Oznake: spominski Hindmarsh-Rose model;diskretni sistemi;razlike frakcijskega reda;memristive Hindmarsh-Rose model;discrete systems;fractional-order differences;
Discrete systems can offer advantages over continuous ones in certain contexts, particularly in terms of simplicity and reduced computational costs, though this may vary depending on the specific application and requirements. Recently, there has been growing interest in using fractional differences ...

Fractional-order models describing neuronal dynamics often exhibit better compatibility with diverse neuronal firing patterns that can be observed experimentally. Due to the overarching significance of synchronization in neuronal dynamics, we here study synchronization in multiplex neuronal networks ...

Oznake: chaos;pseudo-random bit generator;path planning;chaotic mobile robot;UAV;nonlinear system;PRBG;
This work proposes a one-dimensional chaotic map with a simple structure and three parameters. The phase portraits, bifurcation diagrams, and Lyapunov exponent diagrams are first plotted to study the dynamical behavior of the map. It is seen that the map exhibits areas of constant chaos with respect ...

Assessing the stability of synchronization is a fundamental task when studying networks of dynamical systems. However, this becomes challenging when the coupled systems are not exactly identical, as is al ways the case in practical settings. Here we introduce an extension of the Master Stability Fun ...

Modification of the logistic map using fuzzy numbers with application to pseudorandom number generation and image encryption
Lazaros Moysis, Christos Volos, Sajad Jafari, Jesus Manuel Muñoz-Pacheco, Jacques Kengne, Karthikeyan Rajagopal, Ioannis Stouboulos
Izvirni znanstveni članek
Oznake: chaos;nonlinear system;pseudo-random bit generator;encryption;cryptography;fuzzy number;
A modification of the classic logistic map is proposed, using fuzzy triangular numbers. The resulting map is analysed through its Lyapunov exponent (LE) and bifurcation diagrams. It shows higher complexity compared to the classic logistic map and showcases phenomena, like antimonotonicity and crisis ...
