A Deep Reinforcement Learning Approach for Automated Chamber Configuration Replicating mmWave Directional Industrial Channel Behavior

January 25, 2023
Author(s)
Mohamed Hany, Sudantha Perera, Carnot Nogueira, Rick Candell, Kate Remley, Matt Simons
Industrial wireless channels have different characteristics than home and office channels due to their reflective nature. Moreover, the millimeter-wave (mmWave) wireless bands can play a big role in improving industrial wireless systems due to their large

Administering Accessible Vote by Mail Systems

January 25, 2023
Author(s)
Lynn Baumeister, Whitney Quesenbery, Sharon J. Laskowski
Accessible vote by mail (AVBM) provides options for voters with disabilities to complete their absentee or vote by mail ballots independently and privately. AVBM is especially important for voters with print disabilities that make it difficult to read or

Category Theory

January 25, 2023
Author(s)
Spencer Breiner, Eswaran Subrahmanian, Ram Sriram
Category theory (CT) is a branch of mathematics concerned with the representation and composition of structured relationships. Recent interest in systems engineering (SE) stems from the possibility that CT might provide a principled mathematical foundation

Handbook for VVSG 2.0 Usability and Accessibility Test Strategies

January 25, 2023
Author(s)
Whitney Quesenbery, Sharon J. Laskowski
This document provides guidance and resources for how to test voting systems against the usability and accessibility requirements in the Voluntary Voting System Guidelines (VVSG) 2.0. The requirements include Principles 2.2 and 5 through 8. The goal of

Validating commonly-used indicators for community resilience measurement

January 25, 2023
Author(s)
Donghwan Gu, Maria Dillard, Michael Gerst, Jarrod Loerzel
This paper quantitatively examines indicators frequently used to measure community resilience. Based on existing frameworks and methodologies rooted in multiple disciplines, a set of 18 indicators were identified as being most prevalent. A data-driven

Ballot Definition Common Data Format Specification

January 24, 2023
Author(s)
Benjamin Long, John Dziurlaj
This publication describes a ballot definition common data format for the interchange of logical and physical ballot style information. It contains a UML (Unified Modeling Language) model of the election data and a JSON (JavaScript Object Notation) and XML

NIST-F3, a cesium fountain frequency reference

January 24, 2023
Author(s)
Gregory Hoth, Alexander Radnaev, Peter Mitchell, Jeffrey Sherman, Vladislav Gerginov
A cesium fountain frequency reference known as NIST-F3 is under development at the National Institute of Standards and Technology (NIST). The fountain is intended to provide input for the NIST timescale and assist with evaluation of NIST's primary and

ProteomicsML: An Online Platform for Community-Curated Datasets and Tutorials for Machine Learning in Proteomics

January 24, 2023
Author(s)
Tobias Rehfeldt, Ralf Gabriels, Robbin Bouwmeester, Siegfried Gessulat, Magnus Palmblad, Ben Neely, Yasset Perez-Riverol, Tobias Schmidt, Juan Antonio Vizcaino, Eric Deutsch
Dataset acquisition and curation are often the hardest and most time-consuming parts of a machine learning endeavor. This is especially true for proteomics-based LC-IM-MS datasets, due to the high-throughput data structure with high levels of noise and

Wideband Synthetic-Aperture Millimeter-Wave Spatial-Channel Reference System With Traceable Uncertainty Framework

January 24, 2023
Author(s)
Kate Remley, Peter Vouras, Ben Jamroz, Alec Weiss, Jeanne Quimby, Dylan Williams, Rod Leonhardt, Damla Guven, Rob Jones, Joshua Kast
This paper describes a wideband synthetic-aperture system and the associated Fourier processing for generating high-resolution spatial and temporal estimates of the signal propagation environment in wireless communication channels at millimeter-wave

High-Resolution DNA Binding Kinetics Measurements with Double Gate FD-SOI Transistors

January 23, 2023
Author(s)
Seulki Cho, Alexander Zaslavsky, Curt A. Richter, Jacob Majikes, James Alexander Liddle, Francois Andrieu, Sylvain Barraud, Arvind Balijepalli
Double gate fully depleted SOI transistors operating in a remote gate configuration and under closed-loop feedback allow noise performance that exceeds their single gate counterparts by more than an order of magnitude. We leverage this high performance to

Measurement of Transient Environmental Effects in GPS-Disciplined Clocks

January 23, 2023
Author(s)
Andrew Novick, Michael A. Lombardi, Demetrios Matsakis, John Clark
GPS-disciplined clocks (GPSDCs) are designed to optimize the accuracy and stability of their pulse-per-second (PPS) and frequency outputs by steering an internal oscillator to the timing solution from a GPS receiver based on the received satellite signals

Measuring the Timing Accuracy of Satellite Time and Location (STL) Receivers

January 23, 2023
Author(s)
Peter Johnson, Andrew Novick, Michael A. Lombardi
We present measurements of the timing accuracy and stability of Satellite Time and Location (STL) receivers with respect to UTC(NIST), the coordinated universal time scale (UTC) operated by the National Institute of Standards and Technology (NIST). STL is

Micro Common Data Format Specification

January 23, 2023
Author(s)
Benjamin Long, John Dziurlaj
This specification describes a data format for space-constrained environments, such as the placement of machine readable data on paper. The specification is responsive to a need for interoperability in several key voting system scenarios in which the use

Time Transfer using High-Definition Television (HDTV) Broadcast Transmitters in Common View

January 23, 2023
Author(s)
Konstantin Tarasov, Bethany Bauer, Sebastian Olsen, Eugene Graver, Howard Feil, Jeffrey Sherman, Aidan Montare, Matthew J. Deutch, Glenn Nelson, Michael A. Lombardi, Timothy Marczewski, David A. Howe
We have developed and demonstrated a time transfer system using high-definition television (HDTV) broadcast signals in common view. The system is comprised of a software defined radio (SDR), a TV antenna, a digitally programmed crystal oscillator (DOCXO)

Self-driving Multimodal Studies at User Facilities
