Oscillation threshold of a clarinet model: a numerical continuation approach
This paper focuses on the oscillation threshold of single reed instruments. Several characteristics such as blowing pressure at threshold, regime selection, and playing frequency are known to change…

Refractive index of a transparent liquid measured with a concave mirror
This paper describes the spherical concave mirror method for measuring the index of refraction of transparent liquids. We derived the refractive index equation using Snell's law and the…

Comparative study between toroidal coordinates and the magnetic dipole field
There is a similar behaviour between the toroidal coordinates and the dipole magnetic field produced by a circular loop. In this work we evaluate up to what extent the former can be used as a…

Self-attraction effect and correction on three absolute gravimeters
The perturbations of the gravitational field due to the mass distribution of an absolute gravimeter have been studied. The so called Self Attraction Effect (SAE) is crucial for the measurement…

Semi-analytical and numerical methods for computing transient waves in 2D acoustic / poroelastic stratified media
Wave propagation in a stratified fluid / porous medium is studied here using analytical and numerical methods. The semi-analytical method is based on an exact stiffness matrix method coupled with a…

Acoustic waves: should they be propagated forward in time, or forward in space?
The evolution of acoustic waves can be evaluated in two ways: either as a temporal, or a spatial propagation. Propagating in space provides the considerable advantage of being able to handle…

Finite volume methods for unidirectional dispersive wave models
We extend the framework of the finite volume method to dispersive unidirectional water wave propagation in one space dimension. In particular we consider a KdV-BBM type equation. Explicit and IMEX…

Coulomb's law in maximally symmetric spaces
We study the modifications to the Coulomb's law when the background geometry is a n-dimensional maximally symmetric space, by using of the n-dimensional version of the Gauss' theorem. It…

A Purely Classical Derivation of the Meissner Effect?
A recent study (arXiv:1109.1968v2, to be published in American Journal of Physics) claims to provide a classical explanation of the Meissner effect. However, the argument misuses de Gennes'…
