Almost additive multifractal analysis

Journal de Mathématiques Pures et Appliquées, 2009
For the class of almost additive sequences, the authors establish a conditional variational principle for the dimension spectra in the context of the nonadditive thermodynamic formalism. This generalizes the classical thermodynamic formalism, by replacing the topological pressure of a single function by the topological pressure of a sequence of ...

Multifractal Measures and Singularity Analysis of Rainfall Time Series in the Semi-Arid Central Mexican Plateau

Atmosphere
A multifractal formalism relates multiscale quantities to the multifractal spectrum. The multifractal framework provides significant analytical advantages by incorporating a wide range of statistical moment orders (q), thereby enabling a more ...

A preliminary studyof the site-dependence of the multifractalfeatures of geoelectric measurements

Annals of Geophysics, 2004
Multifractal analysis was performed to characterize the fluctuations in dynamics of the hourly time variability of self-potential signals measured from January 2001 to September 2002 by three stations installed in the Basilicata region ...

Evidence of multifractality from emerging European stock markets.

PLoS ONE, 2012
We test for the presence of multifractality in the daily returns of the three most important stock market indices from Central and Eastern Europe, Czech PX, Hungarian BUX and Polish WIG using the Empirical Mode Decomposition based Multifractal Detrended ...

An introduction to Mandelbrot cascades

, 2014
In this course, we propose an elementary and self-contained introduction to canonical Mandelbrot random cascades. The multiplicative construction is explained and the necessary and sufficient condition of non-degeneracy is proved.

A Mathematical Review and Improvement of the Multifractal Analysis

IEEE Access
This article presents a focused mathematical study of multifractal analysis, building on previous applications to reservoir rock characterization. Here, we revisit the theoretical foundations by summarizing key multifractal measures and classification ...

Detection of Pipeline Leaks Using Fractal Analysis of Acoustic Signals

Fractal and Fractional
In this paper, the possibility of using monofractal and multifractal analysis of acoustic signals of pipelines to detect leaks is considered. An experimental stand has been created to study the fractal characteristics of acoustic signals of pipelines ...
