2. Comparison of the influence of stimuli color on Steady-State Visual Evoked Potentials
IntroductionThe main idea of a traditional Steady State Visually Evoked Potentials (SSVEP)-BCI is the activation of commands through gaze control. For this purpose, the retina of the eye is excited by a stimulus at a certain frequency. Several studies have shown effects related to different kind of stimuli, frequencies, window lengths, techniques of feature

3. PROPUESTA DE EXTRACCIÓN AUTOMÁTICA DE CANDIDATOS A TÉRMINO DEL DOMINIO MÉDICO PROCESANDO INFORMACIÓN LINGÜÍSTICA. DESCRIPCIÓN Y EVALUACIÓN DE RESULTADOS
The description of a method for automatic extraction of term candidates from the medical field by applying linguistic information is presented. Lexicography, morphological and syntactic rules were used. First, the detection was performed by applying a standard dictionary that assigned the tag ´MED´ (‘MEDICAL’) to the words that could be considered term

4. HYBRID SYSTEM FOR RULE EXTRACTION APPLIED TO DIAGNOSIS OF POWER TRANSFORMERS / SISTEMA HÍBRIDO DE EXTRAÇÃO DE REGRAS APLICADO A DIAGNÓSTICO DE TRANSFORMADORES
Este trabalho tem como objetivo construir um classificador baseado em regras de inferência fuzzy, as quais são extraídas a partir de máquinas de vetor suporte (SVMs) e ajustadas com o auxílio de um algoritmo genético. O classificador construído visa a diagnosticar transformadores de potência. As SVMs são sistemas de aprendizado baseados na teoria do

5. Ação do estado e a exploração de um recurso de acesso comum, a castanha do Brasil (Bertholletia excelsa): estudo de caso na comunidade amazônica de Tres Islas, na Região de Madre de Dios, Peru / States action and exploration of a common-pool resource, the Brazil nut (Bertholletia excelsa): case community study in Tres Islas, Madre de Dios Region, Peru
There are two remarkable characteristics during mankind history: the increasing capacity of human populations, exponentially in the last 300 years, to obtain energy and information and the increase in the complexity of the organization of their societies based especially on human interdependence. Economical and political pressures to satisfy the needs of the

6. Gestão de agregados minerais : análise e subsídios para políticas públicas / Management ggregates : comparite analysis betwen Canada and Brazil and subsidies for public policies
The biophysical and social disruption caused by aggregates mining has placed it at the center of conflict scenarios, either because of advancing urbanization on the aggregates resources or because of pressures from civil society to impose restrictions on their development. The search for solutions to this problem has required of the governments a large abili

7. Rules extraction from neural networks applied to the prediction and recognition of prokaryotic promoters
Promoters are DNA sequences located upstream of the gene region and play a central role in gene expression. Computational techniques show good accuracy in gene prediction but are less successful in predicting promoters, primarily because of the high number of false positives that reflect characteristics of the promoter sequences. Many machine learning method

8. Spatial electric load forecasting using an evolutionary heuristic
A method for spatial electric load forecasting using elements from evolutionary algorithms is presented. The method uses concepts from knowledge extraction algorithms and linguistic rules' representation to characterize the preferences for land use into a spatial database. The future land use preferences in undeveloped zones in the electrical utility service

9. Uma metodologia para extração de conhecimento em séries temporais por meio da identificação de motifs e da extração de características / A methodology to extract knowledge from time series using motif identification and feature extraction
Data mining has been applied to several areas with the objective of extracting interesting and relevant knowledge from large data bases. In this scenario, machine learning provides some of the main methods employed in data mining. Symbolic learning are among the most used machine learning methods since these methods can provide models that can be interpreted

10. Visualização como suporte à extração e exploração de regras de associação / Vusualization as support to the extraction and exploration of association rules
Desde a definção do problema de obtenção de regras de associação, vários algoritmos eficientes foram introduzidos para tratá-lo. Entretanto, ainda hoje o problema apresenta várias dificuldades práticas para os mineradores, como a determinação de limiares adequados de suporte mínimo e confiança mínima, a manipulação de grandes conjuntos de re

The snooks are fishes very appreciated food item by fish consumers and recreational fishermen, for they are endowed with a high quality flesh and put up a fierce fight when captured with line-and-hook. Such characteristics make this taxon a target for a host of users, objectives and needs (commercial and recreational fishing) which, together with loss of hab
