Land Use Interactions Drive Southwestern Ontario Stream Nutrient Concentrations, Renee L. Lazor
Land Use Interactions Drive Southwestern Ontario Stream Nutrient Concentrations, Renee L. Lazor
Electronic Thesis and Dissertation Repository
Human activities have transformed the landscape and altered natural habitats through intensive land uses including agriculture and urbanization. Identifying land use drivers of tributary nutrient concentrations and describing the magnitude and direction of their relationship are critical activities to improvement management of water quality in basins draining into the Great Lakes. The overarching goal of my thesis was to quantify the cumulative influence of spatial patterns in land use and land cover on variation of nutrient concentrations in tributaries of the Great Lakes. Biweekly water chemistry samples were collected in 29 streams located in southern Ontario between May and November, …
Environmental Health Effects Of Multiple Exposures: Systemic Risks And The Detroit River International Crossing Study, Tor H. Oiamo
Environmental Health Effects Of Multiple Exposures: Systemic Risks And The Detroit River International Crossing Study, Tor H. Oiamo
Electronic Thesis and Dissertation Repository
This thesis examines cumulative exposures to traffic noise and outdoor air pollution on environmental and health related quality of life in Windsor, Ontario, and provides a critical analysis of the environmental assessment process for the Detroit River International Crossing (DRIC) Study. The research utilizes a systemic risk framework to understand environmental health and stress effects of cumulative exposures. The significance of this research is based on a relative absence of literature on the systemic health risks of cumulative exposures and the need to elucidate environmental annoyance as a health outcome for risk assessment. The objectives of the research were to …
Identification Of Informativeness In Text Using Natural Language Stylometry, Rushdi Shams
Identification Of Informativeness In Text Using Natural Language Stylometry, Rushdi Shams
Electronic Thesis and Dissertation Repository
In this age of information overload, one experiences a rapidly growing over-abundance of written text. To assist with handling this bounty, this plethora of texts is now widely used to develop and optimize statistical natural language processing (NLP) systems. Surprisingly, the use of more fragments of text to train these statistical NLP systems may not necessarily lead to improved performance. We hypothesize that those fragments that help the most with training are those that contain the desired information. Therefore, determining informativeness in text has become a central issue in our view of NLP. Recent developments in this field have spawned …
Options Pricing And Hedging In A Regime-Switching Volatility Model, Melissa A. Mielkie
Options Pricing And Hedging In A Regime-Switching Volatility Model, Melissa A. Mielkie
Electronic Thesis and Dissertation Repository
Both deterministic and stochastic volatility models have been used to price and hedge options. Observation of real market data suggests that volatility, while stochastic, is well modelled as alternating between two states. Under this two-state regime-switching framework, we derive coupled pricing partial differential equations (PDEs) with the inclusion of a state-dependent market price of volatility risk (MPVR) term.
Since there is no closed-form solution for this pricing problem, we apply and compare two approaches to solving the coupled PDEs, assuming constant Poisson intensities. First we solve the problem using numerical solution techniques, through the application of the Crank-Nicolson numerical scheme. …
Cosine Similarity For Article Section Classification: Using Structured Abstracts As A Proxy For An Annotated Corpus, Arthur T. Bugorski
Cosine Similarity For Article Section Classification: Using Structured Abstracts As A Proxy For An Annotated Corpus, Arthur T. Bugorski
Electronic Thesis and Dissertation Repository
During the last decade, the amount of research published in biomedical journals has grown significantly and at an accelerating rate. To fully explore all of this literature, new tools and techniques are needed for both information retrieval and processing. One such tool is the identification and extraction of key claims. In an e ort to work toward claim-extraction, we aim to identify the key areas in the body of the article referred to by text in the abstract. In this project, our work is preliminary to that goal in that we attempt to match specific clauses in the abstract with …
