Progress in Materials Data Availability and Application: A Review

December 28, 2021
Author(s)
Chandler A. Becker, James A. Warren
Materials researchers are generating data in ever-increasing volumes, and this data is, in turn, fueling the discovery and design of new materials. These changes are enabled by advances in data capture via laboratory information management systems (LIMS)

Interface-Anisotropy Induced Asymmetry of Intermixing in Bilayers

October 12, 2021
Author(s)
P Sule, M. Menyhard, L Kotis, J Labar, William F. Egelhoff Jr.
The ion-sputtering induced intermixing is studied by molecular dynamics (MD) simulations and by Auger electron spectroscopy depth profiling (AES-SP) analysis in PT/Ti/Si (Pt/Ti) and Ta/Ti/Pt/Si(Ti/Pt) bilayers. Experimental evidence is found for the

JPEG 2000 CODEC Certification Guidance for 1000 ppi Fingerprint Friction Ridge Imagery

May 5, 2021
Author(s)
Shahram Orandi, John M. Libert, John Grantham, Michael Garris, Frederick R. Byers
The document describes the procedure by which applications of JPEG 2000 CODECs will be evaluated with respect to conformance to the NIST guidance for compression of 1000 ppi friction ridge images as detailed in NIST Special Publication 500-289 [NIST3]. The

Consistency in Monte Carlo Uncertainty Analyses

July 14, 2020
Author(s)
Benjamin F. Jamroz, Dylan F. Williams
The Monte Carlo method is an established tool that is often used to evaluate the uncertainty of measurements. For computationally challenging problems, Monte Carlo uncertainty-analyses are typically distributed across multiple processes on a multi-node

Nestor: A Tool for Natural Language Annotation of Short Texts

November 1, 2019
Author(s)
Michael Brundage, Rachael Sexton
Nestor is a software tool that annotates natural language CSV (comma-separated variable) files, with a UTF-8 encoding, using a process called tagging [1]. The outputted annotated datasets (as either a CSV or .h5 file) can be used for different analysis

Influence of Ion Solvation on the Properties of Electrolyte Solutions

April 3, 2018
Author(s)
Marat Andreev, Juan J. DePablo, Alexandros Chremos, Jack F. Douglas
It is widely appreciated that the addition of salts to water leads to significant changes in the thermodynamic and dynamic properties of these aqueous solutions, which have great significance in biology and manufacturing applications. However, no

Fast optimization algorithms and the cosmological constant

November 1, 2017
Author(s)
Stephen P. Jordan, Ning Bao, Brad Lackey, Raphael Bousso
Denef and Douglas have observed that in certain landscape models the problem of finding small values of the cosmological constant is a large instance of an NP-hard problem. The number of elementary operations (quantum gates) needed to solve this problem by

Approaches for Characterizing Nonlinear Mixtures in Hyperspectral Imagery

June 21, 2017
Author(s)
Robert S. Rand, Ronald G. Resmini, David W. Allen
This study considers a physics-based and a kernel-based approach for characterizing pixels in a scene that may be linear (areal mixed) or nonlinear (intimately mixed). The physics-based method is based on earlier studies that indicate nonlinear mixtures in

Simulations of Microstructural Evolution: Anisotropic Growth and Coarsening

February 19, 2017
Author(s)
A R. Roosen, W Carter
Two-dimensional calculations of anisotropic growth and coarsening are illustrated. This model is intended to simulate the development of microstructure in materials like Silicon Nitride. The model is comprised of an ensemble of polygonal particles with

Wind Effects on Flame Spread and Ember Spotting Near a Structure

February 6, 2017
Author(s)
Kathryn M. Butler, Erik L. Johnsson, Marco G. Fernandez, Mariusz Zarzecki, Glenn P. Forney, Eric Auth
In wildland-urban interface (WUI) fires, combustible materials pose a potential threat to contiguous or nearby structures. Flame spread and firebrand spotting have been studied in a series of field experiments involving fences and mulch beds under a

Optimized Air-to-Refrigerant Heat Exchanger With Low-GWP Refrigerants

August 20, 2016
Author(s)
Piotr A. Domanski, Hong Hyun Cho
This paper presents an analytical evaluation of the performance of low-GWP refrigerants in a finned-tube evaporator used for residential cooling applications. The study employed an evolutionary-computation optimization module to examine the effect of a

XAFS Data Interchange: A single spectrum XAFS data file format

June 9, 2016
Author(s)
Bruce D. Ravel, M. Newville
We propose a standard data format for the interchange of XAFS data. The XAFS Data Interchange (XDI) standard is meant to encapsulate a single spectrum of XAFS along with relevant metadata. XDI is a text-based format with a simple syntax which clearly

Navigation Performance Evaluation for Automated Guided Vehicles

May 12, 2015
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Geraldine S. Cheok
Automatic guided vehicles (AGVs), an industrial form of mobile robot, typically navigate using a central computer commanding AGV movement on predefined paths. Although, how well they follow these paths is less defined in research articles and their

SHREC'15: Range Scans based 3D Shape Retrieval

May 3, 2015
Author(s)
Afzal A. Godil
The objective of the SHREC'15 Range Scans based 3D Shape Retrieval track is to evaluate algorithms that match range scans of real objects to complete 3D mesh models in a target dataset. The task is to retrieve a rank list of complete 3D models that are of

A Semantic Framework for Modeling and Simulation of Cyber-physical Systems

December 30, 2014
Author(s)
Parastoo Delgoshaei, Mark Austin, Amanda Pertzborn
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 the

Performance evaluation of fingerprint open-set identification algorithms

September 22, 2014
Author(s)
Elham Tabassi, Craig I. Watson, Gregory P. Fiumara
We report performance of one-to-many fingerprint identification algorithms using one, two, four, eight or ten fingers for recognition. Performance is quantified in terms of recognition accuracy (false positive and false negative identification rate)

An Optimization Approach for Semantic-based XML Schema Matching

May 16, 2013
Author(s)
Jaewook Kim, Yun Peng, Nenad Ivezic, Jun H. Shin
We propose a novel solution for semantic-based XML schema matching, taking a mathematical programming approach. This method identifies the globally optimal solution for the problem of matching leaf nodes between two XML schema trees by reducing the tree-to
