21. A study of shear banding in polymer solutions
Topic: Modeling
Published: 6/4/2014
Authors: Michael E Cromer, Glenn Fredrickson, Gary Leal
Abstract: In a recent letter (Cromer et al. Phys. Fluids 2013) we showed, for the first time, the existence of a steady shear-banded velocity profile for a polymer solution with an underlying monotonic constitutive curve. The driving mechanism is the coupling ...

22. Distributed Deployment Algorithms for Improved Coverage in a Network of Wireless Mobile Sensors
Topic: Modeling
Published: 2/1/2014
Authors: Kamran Sayrafian, Vladimir V Marbukh, Hamid Mahboubi, Kaveh Moezzi, Amir Aghdam
Abstract: In this paper, sensor deployment strategies are developed for effective coverage in wireless sensor networks. In the proposed algorithms, the sensors find coverage holes within the corresponding Voronoi polygons, and then move in a proper directi ...

23. Connection of Kinetic Monte Carlo Model for Surfaces to Step-Continuum Theory in 1+1 Dimensions
Topic: Modeling
Published: 1/1/2014
Authors: Paul N Patrone, Dionisios Margetis

24. 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 ...

25. 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 ...

26. 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 ...

27. SHREC‰13 Track: Large Scale Sketch-Based 3D Shape Retrieval
Topic: Modeling
Published: 6/6/2013
Authors: Afzal A Godil, Bo Li , Yijuan Lu, Tobias Schreck
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 based on a large scale hand-draw ...

28. Modeling Scanning Electron Microscope Measurements with Charging
Topic: Modeling
Published: 4/3/2013
Author: John S Villarrubia
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=912857

29. Contact function, uniform-thickness shell volume, and convexity measure for 3D star-shaped random particles
Topic: Modeling
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 ...

30. SysML extension for dynamical system simulation tools
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7888
Topic: Modeling
Published: 10/26/2012
Authors: Ion Matei, Conrad E Bock
Abstract: Computer-interpretable representations of system structure and behavior are at the center of designing today‰s complex systems. Engineers create and review such representations using graphical modeling languages that support specification, analys ...
