Le voyage au centre de la Terre a été magistralement imaginé par Jules Verne en 1864 avant de devenir un véritable topos de la littérature populaire et de jeunesse. Sa postérité s’illustre dans les multiples déclinaisons de la terre creuse, recensées notamment par Guy Costes et Joseph Altairac dans leur bibliographie commentée en 2006. En quoi ce motif plus communément associé à une atemporalité (monde perdu, histoire secrète) ou à une régression temporelle (monde sauvage, vie des cavernes) intervient-il aussi dans une écriture de l’anticipation ? Chez Verne lui-même, il s’agit à la fois d’un voyage à rebours dans le temps, chaque strate parcourue correspondant à un recul historique, et d’une expédition scientifique déployant une technologie et des connaissances novatrices. Ce motif topique semble donc porteur d’une ambiguïté temporelle féconde. La communication proposera un parcours transversal dans le corpus d’anticipation francophone allant d’Ignis (1883) de Didier de Chousy qui traite de l’exploitation d’une nouvelle énergie géothermique, le « feu central de la Terre », jusqu’à Régis Messac dont La Cité des Asphyxiés (1937) dépeint un monde intra-terrestre dystopique. Les reprises de la terre creuse permettent d’éclairer l’importance des filiations génériques, des supports partagés et des formules éditoriales à succès, mais elles mettent aussi en évidence des œuvres atypiques, traduisant de manière spécifique le discours social et scientifique de leur époque. Si Verne, ses épigones et d’autres auteurs d’anticipation ont pu être tentés de réinvestir la terre creuse en fiction à un moment où sa réalité n’est plus perçue comme crédible dans le champ scientifique, c’est sans doute en raison de l’intrication particulièrement dense des disciplines concernées (géographie, géologie, paléontologie, sciences naturelles) et de l’importance des idéologies qui ont pu les croiser et les dynamiser : positivisme, hygiénisme, colonialisme, craintes écologiques. Cette communication voudrait montrer comment le motif fécond de la terre creuse, dans son évolution complexe du plausible à l’irréel, passe d’une croyance à une théorie scientifique avant de se développer en chronotope littéraire.

While the combination of warmer and drier mean climatic conditions can have severe impacts on ecosystems, extreme events like droughts or heat waves that break the gradual climate change can have more long-term consequences on ecosystem composition, functioning and carbon storage. Hence, it is essential to assess the changes in climatic variability and the changes in frequency of extreme events projected for the future. Ecosystems could not be in a condition to adapt to these new conditions and might be disrupted. Here, the process-based dynamic vegetation model CARAIB DVM was used to evaluate and analyze how future climate and extreme events will affect European ecosystems. To quantify the uncertainties in the climatic projections and in their potential impacts on ecosystems, the vegetation model was driven with the outputs of different regional climatic models (RCMs), nested in CMIP5 GCM projections for the EURO-CORDEX project. We used the ALADIN version 5.3 (Météo-France/CNRM) and other EURO-CORDEX RCMs. These climatic projections are at a high spatial resolution (0.11-degree, ~12 km). CARAIB simulations were performed across Europe over the historical period 1951-2005 and the future period 2006-2100 under RCP4.5 and RCP8.5 emission scenarios. We simulated a set of 99 individual species (47 herbs, 12 shrubs and 40 trees) representing the major European ecosystem flora. First, we analyzed the climatic variability simulated by the climatic models over the historical period and compared it with the observed climatic variability. None of these climatic models can reproduce accurately the present natural climatic variability. Then, to assess the risk of ecosystem disruption in the future and to identify the vulnerable areas in Europe, we created an index combining several CARAIB outputs: runoff, mean NPP, soil turnover, burned area, appearance and disappearance of species. We evaluated the severity of change projected for these variables (period 2071-2100) relative to their current variability (period 1961-1990). Mean changes were considered severe if they exceed observed variability. The highest values of the index were found in southern Europe, indicating that the amplitude of the expected ecosystem changes largely exceeds current interannual variability in this area. [less ▲]

Fama and French risk premiums do not reliably estimate the magnitude of the size or book-to-market effects, inducing many researchers to inflate the number of factors. We object that controlling ex ante for noise in the estimation procedure enables to keep a parsimonious set of factors. We replace Fama and French’s independent rankings with the conditional ones introduced by Lambert and Hübner (2013). This alternative framework generates much stronger “turn-of-the-year” size and “through-the-year” book-to-market effects than conventionally documented. Furthermore, the factors deliver less specification errors when used to price portfolios, especially regarding the “small angels” (low size – high BTM stocks). [less ▲]

On the 13th March 2009, Belgium’s French Community (currently named the Wallonia-Brussels Federation (WBF)) parliament, adopted the “décret mémoire” (decree of remembrance). This deed shows Belgian public authorities’ will to mark their presence in the memorial field. The decree organizes the recognition and the financing of multiple actors and institutions by the authorities, through a structure and a hitherto unseen way of functioning. Among its activities, the decree organizes yearly calls for projects, whose recipients are non-profit-making organizations and educational institutions that are either organized or subsidised by the WBF. The organisation set in place by the decree of remembrance appears to be a “political use of the past”. That means that some past events are chosen and promoted to give meaning to the individual memory, in a collective intent. This way of doing comes from the political will to organize the representation of one common past, aiming to bring out themes that carry particular values. Consequently, is it possible to study the power that the decree actually gives to the public authorities? Does it allow them to constrain or to influence other actors of their memory field? If that is the case, how could it be possible to demonstrate it? We suggest trying to find an answer to these interrogations through a case study concerning the 2014 calls for projects of the year.

Organocobalt(III) with acetylacetonate ligands is the most representative example of R-Co bearing a weak C-Co bond that can release alkyl radicals under mild experimental conditions without requiring a photoactivation. The unique isolated specimen is a short oligo(vinyl acetate) end-capped by Co(acac)2. The high lability of the C-Co bond of this R-Co combined to the unique capacity of Co(acac)2 to reversibly trap alkyl radicals make this organocobalt unique for the precision synthesis of unprecedented polymers by the so-called Cobalt-Mediated Radical Polymerization (CMRP) technique. The growth of unstabilized and highly reactive growing radicals formed by the addition of R· to unconjugated olefins (vinyl esters, vinyl amides, vinyl imidazolium, vinyl chloride, ethylene) is controlled by the reversible formation of a weak C-Co bond at the polymer chain end. The lack of alternatives to this R-Co, especially to the structure of the alkyl group, has placed limitations on further innovation in (macro)molecular design. Other functional variants that would enable attractive chain-end derivatizations are unfortunately not available. In this communication, we will address this important challenge by describing an innovative synthetic route towards the preparation of a new functional R-Co(acac)2 that are characterized by a weak C-Co bond. We will report the conditions required for initiating and controlling the radical polymerization of various monomers from these R-Co. We will also demonstrate their utility for the production of novel telechelic polymers under mild experimental conditions, syntheses that can be carried out in water. [less ▲]

A point cloud is the output data of many sensors, such as Lidar and laser scanners, or the processing output from photogrammetry and SFM reconstructions. It is a 3D spatial representation of the environment through thousands, million or billions of points, where each single point as a position in space (X, Y, Z) It is safe to say that today, the technology is ready, and enable us to digitize very quickly the world as it stands. This RAW data is rapidly growing with the autonomous vehicles mapping our roads (LiDAR system equip it) and the robotics field using sensors to evolve in the environment. But how do we use this data? Professionnals have been struggling with point cloud, or delivering it to a client because it looks nice, but is there a real added value to visualization only?

Passive acoustics can offer inexpensive, non-invasive and no-destructive means of assessing temporal and spatial patterns in the distribution of individuals engaging in calling. In marine environments, passive acoustic recording methods can be used at depths not accessible to humans, independent of weather conditions, and for a long term. However, these studies have often restricted their investigations to the monitoring of one or two aquatic species. One reason of this loss of information is quite easy to explain: most of the sounds can be detected but cannot be identified. In many families, calling abilities are described in one or two species only although the descriptions of sound producing mechanisms have highlighted other members should be able to make sounds. Since 50 years, sounds were for example described in more or less 40 pomacentrid species but all the 392 species should be able to make sounds. This situation can be more complicated since some species are able to make different kinds of sounds according to the behavioural context. Some call characteristics can also be modulated according to the size in some species only. It shows an important amount of work has to be done to be able to understand the reef soundscape and to develop call recognition software system. [less ▲]

Les législations française et belge sur les accidents du travail constituent des ruptures déjà largement explorées, principalement sur le versant de leur laborieuse genèse. Les recherches sont bien moins développées à propos de leur mise en œuvre concrète. Comment les différents acteurs chargés de leur application – juges civils/de paix, médecins, avocats, assureurs, syndicats – autant que les victimes ont-ils expérimenté ce nouveau cadre légal ? Par un retour prioritaire aux sources judiciaires, cette contribution entend explorer ce processus d’apprentissage en mettant l’accent sur les principales difficultés rencontrées, sur les enjeux nouveaux et sur les réponses apportées au cours des années d’entrée en vigueur de la loi. À titre comparatif, les mêmes types de sources seront examinées pour une période tenue pour plus routinière (c. 1928-1930), de manière à mettre en évidence certaines des solutions retenues après la phase d’apprentissage, tout en soulignant, le cas échéant, les problèmes pendants ou nouveaux.

Pumped Storage Hydroelectricity (PSH) is a good alternative to increase the efficiency of power plants, which cannot regulate the amount of electricity generated according to the demand (wind, solar or even nuclear power plants). PSH plants, which consist in two reservoirs located at different heights (upper and lower), can store energy during low demand periods (pumping water from the lower to the upper reservoir) and generate electricity during the high demand peaks (falling water from the upper to the lower reservoir). Given that the two reservoirs must be located at different heights, PSH plants cannot be constructed in flat regions. Nevertheless, in these regions, an alternative could be to use abandoned underground works (open pits or deep mines) as lower reservoirs to construct Underground Pumped Storage Hydroelectricity (UPSH) plants. To select the best place to construct a plant, two considerations must be taken into account regarding the interaction between UPSH plants and groundwater: 1) the alteration of the natural conditions of aquifers and 2), the efficiency of the plant since the electricity generated depends on the hydraulic head inside the underground reservoir. Obviously, a detailed numerical model must be necessary before to select a location. However, a screening methodology to reject the most disadvantageous sites in a short period of time would be useful. Groundwater flow impacts caused by UPSH plants are analyzed numerically and the main variables involved in the groundwater evolution are identified. The most noticeable effect consists in an oscillation of the groundwater. The hydraulic head around which groundwater oscillates, the magnitude of the oscillations and the time to achieve a “dynamic steady state” depend on the boundaries, the parameters of the aquifer and the characteristics of the underground reservoir. A screening methodology is proposed to assess the main impacts caused in aquifers by UPSH plants. Finally, the efficiency regarding the groundwater evolution inside the reservoir is determined.

Since a few years, it has become possible to observe the development of cyber parties in western democracies. Their intensive use of internet to coordinate relations between members is supposed to attract new types of militant, interested by less hierarchical informal networks and sporadic political activities. Yet, the following question remains: What role(s) does the Internet play in the enrolment process within this kind of parties? Analyzing fifteen in-depth interviews with Belgian Pirate Party’s members as well as members’ online activities, this paper shows that it is possible to distinguish two kinds of cyber parties’ members. On the one side, some members are passionate about information and communications technology and their party membership is their sole political activity. On the other side, some members are more distant users of the Internet and are active in plenty of postmodern political associations. These two divergent militant profiles are key elements to explain the divergence of views among Belgian Pirate Party’s members, but also the relative lack of political visibility of this political party due to difficulties in achieving coordination.

Power can be performed by a system driven by a potential difference. From a given potential difference, the power that can be subtracted is constraint by the Carnot limit, which follows from the first and second laws of thermodynamics. If the system is such that the flux producing power (with power being the flux times its driving potential difference) also influences the potential difference, a maximum in power can be obtained as a result of the trade-off between the flux and the potential difference. This is referred to as the maximum power principle. It has already been shown that the atmosphere operates close to this maximum power limit when it comes to heat transport from the Equator to the poles, or vertically, from the surface to the atmospheric boundary layer. To reach this state of maximum power, the effective thermal conductivity of the atmosphere is adapted by the creation of convection cells. The aim of this study is to test if the soil’s effective hydraulic conductivity also adapts in such a way that it produces maximum power. However, the soil’s hydraulic conductivity adapts differently; for example by the creation of preferential flow paths. Here, this process is simulated in a lab experiment, which focuses on preferential flow paths created by piping. In the lab, we created a hydrological analogue to the atmospheric model dealing with heat transport between Equator and poles, with the aim to test if the effective hydraulic conductivity of the sand bed can be predicted with the maximum power principle. The experimental setup consists of two freely draining reservoir connected with each other by a confined aquifer. By adding water to only one reservoir, a potential difference will build up until a steady state is reached. The results will indicate whether the maximum power principle does apply for groundwater flow and how it should be applied. Because of the different way of adaptation of flow conductivity, the results differ from that of the atmosphere. [less ▲]

Distinguishing the analysis of spatial data from classical analysis is only meaningful if the spatial components bring information. Therefore, testing if the spatial autocorrelation is significant may confirm or deny the need to consider spatial analysis over the classical one. Spatial autocorrelation expresses the dependence between values at neighbouring locations. Several measures of spatial autocorrelation are defined in the literature. Moran’s index, Geary’s ratio and Getis-Ord statistic are the most used statistics. Tests based on these measures have been developed in the literature using asymptotic and permutation results. They are used in practice in many fields, for instance in geography, economics, biogeosciences, medicine, ... However, these tests should be cautiously applied because they are not robust. A single contaminated observation can significantly modify their results. The talk has two main objectives. Firstly, the already available tools for measuring spatial autocorrelation will be reviewed with an emphasis on the study and comparison of their robustness. Secondly, alternative methods will be proposed to robustly estimate the spatial autocorrelation. [less ▲]

With unprecedented speed and extent, the future climate change can be expected to severely impact terrestrial ecosystems due to more frequent extreme events, such as droughts or heat waves. What will be the impacts of these extreme events on ecosystem functioning and structure? How far will net primary production be reduced by such events? What will be the impact on plant mortality? Could such events trigger changes in the abundance of plant species, thus leading to biome shifts? In this contribution, we propose to use ISI-MIP2 model historical simulations from the biome sector to analyse the response of ecosystems to droughts or heat waves, trying to understand the differences between several vegetation models (e.g. CARAIB, HYBRID, LPJ). The analysis will focus on Europe. It will compare and assess the model responses for a series of well-marked drought or heat wave events in the simulated historical period, such as those that occurred in 1976, 2003 or 2010. This analysis will be performed in terms of several important environmental variables, like soil water and hydric stress, runoff, PFT abundance, net primary productivity and biomass, fire frequency, turnover of soil organic matter, etc. Whenever possible, the response of the model will be compared to available data for the most recent well-marked events. Examples of data to be used are eddy covariance, satellite data (including leaf area and fire occurrence) or tree rings. [less ▲]

Various (inter)national organizations and institutions expend a great deal of effort on fighting against the dramatic grow of the sedentariness of the modern society. In consumer magazines as well as in prestigious scientific journals, number of publications emphasize the interest that each of us can withdraw from a regular active lifestyle. So, nowadays, in the Western countries, everyone is supposed to know that physical activity is one of the ingredients of a healthy lifestyle. Nevertheless, it is clear that the population seems to paradoxically misunderstand the concept of physical activity. Moreover, in terms of sedentariness, the female audience is considered as particularly at risk and requires specific attention. According to the socioecological models, physical activity behaviors are influenced by a large array of variables belonging to the person itself as well as for its social, built, natural environments, and policies. In parallel, the transtheoretical model of health behavior change emphasizes that a person who changes his/her behavior goes through five stages (precontemplation, contemplation, preparation, action, and maintenance). Following that theory, the starting point of the change process consists of the awareness of the individual about the behavior. This stage refers to the individual factors linked to psychological, cognitive and emotional aspects (knowledge about PA, expected benefits, motivation, perceived pleasure …) that can be related to the people’s representations about PA. A representation can be defined as a mental phenomenon that corresponds to a more or less conscientious, organized and consistent set of cognitive and affective elements concerning one particular object. The goal of this paper is to underline the interest of the analysis of the representations about PA in a way to understand the reasons of reluctance, motivation and/or blockages demonstrated by individuals - and by women in particular - in their changing process. Study on such topic could become a key aspect in the search for useful tools in the habits transformation. In fact, despite representations’ central role, very few studies focusing on this variable have been published in the literature. This is especially surprising as it was demonstrated that representations about PA have a bigger influence on the lifestyle modification than concrete environmental variables do. When considering representations about PA, we consider five elements: definition, believes about the impacts, knowledge of the recommendations, self-evaluation, and identification of the change strategies). These questions will be the focus of the paper. Data will support and illustrate their legitimacy in the physical activity promotion. [less ▲]

The univariate coefficient of variation (CV) is a widely used measure to compare the relative dispersion of a variable in several populations. When the comparison is based on $p$ characteristics however, side-by-side comparison of marginal CV's may lead to contradictions. Several multivariate coefficients of variation (MCV) have been introduced and used in the literature but, so far, their properties have not been much studied. Based on one of them, i.e. the inverse of the Mahalanobis distance between the mean and the origin, this talk intends to demonstrate the usefulness of MCV's in several domains (finance and analytical chemistry) as well as provide a complete inference toolbox for practitioners. Some exact and approximate confidence intervals are constructed, whose performance is analyzed through simulations. Several bias-correction methods, either parametric or not, are suggested and compared. Finally, since MCV's are used for comparison purposes, some test statistics are proposed for the homogeneity of MCV's in $K$ populations. Throughout the talk, the robustness of the techniques will be discussed. As a by-product, a test statistic allowing to reliably compare $K$ univariate CV's even in presence of outliers will be outlined. [less ▲]

Ethane is the most abundant non-methane hydrocarbon in the Earth's atmosphere and an important precursor of tropospheric ozone. Its monitoring is therefore crucial for the characterization of air quality and of the transport of tropospheric pollution. Ethane is also an indirect greenhouse gas, influencing the atmospheric lifetime of methane. The main sources of ethane are located in the northern hemisphere, and the dominating emissions are associated to production and transport of natural gas. A preliminary trend analysis was conducted using measurements performed in the Swiss Alps. Over the last two decades, the trend of ethane showed a decline of around 1% per year, thanks to a reduction of fugitive emissions of fossil fuel sources. However, a recent upturn potentially attributed to the massive exploitation of shale gas and tight oil reservoirs in North America was found. The goal is to investigate the presence and form of changes in trend functions using nonparametric techniques. The possible location of such changes is investigated. In addition, nonparametric estimation techniques are used to allow for nonlinear trend functions. Given the nonstandard nature of the measurements we rely on dependent wild bootstrap techniques to conduct inference on possible breaks in linear trends and on nonparametric trend functions.

The Sahelian's environment suffered many perturbations increasing the food insecurity risks. Since three decades, the environment suffered a intense and significant land deterioration (Warren A. And al., 2001). A lot of regreening actions have been developped in the Sahelian countries but some actions are most sustainable and the costs are lower than the other. The International Fund for Agricultural Development (IFAD) has developped some actions to strengthen the natural ressources management. The most important actions have been introduced from the mi-term of 1,980 (Sendzimir J. And al., 2011). These actions concerned the main water and soil conservation technics: Zaï; „contour“ stone bund; half-moons; permeable rock dams (Wesel A., Rath T., 2002). The paper attempts to answer about the following question: „what are the indirect and direct socioeconomic impacts of the natural ressources management in the Maradi’s region ?“. Moreover, Maradi is the historical area of the IFAD actions and illustrates some major causes of land degradation. The main causes are the increase of demography and agricultural areas. In fact, the demography and agricultural area of Maradi are seriously worrying: 8 children per women and the agricultural area is less than 1 hectare per household (Andres L., Lebailly Ph., 2013). The paper relates and describes the main anti-erosion technics. It compared also the cost-benefit analysis about the soil and water conservation technics. Finally, the report try to establish a key who links the technics with the context (soil, people, environment, agriculture, livestock) (Moussa Dit Kalamou M., 2015; Jasmien C.J. and al., 2013).

Au départ des études sur la culture matérielle, le lien entre les choses et les sujets, établi par le biais du corps, sera exploré. La consommation, en tant que moyen d’incorporation des objets dans le soi et dans son propre univers de référence, constituera la porte d’entrée de l’analyse de ce lien. De l’élaboration des choix à la dé-marchandisation des produits, le processus qui engage simultanément choses et sujets jette les bases de la définition individuelle et des relations sociales. L’alimentation en est un exemple concret. Pratique qui stimule la réceptivité multidimensionnelle du corps, elle permet également de s’interroger sur le rôle de celui-ci non seulement dans les dynamiques de consommation mais aussi dans les démarches ethnographiques visant leur compréhension.

Much attention is paid to sea-level rise due to climate change. However, the problem of land subsidence because of human-induced changes of (fluid) groundwater conditions in the underground can be by far more significant locally (Showstack, 2014). The ‘sinking’ regions correspond most often to densely populated coastal areas located in regions where compressible and under-consolidated loose sediments are found. This is the case in late Quaternary coastal settings consisting of estuarine, deltaic and lagoonal sediments. Venice, Mexico, Bangkok, Shanghai, Changzhou, Jakarta, Manila, New Orleans, Houston, Tokyo, Ho Chi Minh City, Hanoi, … are only a few examples among the numerous ‘sinking cities’ (Gambolati & Teatini, 2015). Late Quaternary, and more particularly Holocene unconsolidated or semi-consolidated deposits form often a succession of layers that can be considered, from a hydrogeological point of view, as semi-confined or confined aquifer systems (Poland, 1984). In confined aquifers but also in unconfined aquifers, the lowering of the piezometric head due to pumping or drainage induces additional effective stresses directly in the concerned aquifer and then, with a delay depending on their characteristics, in the compressible confining layers or in the compressible lenses of silt, clay, and peat included in the aquifer. Coupling the transient groundwater flow equation with geomechanical aspects, allows understanding of the considered transient processes induced by the artificial lowering of the water pressure in the porous medium. For accurate calculations, used for understanding the observed subsidence and predicting the future subsidence, it is important to take into account the strongly non-linear effects such as the variation of the specific storage coefficient and of the permeability during the consolidation process (Dassargues, 1995, 1997, 1998). Typical and emblematic examples involving regional as well as very local land subsidence will be presented showing the general approach. Land subsidence is an important issue linked to global change and groundwater management challenges (Gorelick & Zheng, 2015). [less ▲]

Le recyclage n'est pas un luxe ou une mode mais une nécessité, qui provient d'une constatation fort simple: nous vivons dans un monde limité. Contrairement à ce que nous avons cru fort longtemps, notre activité humaine n'est pas infiniment développable, car limitée en termes d'énergie, de ressources naturelles, d'espace ou simplement de capacité d'adaptation de la nature. De cette constatation et de cette prise de conscience doit découler un comportement qui, essentiellement, est basé sur le respect que nous avons de nous-mêmes et donc de la nature (à ménager et non à aménager). Cette démarche nécessite une vision d'ensemble de la vie du matériau ou de l'objet (Analyse du Cycle de Vie), au cours de laquelle un bilan est établi à chaque étape de vie - extraction des matières premières, fabrication, transformation, recyclage, élimination. Par ailleurs, le monde de la construction constitue à la fois un gisement et un marché énormes. Les ressources secondaires provenant du recyclage et de la biomasse représentent autant de possibilités de développer des nouveaux matériaux mieux adaptés aux exigences physiques et mécaniques. La construction traditionnelle vit en effet de profonds changements liés au fait que la « résistance » n’est plus le seul critère de qualité : l’argile crue, la paille, le miscanthus, …… se retrouvent aujourd’hui à la base de développements expérimentaux et numériques qui contribuent à une meilleure isolation thermique en même temps qu’un confort hygro-thermique mieux adapté. L’habitat exploite les ressources secondaires et les matériaux bio-sourcés en vue d’une meilleure intégration de l’activité humaine dans son environnement naturel, contribuant par là-même à la protection et la préservation de notre patrimoine commun.

This research analyzes the gender dimensions of labor migration and agricultural production among farm households in Red River Delta region of Vietnam. Through surveying 215 households in Bac Ninh province, the paper explores impacts of female and male migration on agricultural production and its implications on rural development. The results show that in comparison to male migration household, the female one tends to focus on agricultural production by taking the opportunities to rent more land (26.3%) and effective use their own allocated land for agricultural production (97.4%). The overall impacts of migration on agricultural production are the aging of farm labor force (49.6 year old in average) and higher female participation in agricultural production. The findings suggest that female migrants have a greater contribution in agriculture production both in term of working time and agricultural capital investment while male migrants enhance household income by accumulating capital outside agriculture. Through the gender lens, this research emphasizes the duality in the nature of migrant lives and the implications of rural labor migration on the fixed categories. [less ▲]

Traumatic Lumbar hernia (TLH) is a very rare clinical entity with about 100 cases reported worldwide. It is a difficult challenge when encountered and there is no consensus on the best management: early or delayed, open or laparoscopic. We report the clinical case of a 28-year-old man who suffered from a TLH after a 6- meter-high fall. The diagnosis was based on CT imaging showing a defect in the postero-lateral abdominal wall by disinsertion of the lumbar origin of transverse, internal and external oblique muscles. A few months after the trauma, it became gradualy more painful, the hernia was clinically increased with a large swelling on the right flank majored by valsalva. CT imaging showed herniation of the right colic flexure through the defect. Eight months after the trauma, we performed an intra-abdominal laparoscopic approach. Herniated structures were reduced and we opened the peritoneum. The defect was repaired by placing a pre-peritoneal polypropylene mesh fixed by laparoscopic staples before closing the peritoneum. The patient had an uneventful recovery. Ten weeks after the surgery the result was clinically very good. The CT scanner showed a good recovery of parietal continuity. [less ▲]

The University of Liège has more than twenty years of experience in the use of ion beam analysis techniques for cultural heritage research. We will present here some of the recent developments. First, we have developed a high energy extracted beamline up to 20 MeV on our cyclotron with a good energy resolution of a few keV. These last years Ion Beam Analysis users show an interest in High Energy Alpha beam. These beams can be used for on-site analysis by means of radioactive sources e.g. for space application but they also offer a powerful combination of properties for the analysis of thick layers (about 10 to 20 µm). This kind of layers are often met in cultural heritage applications but can be also present on new materials. Contrary to this kind of materials where the principal information needed is the in-depth profiles as the sample are of known composition, for cultural heritage materials the combination of elemental analysis and their in-depth distribution is essential as the nature of the material is a-priori not known. We will also present the development around our first extracted beamline. We have indeed improved the automatic scanning system for macro-PIXE. Some examples will be shown. Finally we will show other non-invasive analysis developments related to cultural heritage. [less ▲]

Contrairement à la seconde reconstruction qui reste aujourd’hui largement inexplorée, la première reconstruction en Belgique a fait l’objet de nombreuses recherches et publications. Et pourtant, une figure essentielle n’a que très peu retenu l’attention des chercheurs : le chanoine Raymond A.G. Lemaire. Professeur d’archéologie et de restauration à l’université de Louvain, chantre du néogothique dans le sillage de Joris Helleputte, il participe activement aux débats de la reconstruction, non seulement à Louvain, où il est membre de la Commissie voor Stedenschoon, mais dans tout le pays, en tant que membre correspondant de la Commission royale des monuments et des sites et conseiller de l’archevêché de Malines. Auteur de nombreux articles, il synthétise les débats dans “La restauration des monuments anciens”, publiée à Anvers en 1938, tout en développant une approche personnelle se nourrissant de la théorie des valeurs d’Aloïs Riegl et s’approchant de la théorie du “cas par cas” développée à la même époque, en Italie, par Ambroggio Annoni. Bien que les rapports entre les deux hommes ne soient pas documentés dans les archives belges, les nombreux parallèles entre leurs approches, ainsi que le fait que le chanoine Lemaire enverra son neveu, Raymond M. Lemaire, se former chez Annoni en 1943, laissent entendre qu’ils devaient exister. A travers notre participation à la conférence, nous espérons découvrir des éléments susceptibles d’alimenter la poursuite des recherches en ce sens. [less ▲]

Introduction. Selon Miyake et al. (2000), le fonctionnement exécutif serait sous-tendu par trois fonctions distinctes - l’inhibition, la flexibilité et la mise à jour - alors que d’autres auteurs (Fisk & Sharp, 2004) suggèrent qu’elles seraient au nombre de quatre (coordination de tâche double). On sait aujourd’hui que l’avancée en âge s’accompagne d’un déclin exécutif. Toutefois, peu d’études ont étudié l’impact de variables non-exécutives (et plus particulièrement attentionnelles) sur la variabilité des performances exécutives dans le vieillissement. Méthode. 114 participants jeunes et 65 participants âgés ont réalisé un ensemble de tâches cognitives évaluant les quatre aspects du fonctionnement exécutif : l’inhibition (Stroop, Anti-saccade, Stop-Signal), la flexibilité (Plus et Moins, Chiffres-Lettres, Global-Local), la mise à jour (Mise à jour sonore, Mise à jour sémantique, Mise à jour de consonnes) et la coordination de tâche double (PASAT, Brown-Peterson, Attention divisée (TEA)). Par ailleurs, nous avons mesuré la vitesse de traitement de l’information (Comparaison de lettres, Stop-signal contrôle, Alerte tonique, Vitesse articulatoire), le fonctionnement attentionnel dans ses aspects d’alerte phasique, d’orientation visuelle externe (Balayage visuel, Motilité oculaire) et d’attention soutenue (Détection d’irrégularités visuelles, Détection de cibles), ainsi que le niveau d’empan. Nous avons tout d’abord comparé les performances des deux groupes sur chacune des tâches exécutives. Pour celles où nous avons observé une différence entre les groupes, nous avons tenté de déterminer si certaines variables non-exécutives pourraient expliquer une part de la variance des performances de nos participants âgés. Résultats. Les comparaisons entre groupes révèlent que les sujets jeunes ont toujours (sauf pour la tâche Stop-Signal) des performances exécutives supérieures à celles des âgés (p<0.01). Lorsque les différentes variables attentionnelles et non-attentionnelles sont introduites dans un modèle de régression multiple stepwise pas à pas, nous observons que les variables attentionnelles expliquent une part significative de la variance pour la tâche Chiffres-Lettres (alerte), la tâche de Mise à jour sémantique (orientation visuelle externe), la tâche de Mise à jour de consonnes (orientation visuelle externe) et la tâche d’attention divisée (alerte et orientation visuelle externe). Discussion. En accord avec de précédentes études, le fonctionnement exécutif décline avec l’âge. Nos résultats indiquent que le déclin de certaines fonctions (mais pas toutes) serait modulé par les capacités attentionnelles. Cette modulation attentionnelle ne serait toutefois pas un processus général, mais dépendrait des caractéristiques propres à chaque tâche. [less ▲]

Since the end of the 80’s, physical education (PE) is a right for any citizen. Nevertheless, this school subject experienced a crisis expressed by a certain marginalization, a reduction of the curriculum time allocation, some questioning about the subject status, repeated decreases of material, human and financial resources as well as presence of inadequacies in facility and equipment supply, or a low remuneration of teachers. However, since two decades, the growing recognition of the benefits that society could get out one physically active lifestyle for health leads to a shift in the PE priorities. All around the world, PE teachers have to adapt their programs and teaching strategies in order to prepare physically educated citizens. It seems now essential to propose contents that will be more transferable in the out of school life. PE teachers are now expected to be the corner stones of the promotion of a healthy lifestyle that their students should acquire for their whole life. This attractive vision is not well supported by the literature, mainly when considering the long term effects. Reasons of that lack of achievement have been underlined and solutions are now proposed and implemented. Teachers are recommended to be models, update their knowledge, do networking, become project managers, and behave like real professionals. Moreover, they should foster students’ play and pleasure, achievement and learning, movement, interactions, and autonomy. Physical literacy and accountability became two major guiding principles of PE teaching. PE teachers’ education should rely now on pedagogical cases, communities of practice and action researches. A growing number of examples of good practices is available. In parallel, researchers implement studies aiming to analyse the effects of these initiatives. Using technology like computers, video, tablets, Web-based applications … is considered as a promising approach. [less ▲]

Les tâches de reconnaissance à choix-forcé et oui/non ont largement été utilisées dans l’évaluation de la mémoire. Selon Norman et O’Reilly (2003), le format oui/non ferait davantage intervenir la recollection alors que le format à choix-forcé favoriserait la comparaison du sentiment de familiarité associé à chaque item et la sélection du plus familier. L’objectif de cette étude est d’explorer l’impact du format du test sur la recollection et la familiarité au travers du vieillissement normal et pathologique. Septante participants jeunes (18 - 30 ans), 65 participants jeunes-âgés (55 - 69 ans), 53 participants âgés-âgés (70-85 ans) et 13 patients présentant un trouble cognitif léger amnésique (55-82 ans) ont réalisé deux tâches de reconnaissance. Pour chaque tâche, lors de l’encodage, nous avons présenté, à deux reprises, 25 images à mémoriser. Dans la tâche de reconnaissance à choix forcé, les participants devaient reconnaitre parmi trois images très semblables celle qui a été vue précédemment. Dans la tâche de reconnaissance oui/non, les items étaient présentés successivement et les participants devaient reconnaitre ceux présentés à l’encodage. Pour chaque item reconnu, les participants devaient fournir un jugement Remember/Know/Guess. Les ANOVA Groupe x Format à mesures répétées sur la dernière variable (p<0,05) ont révélé que les jeunes avaient de meilleures performances en reconnaissance (score d’) que les jeunes-âgés, qui ont eux-mêmes de meilleures performances que les âgés-âgés et les patients. En outre, les jeunes utilisent plus souvent le sentiment de familiarité pour reconnaître les images étudiées que les participants âgés et les patients. De plus, les participants jeunes-âgés utilisent plus souvent la familiarité que les participants âgés-âgés, alors qu’il n’y a pas de différence entre ceux-ci et les patients. Cependant, les fausses alarmes associées à la familiarité augmentent progressivement dans le vieillissement et la pathologie. L’utilisation de la recollection est progressivement réduite avec l’âge et altérée dans la pathologie. Enfin, les jeunes tendent à utiliser plus souvent la recollection dans la tâche à choix-forcé (p=0,055), alors qu’il n’y a pas de différence pour les autres groupes. Tous ces résultats suggèrent que le vieillissement normal s’accompagne d’un déclin progressif de la recollection et de la familiarité. Dans le vieillissement pathologique, on observe des performances similaires au groupe le plus âgé en reconnaissance malgré un déficit de recollection. Les patients utilisent la familiarité autant que les deux groupes âgés bien que les taux de fausses alarmes soient plus importants, suggérant une utilisation privilégiée mais inadéquate de ce processus.

Thanks to their biocompatibility and degradability properties, polyphosphates are appealing polymers for biomedical applications. In contrast to aliphatic polyesters, such as poly(ε-caprolactone) and poly(lactide), the pentavalency of the phosphorus atom allows the easy modification of the polyphosphate properties by simply adjusting the nature, the length and the functionality of the polyphosphate pendant groups. Macromolecular engineering of polyphosphoesters was applied to design well-defined architectures and functionalities adapted to drug nanocarriers. In a first approach, amphiphilic block copolymers are synthesized by organo-catalyzed ring-opening polymerization process for the synthesis of a range of PEO-b-polyphosphate bearing various pendant groups. Post-polymerization thiol-ene click reactions preformed on PEO-b-polyphosphate copolymers was also investigated to improve the hydrophobicity of the polyphosphate. The self-assembly of these PEO-b-polyphosphate copolymers into micelles was investigated, particularly, the effect of the nature of the polyphosphate pendant groups (i) on the micelles characteristics, (ii) on the encapsulation of a poorly soluble drug and (iii) on the drug release profile. The toxicity of the different amphiphilic block copolymers was also evaluated by live/dead cell viability assays. In a second approach, double hydrophilic copolymers based on polyphosphoesters have been used as templating agent for the synthesis of calcium carbonate particles. Indeed, the use of such microparticles is becoming more and more attractive in many fields especially for biomedical applications for which fine tuning of size, morphology and crystalline form of CaCO3 particles is crucial. Although some structuring compounds, like hyaluronic acid, give satisfying results, the control of the particle structure still has to be improved. To this end, we evaluated the CaCO3 structuring capacity of the well-defined double hydrophilic block copolymers composed of poly(ethylene oxide) and of a polyphosphoester segment with affinity for calcium like poly(phosphotriester)s bearing pendant carboxylic acids or poly(phosphodiester)s with a negatively charged oxygen atom on each repeating monomer unit.

In this paper, we model the severity distribution of operational losses data, condi- tional on some covariates. Indeed, previous studies [Chernobai et al., 2011, Cope et al., 2012, Chavez-Demoulin et al., 2014a] suggest that this distribution might be in uenced by macroeconomic and rm-speci c factors. We introduce a conditional Generalized Pareto model, where the shape parameter is an unknown function of a linear combina- tion of the covariates. More precisely, we rely on a single-index assumption to perform a dimension reduction that enables to use univariate nonparametric techniques. Hence, we su er neither from too strong parametric assumption nor from the curse of dimen- sionality. Then, we develop an iterative approach to estimate this model, based on the maximisation of a semiparametric likelihood function. Finally, we apply this method- ology on a novel database provided by the bank UniCredit. We use rm-speci c factors to estimate the conditional shape parameter of the severity distribution. Our analysis suggests that the leverage ratio of the company, the proportion of the revenue coming from fees as well as the risk category have an important impact on the tail thickness of this distribution and thus on the probability of su ering from large operational losses.

Pour appuyer les efforts de conservation de la biodiversité, des processus de transfert de gestion (TG) des ressources naturelles aux communautés locales de base ont été promus à Madagascar depuis 1996 avec un important financement étranger. Ce p’rocessus était censé stimuler une forte responsabilisation des acteurs en plaçant la prise de décisions dans la sphère locale, ce qui améliorerait l’efficacité. Le transfert de fonds et de capacité ainsi que l’appui des partenaires sont également requis pour rendre la décentralisation effective. Pourtant, un désintérêt et une déresponsabilisation croissants quant à la gestion des ressources par les populations locales ont été souvent constatés et le taux de déforestation est resté élevé. C’est le cas de la zone forestière de Mariarano où nous avons eu l’occasion d’observer la mise en œuvre d’un TG. A travers les perceptions des acteurs clés dans le TG : la communauté locale et l’administration forestière, ce travail consiste à dévoiler les enjeux du processus participatif, les impacts de la dépendance à l’aide, les stratégies de contournement des règles par la population locale et l’évolution des rapports entre l’administration et ses partenaires dans le cadre de l’Etat local. A travers des actions déterminées par des prescriptions légales et des délais, les agents d’appuis activent le processus, négligent les clivages au sein de la population locale et cadrent les décisions résultants des négociations vers l’objectif de conservation. Cette procédure fait naître un sentiment d’imposition et aggrave l’illégitimité des normes promues. Par ailleurs, la population locale adopte un comportement opportuniste. Leur participation au processus fonctionne plus comme un mode de contrôle et d’accès aux ressources qu’un mode de préservation de celles-ci. Pour la réalisation des tâches attribuées à la population locale et des activités alternatives des usages, dont l’accès est désormais réglementé, l’appui des partenaires est nécessaire vu leurs faibles capacités financières et techniques. Toutefois, les appuis restent ponctuels et limités selon la priorité et la disponibilité budgétaire des bailleurs de fonds. La loi n’engage pas non plus les partenaires pour faire l’accompagnement sur le moyen terme, bien que ceci soit important pour provoquer des changements. Ceux qui n’ont pas ressenti les avantages concrets sont allés vers des pratiques illégales. Clandestinité et dissimulation sont les stratégies adoptées pour faire valoir leurs droits. Une amplification de la complicité au sein de la communauté gestionnaire est constatée pour contourner les règles. Quant au rapport de l’administration avec ses partenaires, il s’est détérioré. Dans un contexte marqué par la dépendance financière de l’Etat envers les bailleurs de fonds, l’administration est limitée dans ses fonctions et travaille comme consultant de ces derniers. Aux yeux des paysans, l’administration apparaît comme étant inapte à honorer ses engagements, ce qui nuit à sa crédibilité. Ainsi, elle rencontre des difficultés pour obtenir la confiance et la coopération de la population. Or celle-ci constitue le fondement de la gestion participative. La persistance des activités de déforestation résulte donc de l’illégitimité des normes résultantes du processus participatif, du recours des acteurs aux pratiques informelles et enfin de la paralysie de l’administration.

Mass and momentum exchanges in close massive binaries play an important role in the evolution of such systems and produce several observational signatures, such as asynchronous rotation and altered chemical compositions, that remain once the stars detach again. We have started to investigate these effects for a sample of detached massive O-star binaries that are thought to have previously experienced a Case A Roche Lobe Overflow. Using phase-resolved spectroscopy, we perform the disentangling of the spectra of the two stars. The reconstructed primary and secondary spectra are then analyzed to determine a range of stellar effective temperatures and gravity, and rotational velocities. Using model atmosphere codes we also constrain the chemical composition of the components. In this contribution, we present the results of our analyses of HD149404 (O7.5If + ON9.5I, P = 9.81 days) and the first results of our analyses of HD17505 ([O7.5V + O7.5V, P = 8.57 days] + O6.5III).

Les récits de fondation élaborés par bon nombre de communautés religieuses féminines et souvent prolongés par des chroniques, annales et abrégés de vertus jusqu’à leur suppression offrent de riches possibilités d’analyses des questions relatives aux vocations et à la représentation que s’en font ou que veulent en donner celles et ceux qui en sont les auteurs. Loin de ne recenser que les itinéraires les plus « linéaires », quantité de textes évoquent les destins contrariés et les changements de cap et proposent leur propre interprétation des motifs qui ont justifié les demandes – d’entrée ou de sortie – des unes et les réponses – acceptation ou refus – des autres. On se propose de prendre ici en compte des textes inédits produits par des religieuses contemplatives (annonciades, bernardines et bénédictines) dont les maisons se sont implantées ou réformées au XVIIe siècle en Franche-Comté, en Lorraine et aux Pays-Bas méridionaux – sur une « dorsale catholique » faisant face aux mondes protestants –, que l’on confrontera aux normes propres à leur institut et aux règlementations des pouvoirs civils et religieux des territoires concernés. On tentera d’analyser tout d’abord comment s’énonce la vocation de femmes qui souhaitent, dans ce contexte particulier, défendre leur choix de vie contemplative face aux exigences ou aux objections des autorités compétentes. On suivra l’évolution de leur argumentation depuis le temps où elles tentent de développer leur institut jusqu’au moment où elles doivent en défendre les fondements en réponse aux projets de sécularisation ou de suppression. On abordera ensuite la question des vocations individuelles en examinant comment les annalistes relatent et interprètent les motivations spirituelles mais aussi sociales et économiques des postulantes (et de leur entourage) et expliquent longuement les raisons des éventuels renvois ou sorties (aptitudes intellectuelles et physiques, traits de caractère, divergences de vue avec la communauté, pressions familiales...). On analysera les nombreuses protestations de fidélité aux règles des fondateurs concernant les conditions d’admission, mais aussi les justifications avancées par les intéressées quand il s’agit de les adapter ou d’y déroger. On examinera encore comment les autrices perçoivent la question des vocations forcées et critiquent la société qui en serait responsable. Enfin, on tentera de voir comment ces femmes réagissent face aux mesures prises par les autorités civiles pour surveiller et limiter leurs possibilités de recrutement. Dans un troisième temps, on examinera brièvement quelques cas de demandes de sortie temporaire ou définitive (au départ d’une enquête documentaire plus vaste) dont on tentera de percevoir l’écho – réprobateur ou compréhensif – dans les récits de celles qui restent.

La régularité en un point d'une fonction peut être caractérisée par son exposant de Hölder. Si la fonction est très irrégulière, celui-ci peut varier fortement d'un point à l'autre. Dans ce cas, il est naturel d'étudier la distribution des exposants de Hölder: cette information est donnée par le spectre de singularités de la fonction. En général, ce spectre est assez difficile à calculer et on utilise des méthodes pour l'estimer. Plusieurs méthodes basées sur la décomposition en ondelettes ont été proposées ; elles reposent sur une caractérisation de l'exposant de Hölder par les coefficients d'ondelettes. Dans cet exposé, nous introduisons une nouvelle technique reposant sur des estimations de grandes déviations basées sur les coefficients d'ondelettes et montrons son efficacité sur plusieurs exemples [less ▲]

In the last decade, the progress in computing power – both CPU and GPU – has allowed the development of photogrammetry softwares. These softwares can turned a set of photos of an object – such as a building – into a 3D model. They compete with laser scanners which are usually used for scanning objects like buildings and landmarks. In this paper, we compare outcomes of the software Smart3DCapture[4] with laser scanner point clouds of various scenes in order to evaluate the accuracy of photogrammetry reconstruction [less ▲]

The aurorae on Jupiter and Saturn are the most powerful proper ultraviolet emissions in our solar system, after the Sun’s. They can only be observed outside the absorbing atmosphere of the Earth with space telescopes such as the Hubble Space Telescope or the Hisaki Telescope, or from Spacecraft orbiting these planets, like Cassini for Saturn and Juno for Jupiter. We will review the types of observation that can be obtained with these different instruments and how this information can be used to interpret the auroral emissions. [less ▲]

Hydrogeophysics has become a major field of research in the past two decades and time-lapse electrical resistivity tomography (ERT) is one of the most popular techniques to monitor passive and active processes in subsurface reservoirs. Time-lapse inversion schemes have been developed to refine inversion results; but, in contrast with static inversion, they mostly still rely on the spatial regularization procedure based on the standard smoothness constraint. In this contribution, we propose to apply a variogram-based regularization operator in the time-lapse ERT inverse problem, using the model difference covariance matrix to replace the standard smoothing operator. The variogram of resistivity variations can be computed through independent borehole data, such as electromagnetic logs or hydrogeological monitoring, which is often available during monitoring experiments. We first illustrate the method for surface ERT with a synthetic case and compare the results with the standard smoothness constraint solution. This example shows that the variogram-based constraint images better the assumed anomaly both in terms of shape and amplitude. The improvement is largely higher than the one obtained with more classical anisotropic smoothness constraint. This synthetic example also shows that an error made in the range of the variogram has a limited impact on the resulting image, which still remains better than the smoothness constraint result. Anomalies located in various part of the tomograms were tested. Although more crucial in low-sensitivity zones, improvements are observed everywhere in the tomograms. The method is then applied to cross-borehole ERT field data from a heat tracing experiment, where the comparison with direct temperature measurements shows a strong improvement of the breakthrough curves retrieved from ERT. Using the variogram-based regularization, it is possible to reduce the smoothing of resistivity variations in low sensitivity zones and therefore to avoid overestimation of temperatures. The proposed method could be extended to the time dimension which would allow the use of variogram-based constraints in 4D inversion schemes. [less ▲]

L’activisme associatif dans le domaine de la déficience intellectuelle a connu des évolutions significatives depuis quelques décennies. Suivant les principes fondateurs de la Convention des Nations Unies relative aux droits des personnes handicapées (2006), les associations de personnes concernées revendiquent leur légitimité à s’impliquer activement dans la gouvernance des questions qui les concernent. Cette communication porte sur les manières dont de jeunes adultes dits porteurs de déficience intellectuelle sont sujets à des processus de subjectivation et de désubjectivation au travers de discours et pratiques associatives qui revendiquent leur pleine inclusion et participation à la société. Croisant nos recherches respectives en sciences sociales et en philosophie politique, nous mobilisons une approche du sujet observé en situation (Agier, 2012) en vue d'envisager des « scènes de subjectivation » formelles et informelles dans le cadre d'une association belge francophone, en ce qu’elles nous semblent effectivement donner à voir de telles dynamiques de (dé)subjectivation par lesquelles se (re)construisent constamment les sujets porteurs de déficience intellectuelle et leur capacité d’agir.

La détermination des propriétés hydrauliques du sol est une préoccupation majeure dans différents domaines d’études. Bien que les sols caillouteux soient répandus dans le monde entier, la plupart des études ne caractérisent que la fraction fine des sols, si bien que la littérature décrivant l’impact des cailloux sur les propriétés hydrauliques du sol est encore rare. Certains modèles ayant pour but de caractériser ces propriétés hydrauliques reposent sur la même hypothèse simplificatrice, qui stipule que le seul effet des cailloux est de diminuer le volume disponible pour l’écoulement de l’eau. L’objectif de cette étude est de vérifier cette hypothèse et, le cas échéant, d’identifier les facteurs déterminant ou non son respect. L’effet des cailloux sur la conductivité hydraulique à saturation effective du sol a été testé au moyen d’expériences de laboratoire et d’expériences numériques, impliquant différentes quantités et types de fragments grossiers. Nos résultats montrent que plusieurs facteurs supplémentaires, non considérés par ces modèles, peuvent affecter significativement la conductivité hydraulique à saturation. D’une part, la forme et la taille des inclusions altèrent de manière substantielle la conductivité hydraulique. D’autre part, la présence de cailloux peut contrer -voire dominer- les effets liés à la réduction du volume disponible pour l’écoulement en conditions saturantes. Nous attribuons cela à la création de macropores à l’interface entre la terre fine et les cailloux. [less ▲]

The direct measurement of loads with force balance can become challenging when the forces are small or when the body is moving. An alternative is the use of Particle Image Velocimetry (PIV) velocity fields to indirectly obtain the aerodynamic coefficients. This can be done by the use of control volume approaches which lead to the integration of velocities, and other fields deriving from them, on a contour surrounding the studied body and its supporting surface. This work exposes and discusses results obtained with two different methods: the direct use of the integral formulation of the Navier-Stokes equations and the so-called Noca's method. The latter is a reformulation of the integral Navier-Stokes equations in order to get rid of the pressure. Results obtained using the two methods are compared and the influence of different parameters is discussed. The methods are applied to PIV data obtained from water channel testing for the flow around a 16:1 plate. Two cases are considered: a static plate at high angle of attack and a large amplitude imposed pitching motion. Two-dimensional PIV velocity fields are used to compute the aerodynamic forces. Direct measurements of dynamic loads are also carried out in order to assess the quality of the indirectly calculated coefficients. [less ▲]
