Denna kandidatuppsats tar upp tankar kring hur de svenska biograferna kan komma att förändras i framtiden. Uppsatsen innehåller en historisk bakgrund om biografen, en enkätundersökning om film och biografvanor i Skövde och intervjuer med ett flertal personer inom den svenska filmbranschen. Uppsatsen fokuserar sig i grund och botten på tankar kring hur biografen kommer att förändras för biografpubliken där visningsförhållanden och tillgång till film är två viktiga aspekter. Uppsatsen lägger extra stor vikt vid vad som kommer att förändras i och med att den svenska biografen går in i en ny digitaliseringsera.

3D graphics pipeline can be divided into two subsystems: geometry subsystem and rendering subsystem. In this thesis, the geometry subsystem is implemented based on the specification of OpenGL ES. The major operations in the geometry subsystem are transformation, lighting, backface culling, and clipping. We propose a new architecture for the geometry subsystem that reorganizes the functions of different hardware components at three different pipeline stages so that three vertices can be processed at the same time by efficiently utilizing the hardware components. The same type of operations is executed at the same hardware component but maybe in different pipeline stages in order to increase the hardware utilization efficiency and to reduce the overall area cost. We also improve the designs of individual hardware components proposed in previous paper so that the area cost can be reduced while still meeting the operation accuracy. The interfaces and communication registers among the hardware geometry subsystem, another hardware rendering subsystem and OS drivers are also designed so that the complete OpenGL API software programs can be executed in the integrated 3D graphics system. In addition to the traditional RTL verification, the complete system is also mapped to a FPGA board to demonstrate the rendered 3D graphics pictures on the screen. Thus, the complete hardware/software integration (including OpenGL API application software, OS drivers, and graphics hardware) is verified.

Ce mémoire de thèse de doctorat est structuré en deux parties. Dans la 1ère partie, une nouvelle approche traitant la caractérisation géométrique et mécanique est décrite. La modélisation géométrique de tissu 3D interlock est corrélée avec les paramètres de tissage afin de mieux prendre en compte ces paramètres. Le tissage de tissu 3D interlock est décrit en détail. Par la suite, une étude a été menée pour mieux comprendre les changements qui se produisent dans une mèche de carbone lorsque cette dernière est intégrée dans un renfort. Un coefficient de transfert des propriétés mécaniques a été proposé permettant une meilleure compréhension de l’influence des paramètres structuraux sur les propriétés d’un composite. Dans la 2eme partie du mémoire, un système de mesure in situ pour les composites a été développé. Ce système comporte un capteur souple et un module de traitement de données et d’amplification des signaux. Le capteur fibreux développé durant nos recherches a été inséré pendant le tissage comme un fil de trame. Le système a été testé sur une plaque en composite, contenant les renforts en 3D interlock, en traction. Le capteur suit fidèlement les déformations de la plaque composite jusqu’à la rupture. / This thesis is divided in two parts. In the first part a geometrical modelling approach has been developed in tandem with weaving parameters. The reinforcements were woven on a modified conventional loom to study the geometry of these structures. Their weaving has been described in detail. The weaving parameters have been correlated to the modelling approach. The meso structural modelling approach is capable of predicting essential reinforcement geometrical characteristics at meso structural level without being too complicated. Furthermore, mechanical characterization of 3D interlock reinforcements has been carried out in such a way that a track of mechanical properties during the complete production cycle has been maintained. A novel parameter called strength transfer coefficient was proposed which allows better understanding of the influence of structural parameters on the final properties of the composite. In the second part of the thesis an online structural health monitoring system which is composed of a textile based sensor and signal amplification and treatment module, has been developed. This system is capable of detecting structural deformations in the composite as the sensor is integrated during the manufacturing of the reinforcement and can follow its deformation pattern when composite is subjected to tensile loading in a real time.

Neste estudo é apresentado um procedimento de análise de dados magnéticos em casos de presença de magnetização remanente para, ao final do processo, a realização de uma inversão mais rápida e fiel ao comportamento do alvo em sub-superfície. O procedimento é composto por seis passos: (1) Delimitação lateral do alvo; (2) Estimativa de suas profundidades; (3) Estimativa das direções de inclinação e declinação aparentes de seu vetor de magnetização total; (4) Modelagem inicial com inferência de valores de susceptibilidades oriundos de estudos geológicos anteriores sobre o alvo e/ou sua região; (5) Inversão dos dados magnéticos utilizando o modelo inicial; e (6) atribuição das características magnéticas do passo (3) sobre o modelo de contraste de susceptibilidade magnética obtido com a inversão para a modelagem final do alvo, conhecendo-se seus vetores de magnetização induzida, total e, por subtração vetorial de ambos, remanente. Este procedimento foi aplicado a 108 casos sintéticos e a 8 casos reais pertencentes às províncias ígneas do Alto do Paranaíba e Rondoniana-San-Ignácio. Os resultados do uso deste procedimento indicaram uma recuperação das direções das componentes de magnetização com erro menor que 10%, em casos sintéticos, uma redução de mais de 20% no tempo de inversão com o uso de modelos iniciais, e qualitativamente, apresentaram modelos mais próximos dos originais (nos casos sintéticos) e geologicamente factíveis nos casos reais. / In this study, we present a procedure of analysis of magnetic data when remanence is present in order to, at the end of the process, obtain an inversion faster and more reliable inversion. The procedure is composed of six steps: (1) Estimation of the borders of the target; (2) Estimation of its depths; (3) A sweeping for the total apparent inclination and declination directions; (4) Initial modeling of a synthetic body, based on the recovered geometry and depth, on the directions of inclination and declination of the total magnetic field, and on previous analysis of the target and/or its region; (5) Inversion of magnetic data using the initial model; and (6) Attribution of the magnetic features of step (3) to the model recovered by the inversion for a final modeling of the target, estimating as well its remanent magnetization; the last through the vectorial resultant of the induction and total magnetization subtraction. This procedure was applied to 108 synthetic and to 8 real cases from the Alto do Paranaíba and Rondonian-San Ignacio Igneous Provinces. Their results pointed out that the error between the recovered directions of the magnetization components and the original values, in synthetic cases, was smaller than 10%; The inversions had their processing-time reduced in more than 20% and, qualitatively, presented models were more similar to the original (synthetic cases) and geologically feasible (real cases).

This project deals with the design and implementation of the extensible programmable environment intended for the creation of various 3D simulations, specifically targeted for testing of the algorithms and creation of applications from the field of computer vision and robotics. Environment VISIMBOX was implemented in c# programming language and uses OpenGL as back-end for hardware accelerated rendering.

Paralleling with development of computer technology, Computer-Aided Design (CAD) has been researched and introduced into industry since the 1960s. Until the mid-1980s, CAD means Computer-Aided Drafting in architectural field because the majority of practicing architects originally used computer as an electronic drafting tool to produce construction drawings. However, now computer 3D visualization technology as a design aided tool is impacting the architectural design process. In this research, a review of architectural representation in the early design phases is given. Additionally, a literature review of CAD development is presented as well. As a focus of this research, computer 3D visualization technology has been researched as a design aid. The emerging use of computer 3D visualization technology in some educational settings is also reviewed. Within this research, three Case Studies are presented to provide insights of how computer 3D visualization technology may impact architectural design process, design service quality, and client-architect?s relationship.

A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations. Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other. Then also the handling and storage of three-dimensional data with the information model CityGML is investigated. A specification of the requirements and characteristics that the customer, the City Planning in Gothenburg, looks are essential for building modeling in 3D has also been established. The final result shows of 4% increase in the plane of 3D buildings compared to primary map. The increase would be slightly greater if the comparison is made on the volume instead. The results also revealed that the increase in plan is something that has occurred during the creation of the roof constructions, which was something that I couldn’t have affected during the work. The results also show that the CityGML is an appropriate information model for storage and handling of 3D. Gothenburg still have insufficient knowledge of CityGML, which is also one of the reasons why the information model hasn’t been implemented in the municipality work with 3D models.
