WebMar 3, 2024 · In this study, multifractal detrended fluctuation analysis (MF-DFA) was used to calculate the multifractal characteristics of acoustic emission signals. The salient feature of the method is that it makes full use of the sequence data length by dividing the acoustic emission sequences in equal length from the forward and reverse bi-directional ... The Detrended Fluctuation Analysis (DFA) has become a widely usedtechnique for detecting long range correlations in time series. The DFA procedure may be summarized as follows: 1. Integrate the time series to be analyzed. The time series resulting from the integration will be referred to as the profile. 2. … See more Functions for performing Detrended Fluctuation Analysis (DFA), a widely usedtechnique for detecting long range correlations in time series.
