My thesis consists of two parts. First part is theoretical in which I´m introducing meanings of reference and determinant as described by eminent authors, followed by description of the main uses of definite and indefinete articles and I´m finishing the first part by introducing the current Sentence Segmentation. The second part of the Thesis is practical and here I´m working on quantitative analysis of determination and its translation itno Czech. I´m analyzing a tale called La tortuga gigante from the book Cuentos de la Selva written by Horacio Quiroga and its further Czech translation by Ada Vesela. Determinants are my main focus, articles in particular and their translation into Czech.

In this dissertation we study non-negative self-adjoint Laplace type operators acting on smooth sections of a vector bundle. First, we assume base manifolds are compact, boundaryless, and Riemannian. We start from the Fourier integral operator representation of half-wave operators, continue with spectral zeta functions, heat and resolvent trace asymptotic expansions, and end with the quantitative Wodzicki residue method. In particular, all of the asymptotic coefficients of the microlocalized spectral counting function can be explicitly given and clearly interpreted. With the auxiliary pseudo-differential operators ranging all smooth endomorphisms of the given bundle, we obtain certain asymptotic estimates about the integral kernel of heat operators. As applications, we study spectral asymptotics of Dirac type operators such as characterizing those for which the second coefficient vanishes. Next, we assume vector bundles are trivial and base manifolds are Euclidean domains, and study non-negative self-adjoint extensions of the Laplace operator which acts component-wise on compactly supported smooth functions. Using finite propagation speed estimates for wave equations and explicit Fourier Tauberian theorems obtained by Yuri Safarov, we establish the principle of not feeling the boundary estimates for the heat kernel of these operators. In particular, the implied constants are independent of self-adjoint extensions. As a by-product, we affirmatively answer a question about upper estimate for the Neumann heat kernel. Finally, we study some specific values of the spectral zeta function of two-dimensional Dirichlet Laplacians such as spectral determinant and Casimir energy. For numerical purposes we substantially improve the short-time Dirichlet heat trace asymptotics for polygons. This could be used to measure the spectral determinant and Casimir energy of polygons whenever the first several hundred or one thousand Dirichlet eigenvalues are known with high precision by other means.

The aim of this work is to analyse functions of French articles as a part of the text in comparison with the means of Czech language. The theoretical part defines determinants as a word class in French language as well as its function in conjunction with nominal group, ways of linking in the text and structure of the text. All of this is based on the works of French and Czech authors concerned in the question of articles. The comparative part was done on the text accessible in both languages. The texts were analysed in the same way and then they studied all the questions from the theoretical part i.e. functions of the article in the text and its language means in Czech. The results were put into two tables. First table presents Czech equivalents of nominal group. Second table presents Czech equivalents of the way of linking in the text.

Tem como objetivo mostrar a utilização do Método da Eliminação de Gauss-Jordan para a resolução de sistemas de equações lineares, cálculo de matrizes inversas e cálculo de determinantes. A motivação para a escolha desse tema é que, cada vez mais, o estudo das matrizes, dos determinantes e, consequentemente, dos sistemas de equações lineares vem sendo deixado de lado no Ensino Médio. Inicialmente, é feito um pequeno apanhado sobre o que são matrizes equivalentes e operações elementares, além de se falar sobre cofator de um elemento de uma matriz e sobre matriz adjunta, necessária para o cálculo da inversa utilizando-se determinantes. Apresenta-se um pouco da história de Gauss e de Jordan e, logo em seguida, o método propriamente dito. Também é visto o que acontece com o método quando as matrizes não são invertíveis, os sistemas são possíveis e indeterminados ou os sistemas são impossíveis. Quanto aos determinantes, são apresentadas suas propriedades e mostrada a eficácia do método para determinantes de ordem n 3 e, além disso, é mostrada a aplicação dos determinantes no cálculo de inversas e na resolução de sistemas de equações pela Regra de Cramer. Finalmente, são apresentadas sugestões de exercícios com uma breve resolução. / This work is oriented to teachers and students in the high school. It aims to show the usage of Gauss-Jordan’s Elimination Method to solve systems of linear equations, calculation of inverse matrices and determinants. The motivation behind the selection of this topic is that, more and more, the study of matrices, determinants, and consequently, systems of linear equations has been ignored in the high school. Firstly, an abridgement is done on what equivalent matrices and elementary operations are. Secondly, it explains about the cofactor of an element of a matrix and about adjoint matrices, needed for the calculation of the inverse matrix using determinants. A little introduction of Gauss and Jordan’s histories is made, and then, the method itself. It is also shown what happens with the method when the matrices are not invertible, the systems are possible but undetermined, or, the systems are not possible. Concerning determinants, their properties are presented and the method’s efficacy for determinants of order n 3 is shown and furthermore, it is shown the application of the determinants in the calculation of inverse matrices and resolutions of systems using Cramer’s Rule. Finally, some suggestions for exercises are presented with brief resolutions.

Objetivo Caracterizar a ocorrência de dengue na cidade de Rio Brando, estado do Acre, no período de 2000 a 2007, no tempo, no espaço e segundo infestação pelo Aedes aegypti e vari- áveis demográficas, socioeconômicas, ambientais e climáticas. Métodos Foi realizada uma descrição da incidência de dengue (CI) e da infestação predial pelo Aedes aegypti (IIP) no período de 2000 a 2007 a partir de dados secundários. Descreveu-se a incidência da dengue em relação ao sexo, faixa etária e escolaridade. O Coeficiente de Incidência e o Índice de In- festação Predial foram testados para aferição de correlações com variáveis climáticas, demo- gráficas, ambientais e socioeconômicas. Foi aplicada a técnica de geoprocessamento com o uso da estatística espacial de Moran Global e Local (LISA) para avaliar a autocorrelação es- pacial dos coeficientes de incidência de dengue entre as localidades urbanas da cidade. Resul- tados - A epidemiologia da dengue na cidade é caracterizada por elevada incidência e intensa infestação predial pelo Aedes aegypti. Não existe diferença na incidência de dengue entre ho- mens e mulheres e a faixa etária mais acometida compreende jovens e adultos de 15 a 49 anos e escolares que não concluíram o ensino médio. A distribuição da doença mostra um padrão sazonal com elevação da incidência nos períodos chuvosos e regressão nos períodos secos. O aumento de casos de dengue e da infestação predial mostrou associação significante (p<0,05) com bairros populosos, onde existe muitos imóveis e alta infestação predial. O aumento das ocorrências se mostrou significante com áreas com baixo índice de abastecimento de água pela rede pública. O Índice de Qualidade de Vida (IQV) não apresentou correlação significa- tiva com a ocorrência de dengue, entretanto, a infestação predial foi mais elevada nos bairros com melhor IQV. A estatística de Moran Global e Local (LISA) mostrou fraca dependência espacial (p<0,05) da incidência de dengue entre bairros da cidade. Conclusão - A análise epi- demiológica da dengue na cidade permitiu visualizar fatores que estão relacionados à trans- missão de dengue e na proliferação do Aedes aegypti que podem ser avaliados na formulação de estratégias mais eficazes para alcançar o melhor controle da doença. O uso da análise espa- cial evidenciou que a distribuição da incidência de dengue entre os bairros da cidade ocorre de maneira aleatória / Objective - Characterize the ocurring of dengue in the city of Rio Branco, Acre, during the period 2000 to 2007, in time and space, and according to the infestation of Aedes Aegypti and the demographic, social-economical, environmental and climatical variables. Methods - a description of dengue incidence (CI) and the house infestation by Aedes aegypti (HI) was made in the period of 2000 to 2007 from secondary data. The distribution of cases was described according to gender, age and education. The Incidence Coefficient of incidence and the House Index Infestation were tested to measure their correlations with demographic, environmental and socioeconomic climatic variables. The geoprocessing technique was applied with the use of Global and Local Moran (LISA) spatial statistics to evaluate spatial autocorrelation of incidence of dengue among the urban localities in the city. Results - The epidemiology of dengue in the city is characterized by high incidence and severe infestation of Aedes aegypti. Theres no difference between the incidence of dengue on men and women and the most affected age group comprises young adults from the age of 15 to 49 years old and students who have not completed high school. The distribution of the disease shows a seasonal pattern with increased incidence in rainy periods and regression in dry periods. The increase of dengue cases and the building infestation showed significant association (p <0.05) with the populated districts, where there are many buildings and high building infestation. The increase in occurrence was found significant in areas with low public water supply. The Quality of Life Index (QLI) showed no significant correlation with the occurrence of dengue, however, the infestation rate was higher in districts with better QLI. Global and Local Moran (LISA) statistics showed weak spatial dependence (p <0.05) of the incidence of dengue among neighborhoods. Conclusion - The epidemiological analysis of dengue in the city allowed the visualization of the factors that are related to the transmission of dengue and the proliferation of Aedes aegypti that can be assessed in the formulation of more effective strategies to achieve better control of the disease. The use of the spatial analysis revealed the randomness of dengue incidence distribution among the neighborhoods of the city

A existência de especificidade temporal na produção do confinamento de bovinos, que limita o período de negociação e busca por preços mais atrativos, corrobora com a necessidade do uso de mecanismos de hedge. Este pode ser feito pelo confinador com o uso da BM&F Bovespa, via contratos futuros e de opções, ou diretamente com os frigoríficos, por meio de contratos a termo. O objetivo desta dissertação é identificar fatores determinantes para a utilização de hedge (contratos futuros, de opções e termo) por confinadores. Foram realizadas pesquisas com confinadores participantes de eventos realizados em Ribeirão Preto-SP, em 2012 e 2013, e por telefone em 2014. Para a análise dos dados foram utilizadas estatísticas descritivas. Em seguida, com uso do Teste Exato de Fisher, foi analisada a associação das características dos confinamentos e pecuaristas ao uso do hedge. Com o intuito de identificar os determinantes para o uso de ferramentas de gestão de preços, foram elaborados modelos de regressão logística. Os resultados indicaram que o tamanho do confinamento, a escolaridade do gestor, o controle acurado de custos, o confinamento exclusivo, a utilização de hedge para os grãos, uso anterior de ferramentas e a parceria com frigoríficos têm relação com a utilização de uma ou mais formas de gestão de risco de preços do boi gordo. / The existence of temporal specificity in the production of feedlot cattle, which limits the period of negotiation and search for more attractive prices, confirms the necessity of using hedging mechanisms by feedlot cattle producers. The hedging can be done via BM&F Bovespa, through futures and options, or directly with slaughterhouses, through forward contracts. The aim of this study is identify determinants for using hedge (futures contracts, options contracts and forward contracts) by feedlot cattle producers. Surveys were applied to participants of events in Ribeirão Preto-SP, in 2012 and 2013, and via phone in 2014. Descriptive statistics of data were obtained and the determinants for using hedge were investigated using hypothesis tests. The relations between the producer\'s and feedlot\'s characteristics with hedging use were tested by Fisher Exact Test. In order to identify the determinants for the use of hedge, logistic regression models were implemented. The results have indicated that the size of the confinement, the manager\'s educational level, the high cost control, the feedlot as the only activity, the use of hedging for grains, the prior use of these tools and the partnership with slaughterhouses are related to the use of one or more ways to manage price risk of cattle.

The Division of Computer Engineering at Linköping's university is currently researching the possibility to create a highly parallel DSP platform, that can keep up with the computational needs of upcoming standards for various applications, at low cost and low power consumption. The architecture is called ePUMA and it combines a general RISC DSP master processor with eight SIMD co-processors on a single chip. The master processor will act as the main processor for general tasks and execution control, while the co-processors will accelerate computing intensive and parallel DSP kernels.This thesis investigates the performance potential of the co-processors by implementing matrix algebra kernels for QR decomposition, LU decomposition, matrix determinant and matrix inverse, that run on a single co-processor. The kernels will then be evaluated to find possible problems with the co-processors' microarchitecture and suggest solutions to the problems that might exist. The evaluation shows that the performance potential is very good, but a few problems have been identified, that causes significant overhead in the kernels. Pipeline mismatches, that occurs due to different pipeline lengths for different instructions, causes pipeline hazards and the current solution to this, doesn't allow effective use of the pipeline. In some cases, the single port memories will cause bottlenecks, but the thesis suggests that the situation could be greatly improved by using buffered memory write-back. Also, the lack of register forwarding makes kernels with many data dependencies run unnecessarily slow.

Introduction : Une faible situation sociale est associée à un risque accru de mortalité et morbidité. Plusieurs facteurs ont été étudiés en lien avec cette association, mais un mécanisme proposé par Tarlov (1996), soit la dissonance entre les attentes et la réalité, n’a pas été investigué. De plus, peu d’études ont examiné en profondeur les facteurs sociaux et psychosociaux influençant la santé avec la participation des personnes vivant la pauvreté et l’exclusion sociale. Objectifs et méthodologie : Cette étude vise à identifier et à décrire les facteurs nuisant à la santé d’adultes ayant un faible revenu, les stratégies et actions de ces personnes en lien avec ces facteurs et les effets de la participation pour ces personnes. Cette étude a utilisé une approche de recherche participative et une méthode de présentation de problèmes selon la pédagogie de Freire. Les participants et participantes étaient huit adultes ayant un faible revenu, fréquentant un organisme communautaire en milieu urbain. Ces personnes ont participé à huit rencontres de groupe, comprenant des activités comme la présentation d’images ou d’histoires représentatives et le jeu de rôle. Ces personnes ont aussi participé à l’analyse thématique des données, incluant cinq rencontres de groupe. Résultats et conclusions : Cette étude identifie un nouveau facteur psychosocial, soit la dissonance entre la situation actuelle perçue et l’idéal de situation conçu tôt dans la vie. Cette dissonance génère un profond mal-être et suit la perte ou la non atteinte de l’idéal de situation. Les autres facteurs identifiés soutiennent ceux d’études précédentes et sont groupés sous les thèmes du manque d’amour et de soutien tôt dans la vie et de la situation actuelle comme prison sociale. Cette étude identifie aussi un effet important de la participation, peu rapporté dans les études participatives, soit les découvertes personnelles ou une meilleure compréhension de soi dans le monde. L’approche de recherche participative combinée à la méthode de présentation de problèmes selon la pédagogie de Freire permet les découvertes personnelles et peut être un moyen d’accompagner les personnes vivant un profond mal-être. Les actions, interventions et politiques devraient permettre aux personnes de réaliser leur idéal de situation et de répondre aux besoins d’amour et de soutien des enfants. / Abstract: Introduction: Poor social circumstances, including low social status, are associated with a higher risk of mortality and morbidity. Many factors have been studied in relation to this association, but a mechanism advanced by Tarlov (1996) concerning dissonance between expectations and reality has not been investigated. Moreover, few studies have examined in depth social and psychosocial factors influencing health, with the participation of people living in poverty and social exclusion. objectives and methodology: This study aims to identify and describe the factors harming the health of low-income adults; the strategies and actions used by low-income adults, which are linked to these factors; and the effects on the participants of participation in the study. This study used a participatory research approach and a problem-posing method based on Freire’s pedagogy. The participants were eight low-income adults using food bank services provided by a community organization in an urban setting. They participated in eight group meetings, which included activities such as presentation of representative stories or images and role-playing. They also participated in the data analysis, during five additional meetings. Results and conclusions: This study identifies a new psychosocial factor, namely, the dissonance between current perceived circumstances and one’s ideal of circumstances conceived early in life. This dissonance generates profound malaise and follows a loss or a failure to achieve the ideal of circumstances. Other factors identified support those from previous studies and are grouped into two themes: lack of love and support from an early age, and current circumstances as a trap. This study also identifies an important and under-reported outcome of participation, which is the experience of personal discoveries or a better understanding of the self in the world. A participatory research approach combined with a problem-posing method based on Freire’s pedagogy enables personal discoveries and might be a means for accompanying people with profound malaise. Actions, interventions, and policies should enable people to achieve their ideal of circumstances and to respond to children’s needs for love and support.

Ces dernières années, les fusions et acquisitions transfrontalières réalisées par les entreprises chinoises en Europe et en Amérique du Nord se sont développées et ont attiré l’attention des chercheurs. Cependant, il existe peu de recherches se concentrant sur leurs motivations, leur performance et leurs déterminants. Ainsi, l’objectif de cette thèse est d’analyser les opérations annoncées ou réalisées en Europe et en Amérique du Nord entre 2002 et 2012, afin de (1) comprendre les motivations des entreprises en croissance, (2) de déterminer si ces opérations créent de la valeur pour les actionnaires et (3) d’identifier les déterminants de la création/destruction de valeur. Pour ce faire, nous avons utilisé trois méthodes : (1) l’analyse des déclarations d’acquisitions faites par les entreprises chinoises, (2) le calcul de rendements anormaux (AAR, ACAR, CAR) via plusieurs études d’évènements, (3) l’élaboration d’un modèle d’identification des déterminants de la création/destruction de valeur. Les opérations analysées ont été réalisées par des entreprises cotées aux bourses de Shanghai, Shenzhen et Hongkong. Des données supplémentaires ont été tirées de la base de données « Zephyr ». Au total, 93 opérations ont été analysées. Les résultats confirment les résultats antérieurement identifiés pour les acquéreurs occidentaux, étendant ainsi les théories des F&A aux opérateurs chinois. Malgré la différence de structure de propriété (contrôle par l’Etat), les FMN chinoises ont un niveau de performance comparable à leurs homologues occidentaux privés lorsqu’elles réalisent des opérations de F&A. / In recent years, the cross-border mergers and acquisitions by Chinese companies in Europe and North America are developing and have attracted the attention of researchers. However, there is few research focusing on their motivations, their performance and their determinants. Thus, the objective of this thesis is to analyze the transactions announced or completed in Europe and North America between 2002 and 2012, (1) to understand the motivations of growing companies, (2) to know whether these operations create value for shareholders and (3) to identify the determinants of the creation / destruction of value.To do this, we used three methods: (1) analysis of acquisitions statements made by Chinese companies, (2) the calculation of abnormal returns (AAR ACAR CAR) via several events studies (3) development of a model to identify the determinants of the creation / destruction of value. The operations were made by Chinese listed companies in Shanghai, Shenzhen and Hong Kong stock exchanges. Additional data were obtained from the database "Zephyr." A total 93 operations were analyzed. The results confirm the previously identified results for western acquirers. Despite the difference in ownership structure (state control), Chinese MNCs have a level of performance comparable to their private western counterparts when they carry out operations of M & A.
