A New 4-D Hyperchaotic System with Four-Scroll Hidden Attractor, Its Properties and Bifurcation Analysis

, 2019
This paper announces a new four-dimensional hyperchaotic system with a four-scroll attractor and discusses its dynamic properties such as Lyapunov exponents, phase portraits, Kaplan-Yorke dimension and equilibrium points. Our calculations show that the

A generalized attention deficit disorder chaotic model with Soboleva hyperbolic tangent functions

This work studies the problem of modeling Attention Deficit Disorder (ADD) using a previously reported one dimensional map, but by replacing its two hyperbolic tangent activation functions, with Soboleva hyperbolic tangent ones.

Application of a hyperbolic tangent chaotic map to random bit generation and image encryption

In this paper, a two-parameter one-dimensional chaotic map with hyperbolic tangent and two nested sinusoidal terms is proposed. The reported map exhibits rich chaotic behavior including such phenomena as the period-doubling route to chaos, crisis, and ...

Ekeland variational principles for vector equilibrium problems [PDF]

Producción CientíficaThis work concerns Ekeland variational principles for scalar and vector cyclically antimonotone bifunctions on complete metric spaces. The scalar results work for extended bifunctions and they are obtained by a generalized version of

Medical data encryption based on a modified sinusoidal 1D chaotic map and its microcontroller implementation

This work considers a modification of the map proposed in Wang et al. (2020), by replacing its fixed term by a squared hyperbolic tangent term. The modified map is studied and is shown to have a plethora of chaos related phenomena, like period doubling ...

Analysis and electronic implementation of an absolute memristor autonomous Van der Pol-Duffing circuit

, 2019
In this paper, a memristor-based chaotic circuit is built by replacing the nonlinear resistor of a unified Van der Pol-Duffing circuit by an ideal and active flux-controlled memristor with an absolute value nonlinearity.
