41. Eigenfunction expansions for a fundamental solution of Laplace's equation on R^u3^ in parabolic and elliptic cylinder coordinates
Topic: Modeling
Published: 8/14/2012
Authors: Howard S Cohl, Hans Volkmer
Abstract: A fundamental solution of Laplace's equation in three dimensions is expanded in harmonic functions that are separated in parabolic or elliptic cylinder coordinates. There are two expansions in each case which reduce to expansions of the Bessel funct ...

42. 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 ...

43. The Date-Time Vocabulary
Topic: Modeling
Published: 7/28/2012
Authors: Mark H Linehan, Edward J Barkmeyer, Stan Hendryx
Abstract: The Date-Time Vocabulary is a new OMG specification that models continuous time, discrete time, the relationship of events and situations to time, language tense and aspect, time indexicals, timetables, and schedules. It offers a "business vocabulary ...

44. Conformance of Image Features to Classifier Assumptions
Topic: Modeling
Published: 7/27/2012
Authors: Julien Marc Amelot, Peter Bajcsy, Mary C Brady
Abstract: Cell measurements are derived frequently from the results of pixel classification and contiguous region segmentation of microscopy images. Image segmentation is accomplished by classifying image pixels based on high dimensional image features com ...

45. Evaluation of 3D Interest Point Detection Techniques via Human-generated Ground Truth
Topic: Modeling
Published: 6/29/2012
Authors: Afzal A Godil, Helin Dutagaci
Abstract: In this paper, we present an evaluation strategy based on human-generated ground truth to measure the performance of 3D interest point detection techniques. We provide quantitative evaluation measures that relate automatically detected interest point ...

46. Predicting Global Failure Regimes in Complex Information Systems
Topic: Modeling
Published: 6/19/2012
Authors: Christopher E Dabrowski, James J Filliben, Kevin L Mills
Abstract: Over the past five years, we investigated methods to characterize global behavior in large distributed systems and applied those methods to predict effects from deploying alternate distributed control algorithms. The methods we used assess global beh ...

47. A New Convexity Measurement for 3D Meshes
Topic: Modeling
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 ...

48. Towards a Metric for Communication Network Vulnerability to Attacks: A Game Theoretic Approach
Topic: Modeling
Published: 5/25/2012
Authors: Assane Gueye, Vladimir V Marbukh, Jean C Walrand
Abstract: In this paper, we propose a quantification of the vulnerability of a communication network when links are subject to failures due to the actions of a strategic adversary. We model the adversarial nature of the problem as a 2-player game between an at ...

49. Micromagnetic investigation of periodic cross-tie/vortex wall geometry
Topic: Modeling
Published: 5/18/2012
Author: Michael J Donahue
Abstract: A systematic series of micromagnetic simulations on periodic cross-tie/vortex wall structures in an ideal soft film at various width, thickness, and period lengths is performed. For each width and thickness a natural period length is found which has ...

50. SHREC‰12 Track: Generic 3D Shape Retrieval
Topic: Modeling
Published: 5/13/2012
Authors: Bo Li, Afzal A Godil
Abstract: Generic 3D shape retrieval is a fundamental research area in the field of content-based 3D model retrieval. The aim of this track is to measure and compare the performance of generic 3D shape retrieval methods implemented by different participant ...
