Series: NIST Interagency/Internal Report (NISTIR)
Report Number: .
Published: 1/1/2002
Authors: Carl R. Schultesiz, Kathleen M. Flynn, Stefan D Leigh

62. Dependence Characteristics of Face Recognition Algorithms
Published: 1/1/2002
Authors: Andrew L Rukhin, Patrick J Grother, P Jonathon Phillips, Stefan D Leigh, E M Newton, Nathanael A Heckert
Abstract: Nonparametric statistics for quantifying dependence between the output rankings of face recognition algorithms are described. Analysis of the archived results of a large face recognition study shows that even the better algorithms exhibit significan ...

63. Transformation, Ranking, and Clustering for Face Recognition Algorithm Performance
Published: 1/1/2002
Authors: Stefan D Leigh, Nathanael A Heckert, Andrew L Rukhin, P Jonathon Phillips, Patrick J Grother, E M Newton, M Moody, K Kniskern, S Heath
Abstract: The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank-based scores such a cumulative match score and receiver operating characteristic. This pape ...

64. Improving phase Doppler volume flux measurements in low data rate applications
Published: 8/1/2001
Authors: J F. Widmann, Cary Presser, Stefan D Leigh

65. A Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications
Series: Special Publication (NIST SP)
Report Number: 800-22
Published: 5/15/2001
Authors: Andrew L Rukhin, Juan Soto, James R Nechvatal, Miles E. Smid, Elaine B Barker, Stefan D Leigh, M Levenson, M Vangel, D L. Banks, Nathanael A Heckert, James F Dray Jr., S C. Vo
Abstract: [Superseded by SP 800-22 Revision 1a (April 2010):] This paper discusses some aspects of selecting and testing random and pseudorandom number generators. The outputs of such generat ...

66. Effect of Burst-Splitting Events on Phase Doppler Interferometry Measurements
Published: 2/1/2001
Authors: J F. Widmann, Cary Presser, Stefan D Leigh

67. Preparation and Certification of K-411 Glass Microspheres
Published: 12/1/2000
Authors: Ryna B. Marinenko, S V. Roberson, J S Small, Barbara B. Thorne, Douglas H. Blackburn, D Kauffman, Stefan D Leigh
Abstract: The production and characterization of NBS K-411 glass microspheres in the 3-40 um range for certification as a NIST Standard Reference Material (SRM) are described. EDS quantitative analysis and heterogeneity evaluations of the microspheres were ma ...

68. Reference Values for the Sensitivity of Standard Accelerometers Used in Intercomparisons
Published: 11/1/2000
Authors: David J. Evans, Stefan D Leigh, Beverly Francis Payne
Abstract: The National Metrology Institutes (NMIs) of 5 countries in North America and South America participated in an interlaboratory comparison involving the calibration of the magnitude of the sensitivity of 3 standard accelerometers. This comparison was p ...

69. Calibrating an Active Network Node
Published: 9/1/2000
Authors: Y Carlinet, V Galtier, Kevin L Mills, Stefan D Leigh, Andrew L Rukhin
Abstract: tive Network technology envisions deployment of virtual execution environments within network elements, so that nonhomogeneous processing can be applied to network traffic. For management purposes, each node must have a meaningful understanding of ...

70. Splicing Together Size Distributions to Increase the Size Range of a Phase Doppler Interferometer
Published: 7/1/2000
Authors: J F. Widmann, S R. Charagundla, Cary Presser, Stefan D Leigh
Abstract: A phase Doppler interferometer (PDI) was used to measure the intensity (i.e., the expected number of droplets measured per unit time) of a swirling methanol spray flame. Gaps observed in the data, which have been previously reported (McDonell and Sa ...
