A Novel CMM Interim Testing Artifact

January 1, 1994
Author(s)
Steven D. Phillips, Bruce R. Borchardt, Gregory W. Caskey, David E. Ward, Bryon S. Faust, Daniel S. Sawyer
NIST is currently developing equipment and techniques to rapidly access the performance of Coordinate Measuring machines (CMMs). This will allow the frequent testing of CMMs to insure that they measure parts accurately. A novel interim testing artifact

Real-Time Control Systems for Robots

June 21, 1985
Author(s)
M L. Fitzgerald, Tony Barbera, James S. Albus
The advent of low cost microcomputer hardware has provided the capability for sophisticated control of robot machinery, allowing such features as straight line trajectory motions, sensory interaction, workstation integration, external database access and

Integrating MTConnect and IndoorGML for Asset Monitoring and Indoor Navigation

July 16, 2021
Author(s)
Aaron M. Hanke, Teodor Vernica, William Z. Bernstein
Interoperability across emerging visualization modalities, including augmented reality (AR) and virtual reality (VR), remains a challenge with respect to industrial applications. One critical issue relates to the lack of standard approaches for

Measuring and Improving the Effectiveness of Defense-in-Depth Postures

January 26, 2017
Author(s)
Peter M. Mell, James Shook, Richard Harang
Defense-in-depth is an important security architecture principle that has significant application to industrial control systems (ICS), cloud services, storehouses of sensitive data, and many other areas. We claim that an ideal defense-in-depth posture is

SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions

August 4, 2015
Author(s)
National Institute of Standards and Technology (NIST), Morris J. Dworkin
This Standard specifies the Secure Hash Algorithm-3 (SHA-3) family of functions on binary data. Each of the SHA-3 functions is based on an instance of the KECCAK algorithm that NIST selected as the winner of the SHA-3 Cryptographic Hash Algorithm

Feasibility Study of a Neutron-based Method for Field Measurement of Chloride in Concrete

September 30, 2025
Author(s)
Huaiyu Chen-Mayer, Shannon Hoogerheide, Aiysha Ashfaq, Jacob LaManna, Scott Jones, Mohamad Al-Sheikhly, Richard A. Livingston
Chloride in concrete is known to promote corrosion of the interior metal enforcement which leads to structural degradation. Chloride content monitoring is an important task for maintaining infrastructure integrity. The current industrial practice of

Synthesis and Characterization of the Novel Breathing Pyrochlore Compound Ba3Tm2Zn5O11

December 6, 2024
Author(s)
Lalit Yadav, Rabindranath Bag, Ramesh Dhakal, Stephen Winter, Jeffrey Rau, Alexander Kolesnikov, Andrey Podlesnyak, Craig Brown, Nicholas Butch, David Graf, Michel Gingras, Sara Haravifard
In this study, a novel material from the rare-earth based breathing pyrochlore family, Ba3Tm2Zn5O11, was successfully synthesized. Powder x-ray diffraction and high-resolution powder neutron diffraction confirmed phase purity and the F ¯43m breathing

Visualizing 3D Morphologies and Spatial Heterogeneities of Li after Fast- Charging via In-situ Neutron Tomography

March 22, 2024
Author(s)
Maha Yusuf, Anders Kaestner, Markus Wied, Jacob LaManna, Nghia Vo, Alison Dunlop, Andrew Jansen, Bryant Polzin, Stephen Trask, Markus Strobl, Vanessa Wood, Michael Toney, Johanna Weker
Mechanistic understanding of Li plating is imperative to developing fast-charging batteries for sustainable electric vehicles. Here, we report in-situ 3D characterization of the morphology and spatial heterogeneities of Li plating using neutron micro

Perspective: use and reuse of NMR-based metabolomics data: what works and what remains challenging

March 13, 2024
Author(s)
Tracey Schock, Goncalo Gouveia, Thomas Head, Leo L. Cheng, Chaevian Clendinen, John Cort, Xiuxia Du, Edison Arthur, Candace Fleischer, Jeffrey C. Hoch, Nathaniel Mercaldo, Wimal Pathmasiri, Daniel Raftery, Lloyd Sumner, Panteleimon Takis, Valerie Copie, Hamid R. Eghbalnia, Robert Powers
The National Cancer Institute (NCI) issued a Request for Information (RFI) in October 2022, soliciting input on using and reusing metabolomics data. This RFI aimed to seek input on best practices for metabolomics data storage, management, and use/reuse. In

Tracking Active Phase Behavior on Boron Nitride during the Oxidative Dehydrogenation of Propane Using Operando X-Ray Raman Spectroscopy

November 6, 2023
Author(s)
Melissa Cendejas, Oscar Paredes Mellone, Unni Kurumbail, Zisheng Zhang, Jacob Jansen, Faysal Ibrahim, Son Dong, John Vinson, Anastassia Alexandrova, Dimosthenis Sokaras, Simon Bare, Ive Hermans
Hexagonal boron nitride (hBN) is a highly selective catalyst for the oxidative dehydrogenation of propane (ODHP) to propylene. Using a variety of ex situ characterization techniques, the activity of the catalyst has been attributed to the formation of an

Reusable Network Simulation for CPS Co-Simulations

May 9, 2023
Author(s)
Himanshu Neema, Harmon Nine, Thomas Roth
Cyber-Physical Systems (CPS) require seamless integration of physical and computation components through communication networks. They often contain sub-systems from different physical domains (e.g., electrical, mechanical, and electronic) that must

Towards an Integrated Simulation Platform for Internet of Vehicles
