Повний текст джерелаIn his recent theory of grounds, Prawitz develops his semantic investigations towards an analysis of the epistemic power which valid inferences are endowed with to compel one to accept the conclusion, provided one is justified in holding the premises true. A ground is what one is in possession of when one is justified in asserting a sentence. Grounds are built by performing operations that allow to pass from an evidence state to another evidence state. An inferential act consists of an application of an operation on grounds. The theory of grounds allows for undoubted advancements with respect to Prawitz's previous proof-theoretic semantics. In particular, it provides a definition of the notion of valid inference which makes the epistemic power of proofs depend on the epistemic power of the valid inferences of which proofs are built up. But the two semantics also share a problem; in both of them, valid inferences and proofs might be such that it is impossible, for agents who perform them, to recognize that they justify their conclusions. We develop the formal framework of Prawitz's proposal, by introducing a "universe" of grounds and operations on grounds, as well as some formal languages and systems of grounds. Then, we focus on two issues: the completeness of intuitionistic logic, and the aforementioned recognizability problem

Повний текст джерелаQuestion:
"Does the market possess perfect information as the efficient market hypothesis says?"
"Is there any significant relationship between the abnormal stock return on the ex – day and the dividend?" Purpose: The purpose of this study is to enlighten and find understanding about stock return versus dividend on the ex – day and try to figure out if abnormal returns occur on the portfolio during dividends.
Methodology:
The study was based in a quantitative nature and was derived with an event study and a hypothesis testing. The authors investigated the thirty most traded shares on the Stockholm stock exchange during a period of five years (2005 – 2009). They were analyzed during a total of nine days; the estimation window was set to sixty days. Theory: Leading theories in this field of study have been picked to enlighten and analysis the questions of the study. Theories used: Efficient market hypothesis, agent theory and the events of dividends.
Empiricism / Results:
The authors made an event study and hypothesis tested the information. From the data they could see a small abnormal return on every day except the day after the ex – day. However, they could not prove a significant relationship between the stocks return and the dividend.
Conclusion / Discussion:
The efficient market hypothesis was strengthened in the conclusion where all new information is reflected in the stock price because the null hypothesis was accepted in all nine cases. The authors also concluded that although they have a differentiated result compared to other studies, it could be a result of the recession. Another conclusion was that the relationship between shareholders and the management has been improved because of a better spread of information.

Повний текст джерелаIn this paper we study Graph Theory, addressing various definitions and interesting theorems. We present the Four Color Theorem, since the origin of the problem with Francis Guthrie. We analyze the proof of the theorem presented by Alfred Bray Kempe, and its refutation by Percy John Heawood counter-example. We also analyze the Percy John Heawood demonstration of the Five Color Theorem. Finally, we present the first valid proof of the Four Colors Theorem, with its peculiarity of having been done with the aid of a computer. We conclude with an analysis of the beneficial that the knowledge of Graph Theory can render students of Basic Education, and how a teacher can work this topic in the classroom, including addressing the problem of map coloring.

In this dissertation project, I examine the ways in which a grassroots environmental organization, the Upper French Broad Defense Association (UFBDA), was able to contribute knowledge and voice concerns regarding a Tennessee Valley Authority (TVA) proposal between 1961 and 1972. The TVA proposal included a plan for comprehensive water resource development in western North Carolina which would have required in the implementation of 14 dams, flooding of more than 18,000 fertile agricultural acres and displacing 600 families from their ancestral homes. In order to complete this dissertation project, I explored two archival collections pertaining to the UFBDA. Based on my findings in the archives, I provide new understandings of how grassroots environmentalism works, particularly in terms of how environmentalists use language in order to participate in decisions about the environment. More specifically, this dissertation documents how members of the UFBDA were able to describe the western North Carolina landscape as a commons and not a wilderness, work together across counties to create new opportunities to share their concerns over the TVA project, and establish their own credibility as knowledgeable citizens about their local environment. By highlighting specific components of the UFBDA's work, this dissertation provides examples that can be used by future grassroots environmental organization facing similar challenges regarding environmental controversies.

Neste trabalho relembramos as fórmulas simples encontradas para as amplitudes MHV de gluons e gravitons nos contextos de super-Yang-Mills com supersimetria N = 4 e de supergravidade com supersimetria N = 8. A seguir, relembramos a prescrição proposta por Berkovits e Maldacena [5] que facilita o cálculo dessas amplitudes para gluons no contexto de supercordas abertas, e que reproduz os resultados corretos para 4 e 5 gluons além de se reduzir aos resultados de sYM no limite 'alfa linha' = 0, conforme veri?cado em [5] e [22].

Повний текст джерелаIn this thesis we investigate the quantum integrability of the Alday-Arutyunov-Frolov model (AAF) by diagonalization of the Hamiltonian of the AAF transformed model. The AAF transformed model is obtained from original model after fields redefinition whose purpose is to transform the Dirac brackets in the standard canonical structure between two fermions. For the diagonalization of the Hamiltonian of the transformed model we use the method developed for the Landau-Lifshitz model. This method requires regularization of the singular product of operators at the same point as well as construction of the selfadjoint extensions. We show that the wave function and the states of the transformed AAF exhibit discontinuities. We also investigated the equivalence of the matrices S of the two formulations of the AAF model through direct calculation of the S-matrix in both theories. We also consider the equivalence theorem applied to AAF model. To shows that the S matrix is invariant under field redefinitions.

Повний текст джерелаO estouro da bolha imobiliária nos EUA que culminou na crise financeira de 2008-09 reacendeu o interesse no estudo das vulnerabilidades que resultam de elevados níveis de alavancagem financeira. Para estudar a relação entre a alavancagem e os preços dos ativos, esta dissertação apresenta um modelo que replica uma economia com dois períodos, dois ativos diferentes, sendo um mais arriscado que o outro, onde dois estados da natureza podem ocorrer. As crenças heterogéneas dos agentes que pertencem a esta economia resultam em diferentes expectativas acerca do retorno esperado do ativo com risco. Esta heterogeneidade dita que apenas os agentes mais otimistas participam do mercado de ativos de risco. Assim, quando o crédito é introduzido nesta economia essa taxa de participação diminui em função do aumento do preço do ativo com risco. Do modelo apresentado retira-se que a taxa de retorno do ativo com risco depende positivamente do índice de alavancagem do agente (ou rácio Financiamento-Garantia). Esta dissertação realiza ainda uma análise de regressão multivariada, através de dados trimestrais do mercado de habitação que constam na base de dados do BCE, e descobre que a taxa de retorno da habitação na área euro reage negativamente ao aumento da alavancagem financeira das famílias observado no trimestre em análise, mas tem uma reação positiva e mais forte ao nível de alavancagem observado no trimestre anterior. Estes resultados sugerem que a taxa de retorno do mercado imobiliário pode demorar a responder a alterações nos requisitos dos financiamentos hipotecários.
The housing bubble burst following the emergence of leverage-fuelled property booms observed in the US culminated in the financial crisis of 2008-09 did regain the interest on the vulnerabilities that result from higher levels of leverage. To capture the relation between leverage and its influence on asset bubbles, this paper presents a model to replicate an economy with two periods, two different assets, with one riskier than the other, where two states of nature can occur. The heterogeneous beliefs of agents belonging to this economy result in different assignments on the expected return of the risky asset which in turn dictates that only the more optimistic agents participate in the risky asset market. When agents have access to credit to purchase the risky asset, this participation rate diminishes as a result of the increasing price of the risky asset. One can also derive from this model that the rate of return of the risky asset depends positively on the agent?s leverage ratio (or Loan-to-Value ratio). By using quarterly housing data from the European Central Bank Data Warehouse, this paper does a multivariate regression analysis to find the housing return rate in the Euro area reacts negatively to increasing households? leverage observed in the current quarter, but has a higher positive reaction from the leverage level observed in the previous quarter. The results suggest the rate of return of the housing market may show some delay to reply to looser margin requirements.

Este trabalho apresenta uma aplicação real da teoria das restrições (theory of constraints - TOC) no gerenciamento de uma cadeia de suprimentos, demonstrando como esta metodologia pode trazer importantes melhorias no desempenho global do sistema de abastecimento. Tais melhorias são obtidas por intermédio da redução dos níveis gerais de estoques e, ao mesmo tempo, pela minimização das oportunidades de vendas perdidas, ocasionadas devido à indisponibilidade de produtos nos pontos de consumo (clientes finais). Os principais conceitos da TOC, tais como, os processos de raciocínio, a programação tambor-pulmão-corda (TPC) e o TPC-simplificado, foram adaptados do ambiente de manufatura para a utilização prática numa cadeia de suprimentos, permitindo a emersão dos principais dilemas que afetam o desempenho do processo de distribuição. A compreensão deste contexto propicia um melhor balanceamento entre os ganhos globais da cadeia e os ganhos pontuais de cada parceiro. Salienta-se, ainda, que o processo de estoque gerenciado pelo fornecedor (vendor-managed inventory - VMI) e os recursos do business-to-business (B2B) são fortalecidos quando utilizados junto aos preceitos da TOC, robustecendo o desempenho do sistema e diminuindo, ainda mais, os níveis de estoques, através da minimização do efeito chicote (bullwhip effect). Uma aplicação prática é apresentada para evidenciar a viabilidade e os benefícios da proposta, em que o ERP CIS (Customer Integrated System) utiliza, em seu módulo logístico, o VMI integrado à TOC e a um B2B na internet. O modelo opera como um sistema de planejamento e programação avançados (advanced planning and scheduling – APS), realizando todo o compartilhamento de informações entre os ERPs, desde os fornecedores até os clientes.
This research presents a real application of the theory of constraints (TOC) to the management of a supply chain, in order to demonstrate how this methodology can introduce important improvements in the entire supply system performance. These improvements are gained by decreasing the general inventory levels and, at the same time, reducing losses of sales opportunities due to the lack of goods at sales points (end-customers). The main concepts of TOC, as the thinking process, the drum-bufferrope schedule (DBR) and the simplified-DBR, were adapted from the manufacturing environment to a practical use in a supply chain, providing a better perception of the abstruse dilemmas that constrains the performance of the distribution system. The comprehension of this context enables a better balance between the global gains of the supply chain and each local earnings of each partner. Moreover, the vendor-managed inventory (VMI) and the business-to-business (B2B) are strengthened when related with the TOC conception, making a robust system performance and decreasing, even more, the inventory levels, by minimizing the bullwhip effect. A practical application is presented to evidence the feasibility and the benefits of this proposal, where the CIS ERP (Customer Integrated System) relates its logistic module the integrated VMI to TOC and B2B to the internet. This model operates as an advanced planning and scheduling system (APS), accomplishing all data sharing between the ERPs from the suppliers to the customers.

Waiting lines are boldly present in our society following us since the beginnings of civilization. Sometimes they occur in a traditional way with a well-seen aspect and thus look like similar to the model we already have in mind, but also there are times in which waiting lines occur in di erent formats becoming unperceivable to the common observer not yet introduced to the Queuing Theory. The present study aims in demonstrating the applicability of Mathematics. Statistics and the Queuing Theory to real tasks such as the waiting line of a bank cashier in the City of Jataí-Goiás. In this regard we present a short history of the Queuing Theory embracing its advent, the rst task to be dealt with, the de nitions and the adopted terminology looking forward to subsidize a theoretical base in an introductory level. As our object of observation is a waiting line of a bank cashier we additionally present a short history of the National Financial System in which comprehends every bank, and also the municipal law that rules the maximum waiting time in a line. After the choice of a bank agency in the City of Jataí-Goiás we succeeded to get access to the detailing tape of the cashiers under managers authorization. The tape has all the data about daily transactions. The time of analysis refers to the month of November 2014. After appropriate organization and data cataloging, they were processed according to the Queuing Theory illustrating its applicability. Results allowed us to work a few mathematical concepts, specially the idea of average. However, more detailed results and analysis were not dealt with in this work due to its complexity but will be considered in future studies that might take the present work as a starting point.
As las tem presença marcante em nossa sociedade e nos acompanham desde o início da civilização. Algumas vezes manifestam-se de forma tradicional e apresentam caráter bastante visual assemelhando-se assim ao modelo que temos em nossas mentes, mas às vezes manifestam-se de formas variadas e tornam-se imperceptíveis ao olhar não familiarizado com a Teoria das Filas. O presente texto teve como propósito mostrar a aplicabilidade da matemática, estatística e Teoria das Filas a problemas reais tal como a la de guichê de caixa de uma agência bancária da cidade de Jataí-Go. Para isso apresentamos um breve histórico da Teoria das Filas, contemplando o seu surgimento, o primeiro problema estudado, as de nições e os termos empregados visando subsidiar um embasamento teórico em nível básico. Por ter se pautado na análise da la do caixa de uma agência bancária complementarmente apresentamos um breve histórico do Sistema Financeiro Nacional - SFN no qual todos os bancos encontram-se inseridos e a lei municipal que normatiza o tempo máximo de espera em la. Após escolhido uma agência bancária na cidade de Jataí-Go conseguimos com a autorização do gerente a ta detalhe dos caixas, a qual nos apresenta os dados referentes a movimentação diária. O período de análise refere-se ao mês de novembro do ano de 2014. Após a devida organização e catalogação os dados foram tratados sob o olhar da Teoria das Filas ilustrando a aplicabilidade desta teoria. Os resultados possibilitaram trabalhar alguns conceitos básicos da matemática, em especí co o conceito de média. Contudo, resultados e análises mais elaboradas deixaram de ser tratadas no presente texto, devido a sua complexidade, mas serão analisados em textos futuros que poderão ter este como ponto de partida.

Повний текст джерелаENGLISH ABSTRACT: The following thesis aims to contribute to the field of teaching German as a foreign language. It investigates the evolutionary history of Suggestopaedia, an alternative teaching method which originated during the late 1970s. The Bulgarian psychiatrist, Dr. Georgi Lozanov, discovered that relaxation and a stress-free environment promote both accelerated learning and memory retention. Further research proves that the combined elements and techniques of this method play a significant role to positively manipulate brain activity as well as individual perceptions, which could eventually result in the development of the personality. The author of this study analyses both the contributions and shortcomings of Suggestopaedia, reporting from personal experience gathered while teaching at a university in South Africa, and subsequently suggests an altered version of the suggestopaedic teaching ways. Various foreign language teaching methodologies are examined and evaluated while the main focus remains on Suggestopaedia and its principle of holistic learning. By exploiting the eclectic aspects of the suggestopaedic teaching method, this thesis investigates to what extent selected elements of different conventional methods can be integrated into Suggestopaedic teaching. Thereby the author ultimately proposes a holistic, enriched and modernized variant of Lozanovs Suggestopaedia for the teaching of German at schools in South Africa, by demonstrating practical examples executed at a private school.
AFRIKAANSE OPSOMMING: Hierdie tesis poog om ʼn bydrae te lewer tot die gebied in die onderrig van Duits as ʼn vreemdetaal. Dit ondersoek die evolusionêre geskiedenis van Suggestopedie wat as „n onderrigmetode in die laat 1970‟s ontstaan het. Die Bulgaarse psigiater, dr. Georgi Lozanov, het bevind dat „n ontspanne en stresvrye omgewing beide versnelde leer en geheue retensie bevorder. Verdere navorsing toon dat die gekombineerde elemente en tegnieke van hierdie metode „n betekenisvolle rol speel om brein-aktiwiteit positief te manipuleer en individuele persepsies positief te beïnvloed, wat ten slotte ʼn persoonlikheidsontwikkeling tot gevolg kan hê. Die skrywer van hierdie studie analiseer sowel die bydrae asook die tekortkominge van Suggestopedie aan die hand van persoonlike ervaring wat versamel is tydens onderrig aan „n Suid-Afrikaanse universiteit. Hieruit word dan „n gewysigde weergawe van suggestopediese onderrig voorgestel. Verskeie vreemdetaal-onderrigmetodes word ondersoek en geassesseer, terwyl die fokus steeds op Suggestopedie en die beginsel van holistiese leer bly. Deur gebruik te maak van die eklektiese aspek van die suggestopediese leermetode, ondersoek die skrywer tot watter mate geselekteerde elemente van verskillende konvensionele metodes geintegreer kan word met Suggestopedie. Met bogenoemde navorsing inaggeneem, stel die skrywer gevolglik „n holistiese, verrykte en gemoderniseerde weergawe van Lozanov se Suggestopedie voor, aan die hand van praktiese voorbeelde wat by „n privaatskool toegepas is.

Повний текст джерелаThe main aim of this work is to present an association of elastic plate theory and plastic analysis, to beamless slabs (flat slabs and flat plates) analysis. Rectangular panels uniformly loaded were considered. Elastic plate theory is used to predimensioning, determining the relation between positive bending moments and permiting to fix the ultimate negative moments of resistance. Plastic analysis is made by Yield Line Theory, that is used to obtain ultimate moments of resistance, which are used in dimensioning. Two complete examples are also presented, to compare results of elastic plate theory with those relative to proposed proceeding. Elastic calculus is made by Equivalent Frame Method. There was not significant difference between results obtained with the two processes in the considered examples. New researches are suggested in order to perfect proposed proceeding.

Resumo: Este trabalho apresenta uma aplicação real da teoria das restrições (theory of constraints - TOC) no gerenciamento de uma cadeia de suprimentos, demonstrando como esta metodologia pode trazer importantes melhorias no desempenho global do sistema de abastecimento. Tais melhorias são obtidas por intermédio da redução dos níveis gerais de estoques e, ao mesmo tempo, pela minimização das oportunidades de vendas perdidas, ocasionadas devido à indisponibilidade de produtos nos pontos de consumo (clientes finais). Os principais conceitos da TOC, tais como, os processos de raciocínio, a programação tambor-pulmão-corda (TPC) e o TPC-simplificado, foram adaptados do ambiente de manufatura para a utilização prática numa cadeia de suprimentos, permitindo a emersão dos principais dilemas que afetam o desempenho do processo de distribuição. A compreensão deste contexto propicia um melhor balanceamento entre os ganhos globais da cadeia e os ganhos pontuais de cada parceiro. Salienta-se, ainda, que o processo de estoque gerenciado pelo fornecedor (vendor-managed inventory - VMI) e os recursos do business-to-business (B2B) são fortalecidos quando utilizados junto aos preceitos da TOC, robustecendo o desempenho do sistema e diminuindo, ainda mais, os níveis de estoques, através da minimização do efeito chicote (bullwhip effect). Uma aplicação prática é apresentada para evidenciar a viabilidade e os benefícios da proposta, em que o ERP CIS (Customer Integrated System) utiliza, em seu módulo logístico, o VMI integrado à TOC e a um B2B na internet. O modelo opera como um sistema de planejamento e programação avançados (advanced planning and scheduling - APS), realizando todo o compartilhamento de informações entre os ERPs, desde os fornecedores até os clientes.
Abstract: This research presents a real application of the theory of constraints (TOC) to the management of a supply chain, in order to demonstrate how this methodology can introduce important improvements in the entire supply system performance. These improvements are gained by decreasing the general inventory levels and, at the same time, reducing losses of sales opportunities due to the lack of goods at sales points (end-customers). The main concepts of TOC, as the thinking process, the drum-bufferrope schedule (DBR) and the simplified-DBR, were adapted from the manufacturing environment to a practical use in a supply chain, providing a better perception of the abstruse dilemmas that constrains the performance of the distribution system. The comprehension of this context enables a better balance between the global gains of the supply chain and each local earnings of each partner. Moreover, the vendor-managed inventory (VMI) and the business-to-business (B2B) are strengthened when related with the TOC conception, making a robust system performance and decreasing, even more, the inventory levels, by minimizing the bullwhip effect. A practical application is presented to evidence the feasibility and the benefits of this proposal, where the CIS ERP (Customer Integrated System) relates its logistic module the integrated VMI to TOC and B2B to the internet. This model operates as an advanced planning and scheduling system (APS), accomplishing all data sharing between the ERPs from the suppliers to the customers.

Resumo: Vários Sistemas de Atendimento Emergenciais (SAE's) sofrem com as variações diárias da demanda e da disponibilidade das ambulâncias. Nesses sistemas pode haver flutuação do desempenho ao longo do dia devido, por exemplo, a mudança no número de servidores e nas taxas de chegada, levando à necessidade de considerar explicitamente tais variações em uma extensão ao modelo hipercubo ainda não explorada na literatura. Como ocorre em alguns SAE's, as ambulâncias melhor equipadas são reservadas para o atendimento exclusivo de chamados com risco de vida. Dessa maneira, a política de despacho pode ser diferenciada com a finalidade de reservar totalmente o atendimento de alguns servidores para certas gravidades de ocorrências. Além disso, somam-se à natureza aleatória desses sistemas, como por exemplo, as incertezas da disponibilidade das ambulâncias, a chegada de um novo chamado e sua localização. Nesse contexto, os objetivos do presente estudo são: (i) estender o modelo hipercubo de filas para reserva total de capacidade, dependendo do tipo do chamado; (ii) estender o modelo hipercubo de filas para torná-lo mais eficiente computacionalmente, sem haver perda de precisão durante a modelagem e resolução; e (iii) propor uma abordagem baseada no modelo hipercubo não-estacionário para organização do trabalho das ambulâncias em qualquer momento do dia. Para verificar a viabilidade e a aplicabilidade dessas abordagens, é realizado um estudo de caso no SAMU da cidade de Bauru (SAMU-Bauru) que,... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Many Emergency Service Systems face daily variations on demand and ambulance availability. These systems may suffer, for example, performance fluctuations throughout the day, changes on the number of servers and on arrival rates, leading to the need to explicitly consider such variations in a hypercube model extension not yet explored in the literature. As occurs in some SAMU's, which reserve their best equipped ambulances to exclusively serve life-threating requests. Therefore, the dispatch policy can be differentiated in order to completely reserve the service of some ambulances to more severe requests. These problems add up to the random nature of these systems with uncertainties upon ambulance availability or the arrival of a new request and its location. Thus, this study aims to: (i) extend the hypercube queueing model to be able to capture the complete capacity reservation of advanced ambulances, depending on the request classification; (ii) extend the hypercube model in order to make it more computationally efficient, without losing any information during modeling and resolution. (iii) propose an approach based on nonstationary hypercube queueing model to organize the operation of ambulances at any time of the day. To verify the feasibility of these approaches, a case study is carried out on the SAMU from Bauru city (SAMU-Bauru), which, in addition to the advanced ambulance reservation for life-threating requests, is affected by daily variations in demand and ambulance availability. In addition to the original configuration of SAMU-Bauru, studied on a two-step approach, we studied a total of four alternative scenarios that exploited important matters as: the impact of average demand increase on the congestion peak; mitigation of this impact by including a new ambulance; changing the schedule of daily breaks; and the...

Este trabalho procurou identificar como estudantes do Ensino Médio se apropriam de conceitos e elaboram determinados modelos inseridos em Cinética Química, especificamente o modelo cinético de colisão de partículas numa reação (Teoria das Colisões). Esta análise e as reflexõe que a seguiram foram baseadas principalmente nos estudos realizados por Piaget (1975, 1975b, 1977), Piaget & Inhelder (1975, 1977), Jun (2000) e Fischbein (1975). Utilizamos como documentos as transcrições das entrevistas (pré e pós-testes) realizadas individualmente com cada aluno. Inicialmente os estudantes foram entrevistados (pré-testes) com o intuito de identificar a familiaridade com a noção de evento probabilístico ou aleatório. Numa segunda etapa (pós-testes) esse conhecimento (ou a ausência parcial/total dele) foi posto à prova numa tentativa de estabelecer relações com um conteúdo específico da Química (Teoria das Colisões). Os resultados obtidos apontam para grandes discrepâncias entre o modelo cinético de colisões elaborado pelos estudantes e o cientificamente aceito.
The purpose of this work is to contribute for Science teaching making analysis and reflections on the way high school students appropriate the concepts and models related to Chemical Kinetics, mainly particles collisions' kinetics model in chemical reaction (Collision Theory Model). This investigation was based on Piaget and Inhelder' studies (1975), and also on Piaget (1975, 1977), Jun (2000), and Fischbein (1975) works, which have studied the connection between the young students and the probabilistic thinking. The analysis of the document evidences had the aim to evaluate if the students would be able to achieve generalization and develop concepts about Probability Theory. In the second part these concepts or its partial/total lacks were linked with chemical kinetics in attempt to establish relationships between correct explanation of collision kinetic model and the students' failure models. The obtained result points to great misconceptions related to the correct and scientific model and the student's.

Повний текст джерелаNesta tese analisamos a localização de campo de matéria em bramas duplas. Estudamos a localização de férmions não-massivos em paredes de domnio (3-brana) imersa no espaço de 4+1 dimensões em cenários Randall-Sundrum (espaço warped), e Rubakov-Shaposhnikov (espaço plano), respectivamente. Abordamos a localização do campo fermiônico, acoplando os férmions com uma função de campo escalar, cuja solução tipo kink simples é deformada a uma solução tipo kink duplo. No contexto de nosso estudo, este tipo de configuração kink duplo permite ilustrar o fenômeno da separação das branas. Construímos novos modelos não-lineares em teoria de campos que forneçam configurações do tipo kink duplo. Estes modelos são construídos a partir da deformação do modo-zero associado `a equação de estabilidade de outros modelos bem estabelecidos. Por sua vez, estes modelos são aplicáveis na descrição de fenômenos críticos e em cenários de mundos-brana. Além disso, temos conhecimento de que não ´e possível a localiza¸c˜ao de campo de gauge por meio unicamente da curvatura (warped). Propomos um mecanismo que leve à localização do modo-zero do campo de gauge abeliano em branas espessas por meio de uma função suave e contínua que torna a ação normalizável. Esta função suave funcionaria como uma função dielétrica. Neste mesmo contexto, aplicamos este mecanismo para a localização do modo-zero do campo de Kalb-Ramond em branas espessas
In this thesis we analyze the localization of matter field in double branes. We study the localization of massless fermions in domain wall (3-branes) immerse in a space 4+1 dimensions in Randall-Sundrum (warped space), and Rubakov-Shaposhnikov (flat space) scenarios, respectively. We approach the fermions localization, coupling the fermions to a scalar field functional, whose kink-like solutions are deformed to double kink solutions. In the context of our study, this double kink (two-kink) allows to illustrate the brane splitting phenomenon. We construct new non-linear models in field theory which provides double kink configurations. These models are constructed from the deformation of the zero mode associated to the stability equations of well-established models. In turn, these models are applicable in the description of critical phenomena and brane-worlds scenarios. Moreover, we know that it is not possible to achieve gauge fields localization on brane by means of only the warped curvature. We propose a mechanism that leads to the localization of zero mode of Abelian gauge field in thick branes by means of a smooth and continuous function which turns out the action normalizable. This smooth function would work as a dielectric function. In this same context we apply this mechanism for the localization of zero mode of Kalb-Ramond field in thick branes

Повний текст джерелаThis research aims to analyze the period of philosophical thought of B. Russell and L. Wittgenstein between the years of 1905 and 1914 describing the development of the philosophy of logical atomism present in the Tractatus logico-philosophicus of Wittgenstein. For this aim, will be observed the criticism of Wittgenstein to the theory of judgment developed by Russell and which would be grounds for the theory of knowledge that Russell was elaborating. We recognize, from the criticism, that Russell had a strong influence of the empiricism of his day, which made his epistemology fragile. This weakness is evidenced by Wittgenstein that, by criticizing some key points of the theory of judgment, made Russell take the fragility of his own arguments and inevitably stopped with the production of his second philosophical project after Principia mathematica, as currently entitled Theory of knowledge and usually known as \"the 1913 manuscript.\" Wittgenstein, on the other hand, produces in the same period his first and only book published in life, the Tractatus logico-philosophicus, which opens and proposes a new understanding of the logic of language through a radicalization of Russell\'s theory of descriptions. This radicalization is done through the postulation of logically simple names that designate simple objects. The postulation is justified by the picture theory drafted in the Tractatus, which maintains the necessary link between logic and world and contributes that the sense of any thought be shown without the requirement of explanations linked to empiricism.

Resumo: A constante evolução do poder computacional aliada ao baixo custo de aquisição, faz com que os computadores sejam indispensáveis para construção de modelos de simulação. Atualmente, a simulação por computador é usada nas mais diversificadas áreas, como previsão meteorológica, dimensionamento de centrais telefônicas, e estudos aerodinâmicos. A presente dissertação valida e comprova a eficácia de modelos de simulação construídos no software Mathematica 10 por meio do software Arena 14.50. Para isso, foi construído um modelo que, sem focar nas condições reais do sistema, simula de forma hipotética (levando em conta apenas o número de canais de comunicação disponíveis e o tempo de médio duração das chamadas) o tráfego oferecido por chamadas de áudio e vídeo em uma ERB (Estação Rádio-Base) CDMA (Code Division Multiple Access) ou GSM (Global System for Mobile) que nesse trabalho, é representada por um sistema de fila. Diversos cenários de tráfego foram analisados utilizando diferentes parâmetros como a quantidade de chamadas ingressantes, tempo de duração da chamada e o número de canais disponíveis. Os resultados finais comprovaram que os modelos de simulação criados no Mathematica 10 são equivalentes aos modelos de simulação construídos no Arena 14.50
Abstract: The constant evolution of power of computers together with their low cost of aquisition, make them indispensable in building of simulation models. Nowadays, computer simulation is used in a variety of areas such weather forecasting, sizing of telephone stations and in aerodynamic studies. This essay validate and proves the effectiveness of these simulation models built on The Mathematica 10 software with the Arena 14.50. In order to do that, a model was built and without focusing on System s real condition, it simulates in a hypothetical way (considering only the number of communication channels available and average length of the calls) The traffic offered by audio and vídeo calls through a RBS (Radio Base Station) CDMA (Code Division Multiple Access) or GSM (Global System for Mobile) which herein is shown through a queue system. Various traffic scenarios were analyzed using different setups, like quantity of incoming calls, length of calls and number of available channels. The final results confirmed that the simulation models built on Mathematica 10 are equivalents to The simulation models built on Arena 14.50
