The goal of this research was to develop the understanding of the structure/property relations in Y{sub 2}O{sub 3}-stabilized cubic ZrO{sub 2} (Y-CSZ) single crystals with emphasis on the potential use of these materials as a fibrous reinforcement for high temperature structural applications. In particular, the issues addressed include: (i) determination of the structure of as-grown Y-CSZ and its relation to the deformation behavior and (ii) initial fiber growth and evaluation. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

The Boussinesq system describes weakly nonlinear dispersive long waves plasmas and incompressible irrotational fluids. This study presents some results regarding the structure and behavior of a system of equations that yield the spatial structure of triad interactions in the Boussinesq system. Such a system forms part of a model for the formation and evolution of sand ridges on the continental shelf. The aims of this study are to provide some insight into the behavior of the triad system and into the sand ridge model in particular.
