Improved Indifferentiability Security Bound for the JH Mode

February 15, 2015
Author(s)
Dustin Moody, Daniel C. Smith-Tone, Souradyuti Paul
Indifferentiability security of a hash mode of operation guarantees the mode's resistance against all generic attacks. It is also useful to establish the security of protocols that use hash functions as random functions. The JH hash function was one of the

Prediction and Validation of Diffusion Coefficients in a Model Drug Delivery System Using Microsecond Atomistic Molecular Dynamics Simulation and Vapor Sorption Analysis

October 21, 2014
Author(s)
Christopher Forrey, D M. Saylor, Joshua S. Silverstein, Jack F. Douglas, Eric Davis, Yossef A. Elabd
Diffusion of small to medium sized molecules in polymeric medical device materials underlies a broad range of public health concerns related to unintended leaching from or uptake into implantable medical devices. Knowledge of diffusion rates is thus

Does Your SEM Really Tell the Truth? How Would You Know? Part 2

May 30, 2014
Author(s)
Michael T. Postek, Andras Vladar, Premsagar P. Kavuri
The scanning electron microscope (SEM)has gone through a tremendous evolution to become indispensable for many and diverse scientific and industrial applications. The improvements have significantly enriched and augmented the overall SEM performance and

Final Report, National Institute of Standards and Technology (NIST) Technical Investigation of the May 22, 2011, Tornado in Joplin, Missouri

March 26, 2014
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 comparison of literature models for the oxidation of normal heptane

February 1, 2014
Author(s)
David A. Sheen, Wing Tsang
The development of detailed chemical kinetic models has proceeded unabated since the pioneering work of Dixon-Lewis and coworkers forty-five years ago. In that time, computational power has increased ten million-fold, and yet, we do not have a consensus on

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
