[en] A PREDICTIVE CACHE SYSTEM FOR REAL-TIME PROCESSING OF LARGE 2D GRAPHICAL DADA / [pt] UM SISTEMA DE CACHE PREDITIVO PARA O PROCESSAMENTO EM TEMPO-REAL DE GRANDES VOLUMES DE DADOS GRÁFICOS

SERGIO ESTEVAO MACHADO LISBOA PINHEIRO 31 March 2004 (has links)
[pt] Atualmente, diversas áreas de Computação Gráfica necessitam processar uma grande quantidade de dados. Para visualizar em tempo-real esses dados é necessário lidar com dois tipos de problema. O primeiro está relacionado com o pouco tempo destinado para realizar os cálculos no processo de síntese de imagem. O segundo problema surge da capacidade limitada de armazenamento dos dispositivos de alta velocidade, como memórias RAM e de textura. Para resolver o primeiro problema, este trabalho utilizou a técnica de multi-resolução para representar os dados gráficos. A representação em multi-resolução permite que a quantidade de dados processada durante a visualização seja praticamente constante. O segundo problema foi resolvido a partir de um sistema de gerenciamento de memória preditivo baseado no modelo de memória virtual. Este trabalho propõe uma arquitetura que permite que qualquer tipo de dispositivo de armazenamento seja inserido. Os dispositivos estão organizados em seqüência. O funcionamento do sistema consiste em reservar um espaço de memória em cada dispositivo e gerenciar esse espaço de forma otimizada. O sistema de predição tem a finalidade de carregar antecipadamente os dados que serão provavelmente utilizados pela aplicação num futuro próximo. Este trabalho propõe um algoritmo de predição adaptativo específico para o problema de visualização. Este algoritmo explora as informações sobre as variações dos parâmetros da câmera e as informações sobre a taxa de transferência de dados, que são usadas para decidir o que deve ser carregado. As informações dos parâmetros da câmera ajudam a determinar os dados que possivelmente serão utilizados pela aplicação. A informação da taxa de transmissão é utilizada para decidir qual o nível de resolução desses dados que devem ser carregados antecipadamente para os dispositivos de alta velocidade. O sistema de gerenciamento de memória preditivo foi testado em aplicações de visualização de imagens de satélite e panoramas virtuais,em tempo-real. / [en] Nowadays, many areas of computer graphics need to process a huge amount of data. In order to visualize the data in realtime time, it is necessary to solve two different problems. The first problem is the limited time available to perform rendering. The second one arises from the restricted capacity of storage high-speed memories, like RAM and texture memories. In order to solve the first problem, this work has used multi-resolution techniques. The multi-resolution representation allows the application to work with a constant amount of data during the rendering process. The second problem has been solved by a predictive management memory system based on the virtual memory model. This work proposes an architecture that allows any storage device to be incorporated in the system. Devices are organized sequentially. The heart of the system consists in allocating an area of memory for each device and managing this space optimally. The predictive system aims to load in advance. The data that will probably be used by the application in the near future. This work proposes a specific adaptative prediction algorithm for the visualization problem. This algorithm exploits the information about the camera parameter variations as well as the data transfer rate, in order to decide what should be loaded. The camera parameters are used to determine which data will possibly be used by the application. The transfer rate is used to decide which resolution level of the data should be loaded to the high- speed devices, in advance. The predictive memory management system has been tested for real-time visualization of satellite images and virtual panoramas.

Customer Value(CV) is a data analytics company experiencing problems presenting the result of their analytics in a satisfiable manner. As a result, they considered the use of a data visualization and business intelligence softwares. The purpose of such softwares are to, amongst other things, virtually represent data in an interactive and perceptible manner to the viewer. There are however a large number of these types of applications on the market, making it hard for companies to find the one that best suits their purposes. CV is one such company, and this report was done on behalf of them with the purpose to identify the software best fitting their specific needs. This was done by conducting case studies on specifically chosen softwares and comparing the results of the studies.The software selection process was based largely on the Magic Quadrant report by Gartner, which contains a general overview of a subset of business intelligence softwares available on the market. The selected softwares were Qlik view, Qlik sense, GoodData, panorama Necto, DataWatch, Tableau and SiSense. The case studies focused mainly on aspects of the softwares that were of interest to CV, namely thesoftwares data importation capabilities, data visualization options, the possibilities of updating the model based on underlying data changes, options available regarded sharing the created presentations and the amount of support offered by the software vendor. Based on the results of the case studies, it was concluded that SiSense was the software that best satisfied the requirements set by CV. / Customer Value(CV) är ett företag som upplever svårigheter med att presentera resultaten av deras dataanalys på ett tillfredsställande sätt.

A historical background of Trinidad and Panorama competitions with an analysis of Ray Holman's 1989 Panorama arrangement of "Life's Too Short".

Remy, Jeannine Irene January 1991 (has links)
This document is directed toward those who have little knowledge about Trinidad, its people, the Carnival activities, and the Panorama competition. This research work should help summarize the evolution of steel drums while providing a transcription of a Panorama score for further scholarly study. The first part of this lecture document includes a brief history and evolution of Trinidad, its people, and musical developments through Carnival. The second portion reports and discusses field research with the Trintoc Invaders in preparation for the 1989 and 1990 Panorama competitions. The third part is a detailed analysis of Ray Holman's Panorama arrangement of "Life's Too Short" for the Trintoc Invaders using theme and variation as the formal structure. Information for this lecture recital document was gathered from written sources in Trinidadian libraries and field work in the Trintoc Invader's pan yard. The source materials: newspaper articles, magazine articles, and books were gathered from the University of the West Indies in St. Augustine and from the West Indian Collection of the Central Library in Belmont. In addition to these materials, interviews were conducted with some older panmen who participated in the very first steel bands. Documents, such as lists of steel bands in Trinidad and Tobago, Panorama results, and judging procedures were obtained from the Pan Trinbago headquarters in Port-of-Spain. Musical information was gathered by rehearsing and playing tenor pan with the Invaders Steel Band Orchestra located in Woodbrook and working closely with their arranger and composer, Ray Holman. Permission was granted to notate his arrangement for analysis and all rights are reserved.

No. of bitstreams: 1 120354.pdf: 3872646 bytes, checksum: 56da6913a3973fd0c5c52ff8e9f1e773 (MD5) Previous issue date: 2014-07-30 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / The text investigates how the 31st PANORAMA DA ARTE BRASILEIRA held in 2009, a periodical exposition host by São Paulo Museum of Modern Art was an singular edition for giving an overview of the so-called Brazilian art, when a minimum number of the artists were actually born in Brazil. Therefore, to find the uniqueness of the 31st edition and its curator Adriano Pedrosa, three fundamental reasons involving the exhibition were observed. Such reasons points to the title of this research: Expositive Scene, Expographic Matter and Curatorial Gesture. Through these general issues, the main idea is to answer questions about the authorship on exposition, on the organization of the art pieces at the exhibition physical space and find hints and the metamorphoses surroundings the exhibit. The academic motivation came from the lack of Portuguese publications about curatorial and exhibitions. The final dissertation in the long run can contribute to a research on curatorship field with a meticulous analysis of a curatorial process and a well recognized curator with major exhibitions on his résumé. / O texto investiga como o 31º Panorama da Arte Brasileira 2009, exposição periódica do Museu de Arte Moderna de São Paulo, foi uma edição singular por traçar um panorama de arte dita brasileira com minoria de artistas nascidos no Brasil. Para encontrar o ineditismo da 31ª edição e do seu curador, Adriano Pedrosa, foram mapeados três motivos fundamentais que envolvem a exibição. Estes motivos dão título a pesquisa: a cena expositiva, a matéria expográfica e o gesto curatorial. Busca-se nestes temas mais gerais responder a questões sobre a autoria em exposição, sobre a organização das obras no espaço expositivo e encontrar rastros e devires que cercam a exibição. O incentivo acadêmico surgiu da raridade de publicações em língua portuguesa sobre curadoria e exposições. A dissertação, ao final, pode contribuir no campo investigativo da curadoria como uma análise detalhada de um processo curatorial e um curador reconhecido com importantes exposições.

One aim of this thesis was to analyze qualitatively the changes occurring after the filling of the lake from the Hydroelectric Power Plant a comprehensive and not piecemeal, for this reason we chose to use the systems theory and the concept of landscape. The work begins with a theoretical discussion, such reflection is important for understanding the discussions throughout the work, especially regarding the concept of landscape, since it is marked by a polysemy.To verify the changes that occurred in the study area after filling the lake Hydroelectric Power Plant, two cards were made from Landsat TM images, for the preparation of this material was used the logarithm NDVI - Normalized Difference Vegetation Index. Besides cartographic material, were also interviewed in the city of Brasilândia-MS, and a photographic survey. / A UHE – Usina Hidrelétrica – Engenheiro Sergio Motta que se encontra entre os estados de São Paulo e Mato Grosso do sul, possui um extenso lago, a formação deste lago e a construção desta UHE alteraram de diferentes formas uma grande área, incluindo área analisada por esta dissertação que abrange a RPPN – Reserva Particular do Patrimônio Natural – Cisalpina, localizada no município de Brasilândia-MS e as áreas adjacentes. Um dos objetivos desta dissertação foi analisar qualitativamente as transformações ocorridas após o enchimento do lago do UHE a partir de uma visão abrangente e não fragmentada, por esta razão optou-se pela utilização da teoria sistêmica e do conceito de paisagem. O trabalho inicia-se com uma reflexão teórica, tal reflexão é importante para o entendimento das discussões realizadas ao longo do trabalho, principalmente a respeito do conceito de paisagem, visto que este é marcado por uma polissemia. Para verificar as mudanças que aconteceram na área estudada após o enchimento do lago da UHE, foram confeccionadas duas cartas a partir de imagens TM do satélite Landsat, para a elaboração deste material foi empregado o logaritmo NDVI – Normalized Difference Vegetation Index. Além do material cartográfico, também foram realizadas entrevistas no município de Brasilândia-MS, e um levantamento fotográfico.

Key Views for Visualizing Large Spaces

Cai, Hongyuan 08 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Image is a dominant medium among video, 3D model, and other media for visualizing environment and creating virtual access on the Internet. The location of image capture is, however, subjective and has relied on the esthetic sense of photographers up until this point. In this paper, we will not only visualize areas with images, but also propose a general framework to determine where the most distinct viewpoints should be located. Starting from elevation data, we present spatial and content information in ground-based images such that (1) a given number of images can have maximum coverage on informative scenes; (2) a set of key views can be selected with certain continuity for representing the most distinct views. According to the scene visibility, continuity, and data redundancy, we evaluate viewpoints numerically with an object-emitting illumination model. Our key view exploration may eventually reduce the visual data to transmit, facilitate image acquisition, indexing and interaction, and enhance perception of spaces. Real sample images are captured based on planned positions to form a visual network to index the area.
