Recommendations for Collecting, Curating, and Re-Using Manufacturing Data

July 16, 2020
Author(s)
Moneer M. Helu, Thomas D. Hedberg Jr.
This report provides general recommendations for collecting, curating, and re-using manufacturing data from both additive and subtractive processes. The intended audience includes researchers, technical-assessment personnel, and end-users who would like to

Production Method for Machine-Readable Manufacturing Data Standards

June 19, 2020
Author(s)
Tim Shinbara, Russell Waddell, Moneer Helu
Standards to represent and manage manufacturing data are proliferating as industry rapidly digitizes. The existing global standards development paradigm for manufacturing data needs to shift to digital tools and workflows that produce machine-readable

Improving patient outcomes with regenerative medicine: How to move the needle forward in cell manufacturing, standards, 3D bioprinting, AI enabled automation, education and training

Regenerative Medicine Manufacturing Society (RMMS), is the first and only professional society dedicated specifically towards advancing manufacturing solutions for the field of regenerative medicine. RMMS' vision is to provide greater patient access to

CERTIFICATION OF SRM 640f LINE POSITION AND LINE SHAPE STANDARD FOR POWDER DIFFRACTION

May 31, 2020
Author(s)
David R. Black, Marcus Mendenhall, Albert Henins, James Filliben, James Cline
The National Institute of Standards and Technology (NIST) certifies a suite of Standard Reference Materials (SRMs) to be used to evaluate specific aspects of instrument performance of both X-ray and neutron powder diffractometers. This report describes SRM

Advanced Temperature-Control Chamber for Resistance Standards

April 10, 2020
Author(s)
Shamith Payagala, Alireza Panna, Albert Rigosi, Dean G. Jarrett
Calibration services for resistance metrology have continued to advance their capabilities and establish new and improved methods for maintaining standard resistors. Despite the high quality of these methods, there still exist inherent limitations to the

Workshop on Smart Grid Interoperability Testing and Certification

January 31, 2020
Author(s)
Cuong T. Nguyen, Avi M. Gopstein
New smart grid architectures, devices, systems, and applications require extensive data exchange, necessitating well-defined interfaces to transfer and translate this data across the grid. Clarifying the protocols and data performance requirements across

ENTHALPY OF FORMATION OF AQUEOUS HYDROFLUORIC ACID: REVISION NEEDED?

November 7, 2019
Author(s)
Yauheni Paulechka, Andrei F. Kazakov
Accurate enthalpies of formation of hydrofluoric acid in the gas and liquid states as well as in aqueous solutions are critical for reduction and interpretation of combustion calorimetry data for fluorinated compounds. Analysis of current recommendations

Optical-Fiber Power Meter Comparison between NIST and LAMETRO

November 1, 2019
Author(s)
Johnny Jimenez, Maria Ugalde, John H. Lehman, Igor Vayshenker
We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Laboratorio de Metrologia, Instituto Costarricense de Electricidad (LAMETRO-ICE, COSTA RICA) for optical fiber-based

Degradation of sunglasses filters after long-term irradiation within solar simulator

September 18, 2019
Author(s)
Deborah Jacobs, Mauro Masili, Fernanda O. Duarte, Liliane Ventura, Christopher C. White
In our previous investigations on sunglasses standards, limits and requirements have been suggested for ocular safety. In this paper we evaluate the degradation of the lenses (category and ultraviolet protection) as sunglasses are exposed to solar

The Molybdenum K-shell X-ray Emission Spectrum

September 18, 2019
Author(s)
Marcus H. Mendenhall, Lawrence T. Hudson, Csilla I. Szabo-Foster, Albert Henins, James P. Cline
Abstract We present newly measured spectra of the X-ray emission of a molybdenum metal anode subject to electron bombardment, using a very high dispersion silicon double-crystal spectrometer. The measurement includes the dipole-allowed KL, KM, and KN

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
