Some Difficult Problems in the Modeling of Fire Spread

July 16, 2006
Author(s)
Kathryn M. Butler, Thomas J. Ohlemiller
A fire and the objects involved in the fire form a highly complex dynamic system. Important processes occur over a wide range of spatial and temporal scales, from the microscales of thermodynamics and chemical kinetics, through the mesoscales of heat

Nano-Tip Electron Gun for the Scanning Electron Microscope

January 1, 2006
Author(s)
Andras Vladar, Zsolt Radi, Michael T. Postek, David C. Joy
Through this study the most important questions and problems associated with nano-tips and their possible applications to SEMs were investigated. These were related to the tip making procedures, the theoretical assessment of the Hitachi S-6000 critical

Topography Measurements and Applications

January 1, 2006
Author(s)
Jun-Feng Song, Theodore V. Vorburger
Based on auto- and cross-correlation functions (ACF and CCF), a new surface parameter called profile (or topography) difference, Ds, has been developed for quantifying differences between 2D profiles or between 3D topographies with a single number. When Ds

Statistical Aspects of Linkage Analysis in Interlaboratory Studies

November 9, 2005
Author(s)
W Strawderman, Andrew L. Rukhin
This paper investigates issues that arise in statistical inference in interlaboratory studies known as Key Comparisons when one has to link several comparisons to or through existing studies. A new approach to the analysis of such a data is proposed using

The Rotational Spectrum of the Ground State of Methylamine

February 1, 2005
Author(s)
Vadim V. Ilyushin, E A. Alekseev, S F. Dyubkoa, R A. Motiyenkoa, Jon T. Hougen
Recent progress is reported in measuring, assigning and fitting the rotational spectrum of the ground vibrational state of methylamine, CH3NH2, a spectrum complicated both by internal rotation of the methyl top and by inversion of the amino group. New
