Implementing The Heston Option Pricing Model In Object-Oriented Cython, Brandon Hardin

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The 1973 Black-Scholes model, a revolutionary option pricing formula whose price is 'relatively close to observed prices, makes an assumption that the volatility is constant and thus, deterministic. This causes some inefficiencies and patterns in the pricing of options due to the model providing evidence of the volatility smile' of the volatility. Many scholars have suggested that the volatility should be modelled by a stochastic process and the (1993) Heston Model is one of many proposed solutions to remedy this problem. The Heston Model allows for the 'smile' by defining the volatility as a stochastic process. This thesis considers a …

Optimization Of Roadway Electrification Integrating Wireless Power Transfer: Technoeconomic Assessment And Lifecycle Analysis, Braden J. Limb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Electric vehicles are the main technology currently being pursued to reduce dependence on fossil fuels in the transportation sector. These vehicles provide both reduced greenhouse gas emissions and decreased operating costs when compared to conventional internal combustion vehicles, while providing the flexibility to use both renewable and fossil energy. However, these vehicles have seen limited consumer adoption due to their large purchase prices and limited driving range. Both purchase price and driving range are related to the large onboard battery systems required for electric vehicle travel.

One solution to decrease dependence on large battery systems has focused on charging vehicles …

Feasibility Of Wireless Power Transfer For Electrification Of Transportation: Techno-Economics And Life Cycle Assessment, Jason C. Quinn, B. J. Limb, P. Barr

Mechanical and Aerospace Engineering Faculty Publications

Integration of wireless power transfer (WPT) systems in roadways and vehicles represents a promising alternative to traditional internal combustion transportation systems. The economic feasibility and environmental impact of WPT applied to the transportation system is evaluated through the development of engineering system models. For a 20% penetration of the WPT technology in vehicles, results show a 20% reduction in air pollutants, 10% reduction in energy use and CO2 emissions and a societal level payback (defined as total cost of ownership savings compared to a traditional vehicle equal to roadway infrastructure) of 3 years. The modeled system covers 86% of all …

Transportation Economics And Energy, Ali Soltani Sobh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transportation is one of the major energy consuming sectors in the United States. The continued growth in fuel consumption not only increases dependency on foreign oil but also causes environmental issues due to the emissions of greenhouse gas (GHG). High gasoline consumption in the US transportation sector not only raises concerns regarding national energy security, but also poses many questions regarding the resulting environmental impacts of greenhouse gases emissions. Improvement in automobile fuel economy, increase the use of natural gas vehicles and electric vehicles have been proven to be as the policies in controlling oil demand and GHG emissions in …

Slow Rate Sand Filtration With And Without Clinoptilolite: A Comparison Of Water Quality And Filtration Economics, Gordon P. Foreman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Slow rate sand filtration (SSF) amended with a 20 cm surface layer of clinoptilolite, a natural zeolite, was compared to SSF with no amendment in a field scale SSF facility treating 85 m³/d of water. Parameters examined included turbidity, coliforms, and ammonium removal. The control filter with sand and the experimental filter amended with the zeolite were also compared with respect to duration of filter cycle, cold weather operation, and economics.

Amended and unamended filters were approximately equivalent with respect to ammonium and coliform removal at 10° C. The zeolite amended cell was superior to the unamended cell …
