On the relationship of fractal geometry and tree–stand metrics on point clouds derived from terrestrial laser scanning

open access: yesMethods in Ecology and Evolution, 2020
Fractals have been widely used to determine bifurcation patterns in trees or to analyse the homeostasis of the development of plants to different environments. In a few instances, fractals have been used to predict tree or stand metrics. Here, we explore

Design of a wideband terahertz metamaterial absorber based on Pythagorean-tree fractal geometry

open access: yes, 2020
Broadband absorption in the terahertz regime is a challenge and onerous to realize with a single layer metasurface. Self-similarity in fractal structures are exploiting metamaterial characteristics that offer a promising platform to design wideband ...

Application of concentration-area fractal method in static modeling of hydrocarbon reservoirs

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
Separating and identifying various fractal communities are the most crucial steps in static reservoir modeling. There are different ways for the identification and separation which vary from simple statistical methods (on the basis of statistical ...

Fractal Geometry of Higher Derivative Gravity [PDF]

open access: yesPhysical Review Letters, 2020
We determine the scaling properties of geometric operators such as lengths, areas, and volumes in models of higher derivative quantum gravity by renormalizing appropriate composite operators. We use these results to deduce the fractal dimensions of such hypersurfaces embedded in a quantum spacetime at very small distances.

A review of fractals in karst

open access: yesInternational Journal of Speleology, 2019
Many features of a karst massif can either be modelled using fractal geometry or have a fractal distribution. For the exokarst, typical examples include the geometry of the landscape and the spatial location and size-distribution of karst depressions ...

Fractal Geometry in Designing and Operating Water Networks

open access: yes, 2020
Fractals are self-similar sets that cannot be easily described by classical geometry. Fractal sets have been implemented in almost all areas of human activity since they were introduced to science by Mandelbrot in 1982.

Fractal geometry in the nucleus [PDF]

open access: yesThe EMBO Journal, 2010
In his groundbreaking work, ‘The Fractal Geometry of Nature’ (Mandelbrot, 1982), Benoit Mandelbrot described how fractals could account for a long list of natural forms ranging from trees to coastlines. Two recent studies in Science and The EMBO Journal have suggested that chromatin and the nucleoplasmic space surrounding it should be added to the ...

Fractal geometry and multifractals in analyzing and processing medical data and images [PDF]

open access: yesArchive of Oncology, 2002
A traditional way for describing objects, based on the well-known Euclidean geometry, is not capable to describe different natural objects and phenomena such as clouds, relief shapes, trends in economy, etc.
