Impact of LTE Signals on GPS Receivers

Completed
To better understand the potential impact of adjacent-band LTE signals on GPS receiver performance, NASCTN developed a draft test plan designed to measure how the performance of GPS receivers changed as a function of increasing LTE signal power relative to a baseline with no LTE emissions. NASCTN

Impact of Material Composition on Ignitability and Fire Growth

Ongoing
Volume 1 Experimental Observations of the Burning Behavior of Combustible Solids in Parallel Panel Configuration at Full-Scale ( NIST Technical Note 2282 ) Report Summary This report provides an overview of measurements (e.g., heat release rate, gaseous species production, and flame-to-surface heat

Impact Metrics

Ongoing
In response to h-index requests from NIST management and staff, Library staff provide comprehensive publication analysis studies and reports that ensure the h-index is put in proper context as one of several ways to assess the impact of an individual or group. The Library can also compile non

Improved Assessment Criteria for Performance-Based Seismic Design

Completed
Objective - Task (1): To establish a new generation of performance-based design assessment criteria that captures a component action’s dependence on loading history by conducting a set of focused experimental tests and computer simulations on eccentrically braced frame link beams. Task (2): To vet

Improved Benchtop Connectivity to Complex Microfluidic Devices

Completed
Intended impact Microfluidic devices with many fluidic and pneumatic inlets are difficult to connect to benchtop reservoirs and controllers. Many hours can be spent sorting, untangling, and connecting tubing to a single device. If one then finds that the device is not fully functional, the process

IMS Visualization

Ongoing
To provide visualization tools for use by the IMS project and other network researchers to support development of fundamental metrics. NIST has a high level of visualization expertise and the vast amount of data being produced by the Fundamental Measures (IMS) project requires these types of

Index Properties of Optical Materials (0.12 μm – 15 μm)

Ongoing
The real part of the refractive index, its wavelength dispersion, and its temperature dependence are the key parameters for the design of refractive optical elements for optical systems. The demands for continually improved precision of optical instruments has driven a need for increasingly accurate

The Indianapolis (INFLUX) Urban Test Bed

Ongoing
Observation Network Various types of atmospheric GHG observations have been deployed as part of the INFLUX project: Tower-based in-situ, continuous measurements of CO 2, CH 4, and CO Flask sampling of 14CO 2 and other trace gases (currently at two towers) Periodic aircraft sampling of greenhouse

Industrial Artificial Intelligence Management and Metrology (IAIMM)

Ongoing
IAIMM has identified IAI systems for decision making, planning, and control in manufacturing as a prime candidate for better Standard Operating Procedures (SOPs) centered on both use and evaluation. The specific use case of multi-stage manufacturing presents a broad scope of application to

Industrial: Enhanced X-Ray Imaging

Ongoing
A variety of in-house x-ray sources and detector technologies invite efforts to optimize traditional image quality metrics and the use of algorithms and methods to extract the maximum amount of information available. These results are used to inform x-ray standards development and will drive the

Industrial Wireless Testbed for Time-Sensitive Networking (TSN)

Ongoing
The Industrial Wireless Testbed for Time-Sensitive Networking (TSN), a collaborative endeavor with Intel Laboratories, is positioned to be a groundbreaking exploration with a multi-faceted set of objectives. The project goal is to investigate and enhance the application of TSN in Wi-Fi networks

H5 Influenza Positive Controls

Ongoing
In response to the current H5N1 avian influenza outbreak, NIST has developed a research grade test material (RGTM) for PCR-based assays. This material contains 3 vials with RNA fragments for HA (Part A), NA (Part B), and MP (Part C). A NIST Reference Material is also under development. The guidance

Information Centric Networking Program

Ongoing
Today the Internet relies on content distribution network overlays and caching to deliver most of its traffic. It is not clear that this architecture can continue to scale to meet data projections of the next decade and beyond. Current research in information-centric networking proposes a new

Infrared cryogenic blackbody broadband calibration

Ongoing
The broadband chamber and the spectral calibration chamber at the LBIR facility are used for calibrating the customer cryogenic blackbodies. These chambers are cooled by closed cycle helium gas at 20 K to provide a background equivalent to space. The absolute cryogenic radiometers (ACRs) in these

Infrared optical properties of materials and components

Ongoing
Our overall program can be summarized by the following 6 key elements: Provide a traceability path to national scales for infrared optical properties to the infrared optical properties community through, NIST Calibration Service 38075S, Standard Reference Materials, cooperative research and

Infrastructure for Agile Manufacturing Data Standards

Completed
Objective - T o develop and deploy to industry advances in standards and measurement science for model-based messaging standards and service-modeling methodology to enable manufacturers to improve the agility of manufacturing systems and manufacturing systems integration. What is the technical idea

Inkjet Printing and Precision Deposition

Ongoing
Inkjet Droplet Metrology: Drop-on-Demand (DOD) inkjet printing allows precise deposition of picoliter (pL)-size droplets of solutions containing organic or inorganic materials. These drops can be used to create unique patterns, structures, and coatings and build 3-D microstructures making it a

Inorganic Phase Equilibrium Data

Ongoing
Every deliberate effort to develop a new material or to improve processing begins with chemical composition and the conditions (temperature, pressure) under which pure compounds and their mixtures are stable ( an equilibrium phase diagram ). In the absence of such information, materials scientists
