I would love to take a look at this but the links to the paper at the IEEE are dead. My Google search just turned up others looking for the same paper. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
