Hardware Write Block (HWB) Specification Version 2.0

May 1, 2004
Author(s)
None
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

High-Resolution Optical Overlay Metrology

May 1, 2004
Author(s)
Richard M. Silver, Ravikiran Attota, M R. Bishop, Jay S. Jun, Egon Marx, M P. Davidson, Robert D. Larrabee
Optical methods are often thought to lose their effectiveness as a metrology tool beyond the Rayleigh criterion. However, using advanced modeling methods, the conventional resolution limitations encountered in well-defined edge-to-edge measurements using

HL7 Draft Electronic Health Record Conformance White Paper

May 1, 2004
Author(s)
Lynne S. Rosenthal, Gordon E. Lyon
The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance. It

Importance of Excluded Volume on the Solvation of Urea in Water

May 1, 2004
Author(s)
Raymond D. Mountain, D Thirumalai
We have used molecular dynamics simulations to probe the concentration-dependent solvation of urea in water. Two models of urea re considered: one of the in the OPLS potential and the other is the recently introduced KBFF model whose parameters were

Improving the Uncertainty of Photomask Linewidth Measurements

May 1, 2004
Author(s)
J Pedulla, James E. Potzick, Richard M. Silver
The National Institute of Standards and Technology (NIST) is currently developing a photomask linewidth standard (SRM 2059) with a lower expected uncertainty of calibration than the previous NIST standards (SRMs 473, 475, 476). In calibrating these

Influence of Heating Rate on Flow Stress in High-Speed Machining Processes

May 1, 2004
Author(s)
Matthew A. Davies, Sean W. Smith
For several decades, a major focus of machining research has been the measurement and prediction of temperature. Here, the influence of the rate of heating on the flow processes, in particular to predictions of the temperature, are discussed. Results are

Long-Term Strength of Ceramics for Biomedical Applications

May 1, 2004
Author(s)
Yu Zhang, Brian R. Lawn
The influence of slow crack growth on the initiation of radial cracks at the undersurfaces of ceramic layers on polymeric substrates is studied, with particular relevance to biomechanical systems dental crowns and hip replacement prostheses. Critical loads

MEMS Sensors for HVAC&R

May 1, 2004
Author(s)
David A. Yashar, Piotr A. Domanski
MicroElectronic Mechanical Systems (MEMS) have revolutionized the market for sensors by providing small, fast-responding measurement devices at very low cost. These measurement devices have been widely accepted in many areas of engineering and have vastly

Multiscale Modeling of Mechanical Response of Quantum Nanostructures

May 1, 2004
Author(s)
Vinod K. Tewary, B Yang
A multiscale Green's function method is described for modeling the mechanical response of quantum nanostructures in semiconductors. The method accounts for the discreteness of the lattice in and around the nanostructure, and uses the continuum Green's

Non-contact Electrical CD Metrology Sensor for Chrome Photomasks Featuring a Low Temperature Co-fired Ceramic Technology

May 1, 2004
Author(s)
Nadine Guillaume, Richard A. Allen, Michael W. Cresswell, Markku Lahti, Loren W. Linholm, Mona E. Zaghloul
The paper describes a non-contact capacitive-sensor metrology sensor developed to measure minimum feature sizes, also called critical dimensions (CDs), patterned on photomasks that are used in semiconductor device manufacture. Additionally, this paper

Observation of a geometrically constrained domain wall in epitaxial FCC Co small disks

May 1, 2004
Author(s)
C Vaz, L Lopez-Diaz, M Klaui, J Bland, T Monchesky, John Unguris, Z Cui
The magnetic nanostructure of epitaxial FCC Co/Cu(0 0 1) circular elements (1.7 m in diameter) has been imaged with scanning electron microscopy with polarization analysis. A closed flux configuration (quadrant configuration) is observed for most of the

Optical Coherence Microscopy for in-situ Monitoring of Cell Growth in Scaffold Constructs

May 1, 2004
Author(s)
Marcus T. Cicerone, Joy Dunkers, N. R. Washburn, Forrest A. Landis, James A. Cooper
Tissue scaffold morphological properties are determined and correlated with osteoblast proliferation and ingrowth. Scaffold pore size and connectivity were characterized with x-ray tomography. Cell proliferation and ingrowth were measured with confocal
