Chaotic Oscillations in a Fractional-Order Circuit with a Josephson Junction Resonator and Its Synchronization Using Fuzzy Sliding Mode Control
Ramakrishnan, Balamurali; Cimen, Murat Erhan; Akgul, Akif; Li, Chunbiao; Rajagopal, Karthikeyan; Kor, Hakan (Hindawi Ltd, 2022)A linear resistive capacitive inductive shunted model of a Josephson junction with a topologically nontrivial behaviour is considered in this paper. We have considered a fractional-order flux-controlled memristor to ... -
Complex bio rhythms
Akgul, Akif; Savi, Marcelo A.; Yildiz, Mustafa Zahid; Sanjuan, Miguel A. F.; Ma, Jun (Springer Heidelberg, 2022)Complex biorhythms are characteristic of ubiquitous phenomena appearing in many disciplines of human knowledge. This Special Issue collects articles devoted to different complex biorhythms phenomena such as cardiac dynamics, ... -
DWT-SVD Based Watermarking for High-Resolution Medical Holographic Images
Horasan, Fahrettin; Pala, Muhammed Ali; Durdu, Ali; Akgul, Akif; Akmese, Omer Faruk; Yildiz, Mustafa Zahid (Wiley-Hindawi, 2022)Watermarking is one of the most common techniques used to protect data's authenticity, integrity, and security. The obfuscation in the frequency domain used in the watermarking method makes the watermarking stronger than ... -
Electronic Circuit Implementations of a Fractional-Order Chaotic System and Observing the Escape from Chaos
Akgul, Akif; Adiyaman, Yusuf; Gokyildirim, Abdullah; Aricioglu, Burak; Pala, Muhammed Ali; Cimen, Murat Erhan (World Scientific Publ Co Pte Ltd, 2022)Studies on fractional-order chaotic systems have increased significantly in the last decade. This paper presents Rucklidge chaotic system's dynamical analyses and its fractional-order circuit implementations. Component ... -
A novel security and authentication method for infrared medical image with discrete time chaotic systems
Boyraz, Omer Faruk; Guleryuz, Emre; Akgul, Akif; Yildiz, Mustafa Zahid; Kiran, Harun Emre; Ahmad, Jawad (Elsevier Gmbh, 2022)Objective: Hand vein images have become important biometric signs used for identification systems. Also, dorsal hand vein images have noteworthy advantages in terms of reliability and contactless procedure. Surgically ...
