11. 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 ...

12. 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 ...

13. 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 ...

14. 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 ...

15. 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 ...

16. Predicted Energy Resolution of a Running-Sum Algorithm for Microcalorimeters
Topic: Modeling
Published: 12/1/2011
Authors: Bradley K Alpert, William Bertrand Doriese, Joseph Westbrook Fowler, Joel Nathan Ullom
Abstract: The energy resolution of a high-pulse-rate filtering algorithm recently introduced by Hui Tan et al., based on running sums of TES microcalorimeter output streams, is predicted from average pulse shape and noise autocovariance. We compare with empiri ...

17. Comparing VM-Placement Algorithms for On-Demand Clouds
Topic: Modeling
Published: 11/29/2011
Authors: Kevin L Mills, James J Filliben, Christopher E Dabrowski
Abstract: Much recent research has been devoted to investigating algorithms for allocating virtual machines (VMs) to physical machines (PMs) in infrastructure clouds. Many such algorithms address distinct problems, such as initial placement, consolidation, or ...

18. 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 ...

19. VM Leakage and Orphan Control in Open-Source Clouds
Topic: Modeling
Published: 11/29/2011
Authors: Christopher E Dabrowski, Kevin L Mills
Abstract: Computer systems often exhibit degraded performance due to resource leakage caused by erroneous programming or malicious attacks, and computers can even crash in extreme cases of resource exhaustion. The advent of cloud computing provides increased o ...

20. In Search of Enhanced Electrolyte Materials: A Case Study of Doubly Doped Ceria
Topic: Modeling
Published: 10/28/2011
Authors: Pratik Dholabhai, James B. Adams, Peter A. Crozier, Renu Sharma
Abstract: Various compositions of gadolinium-praseodymium doubly doped ceria (GPDC) have been studied to appreciate the effect of two co-dopants in enhancing the ionic conductivity. A Kinetic Lattice Monte Carlo (KLMC) model of vacancy diffusion in GPDC has be ...
