Bilinear Fractal Interpolation and Box Dimension

open access: yesJournal of Approximation Theory, 2014
In the context of general iterated function systems (IFSs), we introduce bilinear fractal interpolants as the fixed points of certain Read-Bajraktarevi\'{c} operators.

Understanding 3D structural complexity of individual Scots pine trees with different management history

open access: yesEcology and Evolution, 2021
Tree functional traits together with processes such as forest regeneration, growth, and mortality affect forest and tree structure. Forest management inherently impacts these processes.

Box ladders in a noninteger dimension [PDF]

open access: yesTheoretical and Mathematical Physics, 2013
We construct a family of triangle-ladder diagrams which may be calculated by making use of Belokurov-Usyukina loop reduction technique in d = 4 -2e dimensions. The main idea of the approach proposed in the present paper consists in generalization of this loop reduction technique existing in d = 4 dimensions.

Determining method of multiscale fractal dimension of red bed sandstone pores based on CT scanning

open access: yes地质科技通报, 2022
The distribution of pore structure inside rock has fractal characteristics in statistical sense, the determination of itsfractal dimension is of great significance to characterize the distribution law of pore structure quantitatively and reveal various ...

Management and change in turbulent times: How do Russian small business managers perceive the development of their business environment?

open access: yesJournal of Business Economics and Management, 2008
This paper focuses on the management of small businesses in Russia. Despite the growing importance of the Russian small business sector, there are surprisingly few empirical studies focusing on this topic.

On distance sets, box-counting and Ahlfors-regular sets [PDF]

open access: yes, 2017
We obtain box-counting estimates for the pinned distance sets of (dense subsets of) planar discrete Ahlfors-regular sets of exponent $s>1$. As a corollary, we improve upon a recent result of Orponen, by showing that if $A$ is Ahlfors-regular of dimension

Experimental Study of the Multiple Fractalisation of Coal and Rock Failure Subjected to the Coupled Effects of Water, Temperature and Dynamic Loads

open access: yesApplied Sciences, 2023
The mechanical properties of water-rich coal and rock in a subzero environment are very different from those at room temperature, which causes many unexpected hazards for projects.

The horizon problem for prevalent surfaces [PDF]

open access: yes, 2011
We investigate the box dimensions of the horizon of a fractal surface defined by a function $f \in C[0,1]^2 $. In particular we show that a prevalent surface satisfies the `horizon property', namely that the box dimension of the horizon is one less than ...

Relative multifractal box-dimensions

open access: yesFilomat, 2019
Given two probability measures ? and ? on Rn. We define the upper and lower relative multifractal box-dimensions of the measure ? with respect to the measure ? and investigate the relationship between the multifractal box-dimensions and the relative multifractal Hausdorff dimension, the relative multifractal pre-packing dimension.
