Study on the Stability and Entropy Complexity of an Energy-Saving and Emission-Reduction Model with Two Delays

open access: yesEntropy, 2016
In this paper, we build a model of energy-savings and emission-reductions with two delays. In this model, it is assumed that the interaction between energy-savings and emission-reduction and that between carbon emissions and economic growth are delayed ...

Global Analysis of a Liénard System with Quadratic Damping

open access: yesDiscrete Dynamics in Nature and Society, 2018
In this paper, the global analysis of a Liénard equation with quadratic damping is studied. There are 22 different global phase portraits in the Poincaré disc.

Semi-global analysis of periodic and quasi-periodic k:1 and k:2 resonances [PDF]

open access: yes
The present paper investigates a family of nonlinear oscillators at Hopf bifurcation, driven by a small quasi-periodic forcing. In particular, we are interested in the situation that at bifurcation and for vanishing forcing strength, the driving ...

Dynamic Modeling and Nonlinear Vibration Research of the Rotary Cutting Mechanism Based on Bond Graphs

open access: yesJixie chuandong
The quality of the cut end surface of pipelines is one of the important factors to ensure the safe operation of the pipeline system. However, the existence of nonlinear factors in the pipeline cutting process may lead to chaos, quasi-periodic and other ...

Qualitative bifurcation diagrams

open access: yes, 2014
This thesis explores the use of qualitative reasoning to predict the behavior of a dynamical system given a change in one of its parameters based upon a qualitative representation of its bifurcation diagram. Three algorithms were developed to perform this task.

A new four-dimensional chaotic attractor

open access: yesAin Shams Engineering Journal, 2018
A new four-dimensional chaotic system is introduced in this paper, it is mainly consist of four multiplier terms and four simple terms. The system has different structure and topology of existing four-dimensional systems and produces two equilibrium ...
