Bifurcation and Chaos Prediction in Nonlinear Gear Systems

open access: yesShock and Vibration, 2014
The homoclinic bifurcation and transition to chaos in gear systems are studied both analytically and numerically. Applying Melnikov analytical method, the threshold values for the occurrence of chaotic motion are obtained.

The bifurcation diagram of a wavelet function

open access: yes, 2006
The bifurcation diagram of a wavelet function is discussed in the paper. The chaotic property of the map is changed with the variations of the constant k.

Bifurcation of positive solutions for the one-dimensional (p,q)-Laplace equation

open access: yesElectronic Journal of Differential Equations, 2017
In this article, we study the bifurcation of positive solutions for the one-dimensional (p,q)-Laplace equation under Dirichlet boundary conditions. We investigate the shape of the bifurcation diagram and prove that there exist five different types of

Analysis on recurrence behavior in oscillating networks of biologically relevant organic reactions

open access: yesMathematical Biosciences and Engineering, 2019
In this paper, we present a new method based on dynamical system theory to study certain type of slow-fast motions in dynamical systems, for which geometric singular perturbation theory may not be applicable.

The Complete Bifurcation Diagram for the Logistic Map

open access: yes, 1997
The complete bifurcation diagram as well as the basin of attraction for the logistic map is presented for the whole range of the control parameters, namely -2≤a≤4 where the system remains finite.
