Observador Adaptativo Estável Usando Redes Neurais Artificiais

In this paper, an adaptive observer for multivariable nonlinear systems that present an unknown general state equation and known linear output equation is developed. The observer is based on linearly parameterized neural networks and Lyapunov methods are used for stability analysis. We consider a more general class of systems than in previous works and the usual SPR (strictly positive real) ass...

Triagem virtual de imagens de imuno-histoquímica usando redes neurais artificiais e espectro de padrões

The importance of organizing medical images according to their nature, application and relevance is increasing. Furhermore, a previous selection of medical images can be useful to accelerate the task of analysis by pathologists. Herein this work we propose an image classifier to integrate a CBIR (Content-Based Image Retrieval) selection system. This classifier is based on pattern spectra and ne...

Projeto otimizado de redes neurais artificiais para predição da rugosidade em processos de usinagem com a utilização da metodologia de projeto de experimentos

The present work offers some contributions to the area of surface roughness modeling by Artificial Neural Networks in machining processes. It proposes a method for the project of networks of MLP (Multi-Layer Perceptron) and RBF (Radial Basis Function) architectures optimized for prediction of Average Surface Roughness (Ra). The method is expressed in the format of an algorithm employing two tec...

Redes neurais aplicadas em processos de usinagem da madeira

In order to obtain products and services to exceed the level of productivity required by the market, many machining wood factors should be optimized. The current goal of research in Artificial Intelligence is dedicated to develop intelligent flexible systems, self-adjusting, to decrease the presence of human operators. The control of these processes is done through the help of computer systems ...
