1. Utilização de redes neurais artificiais no diagnóstico de cardiopatias
This work is about the application of Artificial Neural Networks for the diagnosis of heart disease as arrhythmia and insufficience heart congestive. The followed steps had been: Acquisition and conditioning of the data to be applied as input of the nets; Training of several nets to choose that with the best performance. The neural network to diagnosis healt

2. Identificação de bovinos através de reconhecimento de padrões do espelho nasal utilizando redes neurais artificiais / Identification of bovines through recognition of images patterns of the muzzle using artificial neural nets
Artificial Neural Networks (ANN) are mathematical models associated with artificial intelligence that can learn and generalize information, therefore they can be used as images classifiers. This paper aims to analyze the cattle muzzle in order to prove that it is a unique and permanent characteristic of the animal thus, being used as its unique identificatio

3. Um estudo sobre processamento adaptativo de sinais utilizando redes neurais / A study about adaptive signal processing using neural nets
Nos últimos anos muito tem se pesquisado na área de arquiteturas paralelas de computadores, devido ao fato da melhora de desempenho nas arquiteturas sequenciais não estar acompanhando as necessidades crescentes de capacidade de processamento. Entre as arquiteturas paralelas, um grupo que tem recebido especial atenção por parte dos pesquisadores é o de

4. Reconhecimento semântico através de redes neurais artificiais / Semantic recognition through artificial neural nets
Um dos grandes desafios atuais da computação e ultrapassar o abismo existente entre o homem e a maquina. Para tanto, o desafio passa a ser a formalização de estados mentais e sua modelagem computacional. Isso e necessário, uma vez que o homem somente conseguira comunicar-se com uma maquina quando esta puder dar e receber informações sem que o homem pr

5. Ensaios de ondas ultrassônicas e redes neurais artificiais na avaliação da resistência à compressão do concreto
Stripping of formworks in reinforced concrete structures can only be done when concrete is hardened enough to carry the loads without generating unacceptable deformations. These are two important demands from Brazilian Code NBR 14931-2004. To get those conditions the structural design engineer should inform the building engineer the minimum values of compres

6. Linguagens de domínio específico e sensores baseados em modelos biológicos de computação
A Domain Specific Language is a specification language dedicated to a particular domain, representation technique, or solution searching method. On the other hand, a general-purpose programming language is a language designed with the goal of emulating Lambda Calculus or Turing Machine. Since general-purpose languages must accept any algorithm that can be ex

7. Estudo de equilÃbrio de troca iÃnica de sistemas binÃrios e ternÃrios por meio de redes neurais / Ion exchange equilibrium of the binary and ternary systems using neural network and mass action law
In the majority of the applications of the process of ionic exchange in the chemical industry some ionic species are gifts that compete between itself for the active small sieges of the ionic exchanger. Therefore, the project of these systems requires an analysis of the coefficients of selectivity of ions gifts in the solution that determines the influence o

8. Análise do padrão cinemático da marcha em equinos por meio de redes neurais artificiais
A total of 39 adult horses (29 male and 10 female), gait champions and reserved champions of Campolina, Mangalarga, Mangalarga Marchador and Pampa breeds at national expositions, were analyzed by the experiment described in chapter II. For characterization of the gait pattern of the different breeds, 8 different joint angles, obtained by video film digitaliz

9. 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

10. Nova metodologia para análise e síntese de sistemas de aterramento complexos utilizando o método lN-FDTD, computação paralela automática e redes neurais artificiais / New methodology for analysis and synthesis of complex systems of aterramento using method LN-FDTD, automatic parallel computation and artificial neural nets
Neste trabalho, o método FDTD em coordenadas gerais (LN-FDTD) foi implementado para a análise de estruturas de aterramento com geometrias coincidentes ou não com o sistema de coordenadas cartesiano. O método soluciona as equações de Maxwell no domínio do tempo, permitindo a obtenção de dados a respeito da resposta transitória e de regime estacioná

11. Avaliação das perdas e dos fatores bioclimáticos atuantes na condição de espera pré-abate de frangos de corte / Evaluation of losses and bioclimatic factors present on poultry preslaughter lairage condiction
Nowadays, Brazilian poultry industry has a challenge of reducing losses. However, the disinformation about the critical points limits this advance, mainly on preslaughter operations. Therefore, studies must be carried through diagnosing scenes and identifying the critical points, which is found the biggest losses. Therefore, the objective of this work was to
