1. A Hybrid CPU-GPU Approach to Fourier-Based Image Stitching of Optical Microscopy Images
Topic: Scientific Computing
Published: 3/3/2013
Authors: Walid Keyrouz, Timothy J Blattner, Bertrand Clement Stivalet, Joe Chalfoun, Mary C Brady, Shujia Zhou
Abstract: We present a hybrid CPU-GPU approach for the Fourier-based stitching of optical microscopy images. This system achieves sub-minute stitching rates with large grids; it stitches a grid of 59x42 tiles in 26 seconds on a two-CPU (8 physical cores) & two ...

2. A Hybrid CPU-GPU System for Fourier-Based Stitching of Optical Microscopy Images
Topic: Scientific Computing
Published: 3/15/2013
Authors: Walid Keyrouz, Bertrand Clement Stivalet, Timothy J Blattner, Shujia Zhou, Joe Chalfoun, Mary C Brady
Abstract: We present a high performance hybrid CPU-GPU implementation that accelerates the Fourier-based stitching of 2D optical microscopy images to less than 1-minute (end-to-end execution times). This implementation takes advantage of coarse-grained parall ...

3. A Semantic Framework for Modeling and Simulation of Cyber-physical Systems
Topic: Scientific Computing
Published: 12/30/2014
Authors: Parastou Delgoshaei, Mark Austin, Amanda J Pertzborn
Abstract: This paper describes a new semantic platform infrastructure for model-based systems engineering, requirements traceability, and system simulation and assessment of cyberphysical systems (CPSs). When fully developed this environment will support t ...

4. An Evaluation of Local Shape Descriptors for 3D Shape Retrieval
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7812
Topic: Scientific Computing
Published: 3/8/2012
Author: Sarah Y. Tang
Abstract: As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. Most prominently, shape descriptors are used to describe the geometric and topological properties of objects and compared to determine t ...

5. Analysis for Dynamic Metrology
Topic: Scientific Computing
Published: 1/30/2014
Authors: Andrew M Dienstfrey, Paul D Hale
Abstract: Diverse measurement contexts require estimates of time varying quantities. Ideally the measurement device responds to signal variations significantly more rapidly than the modulation of the signal itself. If so, then well-developed techniques may b ...

6. Artificial Intelligence Tools for Failure Event Data Management and Probability Risk Analysis for Failure Prevention
Topic: Scientific Computing
Published: 10/25/2009
Authors: Jeffrey T Fong, Pedro Vincente Marcal
Abstract: Over the last thirty years, much research has been done on the development of failure event databases and fatigue modeling of crack growth in pressure vessels and piping. According to a USNRC report (NUREG/CR6674, 2000), results of a fatigue crack g ...

7. Conformance of Image Features to Classifier Assumptions
Topic: Scientific Computing
Published: 7/27/2012
Authors: Julien M. Amelot, Peter Bajcsy, Mary C Brady
Abstract: Cell measurements are derived frequently from the results of pixel classification and contiguous region segmentation of microscopy images. Image segmentation is accomplished by classifying image pixels based on high dimensional image features com ...

8. Detection and characterization of nonspecific, sparsely-populated binding modes for conformational selection in the early stages of complexation
Topic: Scientific Computing
Published: 3/18/2015
Authors: Antonio Cardone, Aaron Bornstein, Harish C. Pant, Mary C Brady, Ram D Sriram, Sergio Hassan
Abstract: A method is proposed to study protein-ligand binding in a system governed by specific and non-specific interactions. Strong associations lead to narrow conformational distributions in the proteins configuration space; weak and ultra-weak associations ...

9. Mathematical and Computational Sciences Division Summary of Activities for Fiscal Year 2009
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7671
Topic: Scientific Computing
Published: 2/25/2010
Author: Ronald F Boisvert
Abstract: This report summarizes the technical work of the Mathematical and Computational Sciences Division (MCSD) of NIST s Information Technology Laboratory. Part I (Overview) provides a high-level overview of the Division s activities, including highlight ...

10. Modeling of the Temperature Field in the Chip and in the Tool in High-speed Machining of a Carbon Steel: Effect of Pearlite to Austenite Phase Transition in AISI 1075
Topic: Scientific Computing
Published: 4/7/2010
Authors: Timothy J Burns, Steven P Mates, Richard L. Rhorer, Eric Paul Whitenton, Debasis Basak, Russell Hugh McFadden
Abstract: A one-dimensional transient finite-difference model for the temperature distribution in orthogonal metal cutting, which was originally developed by Boothroyd, and then improved upon by Tlusty, is used to calculate the temperature field in the chip an ...
