Combining topology and fractal dimension of fracture networks to characterise structural domains in thrusted limestones [PDF]

open access: yes, 2021
Fractures in limestones of the Palaeocene Lockhart Formation in the hanging wall of the Himalayan Main Boundary Thrust north of Islamabad are examined, and the data analysed using a combination of topology and fractal dimension to characterise fracture ...

Stage division of urban growth based on logistic model of fractal dimension curves

open access: yesResults in Physics, 2023
The time series of fractal dimension values of urban form always take on sigmoid curves. The basic model of these curves is logistic function. From the logistic model of fractal dimension curves, we can derive the speed formula and acceleration formula ...

Fractal dimension for fractal structures

open access: yesTopology and its Applications, 2014
The main goal of this paper has a double purpose. On the one hand, we propose a new definition in order to compute the fractal dimension of a subset respect to any fractal structure, which completes the theory of classical box-counting dimension. Indeed, if we select the so called natural fractal structure on each euclidean space, then we will get the ...

THE FRACTAL DIMENSION OF AN OIL SPRAY [PDF]

open access: yesFractals, 2003
We study the fractal dimension of the contour of the liquid-gas interface in a spray. Our images include both the linking region and the break-up region, and are obtained with a high-resolution shadowgraph technique. This means that the images can then be subjected to an intensity filtering, equivalent to a threshold analysis, that enables the ...

Predictive modeling of low-temperature performance of SMA-13 cold-patching asphalt mixtures based on fractal theory [PDF]

open access: yesE3S Web of Conferences
In order to study the relationship between the low-temperature performance of cold-patching asphalt mixtures and the fractal of gradation, 13 groups of SMA-13 gradations were designed, and then the low-temperature performance test of cold-patching ...

Fractal Dimensions of Macromolecular Structures [PDF]

open access: yesMolecular Informatics, 2014
AbstractQuantifying the properties of macromolecules is a prerequisite for understanding their roles in biochemical processes. One of the less‐explored geometric features of macromolecules is molecular surface irregularity, or ‘roughness’, which can be measured in terms of fractal dimension (D).

Ultimate state and probability of particle breakage for rockfill materials based on fractal theory

open access: yesYantu gongcheng xuebao, 2021
In order to study the particle breakage rules of rockfill with fractal gradation, a large-scale triaxial test equipment for coarse soil is used to carry out particle breakage experiments under different confining pressures for scaled rockfill materials ...

Signal Pattern Recognition Based on Fractal Features and Machine Learning

open access: yesApplied Sciences, 2018
As a typical pattern recognition method, communication signal modulation involves many complicated factors. Fractal theory can be used for signal modulation feature extraction and recognition because of its good ability to express complex information. In

Research on a Fractal Dimension Calculation Method for a Nano-Polymer Microspheres Dispersed System

open access: yesFrontiers in Chemistry, 2021
Polymer microspheres (PMs) are a kind of self-similar volume expansion particle, and their fractal dimension varies with hydration swelling. However, there is no unique fractal dimension calculation method for their characteristics.
