25. Construindo ontologias a partir de recursos existentes: uma prova de conceito no domínio da educação. / Building ontologies from existent resources: a proof of concept in education domain.
In ancient Greece, Aristotle (384-322 BCE) endeavored to collect all the existing science in his world to create the Encyclopedia. In the last decade, Berners-Lee and collaborators idealized the Web as a structured repository, observing an organization they called Semantic Web. Usually, domain knowledge is organized in ontologies. As a consequence, a great n

26. RepresentaÃÃes sociais de ciclos de aprendizagem por professores da rede municipal de ensino do Recife
This research aims to analyze social representations of learning cycles of teachers from municipal teaching system of Recife. This study is theoretically based on researches related to school organization in cycles and on social representations theory, started by Serge Moscovici. Learning cycles are conceived based on a conception of inclusive school, which

27. 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,

28. Desenvolvimento e avaliação de estratégias de assistência à pilotagem para aeronaves leves
The following work presents the process of choice and development of a series of strategies to facilitate piloting on light aircrafts. These strategies are based on trajectory control instead of attitude control like it is usually done in conventional aircrafts, aiming smaller learning times as well as reduction in pilot workload, such that flight safety is

29. The other dialogue: understanding internal dialogue / O outro diálogo: uma compreensão do diálogo interno
This thesis aims to enable a wider comprehension on thought operation as well as suggest alternatives for the formation of reflexive, critical, autonomous and creative individuals. The research defends the idea that it is possible for an individual to develop vigilant attention that makes thought flexibilization and change in the course of action, possible.

30. A machine learning approach to automatic music genre classification
This paper presents a non-conventional approach for the automatic music genre classification problem. The proposed approach uses multiple feature vectors and a pattern recognition ensemble approach, according to space and time decomposition schemes. Despite being music genre classification a multi-class problem, we accomplish the task using a set of binary c

31. A INTERAÇÃO ENTRE OS CONHECIMENTOS IMPLÍCITO E EXPLÍCITO NA APRENDIZAGEM DA SEGUNDA LÍNGUA
One of the main questions towards the second language acquisition theories by the late learners is about how the process of language is done. Some researchers say that in one hand, the L1 learning is implicit, as in automatic, and on the other hand, L2 learning is characterized for being explicit and the learner develops their own strategies in order to solv

32. VisionDraughts - um sistema de aprendizagem de jogos de damas baseado em redes neurais, diferenças temporais, algoritmos eficientes de busca em árvores e informações perfeitas contidas em bases de dados
O objetivo deste trabalho é propor um sistema de aprendizagem de damas, Vision-Draughts, baseado nos trabalhos de Neto e Julia (LS-Draughts) e de Mark Lynch (NeuroDraughts). O NeuroDraughts é um bom jogador automático de damas que utiliza a técnica de aprendizagem por diferenças temporais para ajustar os pesos de uma rede neural artificial multi-camadas

33. Busca e recuperaÃÃo de componentes de software utilizando agrupamento de componentes
The development of software with reuse is an approach that can be used to achieve two main benefits: (1) increase in productivity of software projects and (2) improvements in the final quality of the products. The software reuse approach can be instantiated through the strategy of development based in software components. According to this strategy, large so

34. School repetition in parentsand studentsopinion: a study on the cycles and the continuous progression in São Paulo City Public School. / Reprovação escolar na opinião de pais e alunos: um estudo sobre os ciclos e a progressão continuada na rede municipal de ensino de São Paulo.
This thesis presents the data, analyses and interpretations of a research about on parentsand studentsconception about the organization of teaching in cycles and continuous progression. The research problem was built starting from the knowledge of the opposition of most parents and students to non-annual repetition politics, and the perception that the accom

35. Design multi-dispositivo em contextos de uso alternado e migração de tarefas / Multi-device design in contexts of interchange and task migration
With the miniaturization of digital components and the vast technological development of the past years, society has remarked the redefinition of "personal computers" by the advent of modern mobile devices. Besides the innovation, these handhelds also introduced the challenge to develop multi-device interfaces for today s desktop applications. While some cre

36. Utilização de máquinas de suporte vetorial para predição de estruturas terciárias de proteínas / Support vector machine for tertiary structure prediction
The three-dimensional structure of a protein is directly related to its function. Many projects of genetic sequence analysis accumulate a great number of protein sequences whose primary and secondary structures are known. However, the information on its three-dimensional structures are available only for a small fraction of these proteins. This fact evidence
