Spatial Resonance

The experimental work of Franklin, Price & Williams (1973) shows that for moderately large driving amplitudes there are features of spatial resonance that are not predicted by the model representation of Mahony & Smith (1972). We here derive an alternative model, which remains valid for moderately large driving amplitudes, and we are able to obtain a theoretical description of both hysteresis and nonlinear detuning of the low frequency wave response. An experiment in which surface waves were generated by a sinusoidal pressure field at the free surface (and which corresponds almost exactly to the theoretical problem) was conducted in order to test these predictions.

Rayleigh Benard

The onset of convection in systems that are heated via current dissipation in the lower boundary or that lose heat from the top boundary via Newton's law of cooling is formulated as a bifurcation problem. The Rayleigh number as usually defined is shown to be inappropriate as a bifurcation parameter since the temperature difference across the layer depends on the amplitude of convection and hence changes as convection evolves at fixed external parameter values. A modified Rayleigh number is introduced that does remain constant even when the system is evolving, and solutions obtained with the standard formulation are compared with those obtained via the new one. Near the 1 : 2 spatial resonance in low Prandtl number fluids these effects open up intervals of Rayleigh number with no stable solutions in the form of steady convection or steadily traveling waves. Direct numerical simulations in two dimensions show that in such intervals the dynamics typically take the form of a nearly heteroclinic modulated traveling wave. This wave may be quasiperiodic or chaotic.

This chapter discusses a very early work by Nicola Lefanu, But Stars Remaining. This song highlights the composer’s flair and professionalism, revealing a keen awareness of practical issues and of the concerns of the performer. The piece has clear notation, with careful attention to detailed interpretative niceties. Although written originally for soprano, the work could also suit a flexible tenor. The composer envisages it being sung spontaneously, as from a high rock, with echoes reverberating, so there are plenty of gaps in the music to allow for spatial resonance. There are a good many innovative vocal devices and gestures for the singer to get used to, and the composer has annotated these meticulously. Conventional notation is mostly employed, apart from a few freer passages, where note-stems are absent.
