An Investigation of Fractal Characteristics of Marine Shales in the Southern China from Nitrogen Adsorption Data

open access: yesJournal of Chemistry, 2015
We mainly focus on the Permian, Lower Cambrian, Lower Silurian, and Upper Ordovician Formation; the fractal dimensions of marine shales in southern China were calculated using the FHH fractal model based on the low-pressure nitrogen adsorption analysis ...

Helicalised fractals

open access: yes, 2015
We formulate the helicaliser, which replaces a given smooth curve by another curve that winds around it. In our analysis, we relate this formulation to the geometrical properties of the self-similar circular fractal (the discrete version of the curved ...

Two Sets of Simple Formulae to Estimating Fractal Dimension of Irregular Boundaries

open access: yes, 2020
Irregular boundary lines can be characterized by fractal dimension, which provides important information for spatial analysis of complex geographical phenomena such as cities.

Transfer across Random versus Deterministic Fractal Interfaces

open access: yes, 2000
A numerical study of the transfer across random fractal surfaces shows that their responses are very close to the response of deterministic model geometries with the same fractal dimension. The simulations of several interfaces with prefractal geometries

Fractal Analysis of Fragmentation Distribution of Rockbursts Induced by Low-Frequency Seismic Disturbances

open access: yesAdvances in Civil Engineering, 2021
Low-frequency seismic disturbances frequently induce violent rockburst hazards, seriously threatening the safety of deep excavation and mining engineering.

Critical interfaces and duality in the Ashkin Teller model

open access: yes, 2010
We report on the numerical measures on different spin interfaces and FK cluster boundaries in the Askhin-Teller (AT) model. For a general point on the AT critical line, we find that the fractal dimension of a generic spin cluster interface can take one ...

Fractal analysis of leaves: are all leaves self-similar along the cane?

open access: yesEkológia (Bratislava), 2013
The fractal dimension can be used to quantify the shape of a natural curve. Curves with similar degrees of irregularity will tend to have the same fractal dimension.

Assouad Dimension and Fractal Geometry [PDF]

open access: yes, 2020
The Assouad dimension is a notion of dimension in fractal geometry that has been the subject of much interest in recent years. This book, written by a world expert on the topic, is the first thorough account of the Assouad dimension and its many variants and applications in fractal geometry and beyond.
