Author(s)
John M. Tebbutt, Anthony V. Cincotta
The National Software Reference Library (NSRL) of the U.S. National Institute of Standards and Technology (NIST) collects software from various sources and publishes file profiles computed from this software (such as MD5 and SHA-1 hashes) as a Reference

Segmentation for Robust Tracking in the Presence of Severe Occlusion

December 3, 2001
Author(s)
Camillo A. Gentile, M Sznaier, O Camps
Tracking an object in a sequence of images can fail due to partial occlusion or clutter. Robustness can be increased by tracking a set of parts, provided that a suitable set can be identified. In this paper we propose a novel segmentation, specifically

Thermal Measurements for Fire Fighters' Protective Clothing

The Guide is intended to provide information on the U.S. standards system, entities within that system, and different types of documentary standards. It includes descriptions of performance and design standards; volumtary consensus standards; defense

Burning Behavior of Selected Automotive Parts From a Sports Coupe.

December 1, 2001
Author(s)
Thomas J. Ohlemiller, John R. Shields
Selected functional parts from a sports coupe were subjected to a gas: flame ignition source and burned in a manner that allowed measurement of the resulting total heat release rate and heat fluxes to the surroundings. This is the second part of a study

Characterization and Modeling of Silicon-Carbide Power Devices

December 1, 2001
Author(s)
Allen R. Hefner Jr., David W. Berning, Ty R. McNutt, Alan Mantooth, Jih-Sheng Lai, Ranbir Singh
New Power semiconductor devices have begun to emerge that utilize the advantages of silicon carbide (SiC). As SiC power device types are introduced, circuit performance and reliability characterization are required for system designers to adopt the new

Characterization of Particulate From Fires Burning Silicone Fluids

December 1, 2001
Author(s)
Y Sivathanu, Anthony P. Hamins, George W. Mulholland, Takashi Kashiwagi, R Buch
The optical properties of particulate emitted from fires burning two distinct polydimethylsiloxane fluids (D4 and M2 or MM, where D=(CH3)2SiO and M=(CH3)3SiO2) were obtained using a transmission cell-reciprocal nephelometer in conjunction with gravimetric

Coherent Raman and Infrared Studies of Sulfur Trioxide

December 1, 2001
Author(s)
E T. Chrysostom, N Vulpanovici, Tony Masiello, J Barber, J W. Niblez, A Weber, A G. Maki, Thomas A. Blake
High resolution (0.001 cm -1) coherent anti-Stokes Raman scattering (CARS) was used to observe the Q-branch structure of the IR-inactive Ņ 1 symmetric stretching mode of 32S 160 3 and its various 18O isotopomers. The Ņ 1 spectrum of 32S 160 3 reveals two

Author(s)
Wing Tsang, Robert E. Huie, Jeffrey A. Manion
The next two issues of the International Journal of Chemical Kinetics are dedicated to Prof. Simon H. Bauer on the occasion of his 90th birthday. These issues contain a number of papers by his students and colleagues who have built on his pioneering

Confinement Effects on the Spatial Extent of the Reaction Front in Ultrathin Chemically Amplified Photoresists

December 1, 2001
Author(s)
D L. Goldfarb, M Angelopoulos, Eric K. Lin, Ronald L. Jones, Christopher Soles, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Wen-Li Wu
Sub-100 nm lithography poses strict requirements on photoresist material properties and processing conditions to achieve necessary critical dimension (CD) control of patterned structures. As resist thickness and feature linewidth decrease, fundamental

Contact Tube Temperature During GMAW

December 1, 2001
Author(s)
G Adam, Thomas A. Siewert, Timothy P. Quinn, D P. Vigliotti
The rate of heating and the maximum temperature reached by the contact tube during gas metal arc welding (GMAW) is quantified. We studied the effect of changes in the contact-tube-to-work distance (CTWD), voltage, welding wire feed speed, gas flow rate

Convalent Cationization Method for the Analysis of Polyethylene by Mass Spectrometry

December 1, 2001
Author(s)
Barry J. Bauer, William E. Wallace, B M. Fanconi, Kathleen M. Flynn
Polyethylene and other polyolefins have not been amenable to mass spectrometric characterization of molecular mass distribution due to the ineffectiveness of conventional methods of cationization. The lack of polar groups, unsaturation, and aromaticity

Critical Dimension Metrology and the Scanning Electron Microscope

December 1, 2001
Author(s)
Michael T. Postek, Andras Vladar
Metrology is a principal enabler for the development and manufacture of current and future generations of semiconductor devices. With the potential of 130-nm, and 100-nm, and even smaller linewidths and high-aspect-ratio structures, the scanning electron
