A General Modeling Framework for Cost Benefit Analysis of Remanufacturing
… we considered “remanufacturing” and developed a modeling framework for its cost benefit analysis. Our modeling framework focuses on the profitability of remanufacturing as it is a key motivating factor for remanufacturing the used product.<p>This modeling framework consists of three phases: take …

Quantifying the Effect of Disease Characteristics on the Outcomes of Interventions Using Mathematical Modelling
… the COVID-19 pandemic. This thesis presents a general modeling framework for the transmission dynamics of influenza and SARS-CoV2, examining the impact of their characteristics on intervention outcomes. Simulations and sensitivity analysis show that the length and infectiousness profile during …

Modeling, simulation, and control design of electro-mechanical dynamics in heterogeneous power systems
In this thesis, a general modeling framework to study power systems with synchronous generators and grid forming inverters with droop control, virtual synchronous machine control, and dispatchable virtual oscillator control is developed. To mitigate model complexity and facilitate analytical …

Implementing a cognitive diagnostic assessment in an institutional test: a new networking model in language testing and experiment with a new psychometric model and task type
… compared for language test data under a unified general modeling framework. The models are applied to three sets of data, TOEFL Reading, TOEFL Listening and ECPE Grammar and examined in terms of their model fit to the data and functioning. The item-association root mean squared error values and …

Dynamic model for space-time weather radar observation and nowcasting
A general framework of the dynamic model for space-time radar observations has been developed in the current research. There exist three difficulties in modeling spacetime radar observations: 1) high dimensionality due to the high-resolution radar measurements over a large area, 2) non-stationarity …

A unified methodology of maintenance management for repairable systems based on optimal stopping theory
… research is to develop a unified methodology for modeling and optimization of maintenance systems. A general modeling framework with six classifying criteria is to be developed to formulate and analyze a wide range of maintenance systems which include many existing models in the literature. A …

Geometric modeling and analysis of dynamic resource allocation mechanisms
… It is presented as a specific case of a more general modeling framework we put forth. The underlying question asks how to partition a given resource into a fixed number of parts such that the elements of the resulting partition can be scheduled among a set of user requests to minimize the …

Influences of Mountainside Residential Development to Nutrient Dynamics in a Stream Network
… hydrology in hillslope soils. With this complete modeling framework, I conducted a global sensitivity analysis to evaluate the importance of terrestrial nutrient input versus in-stream processes in modifying nitrogen export. I also conducted a simulation to investigate the impacts of housing …

Mathematics, Methods, and Models for Data-Driven Rheology
… rheology. Based on a polynomial expansion of the general time-invariant functional relationship between shear stress and strain (or strain rate) in simple shear flows, MAPS reveals a common embedding for many previously disconnected data sets. This asymptotic framework enables direct comparisons …
