Devido ao seu crescimento acelerado o município de Curitiba deverá, em breve, ter seu espaço subterrâneo ocupado com maior intensidade. Este processo deve ser devidamente planejado, levando-se em conta as propriedades geotécnicas do subsolo. Assim, buscou-se desenvolver e aplicar um método de caracterização geotécnica do meio urbano para fins de planejamento do espaço subterrâneo. O trabalho consistiu no mapeamento tridimensional das principais unidades geotécnicas e na sua caracterização em termos de adequação para obras subterrâneas. Para tanto, inicialmente, reuniu-se dados geotécnicos existentes (sondagens, poços, mapas topográficos), e levantou-se pontos em campo. A partir do mapa topográfico gerou-se imagens artificiais do terreno, que foram reunidas aos demais dados em um sistema de informações geográficas (SIG). Este processo permitiu a elaboração de um mapa geológico simplificado. Os dados armazenados no sistema (SPT, profundidades das unidades geológicas, entre outros) passaram por uma filtragem, sendo exportados para a realização de análises geoestatísticas, interpolações e geração de cartas de isovalores. Grades regulares com valores interpolados foram então inseridas no SIG, constituindo-se um modelo geotécnico digital tridimensional que permite a navegação virtual entre unidades geotécnicas. Através de classificação geomecânica determinou-se as condições de suporte e estabilidade para possíveis túneis em rochas do município. No caso dos solos realizaram-se análises limite considerando informações de campo e ensaios SPT. Integrando- e, em um único documento, cartas de profundidade das unidades geotécnicas, o mapa geológico simplificado e informações construtivas para túneis, gerou-se um mapa orientativo para a construção de obras subterrâneas no município de Curitiba. Este mapa pode ser diretamente aplicado no planejamento de ocupação do subterrâneo. / Due to its fast population increase, the city of Curitiba will soon have to use its underground space. However, underground space use should be previously planned, taking geotechnical information into consideration. Therefore, the present research is intended to develop and apply an urban geotechnical characterisation method for underground space planning. The work consisted of a 3D mapping of main geotechnical units and determination of their suitability for underground constructions. At first, existing geotechnical data, such as borehole logs, well logs and topographic maps, have been collected and stored. Field studies were carried out subsequently. Digital terrain models have been obtained from topographic maps, and integrated with the other data in a geographical information system (GIS). This process allowed for the production of a simplified geological map. The stored data have been filtered and exported for the development of geostatistical analysis, interpolations and contour maps. Interpolated grids were then reinserted in the GIS software, where a 3D digital geotechnical model has been produced, permitting virtual navigation through soil layers. Tunnel stability and support design evaluations have been performed by means of rock mass classifications. For soil tunnel stability and support assessments, field studies and N-SPT correlations have been used along with limit analysis. A decision support geotechnical map for underground constructions has been obtained by representing, in a single document: the simplified geological map, geotechnical unit depth contour charts, tunnel stability and support analysis results. This decision support map may be directly applied for underground space planning activities.

Desde a criação, na década de 90, dos veículos populares, cuja característica principal é a utilização de motores até 1.0 litro de capacidade volumétrica, tem influenciado fortemente o mercado de veículos brasileiro, tendo mais 50% de participação no market share desde o inicio de suas vendas. Diante do atual cenário da Indústria Automotiva Brasileira, este trabalho tem como objetivo estudar a possibilidade de estender o período de garantia em veículos populares para 36 meses como vantagem competitiva de mercado. O modelo proposto, com o suporte de conceitos de confiabilidade e de falhas de produtos, consiste em utilizar os dados de falhas de campo para estimar os gastos em garantia após 36 meses de exposição no campo, o que permite analisar as suas vantagens e desvantagens para a tomada de decisão por parte da empresa. Este estudo recomenda também um plano de validação técnica para a extensão de garantia que consiste em submeter veículos provenientes do campo de provas da empresa a uma quilometragem elevada para verificação da durabilidade e confiabilidade de seus componentes dentro do período de 36 meses de exposição no campo. O plano de implementação da extensão da garantia para veículos populares recomenda a introdução de dois anos de garantia no mercado de forma que o produto seja monitorado quanto ao seu comportamento de falhas e possíveis reclamações dos clientes, gerando informações para que a empresa decida quanto à manutenção do período de garantia para três anos. Finalmente a extensão do período de garantia para veículos populares é possível, desde que todos os níveis da organização estejam comprometidos e que seja feito um planejamento prévio utilizando-se de todos os dados e recursos disponíveis para a tomada de decisão. / Since their creation in the beginning of 90 decade, the popular vehicles, which main characteristic is the use of engines up to 1.0 liter of volumetric capacity, have strongly influenced the Brazilian market of vehicles, having more than 50% of participation in the market share since the beginning of their sales. Based on the current scenario of the Brazilian Automotive Industry, this work has the objective of suggesting a model to evaluate the warranty extension for popular vehicles to 36 months as a market competitive advantage. The study, supported by reliability and product failures theoretical concepts, consists of using the field failure data to estimate the warranty cost in 36 months exposure in the field, which allows analyzing its advantages and disadvantages for company decision making. This study also recommends a technical validation plan for warranty extension that consists of submitting vehicles from the company proving ground to high mileages to verify their parts durability and reliability in 36 months of field exposure. The warranty extension implementation plan recommends the implementation of two years warranty in the market, monitoring the failures and customers complaints during this period to generate information for company for decision making to implement the three years warranty. Finally, the warranty extension for popular vehicles is possible since all levels of the organization are committed and a previous plan must be done using all the information and resources available for company decision making.

Interest in more accurate assignment of overhead costs to establish credible product/service cost profiles has assumed substantial prominence in much of the recent debates on management accounting practices. While the promotion of new cost management systems and in particular Activity Based Costing (ABC) has promised to address many of the perceived shortcomings of more traditional and long established techniques, the lack of its implementation success raises some concern as to the validity and value of these new system designs. A major purpose of this thesis is the development of a mathematical model that is capable of computing overhead allocations on the basis of organisational specific dimensions other than DLH.While almost all data bases suffer from data entry and omission errors, the information content contained in the data bases often forms the basis for management decisions without first confirming the accuracy of the data base content. The model has been successfully applied and tested to detect internal consistency and data element detail accuracy. Future research may test the applicability of the model with more diverse data bases to confirm its generalisability as an investigative as well as predictive model. / Doctor of Philosophy (PhD)

The project was aimed at describing the mixing phenomena relevant for both safety analysis, particularly in steam line break and boron dilution scenarios, and mixing phenomena of interest for economical operation and the structural integrity. Measurement data from a set of mixing experiments, gained by using advanced measurement techniques with enhanced resolution in time and space help to improve the basic understanding of turbulent mixing and to provide data for Computational Fluid Dynamics (CFD) code validation. Slug mixing tests simulating the start-up of the first main circulation pump are performed with two 1:5 scaled facilities: The Rossendorf coolant mixing model ROCOM and the VATTENFALL test facility, modelling a German Konvoi type and a Westinghouse type three-loop PWR, respectively. Additional data on slug mixing in a VVER-1000 type reactor gained at a 1:5 scaled metal mock-up at EDO Gidropress are provided. Experimental results on mixing of fluids with density differences obtained at ROCOM and the FORTUM PTS test facility are made available. Concerning mixing phenomena of interest for operational issues and thermal fatigue, flow distribution data available from commissioning tests (Sizewell-B for PWRs, Loviisa and Paks for VVERs) are used together with the data from the ROCOM facility as a basis for the flow distribution studies. The test matrix on flow distribution and steady state mixing performed at ROCOM comprises experiments with various combinations of running pumps and various mass flow rates in the working loops. Computational fluid dynamics calculations are accomplished for selected experiments with two different CFD codes (CFX-5, FLUENT). Best practice guidelines (BPG) are applied in all CFD work when choosing computational grid, time step, turbulence models, modelling of internal geometry, boundary conditions, numerical schemes and convergence criteria. The BPG contain a set of systematic procedures for quantifying and reducing numerical errors. The knowledge of these numerical errors is a prerequisite for the proper judgement of model errors. The strategy of code validation based on the BPG and a matrix of CFD code validation calculations have been elaborated. Besides of the benchmark cases, additional experiments were calculated by new partners and observers, joining the project later. Based on the "best practice solutions", conclusions on the applicability of CFD for turbulent mixing problems in PWR were drawn and recommendations on CFD modelling were given. The high importance of proper grid generation was outlined. In general, second order discretization schemes should be used to minimise numerical diffusion. First order schemes can provide physically wrong results. With optimised "production meshes" reasonable results were obtained, but due to the complex geometry of the flow domains, no fully grid independent solutions were achieved. Therefore, with respect to turbulence models, no final conclusions can be given. However, first order turbulence models like K-e or SST K-w are suitable for momentum driven slug mixing. For buoyancy driven mixing (PTS scenarios), Reynolds stress models provide better results.

In the recent two years the analysis of principal and connective circuitry drawings proved that the principal and connective circuitries of very complicated projects are kept in a single file. Therefore, traditional specialized automated design system are not able to build and draw hybrid circuitries with the fragments of electromechanically networks together with the display of sensors and processors. The number of elements in such project files may reach from a few hundred until a few thousand. As this number is so high, the standard AutoCAD means do not quite fulfill the designers’ needs of working with blocks and their attributes. In this way they choose automated means that do not limit their abilities in preparing technical, assembly and tuning documentation, necessary for the completion of the projects. Therefore, based on the master’s paper, in order to fulfill the aforementioned needs, the building of the graphical data base block attribute system management system has been completed. The objective of the paper is the attributes and management of the graphical data base blocks. The purpose of the paper is to create a system of the graphical database attribute management and the means of using it. The purpose is defined by the following tasks: graphic data bases are analyzed; also the graphical data base blocks, their attributes, constituent parts and their management; the means of using the system in the medium of Auto CAD; based on the master’s paper the system of...
