A clareira da casa-pátio

Silva, Enilton Braga da January 2017 (has links)
Esta dissertação parte da indagação sobre o arquétipo residencial arquitetônico da casa-pátio, que se configura como um vazio na habitação, um espaço confinado, protegido e oculto. Este pátio interno, fechado, com suas sutis mas ricas características, conferem a ele uma ambiência única, com uma peculiar atmosfera. Essa indagação originou-se a partir da vivência do autor, como estagiário de arquitetura, em uma casa na cidade de Porto Alegre, construída na década de 1970, de autoria do arquiteto Elyseu Victor Mascarello (1935- 2008), formado em 1958, na Universidade Federal do Rio Grande do Sul, onde foi aluno do primeiro corpo docente da instituição. A investigação consolida a busca do autor pela compreensão sobre o que estava em jogo na clareira da residência, quem eram os atuantes, e se haveria uma forma de mimetizar aquela condição em novos projetos ou outras situações. A identificação do pátio interno como uma clareira na casa e sua aproximação metafórica com o conceito heideggeriano da clareira do ser (Lichtung) conduz a pesquisa à investigação sobre a fenomenologia de acordo com a visão de Heidegger, relacionando a clareira filosófica, existencial, à clareira física, doméstica. Nestas condições, a clareira da casa-pátio Mascarello torna-se o cerne central da pesquisa, na busca pelas nuances presentes que a configuram, que a potencializam. A clareira de Heidegger é definida e aproximada à casa sagrada, existencial. No âmbito doméstico, outros exemplos de tipologias de clareiras em casas-pátio são desvelados, analisando-se suas potencialidades de clareiras. Este trabalho busca, portanto, trazer uma nova luz à casa com pátio interno, sob a égide da ancestralidade conceitual da casa, analisando o microcosmos criado, a presença da natureza e do cosmos em diferentes tipologias de casas-pátio. / This dissertation arose out of the inquiry concerning to the architectonic residential archetype of the courtyard house, which is configured by an empty area in the habitation, a confined, protected and occult space. This enclosed inner courtyard, with its subtle yet rich features, gives it a unique ambience with a peculiar atmosphere. This investigation was originated from the author’s experience, as an architectural intern, in a house located in Porto Alegre, built in the 1970s, by the architect Elyseu Victor Mascarello (1935-2008). Mascarello graduated in 1958, from the Federal University of Rio Grande do Sul, where he had been a student of the first academic teachers of the institution. The investigation consolidates the author's search for an understanding of what was at stake in the clearing of the residence, what were the active elements, and whether there would be a way of miming that condition into new projects or into other situations. The identification of the internal courtyard as a clearing in the house and its metaphorical relation, with the Heideggerian concept of the clearing of being (Lichtung), leads the research to the investigation of phenomenology, according to Heidegger's view, relating the existential philosophical clearing to the physical domestic clearing. Under these conditions, the clearing of Mascarello’s courtyard house becomes the central focus of the research, aiming to find the existing nuances, which configures and enhances the clearing. Heidegger's clearing is defined and related to the sacred, existential house. Within the domestic scope, other examples of clearing typologies in courtyard houses are unveiled, analyzing their potential for clearings. This work thus aims to shed a new light on the house with internal courtyard, under the aegis of the conceptual ancestry of the house, analyzing the created microcosm, the presence of nature and of the cosmos in different courtyard house typologies.

Análise teórica e experimental sobre incandescência em espécimes de madeira /

Rabelo, Elaine Reis de Carvalho. January 2003 (has links)
Resumo: Este trabalho trata da combustão sem chama, denominada incandescência, em espécimes de madeira. O estágio de incandescência é muito comum em queimadas florestais, ocorrendo após o período de chamas, quando a biomassa de tamanho maior permanece fumegando por até vários dias. Este material, em estado de incandescência, é foco permanente de emissão de gases tóxicos bem como de re-ignição de biomassa não queimada. Os objetivos principais do trabalho são: verificar experimentalmente os parâmetros que favorecem o início e a continuidade do processo de incandescência e quantificar as concentrações de CO, CO2, O2 e HC durante a queima. Também serão determinadas temperaturas, em diferentes pontos dos corpos de prova, a velocidade da frente de incandescência e, finalmente, a taxa de queima. Os ensaios foram feitos em um forno de 1,80 m de comprimento por 0,60 m de diâmetro, conectado a um controlador de temperatura, com vazões de ar de combustão previamente estabelecidas. Além da vazão de ar, outros parâmetros também variaram, como a temperatura interna do forno, a espécie da madeira, o volume e a umidade da amostra. Para otimizar a execução dos testes foi aplicada a técnica de "Projeto de Experimentos". Os ensaios de laboratório foram comparados com os resultados obtidos em uma queimada realizada no interior da floresta Amazônica, no norte do estado de Mato Grosso. / Abstract: This work investigates non flaming combustion in biomass logs. The process is called smouldering combustion. The occurrence of smouldering is very common in forest fires, where the large sized biomass remains fuming for several days. The material in the state of is a source of toxic gases and of ignition for unburned biomass. The main goals of the work are experimentally check the parameters that favor initiation and permanence of the smouldering process and measure CO, CO2, O2 and HC concentrations during the burning. The velocity of the smouldering front was determined by thermocouples placed in different points of the biomass sample. The average burning rate was also determined. The tests were performed in a furnace of 1.80 m length by 0.60 m diameter. A temperature controller was used to set the desired furnace temperature. The mass flow rate of air was controlled by valves and measured with rotameters. Tests were conducted for different biomass species and sample volumes and moisture contents. To optimize the number of tests the technique "Project of Experiments" was applied. Results of the laboratory tests agreed well with those obtained in the Amazon forest, in the north of the state of Mato Grosso, Brazil. / Orientador: João Andrade de Carvalho Junior / Coorientador: Carlos Alberto Gurgel Veras / Banca: Luiz Roberto Carrocci / Banca: Mauricio Araujo Zanardi / Doutor

Simulationsgestützte Kapazitätsbedarfsabschätzung in der operativen Produktionsplanung und -steuerung

Lange, Frederick 10 October 2014 (has links) (PDF)
Die Produktionsplanung in kommerziellen Enterprise Ressource Planning Systemen und Produktionsplanungs- und -steuerungssystemen erfolgt unter unzureichender Berücksichtigung von beschränkten Kapazitäten. Dies führt oft zu unzulässigen Plänen, welche nicht selten zu einer Verfehlung der termingerechten Bedarfsdeckung führen. Durch den Einsatz sogenannter Clearing Functions (CF) können die nicht linearen Abhängigkeiten zwischen der Arbeitslast eines Produktionssystems und der zu erwartenden Ausbringungsmenge beschrieben werden. Eine solche CF kann empirisch durch den Einsatz von Simulation ermittelt werden und zu einer verbesserten Kapazitätsabschätzung in der operativen Produktionsplanung und -steuerung beitragen.

Právní úprava obchodování s OTC deriváty / Regulation of Trading in OTC Derivates

Matys, Tadeáš January 2017 (has links)
This thesis addresses the current, ever-developing framework of rules governing trading in the most widespread financial instrument - OTC derivatives. The main objective of the thesis is to analyse the current state of the regulation of trading in OTC derivatives within the EU - namely, the EMIR Regulation. Subsequently, it examines whether the legal framework has been set up properly and effectively, and explores what steps should be taken in the near future in order to improve it. Given that the subject of this thesis is much more of an economic than a legal nature, its first part introduces OTC derivatives as a concept, and the specifics of trading in them. The second part examines the status of OTC derivatives within the financial market over time, starting from their modern-day beginnings in the 1990s, through their role in the global financial crisis of 2007 and 2008, to the current issues related to them. The main part of the thesis is devoted to the EMIR Regulation, its scope of application, and in particular the three main obligations which EMIR introduces in relation to OTC derivatives. These comprise, firstly, the obligation to perform a central clearing through central counterparties; secondly, the obligation to observe specific risk mitigation techniques for OTC derivative contracts...
