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

Workshop on Quantitative Tools for Condition Assessment of Aging Infrastructure

October 14, 2010
Author(s)
Ward L. Johnson, Thomas A. Siewert, Jessica Terry, Dat Duthinh, Mark Iadicola, William E. Luecke, Joseph D. McColskey
The Quantitative Tools for Condition Assessment of Aging Infrastructure Workshop was held May 4-5, 2010, in Boulder, Colorado. It was organized by a team of researchers within the National Institute of Standards and Technology s (NIST) Materials Science

Disaster Resilience: A Guide to the Literature

October 13, 2010
Author(s)
Stanley W. Gilbert
Although there is a great deal of high-quality information available on resilience-related topics hazard assessment, vulnerability assessment, risk assessment, risk management, and loss estimation as well as disaster resilience itself, there is no central

Dual frequency comb Fourier transform spectroscopy

October 12, 2010
Author(s)
Ian R. Coddington, William C. Swann, Nathan R. Newbury
Dual coherent frequency combs can be used in Fourier transform spectroscopy (FTS) to generate the full optical response of a sample with high frequency, and time, accuracy and resolution. The approach can be viewed equally well as a multiheterodyne

Further Studies of Bootstrap Variability for ROC Analysis on Large Datasets

October 11, 2010
Author(s)
Jin Chu Wu, Alvin F. Martin, Raghu N. Kacker
The nonparametric two-sample bootstrap is successfully applied to computing the measurement uncertainties in receiver operating characteristic (ROC) analysis on large datasets in areas such as biometrics, speaker recognition system, etc. To determine the

Localized Diffusive Motion on Two Different Time Scales in Solid Alkane Nanoparticles

October 11, 2010
Author(s)
Siao-Kwan Wang, E. Mamontov, Mengjun Bai, F.Y. Hansen, Haskell Taub, John R. Copley, Victoria Garcia Sakai, Goran Gasparovic, Timothy Jenkins, Madhu Sudan Tyagi, Kenneth W. Herwig, David B. Neumann, Wouter Montfrooij, U.G. Volkmann
High-energy-resolution quasielastic neutron scattering on three complementary spectrometers has been used to investigate molecular diffusive motion in solid nanoparticles of the alkane n-C 32H^66^. Nontranslational molecular diffusive motion in the plastic

Matching Observed Alpha Helix Lengths to Predicted Secondary Structure

October 11, 2010
Author(s)
Brian D. Cloteaux
Because of the complexity in determining the 3D structure of a protein, the use of partial information determined from experimental techniques can greatly reduce the overall computational expense. We investigate the problem of matching experimentally

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

Active Millimeter-Wave Imaging: Detection of Concealed Weapons

October 10, 2010
Author(s)
Randy Direen, David R. Novotny, Katherine MacReynolds
Images are constructed from data collected with a near- eld planar scannar and a network analyzer. Data are collected at millimeter-wave frequencies. This imaging system is used to image both metal and nonmetal objects.

An Inconvenient Truth About Tunneled Authentications

October 10, 2010
Author(s)
Katrin Hoeper, Lidong Chen
In recent years, it has been a common practice to execute client authentications for network access inside a protective tunnel. Man-in-the-middle (MitM) attacks on such tunneled authentications have been discovered early on and cryptographic bindings are

Link Relationship Measurements in Load-Modulated UHF RFID

October 10, 2010
Author(s)
Daniel G. Kuester, David R. Novotny, Jeffrey R. Guerrieri
This paper investigates the relative roles of the forward and reverse links in determining the operational range of passive UHF RFID systems. The relative importance the links are discussed first in the free field as a first-order model. We then present
