11. A comparison of methods for sketch-based 3D shape retrieval
Topic: Modeling
Published: 12/13/2013
Author: Afzal A Godil
Abstract: Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) tracks on this topic have been organized by us in 2012 and 2013 based on ...

12. PROCESS DESCRIPTION AND ANALYTICS FORMALISM FOR DECISION GUIDANCE IN SUSTAINABLE MANUFACTURING
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7961
Topic: Modeling
Published: 11/20/2013
Authors: Alexander Brodsky, Guodong Shao, Frank H Riddick
Abstract: This paper introduces NIST‰s Sustainable Process Analytics Formalism (SPAF) to facilitate the use of simulation and optimization technologies for decision support in sustainable manufacturing. SPAF allows formal modeling of modular, extensible, and r ...

13. Successive Frequency Domain Minimization for Time Delay Estimation
Topic: Modeling
Published: 11/12/2013
Authors: Ismet Sahin, Marwan A Simaan, Anthony J Kearsley
Abstract: Estimating time delays for signal alignment is important for many applications. This paper extends a successful frequency domain cost function minimization algorithm capable of estimating time delays to within a fraction of sampling periods. Since ...

14. Combining Genetic Algorithms & Simulation to Search for Failure Scenarios in System Models
Topic: Modeling
Published: 10/28/2013
Authors: Kevin L Mills, Christopher E Dabrowski, James J Filliben, Sanford P Ressler
Abstract: Large infrastructures, such as clouds, can exhibit substantial outages, sometimes due to failure scenarios that were not considered during system design. We define a method that uses a genetic algorithm (GA) to search system simulations for parameter ...

16. Hybrid shape descriptor and meta similarity generation for non-rigid and partial 3D model retrieval
Topic: Modeling
Published: 7/26/2013
Author: Afzal A Godil
Abstract: Non-rigid and partial 3D model retrieval are two significant and challenging research directions in the field of 3D model retrieval. Little work has been done in proposing a hybrid shape descriptor that works for both retrieval scenarios, let alone ...

17. 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 ...

18. On the Delay and Data Rate Performance of Throughput-Efficient Multi-Channel Access Algorithms in Cognitive Radio Networks
Topic: Modeling
Published: 7/8/2013
Authors: Kamran Sayrafian, Luca Zappaterra, Hyeong-Ah Choi, Jari Iinatti
Abstract: Cognitive Radio Networks (CRNs) are designed to increase spectrum utilization by allowing unlicensed secondary users (SUs) to operate over existing wireless channels where primary users (PUs) have license to transmit. An SU searches for channels not ...

19. 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. ...

20. Quantifying Network Topology Robustness Under Budget Constraints
Topic: Modeling
Published: 6/24/2013
Authors: Assane Gueye, Aron Lazska
Abstract: To design robust network topologies that resist strategic attacks, one must first be able to quantify robustness. In a recent line of research, the theory of network blocking games has been used to derive robustness metrics for topologies. A netw ...
