1. TRANFORMADA WAVELET E REDES NEURAIS ARTIFICIAIS NA ANÁLISE DE SINAIS RELACIONADOS À QUALIDADE DA ENERGIA ELÉTRICA / WAVELET TRANSFORM AND ARTIFICIAL NEURAL NETWORKS IN POWER QUALITY SIGNAL ANALYSIS
This work presents a different method for power quality signal classification using the principal components analysis (PCA) associated to the wavelet transform (WT). The standard deviation of the detail coefficients and the average of the approximation coefficients from WT are combined to extract discriminated characteristics from the disturbances. The PCA w

2. Tool wear monitoring in the milling process by acoustic emission / Monitoramento do desgaste de ferramenta no processo de fresamento via emissÃo acÃstica
The main goal of this work is the development of techniques for application of acoustic emission signal in tool wear monitoring in face milling operation. In this work a Sensis (DM 42) equipment for acquisition of the acoustic emission signal was used during the milling of a high strength low alloy steel (Din 38MnS6). A milling cutter with 125 mm diameter fo

3. Comparing arquitecture of neural networks for pattern ecognation system on artificial noses / ComparaÃÃo de arquiteturas de redes neurais para sistemas de reconhecimento de padrÃes em narizes artificiais
Um nariz artificial à um sistema modular composto de duas partes principais: um sistema sensor, formado de elementos que detectam odores e um sistema de reconhecimento de padrÃes que classifica os odores detectados. Redes neurais artificiais tÃm sido utilizadas como sistema de reconhecimento de padrÃes para narizes artificiais e vÃm apresentando resulta

4. Automatic fault detection in spark engine using neural network / Detecção automática de falhas em motores de combustão interna utilizando rede neural
This work presents the implementation of an automatic diagnosis tool of some faults founded in spark engine. Firstly, a cinematic study of the fault generating mechanisms is presented, and a partially modal analysis of an engine is illustrated, objectifying to provide information on how the vibratory energy spreads of these mechanisms to the sensor that capt
