Dynamics of the verge and foliot clock escapement
P. Hoyng, A. C. T. Nieuwenhuizen
The verge and foliot escapement has received relatively little attention in horology, despite the fact that it has been used in clocks for ages. We analyse the operation of a verge…
Dynamics and performance of clock pendulums
Peter Hoyng
We analyze the dynamics of a driven, damped pendulum as used in mechanical clocks. We derive equations for the amplitude and phase of the oscillation, on time scales longer than th…
Mode analysis of numerical geodynamo models
Martin Schrinner, Dieter Schmitt, Peter Hoyng
It has been suggested in Hoyng (2009) that dynamo action can be analysed by expansion of the magnetic field into dynamo modes and statistical evaluation of the mode coefficients. W…
An efficient method for computing the eigenfunctions of the dynamo equation
M. Schrinner, D. Schmitt, J. Jiang +1
We present an elegant method of determining the eigensolutions of the induction and the dynamo equation in a fluid embedded in a vacuum. The magnetic field is expanded in a complet…
Saturation and time dependence of geodynamo models
M. Schrinner, D. Schmitt, R. Cameron +1
In this study we address the question under which conditions a saturated velocity field stemming from geodynamo simulations leads to an exponential growth of the magnetic field in…
Statistical dynamo theory: Mode excitation
P. Hoyng
We compute statistical properties of the lowest-order multipole coefficients of the magnetic field generated by a dynamo of arbitrary shape. To this end we expand the field in a co…
