Face Recognition Algorithms surpass humans matching faces across changes in illumination

May 15, 2007
Author(s)
P. Jonathon Phillips, Alice J. O'Toole, Fang Jian, Julianne Ayadd, Nils Penard, Herve Abdi
We compared the accuracy of eight state-of-the-art face recognition algorithms with human performance on the same task. Humans and algorithms determined whether two face images, taken under different illumination conditions, were pictures of the same

Authenticating Mobile Device Users Through Image Selection

May 19, 2004
Author(s)
Wayne Jansen
Adequate user authentication is a persistent problem, particularly with mobile devices such as Personal Digital Assistants (PDAs), which tend to be highly personal and at the fringes of an organization's influence. Yet these devices are being used

Network Security Testing

Author(s)
Shirley M. Radack
This ITL Bulletin summarizes NIST Special Publication 800-42, Guideline on Network Security Testing, by John Wack, Miles Tracy, and Murugiah Souppaya, which assists organizations in testing their Internet-connected and operational systems. The guide

Large-Scale Modeling of Fire Suppression with Water Sprays

September 2, 2003
Author(s)
Kevin B. McGrattan
The mechanisms underlying fire suppression by water can bedivided into gas and solid phase phenomena. Numerical models ofthese phenomena are dependent on the level of detail given to thecombustion and the fuel pyrolysis processes.Presently, models of gas

SEM Sentinel-SEM Performance Measurement System

August 1, 2001
Author(s)
Bradley N. Damazo, Andras Vladar, Alice V. Ling, Alkan Donmez, Michael T. Postek, Crossley E. Jayewardene
This paper describes the design and implementation of a system for monitoring the performance of a critical dimension measurement scanning electron microscope (CD-SEM). Experiments were performed for tests involving diagnosis of the vacuum system and

E Roback
[Prepared for the CIO Council's Security, Privacy, and Critical Infrastructure Committee] The Federal Information Technology (IT) Security Assessment Framework (or Framework) provides a method for agency officials to 1) determine the current status of

Representation of Axes for Geometric Fitting

December 1, 1996
Author(s)
Ted Hopp
We review methods for representing geometric axes in three dimensions and discuss why these methods have undesirable properties for geometric fitting applications. We then describe a new representation that seems better suited for use in problems of

Visualization of Structural Behavior under Fire

August 12, 2009
Author(s)
Dilip K. Banerjee, William J. Hess, Thomas M. Olano, Judith E. Terrill, John L. Gross
An integrated environment was created to study the interaction among fire, heat transfer, and structural deformation from a typical room fire. The fire, thermal, and structural data were linked with a separate 3-D visualization capability, to provide the

Developing an Analysis of Threats to Voting Systems: Workshop Summary

October 7, 2005
Author(s)
Allan C. Eustis
The Help America Vote Act (HAVA) of 2002 has given NIST a key role in helping to realize nationwide improvements in voting systems by January 2006. NIST research activities authorized by HAVA include the security of computers, computer networks, and

Design of an intelligent PYTHON code to run coupled and license-free finite-element and statistical analysis software for calibration of near-field scanning microwave microscopes

October 2, 2019
Author(s)
Jeffrey T. Fong, N. Alan Heckert, James Filliben, Pedro V. Marcal, Samuel Berweger, Thomas Mitchell (Mitch) Wallis, Pavel Kabos
To calibrate near-field scanning microwave microscopes (NSMM) for defect detection and characterization in semiconductors, it is common to develop a parametric finite element analysis (FEA) code to guide the microscope user on how to optimize the settings
