Accelerator-based mass spectrometry measurement of long-lived radioisotopes,
applied to archeology, geophysics and meteoritics.
Scale-space and equation-error minimization approaches to problems in image
reconstruction and solution of partial differential equations.
Least-squares fitting data with experimental uncertainties in all
coordinates.
Fit to a hyperplane having only one dependent coordinate and any number of independent coordinates.
This work was done when I was a graduate student many years ago. It
was never published except as a tech report. Here is that tech
report in
PDF format,HTML format, or the original
LaTeX document.
Fit to a hyperplane having any number of dependent coordinates and any number of independent coordinates.
This work has been submitted to Applied Numerical Mathematics.
An expanded version of that paper is available in PDF format here.
