Estimation of the Enhancement Factor for Mercury in Air

March 31, 2010
Author(s)
Allan H. Harvey
A combination of classical thermodynamics and molecular theory was used to calculate the enhancement factor (ratio of partial pressure to saturated vapor pressure) for liquid mercury in equilibrium with air at standard atmospheric pressure in the

Performance Evaluation and Benchmarking of Robotic and Automation Systems

March 31, 2010
Author(s)
Rajmohan Madhavan, Elena R. Messina, Angel P. Del Pobil
The Technical Committee on Performance Evaluation and Benchmarking for Robotic and Automation Systems (TC-PEBRAS) was approved at the Technical Activities Board (TAB) meeting held at the 2009 International Conference on Robotics and Automation (ICRA) in

Proximity-associated errors in contour metrology

March 31, 2010
Author(s)
John S. Villarrubia, Ronald G. Dixson, Andras Vladar
In contour metrology the CD-SEM (critical dimension scanning electron microscope) assigns a continuous boundary to extended features in an image. The boundary is typically assigned as a simple function of the signal intensity, for example by a brightness

Sensitivity of coherent dual-comb spectroscopy

March 31, 2010
Author(s)
Nathan R. Newbury, Ian R. Coddington, William C. Swann
Coherent dual comb spectroscopy can provide high-resolution, high-accuracy measurements of a sample response in both magnitude and phase. We discuss the achievable signal-to-noise ratio (SNR) due to both additive white noise and multiplicative noise, and

A Report on the Privilege (Access) Management Workshop

March 30, 2010
Author(s)
Annie W. Sokol
This document is based on the discussions and conclusions of the Privilege (Access) Management Workshop held on 1-3 September, 2009 at the Gaithersburg, Maryland facilities of the National Institute of Standards and Technology (NIST), sponsored by NIST and

Analysis of photoconductive gain as it applies to single-photon detection

March 30, 2010
Author(s)
Mary A. Rowe, G. M. Salley, E. J. Gansen, Shelley M. Etzel, Sae Woo Nam, Richard P. Mirin
We detail a mathematical framework for photoconductive gain applied to the detection of single photons. Because photoconductive gain is derived from the ability to measure current change for an extended period, its magnitude is reduced as detection speed

Data Loss Prevention

March 29, 2010
Author(s)
Simon Liu, D. Richard Kuhn
In today's digital economy, data enters and leaves enterprises' cyberspace at record rates. For a typical enterprise, millions of emails are sent and received and thousands of files are downloaded, saved or transferred via various channels or devices on a

Effect of N-Terminal Glutamic Acid and Glutamine on Fragmentation of Peptide Ions

March 27, 2010
Author(s)
Bhaskar Godugu, Pedatsur Neta, Yamil Simon, Stephen Stein
A prominent dissociation path for electrospray generated tryptic peptide ions is the dissociation of the peptide bond linking the second and third residues from the amino-terminus. The formation of the resulting b 2 and y n-2 fragments has been

AP210 Edition 2 Concept of Operations

March 26, 2010
Author(s)
Kevin G. Brady, Jamie Stori, Thomas Thurman
One of the most prevalent requirements of manufacturing industries today is the need to exchange and share product information within and between enterprises. This becomes almost impossible without a standardized, computer-interpretable method of

Building Information Exchange for Fire Responders Workshop: Proceedings

March 26, 2010
Author(s)
Jason D. Averill, David G. Holmberg, Alan B. Vinh, William D. Davis
Presently, there is no integrated solution for delivering building data into the hands of emergency responders. Technically, there are many challenges to collect, format, process, integrate and transport building data out of the building. Beyond this, the

N-Pyrrolidine Functionalized C 60 -Fullerenes/Epoxy Nanocomposites

March 26, 2010
Author(s)
Mickey Richardson, Eun S. Park, Jaehyun Kim, Gale A. Holmes
A small series of functionalized C60-fullerene/epoxy nanocomposites were prepared, and their respective ultimate tensile strengths were determined. The functionalization route of the fullerenes was performed using the well-known Prato reaction, with

Wrinkling and Strain Softening in Single-Wall Carbon Nanotube Membranes

March 26, 2010
Author(s)
Erik K. Hobbie, Daneesh O. Simien, Jeffrey A. Fagan, JiYeon Huh, Jun Y. Chung, Steven D. Hudson, Jan Obrzut, Jack F. Douglas, Christopher M. Stafford
Ultrathin layers of single-wall carbon nanotubes (SWCNTs) show considerable promise for applications ranging from fuel-cell membranes and biochemical sensors to bioactive films and transparent electrodes. The high conductivity and extreme anisotropy of

A RESTful Web Service for Virtual Supply Chain Time Management

March 25, 2010
Author(s)
Guillaume Radde
A common issue when building distributed simulations is the issue of time management. Each discrete event simulation has its own notion of time, and a mechanism needs to be set up to allow each simulation to run at the same pace. Different architectures

Methods for TEM analysis of NISTs SWCNT SRM

March 25, 2010
Author(s)
Roy H. Geiss, Elisabeth Mansfield, Jeffrey A. Fagan
The National Institute of Standards and Technology (NIST) is developing a series of single-walled carbon nanotube, SWCNT, reference materials, RMs, to provide researchers with well characterized materials for their applications. The SWCNT reference
