[more ▼]This paper highlights technical and economic choices for rural electrification in Africa and presents the rationale for trigeneration in health and education applications. An archetypal load profile for a rural health clinic (25 kWh/day 118-139 kWht ) is described and a regional analysis is performed for sub Saharan Africa by aggregating NASA meteorological data for e.g. insolation, temperature, and heating and cooling degree days using correlates to latitude. As a baseline for comparison, the technical, economic (using discounted cash flow) and environmental aspects of traditional electrification approaches, Photovoltaic (PV) systems and diesel generators, are quantified and options for meeting heating and cooling loads (e.g. gas-fired heaters, absorption chillers, or solar water heaters) are evaluated alongside an emerging micro-scale Concentrating Solar Power (CSP) technology featuring a solar thermal Organic Rankine Cycle (ORC). Photovoltaics hybridized with LPG/Propane and μ-CSP trigeneration are the lowest cost alternatives for satisfying important but often overlooked thermal requirements, with cost advantages for μ-CSP depending on latitudinal variation in insolation and thermal parameters. For a 15-year project lifetime the net present cost for meeting clinic energy needs varied from 44-55k USD, with specific levelized electricity costs of 0.26-0.31 USD/kWh. Diesel generation is both costly and polluting (94 tons CO2 per site over 15 years), while LPG/Propane based heating and cooling results in 160-400 tons CO2 emittted. The comparative analysis of available technologies implies that where the energy demand includes a mixture of electrical and thermal loads, as in typical health and education outposts, μ-CSP trigeneration approaches are cost effective and a non-carbon emitting.

[more ▼]The concept of Community of Practice (CoP) takes nowadays a great part in the formal or informal learning domain. In addition, computerised tools are often used to sustain the activities of these communities (Wenger, White & Smith, 2009). The ÉduCoP case study deals with the creation and the animation process of a CoP that was launched in 2010 at the University of Liège. Initiated by a master student in educational sciences, it aims at developing and making durable a community of practice composed of learners in this field and supported by Information and Communication Technologies. This paper presents several actions undertaken to develop this CoP: the analysis of the potential members' needs, stakes and motivations of students to enrol in this project; the choice of useful and usable technological tools to provide them (here, the eGroupWare platform) and the training sessions linked to its efficient uses; the activities conducted to develop the CoP's members identity and to lead them to debate about common topics, to produce and share resources. The CoP's evolution was observed through qualitative and quantitative data collection processes (e.g. interviews about the members' implication and roles, support from animator, obstacles, feeling to belong to a CoP, analysis of the topics presented in the posted documents and messages, uses of the technological tools, frequency of connection...). The results are discussed here and perspectives are evoked for this CoP. If the actions undertaken show encouraging results, neverthless obstacles to the creation and the evolution of such a CoP have been identified (e.g. lack of technological culture among some members, reluctance to share personal productions). Some perspectives are considered to overcome these problems. Since October 2011, this initiative has been recognised at the institutional level: the university is interested in lessons learned in order to implement CoP into other faculties that would be willing to start networking and create communities of learners or of practice.

[more ▼]The scientific objectives of the ESA-NASA rover of the 2018 mission of the ExoMars Programme are to search for traces of past or present life and to characterise the near-sub surface. Both objectives require study of the rock/regolith materials in terms of structure, textures, mineralogy, and elemental and organic composition. The 2018 rover ExoMars payload consists of a suite of complementary instruments designed to reach these objectives. CLUPI, the high-performance colour close up imager, on board the 2018 ESA-NASA Rover plays an important role in attaining the mission objectives: it is the equivalent of the hand lens that no geologist is without when undertaking field work. CLUPI is a powerful, highly integrated miniaturized (<700g) low-power robust imaging system, able to operate at very low temperatures (-120°C). CLUPI has a working distance from 10cm to infinite providing outstanding pictures with a color detector of 2652x1768. At 10cm, the resolution is 7 micrometer/pixel in color. The focus mechanism and the optical-mechanical interface are a smart assembly in titanium that can sustain a wide temperature range. The concept benefits from well-proven heritage: Proba, Rosetta, MarsExpress and Smart-1 missions… Because the main science objective of ExoMars concerns the search for life, whose traces on Mars are likely to be cryptic, close up observation of the rocks and granular regolith will be critical to the decision as whether to drill and sample the nearby underlying materials. Thus, CLUPI is the essential final step in the choice of drill site. But not only are CLUPI's observations of the rock outcrops important, but they also serve other purposes. CLUPI, could observe the placement of the drill head. It will also be able to observe the fines that come out of the drill hole, including any colour stratification linked to lithological changes with depth. Finally, CLUPI will provide detailed observation of the surface of the core drilled materials when they are in the sample drawer at a spatial resolution of 15 micrometer/pixel in color. The close-up imager CLUPI on the ESA-NASA rover of the 2018 mission will be described together with its capabilities to provide important information significantly contributing to the understanding of the geological environment and could identify outstanding potential biofabrics (stromatolites...) of past life on Mars.

[more ▼]Introduction: Platelet-Rich Plasma (PRP) contains lot of growth factors which could enhance the healing process of different tissues. We aimed to determine if a single injection of PRP could improve the cicatrisation of ruptured Achilles tendons of rats. Material and Methods: A 5mm defect was surgically made in the Achilles tendon of 120 rats. A few hours after surgery, 45 rats received a PRP or PBS injection in situ. After 5, 15 and 30 days, 20 rats of both groups were euthanized and 15 collected tendons were immediately submitted to a biomechanical tensile strength test until rupture using a “cryo-jaw” device. After, theses samples were used for transcriptomic analyses. Histological and biochemical analyses were performed on the five remained tendons in each group. Results: Tendons in the PRP group were more resistant to rupture at 15 and 30 days than those in the control group. The transverse area of tendons in the PRP group was significantly higher at day 5 and 15. The constraint was significantly increased in tendons of the PRP group in the late phase of the healing (day 30). Histological and immunohistological analysis showed an increased staining for fibrillar collagen at day 5 confirmed by a biochemical analysis showing an increased collagen concentration in the callus. The expression of tenomodulin, a tenocyte differentiation marker, was significantly higher in the PRP-treated tendons at day 5. No significant difference in terms of mRNA for type III collagen and matrix metalloproteinase 9 was observed at any time between the 2 groups. Conclusion: A single injection of PRP in sectioned Achilles tendon of rats few hours after surgery influences the early phase of tendons healing, resulting in an ultimate stronger mechanical resistance.

[more ▼]Introduction: Tendinopathies, especially jumper’s knee, often remain rebel to conservative treatments. Several experimental studies have shown the healing properties of platelet and their growth factors. Researches have specifically demonstrated the platelets action as mediator and/or enhancer of tissue healing. The aim of our study was to investigate the effect of 1 injection of PRP in patients suffering from chronic jumper’s knee. Our protocol was approved by Ethic Committee of University and University Hospital of Liège. Methods: Patients performed imaging (US and MRI) and functional assessments, and a clinical examination using an algometer, before treatment and 6 weeks after PRP treatment. They were also invited to answer to questionnaire relative to pain and functional status. PRP was obtained from autologous blood using an apheresis system (COM.TEC, Fresenius). The injection of 6mL of PRP was realised without local anaesthesia into the proximal insertion of the patellar tendon. A 48h rest-time was recommended after infiltration. Afterwards, a submaximal eccentric reeducation was initiated 1 week after infiltration 3 times a week during 5 weeks. In case of pain, anti-inflammatory drugs were prohibited and patient were encouraged to take class I or II painbrakers. Results: At this time, 10 patients with jumper’s knee were included in our study. Pre-injection tests revealed pain of the upper part of the patellar tendon just below the patella, associated with loss of function. Imaging exams confirmed diagnosis. Six weeks post-injection, the clinical status was improved in all patients, with a significant decrease of algo-functional scores. The pain reported during functional assessments was decreased (in particular for the eccentric actions), yet no significant improvement of physical performances was observed. We found no significant differences between imaging exams before and 6 weeks after PRP injection. Conclusion: One in situ injection of PRP clinically improved patients with jumper’s knee 6 weeks after treatment. All the 10 patients reported a decrease of pain during day-life and through physical activities. However nor functional performances neither imaging were improved.

Different from previous research, which either uses a complicated mechanical model with a simple control system model, or vice versa, this paper studies the coupling of subsystems’ dynamics using a high-fidelity aeroelastic model of wind turbine and a detailed analytical model of control generating systems. A monolithic time integration approach is applied so that better numerical accuracy and stability are achieved. Control strategies on power optimization are discussed taking into account the influence of structural flexibility. Simulation examples are given on both stable and turbulent wind situation.

[more ▼]Material yielding on one hand and local buckling on the other hand limit the cross-section capacity of steel structural members. Current structural design codes use the concept of cross-section classification to determine the cross-section resistance of hot-rolled profiles. In this system, the Effective Width Method (EWM) is employed to account for local buckling effects for slender, class 4, cross-sections. Alternative design methods for treatment of local buckling in metallic cross-sections have been proposed, including the Direct Strength Method (DSM), developed for cold-formed steel structural profiles, and, recently, the Continuous Strength Method (CSM). The DSM is based on the assumption that the strength can be predicted from the ratio of the yield strength to the elastic critical load in conjunction with a strength curve for the entire cross-section. Thus it is essentially an extension of the use of column curves for global buckling, but with application to local buckling instability. The CSM is a deformation-based design approach which is based on a continuous relationship between cross-sectional slenderness and cross-section deformation capacity and a rational exploitation of strain hardening. This paper is focused on the evaluation of the cross-sectional resistance of hot-rolled structural profiles. Test data from literature experimental programmes have been gathered and analysed to compare the predictions from the DSM and CSM design approaches.

[more ▼]Finite element models accurately compute the mechanical response of bone and bone-like materials when the models include their detailed microstructure. The aim of this paper is to develop and validate a biomechanical model for deer antler cancellous bone tissue based on X-ray microtomographic images. In order to simulate the mechanical behavior under compressive load using a finite element model, images obtained by X-ray microtomography were exported into Metafor, which is an non-linear finite element software initially developed at University of Liège for metal forming processes. This software has recently found biomedical applications. The ultimate goal is to compare model predictions with the mechanical behavior observed experimentally using the Skyscan material testing stage under compression mode. The creation of the biomechanical model mesh from segmented μCT images, its integration into the software Metafor and the simulation of a compression test are described in this paper.

[more ▼]Nowadays, EU shipyards that are facing difficulties due to the global crisis are often trying to diversify their activities. Some of them have already turned to the production of offshore windmill components. The installation and operation of offshore windmills are much more complex than onshore due to the distance and the depth of the water column. This creates problems specific to the production, installation and maintenance of offshore wind turbines. A tool for sequencing and installation simulation has been developed to assess the risks associated to the assembly of wind turbines parks via simulations of the different phases of construction considering various random phenomena such as weather conditions and uncertainties on production time.

[more ▼]Background: The metabolic and cardiac impact of a cycling effort on blood biology is not very well described in the literature. We aimed to measure the concentration of different biomarkers (cardiac and metabolic) released during an international cycling race. Materials and Methods: Venous blood samples of 15 young men (25.1 ± 6.4 y.o.) were collected just before (T1), just after (T2), 3 hours (T3) after an international cycling race of 176 kilometers in Belgium for the determination of cardiac and metabolic biomarkers: red blood cells (RBC) haemoglobin (HgB) creatinin (Cr) highly sensitive troponin T (hsTnT) myoglobin (MYO) NT-proBNP All automated assays were performed according to the manufacter’s specifications. For the statistical analysis, an Anova calculated with the Statistica Software version 9.1 was used. Results: •RBC and HgB levels varied significantly between T0 and T3 (respectively p=0.0026, and p=0.002) (Fig. 1 and 2). • Cr concentration also varied significantly between all times (T0-T1:p<0.0001, T1-T3:p=0.0326 and T0-T3 p=0.0001)(Fig.3). These changes might be related to renal flow depletion during exercise. •MYO increased significantly between T0 and T1 (p<0.0001), but quickly decreased between T1 and T3, however the T3 level stay higher than T0 (p=0.014) (Fig.4). •The stress delivered from the physical activity performed during the race induced a significant variation of hsTnT which increased significantly between T0 and T1 (p<0.0001) and stayed higher 3 hours after the end of the exercise (T0-T3: p<0.0001) (Fig.5) . •The intense exercise delivery by the race induced a significant variation of NT-proBNP, that followed the same kinetic of hsTnT but in smaller proportion. We noticed variations statistically significant between T0 and T1 and between T0 and T3 for NT-proBNP (Fig.6). •These increases of cardiac biomarkers were significant but reasonable and could not allow us to talk about cellular necrosis or irreversible injury. Conclusions: Our results show that stress generated by a cycling race could be the cause for the different metabolic variations observed. Troponin T stays without a doubt the most specific marker for stress related to myocardial tissue. Its increase can then be considered as being of interest.

However, the space complexity of tree ensembles, in terms of their total number of nodes, is often prohibitive, specially in the context of problems with very high-dimensional input spaces.

We show experimentally that preserving or even improving the model accuracy while significantly reducing its space complexity is indeed possible.

DISco allows multi-agent identification of anomalous situations (challenges) and assists coordinated remediation that will maintain service at an acceptable level, although degraded. The history of agents decisions, their context and outcomes is tracked as the situation evolves, and information is automatically gathered and organised to ease further human-assisted diagnosis. We then explore the feasibility of using state of the art peer-to-peer publish/subscribe and storage systems as building blocks for this service. The ability of those systems to support range queries and aggregation will be a key factor for their suitability to the task.

Une enquête de terrain combinée aux propriétés physico-chimiques des pesticides, a permis d’identifier la pression polluante agricole liée aux propriétés des pesticides et aux activités anthropiques. La sensibilité des sols au transfert des pesticides vers les eaux de surface et souterraines a été évaluée sur base, d’une part d’une approche par modélisation mécaniste, et d’autre part à partir de l’exploitation de l’information qualitative de la carte des sols, jugée pertinente et non explicitement valorisée par le modèle mécaniste. L’évaluation du risque global a ensuite été réalisée à partir de la construction d’un système expert basée sur la logique floue, qui intègre les évaluations spécifiques aux propriétés des pesticides, aux pratiques culturales et à la sensibilité des sols au transfert des pesticides vers les eaux, en tant que milieu transit-vecteur. L’approche par « logique floue » est un outil robuste qui permet notamment d’agréger de façon uniforme des informations de sources variées, mais aussi d’intégrer l’incertitude (imprécision) associée à certaines données, telles que celles liées aux caractéristiques physico-chimiques des pesticides ou des sols.

[more ▼]The Ets factors are a family of 27 transcription factors characterized by their unique DNA-binding domain, the ETS domain. We aimed at building a protein-protein interaction (PPI) map (interactome) of the human Ets factors in order to better define their roles and regulations in normal and oncogenic processes. The Ets interactome was built on a high-throughput yeast-two hybrid (Y2H) approach, and a literature and database curation of confident interactions which led us to the identification of 602 PPIs and 369 different protein partners. Clusterization using the Network Analysis Tool box (NeAT) divided the ETS interactome into 39 functional sub-networks. Among these, we identified Cluster16 as highly connected to the Erg ETS subfamily. A gene ontology (GO) enrichment analysis revealed that Cluster16 was associated to various aspects of mRNA processing. We therefore hypothesized that Erg factors might have a role in post-transcriptional gene regulation. This would constitute a entirely new and undisclosed role for ETS factors, which are so far firmly established as transcription factors. In support of our hypothesis, we observed that ERG localized in p-bodies, cytoplasmic sites of mRNA decay. Interestingly, under various cellular stresses, a portion of ERG and its partners from Cluster16 localized in stress granules, cytoplasmic sites of mRNA silencing physically linked to p-bodies. Hence, we hypothesized that Erg proteins might be involved in cellular mRNAs degradation. To test this, we performed a MS2-based tethering assay and showed that the recruit-ment of Erg factors promoted degradation of a reporter mRNA, mainly via its N-ter domain. Very importantly, oncogenic TET-Erg fusions described in AML and Ewing’s sarcoma exhibited diminished ability to degrade target mRNAs, concomitantly with the loss of the N-ter domain of the corresponding Erg protein. This re-inforces the important role of Erg proteins in mRNA degradation in cancer. Our efforts are now concentrated on identifying the molecular determinants behind this new function of Erg proteins.

[more ▼]In Senegal, family businesses are present in all industries and represent a significant force. Most of family entrepreneurs are between 40 and 50 years old, which show that they will soon face the challenge of transmission. To face this challenge and thus to ensure their continuity, it is necessary to ensure the cohesion of family ties, particularly through the family governance. So, our contribution aims, in a contingent perspective and based on a large survey of the existing literature, to a better appraisal of family businesses in Senegal through a better understanding of their family governance practices first, and by understanding the role of family governance on their global performance in order to identify key success factors for a successful family transmission process in the context of Senegal.

Two new hypotheses integrating recent researches on offender’s behaviour are proposed to broaden the applicability of the techniques of geographic profiling to commuters and irregular patterns of crimes. The journeysto- crime variance and place attractiveness will be successively integrated in GP methods. In order to evaluate the variance of the journeys-to-crime on real road network, a method based on least square adjustment in raster mode is developed. A real case of serial rapes illustrates the effectiveness of those assumptions for a non-uniform pattern of crimes.

[more ▼]Selective laser melting (SLM) and laser cladding were developed in the late 1990s as economic layer-by-layer near-net-shape processes allowing for the production – and also, in the case of laser cladding, the restoration - of complex parts. Both techniques involve the melting of a metallic powder with a laser. In the case of SLM, the metallic powder is deposited layer by layer and then molten locally according to the desired shape, whereas in laser cladding the metallic powder is projected onto a substrate through a tube coaxial with the laser. In both processes, the metallic melt pools then cool down and solidify very rapidly, thus producing strongly out of equilibrium microstructures that might exhibit high internal stresses. In the present work, efforts have been made to enhance the flexibility of the laser cladding process: a second laser with a maximum power of 300W was installed beside the original laser (with a higher maximum power of 2000W), thus allowing for the processing of parts with thinner walls and/or coatings. Moreover, flexibility was also improved in relation with the geometry of the parts by use of a 5-axes displacement control. Samples of alloy Ti-6Al-4V, that is widely used in the aeronautic industry due to its high specific strength, have been processed both by SLM and by laser cladding. The resulting microstructures have been characterised in details by optical microscopy, SEM and EBSD so as to allow for a better understanding of the solidification process and of the subsequent phase transformations taking place upon cooling for both techniques. The influence of processing parameters such as the orientation of the deposition of the successive powder layers on the mechanical properties was also investigated by means of uniaxial tensile testing performed on samples with different deposition orientations in regard to the direction of mechanical solicitation. Moreover, some of the samples for mechanical testing had undergone an annealing treatment at 640°C for 4 hours to relieve internal stresses, in order to assess more precisely the effect of those stresses on the tensile properties.

[more ▼]As network link rates are being pushed beyond 40 Gbps, IP lookup in high-speed routers is moving to hardware. The TCAM (Ternary Content Addressable Memory)-based IP lookup engine and the SRAM (Static Random Access Memory)- based IP lookup pipeline are the two most common ways to achieve high throughput. However, route updates in both engines degrade lookup performance and may lead to packet drops. Moreover, there is a growing interest in virtual IP routers where more frequent updates happen. Finding solutions that achieve both fast lookup and low update overhead becomes critical. In this paper, we propose a hybrid IP lookup architecture to address this challenge. The architecture is based on an efficient trie partitioning scheme that divides the Forwarding Information Base (FIB) into two prefix sets: a large disjoint leaf prefix set mapped into an external TCAM-based lookup engine and a small overlapping prefix set mapped into an on-chip SRAM-based lookup pipeline. Critical optimizations are developed on both IP lookup engines to reduce the update overhead. We show how to extend the proposed hybrid architecture to support virtual routers. Our implementation shows a throughput of 250 million lookups per second (MLPS). The update overhead is significantly lower than that of previous work and the utilization ratio of most external TCAMs is up to 100%.

[more ▼]During the last few years, several piano key weirs (PKWs) have been built in France by Electricité de France (EDF). Thanks to the reduced footprint and high release capacities of this new type of weir, making it particularly suited for concrete dams rehabilitation, lots of other projects in varied countries are under construction or study. The prototype use of PKW requires knowledge about its structural behaviour, hydraulic capacities as well as integration into dams’ environment. This paper aims at presenting numerical and physical modelling works performed at the University of Liege to address the last two points. In particular, large scale physical modelling and parametric scale models enabled to understand the hydraulic behaviour of the structure and to highlight its main geometric parameters as well as their best variation interval depending on various criteria related to the weir design (discharge efficiency, cost…). A 1D numerical model has also been developed based on these experimental investigations. It enables to predict in a few minutes, with 10% accuracy, the discharge capacity of a given PKW geometry on its usual operation head range. This model, available as a freeware on http://www.pk-weirs.ulg.ac.be, constitutes a key tool for the first design of such weirs. Finally, the scale model studies of major projects such as Raviège dam (France) for EDF and Ouldjet Mellegue Project (Algeria) for Coyne et Bellier – Tractebel Engineering enable to confront theoretical predictions with experimental results and to address the problem of PKW integration on dam crests.

The development of a non-linear analogue of linear modal analysis is therefore an important endeavor. The objective of this paper is to show that nonlinear normal modes (NNMs) represent a useful and practical tool in this context. A full-scale spacecraft structure is considered and is modeled using the finite element method. Its NNMs are computed using advanced numerical algorithms, and the resulting dynamics is then carefully analyzed. Nonlinear phenomena with no linear counterpart including nonlinear modal interactions are also highlighted. [less ▲]Detailed reference viewed: 61 (13 ULg) 4.

[more ▼]Introduction Pregnancy is associated with various physiological changes that essentially affect musculoskeletal conditions in the mare. However, the influence of pregnancy on equine bone metabolism has not been studied to great detail. Aim of this study was to evaluate the effect of pregnancy on bone turnover markers in clinically normal lactating mares. Materials and Methods Venous blood samples were collected three-times from 17 multiparous lactating Haflinger mares, aged four to 18 years, during the first (T1), second (T2) and third (T3) trimester of pregnancy. Blood creatinine and gamma glutamyl transferase (GGT) values were evaluated. Serum concentrations of osteocalcin and carboxy-terminal cross-linking telopeptide of type I collagen (CTX-I) were determined using an equine specific osteocalcin radioimmunoassay and an automated CTX-I electrochemiluminescent sandwich antibody assay. Results All mares had normal creatinine and GGT values. Serum CTX-I values significantly increased during the last trimester of pregnancy. Serum osteocalcin concentrations were lowest at T2 and increased thereafter at T3. Conclusions Changes in bone turnover seem to depend on the stage of pregnancy in multiparous mares. Highest values of serum CTX-I and osteocalcin were obtained in the last trimester of pregnancy.

The experimental field was equipped with an eddy covariance system that measured CO2 fluxes and with a micrometeorological station. Carbon exported through mowing, imported through compost application or through complementary feeds for cattle was also measured. Carbon lost through CH4 emissions was finally estimated, allowing the establishment of a full C budget. In addition, the vegetation development was followed in order to estimate herbage production and dry matter intake by grazing animals. First year full carbon budget is presented and discussed, in relation with climate conditions and management practices.

At day 102 of gestation, at farrowing and at weaning, backfat thickness of the sows was determined. The total number of piglets, the number of piglets born alive, stillborn and dead during the suckling period and the duration of gestation were measured. At birth as well as 24 hours, 14 days and 28 days (weaning) later, the piglets were weighed individually. Colostrum samples were collected at farrowing and 24 hours later for the determination of IgG and IgA contents and the fatty acid profile. Neither performance parameters of the sows nor IgG and IgA concentrations in colostrum were affected by the different dietary treatments. This was probably due to the short duration of trial period in which the oil supplements were administered. However, the colostral fatty acid profiles reflected very well the profiles of the supplemented oils. Furthermore, the different treatments affected the growth performances of the piglets. At weaning, the piglets from the FO treatment were respectively 263 and 329 g heavier than the piglets from the SO and CO treatments (P < 0.05). This corresponded to 4.2 % and 5.8 % increase of the ADG in comparison to the SO and CO treatments, respectively. These results show the importance of the fatty acid composition in colostrum on the performances of piglets and consequently the importance of the feeding of sows at the end of gestation.

[more ▼]We propose a learning approach to pre-compute K-armed bandit playing policies by exploiting prior information describing the class of problems targeted by the player. Our algorithm ﬁrst samples a set of K-armed bandit problems from the given prior, and then chooses in a space of candidate policies one that gives the best average performances over these problems. The candidate policies use an index for ranking the arms and pick at each play the arm with the highest index; the index for each arm is computed in the form of a linear combination of features describing the history of plays (e.g., number of draws, average reward, variance of rewards and higher order moments), and an estimation of distribution algorithm is used to determine its optimal parameters in the form of feature weights. We carry out simulations in the case where the prior assumes a ﬁxed number of Bernoulli arms, a ﬁxed horizon, and uniformly distributed parameters of the Bernoulli arms. These simulations show that learned strategies perform very well with respect to several other strategies previously proposed in the literature (UCB1, UCB2, UCB-V, KL-UCB and $\epsilon_n$-GREEDY); they also highlight the robustness of these strategies with respect to wrong prior information.

[more ▼]Estimating the orientation of the observed person is a crucial task for home entertainment, man-machine interaction, intelligent vehicles, etc. This is possible but complex with a single camera because it only provides one side view. To decrease the sensitivity to color and texture, we use the silhouette to infer the orientation. Under these conditions, we show that the only intrinsic limitation is to confuse the orientation q with the supplementary angle (that is 180°-theta), and that the shape descriptor must distinguish between mirrored images. In this paper, the orientation estimation is expressed and solved in the terms of a regression problem and supervised learning. In our experiments, we have tested and compared 18 shape descriptors; the best one achieves a mean error of 5:24°. However, because of the intrinsic limitation mentioned above, the range of orientations is limited to 180°. Our method is easy to implement and outperforms existing techniques.

[more ▼]Estimating the pose of the observed person is crucial for a large variety of applications including home entertainment, man-machine interaction, video surveillance, etc. Often, only a single side view is available, but authors claim that it is possible to derive the pose despite that humans evolve in a 3D environment. In addition, to decrease the sensitivity to color and texture, it is preferable to rely only on the silhouette to recover the pose. Under these conditions, we show that there is an intrinsic limitation: at least two poses correspond to the observed silhouette. We discuss this intrinsic limitation in details in this short paper. To our knowledge, this issue has been overlooked by authors in the past. We observe that this limitation has an impact on the way previous reported results should be interpreted, and it has clearly to be taken into account for designing new methods.

[more ▼]Non linear normal modes offer a rigorous framework, both mathematical and physical, for theoretical and experimental dynamical analysis. Albeit still in its infancy, the concept of non linear normal modes has the potential of providing to both the academic and the industrial establishment a powerful tool for the analysis of non linear dynamical systems. However, in order to exploit the full potential of this theory (and its associated simulation capability), there is need to integrate it with other branches of non linear structural dynamics: namely, in order for the non linear normal modes of a real - physical - structure to be computed, there is need to identify and quantify its non linearity. In this paper, an identification method based on the measured Frequency Response Function (FRF) is employed to identify and quantify the system's non linearity before computing the system's non linear normal modes.

[more ▼]Créée en 1997 dans l'esprit du modèle québécois, l'ASBL Parlement Jeunesse de la Communauté française organise annuellement une simulation parlementaire à destination de jeunes francophones résidants en Belgique, âgés de 17 à 26 ans. Cette initiative citoyenne permet ainsi à une centaine de jeunes, idéalement issus de tous milieux et de tous horizons, de découvrir les rouages internes de la démocratie, conformément aux mécanismes et procédures propres au système parlementaire belge. Là où nombre d'études scientifiques sur l'engagement politique des jeunes s'accordent sur la prévalence d'un désintérêt manifeste et – plus largement – sur une tendance générale au déclin de l'engagement politique chez les jeunes, l'action citoyenne mise en œuvre par le Parlement Jeunesse témoigne en réalité de l'existence de formes moins classiques – dans le cas présent, associative – de socialisation des jeunes à la « chose politique ». L’objectif général poursuivi dans cette contribution est d'identifier la nature et les fondements de l'engagement politique déployé à travers cette jeune initiative, ainsi que d’en mesurer la portée et les limites. Dès lors, en quoi le Parlement Jeunesse participe-t-il de l’engagement politique des jeunes ? Ne contribue-t-il qu’au renforcement d’un intérêt politique latent et préexistant ? A contrario, participe-t-il de la construction d’un engagement politique au départ d’un processus d’apprentissage pratique des rouages de la démocratie parlementaire ? En d’autres termes, quelles sont les forces et les faiblesses de cette initiative citoyenne en terme de socialisation politique de la jeunesse ?

[more ▼]A method has been designed to test the retention of drops generated by a moving agricultural nozzle using high speed imaging both on synthetic and leaf surfaces. The method allows a precise investigation of spray retention by a characterisation of impact speed, drop diameter and impact behaviour. The paper presents a comparison of the spray behaviour on the synthetic surface with the behaviour on outdoor grown wheat leaves fixed on a microscope slide. Target surfaces were horizontal. A range of surface tension was tested using the tank-mix adjuvant Break-Thru S240 at different concentrations in distilled water. Results show the relevance of a synthetic surface for use as reference for the assessment of spray application efficiency. The drop behaviour on the superhydrophobic slide was representative of difficult-to-wet leaves surfaces. The reference surface avoids the natural variability of leaves and is therefore more suited to conduct comparative assessment of formulation retention performance.

[more ▼]A solver has been developed within the OpenFoam framework to compute large amplitude motion of two-dimensional rigid configurations. The results obtained with this code were successfully validated on rigid airfoils at static and dynamic conditions, as well as correlated with experimental data and numerical solutions from similar unsteady solvers. The results demonstrate that current computational methods are, within the constraints imposed by spatial grids, temporal integration and turbulence modeling, capable of capturing the self-sustained oscillations characterizing stall flutter event with reasonable accuracy, including the mechanisms of energy transfer.

[more ▼]Urban sprawl has been identified as a major issue for sustainable development. Energy consumption in suburban buildings, in particular, is a widespread issue because detached types of houses require significantly more energy to be heated than more compact urban forms. Energy efficiency is often presented as a viable approach to the mitigation of climate change, but research and studies mainly contend with individual buildings and do not address this issue at larger territorial scales or for a whole building stock. In this respect, this paper first presents a morphological definition of urban sprawl. This definition uses territorial and cadastral data available for the Walloon region of Belgium. Using this definition, a suburban type classification adapted to thermal studies is drawn up. A representative block of each type is selected to model energy use and to determine the total energy consumption of the whole suburban building stock. An application is then presented concerning a comparison of potential energy savings associated with several renovation strategies. The results of this exercise are presented and highlight the benefits of combining Geographic Information Systems (GIS) tools, territorial data and thermal simulations for the efficient energy management of suburban areas at the scale of the whole building stock.

[more ▼]Many nonlinear system identification methods have been introduced in the technical literature during the last thirty years. However, few of these methods were applied to real-life structures. In this context, the objective of the present paper is to demonstrate that the Restoring Force Surface (RFS) method can provide a reliable identification of a nonlinear spacecraft structure. The nonlinear component comprises an inertia wheel mounted on a support, the motion of which is constrained by eight elastomer plots and mechanical stops. Several adaptations to the RFS method are proposed, which include the elimination of kinematic constraints and the regularization of ill-conditioned inverse problems. The proposed methodology is demonstrated using numerical data. [less ▲]Detailed reference viewed: 54 (11 ULg) A finite volume based data transfer method for remeshing.

[more ▼]The resolution of many nonlinear solid mechanical problems with the Finite Elements Method requires remeshing when very large deformations occur. The remeshing operation is divided into two parts: the generation of the new mesh and the data transfer from the old to the new mesh. In dynamic plasticity problems, two kinds of fields have to be transferred: the first is defined thanks to the nodal values and the second one is defined at the integration points. These two kinds of fields are transferred thanks to an original computation of the Data Transfer Method based on the Finite Volume Elements. This method is compared to another one using Mortar Elements to solve metal forming problems.
