Propagation and Detection of Radio Signals Before, During, and After the Implosion of a 13-Story Apartment Building

May 1, 2005
Author(s)
Christopher L. Holloway, Galen H. Koepke, Dennis G. Camell, Catherine A. Remley, Dylan F. Williams, Susan A. Schima, Seturnino Canales, Douglas T. Tamura
In this report we investigate communications problems faced by emergency responders (firefighters and police) in disaster situations (i.e., collapsed buildings). A fundamental challenge to communications into large building structures is the strong

Application of Combinatorial Methods for the Testing of Adhesives

April 10, 2005
Author(s)
Christopher M. Stafford
This presentation will focus on the development and application of novel high-throughput platforms for both adhesion and mechanical property testing. For screening of commercial pressure sensitive adhesives, we are applying C&HT tools to conventional peel

Task Analysis of Autonomous On-road Driving

October 28, 2004
Author(s)
Tony Barbera, John A. Horst, Craig I. Schlenoff, David Aha
The Real-time Control System (RCS) Methodology has evolved over a number of years as a technique to capture task knowledge and organize it into a framework conducive to implementation in computer control systems. The fundamental premise of this methodology

Sooting Behavior of Ethanol Droplet Combustion at Elevated Pressures Under Microgravity Conditions

September 1, 2004
Author(s)
B D. Urban, K Kroenlein, A Kazakov, F L. Dryer, A Yozgatligil, M Y. Choi, Samuel Manzello, K O. Lee, R Dobashi
Liquid ethanol is widely used in practical fuels as a means to extend petroleum-derived resources or as a fuel additive to reduce emissions of carbon monoxide from spark ignition engines. Recent research has also suggested that ethanol and other oxygenates

Mitigation Strategies for Autogenous Shrinkage Cracking

August 1, 2004
Author(s)
O M. Jensen
As the use of high performance concrete has increased, problems with early-age cracking have become prominent. The reduction in w/c ratio, the incorporation of silica fume, and the increase in binder content of high performance concretes all contribute to

Wear Prediction of Ceramics

May 1, 2004
Author(s)
Stephen M. Hsu, M C. Shen
Advanced ceramics are increasingly being used for wear applications. The strength and fatigue resistance of ceramics have increased several fold in the last decade. Wear prediction of ceramics has become an important subject in these arenas. Ceramic wear

Evaluation and Selection in Product Design for Mass Customization

January 1, 2004
Author(s)
XuanFang Zha, Ram D. Sriram, W F. Lu, Fujun Wang
Mass customization has been identified as a competitive strategy by an increasing number of companies. Family-based product design has been recognized as an efficient and effective means to realize sufficient product variety to satisfy a range of customer

High-frequency noise measurements in spin-valve Devices

July 1, 2003
Author(s)
N. A. Stutzke, S. L. Burkett, Stephen E. Russek
High-frequency magnetic noise in magnetoresistive devices being developed for read-sensor and magnetic random access memory applications may present fundamental limitations on the performance of sub-micrometer magnetic devices. High- frequency magnetic

Progress in the Development of a Kinetic Database for Heptane Combustion

March 1, 2003
Author(s)
Wing Tsang
This paper deals with the development of a chemical kinetic database for use in the simulation of heptane combustion. The database consists of the thermodynamic properties of all reactants, intermediates and products and the consequences, in terms of rate

Overview: Damage in Brittle Layer Structures From Concentrated Loads

December 1, 2002
Author(s)
Brian R. Lawn, Y N. Deng, P Miranda, Antonia Pajares, H Chai, D H. Kim
In this article, we review recent advances in the understanding and analysis of damage initiation and evolution in laminate structures with brittle outlayers and compliant sublayers, in concentrated loading. The relevance of such damage to lifetime

The New Beamline 3 at SURF III for Source-Based Radiometry

March 1, 2002
Author(s)
Ping-Shine Shaw, D A. Shear, R Stamilio, Uwe Arp, Howard W. Yoon, Robert D. Saunders, Albert C. Parr, Keith R. Lykke
The Synchrotron Ultraviolet RAdiation Facility (SURF III) at the National Institute of Standards and Technology provides a unique opportunity for high-accuracy UV to infrared radiometry due to the 70-fold improvement in the uniformity of the magnetic field

A Combinatorial Methodology to Discovering the Material Factors Controlling Resist Line Edge Roughness, Shape, and Critical Dimension

January 28, 2002
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Ronald L. Jones, Eric K. Lin, Christopher Soles, Wen-Li Wu, D M. Goldfarb, M Angelopoulos
A combinatorial research methodology is discussed to determine the material factors that control line edge roughness (LER), shape, and critical dimension (CD) of developed photo-resist features. The approach involves generating a gradient of processing

Superconducting Transition Edge Sensor Bolometer Arrays for Submillimeter Astronomy

May 3, 2000
Author(s)
D. J. Benford, C. A. Allen, A. S. Kutyrev, S. H. Mosely, Rick A. Shafer, James A. Chervenak, Erich N. Grossman, Kent D. Irwin, John M. Martinis, Carl D. Reintsema
Studies of astrophysical emission in the far-infrared and submillimeter will increasingly require large arrays of detectors containing hundreds to thousands of elements. The last few years have seen the increasing from one to a few tens of bolometers on

Char Enhancing Approaches to Flame Retarding Polymers

January 1, 1999
Author(s)
Jeffrey W. Gilman, Takashi Kashiwagi, Richard H. Harris Jr., S M. Lomakin, J D. Lichtenhan, A. Bolf, P. Jones
Additives that increase the amount of charcoal-like residue or carbonaceous char that forms during polymer combustion are very effective fire retardants (FR). Our research efforts focus on reducing polymer flammability by promoting char formation. Our
