11. A study of shear banding in polymer solutions
Topic: Modeling
Published: 6/4/2014
Authors: Michael E Cromer, Glenn Fredrickson, Gary Leal
Abstract: In a recent letter (Cromer et al. Phys. Fluids 2013) we showed, for the first time, the existence of a steady shear-banded velocity profile for a polymer solution with an underlying monotonic constitutive curve. The driving mechanism is the coupling ...

12. An Optimization Approach to Multiple Sequence Alignment
Topic: Modeling
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 ...

13. Artificial Intelligence Tools for Failure Event Data Management and Probability Risk Analysis for Failure Prevention
Topic: Modeling
Published: 10/25/2009
Authors: Jeffrey T Fong, Pedro Vincente Marcal
Abstract: Over the last thirty years, much research has been done on the development of failure event databases and fatigue modeling of crack growth in pressure vessels and piping. According to a USNRC report (NUREG/CR6674, 2000), results of a fatigue crack g ...

14. Assessing microscale heterogeneity in batches of reference materials using microbeam XRF
Topic: Modeling
Published: 5/17/2011
Authors: John L Molloy, John R Sieber
Abstract: Principal component analysis (PCA), microbeam X-ray Fluorescence Spectrometry (µXRF), and Monte Carlo simulations are used to illustrate a methodology for assessing the sample microheterogeneity for large sets of materials. PCA is demonstrated to de ...

15. COMPARISON OF TWO DIMENSION-REDUCTION METHODS FOR NETWORK SIMULATION MODELS
Series: Journal of Research (NIST JRES)
Report Number: 116-5
Topic: Modeling
Published: 10/5/2011
Authors: Kevin L Mills, James J Filliben
Abstract: Experimenters characterize the behavior of simulation models for data communications networks by measuring multiple responses under selected parameter combinations. The resulting multivariate data may include redundant responses reflecting aspects of ...

16. Colored Noise and Regularization Parameter Selection for Waveform Metrology
Topic: Modeling
Published: 7/8/2014
Authors: Andrew M Dienstfrey, Paul D Hale
Abstract: We study six regularization parameter selection algorithms applied to deconvolution problems relevant for characterization of high-speed communication measurement systems. In particular we investigate the performance of these selectors in the presen ...

17. Conformance of Image Features to Classifier Assumptions
Topic: Modeling
Published: 7/27/2012
Authors: Julien Marc Amelot, Peter Bajcsy, Mary C Brady
Abstract: Cell measurements are derived frequently from the results of pixel classification and contiguous region segmentation of microscopy images. Image segmentation is accomplished by classifying image pixels based on high dimensional image features com ...

18. Constructing Sequence Alignments from a Markov Decision Model with Estimated Parameter Values
Topic: Modeling
Published: 1/1/2004
Authors: Fern Y Hunt, Anthony J Kearsley, Agnes (Abbie) O'Gallagher
Abstract: Current methods for aligning biological sequences are based on dynamic programming algorithms. If large numbers of sequences or a number of long ones are to be aligned the required computations are expensive in memory and CPU time. In an attempt to b ...

20. DATA ANALYTICS USING SIMULATION FOR SMART MANUFACTURING
Topic: Modeling
Published: 12/11/2014
Authors: Guodong Shao, Sanjay Jain, Seungjun Shin
Abstract: Manufacturing organizations are able to accumulate large amounts of plant floor production and environmental data due to advances in data collection, communications technology, and use of standards. The challenge has shifted from collecting a suffic ...
