SPIE 9639-49 Creation and Validation of Spectralon BRDF Targets & Standards

October 12, 2015
Author(s)
Catherine C. Cooksey, Gael Obein, Georgi T. Georgiev, Christopher Durell, Dan Scharpf, Greg McKee, Michelle L'Heureux
Spectralon is an extremely stable, near-perfect lambertian reflecting diffuser and calibration standard material that has been used by national labs, space, aerospace and commercial sectors for over two decades. New uncertainty targets of 2% on-orbit

Progress Towards Accurate Monitoring of Flue Gas Emissions

May 16, 2018
Author(s)
Aaron Johnson, Iosif Isaakovich Shinder, Michael R. Moldover, Joey Boyd, James Filla
The amounts of CO2 and other pollutants emitted by a coal-fired power plant are measured using a continuous emissions monitoring system (CEMS) permanently installed in the exhaust smokestack. The pollutant flux is the product of the pollutant's

Design and Capabilities of NISTs Scale-Model Smokestack Simulator (SMSS)

April 17, 2015
Author(s)
Aaron N. Johnson, Joey T. Boyd, Eric Harman, Mohammad M. Khalil, Jacob E. Ricker, Christopher J. Crowley, Rodney A. Bryant, Iosif I. Shinder
The amount of CO 2 emitted from a coal-fired power plant (CFPP) is measured by continuous emissions monitoring systems (CEMS) permanently installed in the exhaust smokestack. Both the CO 2 concentration and the bulk flow are continuously measured by CEMS

Towards a Reference Architecture for Archival Systems: Use Case With Product Data

April 28, 2014
Author(s)
Raphael Barbau, Joshua Lubell, Sudarsan Rachuri, Sebti Foufou
Long-term preservation of product data is imperative for many organizations. A product data archive should be designed to ensure information accessibility and understanding over time. Approaches such as the Open Archival Information System (OAIS) Reference

Automated Generation of AnIML Documents by Analytical Instruments

August 1, 2006
Author(s)
Alexander Roth, Ronny Jopp, R Schaefer, Gary W. Kramer
The scope of this project covers the storing of result data produced by generic laboratory devices during processing of analytical experiments, together with the data describing the examination methods and the audit trail using the AnIML (Analytical

Measurement Challenges and Metrology for Monitoring CO2 Emissions from Smokestacks Workshop Summary

January 20, 2016
Author(s)
Aaron N. Johnson, Rodney A. Bryant, Tamae M. Wong, James R. Whetstone, Eric Harman, Woong Kang, Keith A. Gillis, Hsin-Hung Lee, Iosif I. Shinder, Liang Zhang
On April 20-21, 2015, NIST hosted a workshop that, through measurement science, enabled the owners of stationary sources (primarily the electric power industry) and their regulatory agencies (federal and state) to better characterize greenhouse gas (GHG)

Improving Measurement for Smokestack Emissions - Workshop Summary

September 21, 2018
Author(s)
Rodney A. Bryant, Aaron N. Johnson, John D. Wright, Tamae M. Wong, James R. Whetstone, Michael R. Moldover, Iosif I. Shinder, Scott Swiggard, Chris Gunning, David Elam, Tom Martz, Eric Harman, David Nuckols, Liang Zhang, Woong Kang, Salvator Vigil
The complex flow conditions inherent in power plant smokestacks make accurate flow measurements challenging, which in turn limits the accuracy of hazardous emissions measurements. While stack composition measurements are assessed daily via comparison to a

Demystifying Accreditation A Framework for Accreditation of Forensic Units

October 1, 2023
Author(s)
Nicole Jones, Erin Forry, Donna J. Sirk
Accreditation is a formal recognition by an independent third party/accreditation body that a forensic service provider such as a laboratory, unit, or agency,a meets standards. A standard is a requirement or guideline used to ensure that a process or

Non-nulling Protocols for Fast, Accurate, 3-D Velocity Measurements in Stacks

July 28, 2023
Author(s)
Iosif Isaakovich Shinder, Aaron Johnson, James Filla, Vladimir B. Khromchenko, Michael R. Moldover, Joey Boyd, John D. Wright, John R. Stoup
We present protocols for making fast, accurate, 3-D velocity measurements in the stacks of coal-fired power plants. The measurements are traceable to internationally-recognized standards; therefore, they provide a rigorous basis for measuring and/or

NIST Programs to Advance Accurate, Internationally-Recognized Stack Emissions Measurements

September 15, 2016
Author(s)
Aaron Johnson, Iosif Isaakovich Shinder, Rodney A. Bryant, JohnPaul R. Abbott, Keith A. Gillis, Joey Boyd, James Filla, Michael R. Moldover
Accurate flow measurements are essential to quantify the amount of greenhouse gases (GHGs) and other pollutants emitted from power plant stacks. Although protocols have been developed, the uncertainty of stack flow measurements has not been documented. 

NIST Big Data Interoperability Framework: Volume 4, Security and Privacy

October 22, 2015
Author(s)
Wo L. Chang, Arnab Roy, Mark Underwood, NBD-PWG NIST Big Data Public Working Group
Big Data is a term used to describe the large amount of data in the networked, digitized, sensor-laden, information-driven world. While opportunities exist with Big Data, the data can overwhelm traditional technical approaches and the growth of data is
