Characterization of Composite Microstructure and Damage Using Optical Coherence Tomography

January 1, 1999
Author(s)
Joy Dunkers, C G. Zimba, Kathleen M. Flynn, Donald L. Hunston, R Prasankumar, X Li, J G. Fujimoto
Optical coherence tomography (OCT) is a non-destructive and non-contact technique that images microstructure within scattering media. In this work, the versatility of OCT for non-destructive evaluation is demonstrated through imaging of composite

Characterization of Ternary Compounds in the BaO:Fe 2 O 3 :TiO 2 System: Ba 6 Fe 45 Ti 17 O 106 and BaFe 11 Ti 3 O 23

January 1, 1999
Author(s)
Terrell A. Vanderah, Winnie K. Wong-Ng, B H. Toby, V. M. Browning, Robert D. Shull, Richard G. Geyer, Robert S. Roth
Single crystals of Ba 6Fe 45Ti 17O 106 and BaFe 11Ti 3O 23 were obtained as major and minor co-products, respectively, by slow-cooling an off-stoichiometric BaO:Fe 2O 3:TiO 2 melt. The former compound exhibits variable stoichiometry Ba 6Fe 48-xTi 14+xO 106

Comparison of Classical and MALDI-TOF-MS Analysis of a Polystyrene Interlaboratory Sample

January 1, 1999
Author(s)
William R. Blair, B M. Fanconi, R J. Goldschmidt, Charles M. Guttman, William E. Wallace, S Wetzel, David L. VanderHart
Over the past several years, the use of MALDI-TOF-MS for analysis of synthetic polymers has increased significantly. As the number of polymer analyses by MALDI has increased, scrutiny of the MALDI results in comparison to classically derived values for Mw

Comparisons of Control Charts for Autocorrelated Data

January 1, 1999
Author(s)
Nien F. Zhang
Recently, statistical process control (SPC) methodolgies have been developed to accommodate autocorrelated data. A primary method to deal with autocorrelated data is the use of residual charts. Although this methodology has the advantage that it can be

Computer Simulation and Percolation Theory Applied to Concrete.

January 1, 1999
Author(s)
Edward J. Garboczi, Dale P. Bentz
Concrete is a multilength scale composite material. From the nanometer to the millimeter scale, it is a random composite, and a different random composite at each length scale. Percolation processes play a key role in the microstucture of concrete, and
