Point sources of elastic deformation: elementary sources, dynamic displacements

Detection of point sources

Photometry of individual sources requires an initial phase of detection. The detection process can be separated into two phases: (1) preprocessing of the image, and (2) actual detection, yielding a list of discrete sources. Given a distribution of background intensities, the probabilityof intensitydeviations for light sources as a result of the background can be calculated. Setting a maximum ac...

Bandmerging SIRTF Point Sources

1.1.3.) Produce a statistical summary that includes: (a.) counters for the spectral combinations produced, binned by brightest-band magnitude; (b.) mean position offsets and variances on both position axes for all band-pair combinations; (c.) chi-square values for all band-pair position discrepancies, binned by brightest-band magnitude. Items (b.) and (c.) will use only bandmerged sources with ...

Noncommutative point sources.

We construct a perturbative solution to classical noncommutative gauge theory on R3 minus the origin using the Groenewald-Moyal star product. The result describes a noncommutative point charge. Applying it to the quantum mechanics of the noncommutative hydrogen atom gives shifts in the 1S hyperfine splitting which are first order in the noncommutativity parameter.

Potentials and displacements for two theoretical seismic sources

Theoretical, P, S V, and SH displacement potentials and displacements for a double couple or point shear dislocation source and for a 'mixedquadrupole' source at any arbitrary orientation in an isotropic homogeneous elastic space are expressed as multiple integral and derivative operations on the source history in the time domain and their algebraic equivalent in the frequency domain. These sou...
