If you are having trouble seeing the
figures in this site it is due to a browser incompatibility problem
that I have not been able to fix. This pages on this site were
created using Mathtype (by Design Science) and published using
Microsoft Frontpage, and one of these programs (I don't know which)
produces web pages that can only be viewed using fairly recent
versions of Internet Explorer. Note that you must allow
Internet Explorer to run ActiveX controls to see the figures and
equations.
