IREX IV: Part 1, Evaluation of Iris Identification Algorithms

July 11, 2013
Author(s)
George W. Quinn, Patrick J. Grother, Mei L. Ngan, James R. Matey
IREX IV aims to provide a fair and balanced scientific evaluation of the performance of automated iris recognition algorithms. IREX IV evaluated the performance of 66 identification (i.e. one-to-many matching) algorithms submitted by 12 companies and

IREX VI - Temporal Stability of Iris Recognition Accuracy

July 11, 2013
Author(s)
Patrick J. Grother, James R. Matey, Elham Tabassi, George W. Quinn, Michael Chumakov
Background: Stability is a required definitional property for a biometric to be useful. Quantitative statements of stability are operationally important as they dictate re-enrollment schedules e.g. of a face on a passport. Ophthalmologists consider the

Multi-resonant plasmonic nanodome arrays for label-free biosensing applications

July 10, 2013
Author(s)
Charles J. Choi, Stephen Semancik
The characteristics and utility of plasmonic nanodome arrays capable of supporting multiple resonance modes are described. A low-cost, large-area replica molding process is used to produce, on flexible plastic substrates, two-dimensional periodic arrays of

On the bending strength of single-crystal silicon theta-like specimens

July 10, 2013
Author(s)
Rebecca R. Kirkpatrick, William Alexander Osborn, Michael S. Gaither, Richard S. Gates, Frank W. DelRio, Robert F. Cook
A new theta geometry was developed for micro-scale bending strength measurements. The new "gap" theta specimen was a simple modification of the arch theta specimen that enabled micro-scale tensile testing. The gap theta was demonstrated here on single

Toward a reference architecture for archival systems

July 10, 2013
Author(s)
Raphael Barbau, Joshua Lubell, Sudarsan Rachuri, Sebti Foufou
Long-term preservation of product data is imperative for many organizations. A product data archive should be designed to ensure information accessibility and understanding over time. Approaches such as the Open Archival Information System (OAIS) Reference

Uncertainty Machine --- User's Manual

July 10, 2013
Author(s)
Antonio M. Possolo, Thomas V. Lafarge
NIST's Uncertainty Machine is a software application to evaluate the measurement uncertainty associated with an output quantity defined by a measurement model of the form y = f(x[1],...,x[n]), where the real-valued function f is specified fully and

A method for the analysis of behavioural uncertainty in evacuation modelling

July 9, 2013
Author(s)
Enrico Ronchi, Paul A. Reneke, Richard D. Peacock
Evacuation models generally include the use of distributions or probabilistic variables to simulate the variability of possible human behaviours. A single model setup of the same evacuation scenario may therefore produce a distribution of different

Broadband S-parameter characterization of a DC-SQUID amplifier

July 9, 2013
Author(s)
Leonardo M. Ranzani, Lafe F. Spietz, Jose A. Aumentado
In this work we characterize the 2-port scattering parameters of a superconducting quantum interference device (DC-SQUID) ampli er at 20 mK in the 2{8 GHz band. The measurement reference plane is positioned on a 6.25 microstrip line situated directly at

Economic Case Study: The Impact of NSTIC on the Internal Revenue Service

July 9, 2013
Author(s)
Gregory C. Tassey
The National Strategy for Trusted Identities in Cyberspace (NSTIC) offers a vision of more secure, efficient, and cost-effective authentication through widespread use of robust third-party credentials standardized to a national strategy. If successful
