Interlaboratory Comparisons

December 10, 2007
Author(s)
William F. Guthrie
An interlaboratory comparison for a measurement procedure is an exercise carried out by a group of laboratories to compare their performance or assess a measurement standard. Interlaboratory comparisons are typically used for one of three main purposes, to

Validation of Two-Sample Bootstrap in ROC Analysis on Large Datasets Using AURC

October 11, 2010
Author(s)
Jin Chu Wu, Alvin F. Martin, Raghu N. Kacker
Sampling variability can result in uncertainties of measures. The nonparametric two-sample bootstrap method has been used to compute uncertainties of measures in receiver operating characteristic (ROC) analysis on large datasets, such as the standard error

Test method for measuring the electrical output of electroshock weapons

July 25, 2016
Author(s)
Nicholas G. Paulter Jr., David M. Jenkins, Norimitsu Ichikawa, Michael Leonesio
Electroshock weapons (ESWs) have become a ubiquitous component of weapons used in the arsenal of domestic law enforcement (LE) agencies and the military around the world. It is a major contributor to the escalation of force policies and procedures of many

Size-Monodisperse Metal Nanoparticles Via Hydrogen-Free Spray Pyrolysis

April 3, 2002
Author(s)
Jung Hyeun Kim, Thomas A. Germer, George Mulholland, S H. Ehrman
Pure copper nanoparticles were produced using a co-solvent approach avoiding use of hydrogen or other reducing gas. Compared with the particles formed without the co-solvent, the addition of alcohol has a significant effect in preventing oxidation, which
