CYCLE_D: NIST Vapor Compression Cycle Design Program, Version 6.0; User's Guide

November 19, 2018
Author(s)
Piotr A. Domanski, J S. Brown, Eric W. Lemmon
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or blends of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat

Gain Calibration of Current-to-Voltage Converters

November 19, 2018
Author(s)
Thomas C. Larason, Carl C. Miller
Current-to-voltage converters are used in many photometric and radiometric applications. The calibration of current- to-voltage converters at a few input currents is not always sufficient to understand the linearity and the bias of a device. Many devices

AC stark shifts of dark resonances probed with Ramsey spectroscopy

November 16, 2018
Author(s)
James Wesley Y. Pollock, V. I. Yudin, Moshe Shuker, M. Y. Basalaev, A. V. Taichenachev, Xiaochi Liu, John E. Kitching, Elizabeth A. Donley
The off-resonant AC Stark shift for coherent population trapping (CPT) resonances probed with Ramsey spectroscopy is investigated experimentally and theoretically. Measurements with laser- cooled 87Rb atoms show excellent quantitative agreement with a

Spin relaxation of a donor electron coupled to interface states

November 16, 2018
Author(s)
Peihao Huang, Garnett W. Bryant
An electron spin qubit in a silicon donor atom is a promising candidate for quantum information processing because of its long coherence time. To be sensed with a single-electron transistor, the donor atom is usually located near an interface, where the

Tuning the Magnetic Ground State of Ce 1-x Yb x RhIn 5 by Yb Valence Fluctuations

November 16, 2018
Author(s)
S. Jang, N. Pouse, T. Keiber, B. D. White, S. M. Disseler, Jeffrey W. Lynn, J. C. Collini, M. Janoschek, F. Bridges, M. B. Maple
We characterize the properties of Ce 1-xYb xRhIn 5 single crystals with 0 less than or equal to} x less than or equal to} 1 using measurements of powder x-ray diffraction (XRD), energy dispersive x-ray spectroscopy (EDS), electrical resistivity, magnetic

Modeling Community Resilience: Update on the Center for Risk-Based Community Resilience Planning and the Computational Environment IN-CORE

November 15, 2018
Author(s)
John W. van de Lindt, Bruce Ellingwood, Therese P. McAllister, Paolo Gardoni, Daniel Cox, Walter G. Peacock, Harvey Cutler, Maria Dillard, Jong Lee, Lori Peek, Judith Mitrani-Reiser
Community resilience is often defined as the ability of a community to prepare for, absorb, and recover rapidly from a hazard event. In 2015, the U.S. National Institute of Standards and Technology (NIST) funded the Center for Risk-Based Community

3.5 GHz ESC Sensor Test Apparatus Using Field-Measured Waveforms

November 14, 2018
Author(s)
Raied Caromi, John Mink, Cosburn H. Wedderburn, Michael R. Souryal, Naceur El Ouni
This paper presents a framework and apparatus for laboratory testing of environmental sensing capability (ESC) sensors for the 3.5 GHz band. These sensors are designed to detect federal incumbent signals in the band so that the federal incumbent can be
