La ségrégation scolaire est une question épineuse. La Cour Suprême dans sa décision du 17 mai 1954 a déclaré la ségrégation inconstitutionnelle et demande aux autorités scolaires d'admettre dans leurs établissements tous les élèves sans distinction de races, si dans plusieurs localités, tous les efforts furent entrepris dans ce sens, dans le comté de Prince Edward, les blancs poussèrent les superviseurs à fermer les écoles en 1959, lorsque le bureau de l'enseignement fut sommé de les intégrer. Elles restèrent fermées jusqu'en 1964. Seuls 8 enfants blancs s'y inscrivirent. Aujourd’hui l'école publique de Prince Edward est toujours à dominance noireThis doctoral dissertation deals with the Supreme Court’s edict of 1954 brown v. Board of education of Topeka, requiring school desegregation. If several school districts rapidly complied with that decision, the white citizens of prince Edward County, Virginia were not so obliging. For a decade they challenged the federal judiciary and refused to countenance even token desegregation. When the policy of massive resistance established by the authorities was declared unconstitutional, they refused to finance public schools in 1959 and established a private academy for white students. For four years there was not formal education for blacks in the county, and when the public schools were reopened in 1964, their enrollment was almost black. Segregation was maintained by developing a new version of the dual school system even though this arrangement was widely criticized. Today the school district is still predominantly black

Full textAbstract:
Lo Unit Commitment Problem (UCP) è un problema di programmazione matematica dove un insieme di impianti termoelettrici deve essere programmato per soddisfare la domanda di energia e altri vincoli di sistema. Il modello è impiegato da decenni per supportare la pianificazione operazionale di breve termine dei sistemi elettrici.
In questo lavoro affrontiamo il problema di risolvere UCP lineari di larga-scala per realizzare simulazioni accurate di sistemi elettrici, con i requisiti aggiuntivi di impiegare capacità di calcolo convenzionali, ad esempio i personal computers, ed un tempo di soluzione di poche ore. Il problema, sotto le medesime condizioni, è affrontato abitualmente dal nostro partner industriale RSE S.p.A. (Ricerche Sistema Energetico), uno dei principali centri ricerche industriali su sistemi energetici in Italia.
L’ottimizzazione diretta di queste formulazioni con solutori generici è impraticabile. Nonostante sia possibile calcolare buone soluzioni euristiche, ovvero con un gap di ottimalità sotto il 10%, in tempi ragionevoli per UCP di larga scala, si richiedono soluzioni più accurate, per esempio con gap sotto l’1%, per migliorare l’affidabilità delle simulazioni ed aiutare gli esperti di dominio, che potrebbero non essere familiari con i dettagli dei metodi di programmazione matematica, a supportare meglio le loro analisi.
Tra le idee che abbiamo esplorato i seguenti metodi risultano i più promettenti: una mateuristica per calcolare efficientemente buone soluzioni e due metodi esatti di bounding: column generation e Benders decomposition. Questi metodi decompongono il problema disaccoppiando il commitment degli impianti termoelettrici, rappresentati da variabili discrete, e il loro livello di produzione, rappresentato da variabili continue.
I nostri esperimenti dimostrano che il modello possiede proprietà intrinseche come degenerazione e forma della funzione obbiettivo piatta che ostacolano o impediscono la convergenza in risolutori allo stato dell’arte. Tuttavia, i metodi che abbiamo sviluppato, sfruttando efficacemente le proprietà strutturali del modello, permettono di raggiungere soluzioni quasi ottime in poche iterazioni per la maggior parte delle istanze.The Unit Commitment Problem (UCP) is a mathematical programming problem where a set of power plants needs to be scheduled to satisfy energy demand and other system-wide constraints. It has been employed for decades to support short-term operational planning of power plants. In this work we tackle the problem of solving large-scale linear UCPs to perform accurate medium-term power systems simulations, with the additional requirements of employing conventional computing power, such as personal computers, and a solution time of a few hours. The problem, under such conditions, is routinely faced by our industry partner, the Energy Systems Development department at RSE S.p.A. (Ricerche Sistema Energetico), a major industrial research centre on power systems in Italy. The direct optimization of these formulations via general-purpose solvers is impractical. While good heuristic solutions, that is with an optimality gap below 10%, can be found for large-scale UCPs in affordable time, more accurate solutions, for example with a gap below 1%, are sought to improve the reliability of the simulations and help domain experts, who may not be familiar with the details of mathematical programming methods, to better support their analysis. Among the ideas we explored, the following methods are the most promising: a matheuristic to efficiently compute good solutions and two exact bounding methods: column generation and Benders decomposition. These methods decompose the problem by decoupling the commitment of thermal plants, represented by discrete variables, and their level of production, represented by continuous variables. Our experiments proved that the model posses inherent properties as degeneracy and objective flatness which hinder or prevent convergence in state-of-the-art solvers. On the other hand, the methods we devised, by effectively exploiting structural properties of the model, allow to reach quasi-optimal solutions within a few iterations on most instances.

Full textAbstract:
La synthèse de matériaux zéolithiques est régie par de nombreux paramètres, en particulier la nature de l'hétéroélément associé au silicium et celle de l'agent organique structurant. Ainsi, l'introduction de germanium dans les milieux réactionnels ainsi que l'utilisation de structurants dérivés d'imidazole, les cations 1-éthyl-3-méthylimidazolium et 1-butyl-3-méthylimidazolium, ont permis la découverte de deux nouveaux solides microporeux nommés respectivement IM-16 et IM-20 et présentant des topologies de charpente inédites (respectivement UOS et UWY). De plus, un troisième germanosilicate poreux nommé IM-17 a été obtenu en présence du cation décaméthonium. Chacun de ces trois matériaux possède un système tridimensionnel de canaux avec des ouvertures de 8 et 10 atomes T (IM-16) ou de 10 et 12 atomes T (IM-17 et IM-20), ainsi que des unités de construction composites d4r au sein de leur charpente. Enfin, une partie importante du travail a été consacrée à l'élaboration de molécules structurantes originales (dérivés du décahydro-dicyclopenta[b,d]pyrrole) puis de leur emploi en synthèse hydrothermale. Ces essais ont permis d'obtenir divers matériaux déjà connus, parmi lesquels les zéolithes IM-12 (UTL), ITQ-7 (ISV), ITQ-17 (BEC) et ITQ-21.

Full textAbstract:
La notion de Bien et de Mal est un concept utilisé aux Etats-Unis depuis l’indépendance du pays. Cependant, l’utilisation de cette notion a pris une nouvelle dimension avec le développement et la transformation du conservatisme dans la première moitié du XIXème siècle, et qui s’est accentuée dans les dernières décennies de ce vingtième siècle. La révolution culturelle en Amérique après la seconde guerre mondiale et la lutte contre le l’empire soviétique considéré comme un « mal » par les dirigeants américains en particulier Reagan Ronald ont participé à la droitisation de l’opinion publique américaine et au triomphe du conservatisme. Cette notion sujette à différentes interprétations est aujourd’hui source de violents affrontements au niveau des Etats avec des conséquences gigantesques sur les relations internationales. Les mouvements intégristes islamistes et évangéliques ne cessent d’utiliser cette notion pour imposer leur vision politico-religieuse du monde. D’où le développement du terrorisme. Pour les théoriciens néo-conservateurs, la meilleure réponse à la question du terrorisme suite aux attentats du 11 septembre 2001 est que les Etats-Unis assument leur rôle impérial en utilisant le plus souvent le hard power. Les attaques du 11 septembre étaient selon eux, la conséquence du renoncement partiel à cet esprit hégémonique. Du conservateur Ronald Reagan au religieux George W. Bush, les néo-conservateurs, ces anciens libéraux, venus de la gauche, reconvertis au conservatisme pur et dur, obsédés par la notion de puissance ont travaillé dans l’ombre pour élaborer toute une théorie et philosophie sur le rôle de l’Amérique dans les relations internationales, sur ses valeurs traditionnelles et sur son identité nationale. En effet, depuis la défaite au Vietnam, Washington avait subi une série de revers militaires, mais, également politiques dont l’Union Soviétique avait bénéficiée. A cela s’ajoute les problèmes économiques, culturels, et sociaux. Ces adeptes de Léo Strauss, qui ont chanté les louanges de Roosevelt, voire de Truman, et qui ont été marqués par ces événements, sont devenus les apôtres de l’impérialisme et d’un nouveau messianisme dans le but de défendre les intérêts et le leadership américain. Pendant longtemps, la puissance américaine a été utilisée officiellement au service des peuples opprimés dans le cadre de l’ONU, et à titre défensif, mais avec l’administration Bush Junior on a assisté à une croisade contre l’ « axe du mal » avec la mise en œuvre de la guerre préventive, considérée par les néo-conservateurs comme une théorie reposant sur des arguments justes. L’Opération Liberté en Irak a été menée, non pas en fonction des principes philosophiques qui dictent la doctrine de la guerre juste, mais au nom de la raison du plus fort. Où l’objectif était vraisemblablement de mettre en pratique la vision idéaliste, manichéenne des néo-conservateurs et de contrôler des positions stratégiques. Son application marque un tournant dans les relations internationales. Le retour du Parti Démocrate au pouvoir avec Barack Obama, lequel symbolise l’ouverture et l’espoir aux Etats-Unis, et dans le monde n’occulte guère, au-delà de son pragmatisme, l’idée que dans la perception américaine, le Mal est partout et guette le territoire américain. D’où la nécessité de recourir à la force si nécessaire pour protéger les frontières et les intérêts vitaux américainsThe concept of Good and Evil is a concept used in the United States since the country's independence. However, the use of this concept has taken a new dimension with the development and transformation of conservatism in the first half of the nineteenth century, which accelerated in the last decades of the twentieth century. The Cultural Revolution in America after the Second World War and the fight against the Soviet empire considered as an "evil" by U. S. Officials in particular Ronald Reagan attended the rightward of the American public opinion and the triumph of conservatism. This concept subject to different interpretations is now a source of violent clashes at the state level with huge consequences on international relations. The Islamist fundamentalist and evangelical movements continue to use this concept to impose their political-religious world. Hence the development of terrorism. For theorists neoconservatives, the best answer to the question of terrorism following the attacks of September 11, 2001 is that the U. S. Face their imperial role by using the most hard power. The attacks of September 11 were in their view, the result of partial renunciation hegemonic spirit. From the conservative Ronald Reagan to the religious George W. Bush, the neo-conservatives, these former liberals from the left, converted to conservatism hardcore, obsessed by the notion of power worked behind the scenes to develop a theory and philosophy on the role of America in international relations, its traditional values and national identity. Indeed, since the defeat in Vietnam, Washington had suffered a series of military setbacks, but also policies that the Soviet Union had benefited. Add to this the economic, cultural, and social. These followers of Leo Strauss, who sang the praises of Roosevelt or Truman, and which were marked by these events, have become apostles of imperialism and a new messianism in order to defend the interests and American leadership. For years, American power has been used officially in the service of oppressed peoples in the UN framework, and defensively, but with Bush Jr. Administration has seen a crusade against the "axis of evil" with implementation of preventive war, regarded by the neo-conservatives as a theory based on correct arguments. Operation Iraqi Freedom was conducted, not by philosophical principles that dictate the doctrine of just war, but in the name of the fittest. Where the goal was probably to practice the idealistic vision, Manichean neo-conservatives and control of strategic positions. Its application is a milestone in international relationsThe return of the Democratic Party administration with Barack Obama, which symbolizes openness and hope in the U. S. And the world obscures much beyond its pragmatism, the idea that the U. S. Perception, Evil is everywhere and is watching the United States. Hence the need to use force if necessary to protect the borders and vital American interests

Full textAbstract:
Le mal est un concept, son appréhension est un acte réflexif. La question du bien et du mal qui est à l'origine de la réflexion philosophique ne se pose que dans la mesure ou l'homme croit connaitre ce qu'est le bien et ce qu'est le mal. La démocratie est le plus souvent perçue dans notre culture comme un bien, la démocratie américaine, fondée dans un contexte théologico-politique, est considérée comme un modèle ; pourtant le mal y règne. La philosophie tente de donner une forme aux angoisses, une finalité aux pulsions et une rationalité à l'histoire et, sans que le monde en soit conscient, elle créé les concepts, celui du mal comme les autres. La vertu aux États-Unis est tout d'abord confrontée à l'esclavage puis aux effets pervers de la révolution industrielle ; ces 2 défis ont été relevés par 2 philosophies : le transcendantalisme et le pragmatisme; toutes 2 ont fait leur devoir de philosophie en s'attaquant au mal, toute 2 sont des philosophies de l'expérience, de la valorisation de l'action pragmatique, toutes deux ont marqué la singularité américaine. Le mal est une partie intégrante de toute démocratie; l'Amerique, loin de s'y résigner, croit en ses vertus. Ralph Waldo Emerson n'a pas eu beaucoup d'influence sur les penseurs professionnels de son époque, mais il en a une grande sur la conscience américaine; c'est en lui que le courant libéral américain a trouvé son inspiration et c'est de lui que l'on pouvait attendre un grand sursaut contre l'esclavagisme. Le transcendantalisme éveille la conscience américaine au mal esclavagiste, le pragmatisme au mal résultant des abus du capitalisme. C'est le pragmatisme qui distingue l'Amérique contemporaine des autres nations, et c'est John Dewey qui se distingue parmi les pragmatistes. Le libéralisme américain reconnait l'influence de Marx mais insiste sur un continuum moyen-fin qui est à l'opposé de celui des marxistes. Cette option philosophique est à l'origine du rejet par les États-Unis des mouvements inspirés par le…

Full textAbstract:
Depuis des décennies. The Economist est considéré comme une référence incontournable pour tous ceux qui s'intéressent à l'actualité politique et économique internationale. The Economist apparaît comme un journal d'opinion qui vise à renforcer l'influence d'une élite possédant un pouvoir économique et culturel dans le monde. L'hebdomadaire vante souvent son objectivité, son indépendance ainsi que sa vocation internationale ; cependant, le lecteur averti perçoit The Economist comme un magazine qui n'est pas si différent des autres dans la mesure où il cherche à défendre sa cause, sa doctrine et à faire valoir sa propagande. Cette thèse tente d'analyser l'image d'une personnalité politique, le Premier ministre britannique, Tony Blair, et de mettre en relief sa politique européenne et sa relation anglo-américaine à travers unelecture critique de The Economist de mai 1997 à mai 2005. Cette étude, qui se base sur l'approche de l'analyse critique du discours, envisage de souligner l'absence de partialité de The Economist, qui défend des valeurs néolibérales et tente ainsi de répondre aux attentes des lecteurs et de défendre sa vision du mondeFor decades. The Economist has been considered as an indispensable reference for those who are interested in international, political and economic news. The Economist has established itself as a journal which aims to reinforce the elite's influence on decision-making in economics, politics and culture in the world. The weekly magazine frequently proclaims its objectivity and its independence as well as its international appeal; nevertheless, the alert reader perceives The Economist as a magazine which is not so different from the others in that it defends its own cause, advocates its own doctrine and promotes its chosen propaganda.This thesis tries to analyze the image of a political figure, the British Prime Minister Tony Blair, and to focus on his European policies and Anglo-American relations through the study of The Economist between May 1997 and May 2005. The methodology of critical discourse analysis will help to demonstrate the partiality of The Economist, which vehicles neoliberal ideas, thus fulfilling readers' expectations while defending its own vision of the world

A tese intitulada “O bem e o mal na encruzilhada do sertão: o dobrar-se e desdobrar-se da unidade em Grande sertão: veredas” tem como objetivo refletir sobre os diversos modos pelos quais o bem e o mal se manifestam na referida obra de Guimarães Rosa (1908-1967). Como ponto de partida para a interpretação do tema em Rosa, partimos de algumas considerações elaboradas por Schelling (1775-1854), tentando encontrar afinidades e particularidades no romance em relação a este filósofo. Estórias, personagens e os significativos episódios do pacto com o diabo e do duelo final no Tamanduá Tão demandam atenção especial na reflexão sobre a problemática do bem e do mal na obra de Rosa. Através deste diálogo com Schelling percebemos que a obra de Rosa nos permitiu identificar vários desdobramentos do bem e do mal. Contudo, notamos também que tais desdobramentos resguardam uma unidade essencial originária entre o bem e o mal da qual são devedores.
The thesis entitled "Good and evil at the crossroads of the hinterland: the fold and unfold of the unit in Grande sertão: veredas" aims to reflect on the various ways in which good and evil are manifested in that work of Guimarães Rosa (1908-1967). As a starting point for interpreting the theme in Rosa, we begin with some considerations elaborated by Schelling (1775-1854), trying to find common characteristics in the novel in relation to this philosopher. Stories, characters and significant episodes of the pact with the devil and the final duel in "Tamanduá Tão " require special attention in reflection on issues of good and evil in the work of Rosa. Through this dialogue with Schelling we realized that the work of Rosa allowed us to identify several consequences of good and evi. However, we also note that such consequences maintain an essential unity between good and evil, to which they are indebted.

Full textAbstract:
La définition du contrat retenue par le droit français ne permet pas une prise en compte unitaire de cette notion. En outre, les dimensions juridiques du contrat, qu’elles soient économiques ou sociologiques, sont essentielles pour les parties mais souvent ignorées par le droit. Le modèle contractuel proposé par la théorie générale n'est donc que relatif. Or c'est précisément ce constat, également réalisé en droits anglais et américain, qui a donné naissance à des théories recontextualisantes du contrat dont la théorie relationnelle d'I. Macneil. Nous inspirant des travaux de cet auteur ainsi que de ceux de H. Collins nous proposons, dans un premier temps, de remodeler la théorie générale du contrat afin de permettre l'appréhension par le droit de l’intégralité du contexte contractuel et ainsi respecter l’objet recherché par les parties. Dans un second temps, nous suggérons d'adapter les compétences et pouvoirs des juges afin de faciliter la mise en œuvre de cette relecture du contrat.

Full textAbstract:
Renewable energy plays an important role in the world. Especially wind is considered one of the most important renewable resources and is probably the fastest growing renewable energy source in the world. However, renewable energy has been exploited only to a small fraction of its potential. This is due to the existence of several types of barriers to the penetration of this kind of resources. For this reason, in recent years, is considered increasingly important the development of storage technologies, that seems to have the potential to play key role in providing renewable energy.
We develop a stochastic optimization model whereby a small energy producer aims at meeting a part of the market demand, in order to maximize his own profits. In our formulation, the producer can use both traditional energy sources and wind energy, and some specific kind of storage technology. The stochastic model represents a decision support tool, on a short time horizon, that allows to evaluate the variability of both wind resource and energy prices, and the impact of using innovative storage technologies. We focus also on the role of spinning reserve, that is requested when the producer uses an intermittent energy source.
An overview, of both renewable energy and storage technologies, is presented. Some results are shown, concerning the use of some types of storage technologies and both thermal and wind energy. In particular, it highlights how the model is proposed as a tool to evaluate the effectiveness of a storage technology.

Full textAbstract:
Monitoring and identifying the state of rangelands on a landscape scale can be a time consuming process. In this thesis, remote sensing imagery has been used to show how the process of classifying different ecological sites and states can be done on a per pixel basis for a large landscape.
Twenty-seven years' worth of remotely sensed imagery was collected, atmospherically corrected, and radiometrically normalized. Several vegetation indices were extracted from the imagery along with derivatives from a digital elevation model. Dominant vegetation components from five major ecological sites in Rich County, Utah, were chosen for study. The vegetation components were Aspen, Douglas-fir, Utah juniper, mountain big sagebrush, and Wyoming big sagebrush. Training sites were extracted from within map units with a majority of one of the five ecological sites.
A Random Forests decision tree model was developed using an attribute table populated with spectral biophysical variables derived from the training sites. The overall out-of-bag accuracy for the Random Forests model was 97.2%. The model was then applied to the predictor spectral and biophysical variables to spatially map the five major vegetation components for all of Rich County. Each vegetation class had greater than 90% accuracies except for Utah juniper at 81%. This process is further explained in chapter 2.
As a follow-on effort, we attempted to classify vegetation ecological states within a single ecological site (Wyoming big sagebrush). This was done using field data collected by previous studies as training data for all five ecological states documented for our chosen ecological site. A Maximum Likelihood classifier was applied to four years of Landsat 5 Thematic Mapper imagery to map each ecological state to pixels coincident to the map units correlated to the Wyoming big sagebrush ecological site. We used the Mahalanobis distance metric as an indicator of pixel membership to the Wyoming big sagebrush ecological site. Overall classification accuracy for the different ecological states was 64.7% for pixels with low Mahalanobis distance and less than 25% for higher distances.

Full textAbstract:
In the last decade national Power Systems faced a large increase in penetration of Renewable Energy Sources (RES) generation. In particular, the largest increase was met by Photovoltaic generation (PV) and Wind Generation (WG), both affected by substantial uncontrollability and high levels of uncertainty and volatility. As a consequence, high levels of uncertainty are transferred to Power System, thus new tools are needed, capable of analyzing RES uncertainty and use the resulting characterization in helping Power System operation.
In the present PhD work of thesis both of these topics are treated. Firstly, statistical and clustering techniques are considered in order to characterize actual WG data, coming from Spanish Power System, in particular with respect to the criticalities of the Demand of power.
In a second part, Stochastic Programming techniques are introduced in an existing Medium Term Power System Simulator. The resulting model, named sMTSIM, is able solve the large scale Unit Commitment (UC) Problem for Zonal Power Systems with high level of RES penetration. The high levels of uncertainty and volatility characterizing RES generation are taken into account by means of their statistical characterization; then the UC problem is solved by coupling Stochastic Linear Programming techniques and an heuristic technique able to reintroduce the intrinsic Mixed Integer nature of UC problem.

Si les tactiques et les objectifs des étudiants furent pour l'essentiel identiques, l'acteur social sur lequel s'appuyèrent les étudiants en vue d'effectuer leur révolution sociale et culturelle diffère fondamentalement : chaque mouvement demeura fidèle en cela aux traditions culturelles, sociales et politiques du pays où il s'élabora tradition marxiste en France ; pragmatisme et tradition abolitionniste aux Etats-UnisThe case-studies of two student rebellions which marked the year 1968, one at Nanterre (France), the other at Columbia (u. S. A. ), helps to bring out the differences and the similarities between social movements which both aimed at the elaboration of a more democratic society. If the tactics and goals of students were essentially identical in the two countries, the social actor elected by students to perform the social and cultural revolution they were calling for differs fundamentally. In this, both movement remained faithful to cultural, social and political traditions of its own country: marxist tradition in France : pragmatism and abolitionist tradition in the united states

Augmented reality (AR) has revolutionized the way people view the real world, AR has been used across a range of sectors. Recently, researchers examined the possibilities for improving user experience with augmented reality. However, there are few studies on adoption of AR users' interactions with online data resources. The aim of this study is proposing a mobile augmented reality interface for users to interact and engage with online data. The prototype is based on the framework of a PEAR (Public Engagement Augmented Reality) initiative for further AR development. PEAR framework provides an AR extension and enables users to engage with online information through AR representation [1]. This prototype was developed and implemented using Unity game engines C# and Vuforia SDK on the front-end, both NodeJS servers with MongoDB were used on the back-end. The prototype was tested and then used in a 2-week user study to analyse and validate the framework.

De nombreux problèmes de calcul numérique demandent parfois à effectuer des calculs très précis. L'étude desystèmes dynamiques chaotiques fournit des exemples très connus: la stabilité du système solaire ou l’itération à longterme de l'attracteur de Lorenz qui constitue un des premiers modèles de prédiction de l'évolution météorologique. Ons'intéresse aussi aux problèmes d'optimisation semi-définie positive mal-posés qui apparaissent dans la chimie oul'informatique quantique.Pour tenter de résoudre ces problèmes avec des ordinateurs, chaque opération arithmétique de base (addition,multiplication, division, racine carrée) demande une plus grande précision que celle offerte par les systèmes usuels(binary32 and binary64). Il existe des logiciels «multi-précision» qui permettent de manipuler des nombres avec unetrès grande précision, mais leur généralité (ils sont capables de manipuler des nombres de millions de chiffres) empêched’atteindre de hautes performances. L’objectif majeur de cette thèse a été de développer un nouveau logiciel à la foissuffisamment précis, rapide et sûr : on calcule avec quelques dizaines de chiffres (quelques centaines de bits) deprécision, sur des architectures hautement parallèles comme les processeurs graphiques et on démontre des bornesd'erreur afin d'être capables d’obtenir des résultats certainsMany numerical problems require some very accurate computations. Examples can be found in the field ofdynamical systems, like the long-term stability of the solar system or the long-term iteration of the Lorenz attractor thatis one of the first models used for meteorological predictions. We are also interested in ill-posed semi-definite positiveoptimization problems that appear in quantum chemistry or quantum information.In order to tackle these problems using computers, every basic arithmetic operation (addition, multiplication,division, square root) requires more precision than the ones offered by common processors (binary32 and binary64).There exist multiple-precision libraries that allow the manipulation of very high precision numbers, but their generality(they are able to handle numbers with millions of digits) is quite a heavy alternative when high performance is needed.The major objective of this thesis was to design and develop a new arithmetic library that offers sufficient precision, isfast and also certified. We offer accuracy up to a few tens of digits (a few hundred bits) on both common CPU processorsand on highly parallel architectures, such as graphical cards (GPUs). We ensure the results obtained by providing thealgorithms with correctness and error bound proofs

Cette thèse décrit étape par étape la construction d'un système informatique distribué multiniveau. Elle montre comment il est possible de construire un système qui garantit la sécurité de ses informations et de ses traitements, y compris contre tous les types de canaux cachés. Partant des attaques contre lesquelles nous cherchons à nous prémunir, elle introduit notre démarche en montrant la nécessité d'un modèle formel qui décrive précisement la sécurité escomptée. Ce modèle est ensuite présenté. Il énonce directement des principes qui permettent la construction de systèmes sûrs. La thèse démontre ensuite que la machine M2S (Machine Multiniveau pour la Sécurité) et le réseau développés au CERT implantent bien ces principes en réalisant les contrôles de sécurité directement dans la couche matérielle. Un système opératoire distribué (sMach) est ensuite construit au dessus de cette plate-forme matérielle sûre. Il est chargé de gérer en multiniveau les ressources du système en intégrant les contrôles de sécurité qui sont réalisés dans le matériel. Il permet la création et la manipulation de traitements tournant à différents niveaux au travers de services qui sont compatibles avec ceux du micro-noyau Mach de CMU. Ce noyau opératoire est ensuite installé sur plusieurs machines qui sont reliées les unes aux autres au travers du réseau sûr. Cet ensemble constitue le système réparti multiniveau que nous voulions construire. Finalement la thèse montre comment ce système peut être utilisé en décrivant d'abord le développement d'un système distribué de gestion de fichiers multiniveaux et ensuite la construction d'une application distribuée multiniveau.

Combinamos o teorema de Hopf-Milnor e o número de Euler de uma folheação, definido por Connes, para mostrar como a geometria da folheação influencia na topologia da variedade folheada, bem como na topologia da folheação. Além disso, exibimos uma lista de invariantes topológicos para campos vetoriais unitários em hipersuperfícies fechadas do espaço Euclidiano, e mostramos como estes invariantes podem ser empregados como obstruções a certas folheações com geometria prescrita.In this work we compute the Euler class of an umbilic foliation on a manifold with suitable curvature form. We combine the Hopf-Milnor theorem and the Euler number of a foliation, defined by Connes, in order to show how the geometry of the foliation influences the topology of the foliated space as well as the topology of the foliation. Besides, we exhibit a list of topological invariants for unit vector fields on closed Euclidean hypersurfaces, and show how these invariants may be employed as obstructions to certain foliations with prescribed geometry.

Cette thèse aborde le problème du support pour les applications distribuées coopératives. La notion de groupes de processus auxquels sont délivrés des messages est l'un des mécanismes fondamentaux de la construction de telles applications. L'état de l'art présente les différentes sémantiques pour de tels protocoles et les principales réalisations. Le protocole retenu pour l'implantation est une version dérivée du protocole d'Amoeba modifié pour le support de groupes opaques. Diverses optimisations ont aussi été ajoutées. La mise en oeuvre est basée sur une couche générique permettant de s'abstraire des dépendances système et de faciliter la réalisation de nouveaux protocoles. La réalisation initiale a été faite en mode utilisateur sur le micro-noyau Mach 3.0 et a été suivie de portages sur diverses plates-formes Unix. Cette thèse analyse en détail les performances du protocole et leur évolution en fonction de nombreux critères. Enfin, une étude fine du temps d'exécution du protocole implanté en mode utilisateur valide les choix d'implantation.

Procedurell generering är ett kraftigt verktyg för att kunna skapa en stor mängd spelvärldar utan att själv behöva manuellt designa spelplaner en och en. Med bra programmerade algoritmer kan man få tillgång till en nästan obegränsad mängd av unika spelvärldar med mycket mindre arbete. Vårt uppdrag är att skapa spellogiken och spelplansgenerering till ett spel som ska skickas in som bidrag till Swedish Game Awards[1], som är nordens största tävling för spelutveckling. Vi samarbetar med en annan grupp som ska göra Nätverk och Server-funktionalitet. Deras uppgift är att skapa en huvudserver-applikation, och ett klient/server-system där två spelare kan spela mot varandra med en av spelarna som agerar server. Slutgiltiga målet är att integrera de två olika projekteten till en slutgiltig produkt. Spelet vi tänker skapa är ett schack-baserat spel som utspelar sig i en 3D-miljö. De två spelarna kommer att ha en mängd olika enheter som de kan välja att köpa för sina pengar, kallade för credits i spelet. Spelarna använder sina enheter för att förstöra motspelarens enheter, och målet är att besegra motståndarens kung. Spelet pågår tills någon av spelarnas kungar är besegrad eller tills en av spelarna ger upp.Procedural generation is a powerful tool for creating a large set of game worlds without having to design each one individually. With the proper implementation, this can allow an almost unlimited amount of unique game worlds using far less resource and time. Our task is to create the game logic and game map generation for a game that will be entered as a contestant in Swedish Game Awards, the biggest competition for game development in the Nordic Countries. We will be working in parallel with a separate group who will be implementing the networking side of the application, where the goal is to have a server where two players can play against each other from separate end systems. As the deadline for the competition approaches, we will then combine the two projects to a finished product. The game we are creating is a chess-influenced game that takes place in a 3D world. Two players will have access to different types of units that can be purchased by the in game resource known as credits, and the main objective is to defeat the enemy king. One game session continues until either of the two kings is defeated, or one of the players surrender.

Full textAbstract:
Baltimore fait partie des grandes métropoles américaines qui se sont lancées dans le cercle vertueux du développement durable. Traditionnellement acquise aux votes démocrates, constituée d’une majorité d’Afro-Américains appartenant aux classes sociales défavorisées, et portant les profonds stigmates de la crise industrielle et des récessions économiques successives, la ville offre un terreau favorable aux expériences de gestion urbaine intégrant la notion de durabilité. Bien plus, tant du point de vue des caractéristiques économiques et démographiques que de celui de l’héritage marqué de la ségrégation, c’est la dimension sociale du développement durable et la justice environnementale qui sont en jeu. Depuis 2000, la municipalité a initié deux grands projets intégrant le développement durable dans ses dimensions de « sustainability », « livability » et « smart growth », pouvant être regroupées sous l’appellation de « green politics ». L’essentiel de ses efforts porte sur la revitalisation de deux ghettos du centre-ville tombés en complète déshérence, East Baltimore et West Baltimore. Nous concentrerons notre réflexion sur deux exemples précis de « green politics » (la réhabilitation d’une partie du ghetto d’East Baltimore avec le Grand Piano ; la Red Line, ligne de train qui doit relier les deux ghettos et des zones de friches industrielles au quartier des affaires). À partir de ces exemples, nous étudierons les modes de gouvernance mis en place et le rôle joué par les différents acteurs qui y participent (« anchor institutions », grandes fondations, acteurs publics et associations de quartier). Nous nous interrogerons sur l’émergence de formes inédites de citoyenneté façonnées par ces nouveaux modes de participation à l’aménagement urbain durable. Il s’agira de comprendre si le développement durable est conçu au service des habitants du ghetto afin de lutter contre la pauvreté et les injustices sociales et environnementales, ou si, au contraire, la racialisation de ce concept favorise la gentrification, crée de nouvelles formes de ségrégation et aboutit à la fin programmée des ghettosBaltimore is part of the big American metropolises committed in a race for sustainable development. Traditionally a democratic stronghold, with a majority of city dwellers who are poor Afro-Americans, and harshly battered by the industrial crisis and the economic recession, Baltimore City is the perfect laboratory for urban planning projects experimenting sustainable development. Furthermore, with regard to its economic and demographic characteristics and the importance of segregation in the city, the social dimension of sustainable development and the issue of environmental justice are at stake. Since 2000, the Mayor and the City Council initiated two ambitious projects integrating the various aspects of sustainable development (« sustainability », « livability » and « smart growth »), which are all belonging to « green politics ». These efforts are focused on East Baltimore and West Baltimore, two huge ghettos surrounding the financial district in the downtown area. The core of our analysis concerns two projects of green politics (the rehabilitation of a part of the East Baltimore ghetto through the Grand Piano; the Red Line, a train connecting the ghettos, some industrial wastelands and the Central Business District). Through these examples, we will put under study the types of urban governance and urban regimes at work, and the role played by the different stakeholders (« anchor institutions », philanthropic foundations, public actors and neighborhood associations). New forms of citizenship may appear with unheard modes of participation to sustainable urban planning. Sustainable development may be an opportunity to improve the living conditions in the ghetto and fight against poverty and social and environmental injustices. The seamy side of the story may be a racialization of sustainable development nourishing gentrification, creating new forms of segregation and bringing about the death of the ghettos

Full textAbstract:
Introduction : la grande majorité des arrêts cardio-respiratoires (ACR) de l’adulte sont provoqués par une cause coronaire. La survenue d’un arrêt cardiaque extra-hospitalier de cause neurologique (ACR-N), notamment de cause épileptique, est un évènement rare et peu étudié dans la littérature médicale. Objectifs : dans un premier travail, nos objectifs étaient de rapporter les modalités diagnostiques, en particulier la réalisation d'une angiographie coronarienne en première intention (iCAG), ainsi que les problématiques thérapeutiques associées, dans une population de patients avec un diagnostic final d’ACR-N. Dans un second travail, notre objectif était d’identifier les facteurs associés à la survenue d’un ACR dans une population de patients adultes pris en charge pour un état de mal épileptique convulsif (EMC). Matériel et méthodes : pour le premier travail, nous avons sélectionné les patients répondants à la définition d’un ACR-N à partir du registre régional du Centre d’Expertise de la Mort Subite (CEMS) de Paris et petite couronne (2011-2015). L’étude de l’association des variables entre les circonstances initiales de survenue de l’ACR-N et une iCAG a été réalisée à l’aide d’un modèle de régression logistique. Pour le second travail, nous avons associé des cas de patients avec un ACR compliquant la prise en charge d’un EMC (ACR-EMC), identifiés dans 17 services de réanimation médicale (2000-2015), avec 235 contrôles issus de la base de données du Centre Hospitalier de Versailles de patients pris en charge pour un EMC sans ACR (2005-2013). L’étude de l’association des variables en lien avec l’EMC et la survenue d’un ACR-EMC a d’abord été réalisée à l’aide d’un modèle de régression logistique comparant les caractéristiques des cas et de contrôles non appariés. Une analyse de sensibilité a ensuite été réalisée après appariement des cas et des contrôles. Résultats : dans le premier travail, nous avons identifié 247 patients avec un ACR-N, au sein d’une population de 3542 patients initialement réanimés avec succès d’un ACR extra-hospitalier, soit 7% des cas. Alors qu’un scanner cérébral était réalisé dans un total de 84% des cas, permettant d'identifier une cause cérébro-vasculaire chez 47% des patients, une iCAG était réalisée chez 23% des patients. La réalisation d’une iCAG était statistiquement associée à la présence d’une élévation du segment ST lors du premier enregistrement électrocardiographique (OR, 5.94; 95%CI, 2.14-18.28; P=0.0009). Huit patients recevaient un traitement anticoagulant et/ou antiagrégant plaquettaire. Dans le second travail, nous avons rapporté 49 cas de patients ayant présenté un ACR-EMC, au sein d’une population de 4438 patients hospitalisés en réanimation pour cette pathologie, soit 1,1% des cas. La réalisation d’une régression logistique multivariée en associant ces 49 cas à 235 patients contrôles a permis d’identifier 4 facteurs associés à survenue de cette complication. L’existence d’au moins une comorbidité parmi les comorbidités cardiaques, respiratoires et neurologiques (autres que l’épilepsie) était négativement associée à la survenue d’un ACR (OR, 0.28; 95%CI, 0.10-0.80, P=0.02), alors qu’une mesure de la saturation pulsée en oxygène (SpO2) < 97% à la prise en charge médicale initiale (OR, 2.66; 95%CI, 1.03-7.26, P=0.04), une cause toxique responsable de l’EMC (OR, 4.13; 95%CI, 1.27-13.53, P=0.02), et la survenue de complications précoces liées à la prise en charge médicale (OR, 11.98; 95%CI, 4.67-34.69, P<0.0001) étaient positivement associées avec l’occurrence de cette complication. Conclusion : ces éléments soulignent l’importance d’une meilleure connaissance du spectre étiologique, en particulier neurologique, des patients présentant un ACR extra-hospitalier. L’identification de ces facteurs est une étape importante afin de pouvoir proposer des modifications des stratégies de prise en charge, avec comme objectif l’amélioration du pronostic vital et fonctionnel de ces patientsObjectives: In a first work, we aimed at reporting diagnostic pitfalls and treatment issues in a population of patients with a final diagnosis of OHCA-NC. In addition, we also aimed at identifying factors associated with immediate coronary angiography (iCAG) during initial etiological diagnostic management. In a second work, our goal was to identify factors associated with the occurrence of cardiopulmonary arrest (CA) in a population of adult patients treated for convulsive status epilepticus (CSE). Material and Methods: In the first work, we performed a retrospective analysis (2011-2015) of all consecutive patients from the Paris Sudden Death Expertise Centre registry (SDEC) to identify patients with OHCA-NC. We described the early diagnostic check-up performed to identify the cause of OHCA-NC. Logistic multivariate regression was performed to identify factors between iCAG and OHCA-NC patients’ characteristics. Sensitivity analysis was carried out after multiple imputation for missing data by means of chained equations. In the second work, we collected data from consecutive patients admitted to the seventeen participating university or university affiliated intensive care units for management of successfully resuscitated (CSE-CA) complicating the initial management of CSE (2000-2015). Patients were compared with 235 controls without OHCA identified in the Centre Hospitalier de Versailles single-center registry of CSE patients (2005-2013). To identify association between factors related to CSE and CSE-CA occurrence, we first compared the cases and unmatched controls using multivariate regression. Then, sensitivity analysis was performed using a propensity score approach based on 1:1 pair matching when estimating the association between CSE and CSE-CA. Moreover, additional analyses were carried out after multiple imputation for missing data by means of chained equations. Results: In the first work, we identified 247 patients with OHCA-NC, in a population of 3542 patients initially successfully resuscitated from an out-of-hospital OHCA, corresponding to 7% of cases. While a brain Computed Tomography (CT) scan was performed in a total of 84% of cases, allowing to identify a neurovascular cause in 47% of patients, iCAG was performed in 23% of patients. We found iCAG statistically associated with the presence of an ST segment elevation during the first electrocardiographic recording (OR, 5.94; 95%CI, 2.14-18.28; P=0.0009). Eight patients received anticoagulant and / or antiplatelet therapy. In the second work, we reported 49 patients with CSE-CA, in a population of 4438 patients hospitalized in intensive care unit for CSE, corresponding to 1.1% of the cases. By multivariate analysis, having at least one comorbidity among cardiac, respiratory, and neurologic (other than epilepsy) was negatively associated with the occurrence of CSE-CA (OR, 0.28; 95%CI, 0.10-0.80, P=0.02), while pulse oximetry less than 97% on scene (OR, 2.66; 95%CI, 1.03-7.26, P=0.04), drug poisoning as the cause of CSE (OR, 4.13; 95%CI, 1.27-13.53, P=0.02), and complications during early management (OR, 11.98; 95%CI, 4.67-34.69, P<0.0001) were positively associated with the occurrence of this complication. Conclusion: These factors underline the importance of a better knowledge of the etiological spectrum, particularly neurological, of patients with out-of-hospital cardiac arrest. The identification of these elements is an important step to propose changes to management strategies, with the objective of improving the vital and functional outcome of these patients

Kasmet daugybė žmonių būna sužalojami autoįvykiuose, iš kurių dalis sužalojimų būna rimti arba pasibaigia mirtimi. Dedama vis daugiau pastangų kuriant įvairias sistemas, kurios padėtų mažinti nelaimių skaičių kelyje. Tokios sistemos gebėtų perspėti vairuotojus apie galimus pavojus, atpažindamos eismo dalyvius ir sekdamos jų padėtį kelyje. Eismo dalyvių kelyje atpažinimas iš vaizdo yra pakankamai sudėtinga, daug skaičiavimų reikalaujanti problema. Šiame darbe šiai problemai spręsti pasitelkti stereo vaizdai, nesugretinamumo žemėlapis bei konvoliuciniai neuroniniai tinklai. Konvoliuciniai neuroniniai tinklai reikalauja daug skaičiavimų, todėl jie optimizuoti pasitelkus grafikos procesorių ir OpenCL. Gautas iki 33,4% spartos pagerėjimas lyginant su centriniu procesoriumi. Stereo vaizdai ir nesugretinamumo žemėlapis leidžia atmesti didelius kadro regionus, kurių nereikia klasifikuoti su konvoliuciniu neuroniniu tinklu. Priklausomai nuo scenos vaizde, reikalingų klasifikavimo operacijų skaičius sumažėja vidutiniškai apie 70-95% ir tai leidžia kadrą apdoroti atitinkamai greičiau.Many people are injured during auto accidents each year, some injures are serious or end in death. Many efforts are being put in developing various systems, which could help to reduce accidents on the road. Such systems could warn drivers of a potential danger, while recognizing on-road vehicles and tracking their position on the road. On-road vehicle recognition on image is a complex and computationally very intensive problem. In this paper, to solve this problem, stereo images, disparity map and convolutional neural networks are used. Convolutional neural networks are very computational intensive, so to optimize it GPU and OpenCL are used. 33.4% speed improvement was achieved compared to the central processor. Stereo images and disparity map allows to discard large areas of the image, which are not needed to be classified using convolutional neural networks. Depending on the scene of the image, the number of the required classification operations decreases on average by 70-95% and this allows to process the image accordingly faster.

Full textAbstract:
L'objectif de cette thèse est de montrer le déclin de la figure du superhéros dans les films américains après le 11 Septembre. Les films de superhéros n?ont jamais été si nombreux. Jamais le moral du superhéros n'a été si bas. Ce paradoxe trouve sa meilleure illustration dans l'image double de Batman relégué au ras du sol, alors que le symbole commercial de la chauve-souris brille au firmament de Gotham City. La marchandise culturelle transcenderait donc un superhéros considérablement amoindri. Ce travail se concentre sur trois domaines en particulier : la perte de masculinité du superhéros à la fin du siècle dernier, qui amène à une confrontation symbolique entre le quarterback et la majorette, ou entre Superman et un hypothétique Everyman, et la réémergence d'un monomythe réactionnaire après 2005 ; les errances d'un Surmoi freudien affaibli, et sa relation fluctuante avec un Ça très séduisant, incarné par le superméchant du vingt-et-unième siècle ; la toile de fond sociopolitique contemporaine hostile aux exploits du superhéros, pour qui l'isothymie fukuyamienne omniprésente constitue une injuste condamnation de son action salvatrice. Icône d'une démocratie libérale qui règne désormais sur notre planète, le superhéros postmoderne semble singulièrement désadapté à la culture qui l'a vu naîtreThe main topic of this doctoral thesis is the study of the decline of the superhero icon in American films after 9/11. Superhero productions are at an all-time high, and yet, the superhero's morale is at an all-time low. This paradox is best illustrated with the dual image of Batman stuck at Ground Zero, staring up at the projection of his chevron looming large in the sky of Gotham City. The glowing merchandise transcends an otherwise sullied character. This dissertation focuses on three main realms: the superhero's loss of masculinity at the end of the twentieth century, leading to the formal opposition between the figures of the quarterback and the cheerleader, or between Superman and Everyman, and the reactionary, warpath revival which started in 2005; the travails of the flailing Superego and its shifting relationship to the almighty Id, represented by the twenty-first century glorified supervillain; and, finally, the inimical sociopolitical backdrop for the superhero's prowess, in which Fukuyama's prevalent isothymia eventually denies the superhero his just laurels. The postmodern superhero thus appears as a national misfit, also because this cultural commodity now reaches far beyond the traditional boundaries of the « American Way », to embrace an increasingly globalized market

Full textAbstract:
Spinoza, parce qu’il est à la pointe de la pensée scientifique de son époque, Freud, parce qu’il prétend fonder une nouvelle science de la nature sans se référer spécifiquement aux sciences humaines, adhèrent à un modèle épistémologique issu de la science déterministe classique. En étendant son application à l’âme humaine, tous deux ont, chacun à sa manière, bouleversé la conception de l’unité psychophysique de l’individu et proposé de nouveaux modèles de compréhension de ses rapports avec les autres et avec le monde.Or, partir de la question du corps pour remonter progressivement jusqu’à celle du mal, point névralgique de la pensée de la liberté, permet de mettre en évidence ce qui les rapproche et ce qui les sépare. Si, en situant la source de la destructivité à l’intérieur de la psychè et en dialectisant les différentes tendances qui la constituent, Freud adopte une perspective non spinoziste, sa conception de la mémoire, de la représentation, du langage, du rêve et du délire, se rapproche beaucoup de celle de Spinoza et permet d’éclairer aussi bien les virtualités que les points explicites de son système.Inversement, Spinoza, par les choix doctrinaux qui marquent l’évolution de sa pensée comme par les stratégies pédagogique et éthique qu’il met à l’œuvre dans ses textes, produit une illustration en acte de ce qui favorise la puissance de l’âme et de ce qui l’entrave. Sans créditer le mal d’une essence positive, il reconnaît néanmoins à ses principales figures : finitude, privation, crime, une efficience historique, dont la compréhension peut fonder une vigilance prophylactiqueSpinoza, at the top of the scientific thought of his time, and Freud, intending to found a new science of nature without specifically referring to human sciences, adhere to an epistemological model coming from the classical determinist science. Extending its application to the human mind, they both have, each in their own way, drastically changed the conception of the psychophysical unity of the individual and proposed new models of understanding his relationships with the others and the world.And yet, starting with the question of the body to progressively reach the question of evil so problematic for the thought of freedom makes it possible to reveal what separates and brings them closer. Setting sources of destructivity inside the psyche and giving a dialectical representation of its different constituent motions, Freud adopts a non-Spinozist perspective. But his conception of memory, representation, language, dream and delirium, gets closer to that of Spinoza and allows to throw light on potentialities as much as on the explicit points of his system. Conversely, Spinoza, marking the evolution of his thought by doctrinal choices and using pedagogical and ethical strategies in his texts, gives an acting illustration of what favours and hampers the power of the mind. Nevertheless without giving a positive essence to evil, he recognizes the historical efficiency of its main figures: finiteness, deprivation and crime whose understanding can found a prophylactic vigilance

Previous issue date: 2008-12-12The text describes the work developed in a Neonatal and Pediatric Intensive Care Unit (NPICU), whose main goal is the parents-baby link care. Although such link is of major importance for the physical and mental development of the baby, it is often threatened by the emotional complexity endured during the hospitalization. The first phase of the work was dedicated to the Observation of the Mother-Baby Relationship, Esther Bick s Method, at NPICU. I not only describe data gathered about the baby, his parents and hospital staff, but also show the consequences of the presence of the psychoanalytic observer at the Unit. After considerations about the observations period, I developed the second phase of the work, which I named Joint Therapeutic Interventions at the NPICU. The technique used in such interventions was a development of the Observation of the Mother-Baby Relationship, Esther Bick s Method. The theoretical foundations used were Melanie Klein s Projective Identification concept and its communicative function developed by W. Bion (Bion, 1962/1988), Container-Contained concept (Bion, 1962/1988) and Rêverie (Bion, 1962/1988) as well as early anxiety notion developed by E. Bick in her work The experience of the skin in early object relations (1968/1991). I highligth the importance of the presence of a psychoanalyst at NPICU, who may help diminish the aguishes proper to hospitalization, through their continent attitude and small interventions. By doing so, the psychoanalyst allows the participants of an NPICU to resume their functions, which is frequently obstructed by the emotional overload brought about by the disease or by hospitalization, so that the baby may have his path freed towards his psychic growth
O texto descreve o trabalho desenvolvido em uma Unidade de Terapia Intensiva Neonatal e Pediátrica (UTINP), cujo objetivo principal é o cuidado do vínculo pais-bebê. Este vínculo que penso ser de grande importância para o desenvolvimento físico e mental do bebê, é freqüentemente ameaçado em função da complexidade emocional vivida por todos os participantes da Unidade durante o período de internação. Na primeira etapa do trabalho aqui apresentado, dedicada à Observação da Relação Mãe-Bebê, Método Esther Bick, na UTINP, descrevo os dados colhidos que se referem ao bebê, seus pais e à equipe hospitalar, bem como exponho as conseqüências da presença do observador psicanalítico na Unidade. Após reflexões sobre o período de observação, desenvolvi a segunda etapa do trabalho que denominei Intervenções Terapêuticas Conjuntas na UTINP. A técnica empregada nessas intervenções originou-se de um desenvolvimento da Observação da Relação Mãe-Bebê, Método Esther Bick. Os fundamentos teóricos utilizados foram o conceito de Identificação Projetiva de Melanie Klein e sua função comunicativa desenvolvida por W. Bion, (Bion, 1962/1988), o conceito de Continente-Contido (Bion, 1962/1988) e Rêverie (Bion, 1962/1988), bem como as idéias de E. Bick a respeito das ansiedades precoces desenvolvidas em seu trabalho A experiência da pele em relações de objeto arcaicas (1968/1991). Saliento a importância da presença de um psicanalista na UTINP, pois sua atitude continente e pequenas intervenções podem facilitar a diminuição das angústias inerentes à situação de internação. Desta forma, o psicanalista abrirá possibilidades para que os participantes da UTINP retomem suas funções, freqüentemente obstruídas pela sobrecarga emocional da doença ou da internação, e que o bebê possa ter seu caminho desobstruído em direção ao seu crescimento psíquico

Full textAbstract:
Cette enquête est partie du constat de la déshérence du nom de guerre lors des bombardements de l’OTAN contre la Serbie pour s’affirmer lors des guerres contre l’Afghanistan (2001) et l’Irak (2003). En effet, depuis la Serbie, des locutions telles que « maintien de l’ordre international », « militarisation de l’Empire », « guerre comme ordre permanent » se proposent comme les termes analytiques de ce que, ici, on persiste à appeler guerre. Ces locutions sont néanmoins à la base de thèses contradictoires : celle de la démultiplication de la guerre (tout est guerre), et celle de son abolition pour le terrorisme ou les violences civiles. Ces deux thèses présentent un point commun : l’impossibilité de singulariser la guerre pour elle-même et une entente sur la fin de son assignation étatique. Notre réponse aux thèses de la déshérence est de deux ordres. Le premier réside dans la décision de maintenir le nom de guerre, convaincue que l’élucidation du contemporain politique et guerrier passe par sa nomination et sa qualification. Ce maintien constitue la condition d’une enquête nous permettant de connaître, selon les occurrences, ce que le mot de guerre recouvre. Pour ce faire, c’est le second aspect de notre réponse, nous avions besoin d’un dispositif d’enquête : ce sera la démarche en termes de modes politiques de guerre nous permettant de qualifier différentes occurrences de pensées de la guerre en regard des conceptions singulières de la politique qui s’y déploient. Nous avons mis en œuvre cette démarche pour les pensées de Clausewitz, de Carl Schmitt, de Mao Zedong et de l’Administration Bush (2001-2003)The present investigation

This thesis covers an implementation of an artificial intelligence (AI) system for cooperation between multiple AI-agents. It was done as a part of a master thesis in Media Technology and a master thesis in Computer Engineering at Linköping University, campus Norrköping. The aim of the project was to explore modern techniques in AI and also develop a platform where this AI is implemented for the upcoming educational purposes. The idea is that students can use the system as a base to extend, learn and implement their own AI algorithms. Based on a literature study in AI systems the decision was made to base APAC on the GOAP system, a scalable planning architecture designed for real-time control of autonomous character behavior in games. The result of the thesis is a virtual world, made in Unity3D and C#, where the system is being used by virtual agents to build a city.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorThe mapping of grain yield is the main tool for analysis of the results of the techniques of precision agriculture used. In this sense, the aim of this study was to describe the equipment and clarify the current state of the art mapping yield (Chapter I), to analyze the occurrence of similarity between maps over time using different cultures (Chapter II), and finally, determine the influence that soil properties exert on crop yields (Chapter III). In Chapter I deal with the basic equipment that composes a set of monitoring harvest, giving emphasis on yield sensors on the market, the sequence shows the possibilities of using yield maps for management areas. For analysis of yield stability (Chapter II), there were four areas with a history of monitoring four crops of soybean, corn, wheat and oats. The areas were divided by a regular grid (20 x 20 m) for each raster is assigned the value of average yield of the points that were inside. Data were normalized to enable the temporal analysis. The correlation between soil properties and productivity (Chapter III) was evaluated in an area of 88 acres using the Spearman correlation. The soil samples were taken manually auger at a depth from 0 to 0.1 m, over a regular grid (50 x 50 m). The yield values of these points were determined by averaging the sample points using different radius in three cultures. The results demonstrated the presence of yield stability, especially in areas with large variation in yield in one year. The methodology should be used with caution, especially in places where there is a tendency to homogeneity in yield. The radius sample used to determine the value of yield point has a direct influence on the values of the correlations. Increasing the radius to the sample value of 30 meters provided significant gradual increase in the values of correlations. The phosphorus was the nutrient that showed high positive correlation with yield, despite being above the levels described for the critical state.
O mapeamento da produtividade de grãos constitui a principal ferramenta de análise dos resultados das técnicas de agricultura de precisão utilizadas. Neste sentido o objetivo do estudo foi descrever os equipamentos e esclarecer o estado atual da arte de mapeamento da produtividade (capitulo I), analisar a ocorrência de similaridade entre mapas ao longo do tempo utilizando diferentes culturas (capitulo II) e, por fim, determinar a influência que os atributos do solo exercem na produtividade das culturas (capitulo III). No capítulo I são descritos os equipamentos básicos que compõe um conjunto de monitoramento de colheita, dando ênfase para os sensores de produtividade presentes no mercado, na sequencia são apresentadas as possibilidades de utilização dos mapas de produtividade para gerenciamento das áreas. Para análise da estabilidade produtiva (capitulo II), foram utilizadas quatro áreas com um histórico de monitoramento de quatro safras das culturas da soja, milho, trigo e aveia. As áreas foram divididas por uma malha quadricular (20 x 20 m), para cada quadricula se atribuiu o valor de produtividade médio dos pontos que se encontravam no seu interior. Os dados foram normalizados para possibilitar a análise temporal. A correlação entre atributos do solo e a produtividade (capitulo III) foi avaliada em uma área de 36 hectares utilizando a correlação de Spearman. As amostragens de solo foram realizadas manualmente com trado calador na profundidade de 0 - 0,1 m, através de uma malha regular (50 x 50 m). Os valores de produtividade destes pontos foram determinados através da média dos pontos utilizando diferentes raios amostrais em três culturas. Os resultados demonstraram a presença de estabilidade produtiva, sobretudo em áreas que apresentam grande oscilação na produtividade em um mesmo ano. A metodologia deve ser utilizada com cautela, principalmente em locais onde há uma tendência à homogeneidade na produtividade. O raio amostral utilizado para determinar o valor de produtividade de um ponto tem influencias diretas sobre os valores das correlações. O aumento do raio amostral até o valor de 30 metros proporcionou aumentos graduais significativos nos valores das correlações. O fósforo foi o nutriente que apresentou maiores correlações positivas com a produtividade, mesmo estando acima dos teores críticos descritos para o estado.
