1. An Algorithm for Identifying Optimal Spreaders in a Random Walk Model of Network Communication
Series: Journal of Research (NIST JRES)
Topic: Modeling
Published: 5/10/2016
Author: Fern Y Hunt
Abstract: In a model of network communication based on a random walk in an undirected graph, what subset of nodes (subject to constraints on its size), enable the fastest spread of information? The dynamics of spread is described by a process dual to the movem ...

2. Shape Retrieval of Non-Rigid 3D Human Models
Topic: Modeling
Published: 4/26/2016
Authors: Afzal A Godil, David Pickup
Abstract: 3D models of humans are commonly used within computer graphics and vision, and so the ability to distinguish between body shapes is an important shape retrieval problem. We extend our recent paper which provided a benchmark for testing non-rigid ...

3. A set-theoretic approach to analyzing timing uncertainty within cyber-physical systems
Topic: Modeling
Published: 2/26/2016
Author: Dhananjay Anand
Abstract: Clocks are deeply integrated into practically every cyber-physical system either explicitly as provenance for time-triggered actions, or implicitly in cases where cyber components operate in lock step with physical dynamics. Recognizing the criti ...

4. Percolation phase diagrams for multi-phase models built on the overlapping sphere model
Topic: Modeling
Published: 9/16/2015
Author: Edward Joseph Garboczi
Abstract: The overlapping sphere (OS) model gives a two-phase microstructure (matrix plus inclusions) that is useful for testing out composite material ideas and other applications, as well as serving as a paradigm of continuum percolation and phase transition ...

5. Methodology and Calculator for High Precision Regression Fits of Pyranometer Angular Responsivities and the Associated Uncertainties
Topic: Modeling
Published: 6/23/2015
Author: Matthew T Boyd
Abstract: An easy to implement method for accurately utilizing pyranometer incidence angle dependent calibration factors, or responsivities (uV/W/m2), along with the associated uncertainties has been developed. This method uses algorithms for creating single p ...

6. The Decoupled Potential Integral Equation for Time-Harmonic Electromagnetic Scattering
Topic: Modeling
Published: 5/28/2015
Authors: Felipe Vico, Leslie Greengard, Miguel Ferrando, Zydrunas Gimbutas
Abstract: We present a new formulation for the problem of electromagnetic scattering from perfect electric conductors. While our representation for the electric and magnetic fields is based on the standard vector and scalar potentials A, {phi} in the Lorenz ga ...

7. Design and modeling of an ultra-compact 2x2 nanomechanical plasmonic switch
Topic: Modeling
Published: 5/4/2015
Author: Vladimir A Aksyuk
Abstract: A 2x2 Mach-Zehnder optical switch design with a footprint of 0.5 um x 2.5 um using nanomechanical gap plasmon phase modulators [1] is presented. The extremely small footprint and modest optical loss are enabled by the strong phase modulation of gap p ...

8. A comparison of 3D shape retrieval methods based on a large-scale benchmark supporting multimodal queries
Topic: Modeling
Published: 3/27/2015
Author: Afzal A Godil
Abstract: Large-scale 3D shape retrieval has become an important research direction in content-based 3D shape retrieval. To promote this research area, two Shape Retrieval Contest (SHREC) tracks on large scale comprehensive and sketch-based 3D model retrieva ...

9. A Decision Guidance Framework for Sustainability Performance Analysis of Manufacturing Processes
Topic: Modeling
Published: 1/10/2015
Authors: Duck Bong Kim, Seungjun Shin, Guodong Shao, Alexander Brodsky
Abstract: Life-Cycle Assessment (LCA) methods are widely used to assess the sustainability of manufacturing processes. Although it has several advantages such as systematic estimation and efficiency, it has significant limitations due to lack of functionality ...

10. Particle-based simulation of nanoscale systems and materials
Topic: Modeling
Published: 1/1/2015
Authors: Alexander Y Smolyanitsky, Vinod K Tewary
Abstract: This book chapter is focused on the introduction of molecular dynamics (MD) and molecular statics (MS), as well as some of their uses for studying the thermomechanical and (indirectly) electronic properties at the nanoscale. We first introduce th ...
