Strain-life performance in hydrogen of DOT pressure vessel steel

November 7, 2022
Author(s)
May Ling Martin, Peter Bradley, Damian Lauria, Robert L. Amaro, Matthew Connolly, Andrew Slifka
Strain-life testing of a 4130 pressure vessel steel was conducted in air and in a high-pressure gaseous-hydrogen environment. Hydrogen causes an order of magnitude decrease in lifetime compared to in-air performance at the same strain-amplitudes. This

When Frodo Flips: End-to-End Key Recovery on FrodoKEM via Rowhammer

November 7, 2022
Author(s)
Michael Fahr Jr., Hunter Kippen, Andrew Kwong, Thinh Dang, Jacob Lichtinger, Dana Dachman-Soled, Daniel Genkin, Alexander Nelson, Ray Perlner, Arkady Yerukhimovich, Daniel Apon
In this work, we recover the private key material of the FrodoKEM key exchange mechanism as submitted to the NIST PQC standardization process. The new mechanism that allows for this is a Rowhammer-assisted poisoning of the FrodoKEM KeyGen process. That is

Compensation of Electrical Current Drift in Human-Robot Collision

November 5, 2022
Author(s)
Vinh Nguyen, Jennifer Case
Human-robot collaborative systems are being increasingly adopted in manufacturing environments due to their application flexibility, adaptability, and cost-effectiveness. These systems typically use electrical current sensors to measure joint torque in

ORGANIZATION OF SCIENTIFIC AREA COMMITTEES (OSAC) FOR FORENSIC SCIENCE

November 4, 2022
Author(s)
John Jones, Allison Getz, Donna J. Sirk
The National Institute of Standards and Technology (NIST) established the Organization of Scientific Area Committees (OSAC) for Forensic Science in 2014 to address a lack of discipline-specific forensic science standards. OSAC's mission is to strengthen

Evaluating Inter-Laboratory Comparison Data

November 3, 2022
Author(s)
Enrico Frahm, John D. Wright
The primary purpose of inter-laboratory comparisons is to demonstrate that the uncertainty specifications of the calibration measurement capabilities of the participating laboratories are correct. The most common criterion for assessing a participating

GRID-VIDEO MEASUREMENT METHOD FOR A-UGV'S SMALL OBSTACLE AVOIDANCE PERFORMANCE

November 3, 2022
Author(s)
Soocheol Yoon, Roger V. Bostelman, Ann Virts
With the advancement of factory logistics into the autonomous era comes the need to validate the safety and performance characteristics of Autonomous-Unmanned Ground Vehicles (A-UGVs) working in these application spaces ASTM Committee F45 has been

Quadrature Squeezing And Temperature Estimation From The Fock Distribution

November 3, 2022
Author(s)
Italo Pereira Bezerra, Hilma Vasconcelos, Scott Glancy
We present a method to estimate the amount of squeezing and temperature of a single-mode Gaussian harmonic oscillator state based on the weighted least squares estimator applied to measured Fock state populations. Squeezing and temperature, or equivalently

Aluminum Formate, Al(HCOO)3: An Earth-Abundant, Scalable, and Highly Selective Material for CO2 Capture

November 2, 2022
Author(s)
Hayden Evans, Dinesh Mullangi, Zeyu Deng, Yuxiang Wang, Shing B. Peh, Fengxia Wei, John Wang, Craig Brown, Dan Zhao, Pieremanuele Canepa, Anthony K. Cheetham
A combination of gas adsorption and gas breakthrough measurements show that the metal-organic framework, Al(HCOO) 3 (ALF), which can be made inexpensively from commodity chemicals, exhibits excellent CO 2 adsorption capacities and outstanding CO 2/N 2

Cryptographic Standards in a Post-Quantum Era

November 2, 2022
Author(s)
Dustin Moody, Angela Robinson
If large-scale quantum computers are ever built, they will compromise the security of many commonly used cryptographic algorithms. In response, the National Institute of Standards and Technology is in the process of standardizing new cryptographic
