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 provide reasonable assurance that its interagency agreements are complete, accurate, and constitute a binding legal agreement, create, document, and implement a robust fiscal and legal review process for interagency agreements.
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.
For each NIST
force calibration report, this measurement uncertainty is given as the expanded uncertainty, U, which is calculated in accordance with NIST
Technical Note 1297, "Guidelines for Evaluating and Expressing the Uncertainty of NIST
Measurement Results" .
Despite the loss of about a quarter of the transmitters, the NIST
team is reporting its initial findings, some of them striking.
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.
Silicon micromachining methods currently being developed at NIST
can be used to make vapor cells with dimensions well below 1 m[m.
To produce standard bullets, the NIST
team first machined pieces of a copper alloy into bullet shapes.
develops Federal Information Processing Standards (FIPS) when there are compelling Federal government requirements, such as for security and interoperability, and there are no acceptable industry standards or solutions.
scientists used the data to generate curves of electric field versus temperature at constant current and magnetic field.
Projects to make fountain-type clocks adapted to zero gravity for the International Space Station are also under way in France and at NIST
This service is being implemented within the National Vulnerability Database (NVD) at NIST
, based on Red Hat's recommendation.
When testing is completed, the laboratory submits the results to NIST
