Sample Preparation Protocols for Realization of Reproducible Characterization of Single-walled Carbon Nanotubes

December 1, 2009
Author(s)
Angela R. Hight Walker, Jeffrey A. Fagan, Stephanie A. Hooker, Michael T. Postek, Stephen A. Wise, Andras Vladar, Rolf L. Zeisler
Harmonized sample pre-treatment is an integral first step in ensuring metrological quality of measurements as regards repeatability, inter-laboratory reproducibility and commutability. The development of standard preparation methods for SWCNT samples is

Sensing the Insulin Signaling Pathway with an Antibody Array

December 1, 2009
Author(s)
Hua-Jun He, Y Zong, Michel Bernier, Lili Wang
Defects within the insulin signaling pathways are a major locus for the development of insulin resistance and type 2 diabetes. The phorbol 12-myristate 13-acetate (PMA) is commonly described as a mediator of insulin resistance through the activation of the

STEPNC++ - An Effective Tool for Feature-based CAM/CNC

December 1, 2009
Author(s)
John L. Michaloski, Thomas R. Kramer, Frederick M. Proctor, Xun Xu, Sid Venkatesh, David Odendahl
This chapter discusses the realization of direct translation of feature-based CAM files into feature-based CNC part program files. The information infrastructure that allows this to happen is STEP-NC, as described by ISO 14649 Parts 10 and 11. Among the

Traceability for Ballistics Signature Measurements in Forensic Science

December 1, 2009
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Susan M. Ballou, Li Ma, Thomas Brian Renegar, Xiaoyu Alan Zheng, Martin Ols
The National Institute of Standards and Technology (NIST) in collaboration with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has developed the Standard Reference Material (SRM) 2460 Bullets and 2461 Casings. NIST has also developed a 2D

A Quality Pre-Processor for Biological Cell Images

November 30, 2009
Author(s)
Adele P. Peskin, Karen Kafadar, Alden A. Dima
We have developed a method to rapidly test the quality of a biological image, to identify appropriate segmentation methods, if any, that will render high quality segmentations for the cells within that image. The key contribution is the development of a

FIXED-POINT PROPERTIES OF H2O AND D2O

November 30, 2009
Author(s)
Allan Harvey
Tables for inclusion in the 2010-2011 edition of the CRC Handbook of Chemistry and Physics include: Fixed-point properties of H2O and D2O; Properties of ice and supercooled water; Vapor pressure of ice; Melting point of ice as a function of pressure

IPv6 Test Methods: General Description and Validation

November 30, 2009
Author(s)
J. S. Nightingale
The USG profile for IPv6 specifies requirements for host, router and network protection devices (NPD) and this document specifies the validation requirements for test methods and test specifications used to test these devices. It has become the practice

Rapidly-Deployable Mesh Network Testbed

November 30, 2009
Author(s)
Michael R. Souryal, Nader Moayeri, Andreas Wapf
This paper describes a wireless mesh network testbed for research in rapid deployment and auto-configuration of mesh nodes. Motivated by the needs of first responders and military personnel arriving to an incident area, we developed and tested an automated

Rethinking Egress: A Vision for the Future

November 30, 2009
Author(s)
Jason D. Averill, Richard D. Peacock
New technologies and research are redefining the state-of-the-art in building evacuation. The time is right to rethink the entire infrastructure of egress from buildings in light new opportunities to address the economic and life-safety issues

Stochastic Modeling of Coaxial-Connector Repeatability Errors

November 30, 2009
Author(s)
Arkadiusz C. Lewandowski, Dylan F. Williams
We propose a new description of connector or repeatability errors for coaxial one-port devices. Our approach is based on a stochastic model constructed as a luped-element equivalent circuit with randomly varying frequency-independent parameters. We

The Benefits of Network Coding over a Wireless Backbone

November 30, 2009
Author(s)
Hui Guo, Yi Qian, Kejie Lu, Nader Moayeri
Network coding is a promising technology that can effectively improve the efficiency and capacity of multi-hop wireless networks by exploiting the broadcast nature of the wireless medium. However, existing studies have demonstrated that the benefits of

USGv6 Testing Program User's Guide

November 30, 2009
Author(s)
J. S. Nightingale
OMB Memorandum M-05-22 directed the National Institute of Standards and Technology (NIST) to develop the technical infrastructure (standards and testing) necessary to support wide scale adoption of IPv6 in the US Government (USG). Upon detailed inspection
