This draft report was prepared by NIST staff at the request of the Technical Guidelines Development Committee (TGDC) to serve as a point of discussion at the Dec. 4-5 meeting of the TGDC. Prepared in conjunction with members of a TGDC subcommittee, the report is a discussion draft and does not represent a consensus view or recommendation from either NIST or the TGDC. It reflects the conclusions...

The Shuttle Solar Backscatter Ultraviolet (SSBUV) programme uses 1000 W, quartz-halogen, tungsten coiled ® lament (FEL) lamps as the primary radiometric calibration source in the 250 nm to 405 nm wavelength region. The National Institute for Standards and Technology (NIST) recommends using the product of a ® fth-order polynomial and a Planck function as a ® tting function for interpolating the ...

PAST PRECISION MEASUREMENT GRANT HOLDER WINS NOBEL PRIZE The 2001 Nobel Prize in Physics will be shared by two JILA fellows, Eric Cornell of NIST and Carl Wieman of the University of Colorado, and Wolfgang Ketterle of MIT for their work on Bose-Einstein condensation of atoms. In 1979, Carl Wieman, then at the University of Michigan, was awarded a NIST Precision Measurement Grant. This brings to...

Automatic evaluation metrics for Machine Translation (MT) systems, such as BLEU and the related NIST metric, are becoming increasingly important in MT. Yet, their behaviors are not fully understood. In this paper, we analyze some flaws in the BLEU/NIST metrics. With a better understanding of these problems, we can better interpret the reported BLEU/NIST scores. In addition, this paper reports a...

The development of atomic frequency standards at NIST is discussed and three of the key frequency-standard technologies of the current era are described. For each of these technologies, the most recent NIST implementation of the particular type of standard is described in greater detail. The best relative standard uncertainty achieved to date for a NIST frequency standard is 1.5×10(-15). The un...

Efficient and consistent simulation data management is indispensable and a challenging problem to be solved in modeling manufacturing and business processes. An extensible markup language (XML) based simulation interface specification is being developed by the National Institute of Standards and Technology (NIST). The proposed NIST document contains a prototype generic simulation data specifica...

The National Institute of Standards and Technology operates a cesium fountain primary frequency standard, NIST-F1, which has been contributing to International Atomic Time (TAI) since 1999. During the intervening 11 years, we have improved NIST-F1 so that the uncertainty is currently 16 0 3 10 , f f     dominated by uncertainty in the blackbody-radiationinduced frequency shift. In order to ...
