Research of the Bifurcation Characteristic of Helical Gear System with Considering Random Perturbation of Mesh Stiffness

open access: yesJixie chuandong, 2019
In order to study the influence of the random perturbation of time-varying mesh stiffness on the dynamics of the helical gearing system, based on Newton's law, a stochastic dynamics model of a six-degree-of-freedom helical gear system is established and ...

Dynamic bifurcation for the granulation convection in the solar photosphere

open access: yesBoundary Value Problems, 2017
The main objective of this paper is to investigate the dynamic bifurcation for the granulation convection in the solar photosphere. Based on the dynamic bifurcation theory, which is established by Ma and Wang (Phase transition dynamics, pp. 380-459, 2014)

Design of Positive, Negative, and Alternating Sign Generalized Logistic Maps

open access: yesDiscrete Dynamics in Nature and Society, 2015
The discrete logistic map is one of the most famous discrete chaotic maps which has widely spread applications. This paper investigates a set of four generalized logistic maps where the conventional map is a special case.

Some results on the dynamics generated by the Bazykin model

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2006
A predator-prey model formerly proposed by A. Bazykin et al. [Bifurcation diagrams of planar dynamical systems (1985)] is analyzed in the case when two of the four parameters are kept fixed.

Classification of solitary wave bifurcations in generalized nonlinear Schrödinger equations [PDF]

open access: yesarXiv, 2012
Bifurcations of solitary waves are classified for the generalized nonlinear Schr\"odinger equations with arbitrary nonlinearities and external potentials in arbitrary spatial dimensions. Analytical conditions are derived for three major types of solitary wave bifurcations, namely saddle-node bifurcations, pitchfork bifurcations and transcritical ...

The operating diagram of a flocculation model in the chemostat and its dependence on the biological parameters [PDF]

open access: yesarXiv, 2023
In this paper, we consider a flocculation model in a chemostat where one species is present in two forms: planktonic and aggregated bacteria with the presence of a single resource. The removal rates of isolated and attached bacteria are distinct and include the specific death rates.

Disjoint bifurcation diagrams in combustion systems

open access: yesMathematical and Computer Modelling, 1991
It is shown that the classical non-dimensionalisation of many simple combusting systems is sufficiently nonlinear to conceal some of the differences in behaviour shown when different bifurcation parameters are varied quasi-statically to produce bifurcation diagrams.

Entropy and Stability Analysis of Delayed Energy Supply–Demand Model

open access: yesEntropy, 2016
In this paper, a four-dimensional model of energy supply–demand with two-delay is built. The interactions among energy demand of east China, energy supply of west China and the utilization of renewable energy in east China are delayed in this model.

Big Bang Bifurcations in the Tantalus Oscillator under Biphasics Perturbations [PDF]

open access: yes, 2018
The Tantalus Oscillator is a non linear hydrodynamic oscillator with an attractive limit cycle. In this study we pursue the construction of a biparametric bifurcation diagram for the Tantalus Oscillator under biphasics perturbations. That is the first time that this kind of diagram is built for this kind of oscillator under biphasics perturbations ...
