Multifractal variability in geoelectrical signals and correlations with seismicity: a study case in southern Italy [PDF]

Natural Hazards and Earth System Sciences, 2005
Multifractal fluctuations in the time dynamics of geoelectrical data, recorded in a seismic area of southern Italy, have been revealed using the Multifractal Detrended Fluctuation Analysis (MF-DFA), which allows to detect multifractality in nonstationary

Integrating Multifractal Features into Machine Learning for Improved Prediction

Fractal and Fractional
This study investigates the multifractal characteristics of the tanker freight market from 1998 to 2024. Using multifractal detrended fluctuation analysis (MF-DFA) and multifractal detrending moving average (MF-DMA), we analyze temporal correlations and ...

Heart rate variability series during physical activity analyzed with multifractal techniques

Journal of Physics: Complexity
Our study uses multifractal techniques to analyze time series of heart rate variability series ( RR time series) during rest and physical activity. Subsets of the RR time series data were extracted for each stage.
