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 …

Developing A Digital Contents Valuing Model: How Users Appreciate Their Values, Changsu Kim, Jongheon Kim

Journal of International Technology and Information Management

The principal objective of this paper was to propose and verify a digital content valuing model, which is expected to perform a significant role in future research, and provide novel and practical implications. For the efficacy of a model for the evaluation of digital content value, this study reviewed digital content value and categorized it into intrinsic, interaction, and business value. Based on the research model, we attempted to identify and assess the effects of intrinsic digital content value on digital content interaction value, and to characterize the relationship between digital content interaction value and digital content business value. Consequently, …

Identification Of Reverse Engineering Candidates Utilizing Machine Learning And Aircraft Cannibalization Data, Marc Banghart

International Journal of Aviation, Aeronautics, and Aerospace

As military aircraft continue to remain in service and age, cannibalization of parts is increasing. Proactive identification of parts that are at high risk for cannibalization will inform engineering processes such as reverse engineering, thus allowing potentially reducing lead time to develop new parts. The research objective was to develop a causal structure that can be used for prediction of when cannibalization actions may occur. Bayesian networks allow encoding of causality between various descriptive features given a data set. The method utilized a tabu search algorithm, identified the underlying causal structure and the associated node probabilities. The method is then …

Evaluating Process Improvement Courses Of Action Through Modeling And Simulation, Joseph R. Owens

Theses and Dissertations

Quantifying an expected improvement when considering moderate-complexity changes to a process is time consuming and has potential to overlook stochastic effects. By modeling a process as a Numerical Design Structure Matrix (NDSM), simulating the proposed changes, and evaluating performance, quantification can be rapidly accomplished to understand stochastic effects. This thesis explores a method to evaluate complex process changes within Six Sigma DMAIC process improvement to identify the most desirable outcome amongst several improvement options. A tool to perform the modeling and evaluation is developed. This process evaluation tool is verified for functionality, then is demonstrated against generic processes, a case …
