La Moselle a connu, à bien des égards, une incontestable spécificité. De multiples déterminants ont pu laisser des marques ayant une influence sur les comportements politiques : circonstances historiques telles que les deux guerres mondiales et l'Annexion, variations géopolitiques, comme les différences linguistiques, distinctions entre régions rurales et industrielles, causes sociologiques comme la religion ou le pays d'origine des populations immigrés. Une approche du système partisan départemental, de son organisation et de ses structures, ainsi que des scrutins nationaux, entre la fin de la Seconde guerre mondiale et la "vague rose" de 1981 a permis de vérifier comment se traduit cette spécificité et quelle est son évolution : l'influence de la religion catholique est visible d'abord par une forte implantation de la démocratie chrétienne, puis par l'émergence de courants chrétiens de gauche ; l'importance du sentiment d'appartenance nationale entraîne une adhésion massive au gaullisme ; le P.C.F. se trouve en situation de quasi-monopole au sein de la gauche alors que, parallèlement, dans certains secteurs géographiques, le vote ouvrier est relativement orienté à droite. Sont aussi analysées les fluctuations des partis traditionnels : importance, puis déclin du parti gaulliste ; résurgence corrélative du centrisme et de la droite classique ; montée en puissance du parti gaulliste ; maintien, puis régression brutale du parti communiste, dans un contexte de crise des grandes industries du département. La spécificité politique de la Moselle s'amenuise, depuis le début des années soixante-dix, à mesure que décroit l'influence religieuse et que s'estompe le souvenir des guerres et de l'Annexion, et le département s'aligne sur la vie politique nationale, bien que l'exploitation des résultats électoraux permette malgré tout de mettre en évidence certains traits spécifiques persistants / In many respect, the Moselle department has know an undeniable specificity. Indeed many determiants have left marks that have had an influence on political behaviour : historical circumstances such as the two world wars and annexion ; geographical variations, linguistic differences, distinction between rural and industrial regions, sociological causes such as religion or the native countries of the immigrant population. The study of different political parties, their organization and structures and the national polls between the end of the second world war and the "pink wave" of 1981, has permitted to verify how this specificity traduced itself and now it evolved : the influence of the catholic religion is perceptible first in the strong implantation of the "Christian democracy", then by the emerging of a left wing Christien current ; the importance of the national feeling entails a massive adhesion to "Gaullism" ; the communist party is almost alone among the left wing political parties but at the same time, in some geographical sectors, the workers vote is relatively right wing oriented. Besides, the fluctuation of traditional parties are also studied : the importance and the decline of the Gaullist party ; correlative resurging of "centrism" and the traditional right wing politics ; rise of the socialist party ; maintenance and then brutal downfall of the communist party in a context of crisis for the big industries of the department. Since the beginning of the seventies, the political specificity of the Moselle department decreases in proportion as decreases the religious influence and as the remembrance of the war and annexation becomes smaller. The department now tends to fall into line with the national political life, even though the polls results stills point out to some persisting specifical traits

Title: Level of Detail AI: a prototype of a large virtual world Author: David Skupien Department: Department of Software and Computer Science Education Supervisor: Mgr. Cyril Brom, Ph.D. Abstract: The Level Of Detail technique (LOD) is an established means of optimization in computer graphics. It uses the limitations of human perception to spare system resources. Progressively, this approach has found its use in artificial intelligence. This adaptation, commonly known as LOD AI, is used to optimize autonomous agent control in large virval worlds. This thesis consists of two parts. The first part deals with standing LOD AI uses, mostly focusing on the IVE project. The second part directly uses the IVE project to implement a LOD AI game using the LOD based reactive planning algorithm called S-GHRP over the ISMA representation. The above game is then tested on respondents to verify the practical usability of S-GHRP/ISMA. In its conclusion, this thesis briefly ponders the possibilities of further development of techniques used in the IVE project, based on previous findings. Keywords: artificial intelligence, LOD AI, virtual agent, large virtual world, IVE

Esta dissertação investiga a influência de diversos fatores intervenientes nas emissões veiculares em corredores de ônibus de alta capacidade, conhecidos como BRT Bus Rapid Transit. Esses sistemas têm sido adotados em cidades de todo o mundo devido a possibilidade de atender demandas elevadas a custos relativamente baixos quando comparados com alternativas sobre trilhos, com nível de serviço adequado e possibilitando a redução de emissões. Três categorias de variáveis foram consideradas: (i) variáveis que são função do projeto do corredor de ônibus (infraestrutura, especificações tecnológicas e operacionais); (ii) variáveis que são afetadas pela implantação do corredor (impactos na velocidade média dos outros veículos, utilização de rotas alternativas e transferência modal); (iii) variáveis que dependem de políticas públicas (como mudanças do tipo de combustível ou programas de inspeção veicular). As emissões foram estimadas através de dois procedimentos. Preferencialmente utilizou-se o modelo IVE International Vehicle Emissions, que se baseia no ciclo de condução dos veículos (perfil de variação da velocidade segundo a segundo). Em alguns casos, as estimativas utilizaram resultados de medidas de emissões realizadas pelo IPT Instituto de Pesquisas Tecnológicas, para diferentes tecnologias de ônibus e ciclos de operação padronizados. Os dados necessários para a aplicação do modelo IVE haviam sido coletados anteriormente em São Paulo. Os dados operacionais dos corredores foram obtidos junto a SPTrans e a CET. As análises foram desenvolvidas em três etapas, incluindo progressivamente novas variáveis. Inicialmente foi considerado o efeito de diferentes ciclos de condução sobre as emissões dos ônibus em corredores existentes. Na segunda etapa foi feita uma análise das situações antes e depois da implantação de um corredor (Pirituba-Lapa-Centro), focalizando os impactos sobre as emissões dos ônibus e dos demais veículos, particularmente os autos, e a importância de considerar as emissões dos veículos que passam a percorrer rotas alternativas após a implantação do corredor. Finalmente, foram analisados diferentes cenários para um corredor hipotético, variando tecnologias de ônibus e avaliando os impactos de mudanças na divisão modal, condições de tráfego e outras políticas gerais. Os resultados indicaram a possibilidade de reduções significativas de emissões de poluentes quando utilizados ônibus padrão EURO 3 ou padrão EEV movidos a GNV, bem como evidenciaram a importância de infraestrutura e condições operacionais adequadas para permitir a melhoria dos ciclos de condução dos ônibus. Entretanto, ganhos adicionais são fortemente dependentes de possíveis mudanças que afetem as condições de tráfego dos autos e demais veículos, e de medidas para reduzir emissões, tais como programas de inspeção veicular e de renovação de frota. / The dissertation investigates the influence of several factors affecting vehicular emissions in high-flow bus corridors, also named BRT Bus Rapid Transit. BRT systems are being increasingly adopted in cities around the world due to the possibility to serve high demand levels at relatively low costs when compared to rail options, offering good quality of service and presenting a potential to reduce emissions. Three categories of factors are considered: (i) those directly related to the bus corridor (infrastructure design, technological and operational choices); (ii) those indirectly affected by the implementation of the corridor (such as impacts on average speed of other vehicles, particularly autos, rerouting and the potential for modal change); and (iii) factors related to general policies (such as changes in fuel type or the adoption of vehicle inspection programs). Emissions were estimated using two alternative procedures. The preferred alternative was to use the IVE International Vehicle Emission model, which bases emission estimates on the vehicle driving cycle (the time profile of speed, measured second by second). In other cases, estimates used the results of a series of emissions measurements conducted by IPT Institute of Technological Research of São Paulo for different bus technologies, operating on standard driving cycles. The developers of IVE have collected data about the technological characteristics and driving cycles of the fleet in São Paulo. Data about operations in bus corridors in São Paulo were obtained from SPTrans and CET, the local agencies responsible for bus and traffic operations. The analysis was performed in three stages, progressively extending the variables and factors included. First, the effect on bus emissions of possible changes in driving cycles in four important existing bus corridors in São Paulo was considered. A before and after analysis of a selected bus corridor (Pirituba Lapa Centro) was conducted in the second stage, looking at the impacts on emissions when other vehicles are considered, particularly autos, and highlighting the importance of taking into account vehicles that change to alternative routes after the implementation of the corridor. Finally, different scenarios were analyzed for a hypothetical corridor, varying bus technologies and considering possible impacts of changes in modal choice, traffic conditions, and other general policies. The results indicate the potential for significantly reducing pollutant emissions when Euro 3 bus technologies or enhanced GNV buses are used, as well as the important effect of appropriate infrastructure, operational and traffic engineering measures that allow improved driving cycles for buses. However, overall gains are heavily dependent on possible changes affecting autos and other vehicles, including the impact on traffic conditions and measures to reduce emissions, such as maintenance inspection or fleet renewal programs.

De 1945 à 1966, l’évolution de l’armée de l’air française dépend en grande partie des innovations technologiques. L’objet de la présente thèse est d’expliquer comment elle a été capable, technologiquement et structurellement, de passer d’une situation où elle est jugée désuète à une situation dans laquelle elle se tient en tête du dispositif de défense nationale et se positionne comme la troisième force aérienne mondiale. Nous identifions trois périodes essentielles dans la mutation de son expertise technologique. De 1945 à 1950, elle relève plusieurs défis, à l’image de l’intensification des transferts technologiques, de l’aviation à réaction, dans le contexte naissant de la guerre froide. Pour la période 1951-1958, elle suit un cycle de modernisation accélérée malgré les guerres coloniales, sous l’impulsion de l’aide aide américaine, à l’image du développement de programmes aéronautiques et de l’utilisation de missiles. Enfin, de 1959 à 1966, l’armée de l’air s’adapte aux stratégies et aux armes nouvelles dont le nucléaire. Cette période clé aboutit à l’entrée en service du système d’armes stratégique piloté Mirage IV, dans un environnement marqué par de multiples mutations structurelles et par la sortie du commandement militaire intégré de l’OTAN. / From 1945 to 1966, the evolution of the French Air Force largely depends on technological innovations. The aim of this thesis is to analyze how it became able – both technologically and structurally – to pass from a situation in which it was considered as an old-fashioned entity to the head of the national defense system, thus establishing itself as the third Air Force power. To do so, we identify three essential periods, which illustrate its shift to develop progressively its technological expertise. From 1945 to 1950, it meets several challenges such as technological transfers and jet-powered planes in the early years of the Cold War. From 1951 until 1958, it follows a fast modernization trend in spite of the Colonial Wars, as depicted through the development of aeronautical programs and the use of missiles, in a context of American Help. From 1959 to 1966, the French Air Force then adapts to both nuclear-based weapons and strategies, such as piloted strategic armament systems Mirage IV and structural transfers taken out of the military command integrated by NATO.

La présente thèse analyse la cohérence de la politique nord-africaine de la France sous la IVe République (1946-1958). Se focalisant sur la politique d’intégration en Algérie, l’auteur prend aussi en considération les imbrications entre la question algérienne et la politique de coopération au Maroc et en Tunisie ainsi qu’avec la crise de Suez en 1956. D’un côté, il s’agit de comparer les ambitions de la France au Maghreb avec l’engagement politique et économique concret. De l’autre, l’auteur analyse le bienfondé des exigences officielles face aux données régionales, nationales et internationales. L’étude examine si, en France comme en Afrique du Nord, il y a eu une motivation suffisamment grande pour accepter les conséquences multiples de la politique poursuivie et si des alternatives crédibles ont été proposées dans le débat contemporain. Globalement, l’auteur cherche à savoir comment la présumée détermination de la IVe République à défendre l’Algérie française, quoi qu’il en coûte, s’est transformée sous la Ve République en un calcul comptable des coûts qui, finalement, mène à l’indépendance de l’Algérie en 1962. / The present thesis examines the coherence of France’s North Africa policy during the Fourth Republic (1946-1958). The author focuses on the economic dimension of the so called “integration policy” in Algeria. Furthermore, its impacts on the French relations with Morocco and Tunisia as well as on the Suez Crisis in 1956 are being analyzed. On the one hand, the study compares France’s ambitious goals in the region with its actual political and economic commitment. On the other hand, it investigates the plausibility of these goals against the background of the local, national and international situation. The author verifies if politicians and citizens were willing to accept the multiple consequences of France’s political ambitions and if realistic alternatives were proposed in the discussion at that time. Moreover, the thesis offers an explanation why the presumed great determination of the Fourth Republic to keep French Algeria whatever the cost finally turned into a sober cost-benefit analysis in the Fifth Republic which led to Algerian independence in 1962. / Die vorliegende Dissertation untersucht die Kohärenz der französischen Nordafrikapolitik in der IV. Republik (1946-1958). Der Fokus liegt auf der sogenannten Integrationspolitik in Algerien. Ferner werden deren Einflüsse auf die französischen Beziehungen mit Marokko und Tunesien und auf die Suezkrise 1956 analysiert. Dabei geht es zum einen darum, die weitreichenden Ansprüche Frankreichs in der Region dem tatsächlichen politischen und ökonomischen Engagement gegen- überzustellen. Zum anderen wird die Plausibilität der offiziellen Ambitionen vor dem Hintergrund der regionalen, nationalen und internationalen Rahmenbedingungen überprüft. Damit verbunden sind die Fragen nach der Bereitschaft in Politik und Gesellschaft, die vielfältigen Konsequenzen der Nordafrikapolitik zu tragen, und nach alternativen Handlungsoptionen zu den getroffenen Ent- scheidungen. Darüber hinaus erforscht die Studie, wie aus der von großer Entschlossenheit geprägten Maxime der IV. Republik, Französisch-Algerien um jeden Preis zu verteidigen, in der V. Republik eine dem Anschein nach nüchterne Abwägung von Kosten und Nutzen zugunsten der algerischen Unabhängigkeit im Jahr 1962 werden konnte.

Le Comité National des Appellations d’Origine (CNAO), forme première de l’Institut National des Appellations d’Origine (INAO), voit officiellement le jour avec le décret-loi du 30 juillet 1935. Sa création coïncide avec l’établissement d’un nouveau régime, d’une nouvelle norme de qualité pour les vins fins, l’Appellation d’Origine Contrôlée (AOC). L’objectif de cette recherche, en prenant pour terrain d’étude cette institution, est de comprendre les caractéristiques de la normalisation des vins fins entre 1935 et la fin des années 1960, ainsi que les interactions à l’oeuvre entre la sphère publique, l’Etat, et un secteur professionnel, une filière économique, constitué par définition d’acteurs privés. Pour atteindre le but fixé, le propos se structure autour de trois parties, établies selon une logique chronologique. La première partie présente la période originelle de l’institution, c’est-à-dire celle du Comité National des Appellations d’Origine durant l’Entre-deux-guerres. Elle correspond au temps de fondation de l’organisme, d’invention et de développement du système des AOC. Dans un contexte de crises aussi bien politique, économique, sociale que viti-vinicole, le modèle fixe ses règles et se déploie avec rapidité sur le territoire. Au-delà du cadre élaboré, l’affirmation au sein de la profession, en dehors de ses tenants, est en revanche plus progressive et procède par étapes, en raison notamment des foyers de scepticisme, voire de réticences, à son endroit. L’absence de consensus et la multiplicité des configurations locales, en particulier du point de vue des éléments anciens d’expertise et des rapports de force entre producteurs et négociants, participent d’une inscription protéiforme de la norme et de l’élaboration d’ajustements dès ces premières années. Le second moment de l’étude, en focalisant son attention sur la période 1939-1945, est lui aussi marqué par la notion de crise.L’entrée en guerre de la France puis la mise en place du Régime de Vichy, d’un circuit du Ravitaillement et la période d’Occupation bouleversent ainsi largement l’équilibre conçu dans les dernières années de la IIIème République.L’inversion historique de la conjoncture économique de la viti-viniculture, passant d’une surproduction endémique à la pénurie, résume les bouleversements à l’œuvre. Cette période voit également le problème de la fraude rejaillir avec force et prendre une nouvelle dimension. Un mouvement s’affirme donc, de fermeture et de durcissement des règles de la norme. En parallèle, l’assise des AOC est renforcée aux dépens des AOS. Sur le plan institutionnel, le CNAO est confronté à une redéfinition globale de ses rapports à l’État et des cadres de l’organisation de la viti-viniculture. L’analyse s’interrompt en 1945, avec la Libération, afin d’établir le strict bilan de l’organisme et du régime au lendemain de la Deuxième Guerre mondiale. La troisième partie de l’étude débute une nouvelle fois par une période difficile.Marquées par un redémarrage compliqué de l’économie viti-vinicole, le décès de Joseph Capus et sa succession par le baron Le Roy, le passage du CNAO à l’INAO, les années 1945 à 1950 constituent une période charnière de l’histoire de l’institution. Du point de vue chronologique, ce dernier temps de la recherche est de loin le plus long puisqu’il s’étend, pour certains éléments de réflexion jusqu’en 1967, pour d’autre à l’horizon 1970.Des phénomènes de fonds transforment le visage de l’Institut au cours de ces vingt ans. Il s’agit notamment de la réforme de son organisation, de la réflexion sur son statut, du renouvellement de son incarnation ou de la mise en place progressive de l’Organisation Commune du Marché du vin au niveau européen. / The Comité National des Appellations d’Origine (CNAO), the first form of the Institut National des Appellations d'Origine (INAO), was formally established with the Decree-Law of 30 July 1935. Its creation coincided with the establishment of a new regime, a new quality standard for fine wines, the Appellation d’Origine Contrôlée (AOC). The objective of this research, taking field study this institution, is to understand the characteristics of the regulation of wines between 1935 and the late 1960s, and the interactions at work between the public sphere, State and professional sector, an economic sector, by definition consists of private actors. To achieve the goal, the purpose is structured around three parts, set in a chronological sense. The first part presents the original period of the institution, that is to say that the CNAO for the Between the two world wars. It is the time of the founding of the organization, invention and development of the AOC system. In the context of crises both political, economic, social, wine, the model sets its rules and unfolds quickly in the territory. Beyond the framework developed, the assertion in the profession, in addition to its proponents, however, is more gradual and proceeds in stages, partly because outbreaks of skepticism or reluctance, to his place. The lack of consensus and the multiplicity of local configurations, especially from the point of view of the old elements of expertise and power relations between producers and traders, are part of a registration protean standard and the development of adjustments from these early years. The second moment of the study, focusing its attention on the period 1939-1945, is also marked by the notion of crisis. The entry into the war of France and the establishment of the Vichy Regime, a circuit of Food and the Occupation period upset the balance largely developed in the last years of the Third Republic. The historic reversal of the economic conditions in the wine industry from an overproduction endemic shortage summarizes the changes at work. This period also saw the problem of fraud rebound strongly and take a new dimension. So says a movement, closing and tightening of the rules of the standard. In parallel, the seat of the AOC is enhanced at the expense of AOS. At the institutional level, the CNAO is facing a global redefinition of its relationship to the State frameworks and the organization of the wine industry. The analysis stops in 1945 with the release to establish a strict balance of the organisation and the regime after the Second World War. The third part of the study starts again through a difficult period. Marked by a complicated resurgence of the wine economy, the death of Joseph Capus and his succession by baron Le Roy, the passage of CNAO to INAO, the years 1945 to 1950 are a pivotal period in the history of the institution. From the chronological point of view, this third period of the research is by far the longest since it extends for some elements of reflection until 1967, for more on the horizon 1970. Phenomena funds are changing the face of the Institute over the past twenty years. These include the reform of the organization, from reflection on its status, renewal or incarnation of the gradual establishment of the common organization of the wine market at European level. The period also devotes an expansion of activities and issues of the Institute. Thus, issues such as permissions plantations in areas of AOC, monitoring or VDQS instead of tasting in the control process are now part of its concerns. These developments are in contact with one of a state and a world wine in full mutations.

La présente thèse de doctorat offre une nouvelle édition critique, traduite et commentée, du Périple de Pseudo-Scylax (hormis la description du Pont-Euxin). L’œuvre, un périple des côtes méditerranéennes, est transmise par un manuscrit du XIIIe siècle (Paris, BNF, Suppl. gr. 443) et par deux apographes de la Renaissance (München, BSB, gr. 566 e Vaticano, BAV, Pal. gr. 142) qui indiquent comme auteur Scylax de Caryanda, un personnage ayant vécu sous le règne de Darius I (522-486). Cependant différents indices ne permettent pas d’étayer telle datation et, après une longue querelle, les savants partagent aujourd’hui en général l’idée que le 338 av. J.-C. doit plutôt être indiqué comme le terminus post quem. En continuité avec ces études, notre thèse, articulée en trois parties principales (introduction, édition du texte avec traduction et commentaire), a pour but d’offrir une analyse attentive de l’œuvre afin d’apprécier à sa juste valeur le seul périple complet de la Méditerranée que l’antiquité nous ait transmis. La première partie, avec fonction d’introduction, vise à encadrer l’œuvre dans son contexte historico-politique et littéraire. Font suite à l’introduction un long chapitre sur l’histoire du texte, l’édition critique et une traduction du Périple. Enfin, la troisième et dernière partie est occupée par un commentaire dans lequel sont discutés des éléments textuels et historiques qui mettent bien en lumière l’importance et l’actualité de cette œuvre dans la civilisation occidentale. / This doctoral thesis offers a new edition, accompanied by a translation and a commentary, of the Periplous of Pseudo-Skylax (with the exception of the description of Black Sea). The text, a periplous of the Mediterranean, survives in a codex unicus (Paris, BNF, Suppl. gr. 443) and in two apographs (München, BSB, gr. 566 e Vaticano, BAV, Pal. gr. 142), that indicates Skylax of Caryanda as his author, a man who lived at the time of Darius I (522-486). However, several textual evidences have demonstrated that the identification of date and author would not be plausible and after a century-long debate, today the critics generally agree that 338 BC should be seen as the terminus post quem. Agreeing with the conclusion of these studies, this thesis, organized in three major sections (introduction, edition with translation, commentary), offers a systematic analysis of the work and aims to value the only and complete ancient periplous of the Mediterranean as the true and sole example of the genre of the time. The introduction aims to put the works in his own historical, political and literary context. Then, after the introduction and a long chapter on the history of the transmission of the works, the critical edition and the translation of the Periplous follow. The third and last section furnishes a rich commentary and analyse the textual and historical aspects of the work in order to show his value and his relevance for the western tradition.

L’Atlas saharien sud oranais où les Monts des Ksour forment une région montagneuse constituée de chaînonsallongés or ientés SO–NE. Les dépressions crétacées sont représentées par des synclinaux à fond plat surplombés par desanticlinaux pr incipalement jurassiques. Les formations gréseuses crétacées appelées « Continental Intercalaire » de la régiond’Aïn Séfra renferment une impor tante ressource en eau destinée à l’alimentation en eau potable et à l’ir r igation. L’étudehydrogéologique et l’identi fication des aquifères de la région montrent l’impor tante interconnexion ent re l’aquifère jurassiqueet le CI. La recharge naturelle des aquifères sous un climat semi-aride est le terme du bilan hydrique le plus délicat àdéterminer . La méthodologie proposée est une approche par interpolations spatiales et temporelles des données deprécipitations journalières et de températures moyennes mensuelles mesurées à une station, durant trois années repères(sèche, moyenne, humide). Elle est très « pratique » dans des r égions où les données climatiques sont limi tées et discontinuesdans l’espace et dans le temps. Son application nécessite des connaissances sur la nature du sol, la surface et l’altitude desimpluviums. Cette étude nous a permis d’estimer , à par t ir des gradients pluviométr ique et thermique, la lame d’eau tombéesur les affleurements jurassiques à une altitude moyenne de 1600 m, et les valeurs de l’évapotranspiration dans tout le bassinétudié. La pluie efficace calculée, et le débit d’alimentation de l’aquifère, par son impluvium calcaréo-gréseux en altitude etgréseux dans les dépressions, montrent que l’aquifère du Continental Intercalaire est alimenté pr incipalement par lesaffleurements du Jurassique surplombant les dépressions gréseuses, durant les années pluvieuses où les précipitationsdépassent 300 mm par an. Les caractér istiques chimiques des eaux ont fait l’objet de différentes analyses statistiques afin detenter d’expliquer l’or igine d’une minéralisation assez élevée (ent re 2000 et 4000 mg/ l). Dans une première approche,l’emploi de l’analyse en composantes pr incipales (ACP) met en évidence trois fami lles d’eau cor respondant aux t rois niveauxaquifères exploités. Dans une seconde étape, l’analyse factor ielle discr iminante croisée (AFD) caractér ise l’impor tance et ladominance des paramètres responsables de cette minéralisation, en relation avec le cadre géostructural du systèmehydrogéologique des gouttières synclinales d’Aïn Séfra ; les contacts anormaux entre les formations gréseuses du ContinentalIntercalaire et les structures diapir iques argilo-gypso-salines du Tr ias forment les pr incipales zones de contamination. Aprèsavoi r estimé la recharge efficace (qui var ie entre 0 pour une année sèche et 684 mm/ an une année humide) et identi fié lesécoulements souter rains et pour prévoir le compor tement hydrodynamique des gouttières synclinales d’Aïn Séfra, i l estpr imordial de réaliser un modèle mathématique. Nous n’avons pu réaliser que le modèle de l’unité hydrogéologique de GaretEl Kheil, vu l’indisponibilité des données sur les deux aut res unités (El Hanjir -Aïn Séfra, Aïn Séfra-Tiout). Nous avons choisi uncalcul par différences finies à l’aide d’un code simple et pratique « ASMWIN ». Afin de déterminer l’impact du changementclimatique et la surexploitation, deux scénarios d’exploitation ont été proposés : une recharge réduite de moitié (-50% : 810 6m3/ an au lieu de 16 10 6) et un débit d’exploitation doublé (+100% : 2.72 106m3/ an au lieu de 1.36 10 6). Ils nous ontrévélé que la nappe est plus vulnérable aux changements climatiques qu’à la surexploitation, ce qui nous a permis de déduireque la nappe est encore en sous-exploitée. / The Saharan Atlas Mountains, South of Oran includes the ‘Ksour Ridge’, a mountainous region compr ising SW-NEranges. Cretaceous depressions are represented by flat-bottomed synclines overhung by anticlines, mainly Jurassic. Thesandstone formations, so-called Continental Intercalary, of the Ain Sefra region contain an unconfined significant waterresource for dr inking water and ir r igation. The hydrogeological study and identification of aquifers prove the impor tantinterconnection between the Continental Intercalary and the Jurassic aquifers. In a recharge area character ized by a semiaridor an arid climate, therefore a low annual rainfall, effective rainfall is the hardiest item to estimate, as it was demonstrated byclassical monthly hydrological balance computations. The methodology proposed in this work relies on spatial and temporalinterpolations of scarce climatic data. This methodology can be used to determine the recharge flow to aquifers of these zones.The Ain Sefra’s syncline includes the sandstone aquifers of Continental Intercalary and of the Plio-Quaternary layers. Threeyears, with contrasting annual rainfalls, are chosen in this application: 1983 as dry year , 2006 as average year , and 2008 ashumid one. This application requires information about the soil nature, thickness and porosity, the sur face and the altitude ofthe recharge areas. The rainfall and the recharge flow to aquifers indicate that the pr incipal recharge areas are the Jurassicoutcrops, mainly dur ing the humid years, when the annual rainfall exceeds 300 mm. The chemical character istics of waterhave been submitted to different statistical analyses. As a fi rst approach, a pr incipal component analysis (PCA) displayed threeclusters of water cor responding to the three aquifer layers which are exploited. Discr iminant factor analysis (DFA) was usedto character ize the impor tance and to rank the parameters responsible for this high mineralization (between 2000 and 4000mg/ l), namely: system character istics (lithology), structural geology (fault and Tr iassic diapirs). After estimating the effectiverecharge (ranging between 0 for a dry year, and 684 mm/ year for a humid one) and identifying groundwater flow, and inorder to predict the hydrodynamic behavior of Ain Sefra’s syncline, it is essential to implement a mathematical model. Wewere only able to establish the model of the Garet El Kheil hydrogeological unit, given the data unavailability on the other twounits (El Hanjir -Ain Sefra, Ain Sefra-Tiout). We chose a finite difference method in permanent mode to improve knowledge ofthe hydraulic character istics of aquifer , and to evaluate a complete hydrological balance, using the simple and convenient"ASMWIN" code. Exploitation of the model made it possible to determine the impact of the pumped yields, and the weathertrends on the piezometr ic evolution of the aquifer . Two operating scenar ios have been proposed: halving recharge (-50%: 810 6 m 3 / year instead of 16 10 6) and doubling the well’s yield (+100 %: 2.72 10 6 m 3 / year , instead of 1.36 10 6). Weconclude that the groundwater resource is more vulnerable to the climate change than intensive use of aquifers, meaning thatthe aqui fer is underexploited at present.

Ce mémoire étudie un courant original de l’extrême gauche française : celui le plus souvent nommé « lambertiste » d’après le nom de son principal dirigeant, Pierre Lambert. La présente thèse examine sa genèse aux lendemains de la Libération puis son développement jusqu’en 1963. Ce groupe se constitue autour de quelques convictions comme un antistalinisme affirmé, la nécessité d’un fonctionnement rigoureux, la volonté d’agir « dans la classe » et la priorité donnée à l’action syndicale. Au cours de la période étudiée, il acquiert d’autres particularités comme l’anticléricalisme, un manque d’intérêt pour les révolutions coloniales ou la méfiance envers la modernité. Surtout, quand la direction de la IVe Internationale trotskyste prétend que le mouvement communiste international peut jouer un rôle progressiste, les lambertistes rompent avec elle. Désormais, ils ne cessent de dénoncer « les pablistes », Michel Pablo étant alors le dirigeant de la IVe. En revanche, ce courant politique se lie à une mouvance mêlant anarchistes, syndicalistes révolutionnaires et socialistes de gauche. Par ce biais, il se rapproche des réformistes, d’abord dans le domaine syndical puis, à la faveur de la guerre d’Algérie, dans la sphère politique. A la fin de la période étudiée, il est en passe de devenir un allié de la social-démocratie à l’extrême gauche. / This thesis studies a specific group of the French extreme left most often called « lambertist » after the name of its principal leader, Pierre Lambert. This research examines its genesis in the wake of the Liberation to its development until 1963. This organization is built around several convictions like an affirmed anti-stalinism, the necessity of a rigorous functioning, the will to act for the working class and the priority given to the unionist action. During the studied period, it acquires other characteristics such as anticlericalism, a lack of interest in colonial revolutions or a skepticism towards modernity. Above all, when the leadership of the fourth International trotskyist claims that the international communist movement can play a progressive role, the lambertists take their independence from these leaders. From now on, they keep criticizing the pablists, Michel Pablo being the leader of the fourth. Otherwise, the lambertists associate with a movement of anarchists, revolutionary trade unionists and left-wing socialists. In this way, they get closer to the reformists first in the trade union field, then, in favor of the Algerian war, in the political sphere. At the end of the studied period, the group is about to become an ally of social democracy at the extreme left.
