James R. Matey, Su L. Cheng, Patrick J. Grother, Mei L. Ngan, George W. Quinn, Elham Tabassi, Craig I. Watson
We present ROC baseline data to support the recommendations in Matey et al [6].

Improving Security and Software Management through the use of SWID Tags

July 13, 2016
Author(s)
David A. Waltermire, Larry Feldman, Gregory A. Witte
This bulletin summarized the information presented in NISTIR 8060, "Guidelines for the Creation of Interoperable Software Identification (SWID) Tags". The publication provides an overview of the capabilities and usage of SWID tags as part of a

Is the Factor of 10 Still Applicable Today?

July 13, 2016
Author(s)
Simone N. Gittelson, John S. Buckleton
The assignment of the weight of DNA evidence depends on a number of factors (allele probability estimates, the population genetic model used, the value of the coancestry coefficient, etc.). One of these factors is the allele probability estimates from a

Synchrotron 4-dimensional imaging of two-phase flow through porous media

July 13, 2016
Author(s)
Felix H. Kim, D. Penumadu, P. Patel, X. Xiao, E. J. Garboczi, Shawn P. Moylan, M A. Donmez
Near real-time visualization of complex two-phase flow in a porous medium was demonstrated with dynamic 4D (3D + time) imaging at the 2-BM beam line of the Advanced Photon Source (APS) at Argonne National Laboratory. Advancing fluid fronts through tortuous

Mobile Manipulator Performance Measurement Towards Manufacturing Assembly Tasks

July 12, 2016
Author(s)
Roger V. Bostelman, Sebti Foufou, Steven A. Legowik, Tsai H. Hong
Mobile manipulator performance measurement research is relatively minimal as compared to that of robot arms. Measurement methods, such as optical tracking systems, are useful for measuring the performances of mobile manipulators, although at a much higher

Field-free switching of perpendicular magnetization through spin-orbit torque in antiferromagnet/ferromagnet/oxide structures

July 11, 2016
Author(s)
Young-Wan Oh, Young Min Kim, Hae Yeon Lee, Kyeong-Dong Lee, Chang-Geun Yang, Eun-Sang Park, Ki-Sueng Lee, Kyoung-Whan Kim, Hyun-Woo Lee, Kyung-Jin Lee, Byong-Guk Park
Spin-orbit torques (SOTs), spin-transfer torques caused by spin-orbit coupling, allow highly efficient manipulation of magnetization. To date, most experiments have utilized non-magnetic heavy metals as a source of SOT. Recent prediction of the anomalous

Workshop on Lunar Calibration for Remote Sensing

July 11, 2016
Author(s)
Claire E. Cramer
Tracking climate variables at the levels of precision and accuracy required to detect global change requires satellite sensors to make highly consistent measurements that can be compared to measurements made at different times and with different

2 V Pulse-Driven Josephson Arbitrary Waveform Synthesizer

July 10, 2016
Author(s)
Nathan E. Flowers-Jacobs, Alain Rufenacht, Anna E. Fox, Paul D. Dresselhaus, Samuel P. Benz
We created a Josephson Arbitrary Waveform Synthesizer (JAWS) with a root-mean-square (rms) output magnitude of 2 V. This system is composed of two 1 V chips operating on a cryocooler. By controlling the relative phase of the two chips’ output voltage, we

Fabrication of High Value Standard Resistors for ICE-LMVE

July 10, 2016
Author(s)
Dean G. Jarrett, Isabel Castro, Marlin E. Kraft
In Costa Rica, the Laboratorio Metrológico de Variables Eléctricas (LMVE) at the Instituto Costarricense de Electricidad (ICE) develops and improves measurement capabilities to promote and support the industrial innovation and development in the country

First mass measurements with the NIST-4 watt balance

July 10, 2016
Author(s)
Darine El Haddad, Leon S. Chao, Frank C. Seifert, David B. Newell, Jon R. Pratt, Stephan Schlamminger
In the past four years, we have constructed a new watt balance at the National Institute of Standards and Technology (NIST), with the goal to realize the unit of mass after the redefinition of the International System of Units, expected to occur in 2018

Improvement of Leakage Resistance of PJVS for NIST-4 Watt Balance Experiment

July 10, 2016
Author(s)
Yi-hua D. Tang, Frank C. Seifert, Stephan Schlamminger
A Programmable Josephson Voltage Standard (PJVS) system is used for the voltage measurements in NIST-4 Watt balance experiment. It is critical to enhance the leakage resistance of the PJVS in order to achieve the uncertainty of voltage measurements better

Model-based engineering for the integration of manufacturing systems with advanced analytics

July 10, 2016
Author(s)
David Lechevalier, Anantha Narayanan Narayanan, Sudarsan Rachuri, Sebti Foufou, Yung-Tsun Lee
To employ data analytics effectively and efficiently on manufacturing systems, engineers and data scientists need to collaborate closely to bring their domain knowledge together. In this paper, we introduce a domain-specific modeling approach to integrate

Quantum Hall Resistance Traceability for the NIST-4 Watt Balance

July 10, 2016
Author(s)
Dean G. Jarrett, Randolph Elmquist, Marlin E. Kraft, George R. Jones Jr., Shamith Payagala, Frank Seifert, Stephan Schlamminger, Darine El Haddad
Scaling from the quantum Hall resistance to 100 Ω standard resistors used by the NIST-4 Watt Balance involves multiple resistance standards and bridges to provide the lowest possible uncertainty. Described here is the infrastructure and procedures
