Directional Variations in Tidal Flow Multifractality and Intermittency

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract We explored distinct directional variations of multifractal and intermittent characteristics of ebb and flood flow velocities at nodule point, WA, tidal energy site, and complementary inspection on the East River, NY using scaling exponents of the structure function, distribution flatness, detrending moving average (DMA) analysis, multifractal

Joint multiscale dynamics in soil–vegetation–atmosphere systems: Multifractal cross‐correlation analysis of arid and semiarid rangelands

open access: yesVadose Zone Journal, Volume 24, Issue 1, January/February 2025.
Abstract Understanding the dynamics of the soil–vegetation–atmosphere (SVA) system, particularly in arid and semiarid regions, remains challenging due to its intricate and interdependent nature. This system creates problems for rangeland administration, such as insurance and risk management. This paper focuses on the complex interactions within the SVA

Modified detrended fluctuation analysis based on empirical mode decomposition

open access: yes, 2009
Detrended fluctuation analysis (DFA) is a simple but very efficient method for investigating the power-law long-term correlations of non-stationary time series, in which a detrending step is necessary to obtain the local fluctuations at different ...

Robust Fractional Low‐Order Multiple Window STFT for Infinite Variance Process Environment

open access: yesIET Signal Processing, Volume 2024, Issue 1, 2024.
Mechanical fault vibration signal is a typical non‐Gaussian process, they can be characterized by the infinite variance process, and the noise within these signals may also be the process in complex environments. The performance of the traditional cross‐term reduction algorithm is compromised, sometimes yielding incorrect results under the infinite ...
