Fractured Practices: How Schooling Norms Limit Modeling Practices in Traditional Technical Thermal-Fluids Engineering Courses -- And the Possibilities Emerging through the Cracks
In professional science and engineering contexts, modeling practices are frequent and diverse. To understand, analyze, and communicate, scientists and engineers simplify and distort the complex systems with which they work. This practice is known as modeling. Typically, scientists create models to …

Minimizing uncertainty in cure modeling for composites manufacturing
… part forming process, as is the case for process modeling. The goals of this work are to identify sources of uncertainty in the decision-making process from cure measurement by differential scanning calorimeter (DSC) to cure kinetics modeling, and to recommend practices for reducing uncertainty. …

When Physics Became Undisciplined An Essay on Econophysics
… between such use of analogy in econophysics and modeling practices implemented by financial economics explains why econophysics remains so controversial to economists.

Cell phone location data for travel behavior analysis
… this data into existing urban and transportation modeling frameworks. In this thesis, we draw on techniques from the transportation engineering and urban computing communities to estimate travel demand and infrastructure usage. The methods we present utilize call detail records (CDRs) from mobile …

Discrete element modeling of railroad ballast using imaging based aggregate morphology characterization
… remain unknown. In previous designs and modeling practices, railroad ballast has usually been treated as a homogeneous and continuous layer. This approach is not suitable to model the deformation behavior of the particulate nature railroad ballast aggregates under dynamic moving loads. …

Effects of delayed drainage on subsidence modeling and parameter estimation
The use of delayed drainage in land subsidence modeling greatly complicates model calibration, particularly when the thickness of the fine-grained interbeds varies throughout the modeled region. This thesis documents two separate projects (chapters) related to the use of delayed drainage in …

Mechanistic modeling of alpha-synuclein aggregation and brain pharmacokinetics for drug development in neurodegeneration
Mechanistic modeling plays an increasingly important role in central nervous system (CNS) drug development, but its impact depends on how well models reflect the underlying biology and account for the limitations of available data. This thesis addresses these challenges through two distinct yet …
