Characterization of Long-Term Sub-Hourly Thermal Comfort Performance Data

November 1, 2020
Author(s)
Hyojin Kim, Lisa Ng, Brian P. Dougherty, William V. Payne
Current thermal comfort standards do not provide guidelines on how to graphically characterize and benchmark long-term, sub-hourly, thermal comfort. In an effort to address this void, several statistical characterizations and advanced visualization methods

Materials Research & Measurement Needs for Ceramics Additive Manufacturing

November 1, 2020
Author(s)
Andrew J. Allen, Igor Levin, Suzanne E. Witt
We report on a recent workshop dedicated to additive manufacturing (AM) of ceramics that was held at the National Institute of Standards and Technology (NIST) in November 2019. This two- day all-invited meeting brought together experts from industry

A micromirror array with annular partitioning for high-speed random-access axial focusing

October 29, 2020
Author(s)
Nathan T. Ersumo, Cem Yalcin, Nick Antipa, Nicolas Pegard, Laura Waller, Omar D. Lopez, Rikky Muller
Dynamic axial focusing functionality has recently seen widespread incorporation in microscopy, augmented/virtual reality (AR/VR), adaptive optics, and material processing. Yet the limitations of existing varifocal tools continue to beset the performance

AMB2018-03: Benchmark Physical Property Measurements for Material Extrusion Additive Manufacturing of Polycarbonate

October 29, 2020
Author(s)
Daniel P. Cole, Frank Gardea, Todd C. Henry, Jonathan Seppala, Edward Garboczi, Kalman D. Migler, Christopher M. Shumeyko, Jeffery R. Westrich, Sara Orski, Jeffery L. Gair
Material extrusion (MatEx) is finding increasing applications in additive manufacturing of thermoplastics due to the ease of use and the ability to process disparate polymers. Since part strength is anisotropic and frequently deviates negatively with

Control Baselines for Information Systems and Organizations

October 29, 2020
Author(s)
Ronald S. Ross, Victoria Y. Pillitteri
This publication provides security and privacy control baselines for the Federal Government. There are three security control baselines (one for each system impact level: low-impact, moderate-impact, and high-impact), as well as a privacy baseline that is

Intercritical annealing to achieve a positive strain rate sensitivity of mechanical properties and suppression of plastic instabilities in multi-phase medium-Mn steels

October 29, 2020
Author(s)
Jake Benzing, William E. Luecke, Steven Mates, Dirk Ponge, Dierk Raabe, James Wittig
The present work investigates the room temperature tensile properties of a cold-rolled Fe-12Mn- 3Al-0.05C (% by mass) steel designed to have a multi-phase microstructure and positive strain rate sensitivities. An increase in intercritical annealing time

PSCR 2020_ Connecting the First Responder's Environment

October 29, 2020
Author(s)
Donald L. Harriss
In most first responder events, a building or structure is involved with some degree of importance. Knowledge of building structures and current building environments is paramount to successfully fulfilling an emergency event. To investigate this fact

PSCR 2020_ LMR Data Collection for Traffic Modeling

October 29, 2020
Author(s)
Christopher D. Dennis, Yishen Sun
The Land Mobile Radio (LMR) Data Collection Project creates a database of Public Safety (PS) LMR usage for traffic/call modeling. The generated models are used by telecom providers and PS entities for future technology deployments (e.g., LTE and 5G). This

PSCR 2020_ Tech to Protect - Year in Review

October 29, 2020
Author(s)
Craig T. Connelly, Jason D. Kahn, Gary S. Howarth, Margaret Pinson, Bill Schrier, Charles Hardnett, Lauren Schluzas, Austin Handle, Levi Adissi, Francis Lin, Zack Braun
Launched in April 2019, the Tech to Protect Challenge is one year old. This session will recap the progress to date, highlight recent national award winners, and share the next steps for participants moving forward. This session features two panels: first

PSCR 2020_5G Security – Evolution not Revolution

October 29, 2020
Author(s)
Jeffrey A. Cichonski
5G has promised to change the way we communicate with an ambitious slate of capabilities not yet available in the 5G networks deployed today, but rather are still being developed and specified by 3GPP. To understand the security posture of 5G networks

PSCR 2020_Access Driven Modified Rhyme Test Intelligibility

October 29, 2020
Author(s)
Jaden K. Pieper, Stephen D. Voran
Previous work by NIST/PSCR focused on developing a quality of experience-based access time measurement system. This system relies on modified rhyme test (MRT) word intelligibility and focuses on intelligibility when incrementally cutting off portions of

PSCR 2020_Building VR for Public Safety

October 29, 2020
Author(s)
Jack R. Lewis, Christopher E. Johnson, Jeffrey L. Karhoff
In this presentation members of the UI/UX Virtual Reality development team from PSCR NIST will show their process for designing and building VR simulations for public safety.

PSCR 2020_CHARIoT Prize Challenge Discussion

October 29, 2020
Author(s)
Scott A. Ledgerwood, Donald L. Harriss, Paul D. Merritt, Bill Gillman, Scott Turnbull
The CHARIOT Challenge launched in early 2020 with a focus on bringing the internet of things (IOT) sensors from personal area networks, smart buildings, and smart cities to the hands of public safety using augmented reality. Contestants worked on parallel
