131. On Use of Bayesian Statistics to Make Guide to the Expression of Uncertainty in Measurement Consistent
Topic: Math
Published: 9/1/2003
Authors: Raghu N Kacker, Albert W Jones
Abstract: The Guide to the Expression of Uncertainty in Measurement recommends a standardized way of expressing uncertainty in measurement and provides a comprehensive approach for combining information to evaluate uncertainty in all kinds of measurements in s ...

132. An Optimization Approach to Multiple Sequence Alignment
Topic: Math
Published: 7/1/2003
Authors: Fern Y Hunt, Anthony J Kearsley, H H Wan
Abstract: The problem of multiple sequence alignment is recast as an optimization problem using Markov decision theory. One seeks to minimize the expected or average cost of alignment subject to data-derived constraints. In this setting the problem is equiva ...

134. Separating Signal From Noise in Global Warming
Topic: Math
Published: 3/12/2003
Author: Bert W Rust
Abstract: One argument often used against global warming is that the global temperature record is too noisy to allow a clear determination of the signal. This paper presents two models for the signal which suggest that: (1) the warming is accelerating, (2) th ...

137. Algorithms and Codes for the Macdonald Function: Recent Progress and Comparisons
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6596
Topic: Math
Published: 2/1/2003
Authors: B R Fabijonas, Daniel W Lozier, J M Rappoport
Abstract: The modified Bessel function K^di{nu}^{chi}, also known as the Macdonald function, finds application in the Kontorovich-Lebedev integral transform when {chi} and {nu} are real and positive. In this paper, a comparison of three codes for computing th ...

138. Dealing with Degeneracy in Triangulation
Topic: Math
Published: 11/1/2002
Authors: Francis Sullivan, Isabel M Beichl
Abstract: This is a tutorial article on a quick method for dealing with degeneracy in geometric computations with specific reference to triangulation. The type degeneracy targeted by this article that of four or more points on a circle and five or more points ...

139. Lattice Matching (LM)-Prevention of Inadvertent Duplicate Publications of Crystal Structures
Series: Journal of Research (NIST JRES)
Topic: Math
Published: 10/1/2002
Author: Alan D. Mighell
Abstract: Lattice-matching techniques have proved to be an extremely effective for the identification of unknown crystalline materials. A commonly employed lattice-matching strategy is based on matching the reduced cell of an unknown against a database of know ...

140. Reconstructing Images of Bar Codes for Construction Site Object Recognition
Topic: Math
Published: 9/1/2002
Authors: David E. Gilsinn, Geraldine S Cheok, Dianne M O'Leary
Abstract: This paper discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADARoptics. The first part of this paper describes the experimental data collection of several bar code images along w ...
