Images of Sierpinkski fractals underpinning Nature Physics 15, 127(2019)
, 2021 This dataset contains experimental and simulated (muffin-tin) images of Sierpinski fractals, created by positioning CO molecules on a Cu(111) surface.

, 2007 Impossible objects are a type of optical illusion involving ambiguous visual descriptions of figures that cannot physically exist. It is shown by way of example that such objects can be further developed using standard fractal techniques to create new ...

Using Fractals in Information Hiding [PDF]
Engineering and Technology Journal, 2009 Fractals are generated by simple, recursive calculations. Encryption anddecryption algorithms that take advantage of fractals are developed. This paper presents a new approach for information hiding using iterated function system (IFS) this approach ...

Configurations in fractals [PDF]
Rocky Mountain Journal of Mathematics, 2021 We define the manifold of configurations to be the quotient set of $k$ points in Euclidean space identified under congruence, and prove that compact subsets of $\mathbb{R}^d, d \geq 2$, of large Hausdorff dimension have a non-null set of configurations in them.

From Fractal Groups to Fractal Sets [PDF]
, 2003 This paper is a survey, with few proofs, of ideas and notions related to self-similarity of groups, semi-groups and their actions. It attempts to relate these concepts to more familiar ones, such as fractals, self-similar sets, and renormalizable dynamical systems.

Comptes Rendus. Mathématique, 2020 This appendix gives a lower bound of the Billingsley-Hausdorff dimension of a level set related to Birkhoff average in the “non-compact” symbolic space $\mathbb{N}^{\mathbb{N}}$, defined by Gibbs measure.

Explicit Spectral Decimation for a Class of Self-Similar Fractals
Abstract and Applied Analysis, 2013 The method of spectral decimation is applied to an infinite collection of self-similar fractals. The sets considered are a generalization of the Sierpinski Gasket to higher dimensions; they belong to the class of nested fractals and are thus very ...

The Structure of Mn and Co Nanoparticles Obtained in Direct Surfactant Micelles [PDF]
Журнал нано- та електронної фізики, 2017 The article deals with synthesis of Co and Mn nanoparticles in micellar aqueous solutions of cetyl pyridinium chloride. The nanoparticles (3-4В nm) and the spherical fractals (50, 150, 500 nm) have been identified with electron spectroscopy, dynamic ...

TUBE FORMULAS FOR GRAPH-DIRECTED FRACTALS
, 2010 Lapidus and Pearse proved recently an interesting formula about the volume of tubular neighborhoods of fractal sprays, including the self-similar fractals. We consider the graph-directed fractals in the sense of graph self-similarity of Mauldin-Williams
