Hi everybody, Sometimes I find references to PTTI proceedings. Where can I find these documents? I had a look at the PTTI website http://tycho.usno.navy.mil/ptti.html but I didn't find some of them! Thanks again for helping me. Bye. Michelangelo.

Michelangelo, Recent PTTI papers are online or available on CD from USNO. There's a nearly up-to-date index at: http://tycho.usno.navy.mil/ptti/index.html Program and abstracts are at: http://tycho.usno.navy.mil/ptti.html Papers from the last few conferences are online with URL's that look like this (just change the year and paper number): http://tycho.usno.navy.mil/ptti/ptti2003/paper35.pdf Older years were hardcopy only and available at such places like metrology laboratory, T & F company, and University libraries. I have a partial set here and might be able to make a copy if there's a particular article you're looking for. Contact me off-line. If anyone has more information on this topic I'd like to know too. Perhaps someday they'll all be scanned (like IEEE did for FCS papers) or available on Google. Occasionally I put copies old papers at: http://www.leapsecond.com/history/ /tvb ----- Original Message ----- From: "TwoSpades" <michelangelo.albertazzi@gmail.com> To: <time-nuts@febo.com> Sent: Thursday, October 27, 2005 08:43 Subject: [time-nuts] PTTI Hi everybody, Sometimes I find references to PTTI proceedings.
