Optimal Bayesian Experimental Design

September 4, 2019
Author(s)
Robert D. McMichael
This manual describes an implementation of optimal Bayesian experimental design methods. These methods address routine measurements where data are fit to experimental models in order to obtain model parameters. The twin benefits of these methods are

Comparison of Multiple Methods for Obtaining PO Resistances with Low Uncertainties

September 3, 2019
Author(s)
Kwang Min Yu, Dean G. Jarrett, Albert Rigosi, Shamith Payagala, Marlin E. Kraft
Capabilities for high resistance determinations are essential for calibration of currents below 1 pA, as typically requested in several applications, including semiconductor device characterization, single electron transport, and ion beam technologies

Dietary Supplement Laboratory Quality Assurance Program: Exercise O Final Report

September 3, 2019
Author(s)
Charles A. Barber, Melissa M. Phillips, Catherine A. Rimmer, Laura J. Wood, Maria R. Ale, Stephen E. Long, Elizabeth Mudge, Shannon L. Whitehead
The NIST Dietary Supplement Laboratory Quality Assurance Program (DSQAP) was established in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS) in 2007 to enable members of the dietary supplement community to

Johnson Noise Thermometry

September 3, 2019
Author(s)
Weston L. Tew, Jifeng Qu, K L. Zhou, Samuel P. Benz, Horst Rogalla, David R. White
Johnson noise thermometers infer thermodynamic temperature from measurements of the thermally-induced current fluctuations that occur in all electrical conductors. This paper reviews the status of Johnson noise thermometry and its prospects for both

Measurement of the 10B(?,n0)13N cross section at E? ? 3.6 MeV and its application as a diagnostic at the National Ignition Facilit

September 3, 2019
Author(s)
Q Liu, M Febbraro, R.J. deBoer, A Boeltzig, Y Chen, C Cerjan, M Couder, B Frentz, G Gilardy, J. Gorres, E. A. Henry, E. Lamere, K. T. Macon, K. Manukyan, L. Morales, P. D. O'Malley, S Pain, W. A. Peters, D. Schneider, C. Seymour, R. Toomey, B. Vande Kolk, Jamie Weaver, M. Wiescher
The National Ignition Facility provides the opportunity to study nuclear reactions under controlled conditions at high temperatures and pressures at a level never before achieved. However, the time scale of the DT implosion is only a few nanoseconds

Applications with a Rydberg Atom-based Radio Frequency Antenna/Receiver

September 2, 2019
Author(s)
Matthew T. Simons, Abdulaziz H. Haddab, Joshua A. Gordon, Christopher L. Holloway
We discuss several recent extensions of quantum radio frequency (RF) electric field sensors to antenna/receiver applications. These Rydberg atom-based sensors have been previously studied for SI-traceable RF field measurements. We demonstrate the reception

Design-for-Cost An Approach for Distributed Manufacturing Cost Estimation

September 2, 2019
Author(s)
Minchul Lee, Boonserm Kulvatunyou
Researches have shown that design changes cost more in later stages of product development. Therefore, companies adopt Design-for-X methods to optimize product designs from many aspects in the early design stage. Despite such efforts, they often encounter

Detecting and Receiving Phase-Modulated Signals With a Rydberg Atom-Based Receiver

September 2, 2019
Author(s)
Christopher L. Holloway, Matthew T. Simons, Joshua A. Gordon, David R. Novotny
Recently, we introduced a Rydberg-atom based mixer capable of detecting and measuring of the phase of a radio-frequency field through the electromagnetically induced transparency (EIT) and Autler-Townes (AT) effect. The ability to measure phase with this

The Interfacial Zone Around Nanoparticles in Polymer Nanocomposites

September 2, 2019
Author(s)
Jack F. Douglas, Beatriz Betancourt, Fernando Vargas-Lara, Francis W. Starr, Wengang Zhang
We perform coarse-grained simulations of model nanoparticles having a diameter on the order of 10 nm in an unentangled polymer matrix in the limit of low nanoparticle concentration to understand how the presence of nanoparticles alter the segmental
