A Welding Data Dictionary

March 31, 2004
Author(s)
William G. Rippey
This data dictionary specifies data elements that are used to describe the design, fabrication and inspection of weldments. It comprises welding information from several authoritative sources. Data include description of component materials, details of

The New DOE Dishwasher Test Procedure: Development and First Results

March 29, 2004
Author(s)
Natascha S. Milesi-Ferretti, J Bowman, B Twigg
This paper summarizes the main changes to the test procedure for residential dishwashers and, Department of Energy s (DOE, Department) and industry s collaborative efforts to develop the data supporting those changes. It also quantifies energy consumption

Duplication of DYS19 Flanking Regions in Other Parts of the Y Chromosome

March 25, 2004
Author(s)
John M. Butler, R Schoske
During the testing of alternative primers for the Y chromosome short tandem repeat marker DYS19, a duplicated region of the Y chromosome was discovered. The duplicated sequence is contained within GenBank accession AC006335 and has a high degree of

Knowledge Representation for On-Road Driving

March 24, 2004
Author(s)
Christopher J. Scrapper Jr, Stephen B. Balakirsky
This paper will present a knowledge layer used by a hierarchical on-road driving planner that represents a road network as a discrete set of attributed road states. This knowledge layer facilitates the construction of a planning graph by providing

Building Regulatory Systems in a Post-September 11 World

March 22, 2004
Author(s)
Richard W. Bukowski
The September 11, 2001 attacks in the United States have initiated a significant discussion and rethinking among building regulators not only in the U.S., but also around the world. While most quickly state that regulations should not require that

Pumice Aggregates for Internal Water Curing

March 17, 2004
Author(s)
Pietro Lura, Dale P. Bentz, D Lange, K Kovler, A Bentur
A novel concept in internal curing of High Performance Concrete is based on dispersing very small, saturated lightweight aggregates (LWA) in the concrete, containing sufficient water to counteract self-desiccation. The amount of water in the LWA can be

Key metrology considerations for fiber Bragg grating sensors

March 14, 2004
Author(s)
Shellee D. Dyer, Paul A. Williams, Robert J. Espejo, Jonathan D. Kofler, Shelley M. Etzel
We discuss the current status of fiber Bragg grating (FBG) sensor metrology. High-accuracy wavelength measurements are critical for FBG strain sensors, because wavelength measurement uncertainties even as small as 1 pm lead to an uncertainty of nearly 1

The First Measurements with Octave-Spanning Femtosecond Laser Frequency Combs

March 13, 2004
Author(s)
Scott A. Diddams, David J. Jones
Here we describe in a historical manner the first optical frequency measurement measurements with octave-spanning frequency combs and the first measurement and stabilization of the carrier-envelope offset frequency for a train of femtosecond laser pulses.
