A third-order class-D amplifier with and without ripple compensation
Stephen M. Cox, H. du Toit Mouton
We analyse the nonlinear behaviour of a third-order class-D amplifier, and demonstrate the remarkable effectiveness of the recently introduced ripple compensation (RC) technique in…
Solitons in a parametrically driven damped discrete nonlinear Schrödinger equation
M. Syafwan, H. Susanto, S. M. Cox
We consider a parametrically driven damped discrete nonlinear Schrödinger (PDDNLS) equation. Analytical and numerical calculations are performed to determine the existence and stab…
The Nikolaevskiy equation with dispersion
Eman Simbawa, Paul C. Matthews, Stephen M. Cox
The Nikolaevskiy equation was originally proposed as a model for seismic waves and is also a model for a wide variety of systems incorporating a neutral, Goldstone mode, including…
Pattern formation in the damped Nikolaevskiy equation
S. M. Cox, P. C. Matthews
The Nikolaevskiy equation has been proposed as a model for seismic waves, electroconvection and weak turbulence; we show that it can also be used to model transverse instabilities…
Persistent localized states for a chaotically mixed bistable reaction
Stephen M. Cox
We describe the evolution of a bistable chemical reaction in a closed two-dimensional chaotic laminar flow, from a localized initial disturbance. When the fluid mixing is sufficien…
A bistable reaction--diffusion system in a stretching flow
Stephen M. Cox, Georg A. Gottwald
We examine the evolution of a bistable reaction in a one-dimensional stretching flow, as a model for chaotic advection. We derive two reduced systems of ordinary differential equat…
