The major NIST atomic spectroscopy data tables and the new NIST atomic spectra database (ASD) on the Internet are briefly reviewed. The need for critical
This paper gives a short history of the development of the accelerometer calibration services at NBS/NIST from the mid-1950s to 1996. Many people were involved
The performance of the multiconfiguraton Dirac-Fock (MCDF) method in calculating transition probabilities of atoms is reviewed. In general, the MCDF wave
In order for intranets to reach their full potential, access control and authorization management mechanisms must be in place that can regulate user access to
The RBAC metaphor is powerful in its ability to express access control policy in terms of the way in which administrators view organizations. The functionality
Role based access control (RBAC) is attracting increasing attention as a security mechanism for both commercial and many military systems. Much of RBAC is

A number of 150 mm apertures in 250 mm diameter plano-concave optics with figure errors of a few nm were carefully tested using phase measuring interferometry
The optimization of mixture proportions for high-performance concretes, which contain many constituents and are often subject to several performance constraints
NIST and a consortium of companies are organizing a public demonstration of the features of IEEE P1451, a Draft Standard for a Smart Transducer Interface for
The dynamic nature of the Web poses problems for usability evaluations. Development times are rapid, changes to Web sites occur frequently, often without
We provide a progress report on the critical evaluation of transition probabilities for Na to Ca (Z-11-20), which are to replace the 30 year old NIST/AIP/ACS
