Virtual Measurements

Ongoing
Intended Impact When engineering data, such as for reactive-chemical hazards, are obtained using quantum chemistry, the lack of associated uncertainties means that the reliability of the data is poorly known. Safety thus requires a skeptical view, often leading to expensive over-design. Objective

Vision science

Ongoing
NIST has been providing physical measurement standards in photometry and colorimetry for many years. However, the definitions of photometric and colorimetric units and standards are often questioned or found to be insufficient for modern lighting technologies. Large discrepancies between

Visualization

Ongoing
Current visualization technology provides a full range of hardware and techniques from static two-dimensional plots, to interactive three-dimensional images projected onto a monitor, to large screen fully immersive systems allowing the user to interact on a human scale. Immersive virtual reality

Vitamin D Metabolites Quality Assurance Program (VitDQAP)

Completed
Interlaboratory comparison studies of the VitDQAP supported the reliability of vitamin D measurements, including determination of 25-hydroxyvitamin D2, 25-hydroxyvitamin D3, and 3- epi-25-hydroxyvitamin D3 in human serum and plasma. Results from the comparison studies helped participants to make

Voting Systems Usability and Accessibility

Ongoing
The 2002 Help America Vote Act (HAVA) gave NIST a key role in helping to realize nationwide improvements in voting systems. NIST performs research that examines the role of human factors in the design and application of next generation voting systems, including assistive technologies for individuals

Wastewater Surveillance

Ongoing
NIST is partnering with the Department of Homeland Security Science and Technology Directorate (DHS/S&T) to develop documentary standards and reference materials to support an enduring capability in wastewater surveillance. Ongoing activities include: Development of a research grade test material

Water Measurement Science

Ongoing
Measurements and Standards for Contaminants in Water Accurate measurements of contaminants in water are critical to ensure the usability and safety of our water supplies. NIST has developed Standard Reference Materials (SRMs) for validating or calibrating methods for inorganic contaminants including

Waveform Measurements of Radars Operating in the 3.5 GHz Band

Ongoing
This NASCTN effort is coordinated with the Department of Defense (DOD), and the results of this project will support the spectrum regulators as they develop a certification process for Spectrum Access Systems (SAS) and the associated Environmental Sensing Capability (ESC) that may be deployed in

Waveform Metrology Project

Ongoing
Optical measurement techniques: NIST uses the electro-optic sampling (EOS) technique to measure the vector response of photodiodes and provide phase traceability for commercial instrumentation, such as large-signal network analyzers, lightwave component analyzers, vector signal analyzers

WEBAPI

Ongoing
Measurement is difficult due to the complexity of the underlying technologies being addressed. In addition, measuring conformance in web applications requires large test sets covering a wide a range of standards. Currently, W3C WEB Applications working group members are responsible for developing

WebFF: Force-field repository for organic and soft materials

Ongoing
WebFF is an open and extensible force-field (FF) repository, designed to support the Materials Genome Initiative (MGI) for organic and related soft materials. The repository is built using the NIST Materials Data Curation System (MDCS) which supports ontology based database descriptions using XML

Wide-area Monitoring and Control of Smart Grid

Completed
Objective: To develop and verify innovative sensing systems and take full advantage of existing ones such as smart meters, PMUs, Merging Units (Mus), and other intelligent electric devices (IEDs), to enable greater electric grid resiliency, reliability, flexibility, and sustainability through

Wireless Access Networks

Completed
MIMO is a most attractive multi-antenna technique that has been adopted by many emerging wireless communication standards, such as Wireless LAN (WLAN) and fifth generation wireless (5G), owing to the achievable antenna array, multiplexing, and diversity gain. In order to improve link reliability

Wireless Coexistence

Ongoing
What is Wireless Coexistence? Wireless coexistence is the capability of multiple wireless devices and services in the same geographical area to access the same RF spectrum band simultaneously without causing harmful interference to each other. In other words, can they all operate successfully and

Wireless M2M Network For Power Grid

Completed
In conventional transmission systems, wired sensor technologies are largely used in power plants and substations to control and monitor critical parameters. The distribution system does not normally have the support of any infrastructure network. Despite the fact that wired technologies offer a good
