Regularity of multifractal spectra of conformal iterated function systems
, 2009 We investigate multifractal regularity for infinite conformal iterated function systems (cIFS). That is we determine to what extent the multifractal spectrum depends continuously on the cIFS and its thermodynamic potential.

A Multifractal Description of Wind Speed Records [PDF]
, 2004 In this paper, a systematic analysis of hourly wind speed data obtained from four potential wind generation sites in North Dakota is conducted. The power spectra of the data exhibited a power law decay characteristic of $1/f^{\alpha}$ processes with ...

Agribusiness, EarlyView.Abstract The vegetable market experiences significant price fluctuations due to the complex interplay of trend, cyclical, seasonal, and irregular factors. This study takes Korean green onions as an example and employs the Christiano–Fitzgerald filter and the CensusX‐13 seasonal adjustment methods to decompose its price into four components: trend ...

Multifractal Analysis of Choquet Capacities
Advances in Applied Mathematics, 1998 The authors sketch that in some applications a capacity is a better tool as a measure and the simplest generalization relaxing additivity constraint. For a sequence of Choquet capacities, a reference measure and a sequence of partitions of the interval \(\left[ 0,1\right[ \) they define different types of multifractal spectrum functions following the ...

Scale-Specific Multifractal Medical Image Analysis [PDF]
Computational and Mathematical Methods in Medicine, 2013 Fractal geometry has been applied widely in the analysis of medical images to characterize the irregular complex tissue structures that do not lend themselves to straightforward analysis with traditional Euclidean geometry. In this study, we treat the nonfractal behaviour of medical images over large-scale ranges by considering their box-counting ...

Multiscale characterization of pore spaces using multifractals analysis of scanning electronic microscopy images of carbonates [PDF]
Nonlinear Processes in Geophysics, 2011 Pore spaces heterogeneity in carbonates rocks has long been identified as an important factor impacting reservoir productivity. In this paper, we study the heterogeneity of carbonate rocks pore spaces based on the image analysis of scanning electron ...

Multifractality in the stock market: price increments versus waiting times
, 2004 By applying the multifractal detrended fluctuation analysis to the high-frequency tick-by-tick data from Deutsche B\"orse both in the price and in the time domains, we investigate multifractal properties of the time series of logarithmic price increments

Deep Underground Science and Engineering, EarlyView.The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Frontiers in Physics, 2020 The spatial distribution of a population is not homogeneous—some areas attract many residents, while others do not. The spatial distribution of stores and facilities that have been coevolving with that of the population is also heterogeneous.

Multifractal Characterization of Protein Contact Networks
, 2014 The multifractal detrended fluctuation analysis of time series is able to reveal the presence of long-range correlations and, at the same time, to characterize the self-similarity of the series.
