Measurement Uncertainty in Cell Image Segmentation Data Analysis

August 13, 2013
Author(s)
Jin Chu Wu, Michael W. Halter, Raghu N. Kacker, John T. Elliott, Anne L. Plant
Cell image segmentation is a part of quantitative studies regarding cell movement and cell behavior, and it plays a critical role in molecular biology and cellular biochemistry. Therefore, it is fundamentally important to evaluate the performance levels of

Status and Opportunities to Support Product Category Rules in the U.S.

August 12, 2013
Author(s)
Rita Schenck
Environmental Product Declarations (EPDs) are a kind of ecolabel that discloses the environmental impacts of a product over its life cycle, using the science of life cycle assessment. EPDs hold out the promise of supporting science based decisions in

Temperature-Programmed Electrospray-Differential Mobility Analysis for Characterization of Ligated Nanoparticles in Complex Media

August 12, 2013
Author(s)
De-Hao D. Tsai, Frank W. DelRio, John M. Pettibone, Pin A. Lin, Jiaojie Tan, Michael R. Zachariah, Vincent A. Hackley
In this study, an electrospray-differential mobility analyzer (ES-DMA) was operated with an aerosol flow-mode, temperature-programmed approach to enhance its ability to characterize the particle size distributions (PSDs) of nanoscale particles (NPs) in the

Through-focus scanning optical microscopy for defect inspection of EUV masks

August 12, 2013
Author(s)
Ravikiran Attota, Vibhu Jindal
The TSOM method provides three-dimensional nanoscale metrology using a conventional optical microscope. Substantial improvements in defect detectability using the TSOM method will be presented. The TSOM method shows potential to (i) detect phase defects on

Evaluating Feedback Systems for Residential Building Energy Monitoring

August 10, 2013
Author(s)
Wenqi Guo, Tania Ullah, MengChu Zhou
Rising global energy demand, increasing electricity prices, and the limitation of natural resources have led to increased interest in energy monitoring of residential buildings. Much research has been done to examine the effect of energy use feedback to

Multilingual Summarization: Dimensionality Reduction and a Step Towards Optimal Term Coverage

August 9, 2013
Author(s)
Yi-Kai Liu, John M. Conroy, Sashka T. Davis, Jeff Kubina, Dianne P. O'Leary, Judith D. Schlesinger
In this paper we present three term weighting approaches for multi-lingual document summarization and give results on the DUC 2002 data as well as on the 2013 Multilingual Wikipedia feature articles data set. We introduce a new interval-bounded nonnegative

On the Link Between Insertion Loss and Lower Bound of Efficiency

August 9, 2013
Author(s)
Levon Barsikyan, Jason Coder, Mark Golkowski, John M. Ladbury
We investigate the effect of chamber loss on the recently developed 2-port antenna model and the associated method of determining antenna efficiency. The loss in the reverberation chamber was controlled using microwave absorbing foam creating four

August 7, 2013
Author(s)
Svetlana Z. Lowry, Mala Ramaiah, Ant Ozok, Ayse P. Gurses, Michael C. Gibbons, David Brick, Emily S. Patterson, Debora Simmons
On April 19, 2013, 47 participants met at the Johns Hopkins Armstrong Institute for Patient Safety and Quality, Baltimore, MD, for a NIST-sponsored full-day EHR Usability and Patient Safety Roundtable: Supporting Patient Safety Through EHR Design. In

A Model Based Continuous Improvement Methodology for Sustainable Manufacturing

August 7, 2013
Author(s)
Sanjay Jain, Guodong Shao, Alexander Brodsky, Frank H. Riddick
This paper proposes a model based continuous improvement methodology to support efforts to achieve sustainable manufacturing, i.e., to increase efficiency and reduce environmental impact of manufacturing systems. Past efforts have provided guidance at a

A Survey of Standards for Product Lifecycle Management of Structural Composites

August 7, 2013
Author(s)
Christopher U. Brown, Joshua Lubell, Robert R. Lipman, Gaurav Ameta
Composites are needed when designing components with a high strength (along a particular direction) to weight ratio. Composites are widely used in the automotive, sports and aerospace industries. Designing a composite component requires highly concurrent

Dietary Supplement Laboratory Quality Assurance Program: Exercise I Final Report

August 7, 2013
Author(s)
Melissa M. Phillips, Catherine A. Rimmer, Laura J. Wood, Karen E. Murphy, Katherine E. Sharpless, Thomas W. Vetter
The NIST Dietary Supplement Laboratory Quality Assurance Program (DSQAP) was established in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS) in 2007 to enable members of the dietary supplements community to

IDENTIFYING THE MATERIAL INFORMATION REQUIREMENTS FOR SUSTAINABLE DECISION MAKING

August 7, 2013
Author(s)
Anantha Narayanan Narayanan, Paul W. Witherell, Jae H. Lee, Katherine C. Morris, Sudarsan Rachuri
Materials play a central role in product manufacturing, contributing to each phase of product development in the form of either a component or process material. As the product revolves around materials, so does much of the product information. Material

Micro-fabricated stylus ion trap

August 7, 2013
