13. Sobre o problema da identidade pessoal: David Hume e seus críticos
On the problem of personal identity: David Hume and his critics the problem of personal identity is, perhaps, the most polemic topic of David Hume s (1711-1776) philosophy. Three causes can be pointed: the innovation of Hume s explanation when he defines the mind as a bundle of perceptions that lacks perfect identity; the confession, in "Appendix", of dissat

14. Semi-supervised learning based in disagreement by similarity / Classificação semi-supervisionada baseada em desacordo por similaridade
Semi-supervised learning is a machine learning paradigm in which the induced hypothesis is improved by taking advantage of unlabeled data. Semi-supervised learning is particularly useful when labeled data is scarce and difficult to obtain. In this context, the Cotraining algorithm was proposed. Cotraining is a widely used semisupervised approach that assumes

15. Hardware/Software codesign of particle filter for real time localization of mobile robots / Co-projeto de hardware/software do filtro de partículas para localização em tempo real de robôs móveis
Sophisticated techniques for estimation of models based on simulation, particle filters or Sequential Monte Carlo Methods, were recently used to solve many difficult problems in the field of mobile robotics. However, the success of particle filters was limited to the computation of parameters in low dimensionality spaces. The current research efforts in mobi

16. TEACHER AS A MAKER OF CURRICULUM: CHALLENGES IN THE SUPERVISED CURRICULAR TRAINING IN PHYSICS TEACHING / PROFESSOR FAZEDOR DE CURRÍCULOS: DESAFIOS NO ESTÁGIO CURRICULAR SUPERVISIONADO EM ENSINO DE FÍSICA
In the face of current educational problems, indicated by research, as the propedeutic education and the separation between the "world of life" and the "world of school," the conception of science and technology neutral, among others, it is necessary to "make changes" in curriculum. Moreover, it is argued that teachers should be part of the process of curric

17. Avaliação técnica e econômica para aproveitamento da biomassa caprina em biodigestores no Semi-Árido Baiano.
The exhaustion of some fossil energy sources, caused by the increasing demand in the last years, as well as the worldwide consciousness about the environment issues, has brought a continuous quest for new sustainable means of production. In this new context, the biogas technology represents a real possibility of generating clean energy and, at the same time,

18. Classificação multi-rótulo hierárquica de documentos textuais
The amount of information stored in text databases is steadily increasing. As such, demand for automated techniques to organize this data also continues to grow. In this context, academic and industry research has been focused on the study of automatic text classification. Most work on text classification studies the development of techniques in which there

19. Técnicas de aumento de eficiência para metaheurísticas aplicadas a otimização global contínua e discreta / Efficiency--enhancement techniques for metaheuristics applied and continuous global optimization
Several real-world problems from various fields of Science and Engineering can be modeled as global optimization problems. In general, complex and large-scale problems can not be solved eficiently by exact techniques. In this context, Probabilistic algorithms, such as metaheuristics, have shown relevant results. Nevertheless, as the complexity of the problem

20. Classifiers and machine learning techniques for image processing and computer vision / Classificadores e aprendizado em processamento de imagens e visão computacional
In this work, we propose the use of classifiers and machine learning techniques to extract useful information from data sets (e.g., images) to solve important problems in Image Processing and Computer Vision. We are particularly interested in: two and multi-class image categorization, hidden messages detection, discrimination among natural and forged images,

21. Rompendo o contrato didÃtico: a utilizaÃÃo de estratÃgias metacognitivas na resoluÃÃo de problemas algÃbricos
This study aimed to analyse the relationship between didactic contract and metacognition in the resolution of algebraical problems. For that, we had the collaboration of a Mathematics teacher and his 8th grade students of a private school in Recife. The methodology was divided in four steps, including classroom observations and meetings with the teacher, all

22. Escola, lugar e poder: as aventuras de um professor-pesquisador entre o subúrbio e a periferia / School, place and power: the adventures of a professor-researcher between suburb and periphery
The present work has as objective understands the different forms that takes over the relationship among school, communitys place and power in the paulistan suburbs and outskirts. For this were studied two schools placed in metropolitan region of São Paulo (one in São Caetano do Sul, other in Itaquera district, east zone of São Paulo.), looking for descri

23. Investigando as ações de problematização no processo de projeto de arquitetura
The design situation starts with what Donald A. Schön (1983) calls the problematic situation: a real situation in which there is need for changing, and which is characterized by uncertainty, complexity and indetermination. The design activity is developed in this context in such a way that its final product establishes the framework of the changing plan for

24. Collaborative problem based - ACBP : conceptual model and tolls / Aprendizagem colaborativa baseada em problemas - ACBP : modelo conceitual e ferramentas
This research presents the model entitled Collaborative Problem Based Learning (ACBP), which was conceived through the compilation and analyses of structural and functional characteristics of Problem Based Learning and Computer Supported Collaborative Learning. The model s basis is composed of the discussions and reflection of a small student group as they i
