Operational Impacts of IEEE 802.1Qbv Scheduling on a Collaborative Robotic Scenario

October 17, 2022
Author(s)
Rick Candell, Karl Montgomery, Mohamed Hany, Susruth Sudhakaran, Justin Albrecht, Dave Cavalcanti
Time-sensitive networking (TSN) is an emerging topic for the advancement of wireless networking for industrial applications. TSN, as defined under the umbrella of IEEE 802.1 standards, addresses issues related to providing deterministic communications over

Feasibility of using depth cameras for evaluating human - exoskeleton interaction

October 14, 2022
Author(s)
Soocheol Yoon, Ya-Shian Li-Baboud, Ann Virts, Roger V. Bostelman, Milli Shah
With increased use of exoskeletons in a variety of fields such as industry, military, and health care, there is a need for measurement standards to understand the effects of exoskeletons on human motion. Optical tracking systems are the current gold

Potential artifacts and control experiments in toxicity tests of nanoplastic and microplastic particles

October 14, 2022
Author(s)
Elijah Petersen, Ana Barrios, Theodore Henry, Monique Johnson, Albert Koelmans, Antonio Montoro Bustos, Joanna Matheson, Matthias Roesslein, Jian Zhao, Baoshan Xing
To fully understand the potential ecological and human health risks from nanoplastics and microplastics (NMPs) in the environment, it is critical to make accurate measurements. Similar to past research on the toxicology of engineered nanomaterials, a broad

Radio Spectrum Occupancy Measurements Amid COVID-19 Telework and Telehealth

October 14, 2022
Author(s)
Dan Kuester, Xifeng Lu, Dazhen Gu, Azizollah Kord, Jake Rezac, Katie Carson, Marla L. Dowell, Elizabeth Eyeson, Ari Feldman, Keith Forsyth, Vu Le, John Marts, Mike McNulty, Kyle Neubarth, Andre Rosete, Matthew Ryan, Maija Teraslina
During the COVID-19 pandemic, NIST began a targeted campaign of measurements of averaged power and occupancy rate in the radio spectrum. The purpose was to sample real environments to offer timely insights into data infrastructure where it might be

Snappy: A New Automated Testing Machine for Monitoring the Break Evolution Process during Single Fiber Fragmentation Test

October 14, 2022
Author(s)
Ami Ahure Powell, Richard Sheridan, Berkay Yucel, Sezen Yucel, Evan Rust, Jeremiah Woodcock, Jeffrey Gilman, Surya R. Kalidindi, Gale A. Holmes
A measurement of interfacial shear strength (IFSS) in fiber reinforced polymer (FRP) materials remains elusive after more than fifty years. This is due in part to the many sources of uncertainty, the time-consuming nature of the measurements, and the large

Linking viscosity to equation of state using residual entropy scaling theory

October 13, 2022
Author(s)
Xiaoxian Yang, Xiong Xiao, Monika Thol, Markus Richter, Ian Bell
In our previous work, a residual entropy scaling (RES) approach was developed to link viscosity to residual entropy (a thermodynamic property calculated with an equation of state, EoS) using a simple polynomial equation for refrigerants. This work extends

Extracting Mathematical Concepts from Text

October 12, 2022
Author(s)
Jacob Collard, Valeria de Paiva, Brendan Fong, Eswaran Subrahmanian
We investigate some different systems for extracting mathematical entities from texts in the mathematical field of category theory, as a first step for constructing a mathematical knowledge graph. We consider four different term extractors and compare

Improving Support-Minors rank attacks: applications to GeMSS and Rainbow

October 12, 2022
Author(s)
John Bayron Baena Giraldo, Pierre Briaud, Daniel Cabarcas Jaramillo, Ray Perlner, Daniel Smith-Tone, Javier Verbel
The Support-Minors (SM) method has opened new routes to attack multivariate schemes with rank properties that were previously impossible to exploit, as shown by the recent attacks of [9, 40] on the Round 3 NIST candidates GeMSS and Rainbow respectively. In

On the "intrinsic" breakdown of thick gate oxide

October 12, 2022
Author(s)
Kin (Charles) Cheung
Thick gate oxide breakdown mechanism becomes an important topic again due to the rising demand of power electronics. The failure of the percolation model in explaining the observed Weibull shape factor of thick oxide breakdown distribution seriously

This report provides supplemental information to NISTIR 8352 Bitemark Analysis: A NIST Scientific Foundation Review. Publicly available resources relating to bitemark analysis were collected to assist in the review of the scientific foundations of bitemark

CSAFE Bitemark Thinkshop Report

October 11, 2022
Author(s)
NFN CSAFE, Kelly Sauerwein
This is supplemental information to NISTIR 8352 Bitemark Analysis: A NIST Scientific Foundation Review. NIST asked the Center for Statistics and Applications in Forensic Evidence (CSAFE), a NIST Forensic Science Center of Excellence, to organize a Bitemark

This report provides supplemental information to NISTIR 8352 Bitemark Analysis: A NIST Scientific Foundation Review. Standards and guidelines from the American Dental Association (ADA) and the International Organization of Standardization (ISO) as well as

Unravelled and Glassy Magnetism in PbFe 1/2 Nb 1/2 O 3 - (2) Neutron Scattering

October 11, 2022

C. Stock, B. Roessli, Peter M. Gehring, Jose Rodriguez Rivera, N. Giles-Donovan, S. Cochran, Guangyong Xu, P. Manuel, M. J. Gutmann, William D. Ratcliff, T. Fennell, Y. Su, X. Li, H. Luo
We apply neutron scattering to investigate the magnetism in the relaxor ferroelectric PbFe 1/2Nb 1/2O 3 (PFN). Similar to the lack of spatially long-range ferroelectric order in prototypical relaxors like Pb(Mg,Zn) 1/3Nb 2/3O 3 (PMN and PZN), spatially

Bi 12 O 17 Cl 2 with a Sextuple Bi-O Layer Composed of Rock-Salt and Fluorite Units and its Structural Conversion through Fluorination to Enhance Photocatalytic Activity

Kirsanova, Richard Dronskowski, Hajime Suzuki, Chengchao Zhong, Cedric Tassel, Kohdai Ishida, Yosuke Matsuzaki, Craig Brown, Koji Fujita, Kotaro Fujii, Masatomo Yashima, Yoji Kobayashi, Akinori Saeki, Itaru Oikawa, Hitoshi Takamura, Ryu Abe, Hiroshi Kageyama, Tatiana E. Gorelik, Artem M. Abakumov
Layered bismuth oxyhalides with bilayered (Bi 2O 2) fluorite slabs are promising visible-light photocatalysts because of the ability to control the valence band levels. Here we show that a structurally uncharacterized Bi 12O 17Cl 2, which has been
