Multiple-Layer Image Encryption Utilizing Fractional-Order Chen Hyperchaotic Map and Cryptographically Secure PRNGs

open access: yesFractal and Fractional, 2023
Image encryption is increasingly becoming an important area of research in information security and network communications as digital images are widely used in various applications and are vulnerable to various types of attacks.

Percolation and Internet Science

open access: yesFuture Internet, 2019
Percolation, in its most general interpretation, refers to the “flow„ of something (a physical agent, data or information) in a network, possibly accompanied by some nonlinear dynamical processes on the network nodes (sometimes denoted ...

Undecidable Properties of Limit Set Dynamics of Cellular Automata [PDF]

open access: yes, 2009
Cellular Automata (CA) are discrete dynamical systems and an abstract model of parallel computation. The limit set of a cellular automaton is its maximal topological attractor. A well know result, due to Kari, says that all nontrivial properties of limit

Coxeter Groups and Asynchronous Cellular Automata [PDF]

open access: yes, 2010
The dynamics group of an asynchronous cellular automaton (ACA) relates properties of its long term dynamics to the structure of Coxeter groups. The key mathematical feature connecting these diverse fields is involutions.

Formal Definitions of Unbounded Evolution and Innovation Reveal Universal Mechanisms for Open-Ended Evolution in Dynamical Systems

open access: yesScientific Reports, 2017
Open-ended evolution (OEE) is relevant to a variety of biological, artificial and technological systems, but has been challenging to reproduce in silico. Most theoretical efforts focus on key aspects of open-ended evolution as it appears in biology.

Complex Systems: A Survey [PDF]

open access: yes, 2011
A complex system is a system composed of many interacting parts, often called agents, which displays collective behavior that does not follow trivially from the behaviors of the individual parts.

Statistical Mechanics of Surjective Cellular Automata [PDF]

open access: yes, 2015
Reversible cellular automata are seen as microscopic physical models, and their states of macroscopic equilibrium are described using invariant probability measures.

On the Complexity of Limit Sets of Cellular Automata Associated with Probability Measures [PDF]

open access: yes, 2006
We study the notion of limit sets of cellular automata associated with probability measures (mu-limit sets). This notion was introduced by P. Kurka and A. Maass. It is a refinement of the classical notion of omega-limit sets dealing with the typical long

Universal Cellular Automata and Class 4 [PDF]

open access: yes, 1994
Wolfram has provided a qualitative classification of cellular automata(CA) rules according to which, there exits a class of CA rules (called Class 4) which exhibit complex pattern formation and long-lived dynamical activity (long transients).
