11. Stochastic Regression Modeling of Chemical Spectra
Topic: Modeling
Published: 8/14/2014
Authors: Anthony J Kearsley, William E Wallace III, Yutheeka Gadhyan
Abstract: A stochastic regression method has been developed that decomposes chemical spectra into separate contributions from signal and from noise. The numerical results of regressing in this way on sample spectra are presented. The results suggest that this ...

12. Colored Noise and Regularization Parameter Selection for Waveform Metrology
Topic: Modeling
Published: 7/8/2014
Authors: Andrew M Dienstfrey, Paul D Hale
Abstract: We study six regularization parameter selection algorithms applied to deconvolution problems relevant for characterization of high-speed communication measurement systems. In particular we investigate the performance of these selectors in the presen ...

13. From atoms to steps: the microscopic origins of crystal growth.
Topic: Modeling
Published: 7/1/2014
Authors: Paul N Patrone, T L Einstein, Dionisios Margetis

14. Elucidating the Effects of Adsorbent Flexibility on Fluid Adsorption Using Simple Models and Flat-Histogram Sampling Methods
Topic: Modeling
Published: 6/24/2014
Authors: Vincent K Shen, Daniel W Siderius
Abstract: Using flat-histogram Monte Carlo methods, we investigate the adsorptive behavior of the square-well fluid in two simple slit-pore- like models intended to capture fundamental characteristics of flexible adsorbent materials. The models require thermo ...

15. 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 ...

16. 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 ...

17. 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

18. 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 ...

19. 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 ...

20. 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 ...
