Comments on 'Bayesian evaluation of comparison data' by Ignacio Lira

January 1, 2007
Author(s)
Raghu N. Kacker, Blaza Toman
A recent paper by Ignacio Lira in Metrologia 43 (2006) S231-S234 addresses a well-known problem in combining information from interlaboratory evaluations. Lira presents an expression, which he claims to be the kernel of a Bayesian posterior probability

Uncertainty Analysis for Virtual Cement Measurement

September 13, 2006
Author(s)
Blaza Toman, Adriana Hornikova, Robert C. Hagwood, Hung-Kung Liu, Nien F. Zhang, Edward J. Garboczi, Jeffrey W. Bullard
Virtual measurements are the outputs of well-defined mathematical models based on theoretical principles and simulation algorithms. The VCCTL (Virtual Cement and Concrete Testing Laboratory) is a software system built by the Material and Construction

New Guidelines for d13C Measurements

April 1, 2006
Author(s)
T Coplen, W A. Brandt, M Gehre, Manfred Groning, HAJ Meijer, Blaza Toman, Jennifer R. Verkouteren
Consistency of 13C measurements can be improved 39-47% by anchoring the 13C scale with two isotopic referencematerials differing substantially in 13C/12C. It isrecommended that 13C values of both organic andinorganic materials be measured and expressed

Consistency of D 13 C Measurements Improved

February 1, 2006
Author(s)
T B. Copelen, W Brand, M Gehre, M Groening, HAJ Meijer, Blaza Toman, R. Michael Verkouteren
We present state-of-the-art measurements and data evaluation methods to show that the consistency of carbon isotope ratio measurements can be improved 39 % to 47 % by anchoring the measurement scale with two isotopic reference materials differing in carbon
