Papers that have already appeared in print may not be available here because of copyright considerations, but I can send reprints on request.
Some publishers have policies that allow for the web posting of preprint versions of articles that have appeared in print. In such cases, I try to leave the pre print version up on my web page. In each case I've also included a link to the official published version of the paper- if your institution has a subscription to the journal, then you should be able to get the published version of the paper. If your institution doesn't have a subscription to the journal, then you may also be able to get the paper through interlibrary loan. If this fails, you can contact me directly to obtain a reprint.
The ROMEO web site is a very useful source of information on Publisher's policies.
You can read more about our research group's work on landmine detection and remediation at the group's website.
All of the files here are now in Adobe PDF format. These can be viewed with the Adobe Acrobat reader or with Ghostview. Some of the files have been converted from old postscript files and there may be problems with the conversion. Please contact me if you need the original postscript files.
