Tone generation in an open-end organ pipe: How a resonating sphere of air stops the pipe
Bernhardt H. Edskes, David T. Heider, Johan L. van Leeuwen +2
According to the classical Helmholtz picture, an organ pipe while generating its eigentone has two anti-nodes at the two open ends of a cylinder, the anti-nodes being taken as boun…
Geometric Perturbation Theory for a Class of Fiber Bundles
David T. Heider, J. Leo van Hemmen
A systematic study of small, time-dependent, perturbations to geometric wave-equation domains is hardly existent. Acoustic enclosures are typical examples featuring locally reactin…
Exact Solution for the Stokes Problem of an Infinite Cylinder in a Fluid with Harmonic Boundary Conditions at Infinity
Andreas N. Vollmayr, Jan-Moritz P. Franosch, J. Leo van Hemmen
We present an exact solution for the time-dependent Stokes problem of an infinite cylinder of radius r=a in a fluid with harmonic boundary conditions at infinity. This is a 3-dimen…
Crumpling of Curved Sheets: Generalizing Foeppl-von Karman
J. Leo van Hemmen, Mark A. Peterson
We generalize the Föppl-von Kármán equations to an initially precurved sheet and present the underlying derivation. A geometrically computed moment of strain replaces the notion of…
Spatiotemporal adaptation through corticothalamic loops: A hypothesis
Ulrich Hillenbrand, J. Leo van Hemmen
The thalamus is the major gate to the cortex and its control over cortical responses is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant i…
