Study of Period-doubling Bifurcations of a Vibro-impact System
工程科学与技术, 2006 :In order to study the relation of the period-doubling bifurcation and the Hopf bifurcation,the period-doubling bifurcation problems of a vibro-impact system is investigated when the periodical solutions lose its stability.

Electronic implementation of a repressilator with quorum sensing feedback.
PLoS ONE, 2013 We investigate the dynamics of a synthetic genetic repressilator with quorum sensing feedback. In a basic genetic ring oscillator network in which three genes inhibit each other in unidirectional manner, an additional quorum sensing feedback loop ...

Period doubling bifurcations in a two-box model of the Brusselator [PDF]
Applications of Mathematics, 1983 Let us consider the system of ordinary differential equations (1) \(\dot x=v(x,\mu)\), where \(x=[x_ 1,y_ 1,x_ 2,y_ 2]\in {\mathbb{R}}^ 4\), \(\mu \in {\mathbb{R}}^ 1\) is a parameter and vector field \(v(\cdot,\mu)\) is invariant under the diffeomorphism g for every \(\mu\in {\mathbb{R}}\). The diffeomorphism g is defined by the following relation \(g(

Controlling hopf bifurcations: Discrete-time systems
Discrete Dynamics in Nature and Society, 2000 Bifurcation control has attracted increasing attention in recent years. A simple and unified state-feedback methodology is developed in this paper for Hopf bifurcation control for discrete-time systems. The control task can be either shifting an existing

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in

Symmetry Bifurcation and Chaos of the Poincaré Map, in a Three degree-of-freedom Vibro impact System
工程科学与技术, 2008 :A three degree-of-freedom vibro impact system with symmetric constraining stops is considered. The Poincaré map of the system is established, and the symmetry of the Poincaré map is derived in detail. The theory of bifurcation of fixed points is applied
