An Efficient Chaos-Based Image Encryption Technique Using Bitplane Decay and Genetic Operators
Social networks have greatly expanded in the last ten years the need for sharing multimedia data. However, on open networks such as the Internet, where security is frequently compromised, it is simple for eavesdroppers to approach the actual contents ...

Energy and the Macrodynamics of Agrarian Societies
For the present work, we utilized Leslie White’s anthropological theory of cultural evolutionism as a theoretical benchmark for econometrically assessing the macrodynamics of energy use in agrarian societies that constituted the human civilization’s ...

The onset and bifurcation points of n-cycles of several polynomial maps are located through a characteristic equation connecting cyclic polynomials of the cycle points. The polynomials satisfied by the parameters of the logistic, Hénon, and cubic maps at the onset and bifurcation points are obtained for n up to 14, 9, and 9, respectively.

Security Improve in ZigBee Protocol Based on RSA Public Algorithm in WSN [PDF]
ZigBee is consuming low energy and providing the protection in Wireless Sensor Networks. ZigBee pro is supporting most applications. In spite of improved the security, ZigBee pro weak in key administration. In this paper, we depend on Logistic Map Diffie

Chaos of Exponential Logistic Map
In this paper, chaos of a new exponential logistic map modulated by Gaussian function is investigated. Firstly, the stability of the fixed point is analyzed, and the occurrence of period doubling bifurcation in the system is verified theoretically ...

The dynamics of coupled logistic maps
<abstract><p>This paper considers a coupled system given by two logistic maps with the same parameter. We studied the existence and stability of fixed points outside the diagonal and estimated the regions where the synchronization to the diagonal, both chaotic and regular, is possible.

Delayed coupling of logistic maps [PDF]
We study the synchronization of logistic maps in a one-way coupling configuration. The master system is coupled to the slave system with a delay n(1), and the slave is a delayed logistic map with a delay n(2). We show that when the slave system has no delay (n(2)=0), perfectly synchronized solutions exist for strong enough coupling.

ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
