In this application, the Euler equations have been discretized by means of the Galerkin Finite Element Method (GFEM) using the CBS (Characteristic Based Split) scheme. pySolver, a multiplatform object-oriented software, built around the set of open source tools Python, Blender and Visit, besides C language, exhibits a proper graphical user interface and a framework specially developed to deal with data pre-processing and capable of geometrical modeling of either two or three-dimensional problems. The author has also implemented a scheme for the mesh refinement, by adapting the open-source softwares Triangle and TetGen, obtaining local and dynamic mesh refinement until reaching a determined tolerance in the results. That refinement scheme has contributed to considerable application robustness. In order to compare the software, some test cases composed of supersonic and hypersonic flows over di erent geometrical configuration bodies, mostly encountered in the aerospace and aeronautic industry data, have been simulated. The results compared very well with experimental data from the literature and, when possible, with other numerical results also obtained in the literature.

The prove presented is an application of the theorem of Brown representability in derived categories for compact complex, ie, given Z be a compact and indecomposable complex, we show that there is a Auslander-Reiten triangle X->U->Y->v->Z->w->TX in K-b(^) which is equivalent to D(^), where ^ is a finite-dimensional k-algebra over an algebraically closed field. Furthermore, we have that a triangle Auslander-Reiten wihch start with the projective resolution of a indecomposable and non-injective module T-¹pM->alfa->Y->Beta->(pDM)*->y->pM induces an Auslander-Reiten sequence(SAR) 0->M->alfa¹->Cok¹ (Y)-> beta¹->Tr DM->0. How Mod(^) and D(^) are Krull-Schmidt, and classes of indecomposable objects and generators of irreducible morphisms of these categories occur in the SAR's and TAR's, respectively, these results provide us with a skillful tool to know the structures Mod(^) and D(^) of k-algebras. Moreover, we present examples using the representation theory of quivers of an algebra of paths. / Neste trabalho, apresentamos uma prova da existência de triângulos de Auslander-Reiten(TAR) para objetos compactos em categorias trianguladas compactamente geradas. A prova apresentada é uma aplicação do Teorema da Representabilidade de Brown em categorias derivadas para complexos compactos, ou seja, dado Z um complexo compacto e indecomponíveL mostramos que existe um triângulo X->U->Y->v->Z->w->TX de Auslander-Reiten em K-b(^) que é equivalente à Db(^), onde ^ é uma k-álgebra de dimensão finita sobre um corpo algébricamente fechado. Além disso, temos que um triângulo de Auslander-Reiten que começa com a resolução projetiva de um módulo indecomponível não-injetivo T-¹pM->alfa->Y->Beta->(pDM)*->y->pM induz uma sequência de Auslander-Reiten(SAR) 0->M->alfa¹->Cok¹ (Y)-> beta¹->Tr DM->0. Como MOd(^) e D(^) são Krull-Remak-Schmidt, e as classes de objetos inde- componíveis e os geradores de morfismos irredutíveis destas categorias ocorrem nas SAR's e nos TAR's, respectivamente, estes resultados nos fornecem uma hábil ferramenta para conhecer as estruturas de Mod(^) e D(^) de k-álgebras. Além disso, apresentamos exemplos utilizando a teoria de representação de quivers de uma álgebra de caminhos.

Este trabalho tem por objetivo investigar produções argumentativopersuasivas e efeitos de sentido depreensíveis de textos impressos veiculados nas revistas do mundo dos negócios EXAME, Época NEGÓCIOS e ISTOÉ Dinheiro. Em especial, interessa-nos o pensamento de Mestre Aristóteles: é pelo discurso que persuadimos, sempre que demonstramos a verdade ou o que parece ser a verdade. Considera-se a tríade aristotélica éthos, páthos, lógos. Modernamente, esses componentes retóricos são representados no ato comunicativo pela relação entre as três instâncias: o orador (enunciador), o auditório (enunciatário) e o discurso. A argumentação é ferramenta imprescindível da Retórica e mantém presença, em escalas distintas, em todos os textos/discursos. O processo argumentativo não é fundado no vazio: há sempre um propósito e o envolvimento de mais de um indivíduo. Argumenta-se para alcançar consenso sobre divergências em determinado ponto de vista; para confirmar e reforçar crenças e valores radicados em um indivíduo ou em um grupo específico; para, enfim, por meio de discurso dado como eficaz, obter a adesão do auditório: convencer ou persuadir o outro. A constatação de produções argumentativo-persuasivas recorrentes nos textos das revistas remete a certa imagem que o orador (enunciador) faz do seu auditório/enunciatário-leitor: o páthos, reconhecido como imagem da disposição, estado de espírito da instância de recepção, concretizada em sujeito discursivo do universo de sentido da esfera social de negócios empresariais. Com os conceitos da Nova Retórica, firma-se fortemente o prestígio do auditório particular no processo argumentativo-persuasivo. Ao considerar as produções discursivas voltadas a esse auditório específico, a pesquisa adentra os estudos das paixões que modalizam sujeitos sociais, inseridos nessa esfera de sentido delimitada: a corporativoempresarial. / This work aims at showing argumentative-persuasive techniques observed in texts of the printed versions of EXAME, Época NEGÓCIOS and ISTOÉ Dinheiro, magazines from the corporate business discursive sphere. In special, we are interested in the thought of Aristotle: it is through discourse that we persuade, when we show the truth or what appears to be the truth. The Aristotelian triad éthos, páthos, lógos, which in modern times is represented by the relation of the instances of the orator (enunciator), the audience (enunciatee-reader), and the discourse is examined at length. Argumentation, an indispensable tool of Rhetoric, can be found in different levels in all texts/discourses. The argumentative process is not grounded in the void: there is always a purpose and involvement of more than one individual. The argumentation process intends to reach a consensus about some divergent points of view; to confirm and strengthen beliefs and values deeply rooted in an individual or a group; to hold, in short, the audience´s adherence through a discourse considered effective: convincing or persuading other people. The findings of recurrent argumentative-persuasive productions in the texts of magazines result in an apprehension by the orator/enunciator of certain audience/enunciatee-reader´s image: the páthos, recognized as the image of disposition, the inclination of the instance reception, materialized in the subject of discourse of the social sphere of corporate business. With the New Rhetoric concepts, the prestige of a particular audience takes deep roots in the argumentative-persuasive process. When considering the discursive productions directed to a specific audience, this work engages the study of the passions that modalize social subjects belonging to this restricted meaning sphere of meaning: corporate business.

A Dissertação versa sobre as obras para a construção da Estação Sé do Metrô de São Paulo realizadas no início da década de 1970. O foco principal é o resultado dessa intervenção na praça produzida por aquelas obras. Antes, havia duas praças com importante história na cidade, a Praça da Sé, com a Catedral em seu ponto mais elevado, e a Praça Clóvis Beviláqua, com o Tribunal de Justiça como destaque, com um quarteirão todo edificado entre elas, que foi demolido para a construção da estação e da praça que surgiu. Dentre essas edificações demolidas, duas expressam muita simbologia e assumem caráter importante para o desenvolvimento do trabalho, o Palacete Santa Helena e o Edifício Mendes Caldeira. Aquele simbolizava o pensamento da esquerda e de uma época áurea da cidade; esse representou a força do autoritarismo, já que foi a primeira implosão realizada / This dissertation runs upon the works for the construction of the Sé Subway Station in Sao Paulo, conducted in the early 1970s. The main focus is the result of this intervention in the square produced by those works. Before, there were two squares with important history in the city, the Sé Square with the Cathedral at its highest point, and the Clovis Beviláqua Square, with the Court of Justice as a highlight, with a whole city block built between them, which was demolished to the construction of the station and the square that arose. Among those demolished buildings, two express much symbolism and play an important role in the development of this study: the Santa Helena Palace and the Mendes Caldeira Building. The first one symbolized the left wing thinking and a golden age of the city, the other one represented the strength of authoritarianism, since it was the first implosion held in the country at that time.

Familjer med små barn som inte tål mjölk upplever att de behöver praktisk hjälp med mat och måltider. Syftet var att undersöka om, och i så fall hur, recept kan möta de behov som familjerna upplever att de har. Totalt 15 recept togs fram. På två workshoppar fick 11 familjer testa recepten genom att provlaga och smaka de tillagade måltiderna. Under workshopparna intervjuades föräldrarna om vad de tyckte om recepten och om vilka behov de har. Resultatet visar att recept kan vara en praktisk hjälp för familjer med mjölkallergi – om recepten tar hänsyn till de behov kring mat som familjerna har. Familjernas behov är motstridiga, men det går att sammanföra dem i recept. För att kunna kombinera deras behov av bekvämlighet och ansvar för näringsriktig mat måste det vara snabb och enkel mat som samtidigt utgår ifrån små barns näringsbehov utan att innehålla mjölk. Även identitet, som är kopplat till smak, är viktigt. God mat är synonymt med bekanta smaker som är vanliga i många barnfamiljer. / Families with small children who are allergic to milk experience that they require practical advice on food and meals. The purpose of this study was to investigate if, and if so how, recipes can meet the needs regarding food and meals that these families feel that they have. Total 15 recipes were developed. These were tested by 11 families by cooking and tasting the meals at two workshops. During both workshops the parents were interviewed to find out their opinions on the recipes as well as their needs. The results indicate that recipes may be a useful remedy for families with milk allergy, given that the recipes consider the families’ very needs as regarding to food. The needs of the families’ are contradictory, however they can be summed up into recipes. In order to combine the families’ need for ease and responsibility for nutritious food, the food must be quick and simple but still emanate from the nutritional requirements for small children with milk allergy. Likewise identity related to taste is important. Good food is synonymous with well-known tastes for families with children.

The thesis is about the arrangement of the last known claim values into the run-off triangle. This diagram is used in non-life insurance, mainly in methods for calculating technical claims reserves. Individual methods will be described in detail and consecutively applied on real data. The real data are a set of data with long tail. We are differentiating between easier deterministic and stochastic methods, which are more demanding for calculation. The results will be compared by basic statistical parameter of the analyzed data and at the end the best method will be chosen for the data.

In den letzten Jahren häuften sich spektakuläre Bilanzskandale, was zu einer „Krise der Überwachungssysteme“ geführt hat. Vor diesem Hintergrund beschäftigt sich die Studie mit der Untersuchung und der Würdigung des Managerverhaltens im Prüfungsverhältnis aus Interner Revision, Aufsichts- bzw. Verwaltungsrat und Abschlussprüfer im Vergleich deutscher und kamerunsicher Aktiengesellschaften. In der Studie sollen die wesentlichen Elemente ans Licht gebracht werden, welche die Interaktionsmuster und die unterschiedlichen Verhaltensstrategien charakterisieren, die von den Akteuren mittels der sich ihnen bietenden Freiräume genutzt werden können. Mit Hilfe der für jedes Land spezifischen rechtlichen Rahmenbedingungen werden die Interaktionen zwischen diesen Akteuren anhand eines Prüfungsdreiecks dargestellt bzw. aufgezeigt. Die Analyse des Zusammenspiels der Akteure bietet auch die Möglichkeit, die formelle und die informelle Macht der Akteure des Prüfungsprozesses Anhang ausgewählter Corporate-Governance-Theorien zu extrahieren. Auf diesen Charakteristika aufbauend wurde eine den einzelnen Aktiengesellschaft entsprechende Management-Typologie erstellt. Anschließendes Ziel der Studie ist die Entwicklung eines einheitlichen Corporate Governance Modells sowie die Formulierung von Empfehlungen zur Verbesserung der Überwachungsstruktur der Aktiengesellschaft.:Erster Teil: Gegenstand und theoretischer Rahmen der Untersuchung 1.

The study thus aims to bring to light the essential elements that characterize the nature of the interactions and the different behavioral strategies that the actors can use through the freedom afforded to them. With the help of the legal frameworks specific to each country, the interactions between these actors are presented through an examination triangle. Based on the exchanges, it is also possible to extract the formal and informal power of the actors in the audit process Appendix of selected corporate governance theories. Based on these characteristics, we introduce a management typology corresponding to the individual public limited companies. Instead, the aim is to develop a unified corporate governance model and recommendations for improving the supervisory structure of the public limited company.:Erster Teil: Gegenstand und theoretischer Rahmen der Untersuchung 1.

The content of the diploma thesis was an architectural study of a sacral building in Brno - Líšeň. The subject of the study was the elaboration of an ideological design of a sacral complex, which consisted of a church and a parish. The main operator of the whole complex will be the Salesian community, whose background is in close proximity to the area. The basic idea of the design was to design a spiritual place, which in its form conveys clear information about the use of the object and at the same time supports the development of ideas of the Salesian community. It is a structure that conveys the mission itself, not by one element, but by a set of several elements that together create a story, vision, mission. The ideological solution in this case thus becomes an equilateral triangle, which symbolizes the Father, the Son and the Holy Spirit. With its dominant vertical direction facing the sky, the object symbolically points to the spiritual path and self-realization. The given area is solved as a complex, the elements of which complement each other and thus create a harmonious whole. The design creates a space for both liturgical celebrations in the interior and exterior, which is used by the outdoor presbytery, which is complemented by residential stairs. These elements are intended to encourage residents to meet and establish friendly relations.
