Investigation of BARC-Resist Interfacial Interactions

June 1, 2003
Author(s)
C Devadoss, Yijun Wang, R Puligadda, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, E Jablonski, Daniel A. Fischer, S Sambasivan, Eric K. Lin, Wen-Li Wu
Results are reported from studies of (A) surface versus bulk chemistry of BARC materials as a function of cure temperature, (B) the dependence of the thickness and composition of the residual layer (resist material remaining on the surface of the BARC

Isotopic Metrology of Carbon Dioxide. I. Interlaboratory Comparison and Empirical Modeling of Inlet Equilibration Time, Inlet Pressure, and Ion Source Conductance

June 1, 2003
Author(s)
R M. Verkouteren, C E. Allison, S A. Studley, K J. Leckrone
We report a pilot study of high-precision differential isotopic ratio measurements made on replicate samples of pure carbon dioxide using three instruments of identical manufacture. Measurement protocols were designed to explore the effects of sample size

Iterative Registration of 3D LADAR Data for Autonomous Navigation

June 1, 2003
Author(s)
Rajmohan Madhavan, Elena R. Messina
This paper describes an iterative algorithm for registration of 3D LADAR data. The proposed approach is iconic in nature with suitable modifications to deal with false/spurious matches, occlusions and outliers. Experimental results using data obtained from

Kinetic Pathway of the Bilayered-Micelle to Perforated-Lamellae Transition

June 1, 2003
Author(s)
Haonan Wang, M P. Nieh, Erik K. Hobbie, Charles J. Glinka, J Katsaras
Near-edge x-ray absorption fine structure (NEXAFS) spectroscopy was used to meausre simultaneously the relaxation rates of polystyrene (PS) molecules at the free surface and in the bulk. The samples were uniaxially stretched and annealed at temperatures

Kolsky Bar With Electrical Pulse Heating of the Sample

June 1, 2003
Author(s)
Eric P. Whitenton, Michael Kennedy, Matthew A. Davies, Gerald V. Blessing, Brian S. Dutterer, Richard L. Rhorer, Howard W. Yoon, Lyle E. Levine, Richard J. Fields, D Basak, Timothy J. Burns
The accuracy of simulations for modeling of machining processes is often limited due to insufficient knowledge of the material properties during machining, which can involve strain rates on the order of 104 per second or higher, plus rapid material heating

Localized Ferromagnetic Resonance in Inhomogeneous Thin Films

June 1, 2003
Author(s)
Robert McMichael, A Kunz, D J. Twisselmann
The effect of sample inhomogeneity on the ferromagnetic resonance line width is determined by diagonalization of a spin wave Hamiltonian for ferromagnetic thin films with inhomogeneities. The resonance line broadening results from the distribution of the

Micro Channel Heat Transfer, Pressure Drop and Macro Prediction Methods

June 1, 2003
Author(s)
Mark A. Kedzierski
Advances in the basic understanding of fluid physics have opened an era of unprecedented application of heat transfer processes, and fluid dynamics systems using micro channels. One of the greatest obstacles to the application of leading edge fluid physics

Microwave Surface Impedance and Nonlinear Properties of MgB 2 Films

June 1, 2003
Author(s)
James Booth, Sang Y. Lee, Kenneth Leong, J. H. Lee, J. Lim, H. N. Lee, S. H. Moon, B. Oh
We have measured the temperature dependence of the microwave surface impedance and the nonlinear response of high-quality MgB 2 films on c-cut sapphire at temperatures below 40 K. MgB 2 films with surface resistance (Rs) as low as 0.09 mOhm} at 8 K and 19

MOBY, A Radiometric Buoy for Performance Monitoring and Vicarious Calibration of Satellite Ocean Color Sensors: Measurement and Data Analysis Protocols

June 1, 2003
Author(s)
D K. Clark, Marilyn Y. Murphy, M Yarbrough, M Feinholz, S Flora, W Broenkow, B. Carol Johnson, Steven W. Brown, Y S. Kim, J Mueller
The Marine Optical Buoy (MOBY) (Clark et al. 1997) is the centerpiece of the primary ocean measurement site for calibration of satellite ocean color sensors based on independent in situ measurements. Since late 1996, the time series of normalized water

NIST Research Library Benchmark Study, 2001: Summary Report

June 1, 2003
Author(s)
P J. Deutsch, Diane Cunningham, L A. Greenhouse, Susan L. Makar, W F. Overman, Susan A. Sanders, Barbara P. Silcox
In 2002, the NIST Research Library of the Information Services Division, Technology Services, benchmarked itself against other science and technology libraries. These libraries had similar focus areas and were comparable in size. The study compared library

NIST/SEMATECH Engineering Statistics Handbook Chapter 8: Reliability

June 1, 2003
Author(s)
Alan Smeaton
In today's technological world nearly everyone depends upon the continued functioning of a wide array of complex machinery and equipment for their everyday health, safety, mobility and economic welfare. Continual assessment of product reliability, and on

Observation of Photons Emitted During Inhibited Spontaneous Emission

June 1, 2003
Author(s)
D A. Branning, P G. Kwiat, Alan L. Migdall
We present the results of an experiment to observe inhibited spontaneous emission of a parametric downconverter by an optical cavity whose switching time is short compared with the round trip time of the light. The question is, can photons be counted

Obtaining Spectral Data for Colorimetry

June 1, 2003
Author(s)
Yoshihiro Ohno
Simulation analyses have been conducted on the colorimetric errors associated with the data interval, bandpass, and wavelength errors of a spectrometer, using spectral data of 43 object color samples including those from CIE 13.3, BCRA tiles, and the

Performance of 32-channel Time-Division SQUID Multiplexer for Cryogenic Detector Arrays

June 1, 2003
Author(s)
Joern Beyer, Piet DeKorte, Carl D. Reintsema, Sae Woo Nam, Gene C. Hilton, Leila R. Vale, Kent D. Irwin
Multiplexed readout is a practical requirement for the successful deployment of large-scale cryogenic detector arrays in applications ranging from x-ray microanalysis to sub-millimeter astronomy. We report on the development of a time-division SQUID

Performance of Service-Discovery Architectures in Response to Node Failures

June 1, 2003
Author(s)
Christopher E. Dabrowski, Kevin L. Mills, Andrew L. Rukhin
Current trends suggest future software systems will rely on service-discovery protocols to combine and recombine distributed services dynamically in reaction to changing conditions. We investigate the ability of selected designs for service-discovery

Precision Wavelength Metrology with a Fourier Transform Spectrometer

June 1, 2003
Author(s)
D. Veza, Marc L. Salit, John C. Travis, Craig J. Sansonetti
We have investigated the intrinsic accuracy of the optical frequency scale in spectra acquired by a Fourier Transform Spectrometer (FTS). The uncalibrated accuracy of the FTS optical frequency axis is about 1 part in 10 5. This uncertainty can be reduced
