Le bilan de masse de surface (BMS) Antarctique est encore mal connu, bien qu’on sache qu’il contribue de façon significative à l’évolution actuelle du niveau des mers et que sa contribution soit supposée s’intensifier au cours des prochains siècles. Outre son effet direct sur le niveau des mers, le BMS est également un champs de forçage primordial pour les modèles de calotte. Enfin, alors qu’il existe des mesures directes de l’écoulement de la glace vers l’océan et des variations de masse totales (surface+écoulement) de la calotte, il n’existe pas de mesure directe du bilan de masse de surface à l’échelle du continent. La climatologie actuelle du BMS Antarctique est donc estimée principalement à partir de résultats de modélisation. Par ailleurs, le BMS est le résultat de processus complexes. Afin de le modéliser correctement, il est nécessaire de bien représenter la circulation atmosphérique et les processus physiques spécifiques aux régions polaires. Or les modèles de circulation générale présentent une résolution trop grossière et une physique peu adaptée pour modéliser correctement ces processus. Nous présentons ici des résultats de simulations réalisées le modèle atmosphérique régional MAR, qui fait référence pour la modélisation de l’atmosphère et des processus de surface en région polaire, à une résolution de 50 km pour la fin du 20ème et du 21ème siècle. Nous connaissons la qualité du modèle MAR, cependant, comme tout modèle atmosphérique régional, ses performances sont fortement liées à la qualité des forçages aux limites provenant des Modèles de Circulation Générale (MCG). Nous avons donc sélectionné le MCG le plus apte à simuler le climat présent parmi la nouvelle génération des MCGs provenant de la base de données CMIP5 (http://cmip- pcmdi.llnl.gov/cmip5/), qui seront utilisés dans le prochain rapport du GIEC. Cela est une étape cruciale car les MCGs ne représentant pas correctement le climat présent ne pourront pas donner de résultats probants pour les simulations futures. Nous nous penchons enfin sur l’épineux problème de l’évaluation du BMS modélisé à partir de données de terrain. En effet, un effort important a été réalisé pour répertorier les données de BMS de qualité en Antarctique, cependant nous montrons que ces données ne permettent pas d’évaluer les performances des modèles de façon suffisamment contraignante. L’utilisation d’autres types de données, satellites ou aéroportées par exemple, semble nécessaire, ce qui constitue un volet important de mes recherches en cours. [less ▲]

Este documento propone que las relaciones entre la Unión Europea (UE) y América latina (AL) han dado lugar al posicionamiento de una institución interregional originada en un intercambio discursivo. Esta se ha venido concretizando hasta construir una estrategia interregional europea de apoyo a la integración regional de América latina - SIEPIR-AL (por sus iniciales en francés). Es así como las regiones concernidas se han convertido en agentes de un subsistema encastrado dentro de un sistema multilateral neo-westfaliano en modo 2.0. Y como es el caso de todos los sistemas, éste se autorregula mediante una evaluación que puede compararse a la cibernética. La Facilidad de Inversión para América latina – LAIF, cuyo objetivo es el de facilitar el acceso a fondos para inversión en infraestructura para áreas relativas al medioambiente y al cambio climático, es uno de sus programas y surge como resultado de ese proceso cibernético. Su aplicación tiene por vocación el convertirse en una oportunidad para la profundización de la integración en AL especialmente en las zonas de frontera. [less ▲]

L’intervento sarà centrato sul materiale etnografico raccolto nel corso di una ricerca dottorale attorno alle pratiche culinarie di donne marocchine residenti nella città di Sesto San Giovanni (in provincia di Milano). In particolare, verranno messi in evidenza quegli aspetti della cultura materiale studiata che richiamano l’appartenenza delle donne considerate alla religione islamica. La ricerca ha infatti evidenziato come l’alimentazione (quotidiana o relativa a particolari eventi) e la stessa preparazione dei pasti siano influenzate non solo dalle prescrizioni che riguardano la distinzione tra il cibo lecito e quello illecito, ma anche da indicazioni relative a quali alimenti sia più opportuno consumare e in quali situazioni. Religione e tradizioni locali si intrecciano dando forma ad un sapere e un saper fare specifici, a loro volta negoziati dalle donne in questione al fine di far fronte alle costrizioni che il nuovo contesto in cui esse vivono impone. Tali aspetti costituiscono parte della materialità sulla e con la quale le donne considerate definiscono la propria soggettività, nel contesto domestico così come in quello pubblico. Verranno infatti illustrate anche le modalità in cui, seppur in spazi sovradeterminati, una partecipazione attiva delle donne alla vita sociale locale sia resa possibile grazie alla preparazione e presentazione di cibo, dando loro la possibilità di affermare anche pubblicamente la propria appartenenza religiosa ed eventuali rivendicazioni.

Une nouvelle série d'algèbres réelles généralisant l'algèbre des octonions, tout comme les algèbres de Clifford prolongent l'algèbre des quaternions, a été introduite par Morier-Genoud et Ovsienko en 2011. Ces algèbres, qui ne sont ni commutative, ni associative, peuvent être vues comme des algèbres twistées sur le groupe (ℤ2)n avec une fonction de twist cubique. La classification de ces algèbres est similaire à celle déjà bien connue sur les algèbres de Clifford. En effet, il existe beaucoup de symétries concernant les algèbres de Clifford et on peut les retrouver en partie pour les algèbres généralisant les octonions. Cette classification sera exposée lors du séminaire avec les idées de certaines preuves. [less ▲]

In this article, I start by looking at the historical origin of external voting in an attempt to define the practice as a set of administrative procedures. However, looking at its speedy global development, I argue that external voting is taking a different meaning for both sending and receiving societies in the era of globalization. Drawing on different examples from Europe, Latin America and Africa, and comparing the early development of external voting legislations with contemporary processes that lead to the enfranchisement of citizens abroad, I argue that the enfranchisement of citizens abroad is now part of a larger state strategy of developing external citizenship in order to capture what some scholars call the “diaspora resource”. For receiving states, I show through two case studies that the development of foreign electoral campaigns on their territory still triggers classic Westphalian fears of dual loyalties of immigrants. Nonetheless, I show that under specific circumstances, external voting can also be perceived by receiving states an opportunity to capture the votes of citizens enfranchised in both the sending and receiving societies.

Nowadays, conventional stamping is a well developed process. It is used for large production manufacturing which amortizes the cost of the tools. However, the possibility to use stamping processes for small volume production or prototypes can be still very expensive. As a result, the Single Point Incremental Forming (SPIF) emerges as a new possibility to solve the cost problem in small volume production. It is performed in a rapid and economic way without the need of expensive tooling. Its dieless nature makes the process appropriate for rapid prototypes and highly personalized pieces. Despite the progresses achieved during the last years, simulating SPIF through the Finite Element Method (FEM) continues nevertheless to be a demanding task. The constantly changing contact conditions between the tool and the sheet surface, as well as the nonlinear material model combined with non-monotonic strain paths during the forming process. In consequence, simulation time increases, even using shell hypothesis and simple geometries. Furthermore, the simulation with 3D “brick” elements in general increases the CPU time even more. To overcome this difficulty, an adaptive remeshing technique that was previously developed for the LAGAMINE code for shell elements [1] and afterwards extended to RESS (Reduced Enhanced Solid-Shell) finite element [2]. This allows that a portion of the sheet mesh is dynamically refined only in the tool vicinity, following its motion. Accordingly, this avoids the requirement of initially refined mesh and, consequently, the global CPU time is reduced. The current study will be focused in a benchmark simulation example applied to a component made by SPIF process using adaptive remeshing combined with RESS finite element. [less ▲]

Whether the University provides technological tools and services to students or/and whether they choose themselves which one to use, it is now really difficult for a student to pursue higher education without using a digital environment. This situation leads to the emergence of two concepts: Personal Learning Environment and Customized Institutional Learning Environment. The authors define them and consider their competition or complementarity. Afterwards, through question-naires addressed to university students, they observe in which way they are famil-iar with technologies and have a «digital native» profile. Then, they interview a sample of students presenting different technological profiles to bring out their representations and uses regarding customization of their digital learning envi-ronment.

With the aim of simulating the cooling behavior after a re-austenitizing stage of bimetallic rolling mills, both materials corresponding to spheroidal graphite iron (core material) and high chrome steel (shell material) must be characterized through thermo physical and mechanical tests as well as microscopic observations. Dilatometer tests were carried out for both materials in order to determinate thermo physical properties such as thermal expansion coefficient and density. Compression tests were also performed in order to estimate the effect of mechanical stress on martensite phase transformation, especially the nature and the type of martensite and start of transformation temperature. However there are some parameters that are still unknown and that are highly difficult to determinate. Inverse simulations are performed through Lagamine code with the aim of finding an estimated value for these parameters or improved parameters, more accurate than the ones already estimated.

Dans le cadre de la gestion des déchets ménagers dont la responsabilité incombe aux autorités régionales, la Région wallonne a délégué ( Arrêté du GW du 30 avril 1998) à des intercommunales le développement pour leurs communes affiliées (elles le sont toutes) d'une série de services en matière de gestion ou de prévention des déchets. Les intercommunales représentent des structures autonomes sous le contrôle relativement distant des responsables locaux des communes qui nomment leurs représentants au conseil d'administration. Ce niveau intermédiaire d'intercommunalité - qui est présent aussi dans d'autres secteurs tels que le redéploiement économique ou la production d'énergie verte - crée un espace spécifique en terme de territorialité, qui ne suit pas les lignes des territoires institutionnalisés (Région - Commune) mais organise des modalités de coopération à la fois proche et distante, à partir des flux financiers, d'information et de déchets. L'équipe du Spiral propose de présenter le rôle spécifique joué par les intercommunales de déchets, en prenant appui à la fois sur l'analyse du cadre institutionnel, les informations disponibles auprès de la Direction du Service Public de Wallonie en charge des déchets (y compris les récents rapports d'évaluation) ainsi sur une analyse concrète des pratiques développées par l'Intercommunale Intradel (Province de Liège) en relation avec quelques communes pilotes en matière de prévention des déchets (méthodes : entretiens et organisation d'un groupe de discussion entre communes).

The first part of the paper presents the technical constraints inherent to each machine through a state of the art of the three technologies. The second part of the paper deals with the modeling of such expanders. Finally, in the last part of the paper, performances of the various Rankine systems are compared and a decision array is built to select the most appropriate couple of fluid and expander. [less ▲]

In the present article, a model of scroll expander will be introduced. This model is able to evaluate the performance of a given machine with influence of the geometry. Several losses are also included by the model such as internal leakages, heat transfers or mechanical losses. The forces generated by the gas pressure on the involutes can also be calculated. That expander model is used in order to demonstrate its potential and provide some guidelines to the design of a new expander suitable for the application. [less ▲]

Poly-cultures are cropping systems using multiple crops in the same space and time, avoiding large stands of sole crops, hence contributing to reconciliation ecology. These land uses have several advantages over monocultures, e.g. increased biodiversity and diversification of agricultural production. Coupled with soil conservation measures, they also contribute to erosion control and resource protection in fragile areas. The viability of such systems often depends on their efficiency under limited resource conditions, which in turn makes them acceptable among the farming community. Most farmers, however, are reluctant to adopt such systems because they may compete for water and nutrients. This study was conducted during 2011 on the Queen Sirikit research farm, Ban Bo Wi village, Ratchaburi province, in North-West Thailand to investigate the competition in maize based soil conservation systems. The soil at the field site ranged from an endoleptic Alisol to ahyper skelletic Leptosol. The treatments were maize under farmer's practice (control) and maize-chili intercropping combined with alley cropping of Leucaena under minimum tillage and Jack bean relay cropping with and without fertiliser application. Plot size was 4 m by 13 m and slope of 18-20%. We used both carbon isotopic discrimination and electrical resistivity tomography (ERT) imaging, a novel non-invasive method, to understand and distinguish the competition for water and nutrients in tropical field conditions. A negative relationship was observed between 13C isotopic discrimination and total nitrogen in grain with R2 ranging from 0.63 (p ≤ 0.01) to 0.70 (p ≤ 0.001) while a positive correlation was found between total nitrogen in grains and total dry matter production with R2 ranging from 0.51 (p ≤ 0.04) to 0.84 (p ≤ 0.001). Nutrient competition induced an increase in δ13C values in maize rows close to Leucaena hedgerows and decreased their total dry matter production. ERT imaging showed different water depletion patterns during the growing season, directly linked with the growth and development of maize such as leaf area index, plant height and canopy cover. This helped explaining the impact of hedgerows on crop growth and yields in maize rows adjacent to the hedges, leading to various spatial patterns along the slope. [less ▲]

An approach is investigated for the modelling of the hydro-mechanical coupled behaviour of Callovo-Oxfordian claystone, a potential host rock for radioactive waste repositories in France. This approach is a double-scale finite element method, distinguishing a micro and a macro scale. At the micro level a representative elementary volume (REV) is used to model the material behaviour. The global response of this REV serves as an implicit constitutive law for the macro scale. On the macro scale, a poro-mechanical continuum is defined with fully coupled hydro-mechanical behaviour, the micro scale contains a model that takes into account the material micro structure to provide the material response to deformation and the associated stiffness matrices. Computational homogenization is used to retrieve the macro tangent stiffness from the micro level. This double scale approach is applied in the simulation of biaxial deformation tests, demonstrating the possibility of using the double scale modelling approach with the presented model at the micro level. The response at the macro level is compared with the micro-mechanical behaviour. [less ▲]

A detailed study on the building stock of Liege urban area (Belgium) has been conducted during 2011-2012. The study is focused on historic buildings, which were constructed before 1945 and represents a very significant share (68.33%) of Liege building stock. In the Walloon region, the average heating energy consumption per year of the building stock is 408 kWh/m2 and the average heating energy consumption per year stands at 340 kWh/m2 for Liege. Hence, it is important to study existing buildings to improve the energy efficiency as well as thermal comfort standards. It is also important to understand the behaviour of these buildings and the preferred indoor thermal environment of the occupants. Keeping this in mind, the indoor thermal environment has been monitored for ten residential buildings followed by detailed interaction with the occupants to record their preference and expectations about indoor thermal comfort. It was found from the analysis that the fluctuations in the temperature of living room and bedroom with respect to outdoor conditions are a function of occupant’s age, type of heating system and fuel used. It is also found that the average energy expenditure was very high in these buildings. The study further identifies specific areas that need to be taken into consideration in order to improve the thermal comfort and energy efficiency. It put forth the argument that to improve the energy efficiency of occupied houses, occupant’s preference and expectations on thermal comfort needs to be considered for designing sustainable solutions towards improving energy efficiency.

Si, depuis la plus haute antiquité, l'Égypte était renommée pour l'ancienneté et l'excellence de sa médecine, que se passa-t-il lorsque l'art médical grec hérité d'Hippocrate et de ses disciples y fut importé à la suite de la conquête d'Alexandre le Grand, en 332 avant notre ère ? À côté des sources littéraires qui font de l'"école médicale d'Alexandrie" un modèle qui restera pour longtemps inégalé, les papyrus médicaux grecs, retrouvés en nombre sans cesse croissant dans le Pays du Nil, permettent, avec d'autres sources archéologiques, d'apporter une réponse à la fois nuancée et surprenante sur l'étude et la pratique de la médecine dans l'arrière-pays égyptien.

Chacun le sait, le « passage au numérique » continue de bouleverser le cinéma : production, conception, écriture, distribution, réception, tous les aspects du champ cinématographique sont pris dans un processus de transformation. Interroger les contours technologiques du cinéma contemporain, c’est aussi questionner les formes cinématographiques de demain. Aussi, cette modeste conférence, après avoir tenté de délimiter la notion en vogue de « post-cinéma », pointera quelques-unes des problématiques les plus actuelles de l’évolution du langage cinématographique, dont la multiplication des plates-formes de visionnement, le filmage en 3-D, la motion capture ou l’hybridation prise de vues réelles et animation, pour offrir un rapide aperçu des nouveaux horizons du cinéma.

One of the defining features of Chinese new documentaries is the relationship which the filmmakers build with the subjects they are filming thanks to their bottom-up perspectives. In this paper, I will discuss Lü Xinyu’s argument that new documentary filmmakers have allowed “the power of reality to inter into their films” and that this reality “thereby exceeds their subjective will as filmmakers” (Lü 2010: 28). More specifically, by looking at how rural migrant workers are represented in these films, I will argue that new documentaries provide a very valuable vantage point in order to engage with the rich and at once highly contradictory dimension of rural migrant workers’ identity and agency made of aspirations, hopes, but also frustration, and hardship.

Recently, many munipalities have been concerned by muddy floods in Belgium after rain events. Unfortunately they lead to many consequences related to financial and emotional aspects. For many years the government have been trying to find solutions by helping municipalities by providing them with technical support through projects like ERRUISSOL and GISER. To implement solutions, it is necessary to be able to predict runoff flow path on agricultural watersheds. This is done by applying water flow direction algorithms on digital elevation model (DEM) built from elevation data. However, digital elevation models are not free of errors, and therefore they can impact the extracted flow path position. Our aim is to present the Monte Carlo simulation that is used to model the uncertainty of runoff flow path extracted from high resolution DEM built from terrestrial laser scanner. [less ▲]

We compare Morningstar ratings and ratings obtained using the same methodology of rating attribution with a set of commonly used performance measures. We study three types of investment horizons : 3-year, 5-year and 10-year ratings. Our analysis focuses on Open-End US Mutual Funds available in Morningstar Direct Database from which we create three sets of 16,617, 13,505 and 7,992 funds corresponding respectively to the three investment horizons analyzed. Our results show that Morningstar ratings are very close ( correlation around 80%) to ratings obtained with Sharpe's alpha, Jensen's alpha, Four-factor alpha and Excess returns. [less ▲]

La Corée du sud a connu au cours des dernières décennies un développement économique spectaculaire qui a longtemps servi de principale réponse à la résolution des questions sociales. Le dilemme croissance économique vs politiques sociales a pris une tournure nouvelle dans le courant des années 1990 avec l’entrée du pays dans l’OCDE d’une part, à cause de la crise de la fin des années 1990 d’autre part. Sous l’influence à la fois d’une société civile dynamique relayée par un pouvoir politique progressiste et d’une administration très influencée par le credo néolibéral de contrôle des dépenses publiques, la Corée du sud s’est engagée dans un développement mesuré mais incontestable –et inévitable- de son système de protection sociale. La logique dominante de workfare a débouché sur l’émergence d’un nouveau welfare-mix au sein duquel l’entreprise sociale est devenue un acteur important pour apporter une réponse à la question du chômage -et plus largement celle de l’exclusion ou du retrait du marché du travail- et à l’émergence de nouveaux besoins sociaux et environnementaux auxquels ni dispositifs publics, ni la sphère familiale ne sont pas en mesure d’apporter une réponse insuffisante. Dans une première partie, ce texte revient sur les principales transformations et caractéristiques du système sud-coréen de protection sociale. La deuxième partie analyse le développement récent de l’entreprise sociale et la troisième partie présente plus spécialement une des formes d’entreprise sociale qui apparait exemplaire : la coopérative médicale.

The fate of African tropical forests is a major concern for conservation, while their biodiversity is still poorly known. The purpose of this poster is to provide an update of knowledge of the genus Afzelia, a complex of sister tree species exploited for their wood in central Africa. The distribution of Afzelia in Africa suggests various adaptations to ecological factors. In fact, most of Afzelia species occur in parapatry and are so similar that they are often not distinguished by logging companies and forests managers. We show that the genus remains understudied in Africa although some of its species are considered as endangered or vulnerable. Therefore, a revision of its taxonomy along with thorough investigations of ecological and genetic aspects of Afzelia populations, using molecular markers currently in development (nSSR, cpDNA and nDNA), should be relevant and of great interest for conservation and sustainable management purposes. We will describe the different and complementary morpho-genetic approaches that will be used to investigate the biogeographical history of Afzeliapopulation in concert with species boundary questions.

Senegalese consumers seem to prefer local fresh milk-based dairy products rather than the ones produced with imported powder. However, market prices of both products do not appear to be different. This paper addresses this puzzle. First, I confirm the preference for local products. Using choice-based-conjoint data, I evaluate that Senegalese consumers are willing to pay a positive and significant premium for these products. Then, I identify the determinants of prices, based on a unique dataset of milk products characteristics. Evidence suggests that consumers' misinformation regarding the product composition prevents them from allocating a higher price to local milk-based products. [less ▲]

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

The STIS and ACS instruments on board the Hubble Space Telescope revolutionized our understanding of the aurorae at Jupiter. The high sensibility and high spatial resolution of these UV cameras allowed us to realize that these auroral emissions are made of a multitude of sub-components, such as the satellite footprints or the Polar Auroral Filaments. Moreover, these sub-components originate from very different regions in the magnetosphere and arise from totally different processes. Here I will review these newly described sub-components with a focus on what we understand, and, more interestingly, on what we still don't understand about them. [less ▲]
