A significant portion of NIST scientific outputs lie outside these two categories.
Recommendation: To improve the management of NIST interagency agreements and provide reasonable assurance that NIST is efficiently using its resources and complying with applicable fiscal laws, the Secretary of Commerce should direct the NIST Director to comply with fiscal law, NIST should review its close-out policies regarding returning unearned funds to client agencies and adjust its accounts accordingly.
The record-low uncertainty of the NIST clock opens the door to ultraprecise tests of foundations of physics, including relativity and the steadiness of the so-called fundamental constants (SN: 5/14/05, p.
The expanded uncertainty U is reported in units of the transducer response, providing the uncertainty in the response values calculated from the calibration equation yielded by the NIST calibration measurements.
Two months after the New Orleans experiment, the NIST engineers were in Philadelphia for the felling of Veterans' Memorial Stadium.
In addition, off-site laser sources can be used in conjunction with a portable beamsplitter/attenuator system designed and built by NIST to perform these measurements.
To produce standard bullets, the NIST team first machined pieces of a copper alloy into bullet shapes.
By participating in the NIST contest, they agreed to make their algorithm freely available.
NIST's results will be used by Lawrence Livermore National Laboratory, which will test CICC samples at the Plasma Physics Research Center in Villigen, Switzerland, with current up to 100 000 A and magnetic fields up to 12 T, while controlling the mass-flow rate of the coolant.
The use of cold atoms represents "a fundamental change in the way we build atomic clocks," says NIST's Steven Jefferts, also in Boulder.
In October 2003, NIST's Cryptographic Module Validation Program (CMVP) reached a significant milestone by issuing the 100th Advanced Encryption Standard (AES) Algorithm Validation Certificate for hardware implementation of AES named 7814-W.
Toward that goal, researchers at the National Institute of Standards and Technology (NIST) in Gaithersburg, Md., report that by weighing the kilogram against an electromagnetic force, they have measured a fundamental physical quantity, known as the Planck constant, with twice the precision of previous experiments.
