Usability and Public Safety Communications Research

Completed
First responders in public safety respond to emergency incidents to serve and protect their communities. The voices of first responders have often not been taken into consideration, especially when technology is developed for them but not with them. The National Institute of Standards and Technology

Usability Standards

Ongoing
We participate on the ISO/IEC JTC 1/SC 7 and ISO/TC 159/SC 4 as the WG28 Joint Working Group, US delegation co-convener, to develop standards for usability documentation. This family of standards provide a definition of the type and scope of formats and the high-level structure to be used for

Usability Testing

Ongoing
Usability testing refers to evaluating a product by testing it with representative users performing representative tasks. The goal is to identify any usability problems by collecting quantitative (e.g., time on task, errors and successful completion rates) and qualitative (e.g., comments, likes or

AI User Trust

Ongoing
The Visualization and Usability Group’s AI User Trust project provided foundational work for our new AI User Trust Measurement research, and continues to inform our larger Human-Centered AI program. Please read more about our current work on those pages. The information that follows is maintained

USGv6 Program

Ongoing
OMB has directed [ OMB-2020, OMB-2010, OMB-2005] the National Institute of Standards and Technology (NIST) to develop the technical infrastructure (standards and testing) necessary to support wide-scale adoption of IPv6 in the US Government (USG). In response, NIST developed a technical standards

Using AI to Determine Structure-Property Relations in Materials

Ongoing
The Material Measurement Lab at NIST employs artificial intelligence for the prediction and discovery of materials characteristics. Our applications of artificial intelligence (AI) accelerate materials research as well as help the community learn about AI's capabilities and gain confidence in

Using Geodesics in Cell Cytometry

Ongoing
This project involves image cytometry, mathematics and statistics. Understanding cellular responses to stimuli, such as pharmaceuticals or environmental toxins and discovering correlations between cellular responses and the cell phenotype are applications motivating this work. Change in shape is a

Using Quantum Information for Thermodynamics

Ongoing
We re-envision thermodynamics using the mathematical and conceptual toolkit of quantum information theory. We call this research “quantum steampunk,” after the steampunk genre of art, literature, and film that juxtaposes Victorian settings with futuristic technologies. Leveraging quantum

USNWG Field Reference Meters: Coriolis Mass Flow Meters

Ongoing
Customers and businesses alike rely on metering systems to monitor and deliver their liquid-based commercial products (including a range of gas and fuels) consistently over time and across a range of locations. Weights and measures officials use several well-acknowledged field test standards to

Validating A.I. Pipelines for Analysis of Live Cell Image Data

Ongoing
We are exploring methods for very high-speed cell image data collection, which is enabling the repeated sampling of thousands of cells every 2 minutes. Rapid sampling allow us to observe dynamic processes in cells (such as cell division) on a relevant time scale. Such rates of sampling allows us to

Validation of ASCE 41 Procedures in PBSE

Completed
Objective - The objective of this study is to advance first-generation performance-based seismic engineering (PBSE) methods by assessing the performance of a set of code-compliant buildings using ASCE/SEI 41 methodologies. This study focuses on steel buckling-restrained braced frames (BRBFs) and

Validation of Density Functional Theory for Materials

Completed
A variety of systems will be considered in this work: Pure and alloy solids will be studied using periodic DFT methods with three distinct crystal structures that are relevant to the widely-used CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) method. This study emphasizes the

Vapor Sampling in the Field

Ongoing
Breath sampling of cannabis users. Several versions of breath collection devices are being marketed for the detection of THC (delta-9-tetrahydrocannabinol) in the breath of cannabis users. THC is not directly correlated to intoxication but may indicate recent smoking or vaping. THC and other

Vapor Sampling to Support Public Safety and Forensics

Ongoing
Vapor pressures of unstable, reactive compounds. Over the last decade, our group has investigated a variety of low-volatility compounds including taggants (found in explosives), biofuels, terpenes and cannabinoids. Dynamic vapor microextraction (DVME), developed at NIST, is a small-volume dynamic

Vehicular Network System

Ongoing
The Middle Class Tax Relief and Job Creation Act of 2012 (H.R. 3630) appropriated $7 billion for the establishment of a nationwide interoperable public safety broadband network under FirstNet, an independent authority in the National Telecommunications and Information Administration (NTIA). FirstNet

Ventilation and Indoor Air Quality in High-Performance Buildings

Ongoing
Objective: To develop tools to quantify and verify high-performance IAQ in buildings, provide input data to improve usability of the tools including building models, develop methods needed to support and verify the applicability of these tools to improving the effectiveness of high-performance

Ventilation Performance for Novel Sustainability and Resilience Challenges

Ongoing
Objective: To develop tools, metrics, and data to enable sustainable, resilient, high-performance building and ventilation system design and operation in response to current and future challenges. Also, to develop a methodology to evaluate potential changes to ventilation and IAQ standards so their

Vertebrate Endocrine Metrology in Non-Traditional Matrices

Ongoing
NIST collaborates with stakeholders to develop techniques for measuring hormone levels as part of animal health assessment. The process of capturing and transporting animals before sampling can induce stress, which may alter the hormone levels in the bloodstream. Therefore, the collection of blood

Video Analytics

Ongoing
Active evaluations/projects include: Activities in Extended Videos: The ActEV evaluation seeks to evaluate robust automatic activity detection algorithms for a multi-camera streaming video environment. ActEV will address activity detection for both forensic applications and for real-time

Virtual Cement and Concrete Testing Laboratory

Ongoing
The intended impact of this project is to enable a rapid and convenient virtual computing environment for evaluating and optimizing cementitious materials. Substantial savings in time, materials (purchase and disposal), human resources, and money can be achieved by reducing the number of physical

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
