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

Pré-sal e o novo marco regulatório: um estudo sobre o fundo social

This work intends to discuss about the current happenings in oil sector, and how the recent discovery of huge oil reserves on the layer known as Pre-Sal can positively transform in the socioeconomic context, the country. The impact of this huge quantity of natural resources it depends on the legislative policies adopted for the exploration and production (E & P) in the Pre-Salt layer, and the way in which laws are imposed for distribution of such resources. Therefore, it is made a shortly background of the laws from oil exploration, production and distribution, since the monopoly of Petrobras, to nowadays. To this end, an analysis is performed about the Oil Law, and about the possible legislative changes with the new Regulatory Framework. This monograph attempts to prove, based on historical data, socioeconomic facts, and international experiences, using either comparative statistical, that with the discovery in the Pre-Salt area, the best way to optimize the use of these resources, mainly the reduction of social inequality and economic contrasts, a legacy from colonization, would directly those recipes to a National Development Fund, the Social Fund, established by law for the new Regulatory Framework

Análise comparativa do mercado imobiliário em Cidades Médias: a oferta de apartamentos, casas e terrenos urbanos em Campina Grande – PB, Mossoró – RN e Passo Fundo – RS

This presente monograph propose the analysis and discussion of the production of urban space and the processes of their structuring intraurbana from the dynamics of the real estate market into three Medium-sized Cities, Campina Grande - PB, Mossoró - RN and Passo Fundo - RS, whereas the various agents producing this space, in a comparative perspective. From this urban dynamic search to analyze the processes and relations present in these spaces, which are important for its production. From the compilation of real estate advertisements in local newspapers, are analyzed offerings of urban land, houses and apartments in each one of these cities by highlighting their locations and differentiated prices. Thus, working with data from real estate ads from the period 1995 - 2010 and a comparative perspective of the characteristics of real estate markets of three medium-sized cities, it tried to apprehend processes that are common between them and other individuals, to each one. Therefore the comparative analysis developed in this monograph sought to verify whether there are similarities between the cities in relation to the trends of concentration/spatial dispersion of bids and movements throughout time, in addition to a further intensification of the activities of real estate agents in face of such trends and offerings. In addition, we sought to remove a set of problematization that allow them to understand with more acute, in this set of medium cities of Brazilian urban network, processes of change that is already being discussed in the recent period by ReCiMe.

Alterações morfohidrográficas do setor de fundo de vale do rio Piracicaba sob influência do reservatório de Barra Bonita (SP)

O homem modifica o ambiente ao seu redor gerando alterações “nos elementos que se encontram em contato direto com suas atividades, como a cobertura vegetal, as formas do relevo e a rede hidrográfica” (CASSETI, 1994). Assim, destacam-se as áreas submetidas ao represamento, cujos reflexos incidem diretamente sobre as formas do relevo. Desta forma, a geomorfologia atua como uma ciência de análise das alterações ocorridas na rede de drenagem e nas feições geomorfológicas, e a cartografia geomorfológica antecipa-se como instrumento da geomorfologia. O objetivo principal da pesquisa foi identificar e analisar as alterações morfohidrográficas e morfométricas provocadas pela construção do reservatório de Barra Bonita no curso final do Rio Piracicaba. A orientação metodológica vincula-se à Teoria Geral dos Sistemas Aplicada à Geografia e à análise da dinâmica de sistemas morfohidrográficos. Para as técnicas, foram confeccionados mapas geomorfológicos e de uso e ocupação das terras dos anos de 1962 (ano anterior à construção da barragem) e 2007 (selecionado como ponto de partida para a análise das alterações morfohidrográficas). Em 1962 existiam barras de meandro, canais e meandros abandonados, terraços fluviais, diques marginais, lagos e lagos de meandros. Em 2007 estes são comprometidos devido à mudança de nível de base local, fato demonstrado pelo desaparecimento de meandros e canais abandonados nas planícies aluviais, fragmentação de terraços fluviais, mudança de foz pelos canais tributários do rio principal e surgimento de novas lagoas. Para o uso, no ano de 1962 existiam grandes áreas de vegetação de “campo úmido”, atrelado à feição geomorfológica “planície aluvial”, que se encontrou alagada no ano de 2007. Foram também calculados os índices de sinuosidade, densidade de meandramento, número de meandros, área... (Resumo completo, clicar acesso eletrônico abaixo)

Análise da reversão do fundo de latas de alumínio para bebidas - Buckle

This work approaches the main methods of plastic deformation of metals, with a focus on the deep drawing process. The mechanical properties were evaluated with the tension tests. It is presented the aluminum alloys designation, followed by applying heat treatments and the designation of tempers. The manufacture of aluminum beverage cans is described step by step, in general terms. The main objective is to analyze how different cans background geometries have great influence on the dome reversal. To be able to achieve the goal it was necessary to use cans of different manufacturers, which were used in buckle tests to obtain the reversal pressures, tensile tests and geometric analysis. Finally empirical equations were obtained correlating these variables, and it was observed that the conformation of reforming change significantly it's behavior

Considerações sobre a atualidade da formação cultural/educacional: novos desafios para a pesquisa

This paper aims to draw some outlines of what I understand to be background for possible investigations that examine the cultural / educational problems in Brazil from the perspective of Critical Theory. Under the light of these outlines I intend to present two directions of research which are the main objectives of the research project I develop within the Department of Educational Psychology of College of Sciences and Letters of Unesp in Araraquara. In particular, it is necessary to understand the internal deformation that education suffers as a concrete substance of the teaching process in schools, which makes an empirical investigation how the cultural industry’s schemes become present in the “didactic pedagogical scene” necessary. On the other hand, the elucidation of this problem requires a theoretical investigation about the broader process of constitution of today’s subjectivity under the impact of that industry. Both goals set forth herein are intended to provide subsidies to make readings about new educational demands possible in Brazil.

Fundo Nacional do Idoso e as políticas de gestão do envelhecimento da população brasileira

Demographic census from the last decades of the twentieth century began to reveal a tendency concerning the increasing average age of the population. The Brazilian government began introducing ways to manage the effects and consequences of this trend, the most recent being the creation of the "Fundos do Idoso" (Funds for seniors) in the Federal, state and municipal spheres. That law allows transferring federal taxes from common citizens and companies to the funds. This article is specifically written as a critical examination of this governmental initiative towards the problem of an ageing population from the point of view as to how the law has been implemented. With the creation of the funds there will be the enlargement and improvement of services destined for seniors. However, the law mentioned above does not predict an active participation of the seniors in the management of this funds and policies that will come as result.

Odontologia baseada em evidências: otimizando a prática e a pesquisa

Clinical decisions in dentistry are often based on the knowledge obtained during graduation, clinical experience, information shared with colleagues and professor, textbooks, seminars, conferences and continuing education courses. However, it is necessary to know if this information is derived from scientifically validated researches since too much information may complicate this process. Initially in medicine and later in other health areas a method which enables a critical evaluation of scientific papers related to a specific issue and also, whenever it is possible, an evaluation of the results by meta-analysis,was developed by Cochrane in order to reduce the bias towards all information obtained. The aim of this work is to present some aspects of the Evidence Based Dentistry (EBD) and to show how this methodology can be used to better substantiate scientifically the clinical decision of the dentist and improve researches design with scientific validity. The paper discusses editorial trends focused on the EBD, shows the differences between a systematic and a conventional review, describes data about Cochrane and the advantages of scientific evidence synthesis and the implications of EBD for clinical practice and research as well as recommendation grades and evidence levels of general scientific studies.

Conhecimento sobre saúde bucal e práticas desenvolvidas por professores do ensino fundamental e médio

Introduction: The oral health education is a process that aims to transform attitudes and behaviors and to form habits for the benefit of individual health. For this to occur, it is necessary to strengthen and continuous repetition, as possible in the school environment. Objective: To analyze teachers’ knowledge about oral health, practices developed in the school environment, as well as the participation of dentists in guiding teachers of primary and secondary schools. Subjects and method: We used a semi-structured questionnaire with open and closed questions about teacher training, received guidance on oral health during their training, development of oral health issues in the classroom and knowledge on the subject . Results: Of the total respondents (n = 221), only 77 (34.8%) said they had guidance on oral health in their training to be a teacher. 70 (31.7%) said they did not develop oral health issues in the classroom and 91 (41.2%) stated no interaction between dentist and professor. We observed deficiency in teachers’ knowledge about certain issues related to dental health. There was statistically significant association between the dentist’s guidance to teachers and the development of oral health actions and the teacher’s knowledge about the location of the first permanent molar eruption (p <0.01). Conclusion: This study conclude that although most educators develop educational practices on oral health in the school environment, there is a deficiency in understanding by teachers of certain subjects, making it necessary a greater participation of the dentist in the transmission of technical and scientific knowledge to them.

Exigências familiares e do trabalho: um equilíbrio necessário para a saúde de trabalhadores e organizações

This article aims, through a theoretical essay, to promote a reflection about the new roles played by people in families, at work and at the society in general. Based on papers and scientific bibliography, it broaches the changes at the contemporary society, linked to changes on world of work and family relationships, focused on the unbalance at family-work relation. Some current organizational initiatives were cited as plans of prevention and improvement of worker health, which affect their relations. It was considered the need of reconstruction of gender stereotypes and reducing the inequality of opportunity between people as focal points for changing a current scenario, which prevails in the lack of balance between requirements that can generate negative consequences both for health the individual and their families and for the organization.
