31. Attractors, Chain Transitive Sets and Invariant Measures
Topic: Math
Published: 9/15/2000
Author: Fern Y Hunt
Abstract: This paper discusses an easy to implement procedure for approximating the long time behavior of iterates of maps. Applications include to finding the roots of a complex polynomial and approximating attractors. The method uses the theory of Markov ch ...

33. Bayesian Alternative to the Guide's Use of the Welch-Satterthwaite Formula
Topic: Math
Published: 1/3/2006
Author: Raghu N Kacker
Abstract: The Guide to the Expression of Uncertainty in Measurement suggests that to account for the statistical uncertainty in a combined standard uncertainty that arises when one or more of its components are evaluated from a limited number of independent no ...

34. Bayesian Posterior Predictive p-value of Statistical Consistency in Interlaboratory Evaluations
Topic: Math
Published: 9/17/2008
Authors: Raghu N Kacker, Alistair Forbes, Ruediger Kessel, K D Sommer
Abstract: Results from an interlaboratory evaluation are said to be statistically consistent if they fit a normal (Gaussian) consistency model which postulates that the results have the same unknown expected value and stated variances and covariances. We prop ...

36. 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 ...

37. Bifurcations, Center Manifolds, and Periodic Solutions
Topic: Math
Published: 1/15/2009
Author: David E. Gilsinn
Abstract: Nonlinear time delay differential equations are well known to have arisen in models in physiology, biology, and population dynamics. They have also arisen in models of metal cutting processes. Machine tool chatter, from a process called regenerative ...

38. 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 ...

39. 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 ...
