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

open access: yesEkológia (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.

A survey on fractal dimension for fractal structures

open access: yes, 2016
Along the years, the foundations of Fractal Geometry have received contributions starting from mathematicians like Cantor, Peano, Hilbert, Hausdorff, Carathéodory, Sierpiński, and Besicovitch, to quote some of them.

Study on the Fractal Characteristics of the Pomegranate Biotite Schist under Impact Loading

open access: yesGeofluids, 2021
In order to study the fractal characteristics of the pomegranate biotite schist under the effect of blasting loads, a one-dimensional SHPB impact test was carried out to test the dynamic compressive strength, damage morphology, fracture energy ...

Integrated Metallo‐Dielectric 3D Hotspots From High Refractive Index Nanodiamond‐Plasmonic Gold Cryosoret Nano‐Assemblies for Photonic Crystal Enhanced Fluorescence

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Understanding the Fractal Dimensions of Urban Forms through Spatial Entropy

open access: yesEntropy, 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.

Fractal Dimension of Disordered Submonolayers: Determination from He Scattering Data

open access: yes, 1996
We propose a novel method to measure the fractal dimension of a submonolayer metal adatom system grown under conditions of limited diffusivity on a surface.
