Fractal-based models for internet traffic and their application to secure data transmission [PDF]

open access: yes, 2006
This thesis studies the application of fractal geometry to the application of covert communications systems. This involves the process of hiding information in background noise; the information being encrypted or otherwise.

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.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

UAP Fractal Scaling

open access: yes
Unidentified aerial phenomena (UAP) intrigue scientists with reports of complex behaviors. This study will investigate if UAP sighting distributions exhibit fractal scaling spatially and temporally.

Topological texture-fractal processing of signals and fields in radiophysics, radio engineering and radiolocation: developed methods and technologies (1979 – 2022) - fractal engineering

open access: yesГеоконтекст, 2023
The report discusses the main directions of the introduction of textures, fractals, fractional operators, dynamic chaos and methods of nonlinear dynamics to create new information (breakthrough) technologies.

Renormalization analysis of continuum models on fractal domains [PDF]

open access: yes, 2012
This thesis builds on the recently begun extension of continuum thermomechanics to fractal media which are specified by a fractional mass scaling law of the resolution length scale R.

Single and multiscale remote sensing techniques, multifractals and MODIS derived vegetation and soil moisture

open access: yes, 2008
Scaling processes are increasingly understood to be the result of nonlinear dynamic mechanisms repeating scale after scale from large to small scales leading to nonclassical resolution dependencies.

Spatial metrics in fire ecology: seeking consistency amidst complexity

open access: yesBiological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Influences of Fractal Substrate Structures on Dynamic Scaling Behaviors of Etching Model

open access: yes, 2017
The Etching model on various fractal substrates embedded in two dimensions was investigated by means of kinetic Mento Carlo method in order to determine the relationship between dynamic scaling exponents and fractal parameters. The fractal dimensions are

Advances in causal discovery methods for ecological time series

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent advances in data collection technologies (e.g. automated sensor networks, satellite remote sensing, and high‐throughput sequencing) have greatly expanded the availability of ecological time series, enabling new opportunities for causal analyses in dynamic ecosystems.
