A Chaotic System with Infinite Equilibria and Its S-Box Constructing Application
Wang, Xiong; Akgül, Akif; Çavuşoğlu, Ünal; Viet-Thanh Pham; Duy Vo Hoang; Xuan Quynh Nguyen (Mdpi, 2018)Systems with many equilibrium points have attracted considerable interest recently. A chaotic system with a line equilibrium has been studied in this work. The system has infinite equilibria and exhibits coexisting chaotic ... -
Multistability and Coexisting Attractors in a New Circulant Chaotic System
Rajagopal, Karthikeyan; Akgül, Akif; Viet-Thanh Pham; Alsaadi, Fawaz E.; Nazarimehr, Fahimeh; Alsaadi, Fuad E.; Jafari, Sajad (World Scientific Publ Co Pte Ltd, 2019)In this paper, a new four-dimensional chaotic flow is proposed. The system has a cyclic symmetry in its structure and shows a complicated, chaotic attractor. The dynamical properties of the system are investigated. The ... -
A new fractional-order hyperchaotic memristor oscillator: Dynamic analysis, robust adaptive synchronization, and its application to voice encryption
Jahanshahi, Hadi; Yousefpour, Amin; Munoz-Pacheco, Jesus M.; Kaçar, Sezgin; Viet-Thanh Pham; Alsaadi, Fawaz E. (Elsevier Science Inc, 2020)The present study proposes a new fractional-order hyperchaotic memristor oscillator. The proposed system is studied through numerical simulations and analyses, such as the Lyapunov exponents, bifurcation diagrams, and phase ... -
S-Box Based Image Encryption Application Using a Chaotic System without Equilibrium
Wang, Xiong; Çavuşoğlu, Ünal; Kaçar, Sezgin; Akgül, Akif; Viet-Thanh Pham; Jafari, Sajad; Xuan Quynh Nguyen (Mdpi, 2019)Chaotic systems without equilibrium are of interest because they are the systems with hidden attractors. A nonequilibrium system with chaos is introduced in this work. Chaotic behavior of the system is verified by phase ... -
Simulation and experimental implementations of memcapacitor based multi-stable chaotic oscillator and its dynamical analysis
Akgül, Akif; Kengne, Jacques; Rajagopal, Karthikeyan; Viet-Thanh Pham; Varan, Metin; Karthikeyan, Anitha; Kutlu, Mustafa Çağrı (Iop Publishing Ltd, 2021)In this work, linear quadratic regulator (LQR) method is proposed for controlling and synchronizing memcapacitor based chaotic system (MMCO). The MMCO is constructed with a charge controller memcapacitor, a resistor, a ...
