The present paper proposes a codicologic, palaeographic and contextual study of an extraordinary Late Antique book: the Montserrat codex miscellaneus. Dated on palaeographic grounds to the IV century AD, this manuscript provides us with evidence of particular interest on bilingualism and digraphism in Byzantine Egypt, for it is the only antique codex containing texts in both Greek and Latin, of both Christian and Secular content, and pertaining to different literary genres, such as rhetoric, hexametric poetry and Christian liturgy.

The aim of the present study was: i) to investigate the use of PAGs for pregnancy follow up in Boujaâd non prolific (n=8) vs. Boujaâd x D’man a prolific sheep (n=20), ii) to study whether the boPAG tracer (daily available at the laboratory of physiology of reproduction, Liège, could be used in RIA without affecting the results, iii) to prospect the possibility of transferring the technique to a Moroccan laboratory. The blood samples were weekly collected from the first week of gestation till the 4 week after lambing. The RIA1, RIA2, RIA3 and RIA4 were all based on ovPAG standard, while the tracer and antiserum changed according to the system. The RIA1, RIA3 and RIA4 were performed in Belgium while the RIA2 was carried out in Morocco. The results showed that the highest correlation was obtained between the RIA3 and RIA4 (R2 = 0.83) while the lowest was recorded between the RIA2 and RIA4 (R2 = 0.69). The lowest concentrations derived from the RIA2. The highest concentrations were recorded before lambing (279.29; 88.21; 268.75; 152.67 ng/ml respectively for RIAs 1, 2, 3 and 4). To conclude, the profiles of ovPAG showed that it is possible to flow-up with success using the four systems. In addition, the RIA1 using boPAG as tracer could be a good alternative to the homologous one and finally, it is possible to set up routinely the RIA technique for PAG detection in Moroccan laboratories.

Lower airway diseases are common problems in sports and racing horses. In humans, exercise has been associated with upper respiratory tract infections due to down-regulated expression of Toll-like receptors (TLRs), costimulatory and antigen-presenting molecules on monocytes. The objectives of this study were 1) to examine the expression of TLRs in equine bronchial epithelial cells (EBEC) and blood monocytes in untrained and trained horses; 2) to stimulate EBEC and monocytes in vitro with TLR ligands, in order to mimic bacterial/viral infections; 3) to compare the cytokine production of EBEC and monocytes in untrained and trained horses. Bronchial biopsies were taken from 8 horses during lower airway endoscopy at rest and 24 hours after a standardized exercise test (SET). Bronchial epithelial cells were grown in vitro and activated with TLR ligands. Blood monocytes were collected at rest and after the SET. TLR1-TLR9 expression was evaluated via real-time PCR and cytokine production was measured via ELISA. TLR3 and TLR4 expression was modified by training. The expression of TLR2, TLR7 and TLR8 was modified only by strenuous exercise in trained horses. Training had local immuno-suppressive effects shown by a decreased production of TNF-alpha and IFN-beta in EBEC in response to TLR2 and TLR3 ligands. Training also caused a systemic pro-inflammatory response evidenced by increased production of TNF-alpha in monocytes in response to TLR2 and TLR4 ligands. These findings suggest that training and strenuous exercise in trained subjects may result in an increased susceptibility of the lower airway to infections associated with systemic inflammation.

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 ▲]

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 ▲]

Detailed inundation modelling was conducted along a 100 km long transnational section of the Meuse River (in Belgium and The Netherlands), using very similar models for the whole computation (2D unsteady models). As a result, damping of the flood waves could be quantified and the possible relevance of using a steady-state approach could be assessed. The new detailed 2D hydraulic simulations have demonstrated that only a very limited damping of the flood waves occurs along the simulated reaches. From the perspective of the variation in peak discharge, the study concludes that running the hydraulic model in steady mode makes perfectly sense. Nonetheless, the steady computations lead to extensive overestimations of the inundated extent and of the stored volume in the floodplains. 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 Prevost’s model is currently used to model cyclic behaviour of soils especially in earthquake engineering. The original model is able to capture the main features of cyclic behaviour: pore pressure build up and plastic deformation accumulation. But accurate modelling of laboratory tests requires improvements. Enhanced models exist but require a lot of parameters that make them cumbersome for practical purpose. A suction caisson, part of a tripod offshore foundation for wind turbines is modelled. Possibilities of the Prevost’s model are highlighted compared with a classical Drucker-prager model. [less ▲]

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 ▲]

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 ▲]

Groundwater quality is spoiled by various substances resulting from human activities. In addition to pesticides, one of the most problematic substances is nitrate. Pumping prevention areas are strategic zones in terms of struggle against diffuse pollution by nitrate. In order to reduce diffuse pollution of waters by nitrate, different strategies of agricultural practices can be implemented. Their impact can be evaluated either by monitoring water quality or using an agro-hydrological model. The advantage of modelling is to be able to test long term impacts of implemented measures and impacts of complementary measures. Using EPICgrid distributed agro-hydrological model, we reproduced the current agricultural practices. We calculated nitrate leaching but also the nitrate stock in the root zone. These results were validated through a comparison with a lot of nitrogen stock measurements. (These measurements are compulsory in the Walloon context.) The nitrate concentration in pumping wells was also used to assess the efficiency of the model. After this calibration phase, we modelled several scenarios of more water-protective agricultural practices. Indeed, the Hesbaye galleries represent an important source of drinking water in the Walloon region, it is therefore highly probable that further mitigation measures are going to be imposed in the pumping prevention area. An increase in the area cultivated with cereals, a strong limitation of mineral fertilisation as well as a conversion to grasslands were tested and combined. The results of these simulations show how some agricultural practices scenarios can lead to an important decrease in diffuse pollution by nitrate. Prospective simulations taking into account possible future climate evolution (global change scenarios) are carried out to assess nitrate concentrations near the groundwater table for the deadlines of the WFD (2015, 2021 and 2027). Due to the transfer time through the vadose zone (more than 20 years in some subregions), it is showed that an increase in groundwater nitrate concentrations will occur, in some areas, until at least 2030 before new agricultural practices can impact positively the groundwater quality.

Le premier schéma fonctionne en éliminant des contraintes afin d'obtenir un problème soluble en temps polynomial. Le deuxième schéma est une relaxation lagrangienne conduisant également à un problème soluble en temps polynomial.

This paper is a first step in applying machine learning methods typical of Automated Text Catego-rization (ATC) for Automatic Genre Identification (AGI) in Late Egyptian, a language written in either hieroglyphic or hieratic scripts that is found in documents from Ancient Egypt dating from ca. 1350-700 BCE. The study is divided into three parts. After a general intro¬duction on AGI (§1), we introduce the levels of annotation that are integrated in the Ramses corpus and can be used when performing AGI on Late Egyptian (§2). In the following section (§3) we offer a brief survey of the types of features that have been discussed in the literature on AGI, before proceeding with three case studies where we apply supervised machine learning methods — namely the naïve Bayes classifier (§4.1), the Support Vector Machine (§4.2), and the Segment and Combine approach (§4.3) — to a selection of texts in the corpus. Their respective performances are tested using lexical, part-of-speech and inflectional features. [less ▲]

Etude des relations entre les pères et leur(s) fille(s) dans le Cycle de Guillaume d'Orange, et en particulier dans sa mise en prose, qui récrit vers 1450 treize des vingt-quatre chansons du cycle, pour voir si ce texte tardif modifie les données des poèmes quant à ce lien de parenté. Sont étudiés les aspects affectifs de la paternité et le rôle des pères dans la destinée des filles, ce qui permet d'envisager la manière dont est traitée dans les textes littéraires la problématique du consentement des filles au moment du mariage. Alors que Boniface représente pour Hermengart un père affectueux et attentif aux souhaits de son héritière, Aymeri et Louis sont pour leurs filles respectives des pères peu impliqués, qui délèguent à Guillaume la négociation des alliances matrimoniales. C'est donc un frère ou un oncle maternel qui se substitue à un père encore actif pour régler le sort des filles. Cet effacement des pères s'explique littérairement par la volonté de promouvoir le héros éponyme du cycle en chef de clan, mais la question est de savoir une réalité historique vient soutenir ce phénomène qui substitue l'autorité du frère à celle du père.

X-ray tomography is used to investigate the influence of packing geometry and of liquid viscosity on hydrodynamic quantities, as well as on the liquid flow morphology inside a packed column successively filled with two structured metallic packing, M752Y and M500X. As expected, liquid holdup and gas-liquid interfacial area increase with liquid flow rate and viscosity. In both packings, the film flow pattern predominates, while flooded regions remain minority. The influence of liquid flow rate and viscosity on flow morphology depends on the packing geometry. In M752Y, film and flooded region flows are clearly influenced, whereas in M500X, they are not.

Natural phenomena such as floods, drought, erosion, nitrate leaching and plant growth are influenced by climate change. The Soil - Water Systems division of Gembloux Agro-Bio Tech aims at studying these phenomena; better understanding processes; modelling them in order to predict their change in the future and to assess their potential consequences. Then, we can propose strategies to adapt to these changes. As an agronomy faculty, we believe that adapting agriculture can play a major role in mitigating climate evolution effects at plot and catchment scales. [less ▲]

Dans le cadre de la conception d’un expanseur dédié à la récupération d’énergie à l’échappement d’un moteur à combustion interne, une étude sur des lubrifiants solides a été menée afin de choisir le couple de matériaux adéquat pour le joint principal de la machine. Ce joint doit assurer à la fois une fonction d’étanchéité interne et limiter ainsi les pertes par fuites internes de l’expanseur. Il doit également présenter un coefficient de frottement la plus faible possible afin de réduire les pertes par friction. Ce joint est en effet sollicité par des contraintes en frottement plan dans un environnement sous vapeur d’eau à des températures pouvant atteindre 250°C. Ces températures rendent complexe l’utilisation d’huile et le recours à des matériaux auto lubrifiants est dès lors l’unique solution. [less ▲]

This paper offers an examination of three significant familial inscriptions from the Hellenistic period. The texts are detailed cultic dossiers initiated by three individuals—Diomedon on Cos, Poseidonios in Halicarnassus, and Epikteta on Thera. Though they are often very briefly grouped together, these inscriptions are discussed here in greater textual and contextual detail. In particular, the analysis focusses on the cult personnel, which is appointed in these families, demonstrating that it remains independent from the polis, but is organised with reference to a civic framework. By setting these inscriptions in parallel, the discussion opens up productive perspectives on the evolutions of familial cults in the Hellenistic period.—The inscription of Poseidonios is reedited in an Appendix by Jan-Mathieu Carbon.

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 ▲]

In this paper, we study the origins of the northern Congo Republic rainforests. Macroscopic charcoal fragments were systematically recorded through auger investigations and pits observations in four forest types: the open canopy Marantaceae forest, the dense forest with Marantaceae, the Gilbertiodendron dewevrei forest and the Triplochiton scleroxylon forest. In addition, the charred Elaies guineensis seeds were distinguished from the other charcoals in the pits. Ten selected charcoals, including charred E. guineensis seeds, were dated by AMS. Abundance of charcoal fragments in the soils at various depths indicated several episodes of fires in the region. A dryer climatic phase, between 2320 and 1330 BP, associated with a large scale human occupation related to the important harvesting of oil palm nuts, could explain the widespread Marantaceae forests. Recent slash-and-burn shifting cultivation, c. 200 BP, would allow T. scleroxylon installation. Implications for forest management are discussed. [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 ▲]

Issued under various titles between 1944 and the early 1980’s, the Belgian weekly Europe Amérique / Magazine showed itself at first rather eclectic in the choice of its writers and the articles it published. It had soon more and more pronounced leanings towards the far right and specialized itself in a vociferous form of anticommunism, the rehabilitation of Vichy regime and strong criticism of the Republic as the brain child of a biased vision of the Resistance. It opened its columns to avowed rightist French journalists ear-marked for theit conduct during WW2 and / or having their names on the black list of the Comité National des Ecrivains. After describing the inner story of the weekly, the causes and consequences of its two prohibitions in France (1946-1948, 1949-1953), this article deals with its strongly Vichy tainted staff of French writers (Alfred Fabre-Luce, Louis Guitard, Louis Rougier, Pierre Dominique, Albert Paraz, Lucien Rebatet...) and its closeness with the well-known Paroles Françaises, Ecrits de Paris and Rivarol.

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 ▲]

The Biennales of Venice are not limited to exhibitions in national pavilions. Every year artists and architects choose to confront the site and more specifically, the lagoon. In the edition of 2005, the artist O. Eliasson proposed an installation (Your black horizon, 2005) where the visitors left the wide expanse and intense light of the lagoon to enter a darkened enclosed space with subtle light effects. These aesthetic experiences enhanced the visitors’ perception of light by changing the usual spatiality and temporality of colour. We will analyze the role of memory in the rite of the visit, and look at how the museal strategies of the artist create a play with spatial memory and sense of orientation in relation to the outdoor space of the lagoon.

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 advantages of micro-electro-mechanical systems (MEMS), such as low power requirement, miniaturized sizes and costs reduction, have already made significant impact in many technological fields. MEMS are now widely used as accelerometers, pressure sensors, and resonators etc. However, the determination of the mechanical properties of MEMS devices with high accuracy is still a challenging task due to their small dimensions and often anisotropic behaviour. This paper focuses on the modelling and simulation of the fracture of a key MEMS component, which is a polycrystalline silicon beam, by discontinuous Galerkin (DG) formulation combined with an extrinsic cohesive law (ECL) to describe the fracture process. As the beam is modelled by plane-stress 2D elements, an analytical equation to compute the effective fracture strength and the effective critical strain energy release rate in terms of the through-the-thickness fracture mode and of the orientation of the facet with respect to the crystal is also developed. At the end, a model is simulated, and the results are verified as per the physics of the problem and experiments. [less ▲]

Due to the rapid development of technology, larger data sets concerning activity travel behavior become available. These data sets often lack semantic interpretation. This implies that annotation in terms of activity type and transportation mode is necessary. This paper aims to infer activity types from GPS traces by developing a decision tree-based model. The model only considers activity start times and activity durations. Based on the decision tree classification, a probability distribution and a point prediction model were constructed. The probability matrix describes the probability of each activity type for each class (i.e. combination of activity start time and activity duration). In each class, the point prediction model selects the activity type that has the highest probability. Two types of data were collected in 2006 and 2007 in Flanders, Belgium, i.e. activity travel data and GPS data. The optimal classification tree constructed comprises 18 leaves. Consequently, 18 if-then rules were derived. An accuracy of 74% was achieved when training the tree. The accuracy of the model for the validation set, i.e. 72.5%, shows that overfitting is minimal. When applying the model to the test set, the accuracy was almost 76%. The models indicate the importance of time information in the semantic enrichment process. This study contributes to future data collection in that it enables researchers to directly infer activity types from activity start time and duration information obtained from GPS data. Because no location information is needed, this research can be easily and readily implemented to millions of individual agents. [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.

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 ▲]

On rencontre, dans l’Iliade et chez Hérodote, principalement, des systèmes hypothétiques où la protase (introduite par εἰ) et l’apodose sont en outre coordonnés par μέν / δέ. Ces occurrences paradoxales peuvent être expliquées de manière satisfaisante si on sépare soigneusement le niveau sémantique (où l’hypothèse peut être expliquée) et le niveau syntaxique (où le caractère non subordonné de la protase peut être démontré) ; cette explication permet de décrire les emplois non subordonnants de εἰ sans avoir à les faire dériver d’une structure subordonnée.

The present paper addresses the experimental identification of a simplified realisation of a solar array structure in folded configuration. To this end, a nonlinear subspace identification technique formulated in the frequency domain, referred to as the FNSI method, is exploited. The frequency response functions of the underlying linear structure and the nonlinear coefficients are estimated by this approach. Nonlinearity is caused by impacts between adjacent panels and friction and gaps appearing in their clamping interfaces. This application is challenging for several reasons, which include high modal density and the complicated nature of the involved nonlinear mechanisms. [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.

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”.

This paper studies look-ahead tree based control policies from the viewpoint of online decision making with constraints on the computational budget allowed per decision (expressed as number of calls to the generative model). We consider optimized look-ahead tree (OLT) policies, a recently introduced family of hybrid techniques, which combine the advantages of look-ahead trees (high precision) with the advantages of direct policy search (low online cost) and which are specifically designed for limited online budgets. We present two extensions of the basic OLT algorithm that on the one side allow tackling deterministic optimal control problems with large and continuous action spaces and that on the other side can also help to further reduce the online complexity.

The objective of the paper is to assess the accuracy of current Direct Strength Method (DSM) equations applied to steel structural welded H shapes in axial compression. Commercialised hot-rolled H sections covering IPE, HE, HD, HL, HP, W and UB profiles and made of three grades (235MPa, 355MPa and 460MPa) were treated in (Li & Rossi 2012). This analysis focuses on welded sections made of the same three grades, including sections characterized by local buckling with a significant post-buckling reserve. The finite element model is described. Then, the results of a parametric analysis using the finite element model are re-ported. The codified resistances are also compared to the numerical results. For each cross-section, the recently developed analytical expressions provided in (Seif & Schafer 2010) for hot-rolled profiles are used to cal-culate the elastic cross-section local buckling stress. A comparison with CUFSM results is also reported. Then, the possibility to use the concept of DSM for the design of structural welded steel shapes is discussed. [less ▲]

Differential passivity is a property that allows to check with a pointwise criterion that a system is incrementally passive, a property that is relevant to study interconnected systems in the context of regulation, synchronization, and estimation. The paper investigates how restrictive is the property, focusing on a class of open gradient systems encountered in the coenergy modeling framework of physical systems, in particular the Brayton-Moser formalism for nonlinear electrical circuits.

On analyse ici les manifestations discursives de la contradiction que constitue en soi, pour le discours médiatique, un événement, et ce en faisant porter l'interrogation sur le récepteur. Il s'agit de se demander comment le média relaie le choc que constitue l'événement en nouant ensemble deux affirmations : l'événement fait quelque chose au discours médiatique et celui-ci fait quelque chose au lecteur. Cette dimension performative du discours est soutenue par la déconstruction derridienne du signe linguistique et par la notion de "partage du sensible" de Jacques Rancière. [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.

Gegenwärtig entwickelt die RWTH Aachen University im Rahmen des Projekts "Galileo above" (Anwendungszentrum für bodengebundenen Verkehr ) ein Kollisionsvermeidungssystem (Collision Avoidance System, CAS) unter Einbeziehung von Galileo-Daten. Ziel des CAS ist - wie der Name suggeriert - Fahrzeuge zu erkennen, die sich auf Kollisionskurs mit dem eigenen Fahrzeug befinden und automatisch eine kollisionsvermeidende Maßnahme (Bremsen und/oder Lenken) einzuleiten, insofern der Fahrer nicht rechtzeitig reagiert. Der begrenzte Erfassungsbereich und die Einschränkungen, der die verwendete kosten-optimierte Sensorik unter unterschiedlichsten Umgebungsbedingungen unterliegt, sind häufig ein begrenzender Faktor für die Realisierbarkeit und Robustheit von Fahrerassistenzsystemen (FAS). Der Einsatz von GNSS (Global Navigation Satellite System) in Verbindung mit einer digitalen Karte und Fahrzeug-zu-Fahrzeug- bzw. Fahzeug-zu-Infrastruktur-Kommunikation bietet das Potenzial, den Erfassungsbereich der Sensorik deutlich zu erweitern und diese unter schwierigen Umgebungsbedingungen zu stützen. Für die Entwicklung des CAS wird das Galileo Testzentrum automotiveGATE in Al-denhoven genutzt. Das automotiveGATE erweitert das Aldenhoven Testing Center um sogenannte Pseudoliten (Pseudo-Satelliten), welche Galileo-ähnliche Navigati-onsdaten in einem begrenzten Gebiet ausstrahlen. Das automotiveGATE ermöglicht somit die Entwicklung und Erprobung von Galileo-basierten Applikationen vor der Inbetriebnahme des eigentlichen Galileo-Satellitennavigationssystems. Im Rahmen dieses Beitrags werden Erläuterungen zur Perzeption und Sensorfusion, zur Deeskalationsstrategie und Eingriffsentscheidung sowie zu Testergebnissen bei Auffahrsituationen des CAS gegeben.

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.

This study was conducted during three production cycles of the third year of vegetation. The main objective was to determine the production of dry matter (DM) and crude protein (CP) made under the influence of mixture and fertilization with nitrogen on P50 agrofond to alfalfa and orchard grass. To achieve these objectives, three variants of mixture were tested between alfalfa and cocksfoot that were applied to four rates of mineral fertilizers. The mixture 75% alfalfa (Medicago sativa L.) and 25% orchard grass (Dactylis glomerata L.) under the effect of dosing with N100P50achieved the highest production increase of DM on cycle I, 108% (5.24 Mg haDM) compared to the control, unfertilized alfalfa in pure culture (4.85 Mg ha DM). The highest increase forthe CP yield was obtained on cycle I from the 100% alfalfa fertilized with doses of N-1-1100P50, 122% (1230 kg haCP) from 100% alfalfa unfertilized (1009 kg ha CP). Alfalfa fertilized with N-1-1100P50 rate had the highest increases on total DM yield (106%, 10.64 Mg haDM) and on total quantity of CP(124%, 2304 kg ha CP). [less ▲]
