Fractal Characteristics of Deep Shales in Southern China by Small-Angle Neutron Scattering and Low-Pressure Nitrogen Adsorption

open access: yesFractal and Fractional, 2022
The occurrence and flow of shale gas are substantially impacted by nanopore structures. The fractal dimension provides a new way to explore the pore structures of shale reservoirs. In this study, eight deep shale samples from Longmaxi Formation to Wufeng

Fractal Analysis of Vasomotion [PDF]

open access: yesAnnals of the New York Academy of Sciences, 1990
Random-like fluctuations have been observed in blood flow in the microvasculature. This we term flow motion, thus distinguishing it from the closely related phenomenon, vasomotion, which refers to fluctuations in vessel diameter. This intermittent perfusion of vascular beds has been observed in skeletal muscle,1 skin,2 mesentery,3 and brain.4 These ...

Fractal Analysis of Human Gait Variability via Stride Interval Time Series

open access: yesFrontiers in Physiology, 2020
Fractal analysis of stride interval time series is a useful tool in human gait research which could be used as a marker for gait adaptability, gait disorder, and fall risk among patients with movement disorders.

Drip paintings and fractal analysis [PDF]

open access: yesPhysical Review E, 2009
It has been claimed [1-6] that fractal analysis can be applied to unambiguously characterize works of art such as the drip paintings of Jackson Pollock. This academic issue has become of more general interest following the recent discovery of a cache of disputed Pollock paintings.

Modeling Urban Growth and Form with Spatial Entropy

open access: yes, 2020
Entropy is one of physical bases for fractal dimension definition, and the generalized fractal dimension was defined by Renyi entropy. Using fractal dimension, we can describe urban growth and form and characterize spatial complexity. A number of fractal

Formation of fractal structure in many-body systems with attractive power-law potentials [PDF]

open access: yes, 2005
We study the formation of fractal structure in one-dimensional many-body systems with attractive power-law potentials. Numerical analysis shows that the range of the index of the power for which fractal structure emerges is limited.

Evaluation of long term storage of apples by means of fractal analysis

open access: yesResearch in Agricultural Engineering, 2003
Realization of long-term apple storage requires the most detailed information about the flesh structure and texture, whose quality is contributing by responsible way to the whole quality of the evaluated fruits.
