Multifractal hardness analysis of rollerrolls

open access: yesPhysical Metallurgy and Heat Treatment of Metals, 2018
Аннотация. Постановка задачи. В связи с технологией производства и эксплуатацией проводить оценку механических свойств  массивных чугунных  отливок не  всегда возможно с помощью натурных испытаний.  Поэтому прогноз  свойств,  в частности листопрокатных чугунных валков, осуществляют с помощью моделирования путем анализа влияния параметров технологии.  К

Modeling and forecasting time series of precious metals: a new approach to multifractal data

open access: yesFinancial Innovation, 2019
We introduce a novel approach to multifractal data in order to achieve transcended modeling and forecasting performances by extracting time series out of local Hurst exponent calculations at a specified scale.

Fractal Anatomy of Human Organs: A Narrative Review of Structure, Function, and Clinical Perspectives

open access: yesClinical Anatomy, Volume 39, Issue 2, Page 273-280, March 2026.
ABSTRACT Fractal geometry describes complex, self‐similar patterns that repeat across spatial scales and is increasingly recognized as relevant in anatomical research. Indeed, the fractal organization is consistently observed in respiratory, cardiovascular, gastrointestinal, nervous, renal, hepatic, and dermatological systems.

Dynamical variety of shapes in financial multifractality

open access: yes, 2018
The concept of multifractality offers a powerful formal tool to filter out multitude of the most relevant characteristics of complex time series. The related studies thus far presented in the scientific literature typically limit themselves to evaluation

Forecasting Carbon Prices: A Literature Review

open access: yesJournal of Forecasting, Volume 45, Issue 2, Page 496-529, March 2026.
ABSTRACT Carbon emissions trading is utilized by a growing number of states as a significant tool for addressing greenhouse gas emissions (GHG), global warming problem and the climate crisis. Accurate forecasting of carbon prices is essential for effective policy design and investment strategies in climate change mitigation.

Construction of a Simple Multifractal Spectrum as an Alternative to the Legendre Spectra in Multifractal Formalisms

open access: yesRecoletos Multidisciplinary Research Journal, 2013
It is important to realize at the beginning of a statistical analysis whether the data are from a monofractal or multifractal distribution because the methods of analysis are different for each. In seismic sequence analysis, for instance, the monofractal
