231 - Standard Reference Data Program

October 16, 2008
Author(s)
J R. Rumble
Makes reliable scientific and technical data available to researchers, engineers and many other users. The program generates sets of critically evaluated data and widely disseminates them both as computer databases and publications. The breadth and scope

Evaluation of Methods for Determining the Yoshida-Uemori Combined Isotropic/Kinematic Hardening Model Parameters from Tension-Compression Tests of Advanced Lightweighting Materials

August 19, 2022
Author(s)
Dilip K. Banerjee, William E. Luecke, Mark Iadicola, Evan Rust
The performance of two methods, termed Manual and Optimization, for determining the values of the constitutive-model parameters for Yoshida-Uemori (Y U) isotropic-kinematic hardening model was evaluated. The Y U parameters were determined for two 6000

Software Independent Data Mapping Tool for Structural Fire Analysis

March 12, 2014
Author(s)
Dilip K. Banerjee
In order to model the structural behavior under fire, three separate analyses need to be conducted: a) fire propagation and growth (fire modeling), b) transient heat transfer in structural members due to fire, and c) structural analysis to account for both

Database of Ab Initio L-edge X-ray Absorption Near Edge Structure

June 11, 2021
Author(s)
Yiming Chen, Chi Chen, Chen Zheng, Shyam Dwaraknath, Matthew K. Horton, Jordi Cabana, John J. Rehr, John Vinson, Alan K. Dozier, Kristin A. Persson, Shyue P. Ong
The L-edge X-ray Absorption Near Edge Structure (XANES) is widely used in the characterization of transition metal compounds. Here, we report the development of a database of computed L-edge XANES using the multiple scattering theory-based FEFF9 code. The

R Implementation of a Polyhedral Approximation to a 3D Set of Points Using the Alpha-Shape

January 1, 2014
Author(s)
Thomas V. Lafarge, Beatriz Pateiro Lopez, Antonio M. Possolo, Joy P. Dunkers
This work describes the implementation in R of the alpha-shape of a finite set of points in three-dimensional space. This geometric construct generalizes the convex hull and estimates the shape of non-convex and even non-connected sets in 3D, given random

Three-dimensional Shape Metrology for Tissue Engineering

April 21, 2012
Author(s)
Joy P. Dunkers, Antonio M. Possolo, Thomas V. Lafarge, Beatriz Pateiro-Lopez, Jeffrey Coles, Carl G. Simon Jr.
The physical and chemical properties of a tissue scaffold influences cell response and therefore the success of the resulting tissue construct. Scaffold structure from nanometers to millimeters can direct cell behavior, from viability to proliferation to

Kinetic Spanning Trees for Minimum-Power Routing in MANETS

May 30, 2002
Author(s)
Camillo Gentile, R E. Van Dyck
… until the time of the next node trajectory change. By computing the sequence of trees using one execution of the distributed routing algorithm, in contrast to computing the tree for a single time instant, the number of …

Intelligent Control For Off-Road Driving

February 1, 2002
Author(s)
Karl Murphy, Marilyn N. Abrams, Stephen B. Balakirsky, Tommy Chang, Tsai Hong Hong, Alberto Lacaze, Steven Legowik
The NIST robot vehicle, a HMMWV with sensors and computer controlled actuators, detects how traversable the terrain is near the vehicle and computes its path and velocity accordingly. During tests the vehicle drives through the back fields of NIST at
