Pseudofractals and the box counting algorithm [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2001
We show that for sets with the Hausdorff--Besicovitch dimension equal zero the box counting algorithm commonly used to calculate Renyi exponents ($d_q$) can exhibit perfect scaling suggesting non zero $d_q$'s. Properties of these pathological sets ({\it pseudofractals}) are investigated.

Improved Image Analysis Method to Evaluate Tracking Property under Successive Flashover Based on Fractal Theory

open access: yesEnergies, 2021
Successive flashover would result in carbonized tracking on insulator surface and cause deterioration to the insulation. Thus, investigation of the tracking can be beneficial in understanding flashover characteristics during long-term operation.

Accuracy Analysis of the Box-Counting Algorithm

open access: yesActa Physica Polonica A, 2012
Accuracy of the box-counting algorithm for numerical computation of the fractal exponents is investigated. To this end several sample mathematical fractal sets are analyzed. It is shown that the standard deviation obtained for the fit of the fractal scaling in the log-log plot strongly underestimates the actual error.

The box-merging implementation of the box-counting algorithm

open access: yesJournal of the Mechanical Behavior of Materials, 2016
Fractal analysis is a powerful tool for the classification of materials. However, until now, there were no efficient tools that could process large or color images due to the processing time required.

On the equality of Hausdorff and box counting dimensions [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 1993
By viewing the covers of a fractal as a statistical mechanical system, the exact capacity of a multifractal is computed. The procedure can be extended to any multifractal described by a scaling function to show why the capacity and Hausdorff dimension are expected to be equal.

Influence of the Fractal Geometry on the Mechanical Resistance of Cantilever Beams Designed through Topology Optimization

open access: yesApplied Sciences, 2021
In this work, the complex geometry of beams obtained from topology optimization is characterized through the fractal dimension (FD). The fractal dimension is employed as an efficiency measure of the mass distribution in the beams, that is, the capacity ...
