Data Resources for Thermophysical Properties of Metals and Alloys, Part 1: Structured Data Capture from the Archival Literature

January 7, 2017
Author(s)
Boris Wilthan, Erik A. Pfeif, Vladimir Diky, Robert D. Chirico, Ursula R. Kattner, Kenneth G. Kroenlein
In support of the continuous scientific and industrial need for accessible and high-quality thermophysical property data for metals and alloy systems, NIST/TRC is expanding its data archiving and critical evaluation activities to include this area. As part

Linear Time Vertex Partitioning on Massive Graphs

March 7, 2016
Author(s)
Peter M. Mell, Richard Harang, Assane Gueye
The problem of optimally removing a set of vertices from a graph to minimize the size of the largest resultant component is known to be NP-complete. Prior work has provided near optimal heuristics with a high time complexity that function on up to hundreds

Measuring Limits on the Ability of Colluding Countries to Partition the Internet

June 30, 2015
Author(s)
Peter M. Mell, Richard Harang, Assane Gueye
We show that the strength of Internet-based network interconnectivity of countries is increasing over time. We then evaluate bounds on the extent to which a group of colluding countries can disrupt this connectivity. We evaluate the degree to which a group

An Understanding of High Entropy Alloy from Phase Diagram Calculation

November 12, 2013
Author(s)
Fan Zhang, Chuan Zhang, Shuang-Lin Chen, J Zhu, Wei-Sheng Cao, Ursula R. Kattner
The concept of High Entropy Alloy (HEA) is understood from the point of view of phase diagram calculation. The role of entropy of mixing on the phase stability is discussed for both ideal and non-ideal solid solution phases. The relative stability of a

Asymptotic Behavior of a Strain Percolation Model for a Deforming Metal

March 1, 2003
Author(s)
Y Shim, Lyle E. Levine, R M. Thomson, D E. Kramer
In this paper, we present a recent advance in theoretical understanding of a deforming metal, using a strain percolation model which possibly explains spasmodic, fine slip line burst events occurring in the metal. The model addresses how the additional

Estimating Local Dimensionality

December 15, 1997
Author(s)
D L. Banks, R Olszewski
This paper suggests that one can use principal components analysis to assess the local dimensionality in a complex dataset. If this is large, then data mining is unlikely to be successful. If it is small, then various statistical techniques may be able to

Optimized Sparse Sampling Lattices

March 7, 2023
Author(s)
Peter Vouras, Mohamed Hany, Sudantha Perera, Carnot Nogueira, Rick Candell, Kate Remley
Sparse sampling approaches have been widely studied to achieve less complex measurement systems while maintaining detection performance. In this paper, we derive a new gradient implementation of an alternating projections algorithm that determines the

Wideband Synthetic Aperture Test Bed for Intelligent Reflecting Surfaces

March 7, 2023
Author(s)
Peter Vouras, Mohamed Hany, Sudantha Perera, Carnot Nogueira, Rick Candell, Kate Remley
This paper describes a spherical beamforming implementation for wideband synthetic aperture channel sounders that can be used to predict the scattering performance of an Intelligent Reflection Surface (IRS). An IRS creates controlled propagation conditions

MathTools: An Open API for Convenient MathML Handling

July 18, 2018
Author(s)
Howard S. Cohl, Andre Greiner Petter, Moritz Schubotz, Bela Gipp
Mathematical formulae carry complex and essential semantic in- formation in a variety of formats. Accessing this information with different sys- tems requires a standardized machine-readable format that is capable of encod- ing presentational and semantic

Towards Managing Age of Network State Information in Challenged Networks

July 8, 2018
Author(s)
Vladimir V. Marbukh
Age of Information (AoI) is a recently introduced metric for freshness of the real-time information, which requires frequent updates. This paper argues that AoI is useful not only for real-time network applications, but also for network state information
