111. SHREC‰13 Track: Large Scale Sketch-Based 3D Shape Retrieval
Topic: Modeling
Published: 6/6/2013
Authors: Afzal A Godil, Bo Li , Yijuan Lu, Tobias Schreck
Abstract: Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. The aim of this track is to measure and compare the performance of sketch-based 3D shape retrieval methods based on a large scale hand-draw ...

112. Salient Local 3D Features for 3D Shape Retrieval
Topic: Modeling
Published: 4/7/2011
Authors: Afzal A Godil, Asim Wagan
Abstract: In this paper we describe a new formulation for the 3D salient local features based on the voxel grid inspired by the Scale Invariant Feature Transform (SIFT). We use it to identify the salient keypoints (invariant points) on a 3D voxelized model and ...

113. Sensitivities and Variances for Fitted Parameters of Spheres
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7616
Topic: Modeling
Published: 7/1/2009
Authors: Christoph Johann Witzgall, Marek Franaszek
Abstract: Experimental data have been gathered by applying 3D imaging systems, such as LIDAR/LADAR instruments, to spherical objects. This report provides a compilation of the statistical and analytical procedures to be used for an evaluation, to be reported ...

114. Separation of variables in an asymmetric cyclidic coordinate system
Topic: Modeling
Published: 6/27/2013
Authors: Howard S Cohl, Hans Volkmer
Abstract: A global analysis is presented of solutions for Laplace's equation on three-dimensional Euclidean space in one of the most general orthogonal asymmetric confocal cyclidic coordinate system which admits solutions through separation of variables. ...

115. Shape Calculus for Shape Energies in Image Processing
Topic: Modeling
Published: 7/22/2013
Authors: Gunay Dogan, Ricardo H. Nochetto
Abstract: Many image processing problems are naturally expressed as energy minimization or shape optimization problems, in which the free variable is a shape, such as a curve in 2d or a surface in 3d. Examples are image segmentation, multiview stereo reconstru ...

116. Single Diode Equivalent Circuit Models
Topic: Modeling
Published: 9/12/2013
Authors: Matthew T Boyd, Clifford Hansen

117. 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.

118. Spectrum Simulation in DTSA-II
Report Number: 832430
Topic: Modeling
Published: 10/1/2009
Author: Nicholas W m Ritchie
Abstract: Spectrum simulation is a useful practical and pedagogical tool. Particularly with complex samples or trace constituents, a simulation can help to understand the limits of the technique and how to optimize the tools for the optimal measurement. DTSA- ...

119. 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 ...

120. Stochastic Regression Modeling of Chemical Spectra
Topic: Modeling
Published: Date unknown
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 ...
