Metodos de Processamento de Imagens para Determinação de Dano em DNA

Patente de invenção de métodos para processamento de imagens obtidas a partir de amostras preparadas 'cbnforme protocolo para reajízação de teste do cometa, particularmente corado pela prata. Este teste é amplamente utilizado para avaliação de genotoxicidade de substâncias. Há sistemas automatizados que analisam cometas corados por substâncias fluorescentes. A coloração de prata é uma técnica pouco difundida pela falta de tecnologia de análise digital automatizada e tem desempenho semelhante às técnicas com fluorescência, porém, é de baixo custo, rápida execução, não depende de microscópios de fluorescéncia e não utiliza produtos mutagênicos em seu protocolo.

Direito, técnica, imagem: os limites e os fundamentos do humano

Esta coletânea de artigos foi desenvolvida a partir de reflexões produzidas em diferentes edições do Seminário Brasileiro sobre o Pensamento de Jacques Ellul, filósofo e sociólogo francês que discutiu, em mais de 50 livros e centenas de artigos, a condição e o destino do homem na sociedade técnica, termo por ele utilizado para referir-se à sociedade contemporânea. Foram reunidos artigos produzidos por pesquisadores do Brasil, Canadá, França e Inglaterra, com a maior parte dos textos oriundos da pesquisa e das reflexões de alunos, pesquisadores e professores do Programa de Mestrado em Direito da Unesp, campus de Franca. Os artigos foram divididos em duas partes, com a primeira tratando principalmente da ênfase de Ellul na técnica e na tecnologia como os verdadeiros fundamentos do poder na sociedade moderna. Para Ellul, o progresso técnico já teria engendrado um fenômeno de proletarização generalizada, que abrange toda a humanidade e todos os aspectos da vida humana, superando a dimensão puramente econômica. Na segunda parte, os estudos transpassam as questões políticas e desembocam na análise das técnicas de dominação dos corpos e das mentes, buscando aprofundar a perspectiva elluliana diante do Direito e da Bioética, além dos muitos e tortuosos significados da imagem na sociedade atual

Paralelização de algoritmos de trimap utilizando a arquitetura Cuda

Techniques of image combination, with extraction of objects to set a final scene, are very used in applications from photos montages to cinematographic productions. These techniques are called digital matting. With them is possible to decrease the cost of productions, because it is not necessary for the actor to be filmed in the location where the final scene occurs. This feature also favors its use in programs made to digital television, which demands a high quality image. Many digital matting algorithms use markings done on the images, to demarcate what is the foreground, the background and the uncertainty areas. This marking is called trimap, which is a triple map containing these three informations. The trimap is done, typically, from manual markings. In this project, methods were created that can be used in digital matting algorithms, with restriction of time and without human interaction, that is, the creation of an algorithm that generates the trimap automatically. This last one can be generated from the difference between a color of an arbitrary background and the foreground, or by using a depth map. It was also created a matting method, based on the Geodesic Matting (BAI; SAPIRO, 2009), which has an inferior processing time then the original one. Aiming to improve the performance of the applications that generates the trimap and of the algorithms that generates the alphamap (map that associates a value to the transparency of each pixel of the image), allowing its use in applications with time restrictions, it was used the CUDA architecture. Taking advantage, this way, of the computational power and the features of the GPGPU, which is massively parallel

Formação da imagem do professor na Folha de S. Paulo durante a greve de 2010

The objective of this paper is to discuss the construction of the image of São Paulo state public schools teachers in the public sphere, by the media and the trade union press, and see how that image is formed in both of them, without making any comparisons, from the covering of 2010 strikes by newspapers Folha de S. Paulo and Jornal da Apeoesp. This paper uses as theoretical basis the study of Media Hegemony, the concept of Radical Media and Public Sphere, as well as the relationship between them and social movements. It also considers the observation of the history and characteristics of trade union press and the Standards of Manipulation by the Press, proposed by Perseu Abramo. The chosen method was the identification, selection and organization of stories about education published by Folha de S. Paulo during the period; the application of Abramo’s proposed manipulation standards on the stories about the strike; research, selection and observation of print publications (Jornal da Apeoesp and newsletters Apeoesp Urgente) about the strike, published by Apeoesp during the same period

Comparação entre metodologias de controle de qualidade em mamografia digital

The best way to detect breast cancer is by screening mammography. The mammography equipments are dedicated and require a rigorous quality control in order to have a good quality image and to early detect this disease. The digital equipment is relatively new in the market and there isn’t a national rule for quality control for several types of digital detectors. This study has proposed to compare two different tests manuals for quality control provided by the manufacturers of digital mammography equipments, and also compare them to the “European guidelines for quality assurance in breast cancer screening and diagnosis “(2006). The studied equipments were: Senographe 2000D from General Electric (GE) and the Hologic Selenia Lorad. Both were digital mammography equipments, the GE unit presents an indirect digital system and the other presents a direct digital system. Physical parameters of the image have been studied, such as spatial resolution, contrast resolution, noise, signal-tonoise ratio, contrast-to-noise ratio and modulation transfer function. After that, a study of the importance of quality control and the requirement to implement a Quality Assurance Program has been done. One data collection was done to compare those manual, it was done by checking which tests are indicated and the minimum frequency which they should be conducted in accordance with each manufacturer. The tests were performed by different methodologies and the results were compared. The examined tests were: the breast entrance skin dose, mean glandular dose, contrast-to-noise ratio, signal-to-noise ratio, automatic exposure control and automatic control of density, modulation transfer function, equipment resolution, homogeneity and ghost

Seleção de áreas potenciais para implantação da zona de processamento e exportação de Fernandópolis - SP utilizando geotecnologia

The implementation of an Export and Processing Zone (ZEPs) brings several benefits to the local, state and federal economy, but often, only socioeconomic factors are considered, apart from several other factors that should be analyzed, such as the environment. In this context of industrialization and the struggle for sustainable development, this work propose to incorporate the environmental variable in the decision process for establishing industrial areas, in particular, the ZPE in the city of Fernandópolis, São Paulo state, Brazil, by examining several physical and environmental factors such as slope intervals, geological features, pedological factors and land use. Developed using a multicriteria analysis, a model has been elaborated, where these factors have received a proportional value according with their importance, supported by a GIS tool (Geographical Information System) and remote sensing products, such as images from CBERS satellite and SRTM radar, showing the suited areas for industrial activities, considering environmental conditions. This model may assist to take better decision about the ZPE implementation area and to reduce the negative environmental impacts that would result of poorly planned locations

A implantação da televisão digital terrestre na Espanha

This monograph has as objectives introduce digital terrestrial television, describing the process of installation of this in Spain, their technical qualities and possibilities of change and innovation that this creates. The exposure of the different chapters of this monograph has a objective presenting and discussing what are the characteristics of this new technology, your birth, what is its importance in communication and how this is inserted inside the Spanish reality. The introduction of digital terrestrial television in Spain is cited as an example of a pioneer in the development and installation of this new technology, but also appears as a nation that has come a way with some economic failures, reaching one of the largest cases of delayed installation of digital television in Western Europe. Making use of the European system for digital terrestrial television (DVB-T - Digital Video Broadcasting) it was possible some advances as the quality of communication and strengthening national public television system, but many vices of analog system were transferred this new system, as the concentration of channels to a foreign group and interactivity opportunities were wasted. Digital terrestrial television can provides better picture quality and sound, possibility of interactivity, mobility, hypermedia and multiprogramming, while the latter tool may lead to the democratization of media, opening it to other social agents. Going much further than just a technological advancement, digital television is strongly connected with the politics and the economy of the nation in which it operates
