This work presents a chaotification technique that makes use of the triangle wave function. This function is piecewise linear, periodic, and bounded, so it’s simple structure makes it a viable choice for chaotification. The chaotification technique is the composition of this function with any seed m ...

This work presents a numerical method to color the bifurcation diagram of any discrete map, based on the distribution of the map’s values in its domain. This density-colored diagram reveals information on the uniformity of the map’s value distribution across its domain set, as a bifurcation paramete ...

In this work, a family of piecewise chaotic maps is proposed. This family of maps is parameterized by the nonlinear functions used for each piece of the mapping, which can be either symmetric or non-symmetric. Applying a constraint on the shape of each piece, the generated maps have no equilibria an ...

Currently, chaotic cryptography is mainly concentrated on image encryption. Once-popular stream-encryption algorithms, e.g., textual data, are now rarely considered. This article studies how chaotic image-encryption algorithms can be used to encrypt text. The proposed approach to this problem consis ...

In a recent work by Rezende, Leys & Bouali (2022), the authors proposed the technique of rearranging the time series of chaotic trajectories, in order to generate visually stunning new attractors. These attractors were termed ‘false’, as they do not correspond to a solution of a chaotic system, but ...

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 paper presents a new method of generating chaotic maps that do not have fixed points. The method uses an appropriate transformation of functions defined on the unit square in such a way that the newly created projection has no fixed points. In this way, countless new chaotic mappings can be cre ...

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 ...

The understanding of nonlinear dynamics requires a solid background on differential equations, calculus, and numerical analysis. This is why the teaching of nonlinear dynamics and chaos is integrated in the later years of most curriculums of University Departments in the natural sciences. With chaot ...

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 ...
