User Guide for Prototype NSRL Portable Hashing Environment for NARA

December 12, 2005
Author(s)
John M. Tebbutt
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

Wavelength References for Interferometry in Air

December 12, 2005
Author(s)
Richard W. Fox, Brian R. Washburn, Nathan R. Newbury, Leo W. Hollberg
Interferometer sources with multiple known wavelengths can be provided by tunable lasers and calibrated optical reference cavities. The mode wavelengths are known by measuring a laser¿s frequency while locked to the mode in vacuum during a calibration step

Repair of Formamidopyrimidines in DNA Involves Different Glycosylases - Role of the OGG1, NTH1, and NEIL1 Enzymes

December 9, 2005
Author(s)
J Hu, N de Souza-Pinto, K Haraguchi, Barbara A. Hogue, Pawel Jaruga, M M. Greenberg, Miral M. Dizdar, V. Bohr
2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyG) and 4,6-diamino-5-formamidopyrimidine (FapyA), are formed abundantly in DNA of cultured cells or tissues exposed to ionizing radiation or to other free radical-generating systems. We show here that FapyG

Consumer Packaging Labeling Guide: Selling by Count

December 5, 2005
Author(s)
K M. Dresser
[Withdrawn (February 12, 2018)]This guide is intended to provide manufacturers, packers, distributors, and retailers of packaged products with information about the labeling requirements for commodities that are sold by count in the consumer marketplace

High-Bandwidth Coaxial PWB Transmission Line Probe

December 5, 2005
Author(s)
Nicholas Paulter, Robert H. Palm, Dwight D. Barry
The design and test of a wide bandwidth (3 dB attenuation bandwidth > 20 GHz) , 50 ohm , coaxial probe for the electrical characterization of printed wiring board (PWB) transmission lines is described. The probe makes thousands of repeated contacts, using

Three-dimensional Scanning Optical Tweezers

December 5, 2005
Author(s)
Thomas W. LeBrun, T W. Hwang, I Y. Park, Jun-Feng Song, Yong-Gu Lee, Nicholas G. Dagalakis, Cedric V. Gagnon, Arvind K. Balijepalli
There are several new tools for manipulating microscopic objects. Among them, optical tweezers (OT) has two distinguishing advantages. Firstly, OT can easily release an object without the need of a complicated detaching scheme. Secondly, it is anticipated

Electrodeposition of Cu on Ru Barrier Layers for Damascene Processing

December 2, 2005
Author(s)
Thomas P. Moffat, Marlon L. Walker, P J. Chen, John E. Bonevich, William F. Egelhoff Jr., Lee J. Richter, Daniel Josell, C A. Witt, T Aaltonen, M Ritala, M Leskela
Superfilling of sub-micrometer trenches by direct copper electrodeposition onto PVD and ALD Ru barriers is demonstrated. The Cu nucleation and growth mode is found to be sensitive to the oxidation state of the Ru surface as well as the copper deposition

A Feature-Based Approach to Embedded System Hardware and Software Co-Design

December 1, 2005
Author(s)
XuanFang Zha, Steven J. Fenves, Ram D. Sriram
An embedded system is a hybrid of hardware and softwarethat combines software flexibility and hardware real-time performance. The co-design of hardware and software is the most critical but difficult issue in embedded system design. In this paper, we

A Low Differential-Pressure Primary Standard for the Range 1 Pa to 13 kPa

December 1, 2005
Author(s)
A P. Miiller, Charles R. Tilford, Jay H. Hendricks
The National Institute of Standards and Technology (NIST) has completed the development of a low differential-pressure primary standard covering a range from 1 Pa to 13 kPa for operation with line pressures up to 200 kPa. The standard is based on a UIM

Amendments to the Fire Protection and Life Safety Provisions of the New York City Building Code by Local Laws Adopted While World Trade Center 1, 2, and 7 Were in Use. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST

December 1, 2005
Author(s)
J C. Razza, R A. Grill
This report was prepared to support the analysis of building and fire codes and practices of the National Institute of Standards and Technology (NIST) World Trade Center (WTC) Investigation. This report supports the objective of documenting the

Analysis and Design of Parallel Mechanisms with Flexure Joints

December 1, 2005
Author(s)
Byoung H. Kang, J Wen, Nicholas Dagalakis, Jason J. Gorman
Flexure joints are frequently used in precision-motion stages and microrobotic mechanisms due to their monolithic construction. The joint compliance, however, can affect the static and dynamic performance of the overall mechanism. In this paper, we

Analysis of Aircraft Impacts into the World Trade Center Towers (Appendixes) Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-2B)

December 1, 2005
Author(s)
Steven W. Kirkpatrick, R. Bocchieri, Fahim Sadek, Robert S. MacNeill, S Holmes, B D. Peterson, R W. Cilke, C Navarro
The baseline structural performance and aircraft impact damage analysis of the National Institute of Standards and Technology (NIST) Investigation of the World Trade Center (WTC) disaster had two primary tasks: (1) to develop reference structural models of

Analysis of Aircraft Impacts into the World Trade Center Towers (Chapters 9-11). Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-2B)

December 1, 2005
Author(s)
Steven W. Kirkpatrick, Robert T. Bocchieri, Fahim H. Sadek, Robert S. MacNeill, S Holmes, B D. Peterson, R W. Cilke, C Navarro
The objective of this report was to analyze the aircraft impacts into each of the World Trade Center (WTC) towers to provide the following: (1) estimates of probable damage to structural systems due to aircraft impact, including exterior walls, floor
