System-independent assessment of OCT axial resolution with a bar chart phantom

February 10, 2011
Author(s)
Robert C. Chang, Jeeseong Hwang, Christopher M. Stafford, Anant Agrawal, T. Joshua Pfefer, Megan Connors
We present a novel optical phantom approach for the characterization of OCT axial resolution and contrast via multilayered “bar charts.” We explored two methods to fabricate these phantoms: the first is based on a combinatorial methods approach from

Who is Who? Biometrics provides answers for public and private sectors

February 10, 2011
Author(s)
Fernando L. Podio
One of the critical issues related to secured Information Technology (IT) systems and applications is the verification of the users identity. Biometrics provides for secure transactions, positive identification and augmentation to human judgment. For

Comparison of the Sensitivity and Image Contrast in Spontaneous Raman and Coherent Stokes Raman Scattering Microscopy of Geometry Controlled Samples

February 9, 2011
Author(s)
Hyun M. Kim, Chris A. Michaels, Garnett W. Bryant, Stephan J. Stranick
We experimentally compare the performance and contrast differences between spontaneous and coherent Stokes Raman scattering microscopy. We demonstrate the differences on a series of geometry controlled samples that range in complexity from a point (array

Gradient Solvent Vapor Annealing of Block Copolymer Thin Films Using a Microfluidic Mixing Device

February 9, 2011
Author(s)
Kathryn L. Beers, Michael J. Fasolka, Julie N. Albert, Timothy D. Bogart, Ronald L. Lewis, J. Brian Hutchison, Bryan D. Vogt, Thomas H. Epps
Solvent vapor annealing (SVA) with solvent mixtures is a promising approach for controlling block copolymer thin film self-assembly. In this work, we present the design and fabrication of a solvent-resistant microfluidic mixing device to produce discrete

Internal Curing: A 2010 State-of-the-Art Review

February 9, 2011
Author(s)
Dale P. Bentz, Jason Weiss
The American Concrete Institute in 2010 defined internal curing as supplying water throughout a freshly placed cementitious mixture using reservoirs, via pre-wetted lightweight aggregates, that readily release water as needed for hydration or to replace

Semantic-based Optimal XML Schema Matching: A Mathematical Programming Approach

February 9, 2011
Author(s)
Jaewook Kim, Yun Peng, Nenad Ivezic, Jun H. Shin
We propose a novel solution for semantic-based XML schema matching, taking a mathematical programming approach. This method identifies the globally optimal solution for the problem of matching two XML schemas by reducing the tree-to-tree matching problem

Arithmetic Progressions on Edwards Curves

February 8, 2011
Author(s)
Dustin Moody
We look at arithmetic progressions on elliptic curves known as Edwards curves. By an arithmetic progression on an elliptic curve, we mean that the x-coordinates of a sequence of rational points on the curve form an arithmetic progression. Previous work has

Advanced Sensing Towards Improved Forklift Safety

February 4, 2011
Author(s)
Roger V. Bostelman, William P. Shackleford
The National Institute of Standards and Technology's Intelligent Systems Division has been researching advanced three-dimensional (3D) imaging sensors and their use in manufacturing towards improving forklift safety. Experiments are presented in this paper

Co-X Panel Discussion

February 4, 2011
Author(s)
Elena R. Messina, Brian A. Weiss, Rajmohan Madhavan
Robots as co-protectors, co-inhabitants, co-workers, co-integrants, or more generically, "Co-X" will improve effectiveness, efficiency, safety, security, and improve quality of life in the coming years. In-keeping with the theme of PerMIS'10, which

Controlling the Microstructure of Solution-Processible Small Molecules in Thin-Film Transistors through Substrate Chemistry

February 4, 2011
Author(s)
Regis J. Kline, Steven D. Hudson, Xinran Zhang, David J. Gundlach, Andrew Moad, Lee J. Richter, Oana Jurchescu, Thomas Jackson, Sanker Subramanian, John E. Anthony, Michael F. Toney
Solution-processible small molecules have tremendous potential for providing both high charge carrier mobility and low cost processing. This study outlines a detailed microstructural study of the effect of substrate chemistry on fluorinated 5,11-bis

Managing Security: The Security Content Automation Protocol

February 4, 2011
Author(s)
Shirley M. Radack, D. Richard Kuhn
Managing information systems security is an expensive and challenging task. Many different and complex software components- including firmware, operating systems, and applications-must be configured securely, patched when needed, and continuously monitored

Mixed Pallet Stacking: An Overview and Summary of the 2010 PerMIS Special Session

February 4, 2011
Author(s)
Stephen B. Balakirsky, Henrik I. Christensen, Thomas R. Kramer, Pushkar Kolhe, Frederick M. Proctor
Stacking boxes of various sizes and contents on pallets (i.e. making mixed pallets) is a primary method of preparing goods for shipment from a warehouse to a store or other distant site. A special session of the 2010 PERMIS workshop was held to examine

Absorption of Thermal Radiation by Burning Polymers

February 2, 2011
Author(s)
Gregory T. Linteris, Mauro Zammarano, Boris Wilthan, Leonard M. Hanssen
In large-scale fires, the input of energy to burning materials occurs predominantly by radiative transfer. The in-depth absorption of radiant energy by a polymer influences its ignition time and burning rate. The present investigation examines two methods

CHARACTERIZING FIREBRAND EXPOSURE DURING WILDLAND-URBAN INTERFACE FIRES.

February 2, 2011
Author(s)
Samuel L. Manzello, Ethan I. Foote, John Liu
This study examines the size distribution and other characteristics of firebrand exposure during the 2007 Angora Fire, a severe Wildland-Urban Interface (WUI) fire in California. Of the 401 houses that received direct interface fire exposure 61% were

EXPOSING SIDING TREATMENTS AND WALLS FITTED WITH EAVES TO FIREBRAND SHOWERS

February 2, 2011
Author(s)
Samuel L. Manzello, Sayaka S. Suzuki, Yoshihiko Hayashi
An experimental campaign was undertaken to determine vulnerabilities of siding treatments and walls fitted with eaves to firebrand bombardment using the NIST Dragon installed in the Building Research Institute’s Fire Research Wind Tunnel Facility (FRWTF)
