Calculation of multi-fractal dimension of coal measure sedimentary rock and analysis of influencing factors

open access: yes矿业科学学报, 2021
In order to characterize the pore structure and fractal characteristics of coal-measure sedimentary rocks, three types of typical sedimentary rocks of the Middle Jurassic shale, mudstone and sandstone were selected as the research objects.

The Fractal Dimension of SAT Formulas [PDF]

open access: yes, 2014
Modern SAT solvers have experienced a remarkable progress on solving industrial instances. Most of the techniques have been developed after an intensive experimental testing process. Recently, there have been some attempts to analyze the structure of these formulas in terms of complex networks, with the long-term aim of explaining the success of these ...

A fractal model for the lightning induced current on a transmission line [PDF]

open access: yes, 1997
This article presents a model of a tortuous lightning channel, and a study of the consequent electromagnetic coupling to a transmission line. We analyse the fractal dimension of the induced current on the line, compared with the fractal dimension of the ...

Macaques preferentially attend to visual patterns with higher fractal dimension contours. [PDF]

open access: yes, 2019
Animals' sensory systems evolved to efficiently process information from their environmental niches. Niches often include irregular shapes and rough textures (e.g., jagged terrain, canopy outlines) that must be navigated to find food, escape predators ...
