Examining the spatial configuration of street junctions across cities: a fractal approach on intra-urban clusters

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Urban streets form the backbone of cities, and variations in street-junction spatial configuration provide valuable insights into urban form and function, both of which exhibit fractal and scaling characteristics in their structural and statistical ...

Towards a More General Type of Univariate Constrained Interpolation With Fractal Splines

open access: yes, 2015
Recently, in [Electronic Transaction on Numerical Analysis, 41 (2014), pp. 420-442] authors introduced a new class of rational cubic fractal interpolation functions with linear denominators via fractal perturbation of traditional nonrecursive rational ...

Seepage Characteristics and Critical Scale in Gas-Bearing Coal Pores Under Water Injection: A Multifractal Approach

open access: yesFractal and Fractional
To investigate the flow characteristics of movable water in coal under the influence of micro-nano pore fractures with multiple fractal structures, this study employed nuclear magnetic resonance (NMR) and multifractal theory to analyze gas–water seepage ...

Day and Night Changes of Cardiovascular Complexity: A Multi-Fractal Multi-Scale Analysis

open access: yesEntropy, 2020
Recently, a multifractal-multiscale approach to detrended fluctuation analysis (DFA) was proposed to evaluate the cardiovascular fractal dynamics providing a surface of self-similarity coefficients α(q,τ), function of the scale τ, and moment order q.

A Study of the Fractal Bending Behavior of Timoshenko Beams Using a Fourth-Order Single Equation

open access: yesBuildings
In this paper a new generalized fractal equation for studying the behaviour of self-similar beams using the Timoshenko beam theory is introduced. This equation is established in fractal dimensions by applying the concept of fractal continuum calculus Fα ...

Power law viscoelasticity of a fractal colloidal gel

open access: yes, 2018
Power law rheology is of widespread occurrence in complex materials that are characterized by the presence of a very broad range of microstructural length and time scales.

Dynamic Scaling of an Adsorption-Diffusion Process on Fractals

open access: yes, 2005
A dynamic scaling of a diffusion process involving the Langmuir type adsorption is studied. We find dynamic scaling functions in one and two dimensions and compare them with direct numerical simulations, and we further study the dynamic scaling law on ...

Arithmetic-Analytic Representation of Peano Curve

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2019
In this work, we obtained a nonmatrix analytic expression for the generator of the Peano curve. Applying the iteration method of fractal, we established a simple arithmetic-analytic representation of the Peano curve as a function of ternary numbers.

First passage time processes and subordinated SLE

open access: yes, 2011
We study the first passage time processes of anomalous diffusion on self similar curves in two dimensions. The scaling properties of the mean square displacement and mean first passage time of the ballistic motion, fractional Brownian motion and ...
