Could someone be kind enough to see if they can run some of
these educational Java applets here

Some of them do run ok for me, but few do not. Here is example
of the ones that do NOT run for me:

http://www.jhu.edu/~signals/bandwidth/index.html
http://www.jhu.edu/~signals/sensitivity/index.htm
http://www.jhu.edu/~signals/robust2/index.html

and few more. The above give me error:

Just wanted to know if the problem is on my end.

I did send email, but I think these applets are not being
maintained any more (as so many applets are on the web these days,
many seem not to work any more. Too bad).

There is no source code, so I can't even try to download them
and try to fix.

My configuration is this: windows 7, Firefox 11, Java 7
update 3. In the browser, I see Java plugin 10.2.1.255 for Mozilla
enabled.

If you try it, and it works for you, can you post
what configuration you have?

Thank you.

They don't run for me, Win XP, SP3, Java 7_03, Firefox 11.0. After
clicking on the "Error. Click for details" I get a dialog that says
Width(0) and Height(0) cannot be <= 0. Clicking on the Details button
of that dialog gets me the Jave Error Console but no errors are listed.
