A simple and efficient method for creating a motion trajectory is presented with an aim to achieve sufficient coverage of a given terrain. A chaotic map has been used in order that the motion trajectory should be unpredictable. The chaotic path generator which has been created, is used for implement ...

This work proposes a modified logistic map based on the system previously proposed by Han in 2019. The constructed map exhibits interesting chaos related phenomena like antimonotonicity, crisis, and coexisting attractors. In addition, the Lyapunov exponent of the map can achieve higher values, so th ...

This work introduces an encryption scheme for gray-scale plain-text images, which is based on a chaotic map. Initially, the proposed chaotic map, which is a modification of the Renyi map, is introduced and is utilized in defining a Pseudo-Random Bit Generator. Subsequently, a finite automaton is int ...

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 ...

Oznake: chaos;nonlinear system;microcontroller;simulation;circuit;education;stem;FPGA;
An ARM-FPGA-based interface for implementing nonlinear systems through project-based learning for undergraduate students is presented in this work. This setup has a low cost and can be utilized in courses (post-graduate and under-graduate) related to dynamical systems to show the complex behaviors s ...
