Elasticity of Fractal Material by Continuum Model with Non-Integer Dimensional Space [PDF]

Comptes Rendus Mecanique. Vol.343. No.1. (2015) 57-73, 2015
Using a generalization of vector calculus for space with non-integer dimension, we consider elastic properties of fractal materials. Fractal materials are described by continuum models with non-integer dimensional space. A generalization of elasticity equations for non-integer dimensional space, and its solutions for equilibrium case of fractal ...

Probabilistic, Fractal, and Related Techniques for Analysis of Engineering Surfaces

Frontiers in Mechanical Engineering, 2020
In many engineering fields surface topography is of crucial importance solving problems of friction and other problems of tribology. A review of mathematical approaches for description of topography of engineering surfaces is presented.

Fractal Properties and Characterizations [PDF]

arXiv, 2020
There are three important types of structural properties that remain unchanged under the structural transformation of condensed matter physics and chemistry. They are the properties that remain unchanged under the structural periodic transformation-periodic properties. The properties that remain unchanged under the structural multi scale transformation-

Fractal sets satisfying the strong open set condition in complete metric spaces [PDF]

Opuscula Mathematica, 2008
Let \(K\) be a Hutchinson fractal in a complete metric space \(X\), invariant under the action \(S\) of the union of a finite number of Lipschitz contractions. The Open Set Condition states that \(X\) has a non-empty subinvariant bounded open subset \(V\)

FRACTAL IMAGE FEATURE VECTORS WITH APPLICATIONS IN FRACTOGRAPHY

Image Analysis and Stereology, 2011
The morphology of fatigue fracture surface (caused by constant cycle loading) is strictly related to crack growth rate. This relation may be expressed, among other methods, by means of fractal analysis.

Computational identification of antibody-binding epitopes from mimotope datasets

Frontiers in Bioinformatics
Introduction: A fundamental challenge in computational vaccinology is that most B-cell epitopes are conformational and therefore hard to predict from sequence alone. Another significant challenge is that a great deal of the amino acid sequence of a viral

The Fractal Calculus for Fractal Materials

Fractal and Fractional, 2019
The major problem in the process of mixing fluids (for instance liquid-liquid mixers) is turbulence, which is the outcome of the function of the equipment (engine). Fractal mixing is an alternative method that has symmetry and is predictable.

Numerical Simulation of the Fractal-Fractional Ebola Virus

Fractal and Fractional, 2020
In this work we present three new models of the fractal-fractional Ebola virus. We investigate the numerical solutions of the fractal-fractional Ebola virus in the sense of three different kernels based on the power law, the exponential decay and the ...

Dynamics of Forest Fragmentation and Connectivity Using Particle and Fractal Analysis

Scientific Reports, 2019
The ever decreasing area of forests has lead to environmental and economical challenges and has brought with it a renewed interest in developing methodologies that quantify the extent of deforestation and reforestation.

Looking under the lamp-post: quantifying the performance of contact tracing in the United States during the SARS-CoV-2 pandemic

BMC Public Health
Contact tracing forms a crucial part of the public-health toolbox in mitigating and understanding emergent pathogens and nascent disease outbreaks. Contact tracing in the United States was conducted during the pre-Omicron phase of the ongoing COVID-19 ...
