Conformance of Image Features to Classifier Assumptions

July 27, 2012
Author(s)
Julien M. Amelot, Peter Bajcsy, Mary C. Brady
Cell measurements are derived frequently from the results of pixel classification and contiguous region segmentation of microscopy images. Image segmentation is accomplished by classifying image pixels based on high dimensional image features computed from

Materials Challenges in Carbon Mitigation Technologies

April 24, 2012
Author(s)
Laura Espinal, Bryan D. Morreale
Thermochemical conversion of fossil fuels currently dominates the national and global energy portfolio, with the most notable being the stationary power production and transportation vehicles sectors. As global energy demand continues to increase

Transitory Temperatures of Organic-Film Coated Specimens under Outdoor Exposure

March 2, 2012
Author(s)
William C. Thomas, Christopher C. White, Walter E. Byrd
A mathematical model is presented and validated for predicting the temperature of thin polymeric films bonded to substrate materials. The National Institute of Standards and Technology provided specimen temperature and simultaneous weather data for tests

Standard Reactions for Comparative Rate Studies: Experiments on the Dehydrochlorination Reactions of 2 Chloropropane, Chlorocyclopentane and Chlorocyclohexane

November 23, 2011
Author(s)
Iftikhar A. Awan, Donald R. Burgess Jr., Wing Tsang, Jeffrey A. Manion
Single pulse shock tube studies of the thermal dehydrochlorination reactions (chlorocyclopentane → cyclopentene + HCl) and (chlorocyclohexane → cyclohexene + HCl) at temperatures of 843 to 1021 K and pressures of 1.4 to 2.4 bar have been carried out using

Data Dependency on Measurement Uncertainties in Speaker Recognition Evaluation

November 3, 2011
Author(s)
Jin Chu Wu, Alvin F. Martin, Craig S. Greenberg, Raghu N. Kacker
The National Institute of Standards and Technology (NIST) has been conducting an ongoing series of Speaker Recognition Evaluations (SRE). Speaker detection performance is measured using a detection cost function defined as a weighted sum of the

Development and Demonstration of a Method to Evaluate Bio-Sampling Strategies Using Building Simulation and Sample Planning Software

June 10, 2010
Author(s)
William S. Dols, Jayne B. Morrow, Andrew K. Persily, Brett Matzke, Landon Sego, Lisa Nuffer, Brent Pulsipher
response and recovery sampling approaches and technologies, the U.S. Department of Homeland Security (DHS), along with several other agencies, have simulated a biothreat agent release within a facility at Idaho National Laboratory (INL) on two separate

A 1D Spectral Image Validation/Verification Metric for Fingerprints

August 19, 2009
Author(s)
John M. Libert, John D. Grantham, Shahram Orandi
Image validation and verification are important functions in the acquisition of fingerprint images from live-scan devices and for assessing and maintaining the fidelity of fingerprint image databases. In addition to law enforcement, such databases are used

Development and Demonstration of a Method to Evaluate Bio-Sampling Strategies using Building Simulation and Sample Planning Software

June 1, 2009
Author(s)
William S. Dols, Jayne B. Morrow, Andrew K. Persily, Brett Matzke, Landon Sego, Lisa Nuffer, Brent Pulsipher
In an effort to validate and demonstrate response and recovery sampling approaches and technologies, the U.S. Department of Homeland Security (DHS), along with several other agencies, have simulated a bio-terrorist release within a facility at Idaho

Steering a Time Scale

December 1, 2008
Author(s)
Judah Levine
A time scale is a procedure for combining the data from an ensemble of clocks or frequency standards. The input data to the ensemble algorithm are generally the time (or frequency) differences between each of the members and the reference device for the

Accuracy Issues in Chemical and Dimensional Metrology in the SEM and TEM

October 16, 2008
Author(s)
J H. Scott
In this work computer simulations are used to understand systematic errors and accuracy concerns in both dimensional and chemical metrology in the scanning electron microscope (SEM) and transmission electron microscope (TEM).Multislice high-resolution TEM

Fire Induced Thermal and Structural Response of the World Trade Center Towers

September 26, 2008
Author(s)
Kuldeep R. Prasad, Anthony P. Hamins, Therese P. McAllister, John L. Gross
Over the past several years, there has been a resurgence of interest in studying the response of building structures to fires. Typically, the thermal loading for structural analysis of a building subject to fire is obtained from a standard time-temperature

Final Report on the Collapse of World Trade Center Building 7. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1A) ***DRAFT for Public Comments***

August 1, 2008
Author(s)
Sivaraj Shyam-Sunder, Richard G. Gann, William L. Grosshandler, Hai S. Lew, Richard W. Bukowski, Fahim Sadek, Frank W. Gayle, 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) investigation of the collapse of World Trade Center Building 7 (WTC 7), conducted under the National Construction Safety Team Act. This report describes how the fires

Shear Thinning Near the Critical Point of Xenon

April 17, 2008
Author(s)
Robert F. Berg, Michael R. Moldover, M Yao, G A. Zimmerli
We measured shear thinning, a viscosity decrease ordinarily associated with complex liquids, near the critical point of xenon. The data span the range of reduced shear rates: 0.001 < γτ < 700, where γτ is the shear rate scaled by the relaxation time τ of

Torsion rotation global analysis of the first three torsional states (mt = 0, 1, 2) and terahertz database for methanol

March 30, 2008
Author(s)
Jon T. Hougen, Li-Hong Xu, Jonathan M. Fisher, H. Y. Shi, J C. Pearson, Brian J. Drouin, G A. Blake, R. Braakman
Stimulated by recent THz measurements of the methanol spectrum in one of our laboratories, undertaken in support of NASA programs related to the Herschel Space Observatory (HSO) and the Atacama Large Millimeter Array (ALMA), we have carried out a global
