chaos;bifurcation diagram;density;histogram;nonlinear system;
This work extends the construction of the density-colored bifurcation diagrams proposed by [Moysis et al., 2023] to continuous-time systems, and discusses several variations of them. These diagrams depict the histogram density of the local maxima in the underlying time series solution, using color g ...

This work studies a generalized version of a chaotic neural network model for epilepsy. The model consists of several activation functions that are coupled to simulate the neuronal stimulation. The system is in a chaotic regime for normal behavior, and in a periodic regime for epilepsy. By replacing ...

In light of the technological developments in modern society, there has been a global shift toward digitizing many aspects and tasks in our cities, leading to the birth of the term "smart city" [1]. The goals behind this steady transition are multilateral. They include energy efficiency, net-zero po ...

chaos;chaotification;dynamical system;nonlinear system;chaotic map;robust chaos;
This work provides a thorough review on the research topic of chaotification for discrete-time systems. Chaotification refers to the process of designing new chaotic maps, using existing maps from the literature as seed functions, with the goal of achieving a more complex behavior. This problem is o ...

Oznake:
chaos;chaotification;false attractor;nonlinear system;pseudo-random bit generator;
In this work, the use of false chaotic attractors in enhancing the security of chaos-based encryption applications will be explored. False attractors result by rearranging the solution trajectories of a nonlinear dynamical system, leading to novel shapes in the 3D space. This way, a single solution ...

This work proposes a family of modulo-based one-dimensional maps with three control parameters. The input to the modulo function includes the addition of three terms, the map’s previous value, a scalar, and a multiple of a chosen seed function. Under certain conditions, the proposed maps will have n ...

descriptor system;nonlinear system;observer design;singular system;differential algebraic equation;Lipschitz;quadratic constraints;chaos;synchronization;signal estimation;
In general, the construction of observers for nonlinear descriptor systems depends on the solvability of a linear matrix inequality involving system matrices, and it is based on the system’s nonlinearity. Therefore, the type of nonlinearity present in the system heavily affects the observer design p ...

Oznake:
chaos;nonlinear system;neural network;bifurcation;attention deficit disorder;
This work studies a modified chaotic neural network model consisting of two neurons for modeling attention deficit disorder. Considering an existing one-dimensional model from the literature, its two activation functions are replaced by the Soboleva hyperbolic tangent function. This change introduce ...

bit level;bit plane;chaos;chaotification;encryption;hidden attractor;pseudo-random number generator;
This work presents a chaotic image encryption algorithm that acts on the binary level of the image for effective permutation, and on the byte level for substitution. The permutation step combines actions of bit level rearranging, and bit shuffling. Circular shift operations are used for bit shufflin ...
