61. Feature-preserved 3D Canonical Form
Topic: Modeling
Published: 7/28/2012
Authors: Afzal A Godil, Zhouhui Lian
Abstract: Abstract Measuring the dissimilarity between non-rigid objects is a challenging problem in 3D shape retrieval. One potential solution is to construct the models‰ 3D canonical forms (i.e., isometry-invariant representations in 3D Euclidean domain) on ...

62. First Variation of the General Curvature-dependent Surface Energy
Topic: Modeling
Published: 1/1/2012
Authors: Gunay Dogan, Ricardo H. Nochetto
Abstract: We consider general weighted surface energies, where the energies have the form of weighted integrals over a closed surface and the weight depends on the normal and the mean curvature of the surface. Energies of this form have applications in many ar ...

63. Fourier Expansions for a Logarithmic Fundamental Solution of the Polyharmonic Equation
Topic: Modeling
Published: 9/28/2012
Author: Howard S Cohl
Abstract: In even-dimensional Euclidean space for integer powers of the Laplacian greater than or equal to the dimension divided by two, a fundamental solution for the polyharmonic equation has logarithmic behavior. We give two approaches for developing a Fou ...

64. Fourier and Gegenbauer expansions for a fundamental solution of the Laplacian in the hyperboloid model of hyperbolic geometry
Topic: Modeling
Published: 3/23/2012
Authors: Howard S Cohl, Ernie G. Kalnins
Abstract: Due to the isotropy of d-dimensional hyperbolic space, there exists a spherically symmetric fundamental solution for its corresponding Laplace-Beltrami operator. The R-radius hyperboloid model of hyperbolic geometry with R > 0 represents a Riemannian ...

65. Fourier, Gegenbauer and Jacobi expansions for a power-law fundamental solution of the polyharmonic equation and polyspherical addition theorems
Topic: Modeling
Published: 6/5/2013
Author: Howard S Cohl
Abstract: We develop complex Jacobi, Gegenbauer and Chebyshev polynomial expansions for the kernels associated with power-law fundamental solutions of the polyharmonic equation on d-dimensional Euclidean space. From these series representations we derive Fouri ...

66. From atoms to steps: the microscopic origins of crystal growth.
Topic: Modeling
Published: 7/1/2014
Authors: Paul N. Patrone, T L Einstein, Dionisios Margetis

67. Front Matter for Special Issue of NIST Journal of Research in honor of Christoph Witzgall
Series: Journal of Research (NIST JRES)
Topic: Modeling
Published: 3/31/2006
Authors: David E. Gilsinn, Ronald F Boisvert
Abstract: This front matter for a special issue of the NIST Journal of Research contains a photograph and biography of Christoph Witzgall. It also contains a thank you paragraph by Christoph Witzgall for a symposium held in his honor. Many of the papers in thi ...

68. Fundamental Solution of Laplace's Equation in Hyperspherical Geometry
Topic: Modeling
Published: 11/29/2011
Author: Howard S Cohl
Abstract: Due to the isotropy of $d$-dimensional hyperspherical space, one expects there to exist a spherically symmetric fundamental solution for its corresponding Laplace-Beltrami operator. The $R$-radius hypersphere ${\mathbf S}_R^d$ with $R>0$, represents ...

69. Gauging the Repeatability of 3D Imaging Systems by Sphere Fitting
Topic: Modeling
Published: 9/30/2009
Authors: Marek Franaszek, Geraldine S Cheok, Kamel Shawki Saidi
Abstract: Multiple scans of the same object acquired with 3D imaging system (e.g., laser scanner) in the same experimental conditions could provide valuable information about the instrument s performance (e.g., stability, existence of bias, measurement error). ...

70. 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 ...
