61. Changes
Topic: Math
Published: 1/3/2011
Author: Isabel M Beichl

62. Recommendation for Password-Based Key Derivation Part I: Storage Applications
Series: Special Publication (NIST SP)
Report Number: 800-132
Topic: Math
Published: 12/22/2010
Authors: Meltem Sonmez Turan, Elaine B Barker, William Edward Burr, Lidong Chen
Abstract: This Recommendation specifies techniques for the derivation of master keys from passwords or passphrases to protect stored electronic data or data protection keys.

63. Assessing differences between results determined according to the Guide to the Expression of Uncertainty in Measurement
Series: Journal of Research (NIST JRES)
Topic: Math
Published: 12/1/2010
Authors: Raghu N Kacker, Ruediger Kessel, Klaus-Dieter Sommer
Abstract: When the data consist of multiple results of measurement for a common measurand, often one needs to determine whether the results agree with each other. A result of measurement based on the Guide to the Expression of Uncertainty in Measurement (GUM) ...

64. Derivation of Isosceles Trapezoidal Distribution
Topic: Math
Published: 12/1/2010
Authors: Raghu N Kacker, James F Lawrence
Abstract: It is known that, if the mid-point of a rectangular distribution is specified, the half-width is inexactly known, and the state of knowledge about the half-width may be represented by a narrower rectangular distribution then the resulting distributio ...

65. Bochner Subordination, Logarithmic Diffusion Equations, and Blind Deconvolution of Hubble Space Telescope Imagery and Other Scientific Data
Topic: Math
Published: 11/30/2010
Author: Alfred S Carasso
Abstract: Generalized Linnik processes and associated logarithmic diffusion equations can be constructed by appropriate Bochner randomization of the time variable in Brownian motion and the related heat conduction equation. Remarkably, generalized Linnik char ...

66. Biological Cell Feature Identification by a Modified Watershed-Merging Algorithm
Series: NIST Interagency/Internal Report (NISTIR)
Topic: Math
Published: 11/24/2010
Authors: David E. Gilsinn, Kiran Bhadriraju, John T Elliott
Abstract: Biological cells are composed of many subsystems and organelles. The subsystem called the cytoskeleton is composed of long rod-shaped structures. They give the cell form and help attach the cell to the substrate and neighbors. One of the filaments is ...

67. Bicubic B-Spline Surface Approximation of Invariant Tori
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7731
Topic: Math
Published: 10/20/2010
Authors: Sita Ramamurti, David E. Gilsinn
Abstract: The invariant torus of a coupled system of Van der Pol oscillators is approximated using bicubic B-splines. The paper considers the case of strong nonlinear coupling. In particular, the shapes of invariant torii for the Van der Pol coupling parameter ...

68. A New Analysis of the False-Positive Rate of a Bloom Filter
Topic: Math
Published: 10/15/2010
Authors: Ken Christensen, Allen L Roginsky, Miguel Jimeno
Abstract: A Bloom filter is a space-efficient data structure used for probabilistic set membership testing. When testing an object for set membership, a Bloom filter may give a false positive. The analysis of the false positive rate is key to understanding the ...

69. Modelling Type Ia Supernova Light Curves
Topic: Math
Published: 9/15/2010
Authors: Bert W Rust, Dianne M O'Leary, Katharine M Mullen
Abstract: Type Ia supernova light curves are characterized by a rapid rise from zero luminosity to a peak value, followed by a slower quasi-exponential decline. The rise and peak last for a few days, while the decline persists for many months. It is widely b ...

70. Metrological Compatibility and Statistical Consistency
Topic: Math
Published: 9/5/2010
Authors: Raghu N Kacker, Ruediger Kessel, Klaus-Dieter Sommer, Xin Bian
Abstract: The traditional concept of consistency in multiple evaluations of the same measurand is statistical. The statistical view of consistency does not match the modern view of uncertainty in measurement; in particular, it does not apply to the results of ...
