1. Tunnel vision in current chemicals management cannot deal with the unknown risk of synthetic chemicals in aquatic systems
Resumo A gestão e o manejo de poluentes químicos são focados na periculosidade, exposição e avaliação de risco. Esse processo é lento e não acompanha o surgimento de novas substâncias e o desenvolvimento do seu uso. O monitoramento ambiental foca em poucas substâncias que são bem conhecidas. Consequentemente, a maioria das substâncias emitidas

2. Video segmentation based on motion coherence of particles in a video sequence
This work describes an approach for object-oriented video segmentation based on motion coherence. Using a tracking process based on adaptively sampled points (namely, particles), 2-D motion patterns are identified with an ensemble clustering approach. Particles are clustered to obtain a pixel-wise segmentation in space and time domains. The segmentation resu

3. Caminhadas determinísticas em redes complexas aplicadas em visão computacional / Determinist walks on complex applied in computer vision
Complex networks have received a growing interest in several areas of knowledge. This growth is mainly due to its flexibility in modeling and simulating topological structures that appear in our daily life. In most cases, complex networks characterization are based on basic measurements such as average degree, hierarchical degree, clustering coefficient, amo

4. Um estudo sobre a pobreza multidimensional na Região Nordeste do Brasil
The poverty is very complex to be restricted to the income insufficiency. This is a multidimensional problem that if express in terms of deficiency of basic capabilities and unmet human needs. Therefore, this work has for objective to study the poverty in the Northeast region of Brazil being considered multidimensional aspects of privation. Thus, it is initi

5. A Methodology for Surface Reconstruction from Structured Light / A Methodology for Surface Reconstruction from Structured Light / Uma Metodologia para Reconstrução de Superfícies a Partir de Luz Estruturada / Uma Metodologia para Reconstrução de Superfícies a Partir de Luz Estruturada
The surfaces reconstruction from two-dimensional images is a problem present in various areas of knowledge, such as reconstruction of organs or parts of the human body from tomography; automatic recognition of characters; computer vision for assembly and inspection, processing of aerial and satellite images for weather forecast, among others. In all these ca

6. Modelagem de percepção de humanos virtuais baseada em dados geométricos e ray-casting
Este trabalho apresenta um modelo de percepção de dados não visíveis (por exemplo, olfativas e auditivas) para humanos virtuais baseado em informações puramente geométricas existentes em ambientes virtuais. Esta proposta procurou contextualizar vários tópicos de pesquisa no que diz respeito a agentes autônomos em ambientes virtuais e suas capacidad

7. Algoritmo de vergencia para o controle de atenção de humanos virtuais
Common research problems treated in literature about Virtual Humans are most related with insertion and representation of these graphic agents in computers. With techological advance and new researches in Computer Graphics and Virtual Reality, new problems can have place, related to the funcionality of the virtual agents. Currently, one of the main challenge

8. UM MÉTODO PARA ELICITAÇÃO E MODELAGEM DE REQUISITOS BASEADO EM OBJETIVOS / A METHOD FOR ELICITATION AND MODELING OF REQUIREMENTS BASED IN OBJECTIVES
This work proposes an integration of the approach CREWS Lecritoire based on scenarios with the approach of use cases described by Regnell &al and the Method GBRAM. In this case, the work of Regnell is extended with the notion of Requirement Chunk (RC), strategies for discovering objectives through the relationships AND, OR, and refinement between RCs, as wel

9. SCENE TRACKING WITH AUTOMATIC CAMERA CALIBRATION / ACOMPANHAMENTO DE CENAS COM CALIBRAÇÃO AUTOMÁTICA DE CÂMERAS
In the television casting of sports events, it has become very common to insert synthetic elements to the images in real time, such as adds, marks on the field, etc. Usually, this insertion is made using special cameras, previously calibrated and provided with features that record their movements and parameter changes. With such information, inserting new ob

10. Prospects for total synthesis: A vision for a totally synthetic vaccine targeting epithelial tumors
Vaccines derived from totally synthetic carbohydrate antigens have been shown to elicit an immune response in both preclinical and clinical settings. The vaccines have been proven safe when administered in human clinical trials and are also competent at inducing antibodies that react with aberrant cells expressing the corresponding carbohydrate antigen.
