Fluctuation Analysis of Human Electroencephalogram [PDF]

, 2001
The scaling behaviors of the human electroencephalogram (EEG) time series are studied using detrended fluctuation analysis. Two scaling regions are found in nearly every channel for all subjects examined. The scatter plot of the scaling exponents for all

Detrended fluctuation analysis for fractals and multifractals in higher dimensions

, 2006
One-dimensional detrended fluctuation analysis (1D DFA) and multifractal detrended fluctuation analysis (1D MF-DFA) are widely used in the scaling analysis of fractal and multifractal time series because of being accurate and easy to implement.

Task-dependent fractal patterns of information processing in working memory

Scientific Reports, 2022
We applied detrended fluctuation analysis, power spectral density, and eigenanalysis of detrended cross-correlations to investigate fMRI data representing a diurnal variation of working memory in four visual tasks: two verbal and two nonverbal.

Detrended Fluctuation analysis of Bach's Inventions and Sinfonias pitches

, 2007
Detrended Fluctuation Analysis (DFA), suitable for the analysis of nonstationary time series, is used to investigate power law in some of the Bach's pitches series. Using DFA method, which also is a well-established method for the detection of long-range

Investigating detrended fluctuation analysis with structural breaks [PDF]

Physica A: Statistical Mechanics and its Applications, 2019
Abstract Detrended Fluctuation Analysis has been used in several fields of science to study the statistical properties of trend stationary and nonstationary time-series. Its application to financial data has produced important results concerning long-range correlations and long-memory.

Scaling behavior of an artificial traffic model on scale-free networks [PDF]

, 2006
In this article, we investigate an artificial traffic model on scale-free networks. Instead of using the routing strategy of the shortest path, a generalized routing algorithm is introduced to improve the transportation throughput, which is measured by ...

Spatial–Temporal Variability of Land Surface Temperature Spatial Pattern: Multifractal Detrended Fluctuation Analysis

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
In order to investigate the spatial-temporal variability of land surface temperature (LST) spatial distribution in the context of rapid urbanization, we introduced the multifractal detrended fluctuation analysis (MFDFA) to the LST patterns in Xiamen city
