Configurational Temperature: Verification of Monte Carlo Simulations

October 1, 1998
Author(s)
B D. Butler, G Ayton, O G. Jepps, D J. Evans
A diagnostic that is useful for checking the algorithmic correctness of Monte Carlo computer programs is presented. The check is made by comparing the Boltzmann temperature input to the program and used to accept or reject moves, with the configurational

Visual Measurement Technique for Analysis of Nucleate Flow Boiling (NISTIR 5519)

October 1, 1994
Author(s)
Mark A. Kedzierski, J. M. Crowder, A. M. Jacobi, L. Zhang
This report records a visual measurement technique for analyzing bubbles formed by nucleate flow boiling. The purpose of measuring these bubbles is to expand understanding the boiling process. By studying the behavior of these vapor bubbles, a better

Classification and treatment of errors in reference mass spectra

February 27, 1994
Author(s)
Anzor I. Mikaia, S G. Lias, Stephen E. Stein
Requirements to reference spectra and criteria for mass spectrum inclusion, modification and deletion are developed as a result of evaluation of thousands of spectra and analysis of encountered errors. Errors due to a sample, device and operator, data

Validation Testing Laboratory User

October 1, 1991
Author(s)
Newton Breese, Michael Mclay, G Silvernale
This document is designed to be a quick reference for those people using the Validation Testing Laboratory of the National PDES Testbed located at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. This document is not

A Cell Control Architecture for Flexible Manufacturing

April 1, 1987
Author(s)
Charles R. McLean
The software architecture of the cell control system in the Automated Manufacturing Research Facility (AMRF) at the National Bureau of Standards is presented. The cell control system manages production and support operations for an automated small batch

Nanoscale Hygromechanical Behavior of Lignin

September 22, 2018
Author(s)
Kristen M. Hess, Jason Killgore, Wil Srubar
The nanoscale hygromechanical behavior of lignin is presented in this work. Three atomic force microscopy experimental methods were used to correlate moisture sorption of lignin to its mechanicalbehavior. First, sorption isotherms were established using

Perfect cheating is impossible for single-qubit position verification

June 28, 2024
Author(s)
Carl A. Miller, Yusuf Alnawakhtha
In quantum position verification, a prover certifies her location by performing a quantum computation and returning the results (at the speed of light) to a set of trusted verifiers. One of the very first protocols for quantum position verification was

Collection Methods for High-SNR I/Q Recordings of FDD LTE User Equipment Emissions

May 3, 2024
Author(s)
Keith Forsyth, Aric Sanders, Dan Kuester, Adam Wunderlich
This report documents collection methods for high signal-to-noise ratio (SNR) in-phase and quadrature (I/Q) radio frequency (RF) recordings of long-term evolution (LTE) uplink emissions from a commercial-off-the-shelf (COTS) handset in a fully conducted

A branch-and-bound algorithm with growing datasets for large-scale parameter estimation

February 23, 2024
Author(s)
Susanne Sass, Alexander Mitsos, Dominik Bongartz, Ian Bell, Nikolay Nikolov, Angelos Tsoukalas
The solution of nonconvex parameter estimation problems with deterministic global optimization methods is desirable but challenging, especially if large measurement data sets are considered. We propose to exploit the structure of this class of optimization

Extending Explainable Boosting Machines to Scientific Image Data

November 30, 2023
Author(s)
Daniel Schug, Sai Yerramreddy, Rich Caruana, Craig Greenberg, Justyna Zwolak
As the deployment of computer vision technology becomes increasingly common in science, the need for explanations of the system and its output has become a focus of great concern. Driven by the pressing need for interpretable models in science, we propose

Dynamical Instability of 3d Stationary and Traveling Planar Dark Solitons

November 9, 2022
Author(s)
Ian Spielman, Amilson R. Fritsch, T. Mithun, Panayotis Kevrekidis
Here we revisit the topic of stationary and propagating solitonic excitations in self-repulsive three-dimensional Bose-Einstein condensates by quantitatively comparing theoretical analysis and associated numerical computations with our experimental results

Simulation-guided resonant soft X-ray scattering for determining microstructure of triblock copolymers

August 1, 2022
Author(s)
Eliot Gann, Veronica Reynolds, Michael L. Chabinyc, Christopher Bates, Devon Callan, Elizabeth Murphy, Yan-Qiao Chen, Kaitlin Albanese, Claire Wu, Craig Hawker
Resonant soft X-ray scattering (RSoXS) probes structure with chemical sensitivity that is useful for determining the morphology of multiblock copolymers. However, the hyperspectral data produced by this technique are challenging to interpret. Here, we use

Trapped electrons and ions as particle detectors

August 5, 2021
Author(s)
Jacob Taylor, Daniel Carney, Hartmut Haffner, David Moore
Electrons and ions trapped with electromagnetic fields have long served as important high- precision metrological instruments, and more recently have also been proposed as a platform for quantum information processing. Here we point out that these systems
