Fractal Dimensions of Macromolecular Structures [PDF]
Molecular Informatics, 2014 AbstractQuantifying the properties of macromolecules is a prerequisite for understanding their roles in biochemical processes. One of the less‐explored geometric features of macromolecules is molecular surface irregularity, or ‘roughness’, which can be measured in terms of fractal dimension (D).

Signal Pattern Recognition Based on Fractal Features and Machine Learning
Applied Sciences, 2018 As a typical pattern recognition method, communication signal modulation involves many complicated factors. Fractal theory can be used for signal modulation feature extraction and recognition because of its good ability to express complex information. In

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.

A fractal model for the lightning induced current on a transmission line [PDF]
, 1997 This article presents a model of a tortuous lightning channel, and a study of the consequent electromagnetic coupling to a transmission line. We analyse the fractal dimension of the induced current on the line, compared with the fractal dimension of the ...

Estimating the Dimension of a Fractal
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1991 SUMMARY We suggest refinements of the box counting method which address the obvious problems caused by the incomplete information and inaccessibility of the limit. A method for the statistical analysis of these corrected data is developed and tested on simulated and real data.
