New Global Cities in Latin America and Asia

New Global Cities in Latin America and Asia: Welcome to the Twenty-First Century proposes new visions of global cities and regions historically considered “secondary” in the international context. The arguments are not only based on material progress made by these metropolises, but also on the growing social difficulties experienced (e.g., organized crime, drug trafficking, slums, economic inequalities). The book illustrates the growth of cities according to these problems arising from the modernity of the new century, comparing Latin American and Asian cities. This book analyzes the complex relationships within cities through an interdisciplinary approach, complementing other research and challenging orthodox views on global cities. At the same time, the book provides new theoretical and methodological tools to understand the progress of “Third World” cities and the way of understanding “globality” in the 21st century by confronting the traditional views with which global cities were appreciated since the 1980s. Pablo Baisotti brings together researchers from various fields who provide new interpretative keys to certain cities in Latin America and Asia

Recuperação por conteudo em grandes coleções de imagens heterogeneas

Orientador: Alexandre Xavier FalcãoTese (doutorado) - Universidade Estadual de Campinas, Instituto de Matematica, Estatistica e Computação CientificaResumo: A recuperação de imagens por conteúdo (CBIR) é uma área que vem recebendo crescente atenção por parte da comunidade científica por causa do crescimento exponencial do número de imagens que vêm sendo disponibilizadas, principalmente na WWW. À medida que cresce o volume de imagens armazenadas, Cresce também o interesse por sistemas capazes de recuperar eficientemente essas imagens a partir do seu conteúdo visual. Nosso trabalho concentrou-se em técnicas que pudessem ser aplicadas em grandes coleções de imagens heterogêneas. Nesse tipo de coleção, não se pode assumir nenhum tipo de conhecimento sobre o conteúdo semântico e ou visual das imagens, e o custo de utilizar técnicas semi-automáticas (com intervenção humana) é alto em virtude do volume e da heterogeneidade das imagens que precisam ser analisadas. Nós nos concentramos na informação de cor presente nas imagens, e enfocamos os três tópicos que consideramos mais importantes para se realizar a recuperação de imagens baseada em cor: (1) como analisar e extrair informação de cor das imagens de forma automática e eficiente; (2) como representar essa informação de forma compacta e efetiva; e (3) como comparar eficientemente as características visuais que descrevem duas imagens. As principais contribuições do nosso trabalho foram dois algoritmos para a análise automática do conteúdo visual das imagens (CBC e BIC), duas funções de distância para a comparação das informações extraídas das imagens (MiCRoM e dLog) e urna representação alternativa para abordagens que decompõem e representam imagens a partir de células de tamanho fixo (CCIf)Abstract: Content-based image retrieval (CBIR) is an area that has received increasing attention from the scientific community due to the exponential growing of available images, mainly at the WWW.This has spurred great interest for systems that are able to efficiently retrieve images according to their visual content. Our work has focused in techniques suitable for broad image domains. ln a broad image domain, it is not possible to assume or use any a p1'ior'i knowledge about the visual content and/or semantic content of the images. Moreover, the cost of using semialitomatic image analysis techniques is prohibitive because of the heterogeneity and the amount of images that must be analyzed. We have directed our work to color-based image retrieval, and have focused on the three main issues that should be addressed in order to achieve color-based image retrieval: (1) how to analyze and describe images in an automatic and efficient way; (2) how to represent the image content in a compact and effective way; and (3) how to efficiently compare the visual features extracted from the images. The main contributions of our work are two algorithms to automatically analyze the visual content of the images (CBC and BIC), two distance functions to compare the visual features extracted from the images (MiCRoM and dLog), and an alteruative representation for CBIR approaches that decompose and represent images according to a grid of equalsized cells (CCH)DoutoradoDoutor em Ciência da Computaçã

Space Station Systems: a Bibliography with Indexes (Supplement 8)

This bibliography lists 950 reports, articles, and other documents introduced into the NASA scientific and technical information system between July 1, 1989 and December 31, 1989. Its purpose is to provide helpful information to researchers, designers and managers engaged in Space Station technology development and mission design. Coverage includes documents that define major systems and subsystems related to structures and dynamic control, electronics and power supplies, propulsion, and payload integration. In addition, orbital construction methods, servicing and support requirements, procedures and operations, and missions for the current and future Space Station are included

The Language LinF for Fractal Specification

This article presents the language LinF for L-System specification. L-Systems are formal string rewriting systems introduced in 1968 by the botanist Aristid Lindenmayer that are used to model fractal images. LinF allows the definition of three-dimensional fractals and stochastic fractals. Together with the LinF definition this paper presents the implementation of cFLC, an OpenGL-based system that generates fractal images from LinF specifications. Results obtained through the LinF formalism show the ease of use and generality of the developed tools with respect to the existing literature.
