... resolution lead to a reduction of a 30% of life expectancy of a method is unknown, where the classic algorithms are capacitor [7]. Because sampling frequency necessary for ineffective, or where it is very expensive to apply due to its obtaining a valid signal for the power quality analysis is by the range of ...

... When connected to an excitation source, there will be an energy transfer from the coil to the wire. The maximum energy transfer will occur at the vibrating wire's frequency of resonance. Using the transient regime analysis, it has been proven that, in the response time interval €“ when the wire vibrates freely, the current ...

... become parameterization was performed with the use of the spectral subband centroid energy vectors (SSCEV) algorithm, which consistent when performed with the use of intelligent compresses the frequency spectrum and presents the results of systems capable of recognizing data patterns and classifying the AE energies in several frequency bands. Thus, it was them adequately [ ...
