Scattering from surface fractals in terms of composing mass fractals [PDF]

open access: yesJ. Appl. Cryst. 50, 919-931 (2017), 2015
We argue that a finite iteration of any surface fractal can be composed of mass-fractal iterations of the same fractal dimension. Within this assertion, the scattering amplitude of surface fractal is shown to be a sum of the amplitudes of composing mass fractals. Various approximations for the scattering intensity of surface fractal are considered.

Fractal Modeling and Fractal Dimension Description of Urban Morphology [PDF]

open access: yesEntropy, 2020,22: 961, 2018
The conventional mathematical methods are based on characteristic length, while urban form has no characteristic length in many aspects. Urban area is a measure of scale dependence, which indicates the scale-free distribution of urban patterns. Thus, the urban description based on characteristic lengths should be replaced by urban characterization ...

On Fractal Features and Fractal Linear Space About Fractal Continuous Functions [PDF]

open access: yesFractals, 29(1), 2021, 2021
This paper investigates fractal dimension of linear combination of fractal continuous functions with the same or different fractal dimensions. It has been proved that: (1) $BV_{I}$ all fractal continuous functions with bounded variation is fractal linear space; (2) ${}^{1}D_{I}$ all fractal continuous functions with Box dimension one is a fractal ...

Quadrilateral Labyrinth Fractals [PDF]

open access: yesarXiv, 2021
In this paper, a class of fractals, called quadrilateral labyrinth fractals, are introduced and studied. They are a special kind of fractals on any quadrilateral on the plane. This type of fractal is motivated by labyrinth fractal on the unit square and triangle, which were already studied. This paper mainly deals with the construction of quadrilateral

Crystallization of space: Space-time fractals from fractal arithmetic [PDF]

open access: yesChaos, Solitons and Fractals 83 (2016) 201-211, 2015
Fractals such as the Cantor set can be equipped with intrinsic arithmetic operations (addition, subtraction, multiplication, division) that map the fractal into itself. The arithmetics allows one to define calculus and algebra intrinsic to the fractal in question, and one can formulate classical and quantum physics within the fractal set. In particular,

Modern Paradigm Regarding Capital Markets: Fractal Market Hypothesis. Determination of the Hurst Exponent on the Romanian Capital Market

open access: yesEIRP Proceedings, 2022
Classical statistical and econometric theory, intended to provide functional forecasting models in capital markets, is the mathematical foundation for a number of theories - efficient market theory, Harry Markowitz's optimized portfolio theory, the ...

The Mellin Transform and Non-local Derivatives of Fractal Calculus [PDF]

open access: yesarXiv, 2023
In this paper, the fractal calculus of fractal sets and fractal curves are compared. The analogues of the Riemann-Liouville and the Caputo integrals and derivatives are defined for the fractal curves which are non-local derivatives. The analogous for the fractional Laplace concepts are defined to solve fractal non-local differential equations on ...

Fractal Calculus on Fractal Interpolation Functions

open access: yesFractal and Fractional, 2021
In this paper, fractal calculus, which is called Fα-calculus, is reviewed. Fractal calculus is implemented on fractal interpolation functions and Weierstrass functions, which may be non-differentiable and non-integrable in the sense of ordinary calculus.

Fractal kinetic characteristics of hard-rock uranium leaching with sulfuric acid [PDF]

open access: yesRoyal Society Open Science, 2018
In order to study the fractal dynamic properties of uranium leach mining and discuss the influence of ore crushing on the dynamics of leach mining, uranium mine ore rocks in southern China were selected as the research object and an acid leaching ...
