Author(s)
Rolf L. Zeisler, Rick L. Paul, Rabia Oflaz, Lee L. Yu, Jacqueline L. Mann, William R. Kelly, Brian E. Lang, Stefan D. Leigh, Jeffrey A. Fagan
A material containing single-walled carbon nanotubes (SWCNTs) together with other carbon species, cata-lyst residues, and trace element contaminants has been prepared by the National Institute of Standards and Technology for characterization and

Lessons Learned in Evaluating DARPA Advanced Military Technologies

October 15, 2010
Author(s)
Craig I. Schlenoff, Brian A. Weiss, Michelle P. Steves
For the past six years, personnel from the National Institute of Standards and Technology (NIST) have served as the Independent Evaluation Team (IET) for two major DARPA programs. DARPA ASSIST (Advanced Soldier Sensor Information System and Technology) is

Methodology for evaluating Static six-degree-of-freedom (6DoF) Perception Systems

October 15, 2010
Author(s)
Tommy Chang, Tsai H. Hong, Joseph Falco, Michael O. Shneier, Milli Shah, Roger D. Eastman
In this paper, we apply two fundamental approaches toward evaluating a static, vision based, six-degree-of-freedom (6DoF) pose determination system that measures the position and orientation of a part. The first approach uses ground\-truth carefully

Properties for Accurate Gas Flow Measurements

October 15, 2010
Author(s)
John D. Wright
Accurate gas properties are needed to take full advantage of the low uncertainties provided by NIST’s Gas Flow Calibration Services. If a flowmeter user and NIST use different values for these properties (molecular mass, compressibility, density, viscosity

In Trust we Trust

October 14, 2010
Author(s)
Keith Miller, Jeff Voas, Phillip Laplante
The term trust has had a well understood definition for centuries. However after e-trust came along, and then cloud, where e-trust is not sufficient due to the non-touchability of a public cloud, the need to reconsider what trust means for a public cloud

Reliability of Embedded and Cyber-Physical Systems

October 14, 2010
Author(s)
Ram Chillarege, Jeff Voas
Cyber-physical systems feature a tight combination of a system's computational and physical elements. Understanding how to assess and design trustworthiness into these complex systems of systems remains an unsolved problem. This issue offers insights into
