Absolute radiation pressure detector using a diamagnetically levitating test mass

October 28, 2021
Author(s)
Anna Vaskuri, Daniel Rahn, Paul A. Williams, John H. Lehman
We have developed an absolute radiometer to measure laser power by means of radiation pressure in a closed control-loop configuration using diamagnetically levitated pyrolytic graphite as the soft spring and gravity as a contactless restoring force. Our

A Reference Correlation for the Viscosity of Krypton From Entropy Scaling

October 27, 2021
Author(s)
Sofia Polychroniadou, Konstantinos Antoniadis, Marc Assael, Ian Bell
We present a new wide-ranging correlation for the viscosity of krypton based on critically evaluated experimental data. For the first time, such a correlation has as its basis the entropy scaling approach. We base the residual contribution on the Lennard

Analysis of complex multidimensional optical spectra by linear prediction

October 27, 2021
Author(s)
Ethan Swagel, Jagannath Paul, Alan Bristow, Jared Wahlstrand
We apply Linear Prediction from Singular Value Decomposition (LPSVD) to the analysis of two-dimensional complex optical spectra. LPSVD is a non-iterative procedure that fits time-domain complex data to the sum of damped sinusoids, or Lorentzian peaks in

Separation of Peas and Carrots in Boiling Water

October 27, 2021
Author(s)
Zachary H. Levine
Frozen peas and carrots are commonly available in grocery stores in the United States. The carrots are cut into cubes roughly 8 mm on a side. They are prepared together in water which is brought to a boil. Sometimes peas and carrots which are initially

Non-volatile Multi-level Switching in Artificial Synaptic Transistors Based on Epitaxial LiCoO2 Thin Films

October 26, 2021
Author(s)
Heshan Yu, Megan E. Holtz, Yunhui Gong, Justin Pearson, Yaoyu Ren, Andrew Herzing, Xiaohang Zhang, Ichiro Takeuchi
Li-ion synaptic transistors offer non-volatile multi-level switching through Li-ion exchange between channel and electrolyte, and thus are widely regarded as promising candidates for the neuromorphic computing. However, a relatively low switching speed in

Configuration and Control of a Millimeter-Wave Synthetic Aperture Measurement System with Uncertainties

October 25, 2021
Author(s)
Alec J. Weiss, Jeanne Quimby, Rodney Leonhardt, Benjamin Jamroz, Dylan Williams, Kate Remley, Peter Vouras, Atef Elsherbeni
This paper discusses the configuration and control of a new millimeter wave over-the-air measurement system. This system provides unparalleled measurement accuracy, flexibility, and the ability to bound uncertainties on its measurements. The system also

NIST Security Awareness Study

October 25, 2021
Author(s)
Jody Jacobs, Julie Haney, Susanne M. Furman
This is a presentation for the September 28, 2021 FISSEA conference. This presentation is on the NIST Security Awareness Study. The goal of the study is to better understand the needs, challenges, practices, and professional competencies of federal

Verification of the Channel Estimator Evaluator

October 25, 2021
Author(s)
Jeanne Quimby, Alec Weiss, Atef Elsherbeni
Fifth-generation millimeter-wave communications rely on channel estimators to correctly predict the frequency response of the propagating channel. Millimeter-wave communication systems have non-ideal hardware performance, such as phase noise, which
