Spherical Harmonic Amplitudes From Grid Data
نویسنده
چکیده
The problem of resolving spherical harmonic components from numerical data defined on a rectangular grid has many applications, particularly for the problem of gravitational radiation extraction. A novel method due to Misner improves on traditional techniques by avoiding the need to cover the sphere with a coordinate system appropriate to the grid geometry. This paper will discuss Misner’s method and suggest how it can be improved by exploiting local regression techniques.

Spherical Harmonic Decomposition on a Cubic Grid
A method is described by which a function defined on a cubic grid (as from a finite difference solution of a partial differential equation) can be resolved into spherical harmonic components at some fixed radius. This has applications to the treatment of boundary conditions imposed at radii larger than the size of the grid, following Abrahams, Rezzola, Rupright et al. [1]. In the method describ...
متن کاملAn approach for spherical harmonic analysis of non-smooth data
Amethod is proposed to evaluate the spherical harmonic coefficients of a global or regional, non-smooth, observable dataset sampled on an equiangular grid. The method is based on an integration strategy using new recursion relations. Because a bilinear function is used to interpolate points within the grid cells, this method is suitable for non-smooth data; the slope of the data may be piecewis...
متن کاملJoint source localization and separation in spherical harmonic domain using a sparsity based method
In this paper, we address the problem of source localization and separation using sparse methods over a spherical microphone array. A sparsity based method is developed from the observed data in spherical harmonic domain. A solution to the sparse model formulated herein is obtained by imposing orthonormal constraint on the sparsity matrix. Subsequently, a splitting method based on bregman itera...
متن کاملDesign of a Digital Voltage Controller in Single-Phase Grid-Connected Renewable Converters
Power decoupling of pulsating grid side power from constant source side power is one of the paramount issues in single phase-phase grid-connected renewable systems. The principal aim of such systems is the decrease of the capacitance of the decoupled capacitor. However, this causes some problems such as an increase in the total harmonic distortion (THD) of injected current to the grid and bus v...
متن کاملBoundary conditions in linearized harmonic gravity
We investigate the initial-boundary value problem for linearized gravitational theory in harmonic coordinates. Rigorous techniques for hyperbolic systems are applied to establish well-posedness for various reductions of the system into a set of six wave equations. The results are used to formulate computational algorithms for Cauchy evolution in a 3-dimensional bounded domain. Numerical codes b...
