11. Contact function, uniform-thickness shell volume, and convexity measure for 3D star-shaped random particles
Topic: Software
Published: 3/15/2013
Authors: Edward Joseph Garboczi, Jeffrey W Bullard
Abstract: Using a spherical harmonic series, the three-dimensional shape of star-shaped particles can be represented mathematically as readily as can a sphere, cube, or ellipsoid. In principle, any particle parameter, such as volume, surface area, moment of in ...

12. Fast Sequential Importance Sampling to Estimate the Graph Reliability Polynomial
Topic: Software
Published: 11/8/2012
Authors: David G. Harris, Francis Sullivan, Isabel M Beichl
Abstract: The reliability polynomial of a graph measures the number of its connected subgraphs of various sizes. Algortihms based on sequential importance sampling (SIS) have been proposed to estimate a graph's reliahbility polynomial. We develop an improved ...

14. Fitting Weighted Total Least-Squares Planes and Parallel Planes to Support Tolerancing Standards
Topic: Software
Published: 10/19/2012
Authors: Craig M Shakarji, Vijay Srinivasan
Abstract: We present elegant algorithms for fitting a plane, two parallel planes (corresponding to a slot or a slab) or many parallel planes in a total (orthogonal) least-squares sense to coordinate data that is weighted. Each of these problems is reduced to a ...

15. An evaluation of local shape descriptors for 3D shape retrieval
Topic: Software
Published: 9/26/2012
Authors: Afzal A Godil, Sarah Y. Tang
Abstract: As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. A common approach is to calculate a shape descriptor for each object, which can then be compared to determine two objects‰ similarity. H ...

16. Review: Biological Imaging Software Tools
Topic: Software
Published: 8/29/2012
Authors: Anne L Plant, Kevin Eliceiri, Anne Carpenter
Abstract: Few technologies are more widespread in modern biological laboratories than imaging by microscopy. Advancements in optical technologies and instrumentation over the past twenty years have led to massive improvements in the resolution, specificity, d ...

17. A New Convexity Measurement for 3D Meshes
Topic: Software
Published: 6/16/2012
Authors: Afzal A Godil, Zhouhui Lian
Abstract: This paper presents a novel convexity measurement for 3D meshes. The new convexity measure is calculated by minimizing the ratio of the summed area of valid regions in a mesh‰s six views, which are projected on faces of the bounding box whose edg ...

18. Isolating Failure-Inducing Combinations in Combinatorial Testing using Test Augmentation and Classification
Topic: Software
Published: 4/21/2012
Authors: Kiran Shakya, Tao Xie, Nuo Li, Yu Lei, Raghu N Kacker, David R Kuhn
Abstract: Combinatorial Testing (CT) is a systematic way of sampling input parameters of the software under test (SUT). A t-way combinatorial test set can exercise all behaviors of the SUT caused by interactions between t input parameters or less. Although com ...

19. OOF3D: An Image-Based Finite Element Solver for Materials Science
Topic: Software
Published: 3/28/2012
Authors: Valerie R. Coffman, Andrew Charles edmu Reid, Stephen A Langer, Gunay Dogan
Abstract: Recent advances in experimental techniques (micro CT scans, automated serial sectioning, electron back-scatter diffraction, synchrotron radiation x-rays) have made it possible to characterize the full, three dimensional structure of real materials. S ...

20. Salient Local 3D Features for 3D Shape Retrieval
Topic: Software
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 ...
