Effects of Wafer Emissivity on Rapid Thermal Processing Temperature Measurement

September 1, 2002
Author(s)
D H. Chen, D P. DeWitt, Benjamin K. Tsai, Kenneth G. Kreider, William A. Kimes
Lightpipe radiation thermometers (LPRTs) are widely used to measure wafer temperatures in rapid thermal processing (RTP) tools. Using blackbody-calibrated LPRTs to infer the wafer temperature, it is necessary to build a model to predict the effective

Electron Drift in C4F6 and C4F6/Ar Mixtures

September 1, 2002
Author(s)
Amanda N. Goyettes, Yicheng Wang, Gerald FitzPatrick
We report measurements of electron drift velocities as a function of density-reduced electric field, w(E/N), for hexafluorobutadiene (C4F6) and mixtures of C4F6 with Ar. The w(E/N) for the mixtures of C4F6 with Ar can aid Boltzmann transport equation

Enclosure Effects on Flame Spread Over Solid Fuels in Microgravity

September 1, 2002
Author(s)
Y N. Nakamura, Takashi Kashiwagi, Kevin B. McGrattan
Enclosure effects on the transition from localized ignition to subsequent flame spread over a thermally-thin solid fuel in microgravity are investigated numerically solving the low Mach number time-dependent Navier-Stokes equations. The numerical model

Experiences with Point Cloud Registration

September 1, 2002
Author(s)
Christoph J. Witzgall, Geraldine Cheok
The development of LADAR (laser distance and ranging) technology to acquire 3D spatial data made it possible to create 3D models of complex objects. Because an unobstructed line-of-sight is required to capture a point on an object, an individual LADAR scan

Finite Element Simulation of Straight Plunge Grinding for Advanced Ceramics

September 1, 2002
Author(s)
Tze J. Chuang, S Jahanmir, Hai C. Tang
The objective of this work is to model the grinding forces and the associated stress and deformation fields generated in a ceramic workpiece during surface plunge grinding. A two-dimensional finite element model is constructed with the grinding parameters

Four-state measurement method for polarization dependent wavelength shift

September 1, 2002
Author(s)
William C. Swann, Shellee D. Dyer, Rex M. Craig
We present a novel four-state method for measuring the polarization dependent wavelength shift (PDW) of a fiber Bragg grating. We show that measurement of the grating's wavelength for only four different polarization states is sufficient to completely

Healthcare Information Standards & Testing: A Concept Paper

September 1, 2002
Author(s)
Lisa J. Carnahan, Lynne S. Rosenthal
This paper was inspired by preliminary discussions between NIST and members of the healthcare community who are impacted by the use of emerging information technology. Topics of discussion included the current state of standards work in the healthcare

Helical, Disordered, and What that Means: Structural Characterization of a New Series of Methyl 1-Thiaoligo(Ethylene Oxide) Self-Assembled Monolayers

September 1, 2002
Author(s)
David J. Vanderah, J Arsenault, H La, Vitalii I. Silin, Curtis W. Meuse, Richard S. Gates
Self-assembled monolayers (SAMs) of a series of linear thiols containing a 1-thiaoligo(ethylene oxide) [TOEO] moiety, i.e., HS(CH2CH2O)xCH3, where x = 3 - 6, were prepared on polycrystalline gold (Au) and characterized by reflection adsorption infrared

In Situ Raman Spectroscopic Investigation of Stainless Steel Hydrothermal Corrosion

September 1, 2002
Author(s)
James E. Maslar, Wilbur S. Hurst, Walter J. Bowers Jr., Jay H. Hendricks
In situ Raman spectroscopy was employed to investigate corrosion of 304L stainless steel in air-saturated water at a pressure of 25.2 Mpa and temperatures up to 496 C in an optically accessible flow cell. The steel also was characterized ex situ with Raman

Influence of Solvent on Dynamics and Stability of a Protein

September 1, 2002
Author(s)
G Caliskan, A Kisliuk, A M. Tsai, Christopher Soles, Alexei Sokolov
Proteins are often dissolved in viscous glass-forming solvents to provide thermal stability and preserve biochemical activity. However, the mechanisms by which this preservation is achieved are unclear. This issue of biopreservation is undoubtedly affected

Information Access: Do You Mind?

September 1, 2002
Author(s)
John V. Cugini
Successful execution of many information-based tasks depends crucially on contextual knowledge. Language processing is particularly sensitive to context, and I will concentrate on it in this extended abstract as the example par excellence of knowledge

Interface-Driven Model-Based Generation of Java Test Drivers

September 1, 2002
Author(s)
Mark Blackburn, Robert Busser, Aaron Nauman, Ramaswamy Chandramouli
This paper extends prior work in model-based verification and describes interface-driven analysis that combines with a requirement model to support automated generation of Java test scripts. It describes concepts of models and test driver mappings using

Kinetic Minimum-Power Routing and Clustering in Mobile Ad-Hoc Networks

September 1, 2002
Author(s)
Camillo Gentile, R E. Van Dyck, J Haerri
We have previously developed a distributed routing algorithm which minimizes the number of overhead messages necessary to maintain the minimum-power multi-hop routes in a mobile ad-hoc network, assuming a piece-wise linear model for the motion of the nodes

Knowledge Engineering for Real-Time Intelligent Control

September 1, 2002
Author(s)
John Evans, Elena R. Messina, James S. Albus, Craig I. Schlenoff
The key to real-time intelligent control lies in the knowledge models that the system contains. Three main classes of knowledge are identified: parametric, geometric/iconic, and symbolic. Each of these classes provides unique perspectives and advantages

Magnetic Properties of Ultrathin Laminated Co/Cu Films Prepared by Electrodeposition

September 1, 2002
Author(s)
M Shima, L Salamanca-Riba, Thomas P. Moffat, Robert D. McMichael
The magnetic properties of a series of electrodeposited [Co(x ML)/Cu(17 ML)]100 multilayers have been examined as a function of the cobalt layer thickness. The multilayers were grown on Si(100)covered with a highly textured Cu(100) seed alyer. Films with a
