41. 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 ...

42. 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 ...

43. 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 ...

44. SHREC‰12 Track: Sketch-Based 3D Shape Retrieval
Topic: Modeling
Published: 5/13/2012
Authors: Bo Li, Afzal A Godil
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 implemented by different parti ...

45. A diffuse-interface Model of Reactive Wetting with Intermetallic Formation
Topic: Modeling
Published: 5/1/2012
Authors: Walter Villaneuva, William J Boettinger, Geoffrey B McFadden, James A Warren
Abstract: A diffuse-interface model of reactive wetting with intermetallic formation is developed that incorporates fluid flow, phase change, and solute diffusion. The model is based on the total molar Gibbs energy of a ternary system with four phases. Numeric ...

46. Maximum Entropy and Time-Domain Kramers-Kronig Phase Retrieval Approaches are Functionally Equivalent for CARS Micro-Spectroscopy
Topic: Modeling
Published: 4/27/2012
Authors: Marcus T Cicerone, Khaled A. Aamer, Young Jong Lee, Eric Vartiainen
Abstract: Phase retrieval methods are used to recover Raman spectra from multiplex and broadband CARS signals. Two methods are in widespread use, one based on maximum entropy (MEM), and one based on a modified time-domain Kramers-Kronig (TDKK) method. He ...

47. LDPC Error Correction in the Context of Quantum Key Distribution
Topic: Modeling
Published: 4/23/2012
Author: Anastase Nakassis
Abstract: Secret keys can be established through the use of Quantum channels monitored through classical channels which can be thought of as being error free. Because many of the feasible implementation of the quantum channel are subject to erasures ‹often mas ...

48. OOF3D: An Image-Based Finite Element Solver for Materials Science
Topic: Modeling
Published: 3/28/2012
Authors: Valerie R. Coffman, Andrew C.E. Reid, Stephen 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 ...

49. 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 ...

50. Light a Single Candle: Studying Supernovae
Topic: Modeling
Published: 3/1/2012
Authors: Dianne M O'Leary, Bert W Rust
Abstract: At peak luminosity, Type Ia supernovae can be even brighter than their parent galaxies, and their light curves display a very uniform and regular behavior. This makes them excellent candidates for a role as standard candles in measuring the distance ...
