Afonso Henriques (1109-1185), que se encontram nas seguintes crônicas: Crónica Geral de Espanha de 1344, preparada pelo conde D. Pedro de Barcelos, Crónica de Portugal de 1419, anônima, mas atribuída por alguns estudiosos a Fernão Lopes, e Crónica de El-Rey D. Afonso Henriques, compilada por Duarte Galvão em 1505. O objetivo do confronto é pôr em evidência três versões de séculos diferentes de uma mesma história, para, assim, tentar notar as atualizações do passado que cada cronista realiza, a despeito de estruturarem seus textos a partir do recurso da compilação. Esta interrogação específica encontra-se norteada por um objetivo mais geral que é o de indagar sobre os parâmetros do fazer histórico no final da Idade Média e, para tanto, serão desdobrados nos capítulos da dissertação alguns temas incontornáveis para se entender as especificidades desse fazer histórico: as práticas de leitura possíveis entre os cronistas, o papel da compilação na construção das suas narrativas, a verdade histórica pretendida pelos cronistas, a noção de tempo nas crônicas, os diálogos dos cronistas com o seu tempo e os objetivos que norteiam cada uma das elaborações selecionadas. Em suma, o que se pretende é entender a construção da história de D. Afonso Henriques em três tempos diferentes, levando em conta que o fazer cronístico era a forma por excelência de registro do passado do século XII ao século XV / The research has as proposal to comapare three versions fo the history of the first portuguese king, D. Afonso Henriques (1109-1185), which are found in the following chronicles: Crónica Geral de Espanha de 1344, prepared by D. Peter Barcelos’ earl, Crónica de Portugal de 1419, attributed by some writes to Fernão Lopes, and Crónica de El-Rey D. Afonso Henriques, compiled by Duarte Galvão, in 1505. The objective of the comparison is to emphasize three versions of the same history from different centuries to, thus, try to notice the updates of the past that each chronicler accomplishes, despite structuring their texts from the source of compilation. This specific inquiry is oriented by a wider objective, which is to ask about the patterns of the historic labor of the late Middle Age and, for that, some themes will be developed in the elapse of the chapters, such as: the possibilities of the chroniclers’ reading, the role of the compilation in their narratives, the historical truth pretended by the chroniclers, the time organization in the chronicles, the values of the writing time of the chronicles and the objectives of their elaborations. In sum, the wanted is to understand the construction of the history of D. Afonso Henriques in three different times, knowing that the chronicles’ labour was the form for excellence for talk about of the past, from the 12th to the 15th centuries

O preparo do canal radicular ideal relaciona-se ao processo de sanificação em conjunto com a modelagem que resulta em condições especificas para a obturação dos sistemas de canais radiculares. Com a evolução constante dos sistemas de preparo, a microtomografia computadorizada (micro-CT) se apresenta como método de pesquisa confiável que possibilita uma avaliação completa e detalhada do canal radicular. Para tanto, o objetivo deste estudo foi comparar a capacidade de modelagem do sistema ProTaper Gold (PTG) em relação ao ProTaper Next (PTN) com glide path realizado com lima K #15 ou sistema ProGlider (PG), analisando o transporte da curvatura original do canal, desgaste de dentina, aumento no volume e na superfície do canal radicular e a quantificação das superfícies não tocadas após o preparo do canal radicular em canais mesiais de molares inferiores com curvatura acentuada. A média de curvatura de todos os dentes foi de 54o. Vinte e quatro molares inferiores foram divididos em dois grupos (n=12) de acordo com o glide path realizado (com PG ou com lima K #15). A seguir, o sistema PTG foi utilizado no canal mésio-vestibular e o sistema PTN no canal mésio-lingual, criando mais dois subgrupos. Os dentes foram escaneados por meio da micro-CT antes e após o preparo. Os dados obtidos foram comparados utilizando teste ANOVA para análise de variância de dois fatores e teste Tukey para combinações múltiplas. Nos resultados, em toda extensão do canal radicular, assim como para as análises nos terços cervical, médio e apical, não houve diferença estatisticamente significativa entre os grupos quanto ao transporte do canal. Quanto à quantidade de dentina removida, o sistema PTN combinado com a lima K #15 apresentou porcentagem significativamente menor do que nos outros grupos apenas no terço médio. O percentual de aumento do volume do canal foi maior nos grupos onde o glide path foi realizado com lima K #15 em relação aos grupos com glide path realizado com PG e significativo na totalidade do canal e nas análises individualizadas para os terços cervical e médio. O percentual do aumento da área de superfície foi significativamente maior na análise da totalidade do canal e na análise individualizando o terço médio nos grupos onde o glide path foi realizado com lima K#15. Ocorreu diferença significativa e maior quantidade de paredes não tocadas no terço apical nos grupos onde foi realizado glide path com lima K#15. Diante dos resultados, é possível concluir que em todos os grupos o glide path realizado com lima K #15 ou PG, não apresentou interferência sobre o desvio da curvatura original do canal radicular, no entanto, nos grupos que o PG foi usado, houve maior quantidade de paredes tocadas na região apical. / The ideal root canal preparation is related to the process of cleaning and shaping that results in specific conditions for the filling of root canal systems. Due the constant evolution of preparation systems, microcomputed tomography (micro-CT) has been presented as a reliable method of research that possibilite a complete and detailed appraisal of the root canal. Few studies have been performed on instrumentation systems with this methodology. Therefore, the aim of this study was to compare the shaping ability of the ProTaper Gold (PTG) system and the ProTaper Next (PTN) with glide path done with K #15 file or ProGlider (PG) system, analyzing the canal transportation, quantity of dentine removed, increase in volume and surface of the root canal and the quantification of uninstrumented root canal surface after the its prepare into mesial canals of mandibular molars with severely curvature. Twenty-four mandibular molars were divided in two groups (n=12) according to the glide path accomplished (with PG or with K #15 file). After, the PTG system was used on the mesiobuccal canal and the PTN system on the mesiolingual, creating two more subgroups. The teeth were scanned by a micro-CT before and after the preparation. The obtained data were compared using ANOVA test for the variance analyzes of two factors and Tukey test for multiple combinations. In the results, on all of the root canal extension, as well as to the analysis on the cervical, middle and apical thirds, there was no statistically significant difference between the groups about the canal transportation. In terms of the quantity of dentine removed, the PTN system combined with K #15 file showed significant lower percentage than the other groups just in the middle third. The increase on percentage of the canal volume was bigger in the groups where the glide path was done with K #15 file in relation to the groups with glide path accomplished with PG and significant on the totality of the canal and on the individualized analyzes for the cervical and middle thirds. The percentage of the surface increase was significantly greater on the totality analyzes of the canal and on the one individualizing the middle third on the groups where the glide path was performed with K #15 file. There was meaningful difference and greater amount of walls uninstrumented in the apical third on the groups where glide path with K #15 file was used. In front of the results, is possible to conclude that the glide path, done with K #15 file or PG, didn\'t present interference on the deviation of the root canal original curvature to all groups; however, when PG was used, there was a greater number of walls instrumented on the apical region to both systems tested.

No. of bitstreams: 1 Almeida_FabianoCosta_M.pdf: 5847726 bytes, checksum: 145c2a03eac9f5421c57057a5a6f9cb6 (MD5) Previous issue date: 2008 / Resumo: Os instrumentos endodônticos rotatórios de Ni-Ti (limas rotatórias) são utilizados para o preparo dos condutos radiculares e apresentam características de memória de forma, alta flexibilidade e geometria variável. Apesar dessas características, quando solicitados no uso clínico endodôntico, algumas vezes, apresentam fratura no interior dos condutos radiculares tendo como conseqüência uma diminuição no período de utilização, alto custo e a presença de iatrogenias. Este trabalho tem por objetivo realizar uma análise de falha de dois tipos de instrumentos endodônticos rotatórios de Ni-Ti, ProTaper® e ProFile® do mesmo fabricante (Dentsply-Tulsa Dental-Suíça), com geometrias diferentes, utilizando algumas limas com falha em serviço, e ensaios de fadiga de limas sem uso, por flexão rotativa, visando a obtenção de referenciais de micromecanismos de fratura. Foram realizadas análises químicas, por Espectrometria de Fluorescência de raios X e por Difração de raios X, metalográfica, por microscopia óptica, e fratográfica, por microscopia eletrônica de varredura, e ensaios de microdureza e de fadiga, por flexão rotativa, nos dois tipos de limas. Os resultados mostraram que as composições químicas dos dois tipos de limas são iguais, contendo, em peso, 58% de níquel e 42% de titânio, sendo possível identificar, por metalografia, duas fases, Ti2Ni (fase secundária) e TiNi (matriz). Os níveis médios de microdureza encontrados foram de 344HV1, para a lima ProTaper, e de 330HV1, para a lima ProFile. A fratografia possibilitou a identificação de duas regiões na superfície de fratura das limas, com fratura em serviço e submetidas aos ensaios de flexão rotativa, uma correspondente à zona de fadiga, e outra, a zona de fratura final, com avéolos ou "dimples". Foi possível concluir que a falha das limas analisadas foi por fadiga. / Abstract: Rotary endodontic instruments of Ni-Ti (rotary files) are used in order to prepare endodontic dental conducts and show memory shape, high flexibility, and different designs. Although these characteristics, when used in endodontics clinic, sometimes occur fracture inside the conduct of the tooth and, as a result of that, low life, high cost, and iatrogen. The propose of this study is to realize a failure analysis of two different endodontic files, ProTaper® and ProFile®, of Ni-Ti, from the same maker and different shapes, by using some files with failure in service, and fatigue test in files, without use, in rotating bend, to obtain references in terms of micromechanisms of fracture. Were realized chemical analysis, by spectrometry of X-Ray fluorescence and X-Ray diffration, metallograthy, by optical microscopy, and fratographic, by scanning electron microscopy, and microhardness and fatigue tests, in the two types of files, ProTaper and ProFile. The results show the chemical composition of the two files are the same, with 58% of nickel and 42% of titanium, in weight, and was possible to identify, by metallography, two phases, Ti2Ni (secondary phase) and TiNi (matrix). The median levels of microhardness were 344HV1, for the ProTaper® file, and 330HV1, for the ProFile® file. It was possible to identify, by scanning electron microscopy, two different regions on the fracture surface of the files, for fracture from service and from the fatigue tests, one correspondent to the fatigue zone, and another, the final fracture, show dimples. It was possible to conclude that the failure of the analyzed files was by fatigue. / Mestrado / Materiais e Processos de Fabricação / Mestre em Engenharia Mecânica

Este trabalho surgiu com o principal objetivo de analisar como se materializou o que estava previsto na textualidade da Lei 11.161/2005 nos documentos jurídicos produzidos no Estado de São Paulo, especificamente no que se refere a sua implantação. Ao tomarmos esta lei como objeto de estudo, situamo-nos teoricamente na Análise do Discurso de linha materialista e no que nesse campo se entende como política de língua(s). Nossa pesquisa permite conhecer trajetos da memória discursiva vinculada ao ensino de línguas estrangeiras nas escolas regulares do Estado de São Paulo a partir de 1961 (ano de publicação da primeira Lei de Diretrizes e Bases da Educação Nacional). O movimento de análise que realizamos implicou a construção de um corpus com base no arquivo jurídico vinculado a três instâncias: Conselho Estadual de Educação, Secretaria da Educação do Estado e Assembleia Legislativa do Estado de São Paulo, e um trabalho de interpretação dos documentos que o compõem. Duas perguntas são norteadoras: de um lado, como são significadas as línguas estrangeiras e principalmente a espanhola e como operam certos apagamentos e deslizamentos no modo de significá-las; de outro, qual o lugar que o espanhol e que outras línguas estrangeiras ocupam no ensino regular. A análise da documentação nos leva a concluir que há uma décalage no modo de significar as línguas estrangeiras: enquanto o inglês se estabelece sólida e exclusivamente no currículo regular, o espanhol e as outras línguas estrangeiras ficam fadadas ao extracurricular este último vinculado, sobretudo, aos Centros de Estudos de Línguas que também abordamos nesta dissertação. Por fim, nas Considerações Finais algumas observações sobre a sanção da Lei 13.415/2017 que revoga a Lei do Espanhol permitem confirmar, especificamente no que se refere às línguas estrangeiras, as conclusões de nossa análise. / The main purpose of this research is to analyze how what was predicted in the textuality of the law 11.161/2005 in legal documents of São Paulo state materialized, especially concerning its enactment. Using this law as object of study, one is theoretically positioned in the Discourse Analysis of the materialist line and in what is understood, in this field, as language(s) policy(ies). The research carried out here allows us to identify the paths of the discursive memory linked to the teaching of foreign languages in regular schools in the State of São Paulo from 1961 (the year when the first Law of Guidelines and Bases of National Education was published). The analysis that was carried out implied building up a corpus based on legal files linked to three agencies: the State Education Council, the State Education Secretariat and the Legislative Assembly of the State of São Paulo, and a careful study interpreting the documents from these files. This study is guided by two questions: firstly, how foreign languages and especially Spanish are signified, and how certain deletions and slides operate in the way of signifying them and, secondly, the place that Spanish and other foreign languages occupy within regular education. The analysis of the documentation leads to the conclusion that there has been a decline in the meaning of foreign languages: while English is firmly and exclusively established in the regular curriculum, Spanish and other foreign languages are relegated to the position of \"extracurricular\" the latter linked, especially, to the Language Studies Centers, also addressed in this dissertation. Finally, after Final Considerations, some observations on the approval of Law 13.415/2017, rejecting the \"Spanish Law\", allows one to confirm the conclusions of this analysis, specifically with regard to what is referred to as foreign languages.

The diploma thesis titled "Selected aspects of domestic violence described in court files and psychological expert opinions" deals with forensic - psychological issues. The theoretical part defines domestic violence, its forms and types. There is also space for individual aspects of domestic violence, including treatises on victims and perpetrators of domestic violence, related myths and consequences. This chapter also covers the issue of how to help. A separate part deals with the court file, its content and composition. The expert opinion, its assignment and content is then devoted to the conclusion of the theoretical part. The empirical part, focused on the examination of selected aspects of domestic violence, was based on an analysis of court files containing the psychological expert opinion in cases of abuse under §198 and §199 of the Criminal code. Keywords: Domestic violence, Court files, Expert witness psychologist, Expert opinion

This study investigates the relationships between the use of a zoom tool, the terms they supply to describe the image, and the type of image being viewed. Participants were assigned to two groups, one with access to the tool and one without, and were asked to supply terms to describe forty images, divided into four categories: landscape, portrait, news, and cityscape. The terms provided by participants were categorized according to models proposed in earlier image studies. Findings of the study suggest that there was not a significant difference in the number of terms supplied in relation to access to the tool, but a large variety in use of the tool was demonstrated by the participants. The study shows that there are differences in the level of meaning of the terms supplied in some of the models. The type of image being viewed was related to the number of zooms and relationships between the type of image and the number of terms supplied as well as their level of meaning in the various models from previous studies exist. The results of this study provide further insight into how people think about images and how the manipulation of those images may affect the terms they assign to describe images. The inclusion of these tools in search and retrieval scenarios may affect the outcome of the process and the more collection managers know about how people interact with images will improve their ability to provide access to the growing amount of pictorial information.

Objetivo: A busca incessante de melhorar o preparo do canal radicular faz com que novos instrumentos sejam projetados. Porém, diversos fatores como ângulo de corte, secção transversal, conformação da ponta e conicidade influenciam NBA fratura desses instrumentos. Sendo assim, o propósito da presente investigação foi avaliar in vitro a capacidade de corte e deformação de lima rotatória F2 do sistema ProTaper Universal e da lima 25/06 do sistema EndoSequence, ambas de níqueltitânio em função do número de usos. Método: Para realização deste estudo foi utilizada uma amostra não aleatória por conveniência de dez limas rotatórias F2 do Sistema ProTaper Universal e dez limas rotatórias n 25/06 do Sistema EndoSequence. Resultados: Na análise estatística descritiva do somatório dos desgastes das limas ProTaper Universal, o coeficiente de variação foi de 8,7%, e para o EndoSequence foi de 9,12%. Quando comparada a eficiência de corte dos somatórios de desgastes não verificou-se diferença estatisticamente significante entre as limas ProTaper Universal e as EndoSequence.. As limas F2 ProTaper Universal analisadas demonstraram perda de corte progressiva a partir do primeiro uso com estatística significante até o quinto uso, enquanto as limas 25/0,6 EndoSequence também demonstraram perda de corte progressiva significante do primeiro ao quinto uso com exceção do quarto uso onde não houve perda de corte significante em relação ao terceiro uso. Acredita-se que em função do exposto acima, quando se comparou a perda de corte dos diferentes usos entre os dois grupos só houve diferença estatística significante na comparação entre o quarto uso na qual as limas EndoSequence demonstraram melhor desempenho que as limas ProTaper Universal, no restante da comparação não houve diferença estatística significante entre as limas estudadas. Quanto à deformação das limas estudadas verificou-se que não houve diferença estatisticamente significante quando observadas em microscópio eletrônico de varredura. Conclusões: Mediante a metodologia utilizada e com base nos resultados obtidos concluiu-se que as limas ProTaper e EndoSequence apresentaram capacidade de corte semelhantes; no que se refere à deformação das limas, verificou-se que entre estas duas marcas utilizadas não houve diferença estatisticamente significante. / Aim: The search to improve root canal preparation makes new instruments are designed. However, several factors such as cutting angle, cross section, forming the tip and taper influence the fracture of these instruments. Therefore, the purpose of this investigation was to evaluate in vitro the ability to cut and deformation of rotating file F2 ProTaper Universal system and file system EndoSequence of 25/06, both nickel-titanium based on the number of uses. Methods: For this study we used a non-random convenience sample of ten files rotary F2 ProTaper Universal System and ten rotary files number 25/06 of System EndoSequence. Results: In the descriptive statistical analysis of the sum of the loss of files ProTaper Universal, the coefficient of variation was 8,7%, and the EndoSequence was 9,12%. When compared to the cutting efficiency of summation of damage there was no statistically significant difference between the files ProTaper Universal and EndoSequence. The F2 ProTaper Universal files examined showed progressive loss of cut from the first use with statistically significant until the fifth use, while the 25/06 EndoSequence files also demonstrated significant progressive loss of cutting from the first to the fifth use except the forth use, where there was no loss of significant cuts in relation to the third use. It is believed that based on the last sentence, when were compared the loss of cutting of different uses between both groups, there was only one statistically significant difference in the comparison between the forth uses, where the used EndoSequence files shows better performance than the ProTaper Universal files, and the rest of the comparison was not statistically significant between the files studied. As the deformation of the files examined it was found that there was no statistically significant when seen in the scanning electron microscope. Conclusions: Using the methodology used and based on the results obtained it was concluded that the ProTaper files and EndoSequence showed similar ability to cut, in relation to deformation of files, found that between these two marks used no difference statistically significant.

La génération aléatoire d'objets combinatoires est un problème qui se pose dans de nombreux domaines de recherche (réseaux de communications, physique statistique, informatique théorique, combinatoire, etc.). Couramment, la distribution des échantillons est définie comme la distribution stationnaire d'une chaîne de Markov ergodique. En 1996, Propp et Wilson ont proposé un algorithme permettant l'échantillonnage sans biais de la distribution stationnaire. Ce dernier appelé aussi algorithme de simulation parfaite, requiert la simulation en parallèle de tous les états possibles de la chaîne. Plusieurs stratégies ont été mises en œuvre afin de ne pas avoir à simuler toutes les trajectoires. Elles sont intrinsèquement liées à la structure de la chaîne considérée et reposent essentiellement sur la propriété de monotonie, la construction de processus bornants qui exploitent la structure de treillis de l'espace d'états ou le caractère local des transitions. Dans le domaine des réseaux de communications, on s'intéresse aux performances des réseaux de files d'attente. Ces derniers se distinguent en deux groupes : ceux dont la distribution stationnaire possède une forme produit qui est facile à évaluer par le calcul et les autres. Pour ce dernier groupe, on utilise la génération aléatoire pour l'évaluation de performances. De par la structure des chaînes qui leurs sont associées, les réseaux ouverts de files d'attente se prêtent bien à la simulation via l'algorithme de simulation parfaite mais pas les réseaux fermés. La difficulté réside dans la taille de l'espace des états qui est exponentielle en le nombre de files à laquelle s'ajoute une contrainte globale à savoir le nombre constant de clients. La contribution principale de cette thèse est une nouvelle structure de données appelée diagramme. Cette structure est inspirée de la programmation dynamique et introduit une nouvelle technique de construction de processus bornant. La première partie du manuscrit est consacrée à la mise en œuvre de l'algorithme de Propp et Wilson pour des réseaux fermés n'étant pas nécessairement à forme produit. La représentation des états par un diagramme et l'opération de transition pour le processus bornant a dès lors une complexité polynomiale en le nombre de files et de clients. Cette technique est ensuite étendue aux réseaux fermés multiclasses ainsi qu'aux réseaux possédant des synchronisations. Une spécification des ensembles d'objets pouvant être représentés par un diagramme ainsi que des algorithmes agissant sur cette structure de données sont également proposés dans cette thèse. La méthode de Botzmann est une autre technique de simulation sans biais. Basée sur la combinatoire analytique, elle permet l'échantillonnage uniforme d'objets appartenant à une même classe combinatoire. Elle est employée dans la seconde partie de cette thèse afin d'échantillonner la distribution stationnaire de réseaux fermés à forme produit et pour la génération des multi-ensembles de taille fixe. Dans ce cadre, les diagrammes sont une nouvelle fois mis à profit. Enfin, la troisième partie présente les logiciels découlant des travaux présentés tout au long de ce travail, et qui implémentent les diagrammes et mettent en œuvre la simulation parfaite de réseaux fermés de files d'attente. / Random generation of combinatorial objects is an important problem in many fields of research (communications networks, theoretical computing, combinatorics, statistical physics, ...). This often requires sampling the stationary distribution of an ergodic Markov chain. In 1996, Propp and Wilson introduced an algorithm to produce unbiased samples of the stationary distribution, also called a perfect sampling algorithm. It requires parallel simulation of all possible states of the chain. To avoid simulating all the trajectories, several strategies have been implemented. But they are related to the structure of the chain and require a monotonicity property, or a construction of a bounding chain that exploits the lattice structure of the state space or the local character of the transitions.In the field of communications networks, attention is paid to the performance of queueing networks, that can be distinguished into two groups: the networks that have a product form stationary distribution which is easy to compute. Random generation can be used for the others. Perfect sampling algorithms can be used for open queueing networks, thanks to the lattice structure of their state space. Unfortunately, that is not the case for closed queueing networks, due to the size of the state space which is exponential in the number of queues and a global constraint (a constant number of customers). The main contribution of this thesis is a new data structure called a diagram. It is inspired by dynamic programming and allows a new technique of construction of bounding processes. The first part of the manuscript is devoted to the implementation of the Propp and Wilson algorithm for closed queueing networks. The representation of a set of states by a diagram and the transition operation for the bounding process has a polynomial complexity in the number of queues and customers. This technique is extended to closed multi-class networks and to networks with synchronizations. Specification of sets of objects that can be represented by a diagram and generic algorithms that use this data structure are proposed in this manuscript. The Boltzmann method is another unbiased sampling technique. It is based on analytical combinatorics and produces uniform samples from objects that belong to the same combinatorial class. It is used in the second part of this thesis in order to sample the stationary distribution of closed networks with product form and for the generation of multisets of fixed cardinality. Diagrams are used again in this context. Finally, the third part presents the software produced during this thesis, implementing diagrams and perfect simulation of closed queueing networks.

This Master's thesis concerns the description of the systems used for the support of the administrative processes in legal offices. It focuses on finding the processes in offices, analyzes the possibilities for their simplification and automation. The great emphasis is placed especially on possibilities of automatic acquisition of information from public databases. Furthermore, the thesis describes and compares already existing solutions that are commonly available on the market. In another part of this thesis is being solved proposal of system itself and choice of suitable technologies for its practical implementation. The main goal of this paper is to implement the system according to generated proposal and its testing on real data.

Manually diagnosing recurrent faults in software systems can be an inefficient use of time for engineers. Manual diagnosis of faults is commonly performed by inspecting system logs during the failure time. The DevOps engineers in Pipedrive, a SaaS business offering a sales CRM platform, have developed a simple regular-expression-based service for automatically classifying failed deployments. However, such a solution is not scalable, and a more sophisticated solution isrequired. In this thesis, log mining was used to automatically diagnose Pipedrive's failed deployments based on the deployment logs. Multiple log parsing and machine learning algorithms were compared based on the resulting log mining pipeline's F1 score. A proof of concept log mining pipeline was created that consisted of log parsing with the Drain algorithm, transforming the log files into event count vectors and finally training a random forest machine learning model to classify the deployment logs. The pipeline gave an F1 score of 0.75 when classifying testing data and a lower score of 0.65 when classifying the evaluation dataset.
