ANSI/NIST-ITL 1-2011 Requirements and Conformance Test Assertions

September 16, 2011
Author(s)
Christofer J. McGinnis, Dylan J. Yaga, Fernando L. Podio
The current version of the ANSI/NIST-ITL standard "Data Format for the Interchange of Fingerprint, Facial & Other Biometric Information" is specified in two parts. Part 1, ANSI/NIST-ITL 1-2007, specifies the traditional format, and Part 2, ANSI/NIST-ITL 2

Evaluation of Ultra-Wideband Technology for use in 3D Locating Systems

September 28, 2010
Author(s)
Adam P. Kopp, Kamel S. Saidi, Hiam Khoury
A high-powered (5 Watt peak power) ultra-wideband (UWB) ranging system was evaluated for use as the basis for a 3-Dimensional (3D) locating system by comparing tracking results to a ground truth system. The UWB ranging system is composed of five ranging

Pulse Shape Discrimination for a Fast Neutron Detector

February 9, 2009
Author(s)
Kevin J. Coakley, Dominic F. Vecchia, Jeffrey S. Nico, B Fisher
We are developing a detector that uses liquid scintillator loaded with Li-6 for the efficient measurement of fast neutrons and their energy. Such a detector would have both scientific applications such as quantification of neutron energy spectra in

Modeling Human Behavior during Building Fires

December 30, 2008
Author(s)
Erica D. Kuligowski
Evacuation models, including engineering hand calculations and computational tools, are used to evaluate the level of safety provided by buildings during evacuation. Building designs, occupant procedures, and notification technology are based on the

Perspectives on the Future of Manufacturing Engineering

October 16, 2008
Author(s)
R Jackson
Technology-based competition is heating up everywhere. One economist uses the analogy-not of a race--but of a casino to convey the flavor of the global competition as well as the nature of the high-risk technology bets that companies confront. Three paths

Robustness Experiments with Two Variance Components

October 16, 2008
Author(s)
A Aviles
In many experimental settings, different types of factors affect the measured response. The factors that can be set independently of each other are called crossed factors. Nested factors cannot be set independently because the level of one factor takes on

Dynamic Phasor Measurement Unit Test System

June 1, 2007
Author(s)
Gerard N. Stenbakken, Ming Zhou
This paper presents the plans and progress towards the development of a dynamic phasor measurement unit (PMU) performance test system at NIST. We describe an algorithm for taking time-synchronized samples of single-phase voltage and current power signals

Biometrics Standards ? Rising to the Challenge of Technology Innovation

February 1, 2006
Author(s)
Fernando L. Podio
For decades, biometric technologies were primarily used in law enforcement applications. Currently, they are increasingly being required in multiple public and private sector applications worldwide to authenticate a person?s identity, secure national

Collapse of the World Trade Center Towers. Final Report. Federal Building and Fire Safety Investigation of the World Trade Center Disaster.

September 1, 2005
Author(s)
Standards and Technology National Institute of, Safety Team National Construction
This is the final report on the National Institute of Standards and Technology (NIST) investigation of the collapse of the World Trade Center (WTC) towers, conducted under the National Construction Safety Team Act. This report describes how the aircraft

Experiments and Modeling of Structural Steel Elements Exposed to Fire (Appendices D-G). Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5B)

September 1, 2005
Author(s)
Anthony P. Hamins, Alexander Maranghides, Kevin B. McGrattan, Erik L. Johnsson, Thomas J. Ohlemiller, Michelle K. Donnelly, Jiann C. Yang, George W. Mulholland, Kuldeep R. Prasad, S R. Kukuck, Robert Anleitner, Therese P. McAllister
Reconstructing the fires and their impact on structural components in the World Trade Center (WTC) buildings on September 11, 2001, requires extensive use of computational models. For the use of such models to be a viable investigative tool, it is

Final Report of the National Construction Safety Team on the Collapses of the World Trade Center Towers. Federal Building and Fire Safety Investigations of the World Trade Center Disaster (NIST NCSTAR 1) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Sivaraj Shyam-Sunder, Richard G. Gann, William L. Grosshandler, Hai S. Lew, Richard W. Bukowski, Fahim Sadek, Frank W. Gayle, Therese P. McAllister, Jason D. Averill, James R. Lawson, Harold E. Nelson, Stephen A. Cauffman
This is the final report on the National Institute of Standards and Technology (NIST) econstruction of the collapses of the World Trade Center (WTC) towers, the results of an investigation conducted under the National Construction Safety Team Act. This

Centrifugal Buoyancy Effects on the Linear Stability of Sprial Poiseuille Flow

February 1, 2004
Author(s)
David Cotrell, Geoffrey B. McFadden
For fluid flow in an annulus driven by the combination of an axial pressure gradient, rotation of the inner and outer cylinders, and a radial temperature gradient (spiral Poiseuille flow with a radial temperature gradient), we are investigating the

High-Throughput Analysis of Telomerase by Capillary Electrophoresis

January 1, 2003
Author(s)
Donald H. Atha, K Miller, A D. Sanow, J Xu, J L. Hess, O C. Wu, Wenhua Wang, S Srivastava, W E. Highsmith
The enzyme telomerase is expressed in 85-90% of all human cancers, but not in normal, non-stem cell somatic tissues. Clinical assays for telomerase in easily obtained body fluids would have great utility as non-invasive, cost-effective methods for the

Community-Scale Fire Spread

July 1, 2002
Author(s)
Ronald G. Rehm, Anthony P. Hamins, Howard R. Baum, Kevin B. McGrattan, D D. Evans
This paper addresses community-scale fires, which have also been called urban/wildland interface or intermix fires. These fires arise when wildlandfires invade the built environment and attack structures as well as wildland fuels. The prediction of the

Understanding Part Fabrication Errors in Closed-Loop Machining Systems

June 1, 2002
Author(s)
Herbert T. Bandy, Lawrence A. Welsch
This paper presents an analysis of part fabrication errors (part dimension and form deviations) in closed-loop machining systems. Modeling methods are used to situate error components in the context of other error components to clarify the effects of error
