1. Dexterous hand gestures recognition based on low-density sEMG signals for upper-limb forearm amputees
Abstract Introduction Intuitive prosthesis control is one of the most important challenges in order to reduce the user effort in learning how to use an artificial hand. This work presents the development of a novel method for pattern recognition of sEMG signals able to discriminate, in a very accurate way, dexterous hand and fingers movements using a reduce

2. Reconhecimento de PadrÃes AtravÃs de AnÃlises EstatÃsticas e Fractais Aplicadas a Dados de Ensaios NÃo-Destrutivos / Pattern Recognition by Statistical Fluctuation and Fractal Analyses Applied to Nondestructive Testing Data
In this work a procedure is studied for pattern classification related to different types of data, namely: (1) signals obtained from ultrasonic testing ( pulse-echo technique) and magnetic signals obtained from BarkhÃusen noise in samples of ferritic-pearlitic carbon steel tubes which, due to temperature effects, have shown microstructural changes as conseq

3. Determinantes individuais: fatores predisponentes à utilização dos serviços de saúde na atenção ao diagnóstico da tuberculose / Individual determinants: predisposing factors to the utilization of health services in the attention to tuberculosis diagnostic.
The delay in diagnosing Tuberculosis (TB) has been used to reflect the quality and opportunity of access by patients to the health care. Among many aspects which must be incorporated to evaluate the access, the present study aims to identify the influence of individual determinants about the pattern of service utilization in the attention to TB diagnostic, s

4. Sistema de reconhecimento de padrÃes para identificaÃÃo de porte de veÃculos atravÃs de anÃlise de perfil magnÃtico / A Pattern recognition system for identification of vehicles by analysis of magnetic profile
Currently, transit agencies use traffic monitoring systems to reduce traffic accidents and as a fundamental tool for collecting statistical data for planning and management of road systems. These data are observed as the amount of information vehicles that travel at a certain point, the average speed and the identification of the category of vehicles. The id

5. Um estudo sobre reconhecimento de padrões: um aprendizado supervisionado com classificador bayesiano / A study on pattern recognition: supervised learning with a Bayesian classier
The facility we have to recognize a face, to understand spoken words, reading manuscripts, identifying car keys in our pocket and deciding whether an apple is ripe by its smell, belie the complex processes that are behind the act to recognize these patterns. These recognitions have been crucial to our survival, and over the past tens of millions of years sop

6. Análise estatística multivariada para reconhecimento de padrões em ensaios não destrutivos magnéticos. / Multivariate statistical analysis for pattern recognition applied to a non destructive magnetics testing.
Neste trabalho se estuda a aplicação de técnicas de estatística multivariada para reconhecimento de padrões em sinais de ensaios não destrutivos (END) magnéticos, baseados no Ruído Magnético de Barkhausen (RMB). O reconhecimento de padrões pode ser feito de forma não supervisionada com a técnica multivariada de Análise de Agrupamentos, conglomer

7. Reconhecimento de padrões em imagens por descritores de forma / Pattern recognition in images via shape descriptors
A idéia de capacitar uma máquina a reconhecer o ambiente em que atua tem motivado pesquisadores a investir esforços no estudo do mais complexo dos sentidos humanos, a visão. A visão é, antes de tudo, uma tarefa de representação e processamento de informações, sendo portanto adequada ao tratamento computacional. Visto que ainda não se possuem méto

8. Aplicação da Lógica Fuzzy kNN e análises estatísticas para seleção de características e classificação de abelhas. / Application of Fuzzy kNN and statistical analysis for features selection and classification of bees.
Este trabalho propõe uma alternativa para o problema de classificação de espécies de abelhas a partir da implementação de um algoritmo com base na Morfométria Geométrica e estudo das Formas dos marcos anatômicos das imagens obtidas pelas asas das abelhas. O algoritmo implementado para este propósito se baseia no algoritmo dos k-Vizinho mais Próxim

9. Padrões florísticos e estruturais das Florestas Estacionais Semideciduais do Triângulo Mineiro, MG / Floristic and structural patterns of semideciduous seasonal forests of Triângulo Mineiro, MG
The semideciduous seasonal forests (SSF) of southeastern Brazil have a high floristic diversity, accompanied by a high beta diversity, even between nearby fragments. However, nowdays these forests have been represented by a large number of small fragments, a landscape pattern typical for this region. In addition to the processes related to fragmentation, the

10. System board to measures of gas-liquid two-phase flow / Sistema embarcado para medidas de escoamento bifasico gas-liquido
Two-phase flow gas-liquid are commonly found in nature and in various industrial activities. In this type of flow, the phases present can escape arranged in different spatial configurations in the duct, called regimes or flow patterns, the determination is critical for the design of two-phase flow systems. In this study, an indication of the flow pattern is
