The Strategic Defense Initiative (SDI), and subsequently the Ballistic Missile Defense Organization (BMDO) and the Missile Defense Agency (MDA) of the U.S. Department of Defense (DoD), have motivated NIST's work developing calibration methods and standards for space-based sensors used in missile

Accelerated Weathering Laboratory: Metrology and Technology Transfer

Ongoing
Objective - To maintain, improve and expand capabilities at the NIST Accelerated Weathering Laboratory (AWL) to conduct safe, accurate and traceable aging experiments, develop materials degradation databases, and to transfer the SPHERE technology to industrial stakeholders. What is the new technical

Accelerator Facilities

Ongoing
The Division's accelerator facilities continue to support a broad range of research efforts in the areas of industrial and medical dosimetry, homeland security, radiation-hardness testing and materials-effects studies. Topics of research during this reporting period included: (1) a broad-energy
thermal converter

AC-DC Difference

Ongoing
The use of thermal converters for ac voltage metrology was introduced by Frank Hermach at NIST in 1952. The basic thermal converter is a thermoelement, consisting of a thermocouple positioned at the midpoint of a heater wire, enclosed in an evacuated bulb. The thermoelement senses the heat generated
The NIST Acoustic Thermometer

Acoustic Techniques in Fluid Metrology

Ongoing
In collaboration with NIST's Chemical Sciences Division, we use photoacoustic resonators for continuous monitoring of the CO2 concentration in ambient air from a tall building rooftop; (see Fig. 2) [ 1] for measuring the optical properties of particles (e.g. soot) in air that affect the energy
Acoustic Thermometer

Acoustic Thermometry

Completed
Data from the NIST acoustic thermometer will form an improved basis for the equations used with platinum resistance thermometry, which is the primary mechanism to disseminate accurate temperature standards. Objective: To obtain measurements of thermodynamic temperature in the range between 273 K and

Actionable Intelligence

Ongoing
A large portion of this project involves a collaboration with the Engineering Laboratory’s (EL) Model-based Enterprise program, specifically with the Knowledge Extraction and Application for Manufacturing Operations project. This collaboration has focused on the analysis of maintenance work order

Activated Carbon and FGD Gypsum Standard Reference Materials

Completed
The role of mercury in the environment is now receiving close scrutiny because ultimately it can bioaccumulate as alkyl mercury in seafood with subsequent risk to human health through trophic transfer. Many industrial sources of mercury have been effectively reduced in recent years, but atmospheric

Activities in Extended Videos Evaluation

Ongoing
The National Institute of Standards and Technology (NIST) developed the Activities in Extended Video (ActEV) evaluations series to support the needs of the Intelligence Advanced Research Projects Activity (IARPA) Deep Intermodal Video Analytics (DIVA) Program. An activity for ActEV evaluation is
