Dear All,
I had some interactive computer programs and lecture notes on my geocities site which has now been closed (Yahoo! closed the free service). However, for now I have moved these to a new site and the resoruces are still available at no cost. The new addresses are ilanko.org/engineering ilanko.engineering/vibration
I will try to put more notes and programs on this site.
Regards, S. Ilanko
