Author(s)
Lee L. Yu, William C. Davis, Rabia Oflaz, Gregory C. Turk, Jeff M. Jarrett, Liza Valentin, Benjamin C. Blount, Dennis D. Leber, Eric L. Kilpatrick
Perchlorate, an inorganic anion, has recently been recognized as an environmental contaminant by the U.S. Environmental Protection Agency (EPA). Assessment of human exposure to perchlorate requires measurement of the anion in urine. Although the

Incorporating Attribute Value Uncertainty into Decision Analysis

May 28, 2012
Author(s)
Dennis D. Leber, Jeffery W. Herrmann
Attribute value uncertainty is present in a decision when the consequences are characterized by uncertain estimates of the underlying, unknown true values. Attributes defined based upon measurement data, experimental data, or survey data are subject to

Objective Evaluation of Imager Performance

December 1, 2011
Author(s)
Francine K. Amon, Dennis D. Leber, Nicholas Paulter
We describe a method by which the evaluation and characterization of the performance of an imager can be done objectively and scientifically, that is, without routine operator interpretation. Although this method is demonstrated herein for passive long

May 2, 2011
Author(s)
Cynthia H. Reed, Daniel V. Samarov, Dennis D. Leber, Zhe Liu, John Little
The National Institute of Standards and Technology (NIST) and Virginia Tech (VT) are developing a volatile organic compound (VOC) reference material to validate product emissions chamber testing. To verify the storage method of the material and determine

Developing a Diffusive Reference Material for VOC Emissions Testing: Pilot Interlaboratory Study

February 25, 2011
Author(s)
Cynthia H. Reed, Zhe Liu, Jennifer Benning, Steven Cox, Daniel V. Samarov, Dennis D. Leber, Al Hodgson, Stephany Mason, Doyun Won, John C. Little
In order to improve the reliability of product emissions testing and labeling, the National Institute of Standards and Technology (NIST) and Virginia Tech (VT) have created a program to develop reference materials with independently known emission rates

Analysis of Three Different Regression Models to Estimate the Ballistic Performance of New and Environmentally Conditioned Body Armor

February 14, 2011
