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. ...
A new hybrid approach for intrusion detection using machine learning methods

Çavuşoğlu, Ünal (SPRINGER, 2019)

In this study, a hybrid and layered Intrusion Detection System (IDS) is proposed that uses a combination of different machine learning and feature selection techniques to provide high performance intrusion detection in ...
A Novel Chaotic System With Boomerang-Shaped Equilibrium, Its Circuit Implementation and Application to Sound Encryption

Saleh Mobayen; Sundarapandian Vaidyanathan; Aceng Sambas; Sezgin Kacar; Çavuşoğlu, Ünal (SPRINGER INTERNATIONAL PUBLISHING AG, 2019)

In the chaos literature, there has been much attention paid to chaotic systems with uncountable equilibrium points such as systems with line equilibrium, curve equilibrium. This paper reports a 3-D chaotic system with a ...
A Novel Hypogenetic Chaotic Jerk System: Modeling, Circuit Implementation, and Its Application

; Jiancheng Liu; Karthikeyan Rajagopal; Tengfei Lei; Kaçar, Sezgin; Arıcıoğlu, Burak; Çavuşoğlu, Ünal; Kökçam, Abdullah Hulusi; Anitha Karthikeyan (HINDAWI LTD, 2020)

When revising the polarity and amplitude information in the feedback, a unique hypogenetic jerk system was obtained which has two controllers to switch the equilibria between stable and unstable. After providing some basic ...
A NOVEL S-BOX DESIGN ALGORITHM AND FUZZY-PID CONTROLLER DESIGN FOR A 5-D BURKE-SHAW SYSTEM WITH HIDDEN HYPERCHAOS

Qingxia Ma; Wenqiang Luo; Hadi Jahanshahi; Çavuşoğlu, Ünal; Kif Akgul; Xianguang Lin (ACTA PRESS, 2019)

This paper presents a new S-Box design algorithm of hidden hyperchaos in a 5-D hyperchaotic Burke-Shaw system, which is obtained by adding feedback controllers to the classic Burke-Shaw system. Of particular interest is ...
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 ...
S-Box Based Image Encryption Application Using a Chaotic System without Equilibrium

Xiong Wang; Çavuşoğlu, Ünal; Sezgin Kacar; Akgül, Akif (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 ...
