Multifractal analysis of earthquake catalogues [PDF]

open access: yesGeophysical 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 Analysis of Hydrologic Data Using Wavelet Methods and Fluctuation Analysis

open access: yesDiscrete 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

open access: yesEntropy, 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 ...

Multifractal analysis of multiview 3D video with different quantization parameters applying histogram method [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2014
In this paper, multifractal properties of multiview 3D video are determined. Multifractal spectra are determined by using the histogram method. For the analysis of multiview video, long video traces are used, for multiview video with two views ...

Multifractal Analysis on the Sphere [PDF]

open access: yes, 2008
A new generation of instruments in astrophysics or vision now provide spherical data. These spherical data may present a self- similarity property while no spherical analysis tool is yet available to characterize this property. In this paper we present a first numerical study of the extension of multifractal analysis onto the sphere using spherical ...

Wavelet Leaders in Multifractal Analysis [PDF]

open access: yes, 2007
The properties of several multifractal formalisms based on wavelet coefficients are compared from both mathematical and numerical points of view. When it is based directly on wavelet coefficients, the multifractal formalism is shown to yield, at best, the increasing part of the weak scaling exponent spectrum.

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

open access: yesJournal 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 ...

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

open access: yesFractal 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.
