Data-Driven Network Optimization for Future Wireless Systems

Ongoing
Research Highlights AI Innovations in Spectrum Sharing for Wireless Networks With the increasing demand for wireless communication, efficient spectrum management has become essential. NIST is exploring the application of AI/ML techniques to optimize this area, particularly through solutions like

Decontamination of Biological Threats in Water Supplies

Completed
The outcome of the project was to provide the EPA with a technical resource document that could be used to guide emergency responders and for longer-term microbial decontamination of building water systems. This project was done in collaboration with the Building and Fire Research Laboratory (BFRL)

Deducing Prior Material Deformation from Simple Mechanics

Ongoing
Process-structure-property linkages suggest an opportunity to deduce processing from behavior. Simple imaging experiments provide rich sources of data. Can we deduce prior deformation? Scheme: Thin film plasticity Deform to some reference strain Unload Deform to test strain, image Deduce

Deep Learning for MRI Reconstruction and Analysis

Ongoing
The project is proceeding in three directions. Creating a new MRI reference artifact designed to assess geometric distortion using NIST’s MRI scanner. The artifact will be small enough to fit within the scanner with sufficient clearance to allow for variation in positioning within the scanner.
EUV optics degradation in space

Degradation of extreme-ultraviolet optics

Ongoing
The primary degradation process in EUVL tools and satellite instruments begins by the adsorption of water or carbonaceous molecules from the vacuum environment onto the optic surface. The optic is damaged if the molecule undergoes photon-stimulated decomposition before it can (reversibly) thermally

Department of Homeland Security Response Robot Performance Standards

Ongoing
The Intelligent Systems Division of the National Institute of Standards and Technology is conducting an ongoing project, sponsored by the Department of Homeland Security Science and Technology Directorate and the National Institute of Justice, to produce a comprehensive set of standard test methods
Illustration of Doppler thermometry

Deployable Doppler Thermometry

Ongoing
Accurate temperature measurements are essential to many industrial processes, including petrochemical or pharmaceutical production and nuclear power generation. Typical process control thermometers, such as resistance temperature detectors, are known to drift over time and degrade when subject to

Design and Analysis of Key Comparisons

Ongoing
DESCRIPTION: With the recent signing of the Mutual Recognition Arrangement (MRA), National Metrology Institutes (NMI's) and Regional Metrology Organizations (RMO's) around the world have committed themselves to establishing the equivalence of their measurement standards. Currently, however, there is
Design Fire Curves

Design Fires for Structures Project

Completed
By 2016, this project aims to develop (1) measurement science for characterizing and measuring repeatable structurally significant fires for large-scale experiments, and (2) a performance-based design framework linking fire intensity with expected structural performance objectives.

Design Methods for Resilient Community Systems

Completed
Objective - To advance design and assessment methods for buildings and infrastructure to improve their ability to support the social and economic functions they support and community resilience. What is the technical idea? Quantitative approaches to identify and evaluate the performance of the built

Design for Tornadoes

Ongoing
Objective To advance tornado hazard mitigation through improved characterization of tornadoes and their interaction with buildings and structures, providing the technical foundation for improvements to tornado load design guidelines, standards, codes, and code adoptions. This includes research and

Designing Advanced Scanning Probe Microscopy Instruments

Ongoing
SPM is a general acronym for various probe instruments. The "P" in SPM stands for various types of probe measurements, such as capacitance (C), force (F), tunneling (T), etc. The scanning tunneling microscope (STM), including custom designs at the CNST, uses the quantum mechanical principle of
joint quantum institute

Designing the Nanoworld: Nanostructure, Nanodevices, and Nano-optics

Ongoing
Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the

Detecting Change Points in Surface Temperature Records

Ongoing
DESCRIPTION: For the purpose of exposition, consider the record daily minimums averaged by month for a station near Reno Nevada. There is a clear drop in the level between 1920 and 1940 and a positive drift starting at about 1980. There is also however, considerable variability due to seasonal

Detector metrology

Ongoing
Improved detector technology in the past two decades has opened a new era in detector metrology of optical radiation measurements. Lower calibration and measurement uncertainties can be achieved with modern detector/radiometer standards than traditionally used source standards (blackbodies and lamps
PCB

Detector Readout Project

Ongoing
NIST’s Quantum Sensors Division develops highly sensitive cryogenic sensors, for example transition-edge sensors (TESs) and kinetic inductance detectors (KIDs), to enable precision measurements in a large range of scientific applications. The successful implementation of these novel sensor

Detector-based color scale

Ongoing
The expanded uncertainty of the NIST primary color-temperature lamp-standards is 8 K ( k=2). However, both the long-term stability and the spectral distribution of the lamps can significantly change with burning time. By performing the tristimulus colorimeter calibrations against detector standards

Determinations of Boron Deposit Quality by Neutron Depth Profiling

Ongoing
Neutrons are not easily detected with high resolution and good efficiency. Consequently, high-quality neutron detectors remain a challenge to manufacture. A few nuclides such as He-3, Boron-10, and Li-6 are commonly used to convert impinging neutrons into an electrical pulse that post-processing

Developing a Materials Innovation Infrastructure

Completed
Phase Field Community Hub ( PFHub) and Benchmarks The Phase Field Community Hub provides a framework that supports phase field practitioners and code developers participating in an effort to improve quality assurance for phase field codes. The main thrust of this effort is the generation of a set of

Development of Biomarker-based Systems for Cancer Detection and Therapy

Completed
Intended impact Although significant progress has been made in both the understanding and treatment of cancer during the last thirty years, it remains the second leading cause of death in the US. The cancer community has set a goal to eliminate cancer-related suffering and death by 2015. To achieve

Development of differential absorption LIDAR Technologies

Ongoing
The basic processes involved in elastic backscatter LIDAR are as follows. A laser emits a pulse of light (typically a few nanoseconds), and as the pulse propagates, the photons interact with molecules and aerosol particles. Some of these, the interactions with aerosols, such as Mie and Rayleigh
