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 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.

Climate change in Western Europe is projected to result in more humid winters and drier summers. Further, the sverities of floods and low flows are assumed to increase in the future. The impacts of these events could lead to adverse consequences on the economy. Given this framework, within the AMICE project, the impacts of future floods and low flow will be analyzed. A flood risk analysis in the Meuse basin is conducted taking into account future climate scenarios. Further, the impacts of future droughts and low flows are analyzed for the economic sectors energy production, agriculture and navigation. [less ▲]

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.

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.

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 ▲]

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 ▲]

Cet article décrit l'algorithme BOP (de l'anglais ``Bayesian Optimistic Planning''), un nouvel algorithme d'apprentissage par renforcement Bayésien indirect (c'est à dire fondé sur un modèle). BOP étend l'approche de l'algorithme OP-MDP (de l'anglais ``Optimistic Planning for Markov Decision Processes'', voir [Busoniu2011,Busoniu2012]) au cas où les probabilités de transitions du MDP sous-jacent sont initialement inconnues, et doivent être apprises au travers d'interactions avec l'environnement. Les connaissances sur le MDP sous-jacent sont représentées par une distribution de probabilités sur l'ensemble de tous les modèles de transitions à l'aide de distributions de Dirichlet. L'algorithme BOP planifie dans l'espace augmenté état-croyance obtenu par concaténation du vecteur d'état avec la distribution postérieure sur les modèles de transitions. On montre que BOP atteint l'optimalité Bayésienne lorsque le paramètre de budget tend vers l'infini. Quelques expériences préliminaires montrent des résultats encourageants. [less ▲]

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 ▲]

Le traitement de la mammite bovine est un acte à part dans la routine d’une exploitation bovine. En effet, si les cas les plus graves sont vus presque systématiquement pas le vétérinaire traitant en France ou en Belgique, la plupart des cas peu sévères font l’objet d’une tacite délégation de diagnostic et de traitement, sur base d’une formation préalable et d’une prescription enregistrée. Aujourd’hui, cette pathologie représente le plus important poste de consommation d’antibiotiques en exploitation laitière. Concernant cette problématique, la profession vétérinaire doit disposer de nouveaux outils de diagnostic, de traitement, et surtout d’évaluation de la qualité du traitement. Or, depuis la fin des années 1940, la pratique de l’antibiothérapie est restée, comme en médecine humaine, basée essentiellement sur l’antibiothérapie empirique, plus ou moins régulée par des cultures bactériologiques et des antibiogrammes (Durel et al., 2012). La profession s’est dotée d’outils d’analyse épidémiologique et clinique au cours des décennies, mais les résultats sont mitigés : une diminution globale de la consommation d’antibiotiques, mais le recours accru à des classes de dernières générations. Aujourd’hui le grand enjeu de l’antibiothérapie se corse, avec l’identification de mécanisme de résistance suspects d’être communs avec la médecine humaine(Jaglic et al., 2010). Plusieurs classes de molécules communes avec la médecine humaine sont identifiées, et leur utilisation menace d’être régulée (Bagcigil et al., 2007). Face à ce constat, l’utilisation des antibiotiques destinés au traitement de la mamelle a été étudiée en Belgique, dans soixante fermes laitières wallonnes (Théron et al., 2011). [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.

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 ▲]

Les agriculteurs sont les principaux architectes du milieu rural wallon. En effet, ils assurent la gestion de près de la moitié de la superficie de la Wallonie. On observe néanmoins, depuis quelques années, une régression lente (3%/an) et constante de leur effectif. Confrontés à un contexte changeant, de plus en plus concurrentiel, les agriculteurs sont face à des choix stratégiques difficiles en vue d’optimiser l’efficience de leur exploitation. Pour y parvenir, ils doivent mener une réflexion globale de leur mode de production et intégrer tous les aspects assurant la durabilité de leur exploitation. Pour les aider dans cette démarche, une analyse de la durabilité de 90 exploitations « 100% Lait » (>95% de vaches laitières et pas de culture de rente) a été réalisée dans le cadre de DuraLait et de DuraLait Plus. Ces études sont subsidiées par la DGARNE, Direction de la Qualité. Les piliers économique et social de la durabilité ont été plus particulièrement étudiés dans ces projets. L’organisation du travail a été spécifiquement traitée car elle constitue un enjeu essentiel pour l’avenir de l’agriculture. En effet, les agriculteurs souhaitent soulager la pénibilité de leur travail. Dans un contexte économique difficile, cette dimension est essentielle pour envisager le maintien de l’agriculture dans notre région. Le présent article s’intéresse uniquement aux données relatives à l’organisation du travail. [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 ▲]

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.

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 ▲]

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 ▲]

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 ▲]

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 ▲]

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. Des constats sont tirés, des réflexions sont amenées, le débat est ouvert. [less ▲]

The research conducted during 2011-2012, on the Ezăreni farm, has sought influence of fertilization on the leaves/stems ratio, crude protein content (CP), neutral detergent fiber content (NDF), acid detergent fiber content (ADF) and relative feed value (RFV), of alfalfa (Medicago sativa L.) in the second and third year of vegetation, at the first cut. The studied experimental plots were v1- unfertilized (control plot), v2-N50P50, v3-N75P50 and v4-30 t/ha manure). The results showed that the fertilization negatively affected crude protein content of plants. Although the protein content of leaves was higher and that of strains was less affected, the leaves/stems ratio decided this indicator for plant production. Organic fertilization showed a highly significant positive effect on the content of plant leaves and stems in NDF and ADF. [less ▲]

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 ▲]

This study confirms that active MPO is associated with cellular fraction of the ejaculate, as previously suggested for total MPO concentration in thawed semen (2). However, active MPO concentrations were dramatically lower than total MPO concentrations observed in equine semen (3), which could be explained by presence of inactive MPO subunits in semen. MPO activity in sperm-rich pellet can be used as a predictive marker of post-thaw semen quality. Moreover, methods to inhibit MPO should be investigated in semen. [less ▲]

We then go on to describe some first results as well as a strategy for constraining mode identification. [less ▲]

This paper reviews recent case studies completed on landslides (and dams) with probable (post-) seismic origin or susceptible to seismic failure in the Tien Shan, Central Asia. The first investigation presented here was carried out in 2005 on the Kainama earthflow, mainly composed of loess, which occurred in April 2004 and killed 33 people. Geophysical and seismological were used to build a reliable 3D model of the geometry and properties of the subsurface layers. The paper will also present results from microseismic measurements on loess landslides in Tajikistan that partly have a seismic origin. They are located close to the area that was affected in 1949 by the M=7.4 Khait earthquake and the numerous landslides triggered during the event, including the Khait rock avalanche. [less ▲]

This paper presents a system that gives the illusion of a 3D immersive and interactive environment with 2D projectors. The user does not need to wear glasses, nor to watch a (limited) screen. The virtual world is all around him, drawn on the floor. As the user is himself immersed in the virtual world, there is no need for a proxy like an avatar; he can move inside the virtual environment freely. Moreover, the Isee-3D system allows a user to manipulate virtual objects with his own body, making interactions with the virtual world very intuitive. Giving the illusion of 3D requires to render images insuch a way that the deformation of the image projected on thefloor is taken into account, as well as the position of the user’s “eye” in its virtual world. The resulting projection is neither perspective nor orthographic. Nevertheless, we describe how thiscan be implemented with the standard OpenGL pipeline, without any shader. Our experiments demonstrate that our system is effective in giving the illusion of 3D.

Aquitards can be effectively parameterised and incorporated in a groundwater flow model by using standard cone penetration tests (CPTs). Several conceptually different realizations of an aquitard’s hydraulic conductivity field were evaluated based on: (i) conventional methods of soil behaviour type classification, (ii) recent relationships from the literature, and (iii) novel site-specific relations with hydraulic conductivity. We show that use of most of these CPT-based hydraulic conductivity estimations in groundwater flow modelling effectively enhance model performance based on absolute head values and gradients across the aquitard. Conceptual models that considered a spatially heterogeneous hydraulic conductivity for the aquitard performed better than the reference case with a uniform aquitard hydraulic conductivity. However, the hydraulic conductivity of thin heavy clay lenses, characteristic of the aquitard present in our study area, cannot be captured using these continuum approaches. The latter leads to a bias in the direct hydraulic conductivity predictions; an alternative is to invoke inverse modelling with the heterogeneous parameter fields. To address this issue, the concept of the boundary energy associated with the CPT signal is also introduced for characterising the presence of heavy clay lenses. Overall, the CPT-based concepts provide more accurate, robust, and high-resolution data-based parameterisation of the studied aquitard. [less ▲]

We consider the output regulation problem for linear systems subject to actuators saturation. A state-feedback unconstrained regulator is transformed into an error-feedback bounded regulator by introducing an observer which is then decomposed into the sum of "unconstrained" and "antiwindup" dynamics. The unconstrained dynamics are regulated towards a predefined reference trajectory, by a control signal u which may violate the saturation bounds during transients. The antiwindup dynamics transiently store the mismatch between unconstrained and constrained dynamics. The antiwindup design also applies to a predefined error-feedback dynamic regulator for the unconstrained system, as in standard antiwindup setting. As a particular case of distinct interest, the design provides a new global asymptotic stabilizer for saturated null-controllable systems. [less ▲]

Recent developments in router level topology discovery have suggested the introduction of IGMP probing in addition to standard techniques such as traceroute and alias resolution. With a single IGMP probe, one can obtain all multicast interfaces and links of a multicast router. If such a probing is a promising approach, we noticed that IGMP probes are subject to filtering, leading so to the fragmentation of the collected multicast graph into several disjoint connected components. In this paper, we cope with the fragmentation issue. Our contributions are threefold: (i) we experimentally quantify the damages caused by IGMP filtering on collected topologies of large tier-1 ISPs; (ii) using traceroute data, we construct a hybrid graph and estimate how far each IGMP fragment is from each other; (iii) we provide and experimentally evaluate a recursive approach for reconnecting disjoint multicast components. The key idea of the third contribution is to recursively apply alias resolution to reassemble disjoint fragments and, thus, progressively extend the mapping of the targeted ISP. Data presented in the paper, as well as reconstructed topologies, are freely available at http://svnet.u-strasbg.fr/merlin. [less ▲]

This work is part of a project that deals with the three-dimensional (3D) analysis of normal and pathological gaits based on a newly developed system for clinical applications, using low-cost wireless accelerometers and a signal processing algorithm. This system automatically extracts relevant gait events such as the heel strikes (HS) and the toe-offs (TO), which characterize the stance and the swing phases of walking. The performances of the low-cost accelerometer hardware and related algorithm have been compared to those obtained by a kinematic 3D analysis system and a force plate, used as gold standard methods. The HS and TO times obtained from the gait data of 7 healthy volunteers (147 trials) have been found to be (mean ± standard deviation) 0.42±7.92 ms and 3.11±10.08 ms later than those determined by the force plate, respectively. The experimental results demonstrate that the new hardware and associated algorithm constitute an effective low-cost gait analysis system, which could thus be used for the assessment of mobility in routine clinical practice.

In European standards, for Class 4 cross-sections, the Effective Width Method (EWM) must be used to account for the effect of local buckling. Because of the complexity of this method, other methods have been developed, such as the Direct Strength Method (DSM) for cold-formed thin-walled profiles and the Continuous Strength Method (CSM), initially established for members made of stainless steels. To a large extent, the CSM yield accurate predictions, especially in the low slenderness range where the current DSM design procedure tends to produce conservative results, for materials with pronounced strain hardening. The present paper presents an extension of the DSM which provides accurate strength predictions in the low slenderness range for stainless steel thin-walled section columns failing by distortional, local and overall buckling.
