Another study shortly after [12] showed that the exact nature of the zonal ows (in par-ticular, their equatorial symmetry) in the SSL is highly important, and there can be scenarios where zonal ows in the SSL may destabilize the dynamo and help pro-duce non-axisymmetric magnetic elds.

Web1.7. ORBITS IN AXISYMMETRIC POTENTIALS 23 1.7 Orbits in axisymmetric potentials We have seen above that empirically, most galaxies are not spherically symmetric, but rather have flattened disks or ellipsoidal shapes. For many of these more general potentials, azimuthal symmetry and also up-down symmetry (z −z) are still fine approximations. WebThis paper presents an efficient and accurate boundary element method (BEM) for the elastic analysis of axisymmetric problems in vertically non-homogeneous solids without or with cavity. This BEM uses the fundamental solution of the elastic field in a multilayered elastic solid induced by the body force uniformly concentrated at a circular ring.
WebOct 28, 1998 · The general formulation for the radiation force on a spherical object in an axisymmetric acoustic field is provided. The sphere is described in general by three parameters: its density, compressional wave speed, and shear wave speed.
