The National Institute of Standards and Technology (NIST), Systems and Software Division, sponsored a Users’ Forum on the Application Portability Profile (APP) and Open System Environment (OSE) at NIST in May. This forum was the fifteenth in a continuing semiannual series on the NIST APP and its application to OSE. The APP Users’ Forums are designed to provide users and providers with the oppor...

The purpose of this NIST-initiated workshop was to provide an opportunity for U.S. discretepart manufacturing companies which see potential benefit from improved NIST research and services in areas of interest to them to make needs known such that NIST can address them, in particular to identify specific needed measurement-andstandards support from NIST which is not currently being provided or ...

A comparison has been made of the air-kerma standards for low-energy x rays at the National Institute of Standards and Technology (NIST) and the Physikalisch-Technische Bundesanstalt (PTB). The comparison involved a series of measurements at the PTB and the NIST using the air-kerma standards and two NIST reference-class transfer ionization chamber standards. Results are presented for the refere...

NIST Statistical Test Suite is an important testing suite for randomness analysis often used for formal certifications or approvals. Documentation of the NIST STS gives some guidance on how to interpret results of the NIST STS but interpretation is not clear enough or it uses just approximated values. Moreover NIST considers data to be random if all tests are passed yet even truly random data s...
