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

Applied 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 ...

Sucesiones y la dimensión fractal [PDF]

, 2012
A través de una serie de problemas, cuya solución nos sumerge en el mundo matemático de los procesos infinitos, en forma natural se llega a la idea de sucesión y límite de una sucesión. En algunos de los problemas planteados aparecen objetos geométricos,

Fractal dimension of cortical functional connectivity networks & severity of disorders of consciousness.

PLoS ONE, 2020
Recent evidence suggests that the quantity and quality of conscious experience may be a function of the complexity of activity in the brain and that consciousness emerges in a critical zone between low and high-entropy states.

An Investigation of Fractal Characteristics of Marine Shales in the Southern China from Nitrogen Adsorption Data

Journal of Chemistry, 2015
We mainly focus on the Permian, Lower Cambrian, Lower Silurian, and Upper Ordovician Formation; the fractal dimensions of marine shales in southern China were calculated using the FHH fractal model based on the low-pressure nitrogen adsorption analysis ...

A Novel Porous Media Permeability Model Based on Fractal Theory and Ideal Particle Pore-Space Geometry Assumption

Energies, 2020
In this paper, a novel porous media permeability model is established by using particle model, capillary bundle model and fractal theory. The three-dimensional irregular spatial characteristics composed of two ideal particles are considered in the model.

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.
