Hidden and Self-Excited Collective Dynamics of a New Multistable Hyper-Jerk System with Unique Equilibrium
Vijayakumar, M. D.; Natiq, Hayder; Leutcho, Gervais Dolvis; Rajagopal, Karthikeyan; Jafari, Sajad; Hussain, Iqtadar... more authors ... less authors (2022 , Article)Nonlinear dynamical systems with hidden attractors belong to a recent and hot area of research. Such systems can exist in different forms, such as without equilibrium or with a stable equilibrium point. This paper focuses ... -
Multistable dynamics and control of a new 4D memristive chaotic Sprott B system
Ramesh, Ramamoorthy; Rajagopal, Karthikeyan; Leutcho, Gervais Dolvis; Krejcar, Ondrej; Namazi, Hamidreza; Hussain, Iqtadar... more authors ... less authors ( Elsevier , 2022 , Article)This work proposes and investigates the dynamic behavior of a new memristive chaotic Sprott B system. One of the interesting features of this system is that it has a bias term that can adjust the symmetry of the proposed ... -
A Novel Highly Nonlinear Quadratic System: Impulsive Stabilization, Complexity Analysis, and Circuit Designing
Ramesh, Arthanari; Bahramian, Alireza; Natiq, Hayder; Rajagopal, Karthikeyan; Jafari, Sajad; Hussain, Iqtadar... more authors ... less authors ( Hindawi , 2022 , Article)This work introduces a three-dimensional, highly nonlinear quadratic oscillator with no linear terms in its equations. Most of the quadratic ordinary differential equations (ODEs) such as Chen, Rossler, and Lorenz have at ... -
A Simple Conservative Chaotic Oscillator with Line of Equilibria: Bifurcation Plot, Basin Analysis, and Multistability
Veeman, Dhinakaran; Natiq, Hayder; Ali, Ahmed M.Ali; Rajagopal, Karthikeyan; Hussain, Iqtadar ( Hindawi , 2022 , Article)Here, a novel conservative chaotic oscillator is presented. Various dynamics of the oscillator are examined. Studying the dynamical properties of the oscillator reveals its unique behaviors. The oscillator is multistable ... -
A simple one-dimensional map-based model of spiking neurons with wide ranges of firing rates and complexities
Alireza, Bahramian; Ramadoss, Janarthanan; Nazarimehr, Fahimeh; Rajagopal, Karthikeyan; Jafari, Sajad; Hussain, Iqtadar... more authors ... less authors ( Elsevier , 2022 , Article)This paper introduces a simple 1-dimensional map-based model of spiking neurons. During the past decades, dynamical models of neurons have been used to investigate the biology of human nervous systems. The models simulate ...
