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

Analise do sistema de medição em peças aeronaúticas através do estudo de R&R (repetibilidade e reprodutibilidade)

The Measurement System Analysis (MSA - Measurement System Analysis) is a statistical methodology developed to study and analyze the behavior of the measurement systems, and, therefore, allow the increased of the confidence readings performed by measuring instruments. It’s widely used in the automotive industry since the 90’s and is a mandatory requirement for the approval of the parts according to ISO Standard of the automotive sector. However, the aerospace industry doesn’t require this type of Study, once which the vast majority of aeronautics parts have characteristics (dimensions) with very tight tolerances, closed, ie, at the home of microns. This work aims to create lists of recommendations for definitions of measuring instruments in developing of control plans, which correlates tolerances fields of characteristics for different settings and acceptance of the instrument, classified as optimum, recommended and not recommended, through of the study of R&R (Repeatability and Reproducibility) in aeronautics parts. Every methodology of the experimental part was based on modern strategy of continuous improvement, the DMAIC (Define Measure Analyze Implant Control), in order to achieve better measurement method used in the control of milling aeronautics parts, identifying and reducing the variations of the measurement process. The results of the R&R Study in large part of measuring instrument manuals were considered acceptable and/or recommended, ie with values of %P/T and %RR lower than 30%, providing statistical data which have enabled the elaboration of tables of recommendations, which, from this work, have turned into very important documents and aid for Process Engineering, having in their hands a technical study able to identify which is the most appropriate instrument to get a more robust dimensional...

Sistemas técnicos agrícolas e cafeicultura científica globalizada no sul de Minas Gerais

The study aims to analyze the mechanization of the main coffee growing region in the south of Minas Gerais, in force, especially from the 1970s. But you get new content from the1990s, with the introduction of new information technologies. The use of machines in production processes appear as one of the great transformations of coffee in the period modern after globalization, requiring a labor more specialized, although resulting in unemployment in rural areas. So in the period of globalization new technologies gradually replace manual work. In the coffee farm, the old ways of the production (that handed down from father to son) aren't accepted by the global scientific agriculture (Santos, 2000:88). They are considered inefficient and low quality, but not attendant of patterns the international market. The national companies producing agricultural machines for coffee with emphasis on the company Pinhalense Agricultural Machinery SA believe that the producers of the region are its biggest customers in the country, considering the degree of mechanization more pronounced compared to other coffee growing regions. Analyze the importance of the coffee region with a contribution in the indicators of export and trade surplus in the Brazil and State of Minas Gerais

Novas responsabilidades para o professor na educação básica

The goal of this study was to identify some of the new responsibilities that have been assigned to the elementary school teachers , under the mediation of continuing education courses . We start from the idea that these courses , especially those offered by the SECADI, are proposed teachers and aims to train them for a performance at school that exceeds the activity of teaching in the classroom . The teacher has been summoned to attend these courses in which is prepared to act on school performing tasks rather related to the care of students than teaching , assisting them in their basic needs such as health, protection, inclusion and human rights. Asked ourselves if there was a reconfiguration of the responsibilities of education professionals in order to make use of oneself given by the State. We chose as sources of research documents the SECADI such as legislation , manuals and instructional materials that will proceed to the analysis , in each course , the target populations privileged , purpose, remuneration and certification , pre - requirements to participate in the courses and duration ; partnerships involved if the courses are face , semi-distance or distance ; activities that teacher should develop in school after completion of the courses ; loads hourly . We will seek to analyze the documents and materials of School programs that Protects, School Health Program , Network Education for Diversity. The theoretical and methodological framework is dialectical and historical materialism, from assumptions which we choose as the class character of society in capitalism and alienation as a phenomenon that affects the work in all its manifestations . Thus , our general hypothesis is that the enrichment tasks of teachers in public schools can contribute to basic disposition Teacher education

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

Os professores e o consumo de projetos que chegam à escola: o caso do Projeto Lego Education

O estudo proposto focaliza o modo como os professores recebem, consomem e se apropriam de projetos educativos que são implementados nas escolas de ensino fundamental. Trata-se de um estudo de caso que focaliza a implementação, iniciada em 2008, do Projeto Lego Education em escolas de uma rede municipal de ensino no interior paulista. A implementação do referido projeto insere-se em um contexto mais amplo marcado pelo crescimento de um “rentável mercado formativo” (Nóvoa, 1999) entre nós atualmente. Diante desse contexto, surge uma questão: Como foi, para os professores daquela rede de ensino, a inserção do Projeto Lego Education em seu trabalho docente e como os mesmos lidam com o projeto atualmente? Para tentar responder a essa questão o presente estudo foi realizado com os professores que foram capacitados e atuaram na implementação do projeto, a partir de entrevistas semi-estruturadas e observações. Objetivou-se investigar como o referido projeto foi apropriado (de Certeau, 1994) pelos professores na sua implementação e como os mesmos percebem o projeto atualmente. Pretendeu-se identificar, assim, maneiras pelas quais os professores relacionam-se com materiais didáticos, livros/guias do professor e cursos de capacitação docente ligados ao Projeto Lego Education, procurando caracterizar as maneiras como os mesmos se apropriam e consomem (de Certeau, 1994) tais produtos que lhes são dirigidos. Nesse estudo foi realizada também a análise de documentos relacionados ao Projeto Lego Education (sites das empresas envolvidas, manuais e revistas, entre outros materiais), focando em como esses materiais se referem ao professor e sua prática em sala de aula. A inserção nas escolas públicas de projetos que, como o LEGO, são provenientes de empresas privadas, aponta... (Resumo completo, clicar acesso eletrônico abaixo)

This study shows the ability to reduce costs, increase productivity and elimination of defects that the methodology developed with the fusion of Lean Manufacturing with Six Sigma allows

Sílabas métricas em Terenciano Mauro, De Syllabis, 997-1299

This monograph addresses to the study of Latin metrical notions and concepts as showed in the volume VI of Heinrich Keil’s work, entitled Grammatici Latini (GL): Scriptores Artis Metricae. From that book, it was chosen Terentianus Maurus’s work for corpus, particularly the excerpt between verses 997 and 1299 of De Syllabis, a part of Terentianus’s De Litteris, De Syllabis, De Metris, which is a metric manual written in verses. Until now, there are only three translations of that text into modern languages: two in Italian (one of them was used for comparison with the translation prepared for this monograph) and a French one. That work still contains many reference notes whenever Terentianus Maurus uses ancient authors to demonstrate his explanations on Metrics. Thus this research intends to join in other analysis made on Latin metrical manuals that have already been translated or are still going to be, as well as to notice the importance and the specific value of meter in ancient poetry

Análise de condicionantes geológico-geotécnicos para o rompimento de pequenas e médias barragens de terra: estudo de caso na bacia do rio Jaguari Mirim no município de São João da Boa Vista, SP

The act of containing water is one of the most practiced by the civilizations along history, in the will to increase the offer of water to many uses. The raise of environmental worries surround many human activities has given a big attention to dams. Indeed, the environmental consequences about dams are proporcional to their size, what gives to the big dams a more detailed Project and a bigger political concerning that increases the built, estability and maintenance of them. Then, the projects of medium and small dams are weak, limitaded to handbooks, textbooks and empirical recommendations, while the constructions of small dams are growing everytime more. With that being said, the present work intends to analise the geological and geotechnical conditionants that can cause break of small earth dams by making a case study in the Jaguari Mirim Watershed, located in the city of São João da Boa Vista (SP), and can be used to encourage the concern with small dams. In the area of study were identificaded, from satellite images, 248 dams. The map of physiographical compartmentalization defined by Pilachevsky (2013) was used to define the locations in the study área that would have bigger risk to the break of dams. Then, 9 of this dams were analised in field research, using references made by Cerri, Reis e Giordano (2011) and the risk of the analised dams were defined. A study about this type of structure is highly necessary to avoid big damages. An analysis of the geological and geotechnical conditionants that can cause break of dams guides the project in a way to avoid adverse consequences, especially when integrated with locacional conditions observed in the place of the dam’s building

Da descrição ao ensino da oração adjetiva: a perspectiva dos livros didáticos de língua portuguesa

This paper aims at investigating the treatment given to relative clauses by elementary school text books, evidencing how the teaching of grammar is proposed in the teacher’s books. As a consequence, this study also intends to discuss important aspects to be considered as far as the teaching of relative clauses is concerned. In order to achieve that objective, five Portuguese text books (approved by the Programa Nacional do Livro Didático-2014) were selected so that the grammar teaching proposals could be analyzed in relation to the definition and to the distinguishing criteria between defining and non-defining relative clauses. Results show that the teaching of relative clauses (as proposed by the teacher’s books) still reflects the postulates of the traditional grammar, based on activities of identification and classification of morphosyntactic units, ignoring the pragmatic and prosodic aspects.
