5. Data mining in large sets of complex data / Mineração de dados em grande conjuntos de dados complexos
Due to the increasing amount and complexity of the data stored in the enterprises\ databases, the task of knowledge discovery is nowadays vital to support strategic decisions. However, the mining techniques used in the process usually have high computational costs that come from the need to explore several alternative solutions, in different combinations, to

6. On the classification of classes with nearly equal spectral response in remote sensing hyperspectral image data
It is well known that high-dimensional image data allows for the separation of classes that are spectrally very similar, i.e., possess nearly equal first-order statistics, provided that their second-order statistics differ significantly. The aim of this study is to contribute to a better understanding, from a more geometrically oriented point of view, of the

7. Seleção de características por meio de algoritmos genéticos para aprimoramento de rankings e de modelos de classificação / Feature selection by genetic algorithms to improve ranking and classification models
Content-based image retrieval (CBIR) and classification systems rely on feature vectors extracted from images considering specific visual criteria. It is common that the size of a feature vector is of the order of hundreds of elements. When the size (dimensionality) of the feature vector is increased, a higher degree of redundancy and irrelevancy can be obse

8. The use of Wavelet packet transform and artificial neural networks in analysis and classification of dysphonic voices
This paper presents a dysphonic voice classification system using the wavelet packet transform and the best basis algorithm (BBA) as dimensionality reductor and 06 artificial neural networks (ANN) acting as specialist systems. Each ANN was a 03-layer multilayer perceptron with 64 input nodes, 01 output node and in the intermediary layer the number of neurons

9. 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

10. Methods for truck dispatching in open-pit mining.
Material transportation is one of the most important aspects of open-pit mine operations. The problem usually involves a truck dispatching system in which decisions on truck assignments and destinations are taken in real-time. Due to its significance, several decision systems for this problem have been developed in the last few years, improving productivity

11. O jogo de futebol : investigação de sua estrutura, de seus modelos e da inteligencia de jogo, do ponto de vista da complexidade / The soccer game ; : searche of this structure, its models and intelligence of the game from the point of view of complexity
In high-level sports, small things make difference between the first and second positions. The game, and in this is case the soccer game, is a complex phenomenon where the player s performance is transdimensional. At every time players and teams meet problem-situations, in unpredictable circumstances that need fast technical, tactical, physical and psycholog
