A new 4-D chaotic hyperjerk system, its synchronization, circuit design and applications in RNG, image encryption and chaos-based steganography

S. Vaidyanathan; Akgül, Akif; Kaçar, Sezgin; Çavuşoğlu, Ünal (SPRINGER HEIDELBERG, 2018)

Hyperjerk systems have received significant interest in the literature because of their simple structure and complex dynamical properties. This work presents a new chaotic hyperjerk system having two exponential nonlinearities. ...
A novel approach for strong S-Box generation algorithm design based on chaotic scaled Zhongtang system

Çavuşoğlu, Ünal; Zengin, Ahmet; Pehlivan, İhsan; Kaçar, Sezgin (SPRINGER, 2017)

Substitution Box (S-Box) is one of the most significant structures used to create an encryption which is strong and resistant against attacks in block encryption algorithms. S-Box plays an important role in data encryption. ...
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 ...
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 ...
Crowd sensing aware disaster framework design with IoT technologies

Kerem Kucuk; Bayılmış, Cüneyt; Ahmet Furkan Sonmez; Kaçar, Sezgin (SPRINGER HEIDELBERG, 2020)

When a disaster occurs, a huge amount of inconsistent victim or damage information data is received by many different sources. Disaster management systems achieve the completion of a significantly vital task, which is to ...
New class of chaotic systems with equilibrium points like a three-leaved clover

Saleh Mobayen; Christos K. Volos; Kaçar, Sezgin; Çavuşoğlu, Ünal (SPRINGER, 2018)

This paper presents a new class of chaotic systems with infinite number of equilibrium points like a three-leaved clover. They signify an exciting class of dynamical systems which represent many major characteristics of ...
Secure image encryption algorithm design using a novel chaos based S-Box

Çavuşoğlu, Ünal; Kaçar, Sezgin; Pehlivan, İhsan; Zengin, Ahmet (PERGAMON-ELSEVIER SCIENCE LTD, 2017)

In this study, an encryption algorithm that uses chaos based S-BOX is developed for secure and speed image encryption. First of all, a new chaotic system is developed for creating S-Box and image encryption algorithm. Chaos ...
Volterra serileri ile sistemlerin frekans boyutunda analizi için .net tabanlı web arayüzü tasarımı

Kaçar, Sezgin (Sakarya Üniversitesi, 2010)

Sistemlerin incelenirken birçok sınıfa ayrılırlar. Bu incelemeler yapılırken farklı sınıflar için farklı analiz metotları kullanılır. Bu metotlardan birisi de doğrusal olmayan sistemlerin analizini frekans boyutunda ...
