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.

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 ▲]

The present study aimed at adapting and testing a French version of Kreutzer et al.’s metamemory interview (1975) in a group of 128 children aged of 4, 6, 9, and 12. Following Fritz et al. (2010), adjustments have been made to reduce language skill contamination as well as to increase the developmental appropriateness and sensibility of the scale. Results show the emergence of two sub-scales (“strategy knowledge” and “general memory knowledge”) on the factor analysis and reveal an excellent interrater reliability as well as a good internal consistency for the global scale and two sub-scales (respectively, Cronbach α = .79; .81 and .71). As expected with regard to the literature, a significant correlation has appeared between the metamemory scale and short-term memory capacities (convergent validity). Similarly, the metamemory score has shown its ability to predict children memory performance (predictive validity). Finally, the lack of correlation between most of the scale’s items and vocabulary measurement (Peabody Picture Vocabulary Test) and the very good ability of the scale to distinguish between age groups demonstrate that the adaptations made to improve the Kreutzer et al.’s scale in terms of language’s contamination and developmental sensibility have reached their goal. Regarding its psychometric properties, these results suggest that this interview can be considered as a useful and reliable tool for developmental research. Furthermore, they confirm the importance of metamemory knowledge in memory performance. Future studies will have to be carried out to show the utility of this scale in a clinical population.

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 ▲]

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.

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.

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.

L’acception du terme ornement diffère d’un traité d’architecture à l’autre, et recouvre, parfois au sein d’un même ouvrage, deux concepts qu'aujourd’hui nous tendons à opposer : le structurel et l’accessoire. Or, si ces deux notions sont replacées, à leur juste mesure, dans la théorie de l’architecture des Temps Modernes, il apparaît clairement que l’ornement, – qu’il soit défini comme un élément de support dans le système des ordres ou comme la décoration générale d’un édifice –, occupe un rôle essentiel dans la conception totale d’un espace bâti, dans laquelle « toutes les parties d’Architecture, de Sculpture, & de Peinture ne doivent faire ensemble qu’un seul & même tout » (Boffrand, 1745). A ce titre, l’ornement assure donc pleinement la fonction sociale, économique, politique… dévolue communément à l’architecture. Dans cette communication, nous proposons d’aborder l’ornement en sa qualité d’élément de composition de l’espace bâti. Plus précisément, à travers les discours des théoriciens français de l’architecture du XVIe au XVIIIe siècle, nous étudierons la façon dont l’ornement intervient dans la question de la distribution des édifices ; cet art français par excellence d’organiser et de définir les espaces de vie.

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.

La question qui se pose d’emblée est celle du sens de ce type de figuration, qui « redouble » en quelque sorte la divinité.

In real-time operation, the aim is to arbitrate in a rational way between preventive and corrective control, while taking into account i) the prior probabilities of contingencies, ii) the possible failure modes of corrective control actions, iii) the socio-economic consequences of service interruptions. This work is a first step towards the construction of a globally coherent decision making framework for security management from long-term system expansion, via mid-term asset management, towards short-term operation planning and real-time operation.

Activity-based micro-simulation models typically predict 24-hour activity-travel patterns for each individual in a study area. These patterns reflect the characteristics of the available transportation infrastructure and land-use system as well as individuals’ lifestyles and needs. However, the lack of a reliable benchmark to evaluate the generated patterns has been a major concern. To address this issue, we explore the possibility of using mobile phone data to build such a validation measure. Our investigation consists of three steps. First, the daily trajectory of locations, where a user performed activities, is constructed from the mobile phone records. To account for the discrepancy between the movements revealed by the call data and the real traces that the user has made, the daily trajectories are then transformed into travel sequences. Finally, all the inferred travel sequences are classified into typical activity-travel patterns which, in combination with their relative frequencies, define a profile. The established profile represents the activity-travel behavior in the study area, and thus can be used as a benchmark for the validation of the activity-based models. By comparing the benchmark profiles derived from the call data with statistics that stem from activity-travel surveys, the validation potential is demonstrated. In addition, a sensitivity analysis is carried out to assess how the results are affected by the different parameter settings defined in the profiling process. [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 ▲]

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.

When a repair operation is performed and a new concrete or mortar is applied on the old concrete substrate, it is very important to have a good bond between the old concrete layer and the repair concrete system. The bond strengths usually determinate using pure tensile tests (pull-off tests) because of the field applicability of this category of tests. However, in most of the applications, shear stress is the main reason of the bond failure. In general, bond strength under tensile is considered smaller than bond strength in shear stress conditions. The objective of this paper is to compare the results obtained from tensile and shear tests and to potentially determine a mathematical relation between shear and tension. The materials used for tests are Ordinary Portland Cement and modified limestone fillers mortars. Specific humidity storage conditions have been selected. [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.

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 ▲]

Rapid rotation has to date prevented reliable mode identification in most intermediate to massive pulsating stars. In this contribution we show how an asymptotic method for pressure modes predicts regular frequency spacings in the spectrum of rapidly rotating stars. We give a semi-analytical formula for these spacings that is in good agreement with numerically computed high-frequency modes. This should help to extract from observed spectra important information on the structure of rapidly rotating stars. [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 ▲]

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.

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 ▲]

The aim of the present review is to summarize the achievements on pregnancy-associated glycoproteins in sheep during the last 20 years on terms of results obtained after purifications, molecular biology, radio-immunoassays (RIA), enzyme linked immune sorbent assay (ELISA), double radial immune-diffusion (Ouchterlony) and Western blot techniques. The analysis of documented papers that concerned these attempts showed that the animal genetic material used was composed of variable breeds from north Africa, Europe and USA (the Aragonesa, Ouled Djellal, Laucaun drairy sheep, Berrichone, Texel x Norvegian crossed ewes, Awassi x Merino, Blackheaded Moutton sheep x Blackheaded German Mutton sheep (BGM), Rhoen sheep crosses of BGM with Dorper sheep, Assaf, Chura, Merino, Texel, Suffolk, Boujaâd Moroccan breed). The RIA represents the wildspread technique used (54%) while Oucherlony and Western blot had been limited in use (4% each). From 1990 to 2000 only 27% of the achievements being available today were realized. The main data, profiles and studies were performed from 2000 to now (63%). To conclude, this review allows summarizing and updating the knowledge about the PAG in sheep. [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”.

Virtual routers are increasingly being studied, as an important building block to enable network virtualization. In a virtual router platform, multiple virtual router instances coexist, each having its own FIB (Forwarding Information Base). In this context, memory scalability and route updates are two major challenges. Existing approaches addressed one of these challenges but not both. In this paper, we present a trie merging approach, which compactly represents multiple FIBs by a merged trie and a table of next-hop-pointer arrays to achieve good memory scalability, while supporting fast incremental updates by avoiding the use of leaf pushing during merging. Experimental results show that storing the merged trie requires limited memory space, e.g., we only need 10MB memory space to store the merged trie for 14 full FIBs from IPv4 core routers, achieving a memory reduction by 87% when compared to the total size of the individual tries. We implement our approach in an SRAM (Static Random Access Memory)-based lookup pipeline. Using our approach, an on-chip SRAM-based lookup pipeline with 5 external stages is sufficient to store the 14 full IPv4 FIBs. Furthermore, our approach can guarantee a minimum update overhead of one write bubble per update, as well as a high lookup throughput of one lookup per clock cycle, which corresponds to a throughput of 251 million lookups per second in the implementation.

In this chapter, we show that two-dimensional oscillation codes help us to improve our knowledge of the effects of rapid rotation on acoustic (p) and gravity (g) modes. We first discuss how to solve the full problem of stellar oscillations in rapidly rotating stars by including the effects of the Coriolis force as well as those of the centrifugal distortion. We illustrate the development and the validation of a 2-D code using the Two-dimensional Oscillation Program (TOP) as an example. We then describe what strategies are being developed to explore the p- and g-mode spectra, how effective these methods are, and what intrinsic difficulties they face. In the last part of this chapter, we present results obtained with these techniques. [less ▲]

Inbreeding depression results from mating among genetically related individualsand impairs reproductive success. The decrease in male matingsuccess is usually attributed to an impact on multiple fitness-related traitsthat reduce the general condition of inbred males. Here, we find that the productionof the male sex pheromone is reduced significantly by inbreeding inthe butterfly Bicyclus anynana. Other traits indicative of the general condition,including flight performance, are also negatively affected in malebutterflies by inbreeding. Yet, we unambiguously show that only the productionof male pheromones affects mating success. Thus, this pheromonesignal informs females about the inbreeding status of their mating partners.We also identify the specific chemical component, hexadecanal, probablyresponsible for the decrease in male mating success. Our results advocategiving increased attention to olfactory communication as a major causalfactor of mate-choice decisions and sexual selection.Published in the Proceedings of the Royal Society of London (2013) in press.

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 ▲]

Garantir la durabilité d’une filière de production implique d’évaluer son impact sur les trois dimensions du développement durable : (1) maîtrise des impacts sur l’environnement, (2) viabilité économique, (3) attentes sociétales des éleveurs, des citoyens et des consommateurs. Cette recherche s’inscrit dans le cadre de la révision, par les autorités publiques de Wallonie (Belgique), des critères minimaux permettant la reconnaissance de la qualité différenciée axés sur les 3 piliers de la durabilité. Elle consiste à développer un outil informatique de modélisation mathématique du fonctionnement technico-environnemental de la production porcine et de ses impacts socio-économiques. Le programme est développé dans Matlab. Le modèle s’articule autour des différentes composantes des systèmes de production selon le paradigme orienté-objet. Les nouveaux critères de différenciation qui définiront de nouveaux labels axés sur des attributs de durabilité en constituent les variables motrices : taille de l’exploitation, origine des aliments et des matières premières, logement, indépendance énergétique, effluents, etc. Les impacts sont relevés à chaque étape de production jusqu’à la sortie du porc sur pied de la ferme selon la norme « Analyse de Cycle de Vie » (ACV). L’évaluation environnementale utilise des modèles mécanistiques de flux de composés chimiques, convertis en indicateurs ACV. L’analyse de la dimension sociale s’appuie sur une base de données intégrée, comprenant le temps de travail. Enfin, un modèle économique attestera du dernier volet. L’outil finalisé permettra de prédire les conséquences de choix opérationnels liés aux critères de qualité différenciée au niveau d’une exploitation. [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 ▲]

In recent years, several approaches to develop computer aided diagnosis systems for dementia have been pro- posed. The purpose of this work is to measure the advantages of using not only brain images as data source for those systems but also some psychological scores. To this aim, we compared the accuracy rates achieved by systems that use psychological scores beside the image data in the classification step and systems that use only the image data. The experiments show that the formers achieve higher accuracy rates regardless of the procedure carried out to analyze the image data. [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 ▲]

The non Gaussian buffeting analysis of a structure subjected to turbulent wind may be advantageously performed with a Volterra approach. Although this concept may be applicable to nonlinear structures, the scope of this paper is limited to structures with a deterministic linear behavior. In this case, the Volterra kernels take a simple explicit expression and the statistical moments of the structural response are simply recovered by a multi-dimensional integration of the corresponding spectra. Because the multi-dimensional spectra of the loading are usually determined numerically, these integrals have to be computed numerically too. The computational burden necessary for the estimation of these integrals turns out to be prohibitive as soon as high order moments are required (beyond and including 4th moment). The numerical conditioning is in fact again worse when the structural damping is low as the Volterra kernels then exhibit very large gradients in the frequency space, which are difficult to capture properly. Because the timescales related to the dynamics of the structure and to the random wind loading are well distinct, a nowadays customary decomposition of the response into Background and Resonant contributions (dating back to A. Davenport's earliest works) provides a very good estimation of the second statistical moment. Recently the concept has been extended to the Background/biResonant decomposition for the estimation of the third statistical moment of the response. This paper presents the extension to the computation of the fourth statistical moment, with the only assumptions of slight damping and low-frequency loading such as those that made Allan Davenport's Background/Resonant (B/R) decomposition fruitful. After some multiple scales considerations, the fourth moment of the response is approximated as the sum of a background component, a tetraresonant component and a mixed background-biresonant component. Mathematical developments will be presented in the full paper along with illustrative examples, while the current 4-page abstract just presents of a flavour of it. [less ▲]

This paper describes a study of car drivers’ familiarity with the parking situation in the vicinity of a regional shopping center. The data used for this study are collected in Hasselt, a medium sized city in Belgium. The central shopping area of Hasselt is surrounded by 23 public parking facilities. 1007 residents have been asked to indicate if they are familiar with each parking facility. The concept of familiarity was related to the socio-demographic and cognitive attributes of the respondents, their trips to the city center and the type of parking facility using multinomial logistic regression and bivariate probit regression. The results show that familiarity with parking facilities is especially related to age and education, and to the frequency of car use towards the city centre, and to a lesser extent to place of residence, income and perceived mental knowledge. In addition to these results, this paper demonstrates the value of collecting virtual buffer data by means of an online survey tool. The authors recommend that simulation models that predict parking choice behavior take into account the different levels of familiarity with parking facilities, and the contributing factors. An important avenue for further research is the combination of personal and facility specific information to assess the familiarity with different types of parking facilities. [less ▲]

This paper reports on the construction-based Treebank currently under development in the frame-work of the Ramses Project, which aims at building a multifaceted annotated corpus of Late Egyptian texts. We describe the specifications that have been implemented and we introduce the syntactic formalism and the related representation format that are used for the syntactic annotation. Further-more, the annotation scheme is discussed with particular attention paid to its evolutionary nature. Finally, we explain the methods as well as the annotating tool, called SyntaxEditor; we conclude by addressing the question of forthcoming developments, especially the search engine and a context-sensitive parser.
