Multifractal Analysis of Hydrologic Data Using Wavelet Methods and Fluctuation Analysis

Discrete Dynamics in Nature and Society, 2017
We study the multifractal properties of water level with a high-frequency and massive time series using wavelet methods (estimation of Hurst exponents, multiscale diagram, and wavelet leaders for multifractal analysis (WLMF)) and multifractal detrended ...

Toward Interactions through Information in a Multifractal Paradigm

Entropy, 2020
In a multifractal paradigm of motion, Shannon’s information functionality of a minimization principle induces multifractal–type Newtonian behaviors. The analysis of these behaviors through motion geodesics shows the fact that the center of the Newtonian ...

On Measures Resisting Multifractal Analysis [PDF]

, 2015
Any ergodic measure of a smooth map on a compact manifold has a multifractal spectrum with one point - the dimension of the measure itself - at the diagonal. We will construct examples where this fails in the most drastic way for invariant measures invariant under linear maps of the circle.

Multifractal Analysis of the Structure of Organic and Inorganic Shale Pores Using Nuclear Magnetic Resonance (NMR) Measurement

Journal of Marine Science and Engineering, 2023
The multifractal structure of shale pores significantly affects the occurrence of fluids and the permeability of shale reservoirs. However, there are few studies on the multifractal characteristics of shale pores that distinguish between organic and ...

Multifractal formalisms for multivariate analysis [PDF]

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019
Multifractal analysis, that quantifies the fluctuations of regularities in time series or textures, has become a standard signal/image processing tool. It has been successfully used in a large variety of applicative contexts. Yet, successes are confined to the analysis of one signal or image at a time (univariate analysis). This is because multivariate

Multifractal analysis of earthquake catalogues [PDF]

Geophysical Journal International, 1995
SUMMARY We show that standard statistical analyses of earthquake Catalogues are not very useful tools for describing temporal variations of the seismic event clustering. A more appropriate approach is the rnultifractal analysis. In fact, if interarrival times between earthquakes are fractally distributed, this means that the behaviour of the catalogue ...

Multifractal Cross Correlation Analysis of Agro-Meteorological Datasets (Including Reference Evapotranspiration) of California, United States

, 2020
The multifractal properties of six acknowledged agro-meteorological parameters, such as reference evapotranspiration (ET0), wind speed (U), incoming solar radiation (SR), air temperature (T), air pressure (P), and relative air humidity (RH) of five ...

Analysis of Multifractals in Game Behaviors

Procedia Computer Science, 2012
AbstractWe study the diffusive process and the multifractal property in the Baduk. We are able to ascertain the superdiffusive process that the dispersion is proportional to tɛ with the scaling exponent ɛ =1.66±0.26 for our model. After simulating the multifractal behavior, we analyze the multifractal strength of three different segments.

Generalized energy inequalities and higher multifractal moments

, 2014
We present a class of generalized energy inequalities and indicate their use in investigating higher multifractal moments, in particular Lq-dimensions of images of measures under Brownian processes, Lq-dimensions of almost self-affine measures, and moments

Nonlinear Analysis of the U.S. Stock Market: From the Perspective of Multifractal Properties and Cross-Correlations with Comparisons

Fractal and Fractional
This study investigates the multifractal properties of daily returns of the Standard and Poor’s 500 Index (SPX), the Dow Jones Industrial Average (DJI), and the Nasdaq Composite Index (IXIC), the three main indices representing the U.S.
