In November 2000, NIST hosted a workshop on Measurement Traceability for Clinical Laboratory Testing and In Vitro Diagnostic Devices. One of the driving forces was the new European Community (EC) In Vitro Diagnostic Devices (IVDD) directive that requires

A new type of capacitance standrd based on counting electrons has been built. The operation of the standrd has already given very promising results for the determination of the value of a cryogenic vacuum-gap capacitor. The new capacitance standard

A robotic HMMWV (a.k.a. "humvee") drives autonomously offroad at speeds up to 35 km/h (10 m/s, 20 mph). Key features of the implementation that enable driving at these speeds are (1) planning the next 20 m with dynamically feasible trajectories, and (2)
This is a preliminary study of lead and bismuth selinides and tellurides to determine the usefullness of these materials as Pb and Bi standards for quantitative microanalysis. Precautions were taken during sample preparation procedures to reduce the
This paper analyzes the meaning of intelligence within the domain of intelligent control. Because of historical reasons, there are varying and diverse definitions of what constitutes an intelligent control system. Due to the multidisciplinary nature of
This is a review of the current status of microanalysis standards at NIST -what is presently available, what will soon be available, and what might be available in the future. Many of the standards issued in the past such as Cartridge Brass (SRM 478), Fe-3
The U.S. Federal Government has a strong role in metrology R&D in the U.S because of its importance to the nation's economy and the Constitutional authority given to the National Institute of Standards and Technology (NIST). However, pressures to maintain
Commonly used primary calibration techniques for the measurement of liquid and gas flows are described. The techniques described include: static gravimetric and dynamic gravimetric methods for both gases and liquids, liquid piston displacement provers
The certification of a polyethylene standard reference material, SRM 2886, is described. The Mw of SRM 2886 by light scattering was determined to be 87.0x10+3 g/mol with a sample standard deviation of 2.4 x10+3 g/mol. A combined expanded uncertainty for

A follow-on to Measures for Progress by Rexmond C. Cochrane, this work covers the history of the National Bureau of Standards (NBS) from 1950-1969. While the book focuses on technical work, the management and administration of the Bureau are also discussed
This document provides a description of the small and medium range gas flow calibration facilities at the National Institute of Standards and Technology (NIST), Fluid Flow Group, as reported in NIST Special Publication 250 for Test Nos. 18010C-18040C and
Speech presented to the Japanese Committee for Clinical Laboratory Standards (JCCLS). The National Committee for Clinical Laboratory Standards (NCCLS) and JCCLS are partners and share the common goal of improving the health care of our nations and the
