Let X be a quasi-projective complex variety. It follows from the work of Voevodsky that the motivic cohomology of X, denoted as $H^{p,q}(X)$ where q and p are integers with q nonnegative, can be represented in the triangulated category of motives over the field of complex numbers, denoted as $DM^{eff,-}_{Nis}$....
Time-resolved in situ synchrotron x-ray scattering studies of particle orientation in polymer-clay nanocomposites under simple shear and complex flow were performed. Shear flow experiments used an annular cone and plate x-ray shear cell to allow measurement of platelet orientation within the flow-gradient plane.
Intercalated nanocomposites were made by dispersing organically...
Chapter one investigates the impact of agents' expectations about future fundamental economic disturbances (news) on macroeconomic dynamics. Several intuitive tests provide insight into the information content of the yield curve and its' ability to identify these 'news' disturbances. Bayesian estimation of a dynamic stochastic general equilibrium (DSGE) model using conventional...
The kinetoplastid protozoan <em>Trypanosoma brucei</em> is the causative agent of African trypanosomiasis, affecting humans, and Nagana disease, affecting cattle, prevalent in regions of sub-Saharan Africa. Our lab demonstrated that the flagellum of <em>T. brucei</em> is enriched in lipid rafts, membrane areas composed of sphingolipids, sterols, and proteins that serve as...
Two main topics are addressed in this dissertation: (1) adhesion in hydrogels; (2) interfacial interactions between model glassy polymers. A self-assembly technique for the formation of hydrogels from acrylic triblock copolymer solutions was developed, based on vapor phase solvent exchange. Structure formation in the gels was characterized by small angle...
This dissertation considers price indices in the context of two rapidly growing markets. The first is the emerging market for Internet Service Providers in the mid-1990s. The second is the emergence and growth of the DVD hardware market. In both, we examine indices ranging from the most rudimentary to quality...
"Prufrock" to <em>The Waste Land</em>: T. S. Eliot's Periodical Publications, 1915-1922 Randall J. Woods This dissertation presents, in publication date order, the 167 articles published by T. S. Eliot from 1915 to 1922, most of which have never been reprinted. They include literary criticism, book reviews, poetry, philosophical essays, humorous...
The purpose of this dissertation study was to build on scholarly work in the area of critical mathematics by such scholars as Gutstein (2003) and Gutierrez (2002). Critical pedagogy is designed to foster political agency and critical consciousness in students (Freire, 1971). That is the aim of critical mathematics in...
Three critical problem areas pertinent to the development of precision high-speed spindles for meso-scale machine tools (mMTs), driven by air turbines, constitute the focus of this work. These are the development of the spindle, of a new tool clamping device, and of a measurement system for spindle error motions.
For...
Biomorphic silicon carbide (bioSiC) is a novel porous ceramic material derived directly from wood precursors. This material is fabricated by pyrolysis of a natural wood precursor in an inert atmosphere leaving an amorphous carbon scaffold. The amorphous carbon is infiltrated with molten Si in vacuum at elevated temperature, which reacts...
