1. Avaliação de estratégias de modelagem guiada por dados para previsão de vazão em rio sergipano
Dentre as várias técnicas de previsão de vazão, os modelos guiados por dados (DDMs: data-driven models) estão sendo muito utilizados. Estes se baseiam num banco de dados formado pelos registros históricos das variáveis de entrada (precipitação e vazão) e saída (vazão) para realizar a previsão. Redes neurais artificiais (ANNs: artificial neural n

2. Seleção de componentes em ensembles de clasificadores multirrótulo / Component Selection in Ensembles of Multi-label Classifiers
The selection of components in ensembles of classifiers is a very common activity in the field of Machine Learning with several studies showing its effectiveness in obtaining significant gains in accuracy. However, the most studied classification task involves mutually exclusive labels (classes). The objective of this work is to present a study on the select

3. A descrição literária e suas construções em torno do adjetivo em frânces / The literary description and its constructions around the adjective in French
The aim of this work is to study the construction of the descriptive literary text, particularly considering the role of the adjective and its operation within this textual organization mode. In this sense, the present research is inserted in reflections around the linguistic and literary aspects. Based on the descriptive text, it is not the aim here to stud

4. 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

5. Trajetórias de apropriação de vídeos e filmes por um grupo de professores de língua inglesa
The TV and the video have already been seen as a threat to formal education, accused of spreading a world out of reality, of inducing students to submerge in a world of violence and ideology controlling, and of taking time that students could use studying. However, this point of view has been replaced as quick as the means of communication and information te

6. Conversão simbólica de sinais digitais por meio da Teoria de Extremos Relativos
The goal is to develop a new technique for symbolic conversion of digital signals, called Quantization based on Relative Extrema (QBER). This technique can convert unidimensional digital signals into strings. The technique QBER, formalized in this proposal, uses Relative Extrema Theory (TER ) and signals similarity functions, as metric Edit Distance with Rea

7. 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,

8. Contos populares compilados e discurso no curriculo da educação bilingue alemão-portugues, no Brasil / Popular tails and discourse in bilingual education german-portuguese, in Brazil
This work is based on the following premises: a) studies that focus on cultural and enunciation issues must have a constitutive place in the teaching-learning of languages; b) we consider the language curriculum to be a central and significant place for the insertion of such components. One of the paths proposed to achieve this objective is to take into cons

9. Dinamicas discursivas na aula de portugues : os usos do livro didatico e projetos didaticos autorais / Discursive dynamics in Portuguese s classes : the use of textbooks and teaching projects
The main purpose of this dissertation is to reflect on the uses of didactic books in the discursive dynamics of the Portuguese language classroom. Based on studies about the genesis and fabrication of this school discipline and of the didactic book of Portuguese (henceforth DBP), we attempt to go beyond the representation of the Portuguese language teacher a

10. DetecÃÃo de mÃdulos de software propensos a falhas atravÃs de tÃcnicas de aprendizagem de mÃquina
The success of software depends directly on its quality. Traditionally, formal methods and manual code inspection are used to assure it. Generally, such methods have a high cost and demand a lot of time. Therefore, tests should be carefully planned to avoid waste of resources. Nowadays, companies are looking for faster and cheaper ways to detect software def

11. Uma análise da aplicação do modelo de Rede Neural RePART em Comitês de classificadores
RePART (Reward/Punishment ART) is a neural model that constitutes a variation of the Fuzzy Artmap model. This network was proposed in order to minimize the inherent problems in the Artmap-based model, such as the proliferation of categories and misclassification. RePART makes use of additional mechanisms, such as an instance counting parameter, a reward/puni

12. ELES NÃO ESTÃO NEM AÍ!: IMPACTOS DA CONTEMPORANEIDADE SOBRE O ATO DE EDUCAR
This paper offers social-philosophical contributions from psychoanalysis to the discussion of contemporary impacts on schools and education. Education is done by dissymmetry, by the assumption of the absence of freedom and by the valorization of the social tie, the collectivity. The act of educating, in that way, walks against the values of the society of co
