Analysis, FPGA implementation of a Josephson junction circuit with topologically nontrivial barrier and its application to ring-based dual entropy core true random number generator
Ramakrishnan, Balamurali; Oumate, Alhadji Abba; Tuna, Murat; Koyuncu, İsmail; Kingni, Sifeu Takougang; Rajagopal, Karthikeyan (Springer Heidelberg, 2021)The analysis and field programmable gate arrays (FPGA) implementation of a resistive-capacitive-inductive shunted Josephson junction (RCLSJJ) circuit with topologically nontrivial barrier (TNB) are investigated in this ... -
Control, synchronization with linear quadratic regulator method and FFANN-based PRNG application on FPGA of a novel chaotic system
Koyuncu, İsmail; Rajagopal, Karthikeyan; Alçın, Murat; Karthikeyan, Anitha; Tuna, Murat; Varan, Metin (Springer Heidelberg, 2021)In this work, LQR method is proposed for controlling and synchronizing newly developed chaotic system. The developed 4-D chaotic system has been investigated via time series, phase portraits and bifurcation diagrams. ... -
Dynamical analysis, sliding mode synchronization of a fractional-order memristor Hopfield neural network with parameter uncertainties and its non-fractional-order FPGA implementation
Rajagopal, Karthikeyan; Tuna, Murat; Karthikeyan, Anitha; Koyuncu, İsmail; Duraisamy, Prakash; Akgül, Akif (Springer Heidelberg, 2019)Recent developments in the applications of neural networks in various engineering and technology applications have motivated researchers to study the nonlinear behavior of such networks. In this work we investigate a ... -
Hyperjerk multiscroll oscillators with megastability: Analysis, FPGA implementation and a novel ANN-ring-based True Random Number Generator
Tuna, Murat; Karthikeyan, Anitha; Rajagopal, Karthikeyan; Alçın, Murat; Koyuncu, İsmail (Elsevier Gmbh, 2019)Metastable oscillators are a special case of chaotic attractors with infinite coexisting attractors. In this paper we propose a class of hyperjerk chaotic oscillators which exhibits megastability with and without forcing ... -
A Novel Simple 4-D Hyperchaotic System with a Saddle-Point Index-2 Equilibrium Point and Multistability: Design and FPGA-Based Applications
Prakash, Pankaj; Rajagopal, Karthikeyan; Koyuncu, İsmail; Singh, Jay P.; Alçın, Murat; Roy, Binoy K.; Tuna, Murat (Springer Birkhauser, 2020)This paper presents a novel simple 4-D dissipative autonomous hyperchaotic system with a saddle-point index-2 equilibrium point. The dynamics of the new system consists of nine terms with two nonlinear terms. Thus, the ...
