Paul Withers, PhD

Papers, projects, presentations, proposals, and piffle

Here are as many of my papers, projects, presentations, proposals, and piffle as I could find and put online. Many of the older ones lack appendices and some figures. Files are in PDF format. You'll probably need some kind of Adobe Acrobat Reader to look at them. Email withers@lpl.arizona.edu if you would prefer Postscript files or the original Word/LaTeX/Powerpoint documents.
