Technical Idea: To

Performance Criteria Development

Ongoing
Objective: To advance component-level seismic performance criteria in current design standards by conducting focused experimental tests and analytical studies. What is the Problem? Performance-based seismic engineering methodologies require a thorough and accurate understanding of component-level

Performance of Human-Robot Interaction

Ongoing
Objective To deliver a suite of datasets, benchmarking tools, test methods, protocols, metrics, standards, and information models to enable effective, human-robot collaboration in manufacturing, and advance interactive robot technologies to facilitate the safe and efficient teaming of people and

Performance Metrics for Direct Air Capture of Carbon Dioxide

Ongoing
Sorbents in Direct Air Capture (DAC) are exposed to the atmosphere, where they adsorb CO2 then are isolated from atmosphere, the CO2 is driven off by heating or pulling vacuum, refreshing the sorbents. This adsorption-refresh cycle depends not only on the competitive adsorption of CO2 with the other

Performance Metrics for Proteomics

Ongoing
Intended Impact Proteomics experiments designed to identify protein markers specific to a particular disease or disease state rely on repeatable identification of proteins within a control set. Repeatability provides statistical assurance that clear differences between two sets (e.g. sick vs

Ongoing
Objective: To produce validated computational tools and technical guidance enabling the development of performance­-based standards for the cost-effective fire resistance design and assessment of structures. What is the new technical idea? The focus of this project is to develop a comprehensive

Performance-Based Seismic Engineering (PBSE) for New Buildings Project

Ongoing
Objective: To develop a measurement science tool by FY 2016 that is capable of directly, accurately, and efficiently simulating the initiation and progression of structural collapse, and to develop a methodology for quantifying acceptance criteria limits found in the ASCE/SEI 41 Standard [1] through

Personal Body Armor

Completed
To quantify the impact of mechanical degradation on ballistic fibers, NIST developed a novel device for controlled folding of yarns and woven fabrics. In addition, we developed test protocols that employ single fibers to assess the effect of folding using a recently developed modified single fiber

Phase and Amplitude Noise Calibration Services

Ongoing
The primary responsibility of the Phase Noise Metrology Group is to develop and provide calibration services for industrial, military, and commercial organizations to support the core mission of NIST. The PM and AM noise measurements require traceability and certification of devices such as phase

Phase and Amplitude Noise Metrology

Ongoing
The group provides high-precision measurement of electromagnetic signals in the radio-frequency, microwave and optical range. These measurements include phase noise, amplitude noise and perturbations due to vibration and temperature. Such precision measurements support high-value applications such

The Photoforce Project

Ongoing
Traditional power meters measure the power of a laser beam by absorbing its energy. Radiation pressure (photon momentum) permits the measurement of a beam’s power by “absorbing” its momentum and reflecting its energy. Light reflecting from a mirror causes a force that is proportional to its optical

Photometry

Ongoing
The development of revolutionary energy-efficient solid-state lighting (SSL) products has sparked the need for new performance metrics and measurement methods to address their unique construction and operating conditions. NIST has been working closely with the U.S. Department of Energy (DOE)

Photon Absorbed-Dose-to-Water Primary Standards

Ongoing
Modeling of accumulated-dose dependence in the heat defect of H2/O2 exhibits expected peak behavior in qualitative agreement with experiment, and is being further refined for purposes of reducing the associated relative uncertainty from its present value of 0.3 %. Studies to quantify the possible

Photon Drag in Metal Films

Ongoing
The photon-drag (PD) effect is the rectified electrical current in a medium generated by radiation pressure. That is, the optical force delivered to an illuminated metal results in a measurable voltage across the film (Figure, left). For decades, this effect in metals has been understood in terms of

Photonic Dosimetry

Ongoing
With this effort, NIST is responding to industry needs for traceable, measurement solutions that can resolve spatial variations of absorbed dose at the level of individual components on a silicon wafer or bacteria on surgical instruments. Presently, there is only limited traceability to national

Photonic Quantum State Imaging Metrology

Ongoing
Fundamental understanding of quantum behavior of single molecules, which is a favorable candidate for quantum information processing technologies, has advanced gradually, relying on empirical studies mostly. This requires a measurement platform to study fundamental quantum characteristics in single
