Separable Shape Tensors for Aerodynamic Design

January 31, 2023
Author(s)
Zachary J. Grey, Andrew Glaws, Olga Doronina
Airfoil shape design is a classical problem in engineering and manufacturing. In this work, we combine principled physics-based considerations for the shape design problem with modern computational techniques using a data-driven approach. Modern and

Design Guide for New Tornado Load Requirements in ASCE 7-22

January 30, 2023
Author(s)
Erik Perfetto, James Taylor, Karah Osburn, Brian O'Connor, Marc Levitan, Jennifer Mitchell
This instructional guidance is for design professionals and building officials to help them determine when a building or other structure is required to be designed to minimum tornado loads and how to calculate design tornado forces. This guide is in

Handout: Users Are Not Stupid: 6 Cybersecurity Pitfalls Overturned

January 30, 2023
Author(s)
Julie Haney, Susanne M. Furman
The cybersecurity community tends to focus and depend on technology to solve today's cybersecurity problems, often without taking into consideration the human element - the key individual and social factors impacting cybersecurity adoption. This handout

Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices

January 30, 2023
Author(s)
Tina G. Butcher, Richard A. Harshman, Jan Konijnenburg, Gloria Diane Lee, Juana Williams, Lisa Warfield, Shelby Bowers, Katrice Lippa, Elizabeth Benham
NIST Handbook 44 includes specifications, tolerances, and other technical requirements for weighing and measuring devices. These requirements are intended to encourage the design, installation, testing, and use of weighing and measuring devices that

Photon echoes using atomic frequency combs in Pr:YSO -- experiment and semiclassical theory

January 30, 2023
Author(s)
Zachary H. Levine, Aditya N. Sharma, Kumel H. Kagalwala, Martin A. Ritter, Eli J. Weissler, Elizabeth A. Goldschmidt, Alan Migdall
Photon echoes in rare-earth-doped crystals are studied to understand the challenges of making broadband quantum memories using the atomic frequency comb (AFC) protocol in systems with hyperfine structure. The hyperfine structure of Pr3+ poses an obstacle

Validation of open-path dual-comb spectroscopy against an O2 background

January 30, 2023
Author(s)
Nathan Malarich, Brian Washburn, Kevin Cossel, Fabrizio Giorgetta, Griffin Mead, Daniel Herman, Nathan R. Newbury, Ian Coddington
Dual-comb spectroscopy measures greenhouse gas concentrations over kilometer-length open-air paths with high precision. However, characterizing the absolute accuracy of these outdoor measurements is challenging, as most gas species have fluctuating

Voices of First Responders: Communication Center & 9-1-1 Services
