A Rational Foundation for Software Metrology

January 20, 2016
Author(s)
David W. Flater, Paul E. Black, Elizabeth N. Fong, Raghu N. Kacker, Vadim Okun, Stephen S. Wood, David R. Kuhn
Much software research and practice involves ostensible measurements of software, yet little progress has been made on an SI-like metrological foundation for those measurements since the work of Gray, Hogan, et al. in 1996-2001. Given a physical object

Metrological challenges for measurements of key climatological observables, Part 4: Atmospheric relative humidity

December 15, 2015
Author(s)
Allan H. Harvey, J W. Lovell-Smith, Rainer Feistel, Olaf Hellmuth, Stephanie A. Bell, M Heinonen, J R. Cooper
Water in its three ambient phases plays the central thermodynamic role in the terrestrial climate system. Clouds control Earth’s radiation balance, atmospheric water vapour is the strongest “greenhouse” gas, and non-equilibrium relative humidity at the air

Poster:A Logic Based Network Forensics Model for Evidence Analysis

October 15, 2015
Author(s)
Anoop Singhal, Changwei Liu, Duminda Wijesekera
Modern-day attackers tend to use sophisticated multi-stage/multi-host attack techniques and anti-forensics tools to cover their attack traces. Due to the current limitations of intrusion detection and forensic analysis tools, reconstructing attack

Behavior of Axially Loaded Steel Short Columns Subjected to A Localized Fire

June 23, 2015
Author(s)
Chao Zhang, Lisa Y. Choe, Mina S. Seif
Current structural re design approaches are based on uniform heating conditions. Steel short columns in real buildings may be exposed to non-uniform heating conditions in accident res. This paper investigates numerically the behavior of steel short columns

Quantitative Imaging of Clinker and Cement Microstructure

April 15, 2015
Author(s)
Paul E. Stutzman, Jeffrey W. Bullard, Pan Feng
The combination of scanning electron microscopy (SEM) with X-ray microanalysis and image processing provides a powerful ability to image and quantify microstructural features of con- struction materials. This document provides guidance for collecting

Privacy Amplification in the Isolated Qubits Model

April 14, 2015
Author(s)
Yi-Kai Liu
Isolated qubits are a special class of quantum devices, which can be used to implement tamper-resistant cryptographic hardware such as one-time memories (OTM's). Unfortunately, these OTM constructions leak some information, and standard methods for privacy

Metrology for comparison of displacements at the picometer level

July 31, 2014
Author(s)
Jack A. Stone Jr., Patrick F. Egan, Jay H. Hendricks, Gregory F. Strouse, Douglas A. Olson, Jacob E. Ricker, Gregory E. Scace, Donavon Gerty
An apparatus capable of comparing displacements with picometer accuracy is currently being designed at NIST. In principle, we wish to compare one displacement in vacuum to a second, equal displacement in gas, in order to determine gas refractive index. If
