An encryption algorithm for color images based on an improved dual-chaotic system combined with DNA encoding [PDF]

open access: yesScientific Reports
This study improves the Logistic chaotic system and combines it with the hyperchaotic Chen system to create a dual chaotic system. The algorithm encrypts images in three stages. In the first stage, a plaintext-related key generation scheme is designed to

Dynamics, control, stability, diffusion and synchronization of modified chaotic Colpitts oscillator [PDF]

open access: yesArchives of Control Sciences, 2021
The purpose of this paper is to introduce a new chaotic oscillator. Although different chaotic systems have been formulated by earlier researchers, only a few chaotic systems exhibit chaotic behaviour.

Bifurcation analysis, circuit design and sliding mode control of a new multistable chaotic population model with one prey and two predators [PDF]

open access: yesArchives of Control Sciences, 2023
In this work, we report a new chaotic population biology system with one prey and two predators. Our new chaotic population model is derived by introducing two nonlinear interaction terms between the prey and predator-2 to the Samardzija-Greller ...

Leaking chaotic systems [PDF]

open access: yesReviews of Modern Physics, 2013
There are numerous physical situations in which a hole or leak is introduced in an otherwise closed chaotic system. The leak can have a natural origin, it can mimic measurement devices, and it can also be used to reveal dynamical properties of the closed system. In this paper we provide an unified treatment of leaking systems and we review applications

Realization of a novel chaotic system using coupling dual chaotic system [PDF]

open access: yesOptical and Quantum Electronics, 2021
Abstract This paper establishes coupling between two various chaotic systems for Lorenz and Rössler circuits. The x-dynamics of Lorenz circuit was coupled numerically with the x dynamics of Rössler circuit. As a result of the optical coupling between these two chaotic systems, it has been observed an exceptional variation in the time series and

Synchronization of chaotic systems [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2015
We review some of the history and early work in the area of synchronization in chaotic systems. We start with our own discovery of the phenomenon, but go on to establish the historical timeline of this topic back to the earliest known paper. The topic of synchronization of chaotic systems has always been intriguing, since chaotic systems are known to ...

Chaotic Systems with Absorption [PDF]

open access: yesPhysical Review Letters, 2013
Motivated by applications in optics and acoustics we develop a dynamical-system approach to describe absorption in chaotic systems. We introduce an operator formalism from which we obtain (i) a general formula for the escape rate $ $ in terms of the natural conditionally-invariant measure of the system; (ii) an increased multifractality when compared ...
