2:1 Resonance in the delayed nonlinear Mathieu equation
Averaging Degenerate Hopf Delay Nonlinear Mathieu Parametric excitation
2015/8/27
We investigate the dynamics of a delayed nonlinear Mathieu equation:¨ x + (δ + εα cost)x + εγx 3 = εβx(t − T) in the neighborhood of δ = 1/4. Three different phe-nomena are combined in this syst...
Hopf Bifurcations in Two-Strategy Delayed Replicator Dynamics
Replicator Delay Hopf bifurcation Limit cycle Lindstedt
2015/8/26
We investigate the dynamics of two-strategy replicator equations in which the fitness of each strategy is a function of the population frequencies delayed by a time interval T. We analyze two models: ...

Traditional structural feedback control systems are centralized systems. The applications of these systems to large scale structures usually encounter a number of difficulties regarding system reliabi...
Michelson Interferometer With Faraday Mirrors Employed In A Delayed Self-Heterodyne Interferometer
Coherent optical effects Heterodyne Interferometry
2011/5/25
Faraday rotator mirrors in a Michelson interferometer configuration is shown to significantly improve resolution and coherence for delayed self-heterodyne interferometery.Coherence is clearly observed...
Transient behavior in systems with time-delayed feedback
time-delayed feedback steady states
2009/12/9
We investigate the transient times for the onset of control of steady states by time-delayed feedback. The optimization of control by minimising the transient time before control becomes effective is ...
