Fractal Derivatives, Fractional Derivatives and q-Deformed Calculus
Entropy, 2023 This work presents an analysis of fractional derivatives and fractal derivatives, discussing their differences and similarities. The fractal derivative is closely connected to Haussdorff’s concepts of fractional dimension geometry.

Determination of the Fractal Dimension of CO2 Adsorption Isotherms on Shale Samples
Geofluids, 2022 The fractal theory has been widely applied to the analysis of gas adsorption isotherms, which are used for the pore structure characterization in unconventional reservoirs. Fractal dimension is a key parameter that can indicate the complexity of the pore

Fractals Analysis of Cardiac Arrhythmias [PDF]
The Scientific World JOURNAL, 2005 Heart rhythms are generated by complex self-regulating systems governed by the laws of chaos. Consequently, heart rhythms have fractal organization, characterized by self-similar dynamics with long-range order operating over multiple time scales. This allows for the self-organization and adaptability of heart rhythms under stress.

On the Lebesgue measure of one generalised set of subsums of geometric series
Математичні СтудіїIn the present paper, we study a set that can be treated as a generalised set of subsums for a geometric series. This object was discovered independently in various mathematical aspects.

FracL: A Tool for Characterizing the Fractality of Landscape Gradients from a New Perspective
ISPRS International Journal of Geo-Information, 2019 The past several years have witnessed much progress in landscape ecology and fractal analysis. In landscape ecology, the gradient model of landscape patterns (i.e., landscape gradient) has emerged as a new operating paradigm, where most landscape metrics

Fractal Analysis Of Colors And Shapes For Natural And Urbanscapes URBANSCAPES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 Fractal analysis has been applied in many fields since it was proposed by Mandelbrot in 1967. Fractal dimension is a basic parameter of fractal analysis.
