Draft Final Report, National Institute of Standards and Technology (NIST) Technical Investigation of the May 22, 2011, Tornado in Joplin, Missouri (NIST NCSTAR 3) ***Draft for Public Comments***

November 21, 2013
Author(s)
Erica D. Kuligowski, Franklin T. Lombardo, Long Phan, Marc L. Levitan, David P. Jorgensen
This is the final report of the National Institute of Standards and Technology (NIST) investigation of the May 22, 2011, tornado in Joplin, Missouri, conducted under the National Construction Safety Team Act. This report describes the wind field of the

A New Metric for Latent Fingerprint Image Preprocessing

June 23, 2013
Author(s)
Mary Frances Theofanos, Andrew Dienstfrey, Brian Stanton, Haiying Guan
Although fingerprint recognition is a well-studied area, forensic fingerprint preprocessing based on computational theory is still a relatively new domain in need of further scientific study and development of standards of best practice. Latent fingerprint

Greenhouse Gas Emissions and Dispersion 1. Optimum placement of gas inlets on a building rooftop for the measurement of greenhouse gas concentrations

April 22, 2013
Author(s)
Kuldeep R. Prasad, Anthony Bova, James R. Whetstone, Elena Novakovskaia
Inverse atmospheric dispersion models are used to provide measurement-based, or “topdown”, estimates of greenhouse gas (GHG) emissions for comparison with input-based, or “bottom-up”, estimates. To minimize uncertainty, inverse estimates require accurate

Eddy Current Rail Inspection Using AC Bridge Techniques

February 26, 2013
Author(s)
Andrew D. Koffman, Bryan C. Waltrip, Yicheng Wang
AC bridge techniques commonly used for precision impedance measurements have been adopted to develop an eddy current sensor for rail defect detection. By using two detection coils instead of just one in a conventional sensor, we can balance out the large

A Restricted English for Constructing Ontologies (RECON)

July 10, 2012
Author(s)
Edward J. Barkmeyer Jr., Andreas K. Mattas
Verifying correctness of stated facts, rules, and term definitions for an industrial domain of work requires the contributions of experts in the domain. Conversely, use of automated reasoning technologies to assist in making industry decisions and

Database-Assisted Design for Wind: Multiple Points-in-Time Approach

December 22, 2011
Author(s)
Dong Hun Yeo
One of the problems encountered in the estimation of wind effects on high-rise structures is the development of combinations of such effects as translational responses and the rotational response to wind, and/or forces and moments at various cross sections

A Second-Generation NIST Gravimetric Hygrometer

April 1, 2010
Author(s)
Christopher W. Meyer, Joseph T. Hodges, Gregory E. Scace, James R. Whetstone, R W. Hyland
A second-generation primary hygrometer has been completed at the National Institute of Standards and Technology (NIST). A gravimetric hygrometer measures humidity by separating the water from the carrier gas using desiccants and afterwards independently

Optical Properties of Semiconductors

October 19, 2009
Author(s)
David G. Seiler, Stefan Zollner, Alain C. Diebold, Paul Amirtharaj
Rapid advances in semiconductor manufacturing and associated technologies have increased the need for optical characterization techniques for materials analysis and in-situ monitoring/control applications. Optical measurements have many unique and

Hyperspectral Image Compressive Projection Algorithm

June 1, 2009
Author(s)
Joseph P. Rice, Jorge E. Neira, David W. Allen
We describe a compressive projection algorithm and quantitatively assess its performance when used with a Hyperspectral Image Projector (HIP). The HIP is being developed by NIST for system-level performance testing of hyperspectral and multispectral

Testing and Analysis of Steel Beam-Column Assemblies under Column Removal Scenarios

May 6, 2009
Author(s)
Fahim Sadek, Joseph A. Main, Hai S. Lew, Stephen D. Robert, Vincent Chiarito
This paper presents an experimental and analytical assessment of the performance of steel beam-column assemblies with two types of moment-resisting connections under vertical displacement of a center column, simulating a column removal scenario. The
