41. Modeling electromigration using the peridynamics approach
Topic: Modeling
Published: 8/28/2011
Authors: David Thomas Read, Walter Gerstle, Vinod K Tewary
Abstract: This chapter presents a summary of the information and reasoning needed to justify learning about peridynamics for the purpose of analyzing electromigration and provides guidance for the development of a complete peridynamics analysis. The additions ...

42. On Parameter Differentiation for Integral Representations of Associated Legendre Functions
Topic: Modeling
Published: 5/24/2011
Author: Howard S Cohl
Abstract: For integral representations of associated Legendre functions in terms of modified Bessel functions, we establish justification for differentiation under the integral sign with respect to parameters. With this justification, derivatives for associate ...

43. 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 ...

44. Stability Analysis of Several Non-dilute Multiple Solute Transport Equations
Topic: Modeling
Published: 1/4/2011
Author: James D. Benson
Abstract: Recently a new solute and solvent transmembrane cellular transport model accounting for non-dilute solute concentrations was introduced. This model depends on a second or third order polynomial expansion in mole fraction of Gibbs energy for solutes a ...

Topic: Modeling
Published: 12/20/2010
Authors: Zhouhui Lian, Afzal A Godil
Abstract: Matching non-rigid shapes is a challenging research field in content-based 3D object retrieval. In this paper, we present an image-based method to effectively address this problem. Multidimensional Scaling (MDS) and Principal Component Analysis ( ...

46. Derivation of Isosceles Trapezoidal Distribution
Topic: Modeling
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 ...

47. Predicting Microstructure Development During Casting of Drug Eluting Coatings
Topic: Modeling
Published: 9/19/2010
Authors: David M. Saylor, Jonathan E Guyer, Daniel Wheeler, James A Warren
Abstract: We have devised a novel diffuse interface formulation to model the development of chem- ical and physical inhomogeneities, i.e. microstructure, during the process of casting drug eluting coatings. These inhomogeneities, which depend on the ...

48. A Flexible and Efficient Numerical Framework for Image Segmentation by Energy Minimization
Topic: Modeling
Published: 8/22/2010
Author: Gunay Dogan
Abstract: A widely used approach to image segmentation is to define corresponding segmentation energies and to compute shapes that are minimizers of these energies. In this work, we introduce a flexible and efficient numerical framework for minimization of suc ...

49. Spectral Based Methods That Streamline the Search for Failure Scenarios in Large-Scale Distributed Systems
Topic: Modeling
Published: 7/22/2010
Authors: Fern Y Hunt, Christopher E Dabrowski, Katherine Morrison
Abstract: We report our work on the development of analytical and numerical methods that enable the detection of failure scenarios in distributed grid computing, cloud computing and other large scale systems.

50. A Risk-Uncertainty Formula Accounting for Uncertainties of Failure Probability and Consequence in a Nuclear Powerplant
Topic: Modeling
Published: 7/20/2010
Authors: Jeffrey T Fong, Stephen R Gosselin, Pedro Vincente Marcal, James J Filliben, Nathanael A Heckert, Robert E Chapman
Abstract: This paper is a continuation of a recent ASME Conference paper entitled "Design of a Python-Based Plug-in for Bench-marking Probabilistic Fracture Mechanics Computer Codes with Failure Event Data" (PVP2009-77974). In that paper, which was co-authore ...
