1. Expansions for a fundamental solution of Laplace's equation on R^u3^ in 5-cyclidic harmonics
Topic: Modeling
Published: 10/14/2014
Authors: Howard S Cohl, Hans Volkmer
Abstract: We derive eigenfunction expansions for a fundamental solution of Laplace's equation in three-dimensional Euclidean space in 5-cyclidic coordinates. There are three such expansions in terms of internal and external 5-cyclidic harmonics of first, seco ...

2. Stochastic Regression Modeling of Chemical Spectra
Topic: Modeling
Published: 8/14/2014
Authors: Anthony J Kearsley, William E Wallace III, Yutheeka Gadhyan
Abstract: A stochastic regression method has been developed that decomposes chemical spectra into separate contributions from signal and from noise. The numerical results of regressing in this way on sample spectra are presented. The results suggest that this ...

4. 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 ...

5. Distributed Deployment Algorithms for Improved Coverage in a Network of Wireless Mobile Sensors
Topic: Modeling
Published: 2/1/2014
Authors: Kamran Sayrafian, Vladimir V Marbukh, Hamid Mahboubi, Kaveh Moezzi, Amir Aghdam
Abstract: In this paper, sensor deployment strategies are developed for effective coverage in wireless sensor networks. In the proposed algorithms, the sensors find coverage holes within the corresponding Voronoi polygons, and then move in a proper directi ...

6. Generalization and specializations of generating functions for Jacobi, Gegenbauer, Chebyshev and Legendre polynomials with definite integrals
Topic: Modeling
Published: 1/15/2014
Authors: Howard S Cohl, Connor M. MacKenzie
Abstract: In this paper we generalize and specialize generating functions for classical orthogonal polynomials, namely Jacobi, Gegenbauer, Chebyshev and Legendre polynomials. We derive a generalization of the generating function for Gegenbauer polynomials thro ...

7. Feature Measures for the Segmentation of Neuronal Membrane using Machine Learning Algorithm
Topic: Modeling
Published: 1/6/2014
Authors: Afzal A Godil, Saadia S. Iftikhar
Abstract: In this paper, we present a Support Vector Machine (SVM) based pixel classifier for a semi-automated segmentation algorithm to detect neuronal membrane structures in stacks of electron microscopy images of brain tissue samples. This algorithm uses ...

8. A comparison of methods for sketch-based 3D shape retrieval
Topic: Modeling
Published: 12/13/2013
Author: Afzal A Godil
Abstract: Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) tracks on this topic have been organized by us in 2012 and 2013 based on ...

9. PROCESS DESCRIPTION AND ANALYTICS FORMALISM FOR DECISION GUIDANCE IN SUSTAINABLE MANUFACTURING
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7961
Topic: Modeling
Published: 11/20/2013
Authors: Alexander Brodsky, Guodong Shao, Frank H Riddick
Abstract: This paper introduces NIST‰s Sustainable Process Analytics Formalism (SPAF) to facilitate the use of simulation and optimization technologies for decision support in sustainable manufacturing. SPAF allows formal modeling of modular, extensible, and r ...

10. Successive Frequency Domain Minimization for Time Delay Estimation
Topic: Modeling
Published: 11/12/2013
Authors: Ismet Sahin, Marwan A Simaan, Anthony J Kearsley
Abstract: Estimating time delays for signal alignment is important for many applications. This paper extends a successful frequency domain cost function minimization algorithm capable of estimating time delays to within a fraction of sampling periods. Since ...
