On the other hand, according to the 2006 NIST Special Publication 800-88 ( p. 7 ): " Studies have shown that most of today ’ s media can be effectively cleared by one overwrite " and " for ATA disk drives manufactured after 2001 ( over 15 GB ) the terms clearing and purging have converged.

The BRLESC I ( Ballistic Research Laboratories Electronic Scientific Computer ) was a first-generation electronic computer built by the United States Army's Ballistics Research Laboratory ( BRL ) at Aberdeen Proving Ground with assistance from the National Institute of Standards and Technology ( NIST ), and was designed to take over the computational workload of EDVAC and ORDVAC, which themselves were successors of ENIAC.

The canonical work in the field is the NIST publication edited by Abramowitz and Stegun, a 1000-plus page book of a very large number of commonly used formulas and functions and their values at many points.

Recent developments in small scale CNC have been enabled, in large part, by the Enhanced Machine Controller project from the National Institute of Standards and Technology ( NIST ), an agency of the US Government's Department of Commerce.

NIST replaced these codes with the more permanent GNIS Feature ID, maintained by the U. S. Board on Geographic Names.

In 1992, the US Department of Defense along with the National Institute of Standards and Technology ( NIST ), cosponsored the Text Retrieval Conference ( TREC ) as part of the TIPSTER text program.

The NIST National Institute of Standards and Technology vulnerabilities database, US-CERT, rates traditional mainframes such as IBM zSeries, Unisys Dorado and Unisys Libra as among the most secure with vulnerabilities in the low single digits as compared with thousands for Windows, Linux and Unix.

In addition, NIST partners with 1, 400 manufacturing specialists and staff at nearly 350 affiliated centers around the country.

NIST works in conjunction with the Technical Guidelines Development Committee of the Election Assistance Commission to develop the Voluntary Voting System Guidelines for voting machines and other election technology.

New versions of PGP applications use both OpenPGP and the S / MIME, allowing communications with any user of a NIST specified standard.

Official policies about the use of these prefixes vary slightly between the Bureau International des Poids et Mesures ( BIPM ) and the American National Institute of Standards and Technology ( NIST ); and some of the policies of both bodies are at variance with everyday practice.

For instance, the NIST advises that "… to avoid confusion, prefix symbols ( and prefixes ) are not used with the time-related unit symbols ( names ) min ( minute ), h ( hour ), d ( day ); nor with the angle-related symbols ( names ) ° ( degree ), ′ ( minute ), and ″ ( second ).

The BIPM ’ s position on the use of SI prefixes with units of time larger than the second is the same as that of the NIST but their position with regard to angles differs: they state " However astronomers use milliarcsecond, which they denote mas, and microarcsecond, µas, which they use as units for measuring very small angles.

NIST states ; " Prefix symbols may be used with the unit symbol ° C and prefixes may be used with the unit name ' degree Celsius '.

However, ANS X9. 52 specifies directly, and NIST SP 800-67 specifies via SP 800-38A that some modes shall only be used with certain constraints on them that do not necessarily apply to general specifications of those modes.

NIST 800-57 recommends lengths of 2048 ( or 3072 ) for keys with security lifetimes extending beyond 2010 ( or 2030 ), using correspondingly longer N. FIPS 186-3 specifies L and N length pairs of ( 1024, 160 ), ( 2048, 224 ), ( 2048, 256 ), and ( 3072, 256 ).

NIST won praises from the cryptographic community for the openness and care with which they ran the standards process.

The cryptographic community recognized the need for dedicated integrity assurances and NIST responded with HMAC, CMAC, and GMAC.

As defined by NIST, " Traceability of measurement requires the establishment of an unbroken chain of comparisons to stated references each with a stated uncertainty.

A National Institute of Standards and Technology ( NIST ) investigation of the fire, using computer simulations with FDS and a mock-up of the stage area and dance floor, concluded that a fire sprinkler system would have contained the fire long enough to give everyone time to get out safely.

* NIST simulations of the fire: without sprinklers ; with sprinklers
