A new chaotic system with hidden attractor and its engineering applications: analog circuit realization and image encryption

Çavuşoğlu, Ünal; Shirin Panahi; Akgül, Akif; Sajad Jafari; Sezgin Kacar (SPRINGER, 2019)

In this article a simple chaotic flow with hidden attractor is proposed. Various dynamics of this new system such as periodic and chaotic oscillations can be achieved by setting bifurcation parameters in a proper value. ...
An exponential jerk system, its fractional-order form with dynamical analysis and engineering application

; Karthikeyan Rajagopal; Akgül, Akif; Sajad Jafari; Anitha Karthikeyan; Çavuşoğlu, Ünal; Kaçar, Sezgin (SPRINGER, 2020)

A simple jerk system with only one exponential nonlinearity is proposed and discussed. Dynamic analysis of the integer-order jerk system shows the existence of chaotic oscillations. A model for the fractional-order jerk ...
An Exponential Jerk System: Circuit Realization, Fractional Order and Time Delayed Form with Dynamical Analysis and Its Engineering Application

Karthikeyan Rajagopal; Akgül, Akif; Sajad Jafari; Anitha Karthikeyan; Çavuşoğlu, Ünal; Sezgin Kacar (WORLD SCIENTIFIC PUBL CO PTE LTD, 2019)

Simple dynamical systems are of interest always. In this paper, we propose a simple jerk system with one exponential nonlinearity. Dynamical properties of the proposed system are investigated. To show the practical ...
Multiscroll chaotic system with sigmoid nonlinearity and its fractional order form with synchronization application

Karthikeyan Rajagopal; Durdu, Ali; Sajad Jafari; Uyaroğlu, Yılmaz; Anitha Karthikeyan; Akgül, Akif (PERGAMON-ELSEVIER SCIENCE LTD, 2019)

In this paper, a multiscroll snap oscillator with hyperbolic tangent function is proposed. There is no limitation in the number of scrolls and it can be increased by proper choice of a specific function. The Lyapunov ...
