Relaxation to Fixed Points in the Logistic and Cubic Maps: Analytical and Numerical Investigation

Entropy, 2013
Convergence to a period one fixed point is investigated for both logistic and cubic maps. For the logistic map the relaxation to the fixed point is considered near a transcritical bifurcation while for the cubic map it is near a pitchfork bifurcation. We

Quadratic Function Chaotic System and its Application on Digital Image Encryption

IEEE Access, 2020
To obtain chaotic systems with good properties to help chaos based image encryption, this paper first study the condition under which quadratic functions can be used as pseudo-random sequence generator.

Nonequilibrium Probabilistic Dynamics of the Logistic Map at the Edge of Chaos

, 2002
We consider nonequilibrium probabilistic dynamics in logistic-like maps $x_{t+1}=1-a|x_t|^z$, $(z>1)$ at their chaos threshold: We first introduce many initial conditions within one among $W>>1$ intervals partitioning the phase space and focus on the ...

Analytical Study of the Julia Set of a Coupled Generalized Logistic Map

, 1998
A coupled system of two generalized logistic maps is studied. In particular influence of the coupling to the behaviour of the Julia set in two dimensional complex space is analyzed both analytically and numerically.

A Key Space Enhanced Chaotic Encryption Scheme for Physical Layer Security in OFDM-PON

IEEE Photonics Journal, 2017
In this paper, we propose a key space enhanced chaos-based encryption scheme with no requirement of redundant sideband information in an orthogonal frequency division multiplexing passive optical network (OFDM-PON).

Information Content of Turbulence

, 2013
We treat a turbulent velocity field as a message in the same way as a book or a picture. All messages can be described by their entropy per symbol $h$, defined as in Shannon's theory of communication.
