back to the original topic - An interesting subject for a thesis. There is quite a bit of testing, research and formulas. I have only skimmed through it, but it looks pretty cool.
Thanks, that is a very interesting link too. Actually, I vaguely remember hitting on it before, but at the time not looking closer. Lot's of interesting info there too though...
James Reilly is also on the list of acknowledgements of the article I pointed out, and well known for some other good research.
