Research on a Fractal Dimension Calculation Method for a Nano-Polymer Microspheres Dispersed System

Frontiers in Chemistry, 2021
Polymer microspheres (PMs) are a kind of self-similar volume expansion particle, and their fractal dimension varies with hydration swelling. However, there is no unique fractal dimension calculation method for their characteristics.

Box-Counting Dimension Using Triangles

, 2016
An alternate definition of the box-counting dimension is proposed, to provide a better approximation for fractals involving rotation such as the 'Bradley Spiral' structure. A curve fitting comparison of this definition with the box-counting dimension is also presented.

Fractal Analysis of Volcanic Rock Image Based on Difference Box-Counting Dimension and Gray-Level Co-Occurrence Matrix: A Case Study in the Liaohe Basin, China

Fractal and Fractional
Volcanic rocks, as a widely distributed rock type on the earth, are mostly buried deep within basins, and their internal structures possess characteristics by irregularity and self-similarity.

Fractal dimension and vessel complexity in patients with cerebral arteriovenous malformations. [PDF]

PLoS ONE, 2012
The fractal dimension (FD) can be used as a measure for morphological complexity in biological systems. The aim of this study was to test the usefulness of this quantitative parameter in the context of cerebral vascular complexity.

Microstructure quantitative analysis of multi-scale pores in C/SiC composites via micro-CT for revealing correlations with interlaminar shear properties

Journal of Materials Research and Technology
Fiber reinforced Ceramic Matrix composites (CMCs) are widely used in aerospace fields due to their excellent properties. However, pores are inevitable during CMCs manufacturing, due to their anisotropy and fabrication complexity.

The Application of Computed Tomography to Study the Soil Porosity of Mountain Red Earth

Applied Sciences
Mountain red soil, as a special type of soil in the South, has received widespread attention for its soil erosion problems. Its pore structure restricts water infiltration, thereby affecting the occurrence and development of soil erosion.

Génération de semis de points fractals : une méthode du comptage de boites inversée

Cybergeo, 2015
Fractal dimension is useful to characterize the structure of spatial objects such as urban structures or river networks. However, fractal analysis is underutilized for point processes.
