Halide perovskites, AMX3 (A = monocation, B = Ge, Sn, or Pb, and X = halogen), present a versatile class of solution-processable semiconductors made from earth abundant materials with outstanding electrical and optical properties. Their solar cell efficiencies have dramatically increased from ~9% to ~22% in less than five years...
Circling the Cosmograms marks the first full-length study of second-generation feminist and/or queer art and performance in the Haitian Dyaspora (Haitian Kreyòl spelling) following the January 12, 2010 earthquake in Haiti. Through archival research, visual and performance art analysis, and in-depth interviews, I document the ways feminist and/or queer Haitian-American...
Accurate thermodynamic databases are the foundation of predictive microstructure and property models. An initial assessment of the commercially available Thermo-Calc TCAL2 database and the proprietary aluminum database of QuesTek demonstrated a large degree of deviation with respect to equilibrium precipitate phase prediction in the compositional region of interest when compared...
Free radical polymerization has a wide range of applications and continues to attract research interest as the demand for tailored specialty polymers grows. Sequence distribution, tacticity and composition of copolymers play a key role in understanding the reaction kinetics and the properties of the polymers 1. One of the chief...
Thermal overheating is a serious concern in modern supercomputing systems. Elevated temperature levels reduce the reliability and the lifetime of the underlying hardware and increase their power consumption. Previous studies on mitigating thermal hotspots at the hardware and run-time system levels have typically used approaches that trade off performance for...
Spatial-temporal data mining, with data driven model and machine learning techniques, significantly benefit the traditional transportation research. This dissertation focus on three problems related to uncertain location data, lane-level traffic speed clustering and anomalous traffic speed prediction.
We take a first step towards combining the uncertain location data i.e., fusing...
This dissertation explores the relationship between dance cultures and media cultures in the United States between the 1940s and the 1960s, when both were experiencing a period of multiplicity and flux in their forms. Bringing together theories and methodologies from dance studies, media studies, and cultural history, it considers how...
In this thesis, we advocate for the use of slice spheres, a common generalization of representation spheres and induced spheres, in parameterized homotopy theory. First, we give an algebraic characterization of the layers of the Hill-Hopkins-Ravenel slice filtration.
Next, we explore the homology of parameterized symmetric powers from this point...
The floor plate (FP) is a ventral midline organizing structure of the developing neural tube that provides positional information using morphogen concentration gradients towards the production of diverse neuron types. In caudal regions the FP is non-neurogenic unlike the mesodiencephalic region of the FP that is highly neurogenic, and is...
Traditionally, simulation analysis has focused on designing a computationally efficient algorithm assuming a correct simulation model is given. As computation becomes cheaper, we are now able to perform more sophisticated simulation analyses involving extensive computation and consider all sources of errors in the simulation model and their effects to the...
