Quasicrystals in Vernam Cipher
We propose a modification of the classical Vernam cipher based on properties of one-dimensional quasicrystals. The method uses the sequence of quasicrystal minimal distances as an one-time pad. The main advantages are strict aperiod...

Quasicrystals: algebraic, combinatorial and geometrical aspects
The paper presents mathematical models of quasicrystals with particular attention given to cut-and-project sets. We summarize the properties of higher-dimensional quasicrystal models and then focus on the one-dimensional ones. For t...

Linear mappings as self-similarities of mathematical models of quasicrystals
-dimensional mathematical quasicrystal related to the Pisot number $1+2cos frac{2pi }{7. Moreover, it is shown that there exists a connection between the planar quasicrystal and higher-dimensional quasicrystal with 7-fold s...

Description of Voronoi tiles in quasicrystals withoctagonal symmetry
We describe families of Voronoi tiles which appear in tilings of certain standard quasicrystal-like point sets with octagonal symmetry built using the cut-and-project construction....

Beta-integers and Quasicrystals
Beta-integers were defined as a generalization of integers by Alfred Renyi in 1957. Besides mathematicians, this structure attracted attention of crystallographers who found out that beta-lattices are convenient for description of quasicrystals

Image Sampling with Quasicrystals
We investigate the use of quasicrystals in image sampling. Quasicrystals produce space-filling, non-periodic point sets that are uniformly discrete of the algebraic theory of cut-and-project quasicrystals based on the geome...

Thermal stability of Al-Cu-Fe quasicrystals prepared by SHS method
Quasicrystal-containing materials are usually prepared by rapid solidification of the melt (e.g. by melt spinning) or mechanical alloying. In this work, the method using exothermic reactions between compressed metallic powders called SHS (Se...
