UML Model for the IEEE 1451.1 Standard

January 1, 2003
Author(s)
Kang B. Lee, Yuyin Song
The IEEE 1451.1 Standard for Smart Transducer Interface for Sensors and Actuators- Network Capable Application Processor (NCAP) Information Model was established to define a common objective model and interface specification for the components of a

Uncertainty Budgets for Realization of ITS-90 by Radiation Thermometry

January 1, 2003
Author(s)
J Fischer, M Battuello, M Sadli, M Ballico, S N. Park, P Saunders, Y Zundong, B. Carol Johnson, E Van der Ham, F Sakuma, Graham Machin, N Fox, W Li, S Ugur, M Matveyev
Recent international comparisons [1,2] and key comparisons have shown that the realization of the ITS-90 above the freezing point of silver and its dissemination may be less straightforward than expected. In many cases, the deviations of the local scale

Updated NIST Photomask Linewidth Standard

January 1, 2003
Author(s)
James E. Potzick, J Pedulla, Michael T. Stocker
NIST is preparing to issue the next generation in its line of binary photomask linewidth standards. Called SRM 2059, it was developed for calibrating microscopes used to measure linewidths on photomasks, and consists of antireflecting chrome line and space

Wall Migration and Shear-Induced Diffusion of Fluid Droplets in Emulsions

January 1, 2003
Author(s)
Steven D. Hudson
The spatial distribution of drops in multiphase flow through narrow passages is analyzed theoretically and experimentally. In simple shear between two plates, drops migrate away from the walls and concentrate towards the center of the gap. At steady state

Wavelength-Shift and Fluorescent Probes for Cure Monitoring of Resins

January 1, 2003
Author(s)
Francis W. Wang, R E. Lowry
The peak frequencies of the absorption and fluorescence spectra of some fluorescent probes dissolved in resins are sensitive ton the polarity and the local viscosity. The peak absorption and fluorescence frequencies of wavelength-shift fluorescent probes

Wear in Boundary Lubrication

January 1, 2003
Author(s)
Stephen M. Hsu, R G. Munro, M C. Shen
Wear studies under lubricated conditions can be classified into two nominally distinct categories: investigations of thewear mechanisms active within the material, and studies of the degradation mechanisms active within the lubricant. Thetwo categories

Wear of Hydroxyapatite Sliding Against Glass-Infiltrated Alumina

January 1, 2003
Author(s)
Sergei Kalinin, B Hockey, S Jahanmir
The present work reports on the processes involved in the wear of hydroxyapatite sliding against slip-cast, glass-infiltrated alumina. Synthetic hydroxyapatite is used as a model material representing tooth enamel, while the alumina that was used is

Wear Transitions and Tribochemical Reactions in Ceramics

January 1, 2003
Author(s)
S Jahanmir
Structural ceramics are used in diverse tribological applications due to their unique properties that include resistance to abrasion and erosion, resistance to corrosive wear, wear resistance at elevated temperatures, low density, and unique electrical

Weibull Strength Scaling for Standardized Rectangular Flexure Specimens

January 1, 2003
Author(s)
George D. Quinn
Formulas for the effective volumes and effective surfaces for rectangular bars loaded in flexure are reviewed. The ratio of strengths from any two configurations, such as 3-point flexural to 4-point, is independent of whether the flaws are volume or
