Fractal Analysis of Particle Distribution and Scale Effect in a Soil–Rock Mixture

Fractal and Fractional, 2022
A soil–rock mixture (SRM) is a type of heterogeneous geomaterial, and the particle distribution of SRM can be described by fractal theory. At present, it is difficult to quantify the fractal dimension of a particle size distribution and understand the ...

The fractal structure of the universe : a new field theory approach [PDF]

, 1998
While the universe becomes more and more homogeneous at large scales, statistical analysis of galaxy catalogs have revealed a fractal structure at small-scales (\lambda < 100 h^{-1} Mpc), with a fractal dimension D=1.5-2 (Sylos Labini et al 1996).

Coalgebraic Representation Theory of Fractals

Electronic Notes in Theoretical Computer Science, 2010
AbstractWe develop a representation theory in which a point of a fractal specified by metric means (by a variant of an iterated function system, (IFS) is represented by a suitable equivalence class of infinite streams of symbols. The framework is categorical: symbolic representatives carry a final coalgebra; an IFS-like metric specification of a ...
