Scaling and memory in the return intervals of energy dissipation rate in three-dimensional fully developed turbulence

, 2008
We study the statistical properties of return intervals $r$ between successive energy dissipation rates above a certain threshold $Q$ in three-dimensional fully developed turbulence.

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

Fractal 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

Jixie 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 ...

Distribution of Air Temperature Multifractal Characteristics Over Greece

Atmosphere, 2019
In this study, Multifractal Detrended Fluctuation Analysis (MF-DFA) is applied to daily temperature time series (mean, maximum and minimum values) from 22 Greek meteorological stations with the purpose of examining firstly their scaling behavior and then

Multifractal Fluctuations in Seismic Interspike Series

, 2005
Multifractal fluctuations in the time dynamics of seismicity data have been analyzed. We investigated the interspike intervals (times between successive earthquakes) of one of the most seismically active areas of central Italy by using the Multifractal ...

Fractal Markets Hypothesis and the Global Financial Crisis: Scaling, Investment Horizons and Liquidity

, 2012
We investigate whether fractal markets hypothesis and its focus on liquidity and invest- ment horizons give reasonable predictions about dynamics of the financial markets during the turbulences such as the Global Financial Crisis of late 2000s.
