Detection of Gate Valve Leaks through the Analysis Fractal Characteristics of Acoustic Signal

open access: yesFractal and Fractional
This paper considers the possibility of using monofractal and multifractal analysis of acoustic signals to detect water leaks through gate valves. Detrended fluctuation analysis (DFA) and multifractal detrended fluctuation analysis (MF-DFA) were used ...

Fault Diagnosis of Gearbox based on Multifractal Detrended Cross- correlation Analysis

open access: yesJixie chuandong, 2016
The multifractal detrended fluctuation analysis( MFDFA) is developed only for processing one- dimension time series. Consequently,when applied to analyze complex vibration data from a defective gearbox,the MFDFA frequently produces poor results due to ...
