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. ... -
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 ...
