Chaos controls of a duffing system with impacts
AIP Advances, 2018 The chaos controls of a Duffing system with impacts are investigated using appropriate random phase. Based on the discontinuous map and Wedig’s algorithm, a procedure of calculating top Lyapunov exponent is presented for stochastic Duffing system with ...

Bifurcation, chaos analysis and control in a discrete-time predator–prey system
Advances in Difference Equations, 2019 The dynamical behavior of a discrete-time predator–prey model with modified Leslie–Gower and Holling’s type II schemes is investigated on the basis of the normal form method as well as bifurcation and chaos theory.

Mechanism of the Gas-Liquid Two-Phase Chaotic Flow in Single Fracture
Geofluids, 2020 The seepage of gas-liquid two-phase flow in fracture is a commonly found phenomenon in nature. To reveal the underlying mechanism and the critical condition of the chaos occurrence, a stochastic gas-liquid two-phase flow seepage model is established, and

IEEE Photonics Journal, 2013 This paper demonstrated the suppression of chaos in an Nd:YVO4 laser by reshaping the pump modulation with dual waveforms. When the first sinusoidal modulation induced chaos, the second modulated signal reshaped the modulated profile to suppress the ...

Predicting the chaos and solution bounds in a complex dynamical system [PDF]
, 2021 The competitive modes for a nonlinear chaotic complex system are studied in this paper. In hyperchaotic, chaotic, and periodic cases, we examined competitive modes that are a tool for detecting chaos in a system.

Chaotic motion of vibro-impact system based on Galerkin-Ivanov transformation
Xi'an Gongcheng Daxue xuebao, 2021 Based on the Galerkin-Ivanov transformation, the chaotic motion of a vibro-impact system was investigated. For a general vibro-impact system with one-side rigid, the equivalent smooth system with symmetric structure was obtained by Galerkin-Ivanov ...

Dynamical topology and statistical properties of spatiotemporal chaos
, 2012 For spatiotemporal chaos described by partial differential equations, there are generally locations where the dynamical variable achieves its local extremum or where the time partial derivative of the variable vanishes instantaneously. To a large extent,

Detection of the onset of numerical chaotic instabilities by lyapunov exponents
Discrete Dynamics in Nature and Society, 2001 It is commonly found in the fixed-step numerical integration of nonlinear differential equations that the size of the integration step is opposite related to the numerical stability of the scheme and to the speed of computation.

Reliability of Numerical Solutions in Transient Chaos
, 2023 In dealing with nonlinear systems, it is common to use numerical solutions. Unlike the careful behavior towards the numerical results in chaotic regions, the validity of numerical results in regions of transient chaos might not always be taken into consideration.
