Periodic Patterns of Signed Shifts [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 The periodic patterns of a map are the permutations realized by the relative order of the points in its periodic orbits. We give a combinatorial description of the periodic patterns of an arbitrary signed shift, in terms of the structure of the descent ...

Equi-topological entropy curves for skew tent maps in the square [PDF]
, 2015 We consider skew tent maps Tα, β(x) such that (α,β)∈[0,1]2 is the turning point of TTα, β, that is, Tα, β = βα $\begin{array}{} \frac{{\beta}}{{\alpha}} \end{array} $x for 0≤ x ≤ α and Tα, β(x) = β1−α $\begin{array}{} \frac{{\beta}}{1- {\alpha}} \end ...

Adaptive Color Image Encryption Scheme Based on Multiple Distinct Chaotic Maps and DNA Computing
Mathematics, 2022 In this paper, we propose an adaptive encryption scheme for color images using Multiple Distinct Chaotic Maps (MDCM) and DNA computing. We have chosen three distinct chaotic maps, including a 2D-Henon map, a Tent map, and a Logistic map, to separately ...

Design of Discretized Tent Map
The Journal of the Korea Contents Association, 2008 To present the design procedure of discretized 8-bit tent map executing the transformation of tent function which is one of the chaotic functions, first, the truth table of discretized tent map was written, and then according to the simplified Boolean algebra equations obtained from the truth table, the discretized map is implemented with the exclusive

Stability and expansivity of tent map
Proceedings of the American Mathematical Society, 2020 The paper is concerned with properties of stability for the (piecewise affine) tent map of the interval. The authors consider notions alternative to the topological stability. The first of them is orbit shift stability, which means that for \(C^0\)-small perturbations of a map from the tent family, the conjugacy between the shifts on the corresponding ...

Spatiotemporal chaotic one-way Hash function construction based on coupled tent maps
Tongxin xuebao, 2007 A novel coupled tent maps-based spatiotemporal chaotic cryptographic Hash function was proposed.Compared with the discrete tent map,the coupled discrete tent spatiotemporal chaotic maps have longer computer-realization-period,nearly uniform distribution ...

BER Performance Improvement of Dual Chaotic Maps Based on STBC Communication System
Al-Khawarizmi Engineering Journal, 2022 Sensitive information of any multimedia must be encrypted before transmission. The dual chaotic algorithm is a good option to encrypt sensitive information by using different parameters and different initial conditions for two chaotic maps.
