Author(s)
Nathan Episcopo, Po-Hao Chang, Thomas W. Heitmann, Kinley Wangmo, James M. Guthrie, Magdalena Fitta, Ryan Klein, Narayan Poudel, Krzysztof Gofryk, Rajendra R. Zope, Craig Brown, Harikrishnan S. Nair
Na 2Ni 2TeO 6 has a layered hexagonal structure with a honeycomb lattice constituted by Ni 2+ and a chiral charge distribution of Na + that resides between the Ni layers. In the present work, the antiferromagnetic transition temperature of Na 2Ni 2TeO 6 is

Benchmarking for keyword extraction methodologies in maintenance work orders

September 24, 2018
Author(s)
Thurston B. Sexton, Michael P. Brundage, Melinda Hodkiewicz, Thomas Smoker
Maintenance has largely remained a human-knowledge centered activity, with the primary records of maintenance activity being text-based maintenance work orders (MWOs) that attempt to encode the diagnostic processes of technicians. However, the bulk of

Measurement and Modeling of the Ability of Crack Fillers to Prevent Chloride Ingress into Mortar

Jose M. Borreguero, Junhong He, F. Meilleur, Kevin Weiss, Craig Brown, D. A. A. Myles, Kenneth W. Herwig, Pratul K. Agarwal
Abstract Proteins are dynamic objects, constantly undergoing conformational fluctuations, yet the linkage between internal protein motion and function is widely debated. This manuscript reports on the characterization of temperature-activated collective

Statistical Approaches in the NIST World Trade Center Analysis

October 1, 2005
Author(s)
James J. Filliben
The Federal Building and Fire Safety Investigation of the World Trade Center Disaster is currently essentially completed. The pre-collapse progression was extremely complicated, with structural, thermal, dynamic and stochastic interdependencies across time

Sorptivity-Based Service Life Predictions for Concrete Pavements

September 1, 2001
Author(s)
Dale P. Bentz, M A. Ehlen, Chiara F. Ferraris, Edward J. Garboczi
The degradation of concrete pavements is often controlled by the transport of a deleterious species (chloride or sulfate ions, or water in the case of freeze/thaw) into the concrete. With this in mind, a three-year research project, funded by the Federal
