On-Chip Integrated Silicon Photonic Thermometers

September 1, 2015
Author(s)
Nikolai N. Klimov, Thomas P. Purdy, Zeeshan Ahmed
The fundamental limitations of resistance-based thermometry and the desire to reduce sensor ownership have produced considerable interest in the development of photonics-based temperature sensors as an alternative to resistance thermometers. Photonic

Improving Clinical Workflow in Ambulatory Care: Implemented Recommendations in an Innovation Prototype for the Veterans Health Administration

August 3, 2015
Author(s)
Svetlana Z. Lowry, Emily S. Patterson, Mala Ramaiah, Michael C. Gibbons, David Brick, Robert Calco, Greg Matton, Anne Miller, Ellen Makar, Jorge Ferrer
The National Institute of Standards and Technology (NIST) presented targeted recommendations from human factors workflow methods that could be used in ambulatory (outpatient) care settings to improve the fit of the Electronic Health Record (EHR) with

Aging of Polymeric Films used in Protective Glazing Systems

July 7, 2015
Author(s)
Christopher C. White, Donald L. Hunston, Kar T. Tan
The toughness of polymer and glass laminates or win-dow glazing, are used to protect buildings and occupants from shattered glass resulting from natural disasters (e.g., hurricanes, tornadoes, seismic events), and intentional events (e.g., robbery

Multi-scale measurement for tensile behaviors of glass fiber composites at high rate loading: Fiber fragmentation behaviors in epoxy resin

May 19, 2015
Author(s)
Jae Hyun Kim, Steven P. Mates, Nathanael A. Heckert, Walter G. McDonough, Gale A. Holmes
High strength and light weight composite materials used in various structural components of aviation and automotive applications deform under high rate loading conditions during collision. Since composite structures using continuous fibers are constituted

Post-process machining of additive manufactured stainless steel

April 29, 2015
Author(s)
Brandon M. Lane, Shawn P. Moylan, Eric P. Whitenton
Due to the poorer surface finish and geometric accuracy of additive manufactured (AM) parts compared to machined parts, it is inevitable that parts fabricated through AM processes will require post-process machining. This problem was identified early by

Real-Time Access Control Rule Fault Detection Using a Simulated Logic Circuit

February 3, 2014
Author(s)
Chung Tong Hu, Karen Scarfone
Access control (AC) policies can be implemented based on different AC models, which are fundamentally composed by semantically independent AC rules in expressions of privilege assignments described by attributes of subjects/attributes, actions, objects

Structural Design for Disaster Resilience

October 28, 2013
Author(s)
Fahim H. Sadek, Joseph Main, John L. Gross, Therese P. McAllister
This paper presents a brief overview of research at the National Institute of Standards and Technology (NIST) on disaster resilience of buildings, infrastructure, and communities, including component programs and projects. NIST's efforts aim at developing

Parahydrogen-enhanced zero-field nuclear magnetic resonance

May 1, 2011
Author(s)
Svenja A. Knappe, T. Theis, P. Ganssle, G Kervem, M Ledbetter, D Budker, A Pines, John E. Kitching
Nuclear magnetic resonance (NMR) is a powerful analytical tool for determination of molecular structure and function, with broad impact in biology, medicine, materials science, and fundamental research. Conventionally, NMR is performed in multiTesla

Coupled quantized mechanical oscillators

March 10, 2011
Author(s)
Kenton R. Brown, Christian Ospelkaus, Yves Colombe, Andrew C. Wilson, Dietrich G. Leibfried, David J. Wineland
The harmonic oscillator is one of the simplest physical systems but also one of the most fundamental. It is ubiquitous in nature, often serving as an approximation for a more complicated system or as a building block for larger models. Realizations of

Reliability Issues of SiC MOSFETs: A Technology for High Temperature Environments

September 20, 2010
Author(s)
Liangchun (. Yu, Greg Dunne, Kevin Matocha, Kin P. Cheung, John S. Suehle, Kuang Sheng
The wide-bandgap nature of silicon carbide (SiC) makes it an excellent candidate for applications where high temperature is required. The MOS-controlled power devices are the most favorable structure, however, it is widely believed that silicon oxide on

Calculation of pulse parameters and propagation of uncertainty

March 1, 2009
Author(s)
Paul D. Hale, Chih-Ming Wang
The fundamental starting point for the analysis of all two-state waveforms is the determination of the low- and highstate levels. This is a two-step process. First, the data are grouped into points belonging to each state, and second, the value of each

Effect of CuO Nanolubricant on R134a Pool Boiling Heat Transfer

January 6, 2009
Author(s)
Mark A. Kedzierski, M Gong
This paper quantifies the influence of CuO nanoparticles on the boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based nanofluid

Preface to Dislocatrions 2000 Proceedings

October 16, 2008
Author(s)
Lyle E. Levine, L -. Kubin, R -. Becker
During the 1950's and 1960's, a widespread international effort was underway to lay the foundations for a fundamental, dislocations-based understanding of plastic deformation and strain hardening. This effort lagged, however, as the existing theoretical

Realizing the SI in the 21st Century at NIST

October 16, 2008
Author(s)
K B. Gebbie
As it embarks on its second 100 years, the National Institute of Standards and Technology is developing new approaches to realizing and disseminating the SI. Efforts to improve the realization of the second include development of a laser-cooled cesium

Surface Effects on Capped and Uncapped Nanocrystals

October 16, 2008
Author(s)
Garnett W. Bryant, W Jaskolski
Surface effects significantly influence the functionality of semiconductor nanocrystals. A theoretical understanding of these effects requires an atomic-scale description of the surface. We present an atomistic tight-binding theory of the electronic and
