Optimization Of Dynamic Objective Functions Using Path Integrals, Paramahansa Pramanik
Optimization Of Dynamic Objective Functions Using Path Integrals, Paramahansa Pramanik
Graduate Research Theses & Dissertations
Path integrals are used to find an optimal strategy for a firm under a Walrasian system. We define dynamic optimal strategies and develop an integration method to capture all non-additive non-convex strategies. We also show that the method can solve the non-linear case, for example Merton-Garman-Hamiltonian system, which the traditional Pontryagin maximum principle cannot solve in closed form. Furthermore, we assume that the strategy space and time are inseparable with respect to a contract. Under this assumption we show that the strategy spacetime is a dynamic curved Liouville-like 2-brane quantum gravity surface under asymmetric information and that traditional Euclidean geometry …
Clinical Applications And Feasibility Of Proton Ct And Proton Radiography, Christina Marie Sarosiek
Clinical Applications And Feasibility Of Proton Ct And Proton Radiography, Christina Marie Sarosiek
Graduate Research Theses & Dissertations
Proton therapy is a form of radiation treatment for cancer that utilizes the Bragg peak to create conformal high dose regions around the tumor volume. However, the use of x-ray computed tomography (CT) and x-ray radiography for treatment planning and pre-treatment quality assurance procedures improves the achievable effectiveness of proton treatment plans (using proton CT) and the pretreatment verification (using proton radiography). Errors in the conversion from x-ray Hounsfield units (HU) to proton relative stopping powers (RSP) leads to errors in the predicted proton range. To account for the errors, 3.5% margins are included in the treatment plan. This means …
Pumping Fees And Spillovers In The Groundwater Commons: An Evaluation Of A Conservation Tool And Irrigator Competitive Behavior, Godwin Kwabla Ekpe
Pumping Fees And Spillovers In The Groundwater Commons: An Evaluation Of A Conservation Tool And Irrigator Competitive Behavior, Godwin Kwabla Ekpe
Graduate Research Theses & Dissertations
My dissertation examines the effectiveness of pumping fees in groundwater commons agricultural irrigation as a conservation tool in the presence of varying water scarcity levels and spatial interdependence among irrigators. The first chapter provides a brief overview of three important areas of groundwater commons irrigation addressed in this dissertation. The second chapter’s objectives are two-fold. First, I review the common-pool resources literature relative to concerns of sustainable extraction and implementation of conservation policies focusing on pricing incentives in the management of groundwater commons where irrigators share the same underlying aquifer. Second, I introduce a theoretical model involving incorporating a non-constant …
A "Warm" Or "Cold" Early Mars: Evidence From Valley Networks, Xuezhi Cang
A "Warm" Or "Cold" Early Mars: Evidence From Valley Networks, Xuezhi Cang
Graduate Research Theses & Dissertations
Although Mars is cold and dry today, many lines of evidence suggest that ancient Mars had large amount of water and surface fluvial processes. However, climate modelers have encountered difficulties in modeling such early warm and wet conditions with an above freezing temperature, mainly due to the Martian orbit being further away from the Sun and the faintness of the young Sun. The main purpose of this dissertation is to test the ancient Martian climate hypotheses by investigating the spatial pattern of valley network (VN) properties that can survive post-formational modification (i.e., the robust characteristics) and by analogizing the Earth …
The Relevance Of Credit Risk In The Determination Of Commercial Banks’ Profitability: Evidence From Ghana, Godwin Kwabla Ekpe
The Relevance Of Credit Risk In The Determination Of Commercial Banks’ Profitability: Evidence From Ghana, Godwin Kwabla Ekpe
Graduate Research Theses & Dissertations
Existing empirical literature on the relationship between credit risk and bank’s profitability is replete with mixed results. This research investigates the probable effect of credit risk on banks’ profitability by examining the nature of the relationship between two measures of credit risk (Loss provisioning rate and Actual provisioning charge rate) and two measures ofprofitability (Return on assets and Return on Equity). The investigation is conducted using data on the Ghanaian banking industry. Various modeling techniques are used to fit the data, including frequentist beta regression and Bayesian beta regression models. The results across all models suggest negative linear relationship between …
