Motivated by the rich variety of complex patterns observed on the surface of fluid layers that are vibrated at multiple frequencies, we investigate the effect of such resonant forcing on systems undergoing a Hopf bifurcation to spatially homogeneous oscillations. We use an extension of the complex Ginzburg-Landau equation (CGLE) that...
Stochastic programming models static or dynamic optimal decision making under uncertainty. In contrast to deterministic mathematical programming, stochastic programming generally uses expectation functionals in objective or constraints over known or partially known distributions of the problem data. Its features many decision variables under complicated constraints over discrete time periods. Its...
The overall objective of this thesis is to develop a package of high-resolution, non-invasive experimental and numerical approaches to observe in situ pore-scale geometry modification due to colloid deposition, and quantitatively predict its effects on the large-scale transport properties of the porous medium. High-energy synchrotron-based X-ray difference micro-tomography (XDMT) was...
This dissertation contains three essays that investigate various factors affecting firms' choice of quality in the context of nursing homes.
The first essay examines how strategic interactions with competitors affect quality levels selected by nursing homes. I explore nursing homes' responses to minimum nurse staffing standards imposed in two large...
The present thesis presents a new application of dynamic constructivism (Hong, Morris, Chui, & Benet-Martinez, 2000; Morris & Fu, 2001) to teamwork process in creativity in multicultural teams. With its roots in cognitive psychology, dynamic constructivist theory posits that varying values, social structures, and norms within cultures create different knowledge...
>"Surprising Metamorphoses: Transformations of Race in Early American Literatures," analyzes early American literary representations of race within the context of contemporaneous belief systems. Contrasting sharply with subsequent periods, much late eighteenth-century thought conceptualized race as an external, mutable bodily condition that could change over time. Identifying how this thinking informs...
In this work, electron beam induced current (EBIC) and scanning photocurrent microscopy (SPCM) were used to quantitatively investigate the electronic properties of silicon nanowire devices. For the first time, it was shown that minority carrier diffusion lengths in phosphorous-doped silicon nanowires are significantly reduced from their bulk values because of...
This dissertation is composed of three chapters, each contributing to different aspects of the literature of partially identified econometric models.
In the first chapter, I introduce a bootstrap procedure to perform inference in the class of partially identified econometric models defined by finitely many moment equalities and inequalities. I provide...
Increasing interest in long-life bone implants with reduced mechanical properties reducing the stress-shielding effect and a structure mimicking bone porous architecture has encouraged study and development of fabrication methods for porous NiTi. The main objective of this work was to advance these goals by developing new processing procedures for porous...
Several surface wave tomographic studies of the upper mantle structure beneath North America are presented, which take advantage of high quality seismic data, primarily recorded in the last decade, to create better resolved S-wave tomographic models. The first study presents a regional 3D model, IL05, of the upper mantle beneath...
