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

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
