Reading multifractal spectra: Aging by multifractal analysis of heart rate

EPL (Europhysics Letters), 2011
The method of effective reading of multifractal properties is proposed. The method consists in the analysis of a given signal together with the analysis of an integrated signal. A practical way to separate monofractal-type signals from other signals is given. The method is applied to 24-hour ECG recordings of RR-interbeat intervals to assess the effect

Multifractal radiographic analysis of osteoporosis

Medical Physics, 1994
An important complication of osteoporosis is fracture. Alteration in bone structure, as well as decreased bone mass, contribute to the tendency to fracture in osteoporosis. Current methods that measure bone mass alone show substantial overlap of the measurements of osteoporotic patients who fracture with those that do not.

Multifractal analysis of dimensions and entropies

Regular & chaotic dynamics, 2000
The article is a nice survey of various dimensions and entropies which are associated with attractors and dynamical systems and appeared in the last 30 years. The authors stressed their attention to the multifractal formalism which describes relations between various dimension characteristics of measures.

Multifractal analysis of ZnO nanoparticles

Materials Science and Engineering: C, 2020
ZnO nanoparticles (NPs) have variety of applications in different fields due to its size, structure, as well as physical and chemical properties. One of its prominent characteristics is its antibacterial behavior. Nonlinear Dynamical Theory (NLD) has a vast scope in the field of material science, especially when subtle correlations are searched for to ...

Image analysis using multifractals

1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002
The efficacy of the multifractal spectrum as a tool for characterizing images has been studied. This spectrum has been computed for digitized images of the nucleus of human cervical cancer cells and it was observed that the entire spectrum is almost fully reproduced for a normal cell while only the right half ...

Multifractal texture analysis and classification

Proceedings 1999 International Conference on Image Processing (Cat. 99CH36348), 2003
Existing fractal methods of texture analysis rely on the fractal dimension of textures as a function of scale for their discrimination and classification. We propose a method which is based on the possible multiscaling/multifractality of textures. A stochastic model is suggested to represent this multiscaling behaviour.

Multifractal Analysis of Hyperbolic Flows

Communications in Mathematical Physics, 2000
One of the main goals of this paper is to establish a version of the multifractal analysis for a class of hyperbolic flows and suspension flows over subshifts of finite type. As a consequence they show that for every Hölder continuous function non-cohomologous to a constant, the set of points without Birkhoff average has full topological entropy.

On the wavelet formalism for multifractal analysis

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2001
It is proved that the multifractal characterizations of diametrically regular measures that are provided by the wavelet and by the Hentschel–Procaccia formalisms are identical.
