La ville est à nous ! : aménagement urbain et mobilisations sociales depuis le Moyen Âge : [colloque, Paris, 27-29 mai 2015] by Isabelle Backouche( Book )

1 edition published in 2018 in French and held by 44 WorldCat member libraries worldwide

"Si l'urbanisme, comme discipline, s'est constitué au XXe siècle, les mouvements sociaux qui remettent en cause l'aménagement urbain ont une histoire beaucoup plus longue. Ce livre s'attache aux multiples formes de mobilisations collectives qui, depuis le Moyen Âge, ont pris la ville ou, à une autre échelle, la région et le quartier, comme objet. Des Pays-Bas médiévaux à l'actuelle cité phocéenne, ce livre cerne les relations sociales qui s'élaborent lorsque des groupes voient leur espace matériel se modifier, qu'ils s'opposent aux changements ou s'engagent en faveur de transformations alternatives. En prêtant attention à la variété des cadres d'expérience des protagonistes et à celle de leurs répertoires d'action, de la consultation à la prise d'armes, ce livre cherche aussi à historiciser les résistances aux gestes de modernisation des pouvoirs publics. Ce faisant, il éclaire la question de la participation, versant institutionnalisé de l'implication des populations dans l'aménagement urbain. Il s'efforce d'en restituer les contextes concrets et leurs évolutions suivant trois grandes interrogations : qu'est-ce qu'un processus de politisation? Comment s'articulent les différents intérêts en jeu, individuels et collectifs ? Comment faire une histoire sociale des grands travaux ?"--Page 4 of cover

La création artistique en Allemagne occupée (1945-1949) : enjeux esthétiques et politiques by Journées d'études pluridisciplinaires Allemagne année zéro. Repenser la modernité artistique à l'aube de la Guerre froide( Book )

1 edition published in 2015 in French and held by 14 WorldCat member libraries worldwide

9 mai 1945 : la capitulation sans condition de l'Allemagne est signée. Le pays et Berlin sont divisés en quatre zones d'occupation par les puissances alliées : à l'Est les Soviétiques, à l'Ouest les Américains, les Britanniques et les Français. La reconstruction matérielle, mais aussi idéologique et artistique du pays est immédiatement entreprise. La cassure fondamentale qui suit la découverte et la libération des camps mène à une nécessité radicale : éliminer toutes les racines idéologiques du nazisme par un processus de ± dénazification » du peuple allemand, avant une phase de ± rééducation ». Les arts sont mis à contribution à toutes les étapes de ces processus : musique, arts graphiques, théâtre, cinéma ou encore littérature doivent exalter les nouvelles valeurs communes de démocratie et de liberté portées par les Alliés. Dans un premier temps, les esthétiques et les expériences modernes bannies et considérées comme ± dégénérées » sous le IIIe Reich sont remises à l'honneur. Mais rapidement, il apparaît que les termes ± démocratie » et ± liberté » revêtent des significations très différentes de la zone Ouest à la zone Est-allemande
L'archive-forme : création, mémoire, histoire : textes issus du VIIIe congrès de l'Afeccav, Université de Paris-Est, Marne-la-Vallée, 9-10 juillet 2012 by Association française des enseignants et chercheurs en cinéma et audio-visuel( Book )

1 edition published in 2014 in French and held by 5 WorldCat member libraries worldwide

L'Archive-forme : Création, Mémoire, Histoire analyse les usages et le statut de l'archive sous les angles esthétique, historique et sociologique. Comment expliquer ce rapprochement - impensable il y a quelques années, du moins en France - entre ces démarches? D'une part, le remploi des archives est l'une des esthétiques parmi les plus actuelles. D'autre part, la nécessité de renouveler les théories au tournant du XXe siècle n'est sans doute pas étrangère à ce retour massif aux archives. Bien que les approches soient diverses (génétique des oeuvres, queer studies, gender studies, visual studies, etc.), toutes donnent une certaine importance au contexte historique et social et toutes ont recours aux archives. À cela il faut ajouter le développement des réseaux sociaux par lesquels leur exploitation est devenue un phénomène de mode
L'avenir de la mémoire : patrimoine, restauration et réemploi cinématographiques by Fernand Dumont( Book )

1 edition published in 2013 in French and held by 4 WorldCat member libraries worldwide

La question de la conservation, de la restauration et de la diffusion du patrimoine cinématographique et audiovisuel devient de plus en plus cruciale. Des pans entiers de l'histoire du cinéma demeurent toujours difficiles d'accès et sont souvent menacés de disparition. Que faire de ces gisements de films et de documents audiovisuels que les archives ont de moins en moins les ressources et la possibilité de faire connaître? Où commence et où s'arrête la notion de patrimoine filmique? Quels sont les critères de pertinence qui mènent une cinémathèque ou une archive à favoriser la restauration de telle oeuvre plutôt que telle autre? Comment la redécouverte de certains corpus de films contribue à modifier notre connaissance de l'histoire du cinéma? Quelle influence la conservation et la patrimonialisation du cinéma a eu sur les créateurs de cinéma? Comment ces oeuvres participent d'une forme de valorisation singulière du patrimoine filmique?
Médecine et santé des voyageurs transocéaniques français à l'époque moderne (XVIème-XVIIIème siècle) by Guillaume Linte( )

3 editions published in 2019 in French and held by 4 WorldCat member libraries worldwide

The first French overseas maritime expeditions were part of a larger movement of European oceanic expansion. The new era which is opening for the history of the maritime fact in the West is marked by the appearance of a new experience : the transoceanic voyage.The purpose of this research is : (1) To establish the conditions under which transoceanic travel takes place during the early modern period, emphasizing the plural nature of this experience. (2) To understand the conditions that are leading to the emergence of a discourse on the health of transoceanic travellers in France, through its forms, influences and the ambitions it supports. In a modern Europe where ideas and knowledge circulate, the aim is to situate this movement within the emergence of a European literature dedicated to this issue. (3) In an analysis of the discourse on the health of transoceanic travellers, as well as its evolution during the early modern era. Based on a detailed reading of medical or technical sources, this research reveals how ideas and theories about diseases contracted during crossings or overseas stays are constructed. (4) To study the evolution of care and risk prevention practices. Assistance during overseas expeditions presents itself as a singularity during the early modern period, both by its actors and by its adaptations.Through a dialogue between the fields of the history of medicine and science, with those of the history of the maritime fact and the colonial worlds, this research attempts to reveal the conditions of the emergence of new medical knowledge

Le système alimentation/excrétion des territoires urbains : régimes et transitions socio-écologiques by Fabien Esculier( )

2 editions published in 2018 in French and held by 3 WorldCat member libraries worldwide

Nutrition and excretion are fundamental physiological needs for all human beings. Analysis of their materiality, from the cellular scale up to the great planetary-scale biogeochemical cycles, shows that nutrition and excretion form a system. The focus of our study is the sustainability of the nutrition/excretion systems of urban areas, which we have sought to assess by analysing substance flows. The most relevant of these substances seems to be nitrogen, so by assessing urban nitrogen flows we can characterise the different possible socioecological regimes and their sustainability. We identify a wide diversity of nutrition/excretion systems depending on the places and eras considered. We propose to distinguish them in terms of their circularity, in other words by the rate at which nitrogen from excreta returns to agricultural land. Using the Paris urban area as our case study, we show that its nutrition/excretion system became increasingly circular in the 19th century, reaching maximum circularity right at the start of the 20th century, before becoming steadily more linear in the course of the 20th century. In these early years of the 21st century, the nutrition/excretion system of the Paris urban area is essentially linear, and still generates significant pollution at both local and global scales. Its environmental footprint is exacerbated by a diet that is very protein rich, mostly animal in origin, and by the non-consumption of a significant proportion of the food produced. All these factors make it unsustainable. These characteristics are found throughout the Western world and raise questions about the possibility of a socioecological transition to sustainable systems of nutrition and excretion. Since the 1990s, initially in Sweden, followed by Nordic and German-speaking Europe, awareness has been growing of the role of urine. Urine is responsible for three-quarters of urban nitrogenous excretions and is a safe substance: following a period of storage, it can be used as agricultural fertiliser. This new awareness has been followed by extensive experimentation and research on urine source separation. We show that this is currently the only method in the Western world to have accomplished a return to circular systems of nutrition/excretion. Urine source separation can be done in multiple ways, depending on circumstances, and conditions in France are favourable to its development, despite the sociotechnical lock-in to mixed sewage management systems. In a forward-looking scenario, we therefore explore the possibility that the Paris urban area could return to, and within a few decades even surpass, the heights of circularity that it attained during the Belle Époque. In that case, alongside a socioecological transition in the other systems - water, energy, transport - the people of this territory could establish a sustainable regime for their system of nutrition/excretion. This thesis is part of the OCAPI research and action programme (www.leesu.fr/OCAPI)
Les entreprises locales de distribution à Grenoble et Metz : des outils de gouvernement énergétique urbain partiellement appropriés by Pauline Gabillet( )

2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide

Public action, like research, is becoming increasingly interested in the relationship between cities and energy. This thesis focuses on the ways in which energy network operators participate in the development and implementation of local energy policies and in the capacity of urban political stakeholders to drive these operators in this sense. The question is approached through local public utilities (LPU) as alternative energy distribution stakeholders in France. These companies have ensured supply and distribution of electricity and sometimes gas and heat in the areas where they are present for over one hundred years. They appear today to be innovative levers to action available to cities to develop urban energy policies. Centred on urban operators, this thesis examines the cases of GEG in Grenoble and UEM in Metz. Despite their local roots, LPUs have only in recent years granted an important place in their business strategies to the urban scale. The sectoral and centralised organisation of the electricity public services have for a long time limited the capacities of the LPUs, impeding the emergence of approaches specific to their particular areas. Reconfigurations of the economic model which impose liberalisation cause the ELDs to constantly search for new growth sources. Seizing opportunities from emerging energy-climate policies, they are proving their great adaptability and have devised new strategies valorising to a greater extent their urban roots. These urban roots alone are not enough to make the LPUs governmental tools for urban energy policy, which supposes a capacity for initiative and control by the political stakeholders of their own objectives. Through analysis of the Grenoble and Metz examples, we demonstrate that presenting energy as a local political issue is both progressive and heterogeneous, calling into question an approach to LPU control which until now has been essentially economic and industrial. Politicisation is being hindered by the lack of energy expertise in the communes, which only very infrequently manage to integrate their energy-climate concerns into strategic plans for their local businesses. In contrast, changes in operational plans are much greater in projects which involve partnerships around energy issues: regional climate-energy plans, responses to national and European calls for public tenders, coordination of distribution networks...The analysis of an alternative regional energy model from the LPUs proposed in this thesis demonstrates that the local status of operators is insufficient for the development of urban energy governance, which also operates in the politicisation of energy issues and the development of specially adapted expertise within urban political and administrative systems

Stabilité des mousses de ciment : lien avec les propriétés rhéologiques de la pâte de ciment by Blandine Feneuil( )

1 edition published in 2018 in English and held by 2 WorldCat member libraries worldwide

Les mousses de ciment présentent d'intéressantes propriétés : une faible densité, une faible consommation de matière première et une bonne résistance thermique. Certaines propriétés finales de la mousse dépendent de sa morphologie. Pour mieux comprendre cette dépendance, on veut créer des échantillons de mousse de ciment avec une structure bien contrôlée. On crée des échantillons de mousses de ciment composés de bulles de même taille, en choisissant la quantité d'air, de ciment, d'eau et de tensioactif. Pour ce faire, on mélange d'une part une mousse aqueuse de morphologie contrôlée, stabilisée par des tensioactifs, et d'autre part une pâte de ciment. Le but de cette thèse est d'étudier comment conserver cette structure jusqu'à la prise du ciment. Tout d'abord, nous étudions d'interaction entre tensioactifs et pâte de ciment. Certains tensioactifs ne sont pas compatibles avec la solution alcaline présente dans la pâte de ciment et ne permettent pas de produire une mousse dans ces conditions. Parmi les tensioactifs compatibles avec la solution interstitielle de ciment, certains s'adsorbent sur les grains de ciment. Cette adsorption change les interactions entre grains de ciment et par conséquent, la contrainte seuil de la pâte. A faible concentration en tensioactif, la monocouche de molécules adsorbée rend les grains de ciment hydrophobes, ce qui produit une attraction hydrophobe entre grains et une augmentation de la contrainte seuil de la pâte. A forte concentration en tensioactif, les micelles adsorbées engendrent une répulsion stérique entre les grains de ciment et une chute de la contrainte seuil. Dans un deuxième temps, nous étudions l'effet des bulles d'air sur la contrainte seuil d'une pâte de ciment aérée, lorsque celle-ci contient moins de 40% d'air. Les mesures sont normalisées par la contrainte seuil de la pâte interstitielle afin d'être comparées à la littérature. Lorsque le tensioactif utilisé s'adorbe peu sur les grains de ciment, les résultats sont semblables à ceux de la littérature obtenus sur des fluides à seuil modèles. En revanche, lorsque le tensioactif utilisé a une grande affinité avec les grains de ciment, la contrainte seuil normalisée est bien au-dessus des prédictions. Notre hypothèse pour expliquer ce résultat est une modification des propriétés de surface des bulles à cause de l'adsorption des grains de ciment rendus partiellement hydrophobes par le tensioactif. Ensuite, nous nous focalisons sur la stabilité des mousses de ciment avant la prise, pour une fraction d'air de 83%. On s'intéresse tout d'abord à trois séries de mesures, en gardant pour chacune le rapport eau-sur-ciment et la taille des bulles constante. Pour chacune des trois séries, seule la contrainte seuil de la pâte de ciment est changée par l'addition de superplastifiant ou d'une grande quantité de tensioactif anionique. On obtient alors un résultat inattendu : la meilleure stabilité est observée pour des tailles de bulles relativement faibles. La comparaison avec les mesures des propriétés rhéologiques de la mousse fait penser que la bonne stabilité aux faibles contraintes seuil est due à la réorganisation des grains de ciment en un réseau granulaire plus dense. Pour aller plus loin sur l'étude de la stabilité des mousses, nous avons ensuite fait varier la taille des bulles, la rapport eau-sur-ciment et la quantité de tensioactif. Nous avons pu définir un critère de stabilité pour l'ensemble de ces mousses qui dépend de la contrainte seuil interstitielle de la pâte de ciment confinée par les bulles et de la taille des bulles. Pour finir, nous mesurons la résistance en compression de mousses de ciment et leur vitesse d'imbibition afin de corréler ces propriétés à leur structure
Devenir des micropolluants prioritaires et émergents dans les filières conventionnelles de traitement des eaux résiduaires urbaines (files eau et boues), et au cours du traitement tertiaire par charbon actif by Romain Mailler( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

The first chapter is dedicated to the conventional primary and biological treatments. Hence, removals of a wide range of priority and emerging micropollutants were assessed for primary settling, physico-chemical lamellar settling, low load activated sludge process and biofiltration. Hydrophobic compounds and metals, as well as volatile organic compounds and biodegradable pollutants are rather well eliminated by these treatments. Moreover, considering removals normalized with nitrogen removals, the physico-chemical lamellar settling + biofiltration wastewater treatment plant (WWTP) is as efficient as the primary settling + low load activated sludge WWTP, despite its lower hydraulic retention time and its higher compactness. As a complement, the analysis in 3 WWTP effluents from SIAAP of 55 pharmaceuticals and hormones (PPHs) and 6 other emerging pollutants allowed characterizing the contamination of these discharges, and highlighting the high occurrence of 14 compounds at concentrations above 100 ng/L. In the second chapter, the contamination by micropollutants of different types of Parisian sewage sludges was assessed, as well as their fate during sludge treatments. Various compounds, such as alkylphenols, linear alkylbenzene sulfonates (LAS), metals, organotins, phthalates, polybromodiphenylethers (PBDEs), perfluorinated acids (PFAs), polychlorobiphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and PPHs, were quantified in raw, centrifuged, digested, thermally dried sludges and sludge cakes (cooking + press-filtering). Some of them (LAS, metals, PCBs) are not eliminated or less than dry matter by sludge treatments resulting in a content increase, while others (alkylphenols, organotins, PBDEs, PPHs, PFAs) are more removed than dry matter by anaerobic digestion and thermal drying. Overall, anaerobic digestion is the most efficient sludge process. Finally, the detection of several pollutants in the centrifuged and condensed waters from centrifugation and thermal drying indicates that a transfer is occurring and that biodegradation and volatilization are not the only mechanism to be involved in micropollutant removal from sludge. The last chapter aimed at investigating the performance of a large scale pilot operating with powdered (PAC) or micro-grain activated carbon (µGAC), during 32 campaigns. Results showed that most of PPHs, alkylphenols, artificial sweeteners, parabens and pesticides are efficiently removed (> 80%) by activated carbon in fluidized bed at moderate doses (10-20 g/m3). Furthermore, the activated carbon dose has a great influence on performances, whether with PAC or µGAC. Then, µGAC has several operational advantages (reactivability, ease of operation, high solid retention time, no need for coagulant/flocculant addition to handle the fluidized bed) over the PAC together with similar performances at a similar fresh µGAC dose (20 gµGAC/m3 ≈ 20 gPAC/m3). In addition this type of process allows an improvement of the conventional wastewater quality parameters, especially µGAC which retains total suspended solids and eliminates totally nitrites. Finally, a correlation between micropollutant and UV-254 removals has been confirmed, suggesting that this parameter could be used as a performances indicator. The complementary laboratory scale experiments performed within this chapter allowed understanding better the PAC adsorption mechanism in wastewater. The correlation between the specific surface, the bulk density of the PAC and PPHs removal has been displayed, as well as the importance of the fresh PAC dose and the contact time. Moreover, the positive effect of FeCl3 and negative influence of the quantity and quality of organic matter on micropollutant adsorption have been observed
Compréhension des mécanismes de séchage dans les matériaux de construction : cas du plâtre by Mamadou Diaga Seck( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

Les enjeux liés aux problématiques de développement durable encouragent de plus en plus d'industriels, dans le secteur du bâtiment, à se lancer dans une politique de réduction de la consommation énergétique de leurs procédés industriels. C'est dans ce cadre qu'est menée cette étude, où nous nous intéressons au cas particulier de la fabrication des plaques de plâtre, qui de par les qualités qu'elles présentent liées à leur caractère pratique et rapide à poser (temps pour le neuf que la rénovation), sont parmi les matériaux de construction les plus utilisés à l'heure actuelle. En effet pour leur fabrication, on récupère d'abord du gypse depuis la carrière que l'on calcine pour avoir de l'hémihydrate, que l'on mélange ensuite avec de l'eau pour en faire du gypse, que nous rencontrons dans les plaques de plâtre. Cependant, pour avoir une meilleure ouvrabilité lors de la préparation, on est obligé d'ajouter une quantité d'eau excédentaire par rapport à celle que nécessite la stoechiométrie de la réaction d'hydratation - quantité qu'il faudrait évacuer par la suite par séchage. Ainsi, la fabrication des plâtre s'avère être très énergivore ; c'est tout l'intérêt de la thèse où il s'agira de mieux comprendre la physique qui régit le séchage du plâtre de façon à réduire cette surconsommation énergétique. Pour mener cette étude, nous nous sommes d'abord intéressés au cas du séchage de milieux poreux assez simples (empilement de billes de verre, tubes capillaires), nous servir ensuite de la compréhension des mécanismes physiques qui régissent le séchage de ces dits-milieux, d'une part, et des observations locales (RMN, IRM, microtomographie), d'autre part, pour expliquer les différents mécanismes physiques qui entrent en jeu lors du séchage du plâtre. Cette démarche nous a donné la possibilité d'avoir une bonne maîtrise de la physique du séchage du plâtre, c'est-à-dire l'identification des différents leviers et paramètres qui régissent sa cinétique. Ceci nous a permis de mettre en place un modèle physique pour la prédiction de cette cinétique - modèle qui peut être utilisé pour une démarche d'optimisation énergétique de la fabrication des plaques de plâtre

Étude et conception d'un encodeur vidéo H264/AVC de résolution HD sur une plateforme multicœur by Nejmeddine Bahri( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

The trend toward HD resolution in most of visual multimedia applications has involved the emergence of a large number of video compression standards such as H.264/AVC (Advanced Video Coding) and HEVC (High Efficiency Video Coding). These standards are characterized by high coding performances in terms of compression ratio and video quality compared to previous standards. However, these performances come with large computational complexities which make it difficult to meet real-time encoding for HD resolution on the most common single-core programmable processors. Moreover, as embedded systems have become increasingly used in various multimedia applications, designing an embedded software solution for the H264/AVC encoder represents another difficult challenge since we have to meet the embedded requirements in terms of hardware resources such as memory and power consumption. The new embedded systems with multicore technology represent an attractive solution to overcome these problems. In this context, this thesis is interested in exploiting the performance of the new generation of Texas Instruments multicore DSPs to design an embedded real-time H264/AVC high definition video encoder. We aim a software solution, characterized by high flexibility that allows setting all parameters (quality, bitrate etc) compared to existing IPs. This software flexibility allows also the system scalability by following the coding enhancements as the migration to the newest HEVC standard. Thus, we present the algorithmic, architectural, and structural optimizations which are applied to improve the encoding speed on a single DSP core before moving to a multicore implementation. Then, we propose parallel implementations of the H264/AVC encoder exploiting the multicore architecture of our platform and the potential parallelism in the encoding chain in order to meet real-time constraints while ensuring a good performance in terms of bitrate and video quality. We also explore the problem of resources allocation (computing resources, storage resources, communication resources) with hard execution time constraints. Finally, this thesis opens the way towards the implementation of the new HEVC video coding standard on two embedded systems in order to prepare a software solution for future research
Représentations et gestion des compétences interculturelles. Le cas de Renault by Catou Faust( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

Cette recherche doctorale vise à faire la lumière sur un paradoxe : alors que l'impact des différences culturelles sur les relations de travail est reconnu, la Gestion des Ressources Humaines n'utilise pas tous les leviers dont elle dispose pour aider ses managers à être performants dans les situations interculturelles. Notre travail s'appuie sur l'étude d'un cas unique, celui de Renault où 74 entretiens semi-directifs ont été menés dans une démarche qualitative. Les résultats mettent au jour une vision restrictive de la compétence interculturelle, qui assimile cette compétence à l'expatriation et à ceux qui l'ont vécue. Ces représentations ancrées dans l'histoire de l'internationalisation de l'entreprise influencent les pratiques de GRH et ne correspondent plus tout à fait à la réalité interculturelle de l'entreprise. En effet, notre étude révèle que, suivant la combinaison de ses dimensions, cette compétence donne lieu à une diversité de profils interculturels plus ou moins adaptés à des contextes interculturels variés. Notre contribution théorique consiste donc en une relecture du concept propre à nourrir des pratiques de GRH visant à améliorer l'adéquation entre besoins et ressources en compétences. Dans une logique nouvelle, nous proposons de renoncer à l'évaluation des compétences des individus et de concentrer l'analyse sur l'identification systématique des besoins. Notre contribution managériale porte sur la proposition de pratiques de GRH, dont des variables d'analyse de la complexité interculturelle des contextes. La relecture du concept de compétence interculturelle que nous défendons dans cette recherche peut être proposée à toute entreprise multinationale
Modélisation du comportement d'un remblai en sol renforcé sous chargement ferroviaire de type TGV by Jean-Baptiste Payeur( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

This study focuses on the numerical modeling of the Mechanically Stabilized Earth (MSE) walls behavior under High Speed Train (HST) loading. First, the state of the art in reinforced earth as well as in railway dynamics modeling is analyzed. Then we present results coming from the testing of a one-scale reinforced embankment submitted to harmonic loading. They indicate that tensile forces in reinforcements, stresses and displacements depend on loading frequency which is related to train speed. One proposes a 3D Finite Element Model (FEM) in order to numerically reproduce this experimentation. The numerical results fit reasonably well with the experimental ones, highlighting the great importance of the choice of the constitutive law for the soil, reinforcement and facing. The same model is used to locally investigate the soil/reinforcement interface behaviour during a harmonic loading in steady-state. The confining pressure presents significant variations along the reinforcement strip during the dynamic loading while tensile forces are less affected by the load. Nevertheless, the global interface stability remains acceptable compared to a static load. A second numerical model is proposed, which represents a bigger embankment. The multiphase model is used to represent the reinforced soil and moving coordinates are used to take into account the moving train. Theoretical developments of this model and its implementation into CESAR-LCPC FEM code are detailed. The results indicate that the train speed does not play a big role in the overall response of the structure, in the case of a stiff reinforcement comparable to the experimental one. If the embankment is weaker, the HST speed may be close to shear waves speed within the soil, which has significant consequences into the structure, particularly on the stability of the soil/reinforcement interface. Globally the experimental results and those coming from both numerical models present the same trends: the dynamic effect coming from the train passing leads to the in-crease of displacements and confining pressure close to the highest strips, while tensile forces are less affected by the load. This leads us to the conclusion that the train speed does not have a significant effect on the stability of MSE walls, at least for embankments having similar parameters than the experimental one. However these results strongly depend on the embankment geometry, the way to model the train and the parameters and constitutive laws chosen for the soil, the soil/reinforcement interface and the facing
Économie informelle en Haïti, marché du travail et pauvreté : analyses quantitatives by Roseman Aspilaire( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

The predominance of the informal sector in the economy of Haiti, where more than 80% of the population lives below the threshold of poverty and more than 35% unemployed, suggests links between the informal economy, poverty and the labour market. Highlight these interrelationships, requires an assessment of the informal economy, which is the subject of the four chapters of this thesis, dealing successively with the evolution of the macroeconomic situation, human capital, the informal earnings of workers, and the segmentation of the labour market.The first chapter made a diagnosis of the phenomenon according to the State of affairs of the developed theories and the evolution of the macroeconomic framework of Haiti from 1980 to 2010. And then offers a macroeconomic assessment of the informal sector as a percentage of GDP from a PLS (Partial Least Squares).Chapter two sets out the relationship between the evolution of the informal economy, deregulation and neo-liberal policies through a LISREL (Linear Structural Relations) model. We look at the impact of the budgetary, fiscal and monetary policies of the past 30 years on the informal economy. We also reassess the causes of the evolution of the informal economy generally evoked by the empirical studies (taxes, social security).In the chapter three, we analyse the micro-real dimension of the informal economy through a model of the Mincer earnings estimated by the equations logit from data in a national survey on employment and the informal economy (EEEI) in 2007. We analyse the determinants of informal gains in terms of the position of the market workers (employees, entrepreneurs and self-employed); and revenues (formal and informal) and the socio-economic characteristics of the working poor and non-poor compared to the poverty line.In chapter four, we first test the competitiveness and the segmentation of the labour market by making use of model of Roy and the expanded Roy model through an estimate a model Tobit. We use a model of Dirichlet process: first analyse the segmentation and possible informal work and market competitiveness as its determinants, according to data from the EEEI 2007; then, to distinguish the fundamental characteristics of the involuntary informal (excluded from the formal labour market) than the voluntary informal who gain comparative advantages
Etude ACV des chantiers de démolition en vue de la préservation des ressources : focus sur les procédés de transport et de décharge by Raphaël Briere( )

1 edition published in 2016 in French and held by 2 WorldCat member libraries worldwide

The preservation of natural ressources is one of the biggest concerns for the years to come. The building sector that fulfills the need of a housing for every human being requires a lot of materials. Indeed, this industry plays a crucial role. Then, it seems relevant to study the building end of life which managing can transform waste into ressources. Thanks to the Life Cycle Assessment, it is possible to evaluate the environmental impacts of demolition sites and also to estimate the potential benefits of a more durable managing. From a traditional demolition where waste separation was not or little done, we are now going to a selective demolition where waste sorting is made and the different waste categories are sent to specific installations (recycling platforms, incinerators or landfills for example). Nowadays, waste recyling is being encouraged particularly for materials where the environmental benefits come with the economic ones like for metals. Our work considered the reuse of structural elements in reinforced concrete instead of their recycling. It allows to increase their lifetime while decreasing the need in mineral ressources. The environmental relevance of this solution was studied. The second contribution deals with the data adaptation needed in LCA. During the various LCA studies done in this work, the Ecoinvent database was used. However, the provided data was often too aggregated and consisted in average data which reduces the relevance of using it in specific cases. A deep analysis of the truck transportation and the landfill processes was made as well as the adaptation needed to be coherent with the specific case of demolition sites located in France. In the case of the transport process, the empty returns were more specifically taken into account. For the landfill process, one has to deal with the differences between the french and the swiss infrastructures used as the reference ones. Thus, this data adaptation could be extended to other transport and landfill processes but also to other Ecoinvent processes in order to reinforce the reliability of LCA studies
