Looking at the price of Dell's ECC RAM: you can probably live with some bit error probabilities in the 2e-11/bit/hr range (which I think is what's estimated for modern RAM) for noisy data without any problem, so ECC possibly isn't important here (but I don't know your operational requirements! So take with a grain of salt).

Description of routine maintenance and estimate of ongoing maintenance costs. The proposal shall be limited to 10, 8 ½" by 11", 12 pt. font pages not including the cover.

As for the Shera design: The red line IS an a bit too optimictic estimation for this case.

However the sampling rate has to be sufficiently high (well above the Nyquist limit) to allow this without using WSK interpolation to estimate the signal value between the samples. > thanks, it's always fun to read your comments > ws > > ************* Bruce > ----- Original Message ----- From: "Bruce Griffiths" > > To: "Discussion

I believe the 2 ms/day / century estimate we use is one such measurement. For more on earth rotation rate, UTC and leap seconds see https://www.ucolick.org/~sla/leapsecs/dutc.html Surely in the literature there is a pile of information or speculation regarding all the rotational energy in the universe.

It's important to know that NASA, in general, does not do "reliability calculations" in a MIL-HDBK-217 way - there's no stacking up of individual part reliabilities to get an estimated system MTBF. This is historical - NASA typically builds "just one unit" (maybe 2 or 3) - so there's no chance to do life testing and build up statistics.
