A exuberante presença de sensações de movimento nas obras de Claudel demonstra a possibilidade de relações entre Escultura e Dança, já que ambas trabalham com o movimento corporal, e/ou as sensações do mesmo como elemento primordial na criação expressiva.Teremos como base para a construção prática os elementos da Técnica Klauss Vianna e da Técnica Energética, cujos elementos serão utilizados como instrumentos metodológicos para a recriação das obras de Claudel no território da Dança Contemporânea. / Abstract: The main focus of this study is to develop a reflection on the creative process in dance in the possible interfaces between artistic languages - Sculpture and Dance - by analyzing the relations present in the work of sculptor Camille Claudel (France: 1864-1943) and Contemporary Dance. The lively presence of movement's sensations in the works of Claudel establishes the possibility of relations between Sculpture and Dance, as both work with the body movement, and/or the sensation of it as a key in expressive creation. As substruction, we have for the practice constructing the elements of Klauss Vianna's Technique and Energetic Technique, which fundamentals will be used as methodological tools for recreating works of Claudel in the territory of Contemporary Dance. / Mestrado / Artes Cenicas / Mestre em Artes

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The objective of this work is to understand the relation among violence, magic and technic, taking as a starting-point an hypothesis by René Girard about the real function of sacrificial mechanism as a form that society has to defend itself. Our research also seeks to trace new ways to comprehend the studied phenomena. Violence is approached since its ontological fundament till the core of its menace to social cohesion; we searched also the options human groups dispose to keep it under acceptable parameters. The institution of sacrifice in societies where there is not a sufficiently established penal system, as it presents to colective fury a comum target, personates a chance to avoid an endless cicle of vengeances, with catastrophical consequences. Even rites of passage and, especially, of cure refer to scapegoat mechanism. Magic, so, is taken in this work as an inexhaustive source of cathartical rites, that expurgate group from its intrinsic agressiveness, potentially disaggregative, reinforcing thus solidarity. Modern technic, on the other side, most of cases, instead of helping on violence deflection, has been instigating us to take it as an instrument, transforming it on a mere social engineering tool. However, violence did not just prove, once and again, being uncontrolable, but even it manipulated repeatedly the ones who tried to manipulate it. Modernity, whether through national States or their rival actors, is full of exemples. We opted to exemplify the principles of this dissertation through an analysis of the period in russian history known as Red Terror , when millions of human deaths were directly provoked by government actions. In the end, we present a possibility to control violence in modern societies. / O objetivo desse trabalho é compreender a relação existente entre violência, magia e técnica, a partir de uma hipótese apontada por René Girard sobre a real função do mecanismo sacrificial para a defesa da sociedade. Nosso estudo busca também traçar novos caminhos de compreensão para os fenômenos pesquisados. A violência é abordada desde seu fundamento ontológico até o cerne de sua ameaça à coesão social. Pesquisamos as opções de que os grupos humanos dispõem para contê-la sob parâmetros aceitáveis. A instituição do sacrifício em sociedades sem sistema penal suficientemente estabelecido, ao apresentar um alvo comum para a fúria coletiva, representa uma chance de evitar um ciclo infindável de vinganças, de consequências catastróficas. Mesmo os ritos de passagem e, principalmente, os de cura remetem ao mecanismo do bode expiatório. A magia, assim, é tomada nesse trabalho como inesgotável manancial de ritos catárticos, que expurgam o grupo de sua agressividade intrínseca, potencialmente desagregadora, reforçando com isso a solidariedade. A técnica moderna, por outro lado, na maioria dos casos, em vez de servir como auxílio no desvio da violência, tem nos instigado a instrumentalizá-la, transformando-a em mera ferramenta de engenharia social. Contudo, a violência provou mais de uma vez ser não só incontrolável, mas até mesmo manipular os que tentavam manipulá-la. A modernidade, seja através dos Estados nacionais ou de atores rivais do poder estatal, está repleta de exemplos. Optamos por exemplificar os princípios dessa dissertação através de uma análise do período da história russa conhecido como Terror Vermelho , em que milhões de mortes humanas foram provocadas diretamente por ações governamentais. Ao fim, apresentamos uma possibilidade de controle da violência em sociedades modernas.

Les processeurs multi-cœurs sont considérés de nos jours comme l'avenir des calculateurs et auront un impact important dans le calcul scientifique. Cette thèse présente une nouvelle approche de résolution des grands systèmes linéaires creux et denses, qui soit adaptée à l'exécution sur les futurs machines pétaflopiques et en particulier celles ayant un nombre important de cœurs. Compte tenu du coût croissant des communications comparé au temps dont les processeurs mettent pour effectuer les opérations arithmétiques, notre approche adopte le principe de minimisation des communications au prix de quelques calculs redondants et utilise plusieurs adaptations pour atteindre de meilleures performances sur les machines multi-cœurs. Nous décomposons le problème à résoudre en plusieurs phases qui sont ensuite mises en œuvre séparément. Dans la première partie, nous présentons un algorithme basé sur le partitionnement d'hypergraphe qui réduit considérablement le remplissage ("fill-in") induit lors de la factorisation LU des matrices creuses non symétriques. Dans la deuxième partie, nous présentons deux algorithmes de réduction de communication pour les factorisations LU et QR qui sont adaptés aux environnements multi-cœurs. La principale contribution de cette partie est de réorganiser les opérations de la factorisation de manière à réduire la sollicitation du bus tout en utilisant de façon optimale les ressources. Nous étendons ensuite ce travail aux clusters de processeurs multi-cœurs. Dans la troisième partie, nous présentons une nouvelle approche d'ordonnancement et d'optimisation. La localité des données et l'équilibrage des charges représentent un sérieux compromis pour le choix des méthodes d'ordonnancement. Sur les machines NUMA par exemple où la localité des données n'est pas une option, nous avons observé qu'en présence de perturbations systèmes (" OS noise"), les performances pouvaient rapidement se dégrader et devenir difficiles à prédire. Pour cela, nous présentons une approche combinant un ordonnancement statique et dynamique pour ordonnancer les tâches de nos algorithmes. Nos résultats obtenues sur plusieurs architectures montrent que tous nos algorithmes sont efficaces et conduisent à des gains de performances significatifs. Nous pouvons atteindre des améliorations de l'ordre de 30 à 110% par rapport aux correspondants de nos algorithmes dans les bibliothèques numériques bien connues de la littérature. / Multicore processors are considered to be nowadays the future of computing, and they will have an important impact in scientific computing. In this thesis, we study methods and algorithms for solving efficiently sparse and dense large linear systems on future petascale machines and in particular these having a significant number of cores. Due to the increasing communication cost compared to the time the processors take to perform arithmetic operations, our approach embrace the communication avoiding algorithm principle by doing some redundant computations and uses several adaptations to achieve better performance on multicore machines.We decompose the problem to solve into several phases that would be then designed or optimized separately. In the first part, we present an algorithm based on hypergraph partitioning and which considerably reduces the fill-in incurred in the LU factorization of sparse unsymmetric matrices. In the second part, we present two communication avoiding algorithms that are adapted to multicore environments. The main contribution of this part is to reorganize the computations such as to reduce bus contention and using efficiently resources. Then, we extend this work for clusters of multi-core processors. In the third part, we present a new scheduling and optimization approach. Data locality and load balancing are a serious trade-off in the choice of the scheduling strategy. On NUMA machines for example, where the data locality is not an option, we have observed that in the presence of noise, performance could quickly deteriorate and become difficult to predict. To overcome this bottleneck, we present an approach that combines a static and a dynamic scheduling approach to schedule the tasks of our algorithms.Our results obtained on several architectures show that all our algorithms are efficient and lead to significant performance gains. We can achieve from 30 up to 110% improvement over the corresponding routines of our algorithms in well known libraries.

The aim of this thesis was to create the botanic snap of the chosen locations, which were meadows, grasslands, pastures and also fallow grass areas, to determine the area coverage of three main agrobotanic species i.e. grass, herbs and clover, to process it with the statistcal software and determine the method and intensity of use and fertilization of individual locations and suggest the suitable prato-technical methods. The cenological structure of the locations has been observed and described using botanic snaps. The prato-technic method used were documented for each of the locations and evaluated the influence on the cenological structure. The research was performed in locations Vřeskovice, Čeletice, Městiště in the region Pilsen, former district of Klatovy. In each location the botanic snaps were taken from 3 areas of about 5 x 6 meters each. There were determined the area coverage of grass, herbs and clovers and calculated the mean indication value of humidity. Mean indication value of humidity is the parameter usable for determination of permanent grassland management and utilization. The data from the research was elaborated in software MS Excel. I recommend to manage the analyzed permanent grasslands as follows: 1. The meadow Vřeskovice behind the sewage cleaning station - additional sow of perennial rye grass, meadow clover and white clover. 2. The meadow Mstice - total recovery alternatively conservative prato-technic measures - manure fertilization for about 20t/ha and additional sow of meadow and white clover and grass - red fescue, blue grass and perennial ryegrass. 3. The meadow above the transformer station Vřeskovice - keep on current management od additional clovers sow. 4. The pasture Čeletice grazed by horses - keep on current management or additional sow of red fescue, tall fescue and timothy grass. 5. The meadow Městiště with combined utilization by cattle pasture and mowing - keep on current way of use. 6. The pasture Vřeskovice grazed by cattle - keep on current utilization or additional sow meadow and white clover. 7. The pasture Vřeskovice grazed by sheep - keep on the current utilization, in future after the reduction of dangerous knapweed to decrease the amount of pastured animals. 8. The fallow meadow Vřeskovice behind Petrovický neither mowed nor pastured - proposed mulching twice a year for about 1 or 2 years, then pasture or pasture of extensive cattle breed (Galloway) or sheep or periodical mowing once or twice a year. 9. The fallow meadow Vřeskovice trench at the farmhouse - leave as a fallow meadow improves the biodivesity, optionally to mow once or twice a year from estetical reasons.

The analyse that allowed to conclued that the teachers develop statistics abilities propitious to literacy on cultural level, instead of appropriate functional, of this shool segment. Maybe, influenced by the didactics books that support seeing through statistc of tecnicist, emphasising the use of tabulares record and graphics, beyond the algoritimic interpretation of conception to arithmetic s mean / A presente pesquisa tem por objetivo investigar as concepções de professores do Ensino Fundamental sobre o Pensamento Estatístico. Sob o referencial dos Componentes do Pensamento de Gal (2002), dos níveis de letramento estatístico de Shamos (1995) e das dimensões do Modelo PPDAC (Problema, Plano, Dados, Análise e Conclusão) de Wild e Pffannkuch (1999) é realizada a investigação por meio de um instrumento diagnóstico e da análise de livros didáticos de Matemática. Iniciamos este trabalho com um estudo sobre o Pensamento Estatístico, definições a ele atribuídas, componentes e habilidades necessários ao letramento estatístico. Em seguida, analisamos duas coleções de livros didáticos a luz da Organização Praxeológica (Chevallard, 1996), de modo a identificar as tarefas, técnicas e discurso teórico-tecnológico por eles privilegiados. O estudo de livros didáticos permitiu identificar, no ensino atual, a abordagem tecnicista da Estatística no Ensino Fundamental. Para investigar a concepção dos professores, bem como a influência do livro didático em sua prática docente, aplicamos um questionário para 20 professores de Matemática do Ensino Fundamental e Médio de escolas de Belo Horizonte. Os resultados foram submetidos à análise auxiliada pelo software C.H.I.C. (Classificação Hierárquica, Implicativa e Coesitiva). A análise permitiu inferir habilidades estatísticas propícias ao letramento no nível «cultural», ao invés do «funcional» adequado a esse segmento escolar. Possivelmente influenciado pelos livros didáticos que favorecem uma visão tecnicista da Estatística, priorizando o uso de registros tabulares e gráficos, além da interpretação algorítmica do conceito de média aritmética

La problématique entourant la mise en oeuvre, la conception et le conditionnement de micro-capteurs au sein d'une application embarquée représente un enjeu industriel majeur, consiste en un vaste ensemble de défis techniques et touche à de nombreux champs de recherche scientifiques comme d'applications commerciales. Ce mémoire de thèse compile de manière pédagogique et détaillée la conception, la réalisation et l'évaluation expérimentale d'un capteur MEMS constitué d'un simple micro-filament destiné à la mesure, mutuellement, de la température, de la pression et de l'humidité d'une ambiance gazeuse, en utilisant un même et mutuel étage de conditionnement du signal – ce qui en tant que tel constitue une méthode d'intégration particulièrement originale qui est arbitrairement référencée comme "intégration totale". Aussi, le principe physique sous jacent à ce triplet de mesurage est la diffusion par conduction de la chaleur, produite par effet Joule dans l'élément sensible, à travers l'échantillon gazeux l'environnant. Ainsi, le principe de fonctionnement consiste en ce que, la réponse transitoire d'un tel ensemble permet d'une part de mettre en évidence, simultanément et de manière diagonalisable, à une température donnée, l'influence de la pression et de l'humidité sur la conductivité thermique et la capacité calorifique du couple sonde/échantillon. D'autre part, l'élément sensible est spécifiquement prévu pour que dans les conditions initiales du régime transitoire de l'échauffement, sa résistance électrique ne soit sensible qu'à la seule température ambiante, indépendamment des deux mesurandes. / Integration of micro sensors within an embedded system is a challenging task in terms of commercial application and deals with many fields of research. This report compiles a novel methodology of multi-sensor integration, from the design to the experimental evaluation. The reported MEMS gas sensor is made from a resistive micro-wire. It is designed to the sensing of temperature, pressure and humidity of a gaseous sample, at the same time, in using only a single sensing part as well as a single conditioning principle – which is by itself a new feature arbitrarily called "total integration". The physical principle involved here is heat-diffusion, where heat is produced by Joule effect within the resistive sensing part, sinking through the gaseous sample. The key is that the transient response of such a sensor enables the reading of both the sample thermal conductivity and heat capacity, depending on both humidity and pressure at a given temperature, the later being only depending upon the initial response of the sensor transient response.

A noção de pirataria, pertencente ao vocabulário humano desde a Antiguidade, ganha novos sentidos no atual período histórico. Neste período da globalização, o modo de produção capitalista e o meio técnico-científico-informacional se tornaram planetários. Consolida-se, portanto, uma mesma base técnica do funcionamento das sociedades nos distintos territórios, acompanhada da globalização de normas de controle cada vez mais rígidas, como se procura mostrar, neste trabalho, a partir da expansão do sistema de patentes e de proteção de direitos intelectuais. Entretanto, as novas tecnologias informacionais e comunicacionais são progressivamente mais flexíveis e possibilitam, nos lugares onde se instalam, usos não previstos e, por isso mesmo, classificados como ilegais. Nesta pesquisa, defende-se que a expansão do meio técnico-científico-informacional no Brasil engendra novas formas de piratarias, sejam aquelas praticadas pelos agentes do circuito superior da economia urbana, sejam aquelas características do circuito inferior, de acordo com a proposição de Santos (1971; 2004 [1975]). A pirataria não pode, portanto, ser analisada como uma aberração ao processo de globalização em curso, mas, ao contrário, uma de suas manifestações mais notáveis. Assim, análises econômicas e jurídicas sobre o fenômeno, mesmo predominantes, não permitem a compreensão da totalidade dos agentes e situações envolvidos. O processo de urbanização do território combina a seletividade de objetos e informações, a desigualdade de renda e a manutenção de baixos salários, associados à ampla difusão de novas mercadorias cujo consumo é incentivado pela propaganda. Nesta situação brasileira, a pirataria, contraposta ao elevado preço das mercadorias ditas originais, tem uma função central no processo recente de modernização do território. Finalmente, almejando revelar a pirataria como um uso das técnicas e informações contemporâneas a partir dos lugares, são analisadas situações geográficas reveladoras de formas de vida e de produção baseadas na desapropriação como fonte de criação de novas economias urbanas, especialmente em São Paulo, Belém do Pará e Foz do Iguaçu - Ciudad del Este. / The notion of piracy, which has been used by human vocabulary since old times, acquires a new sense during the historic period. At this globalization period, the way of capitalist production and the informational scientific technical environment have become worldwide. It consolidates, therefore, on the same technical basis of the society functioning in distinct territories, followed for the more and more rigid world rules of control, as it is presented, on this essay, on the expansion of legal right system and the protection of the intellectual rights. However, the new informational and communicational technologies are progressively more flexible and they allow, where they are set on, non-predict uses and, for that, classified as illegals. This research takes into consideration the expansion of the informational scientific technical environment in Brazil cause new ways of piracy, those that are practiced by the agent of higher circuit of the urban economy, or those whose features of the lower circuit, according Santos proposition(1971; 2004 [1975]). The piracy cannot, therefore, be analyzed as nonstandard to the globalization process in course, but, on the contrary, one of the most remarkable manifestations. So, economic and juridical analysis on the phenomenon, predominant or not, do not allow the comprehension of the totality of the involving agents and situations. The process of urbanizing of the territory combines the selectivity of objects and information, the social inequalities and the maintenance of low incomes, combined to the enormous diffusion of the new goods whose consumption is stimulated by propaganda. In this Brazilian situation, the piracy, contrasting to the higher price of goods so called originals, has a central function on the recent process of modernization of the territory. Finally, getting into the point to reveal piracy as a use of the up-to-date technics and information from the places, they are analyzed as revealed geographical situations of life style and of the production based on embezzlement as source of creation of an urban economy, especially in São Paulo, Belém do Pará and Foz do Iguaçu - Ciudad del Este.
