Název v původním jazyce

Material micro-defect classification in acoustic emission framework

Popis výsledku v původním jazyce

We compared a number of viable classification methods from which the DS method stands out both in its theoretical and practical convenience. First, the amount of data received from the measuring system is reduced by setting a set of empirical scalar parameters for each signal sampled digitally at 4MHz frequency by the measurement device Dakel Xedo 5. We can say that we seek for the efficient and relatively low dimensional vector representation of the signal. The characteristic parameter attributes are calculated both from the signals and from the signal's normalized spectra Zf, as an example we mention here Spectral beta-quantile.
