares reduction. In the past five years, all agricultural extension sessions about litchis production have been initiated and organized by the authorities at province and district level collaborating with input supply privat companies. Various inefficiency problems are highlighted such as disequilibrium in training session access, relative trainings uselessness or mismatch between producers' training demand and offer. [less ▲]

Burundi, family agriculture occupies more than 90% of the active population and plays a vital role in food production and participates of more than 50% of GDP. Before the civil war of 1993, Kirundo was deemed "breadbasket of the country" for the simple reason that fed many parts of Burundi in particular food legumes and cereals, so that family farming was oriented the market. Kirundo alone includes 8 lakes with opportunities for field irrigation. Today, this is the first province in Burundi shows a high rate of malnutrition, poverty increased and a sharp decline in agricultural production up more than 500%. In this study, 73 farmers were surveyed in Kirundo, supplemented by secondary data collection. Analysis of data showed us that, despite recurrent droughts in that region which was caused several deaths due to famines and several displacements of people to neighboring countries such as Rwanda and Tanzania, we found 44% of farmers surveyed who had the resilience to climate change. The analysis of data shows that these farmers were members of local development associations, having learned specific topics such as financial management, processing and storage of agricultural products and livestock. That social capital network influences positively their income because they practice not only farming but also revenue-generating activities such as trade and crafts. [less ▲]

In Belgium, Palaeolithic research goes back to the early 19th century, in the wake of mining and quarry work. Geology and paleontology developed early and rapidly and were economically important. As a result, the earliest human history was reconstructed here entirely independently, by defining the Mousterian (Engis, 1830), Aurignacian (Montaigle), Gravettian (Trou Magrite) and Magdalenian (Chaleux) periods. Belgium, due to its central position, is in addition particularly representative of the wave of "modernity" that suddenly was adopted across northwest Europe, overlying a highly diverse and innovative cultural base during the time of the Neandertals. At this point in time, as in others, Belgium played the role of intermediary and incubator between the British Isles and the Rhineland, extending as far as the Loire. [less ▲]

The Taoussa Project is a component of a large development scheme of the Niger River in the north-eastern part of Mali aiming at reducing desertification and improving socio-economic activity. It is mainly made of a rockfill dam with central core around 18 m high and 1,000 m long across the valley of the Niger River, 130 km upstream of the town of Gao in the eastern part of Mali. The dam is equipped with a 25 MW hydroelectric power plant, a lock, a dock and a spillway. The spillway is made of a gated ogee crested weir divided into 10 bays and a downstream stilling basin, with a maximum discharge capacity of 3,100 m³/s. 210 km of high tension overhead cables and a 130 km long road complete the Project. The multipurpose Taoussa dam will enable the sustainable development of the Project area by securing water resources, increasing low-water level discharges downstream, creating a link between road and fluvial transports (dock) and producing electricity. The Ministère de l’Energie, des Mines et de l’Eau du Mali - Autorité pour l’Aménagement de Taoussa -commissioned Coyne et Bellier – Tractebel Engineering in 2006 to perform the detailed studies for the Project. In this framework, the hydraulic studies have been performed by the Laboratory of Engineering Hydraulics (HECE) of the University of Liege. These hydraulic studies, depicted in details in the paper, have been carried out successively by two complementary approaches: a first step realized on the basis of numerical modelling to study the flows at the scale of the reservoir and the river, and a second experimental investigation, using a scale model, to analyse in details the spillway operation conditions. They consider varied problems from large scale flow conditions in the reservoir during the spillway operation and hydrodynamic interactions between the dam, the lock and the hydroelectric power plant to validation and optimization of the hydraulic design and dimensions of the gated spillway and the stilling basin or release conditions downstream of the project structures, including the temporary derivation stage.

The Eurocodes recognise robustness as a way to ensure the structural integrity of a building frame subjected to an unforeseen event and therefore to avoid a so-called “progressive failure” mode in extreme loading situations. However few practical guidelines exist nowadays which would allow a designer to design a structure accordingly. Within the European RFCS ROBUSTFIRE project, the behaviour of steel and composite car parks subjected to localised fire leading to a column loss was investigated. Under such a scenario, the beam-to-column joints play a key role in the global structural response. Indeed, these joints, initially loaded in bending, may be subjected to elevated temperatures and to combined axial load “N” and bending moment “M”. In this paper, a methodology to predict the mechanical response of bolted composite beam-to-column joints at elevated temperatures under M-N is presented and validated through comparison to experimental tests conducted at the University of Coimbra.

Before any repair operation, an effective assessment of the concrete substrate has to be performed. Usually next to the surface reparation of concrete, evaluation of the cohesion of the superficial concrete is requested for adhesion and durability reasons. Many authors describe the influence of the surface preparation technique on the superficial cohesion of concrete or the adhesion. However, the real effects of surface preparation technique only begin to be investigated in terms of superficial microcracking or roughness quantification. This project was performed in regards to the influence of concrete substrate strength and preparation technique efficiency. The effect of the concrete removal/preparation technique is most likely dependent upon the nature and the quality of the concrete substrate. Preparation techniques are compared from the point of view of concrete removing but also potential deterioration. The visual observation of the concrete surfaces indicates that the high pressure water jetting technique induces a particular texture characterized by large waves mostly parallel to the water flow. The concrete slabs have afterwards been covered with a Self-Compacting Repair Mortar and adhesion has been characterized. [less ▲]

A systematic experimental study has been carried out to compare the residual energy at the toe of a stepped spillway of varied length considering a classical ogee-crested weir (OCW) or two different piano key weirs (PKW) at the top of the structure. Four spillway lengths have been considered on a wide range of discharge. An indirect method has been used to compute the residual flow energy at the spillway toe from water depth measurements in a horizontal channel downstream. The results indicate that uniform flow conditions, i.e. flow energy at the spillway toe independent of the spillway length, are reached on significantly shorter spillways downstream of a PKW than downstream of an OCW. However, the uniform flow energy at constant discharge on the spillway is found to vary depending on the weir type. In particular, it is smaller downstream of the OCW than downstream of the PKWs.

Over the last years, several approaches to analyze nuclear medicine imaging using computer systems have been proposed with the aim of assisting the diagnosis of neurodegenerative disorders. Probably one of the most complex challenges facing these approaches is to deal with the huge amount of data provided by brain images. In this work, we propose an original approach based on multiple kernel learning. First the images were parcellated (according to the structure of the brain) by means of the automatic anatomical labeling atlas. Then, the importance of each region for the assisted diagnosis was estimated using a classifi- cation procedure. Finally, all the regions were combined in a multiple kernel method in which one kernel per region was computed and all the kernels were weighted according to the importance of the region they represented. For testing purposes, a database with 46 PET images from stable mild cognitive impairment subjects and early Alzheimer’s disease converter patients was used. An accuracy rate of 73.91% was achieved when differentiating between both groups. [less ▲]

Due to their trade value, a huge range of artistic materials are documented and recorded in historical written sources. However, certain substances are not registered in these archives because they did not have a market value. This is especially the case for vegetal species which artists easily found in nature and used for their colouring principles, like anthocyanin colorants. As they are characterized by a great sensitivity to the slightest changes in pH and as they are highly unstable in ordinary daylight, these colorants were not frequently used in the dyeing of quality materials or in painting. Up until now, they have been mainly considered as being used in a domestic context, for the dyeing of everyday clothes. Moreover, after ageing, the plant species are difficult to identify with currently-used analytical methods. We therefore intend to bring to light these « elusive » substances through the close examination of an original and primordial source : artistic recipe books. Our previous researches have highlighted that these books not only describe these organic colorants, but that they also indicate their use in illumination. From the 14th to the 16th century, hundreds of recipe books containing information relating to these colorants were produced. They describe both their preparation, their diverse applications and the required conditions for their conservation. These recipe books also inform us about the different hues obtained from these colorants. Our study will involve analysing the significance of these organic substances as well as (re)defining their use with a view to increasing our knowledge of historical artistic practices and materials. Furthermore, it could also help to identify specific artistic productions or workshops. Finally, it would be possible to learn more about the status of artists, their working conditions and their training. [less ▲]

This contribution discusses a coupled two-scale framework for hydro-mechanical problems in saturated heterogeneous porous geomaterials. The heterogeneous nature of such materials can lead to an anisotropy of the hydro-mechanical couplings and non-linear effects. Based on an assumed model of the mesostructure, the average macroscopic hydro-mechanical behaviour is extracted by means of a computational homogenisation procedure in a monolithic way. The ingredients needed to upscale the hydro-mechanical couplings are outlined. The two-scale simulation results are compared with direct numerical simulation for the consolidation of a particle-matrix porous material. [less ▲]

This paper identifies research opportunities which will enable the further integration of inland waterway transport in the intermodal supply chain. Intermodal transport may be interpreted as a chain of actors who supply a transport service. Inland navigation can play a crucial role in increasing supply chain service performance. A first group of research challenges has the objective to encourage efficient operations in IWT: development of a system wide model for IWT, integration of operational planning systems and analysis of bundling networks. A second group of research efforts is directed towards shippers and consignees who use the intermodal transport chain to send or receive their goods: further development of models that integrate intermodal transport decisions with supply chain decisions and creation of green supply chains. A third group of research challenges concerns the problem domain of external cost calculations. Finally detailed time series data on freight transport should be collected to support these future research tracks. [less ▲]

Pris en tenaille entre les élections du 2 juin et la publication de la Lettre au Roi, le congrès wallon de Liège du 7 juillet 1912 reste peu connu. En termes de souvenir collectif et d’inévitable hiérarchisation des événements historiques, ce sont bien deux autres congrès wallons, tenus à Liège également, qui surnagent : le congrès « identitaire » de 1905 et le fameux congrès national d’octobre 1945. Pourtant, le congrès de 1912 a eu au moins deux implications fondamentales : entretenir, au cœur de l’été le débat sur la séparation administrative, qui rebondira après la lettre de Destrée, et acter la désignation d’un comité d’action wallonne dont les premiers noms sont proposés en séance. C’est l’origine de l’Assemblée wallonne. Notre contribution proposera d’abord un bref résumé des débats ayant animé le congrès, en montrant les nuances entre le compte rendu officiel et celui des observateurs présents. Elle s’emploiera ensuite à analyser la réception du congrès dans l’opinion en insistant sur l’idée de séparation administrative. Qui se dit séparatiste ? Que recouvre cette expression, entre provincialisme et régionalisme ? Quels sont les arguments des partisans et des adversaires de la séparation ?

This paper presents a study regarding the determinants of travellers’ mental knowledge of public parking facilities. The data regarding the mental knowledge were collected in the city of Hasselt, Belgium, by means of an internet-based questionnaire. In total 1007 respondents completed the questionnaire. Two different dependent variables were specified: the mental representation of parking facilities (known or not) and the identification of parking facilities (identified first or not). In addition, three different groups of determinants were included in the models: parking attributes, personal characteristics, and mental knowledge of the city. The data are analyzed using generalized estimating equations (GEE) models for binary data. The analyses show a considerable influence of the following parking attributes: type of parking facility, Park & Ride status, charged parking, number of places, and location of parking facility. Furthermore our study revealed that personal characteristics and mental knowledge of the city play a marginal role. [less ▲]

This paper presents the Bayesian Optimistic Planning (BOP) algorithm, a novel model-based Bayesian reinforcement learning approach. BOP extends the planning approach of the Optimistic Planning for Markov Decision Processes (OP-MDP) algorithm [Busoniu2011,Busoniu2012] to contexts where the transition model of the MDP is initially unknown and progressively learned through interactions within the environment. The knowledge about the unknown MDP is represented with a probability distribution over all possible transition models using Dirichlet distributions, and the BOP algorithm plans in the belief-augmented state space constructed by concatenating the original state vector with the current posterior distribution over transition models. We show that BOP becomes Bayesian optimal when the budget parameter increases to infinity. Preliminary empirical validations show promising performance. [less ▲]

Piano Key Weirs, a recent innovation in the Labyrinth Weirs geometry, have been studied for years by several research centers and laboratories all over the world. The first prototypes have already been built, mainly in France, and others are under construction in Vietnam, Algeria and India. Despite some general design equations have been proposed recently, no optimum geometry has been defined yet. Whatever its geometry, a PKW is more efficient than a standard linear weir of same width. It is also more efficient than a labyrinth weir with the same cycle shape. But the PKW geometry may appear as complex as it involves a large set of parameters. Optimization of the weir design is thus not straightforward. Using the results of a large number of systematic scale model tests carried out to analyse the effect of the main geometric parameters on the PKW discharge capacity, the paper shows how a single optimum design doesn’t exist. This is especially true when economic and technical criteria are considered instead of a single hydraulic performance criteria. Despite this observation, some general rules to design a PKW can be suggested, as well as considerations about the best value of the main ratios defining the structure geometry. The relative influence of these parameters on the PKW efficiency is also highlighted. [less ▲]

The goal of this study is to identify those factors that trigger carpoolers to share their rides and the barriers that restrain non-carpoolers from doing so. To this end, four focus group sessions were organized. In addition, information from the 2009-2010 Flemish household travel survey was analysed. From the focus group discussions, it can be concluded that the concept of carpooling is generally well known, but that the media attention and stimuli for the topic seem to have faded away over time. The main motivations to carpool are the social aspect, the financial benefit or a combination of both. The quantitative analysis underlined for the difference between the distinct types of employees. Furthermore, the finding that the home-work distance increases the likelihood to carpool emphasizes the importance of the financial benefits of carpooling. Financial stimuli are thought to have the most potential to increase the share of carpooling in the modal split. [less ▲]

La mondialisation et la libéralisation économique qui s’imposent dans les pays du Sud, touchent aujourd’hui largement le secteur agricole et pose la problématique du financement de l’agriculture avec une acuité nouvelle. Les agricultures familiales ont besoin de s’intensifier, de se moderniser, de financer l’innovation technique, organisationnelle, etc. Le plus souvent, leur seule capacité d’autofinancement ne suffit pas à financer cette modernisation. Leurs besoins en services financiers portent sur diverses formes de crédit mais varie suivant les catégories d’exploitants agricoles. Le présent article s’est intéressé à analyser la dynamique du financement de la production agricole en lien avec le type d’exploitation agricole. Cet essai de typologie est fait à l’aide d’une méthode statistique basée sur l’analyse multi-variée et spécifiquement une analyse en composantes principales (ACP). Cette analyse a été appliquée à un échantillon de 475 exploitants agricoles. Les résultats montrent que les exploitants agricoles sont diversifiés et sont répartis en quatre types (pauvres et vulnérables, pauvres, riches et plus prospères) qui se distinguent par leur niveau de revenu, leur capacité d’investissement et leur accessibilité aux microcrédits. Les perceptions de l’accès aux crédits et de leur utilisation varient selon les différentes catégories d’exploitants agricoles. Dans tous les cas, il se dégage que les exploitants le plus prospère développement et adoptent des stratégies qui facilitent leur accès aux crédits et ainsi à l’investissement agricole. [less ▲]

During the second half of the 2nd century B.C., the city of Bargylia, in Caria, undertook a major reorganization of the cult of Artemis Kindyas, who manifested herself to help the city when it was threatened by war. A few remarkable inscriptions provide evidence of the regulations designed to « increase the honours » of the goddess, which mainly consist in making an ox sacrifice more splendid. Less than a century beforehand, a similar situation is observed in the cult of Artemis Leukophryene in Magnesia of the Meander, and of Artemis Hiakynthotrophos in Cnidus. Based on these three examples, this paper aims at showing how these epiphanies were used to settle a given deity into its function of patron deity of the city, both from an external and from an internal point of view.

La présente étude part d’un constat selon lequel; des ménages se retrouvent dans une situation d’insécurité alimentaire lorsque leurs modes de vie et moyens d’existence ne sont pas adaptés et qu’ils n’ont pas la capacité de trouver un équilibre entre un ensemble de besoins. La demande alimentaire des ménages ne peut donc être analysée indépendamment de l’ensemble des moyens d’existence et conditions de vie des ménages: relations sociales, ressources disponibles, localisation géographique. Trois quartiers de la ville de Kinshasa ont été choisis en fonction de leur niveau présumé de richesse afin d’analyser les modes de consommation alimentaire des ménages. Il s’agit du quartier Résidentiel de la commune de Limete (quartier aisé), les quartiers 1 et 7 dans la commune de Ndjili (quartier moyen) et le quartier Mabulu dans la commune de Makala (quartier pauvre). Le suivi rapproché de 30 ménages a permis de mettre en évidence les liens entre les modes de vie et les modes de consommation alimentaire. S’agissant des modes de vie, il a été identifié que pour accéder à l'alimentation, les ménages ont développé deux stratégies: la diversification des sources des revenus et la diversification des pourvoyeurs de revenus. Le nombre de sources de revenu par ménage est respectivement de 4 dans les ménages moins aisés et de 2 dans les ménages moyens et dans les ménages aisés. Ce nombre tend à augmenter avec la détérioration des conditions de vie. Le revenu hebdomadaire des membres des ménages a été estimé à respectivement 602 USD quartier aisé, 181 USD dans le quartier moyen et 41 USD dans le quartier pauvre. S’agissant des modes de consommation alimentaire, l’étude a montré que :la part des dépenses des céréales tend à diminuer dans les ménages moins aisés. Les racines et tubercules présentent une tendance opposée à celle des céréales. Ce sont les ménages les moins aisés qui consacrent la part relative la plus importante des dépenses pour l’achat des racines et tubercules soit 27% des dépenses alimentaires. Les légumineuses semblent également avoir une grande importance relative chez les ménages les moins aisés. Les ménages achètent davantage de viandes que de poissons. Les fruits sont des produits dont la consommation est saisonnière. La consommation des oeufs sous-forme d’omelette préparée hors ménage est très prisée par les ménages les moins aisés. Dans les ménages aisés, le lait est plus consommé que le sucre, la tendance est inversée pour les moins aisés. La quantité d’aliments consommés/personne/jour a été estimée respectivement à 1 120 grammes dans les ménages aisés, 801 grammes dans les ménages moyens et 493 grammes dans les ménages moins aisés. Les apports énergétiques/personne/jour sont respectivement estimés à 2452 calories dans les ménages aisés, 1838 calories dans les ménages moyens et 1130 calories dans les ménages pauvres. Les apports protéiques/personnes/jour sont respectivement dans l’ordre de 100grammes dans les ménages aisés, 80grammes dans les ménages moyens et 50grammes dans les ménages pauvres. La consommation de protéine ne semble pas être largement déficitaire tant dans les ménages aisés que dans les ménages pauvres. [less ▲]

A l’heure où l’industrie cimentière est majoritairement responsable de la production de CO2 dans le secteur de la construction, il s’avère utile de compenser cette production par un phénomène inverse: la captation du CO2. Ce processus d’absorption de CO2, appelé carbonatation, améliore certaines propriétés du béton lors de la conversion du dioxyde de carbone CO2 en carbonate de calcium CaCO3. Les préoccupations environnementales actuelles motivent l’étude de la carbonatation dans le but de maximiser l'absorption du dioxyde de carbone. Les granulats recyclés, produits à base de déchets de béton concassés mécaniquement, peuvent prendre place dans de nouvelles applications en béton. Ils peuvent remplacer les granulats naturels en tout ou en partie, épargnant ainsi l’extraction des matières premières naturelles. La combinaison des deux approches vise à élaborer un produit dont l’impact environnemental est réduit au minimum. [less ▲]

A death-ride is a long cable anchored between two dead ends, allowing the crossing of wide valleys. Besides these mobility purposes, it is also operated in rescue operations, or simply for leisure. From a serviceability viewpoint, a death-ride design should offer a comfortable and/or enjoyable journey to the riders, which is typically expressed in terms of maximum velocity. From a strength viewpoint, a death-ride should be designed in order to safely withstand the cable self-weight, wind forces, the rider’s load and at last but not least, the initial tension in the cable. Actually, the tensioning operation is usually subtle. Indeed, in case of a loose cable, the rider may be stopped in the in-span sagging area. Conversely a too tight cable will generate large stresses but also large outlet velocity at the end of the ride. The design of a death-ride is a tradeoff between all these aspects. The paper presents the dynamic model that was used for the design of a 1.2km long death-ride, with an only 10-mm diameter, a constraint fixed in the very first stages of this project for compatibility reasons, with the existing equipment. This death-ride, built and used in May 2010 in a Grimp competition [1], has a world record of the longest death-ride in urban area. The structural part of the dynamic model is rather common, with a co-rotational description of the cable by means of a chain-like model [2]. An interesting feature, however, concerns the interaction between the rider and the cable. In fact, because the pulley is rolling on the cable, the position of the force acting on the cable, resulting from the ride, depends on the rider’s velocity, which itself depends on the cable inclination. This coupling is solved in a staggered manner, and the details of the algorithm are given in the full paper. In some limiting cases, a comparison with analytical solutions is also provided, where these analytical solutions are available [3]. Experimental validation and observation of the operated death-ride will also be presented. [less ▲]

The recently developed SSH3D solid-shell element, which is based on the Enhanced Assumed Strain (EAS) and the Assumed Natural Strain (ANS) techniques, is utilized for the modeling of a severe bending sheet forming process. To improve the element's ability to capture the through thickness gradients, a specific integration scheme was developed. In this paper, the performances of this element for the modeling of the T-bent process were assessed thanks to comparison between experimental and numerical results in terms of the strain field at the outer surface of the sheet. The experimental results were obtained by Digital Image Correlation. It is shown that a qualitative agreement between experimental and numerical results is obtained but some numerical parameters should be optimized to improve the accuracy of the simulation predictions. In this respect, the influence of the penalty coefficient of the contact modeling was analyzed. [less ▲]

Hypoxia Inducible Factor (HIF) has important roles in promoting pro-inflammatory and bactericidal functions in myeloid cells. Conditional genetic ablation of its major subunit Hif1alpha in the myeloid lineage consequently results in decreased inflammatory responses in classical models of acute inflammation in mice. In contrast, we observed that mice conditionally deficient for Hif1alpha in myeloid cells display enhanced sensitivity to the development of airway allergy to the experimental allergen ovalbumin as well as to house dust mite antigens. Following allergen exposure, these mice indeed developed enhanced allergen-specific T cell responses due to augmented activation of lung dendritic cells. Further analyses supported the idea that upon allergen exposure, MyD88-dependent upregulation of Hif1alpha boosts the expression of the immunosuppressive cytokine Interleukin (IL)-10 by lung interstitial macrophages. Interstitial macrophage-derived IL-10 in turn counteracts allergen-induced lung dendritic cell activation, consequently preventing the development of allergen-specific T cell responses. Thus, this study supports that, in addition to its known pro-inflammatory activities, myeloid Hif1alpha possesses immunoregulatory functions implicated in the prevention of airway allergy. [less ▲]

This paper analyses the contribution of three programs of poverty reduction in Rwanda. It uses data from different reports and surveys with beneficiary poor households of social protection programs. The activities developed by these programs have allowed the poor in general and the widows of genocide in the Eastern Province of Rwanda in particular to improve their socioeconomic conditions, notably access to education, accommodation and medical care. Moreover, the beneficiaries have developed activities that diversify households’ revenues and improve their economic resilience. [less ▲]

Recent researches showed the rapid aeration of the flow downstream of piano key weirs. This could be related to the specific geometric features of the structure, creating several interacting flows and jets downstream. In order to validate this assumption, an experimental research has been carried out at the Laboratory of Engineering Hydraulics, University of Liège. The main objective of the study was to an-alyze the energy dissipation occurring in skimming flow conditions on a stepped spillway downstream of a piano key weir (PKW). Comparison with energy dissipation on a stepped spillway downstream of a standard ogee crested weir has been performed. An indirect method has been used to determine the resid-ual energy at the spillway toe. The results show that uniform flow conditions are reached faster on a stepped spillway downstream of a PWK compared to the length needed downstream of a standard ogee crested weir. Extrapolation of the results to prototype flow conditions is also discussed with regards to scale effects influence. [less ▲]

Network Intrusion Detection Systems (NIDSes) face significant challenges coming from the relentless network link speed growth and increasing complexity of threats. Both hardware accelerated and parallel software-based NIDS solutions, based on commodity multi-core and GPU processors, have been proposed to overcome these challenges. Network Intrusion Detection Systems (NIDSes) face significant challenges coming from the relentless network link speed growth and increasing complexity of threats. Both hardware accelerated and parallel software-based NIDS solutions, based on commodity multi-core and GPU processors, have been proposed to overcome these challenges. This work explores new parallel opportunities afforded by many-core processors for high performance, scalable and inexpensive NIDS. We exploit the huge many-core computational power by adopting a hybrid parallel architecture combining data and pipeline parallelism. We also design a hybrid load balancing scheme, using both ruleset and flow space partitioning. Furthermore, the proposed design leverages particular features of the processor to break the bottlenecks. We have integrated the open source NIDS Suricata into our proposed design and evaluated its performance with synthetic traffic. The prototype exhibits almost linear speedup and can handle up to 7.2 Gbps traffic with 100-bytes packets. [less ▲]

This paper reviews the experience of the Ramses Project in constructing a richly annotated corpus of Late Egyptian that consists of 300 000 words in 2011 (and is expected to grow up to more than 1 million words in coming years). During the first five years of the project, this corpus has been encoded in hieroglyphic script, translated in French or English and received annotations for part-of-speech information, lemmatization, and morphological analysis. The methodology and working tools that have been developed in order to build this corpus are here discussed and future developments are presented. [less ▲]

In this paper, we present a programmable platform for middleboxes called FlowOS to run on commod- ity hardware. It provides an elegant programming model for writing ow processing software, which hides the complexi- ties of low-level packet processing, process synchronisation, and inter-process communication. We show that FlowOS itself does not add any signi cant overhead to ows by pre- senting some preliminary test results. [less ▲]

The article aims at characterizing forms and functions of the uses of Middle Kingdom art in royal and court productions during the Thutmosid Period. In order to assess this artistic phenomenon as a conscious revival and not just a survival of the Past and of the tradition, the analysis starts with a brief examination of the disruption that was felt and expressed during the Second Intermediate Period. It then goes on investigating the evolution of the references to Middle Kingdom art from the dawn of the 18th Dynasty to the time of Hatshepsut and Thutmosis III, when some sorts of artistic quotations replaced a global renaissance of Middle Kingdom forms of expression. A special attention is paid to the relationship between creativity and archaism under the reign of Hatshepsut, and leads to conclude the article with some theoretical deductions on the study of Ancient Egyptian archaism and a tentative definition of how innovation was conceptualized in Ancient Egyptian culture.

Organic farming is more and more considered as a credible alternative to conventional agriculture, being able to solve current problesm, notably with respect to environment, employment and food safety. In the South of Belgium, Wallonia, organic farming represents today a significant part of agriculture. The goal of this paper is to show the growth of organic farming in Wallonia, to examine the present situation and to analyse the public support granted to organic farming, through direct payments but also through a new regional development plan including research, extension, promotion and the definition of quantified targets concerning economic activity and consumption. The results are based on statistical data collection and on a Survey among organic cereals producers, in order to contribute to the assessment of the economic relevance of organic farming. [less ▲]

Rwanda is a landlocked country, situated in central and east Africa. It is one of the poorest countries in world, 166th in 186 classified (IDH, 2012). The poor households poverty are shown decreasing from 58.9% in 2000/01 (EICV1) to 44.9% in 2010/11 (EICV3) . At the same period, extreme poverty shows similar patterns; on national level it fell from 40% in 2000/01 to 24.1% in 2010/11. This paper analyses the contribution of the social protection programs to poverty reduction of household beneficiaries: (1) The Vision 2020 Umurenge Programme (VUP) – an Integrated Local Development Program which has trees components: (i) Direct support (DS) for the poorest people who are not able to work. (ii) Public Works (PW) – this component promote the rural employment on productive community assets development projects and (iii) Financial Services (FS) – which increase the access to financial services for the poor for providing loan at low interest rate. (2) The Girinka programme as known “one cow per one poor family”. The programme aims at enabling poor household to own and manage an improved dairy cow which would help the family to better their livelihood through increased milk and meat production and to improve soil fertility of their land for their crops using the available manure. After presenting briefly the achievements, we will compare the socio-economic conditions of genocide windows before and after launching these programs in Munyiginya Sector in Rwamagana Districts.

La description qui en est faite met l'accent sur les objectifs annoncés et sur la méthodologie originale qui y est mise en place. Pour compléter le tableau, les différentes initiatives qui naissent actuellement dans le paysage belge sont évoquées, trouvant logiquement leur place parmi les perspectives de la formation en TIC des enseignants.
