Detecting Carbon in Carbon: Application of Differential Charging to Obtain Information on the Chemical Identity and Spatial Location of Carbon Nanotube Aggregates in Composites by Imaging X-ray Photoelectron Spectroscopy

October 24, 2015
Author(s)
Justin M. Gorham, William A. Osborn, Jeremiah W. Woodcock, Keana C. Scott, John M. Heddleston, Angela R. Hight Walker, Jeffrey W. Gilman
The surface contributions and dispersion properties of multiwalled carbon nanotubes (MWCNT) within a composite are important measurements to perform on nano-enabled products in order to help answer environmental health and safety questions associated with

A Sensor-Based Method for Diagnostics of Machine Tool Linear Axes

October 23, 2015
Author(s)
Gregory W. Vogl, Brian A. Weiss, Alkan Donmez
A linear axis is a vital subsystem of machine tools, which are vital systems within many manufacturing operations. When installed and operating within a manufacturing facility, a machine tool needs to stay in good condition for parts production. All

Adaptive Multi-scale PHM for Robotic Assembly Processes

October 23, 2015
Author(s)
Benjamin Y. Choo, Peter A. Beling, Amy LaViers, Jeremy Marvel, Brian A. Weiss
Adaptive multi-scale prognostics and health management (AM-PHM) is a methodology designed to support PHM in smart manufacturing systems. AM-PHM is characterized by its incorporation of multi-level, hierarchical relationships and PHM information gathered

Linear Temporal Logic (LTL) Based Monitoring of Smart Manufacturing Systems

October 23, 2015
Author(s)
Gerald Heddy, Umer Huzaifa, Peter A. Beling, Yacov Haimes, Jeremy Marvel, Brian A. Weiss, Amy LaViers
The vision of Smart Manufacturing Systems (SMS) includes collaborative robots that can adapt to a range of scenarios. This vision requires a classification of multiple system behaviors, or sequences of movement, that can achieve the same high-level tasks

Measurement Science for Prognostics and Health Management for Smart Manufacturing Systems: Key Findings from a Roadmapping Workshop

October 23, 2015
Author(s)
Brian A. Weiss, Gregory W. Vogl, Moneer Helu, Guixiu Qiao, Joan Pellegrino, Mauricio Justiniano, Anand Raghunathan
The National Institute of Standards and Technology (NIST) hosted the Roadmapping Workshop - Measurement Science for Prognostics and Health Management for Smart Manufacturing Systems (PHM4SMS) in Fall 2014 to discuss the needs and priorities of stakeholders

A Source for Mesoscopic Quantum Optics

October 22, 2015
Author(s)
Georg Harder, Timothy J. Bartley, Adriana Lita, Sae Woo Nam, Thomas Gerrits, Christine Silberhorn
The nature of quantum decoherence renders the observation of nonclassical features/properties in large systems increasingly difficult. Optical states are a good candidate to observe nonclassical features since 5 they are less susceptible to environmental

De-Identification of Personal Information

October 22, 2015
Author(s)
Simson L. Garfinkel
Abstract: De-identification removes identifying information from a dataset so that individual data cannot be linked with specific individuals. De-identification can reduce the privacy risk associated with collecting, processing, archiving, distributing or

Hydrostatic Pressure Promotes Domain Formation in Model Lipid Raft Membranes

October 22, 2015
Author(s)
David Worcester, Michael Weinrich
Neutron diffraction measurements demonstrate that hydrostatic pressure promotes Liquid-ordered (L 0) domain formation in lipid membranes of both oriented multi-layers and unilamellar vesicles made of a canonical ternary lipid mixture for which demixing

Mitigation of autogenous shrinkage in repair mortars via internal curing

October 22, 2015
Author(s)
Dale P. Bentz, Scott Z. Jones, Max A. Peltz, Paul E. Stutzman
Repair mortars are being used with increasing frequency to maintain the aging US infrastructure. Durability is a key concern for such repair materials and both their volume stability and bond to the existing concrete are key attributes, the former to avoid
