RESEARCH ADVISORY COMMITTEE'S SUMMER SEMINAR
Judah Levine, Physics Laboratory, will present the second NIST Research
Colloquium--Summer Seminar on Friday, July 21 at 10:30 a.m. in Room 1107,
Building 1. His topic will be "Sending Time to the Masses."
ABSTRACT
The NIST Network Time Service responds to more than 25 million requests per
day for time in a number of different formats. Demand has grown
continuously since the service was started several years ago, and there is
no sign that this growth rate is slowing. Dr. Levine will discuss the
details of how this service is designed, with particular emphasis on the
statistical considerations that determine the accuracy that can be realized
using this system. In particular, he will explain the statistical
considerations that govern the very explicit tradeoff between the accuracy
that can be achieved and the cost of achieving it. Although he will focus
on these digital time services, the principles that he will discuss are
useful in other applications as well. He will talk briefly about applying
them to the construction of time scales in general and the procedure that
is used to define UTC(NIST) in particular.
