Fractal Analysis of Particle Distribution and Scale Effect in a Soil–Rock Mixture
Fractal and Fractional, 2022 A soil–rock mixture (SRM) is a type of heterogeneous geomaterial, and the particle distribution of SRM can be described by fractal theory. At present, it is difficult to quantify the fractal dimension of a particle size distribution and understand the ...

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

Understanding the Fractal Dimensions of Urban Forms through Spatial Entropy
Entropy, 2017 The spatial patterns and processes of cities can be described with various entropy functions. However, spatial entropy always depends on the scale of measurement, and it is difficult to find a characteristic value for it.

Modeling Urban Growth and Form with Spatial Entropy
Complexity, 2020 Entropy is one of the physical bases for the fractal dimension definition, and the generalized fractal dimension was defined by Renyi entropy. Using the fractal dimension, we can describe urban growth and form and characterize spatial complexity.
