Materials Challenges in Carbon Mitigation Technologies

April 24, 2012
Author(s)
Laura Espinal, Bryan D. Morreale
Thermochemical conversion of fossil fuels currently dominates the national and global energy portfolio, with the most notable being the stationary power production and transportation vehicles sectors. As global energy demand continues to increase

Pivotal Methods in the Propagation of Distributions

April 24, 2012
Author(s)
Chih-Ming Wang, Jan Hannig, Hariharan K. Iyer
We propose a method for assigning a probability distribution to an input quantity. The distribution is used in the Monte Carlo method for uncertainty evaluation. The proposed method provides an alternative to other methods, such as the principle of maximum

PV-MCT working standard radiometer

April 24, 2012
Author(s)
George P. Eppeldauer, Vyacheslav B. Podobedov
Sensitive infrared working-standard detectors with large active area are needed to extend the signal dynamic range of the National Institute of Standards and Technology (NIST) pyroelectric transfer-standards used for infrared spectral power responsivity

A review of fire blocking technologies for soft furnishings

April 23, 2012
Author(s)
Shonali Nazare, Rick D. Davis
Fire barrier fabrics are expected to play an increasingly important role in complying with existing and proposed soft furnishing flammability regulations. The number of commercial fire blocking technologies is large in order to accommodate the vast

LDPC Error Correction in the Context of Quantum Key Distribution

April 23, 2012
Author(s)
Anastase Nakassis
Secret keys can be established through the use of Quantum channels monitored through classical channels which can be thought of as being error free. Because many of the feasible implementation of the quantum channel are subject to erasures –often massive-

A Proteomics Performance Standard to Support Measurement Quality in Proteomics

April 21, 2012
Author(s)
Ashley B. Green, David M. Bunk, Paul A. Rudnick, Karen W. Phinney, Lisa E. Kilpatrick
The emergence of mass spectrometry-based proteomic platforms as a prominent technology utilized in biochemical and biomedical research has increased the need for high-quality MS measurements. To address this need, NIST Reference Material (RM) 8323 Yeast

Automated Clock Comparisons and Time Scale Generation in the SIM Region

April 21, 2012
Author(s)
Michael A. Lombardi, J. Mauricio Lopez-Romero, Nelida Diaz-Munoz
The second, the base unit of time interval in the International System, is defined in terms of the two hyperfine states of the Cesium atom ground energy level. This definition has so far served the metrology community well, and the uncertainty of the best

Combinatorial Methods for Event Sequence Testing

April 21, 2012
Author(s)
D. Richard Kuhn, James M. Higdon, James F. Lawrence, Raghu N. Kacker, Yu Lei
Many software testing problems involve sequences. This paper presents an application of combinatorial methods to testing problems for which it is important to test multiple configurations, but also to test the order in which events occur. For example, the
