Detrended Fluctuation Analysis of uterine electromyography
2011 1st Middle East Conference on Biomedical Engineering, 2011In respect to the main goal of our ongoing work for predicting preterm birth, we analyze in this paper uterine EMG recordings of 11 pregnant and laboring women by means of Detrended Fluctuation Analysis (DFA), a scaling analysis method that quantifies a simple parameter to represent the correlation properties of a time series.

Detrended Fluctuation Analysis of EEG as a Measure of Depth of Anesthesia
IEEE Transactions on Biomedical Engineering, 2007For several decades, a number of methods have been developed for the noninvasive assessment of the level of consciousness during general anesthesia. In this paper, detrended fluctuation analysis is used to study the scaling behavior of the electroencephalogram as a measure of the level of consciousness.

Effects of quantization on detrended fluctuation analysis
Chinese Physics B, 2011Detrended fluctuation analysis (DFA) is a method foro estimating the long-range power-law correlation exponent in noisy signals. It has been used successfully in many different fields, especially in the research of physiological signals. As an inherent part of these studies, quantization of continuous signals is inevitable. In addition, coarse-graining,

Detrended fluctuation analysis of repetitive handwriting
2017 International Conference on Noise and Fluctuations (ICNF), 2017Although there is a tendency that the opportunity to write by hand is decreasing, handwriting is still one of the everyday activities of our lives. In this study, the experimental system that limits the writing speed of a subject was set up. The aim was to measure the fluctuation time series of a time element obtained from the measurement performed ...

Detrended Fluctuation Analysis of Traffic Data
Chinese Physics Letters, 2007Different routing strategies may result in different behaviour of traffic on internet. We analyse the correlation of traffic data for three typical routing strategies by the detrended fluctuation analysis (DFA) and find that the degree of correlation of the data can be divided into three regions, i.e. weak, medium, and strong correlation.

Detrended Fluctuation Analysis of EEG in Depression
2014Diagnosis of depression is still based mainly on evaluation of the intensity of subjective and clinical symptoms by psychiatrists. This study is aimed to give additional objective information about depression analyzing the electroencephalographic (EEG) signal using the method of detrended fluctuation analysis (DFA).

Applications of Multifractal Detrended Fluctuation Analysis
Journal of Information and Computing ScienceIn recent years, multifractal detrended fluctuation analysis (MF-DFA) has become an important tool for detecting the scale and long correlation of non-stationary time series. With the continuous development of multifractal theory, researchers have widely applied it in physics, chemistry, biology, economy, etc.

A NOVEL CORRELATION FUNCTION FROM DETRENDED FLUCTUATION ANALYSIS
Modern Physics Letters B, 2005A method for investigating the existence of long-range correlations between two sequences is proposed from the detrended fluctuation analysis method. A new correlation function is defined and its behavior is shown for simple examples.
