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
Workshop floor

Wireless Systems for Industrial Environments

Completed
Objective: The Wireless Systems for Industrial Environments (WSIE) project will deliver comprehensive, measurement science-based guidelines in the selection, deployment, and optimization of the wireless technologies in specific manufacturing environments; and research that advances the state of

Wireless Systems Metrology

Ongoing
The Wireless Systems Metrology Program supports the growing wireless industry by developing methods to test the operation and functionality of wireless devices in the presence of various types of distortion. This includes multipath distortion, ranging from a line-of-sight environment (low-multipath)

XML Technologies

Ongoing
The Extensible Markup Language (XML) and the related XML-based recommendations provides a core infrastructure that will enable this next level of web applications. The success of this technology will be dependent upon the industry's ability to produce applications that are interoperable. Within
example sample for tomography

X-Ray Computed Microtomography

Ongoing
Impact XCT gives information that cannot be obtained any other way from opaque materials and objects. It gives us an “eye inside” so that features, of a certain size range, can be seen. The Division’s XCT instruments can reconstruct 3D images with a voxel size down to about 0.5 micrometers, at the

X-ray computed tomography (CT) for medical applications

Completed
As scale lengths get smaller, diffraction becomes increasingly prominent in tomography. The work here develops diffraction tomography for laboratory sources. A new laboratory scale instrument at NIST/Boulder is dedicated to tomography of integrated circuit interconnects. Tomography software written

X-ray Stress Measurement

Ongoing
X-ray diffraction is commonly used to measure a materials crystal structure, crystal lattice orientation, and the spacing of the lattice planes. Our X-ray systems are designed to measure the spacing of one or two specifically selected lattice plane reflections for a given material. The systems use
Catalyst Testbed

X-ray Testbed for Breakthrough Catalyst Measurements

Ongoing
Interested in collaborating? See below What does this project do for industry? Current measurement techniques are unable to follow the reaction pathways during catalysis and are limited to observing only the end products or looking at catalysts outside of realistic reaction conditions. Our new

Yield Surface Measurement

Ongoing
The overarching philosophy for this project is to develop standard tests that produce clean multiaxial yield data for sheet metal that will be of use to the automotive industry in lightweighting efforts. To this end, it is required that the sheet being tested remain in the as-received condition (no

Zeno

Ongoing
The Zeno software tool computes material, solution, and suspension properties for a specified particle shape or molecular structure using path-integral and Monte Carlo methods. The software was originally developed in Fortran77 at the Stevens Institute of Technology with support from NIST MML. ITL

µMAG: Micromagnetic Modeling Activity Group

Ongoing
µMAG advances the state of the art in micromagnetic modeling by establishing and maintaining communications among interested researchers, by defining a collection of standard micromagnetic problems, and by leading the development of a public reference implementation of micromagnetic software.
