Thermal Response and Inequivalence of Pulsed Ultraviolet-Laser Calorimeters

January 1, 2002
Author(s)
D X. Chen, Marla L. Dowell, Christopher L. Cromer, Nien F. Zhang
A finite element model has been developed to study the thermal response of pulsed-laser calorimeters. Comparisons between pulsed- and average-laser power heating will be shown. Comparisons between laser and electrical heating will be presented and the

Thermal Shock Resistance of Silicon Nitrides Using an Indentation-Quench Test

January 1, 2002
Author(s)
S K. Lee, J D. Moretti, Brian R. Lawn
The thermal shock resistance of silicon nitrides is investigated using an indentation-quench procedure. Four grades of commercially available silicon nitrides with different microstructures are investigated. The extension of Vickers radial cracks is

Thermodynamics of Metal Agent Fire Extinguishment

January 1, 2002
Author(s)
J D. Mather, R E. Tapscott
The thermodynamics of oxides, carbonates, halides and related metal compounds involved in extinguishment by dry chemicals and metal agents has been analyzed. It is shown that lattice energies play an important role in determining the extinguishment

Toward Traceability for At Line AFM Dimensional Metrology

January 1, 2002
Author(s)
Ronald G. Dixson, Angela Guerry, Marylyn H. Bennett, Theodore V. Vorburger, Michael T. Postek
The in-line and at-line measurement tools for critical dimension (CD) metrology in semiconductor manufacturing are technologically advanced instruments that exhibit excellent measurement repeatability--below 1 nm in some cases. Accuracy, however, is

Transformation, Ranking, and Clustering for Face Recognition Algorithm Performance

January 1, 2002
Author(s)
Stefan D. Leigh, Nathanael A. Heckert, Andrew L. Rukhin, P J. Phillips, Patrick J. Grother, E M. Newton, M Moody, K Kniskern, S Heath
The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank-based scores such a cumulative match score and receiver operating characteristic. This paper

Transitions Between Inherent Structures in Water

January 1, 2002
Author(s)
N Giovambattista, Francis W. Starr, F Sciortino, S V. Buldyrev, H E. Stanley
The energy landscape approach has been useful to help understand the dynamic properties of supercooled liquids and their connection between these properties and thermodynamics. The analysis in numerical models of the inherent structure (IS) trajectories --

Transverse compressive stress, fatigue, and magnetic substrate effects on the critical current density of Y-Ba-Cu-O coated RABiTS tapes

January 1, 2002
Author(s)
Najib Cheggour, John (Jack) W. Ekin, Cameron C. Clickner, Ron Feenstra, P Goyal, D F. Paranthaman, D F. Lee, D M. Kroeger, D. K. Christen
The electromechanical properties of (0.3 υm thick) yttrium-barium-copper-oxide (YBCO) coatings on buffered pure-nickel rolling-assisted-biaxially-textured substrates (RABiTS) were measured at 76 K and self magnetic field. YBCO coatings on buffered

Trapped Highly Charged Ion Plasmas

January 1, 2002
Author(s)
E Takacs, John D. Gillaspy
Electron beam Ion Trap (EBIT) devices are reviewed with special attention to applications in highly charged ion plasma research. EBIT properties are presented based on information extracted from a variety of experiments presented in the literature. Topics
