The representation of real objects in virtual environments has applications in many areas, such as cartography, mixed reality and reverse engineering. The generation of these objects can be performed through two ways: manually, with CAD (Computer Aided Design) tools, or automatically, by means of surface reconstruction techniques. The simpler the 3D model, the easier it is to process and store it. However, this methods can generate very detailed virtual elements, that can result in some problems when processing the resulting mesh, because it has a lot of edges and polygons that have to be checked at visualization. Considering this context, it can be applied simplification algorithms to eliminate polygons from resulting mesh, without change its topology, generating a lighter mesh with less irrelevant details. The project aimed the study, implementation and comparative tests of simplification algorithms applied to meshes generated through a reconstruction pipeline based on point clouds. This work proposes the realization of the simplification step, like a complement to the pipeline developed by (ONO et al., 2012), that developed reconstruction through cloud points obtained by Microsoft Kinect, and then using Poisson algorithm

The representation of real objects in virtual environments has applications in many areas, such as cartography, mixed reality and reverse engineering. The generation of these objects can be performed in two ways: manually, with CAD (Computer Aided Design) tools, or automatically, by means of surface reconstruction techniques. The simpler the 3D model, the easier it is to process and store it. Multiresolution reconstruction methods can generate polygonal meshes in different levels of detail and, to improve the response time of a computer program, distant objects can be represented with few details, while more detailed models are used in closer objects. This work presents a new approach to multiresolution surface reconstruction, particularly interesting to noisy and low definition data, for example, point clouds captured with Kinect sensor

Communities are present on physical, chemical and biological systems and their identification is fundamental for the comprehension of the behavior of these systems. Recently, available data related to complex networks have grown exponentially, demanding more computational power. The Graphical Processing Unit (GPU) is a cost effective alternative suitable for this purpose. We investigate the convenience of this for network science by proposing a GPU based implementation of Newman community detection algorithm. We showed that the processing time of matrix multiplications of GPUs grow slower than CPUs in relation to the matrix size. It was proven, thus, that GPU processing power is a viable solution for community dentification simulation that demand high computational power. Our implementation was tested on an integrated biological network for the bacterium Escherichia coli
Violência no contexto escolar: um estudo das representações de alunos e alunas do ensino fundamental

Um dos temas mais discutidos na instituição de ensino é a problemática da violência dentro do espaço escolar. Porém sabemos que essa questão é delicada e complexa e, para o seu enfrentamento, é necessário, entre outras medidas, o conhecimento de como os jovens percebem sobre esta questão no contexto da escola. Para tanto, este trabalho buscou o prisma dos estudantes sobre o assunto. O objetivo dessa investigação foi compreender a visão de alunos e alunas, estudantes de uma escola municipal, localizada no interior do estado de São Paulo, na cidade de Botucatu, sobre as manifestações violentas (físicas, verbais, psicológicas), no âmbito escolar, as possíveis causas dessas ações, bem como suas sugestões para solucionar o problema da violência no interior das instituições educacionais. O estudo foi desenvolvido a partir de uma abordagem qualitativa de pesquisa e os dados foram coletados por meio de questionários individuais, discussões em grupo de textos jornalísticos, produção individual de desenhos e produção de cartazes em grupo. Os dados coletados e analisados revelam que as representações sobre a violência escolar mais freqüente estão relacionadas à violência física, sendo que a violência verbal e psicológica aparece com índices semelhantes e com uma freqüência muito menor que a violência física. O estudo também identifica a maneira como essas ações agressivas são identificadas e tratadas pelos alunos; quem são os envolvidos nos atos de agressão; os locais e horário de maior incidência de violência dentro da escola; qual a vivência dos participantes da pesquisa sobre a violência; e que medidas eles buscariam para solucionar essa problemática em sua escola. Conclui-se que, para a maioria dos alunos, a solução do problema da violência é necessária aplicar punições disciplinares e policiais cada vez mais radicais.

This paper aims to present the representations of the working world of high school students, the State School Prof. Dr. João Deoclécio da Silva Ramos, Distrito de Talhado, São José do Rio Preto (SP), through the use of virtual media, specifically the Blog de Aula – Mutirão de Sociologia (www.mutiraodesociologia.com.br). Understanding the representations of the world work enables students to think of a profession which identify themselves, and stimulate reflection as future professionals. The virtual media, especially blogs, allow students to express their ways of living and thinking the world of work. In the context of the city of Rio Preto, is especially relevant these representations of the world’s rural work, so this project is to collaborate in the development of research concerned with the description and understanding of processes that involve relationships between work, education and rural.

This article is devoted to a brief analysis of representations of women in As meninas, by Lygia Fagundes Telles, focusing on the three main characters of the novel and also on some secondary characters. The novel is set within a context that was characterized by a double crisis: the political crisis arising from authoritarianism and violence of the military dictatorship, and the crisis of the patriarchy system, due to the gradual political and social emancipation of women. Our paper aims to understand, in a succinct way, the critical dialogue established in the novel between the representations of women and that context of the dual crisis that constitute the novelistic material of As meninas

This paper focuses on how the ancient roman poet Ovid’s approach on the mythical character Medea in Metamorphoses Book VII relates to the presence of the character in the Hellenistic greek epic poem Argonautica of Apollonius Rhodius, once the Greek author is known to influence the Roman. Although Ovid’s narrative goes further and focuses on events subsequent to the Argonauts travel, the relationship between the two works allows to address two aspects: the inner monologue and the anxieties of Medea which, by their turn, draw a timeline of the historical influence of Euripedes’ tragedy Medea; going through Apollonius and eventually arriving at Ovid; and the description of Medea’s magical practices and powers, used in Argonautica to protect Jason, which are widely described in Metamorphoses when she rejuvenates Aeson, the hero’s father. It is intended not only to point out aspects of character related to these topics, but primarily to address the mechanisms that can identify the direct influence of Apollonius on Ovid

Dissolution representations in Chemistry textbooks: the case of PNLEM. In Chemistry education, so as in other sciences, the use of images is fundamental in the process of teaching and learning. By virtue of this, the textbooks can be a vehicle of such importance, therefore contributing with many images and representations. In this context, the present work has as objective to promote the analysis of the six books approved by the “Programa Nacional do Livro do Ensino Médio, (PNLEM)”, being the main subject of investigation, the dissolution phenomena. Although the recognized importance of opperate in the theoretical and conceptual level to understand chemistry phenomena, our results suggest the need of greater reflection concerning the emphasis attributed to this hability. And so, this paper has as purpose contributing in the reflection of the professor during the choice and use of the LDs and in the process of evaluation of the same.
