Development Of A Novel Kalman Filter Bank Predictor To Optimally Schedule The Renewable Energy Contribution Within A Micro-Grid, Conor Lynch

Theses

This PhD thesis presents a novel Kalman Filter Bank (KFB) methodology. The novel KFB is applied to predict and optimally schedule the operation of micro-grid energy resources with a public fixed-grid connection and an auxiliary battery storage backup facility. This methodology relies on a sliding single time step forecast projection to accurately acquire the anticipated schedule for a range of time dependent parameters, stochastic by nature, that have inherent embedded cyclical patterns. The innovative feature here consists of a novel bank of hourly adjacent Kalman Filter estimators, which operate in synchronism, for accurate parameter prediction over a selected time horizon. …

The Effects Of Elevated Co2 Levels On Broad Bean, Vicia Faba, Growth/Defense Tradeoffs, Harley B. Kitching

Honors College Theses

Atmospheric changes, associated with global climate change, are increasing at an unprecedented rate. Plants generally display higher rates of growth in response to elevated CO₂ levels, but this response varies among species. In addition, very little is known about how plant growth/defense tradeoffs will be altered by increasing CO₂ levels. By raising Broad bean, Vicia faba L., plants under ambient (400 ppm) and elevated (900 ppm) levels of CO₂, it was shown that atmospheric composition directly altered plant growth/defense tradeoffs. Plants grown under elevated CO₂ had lighter stem weights but greater numbers of extrafloral nectaries …

In December 2014, General Motors closed its flagship Opel plant in Bochum after 52 years of operation amidst years of economic struggles in the industrial Ruhr-valley region of northwestern Germany, marking the first closure of a major German automobile plant since 1945. This study examines the primary underlying causes of the landmark closure, such as the insolvency of GM-Opel and tense employer-employee relations compounded by unsatisfactory trade union negotiations between GM-Opel and IG Metall. Subsequent social and economic reactions to the closure are also examined, including the yearlong “This is not Detroit” campaign launched by local Bochum artists to inspire …

Don Quixote, Man Of Ink, Nicholas J. Shuber

Honors College Theses

The story of El ingenioso hidalgo Don Quixote de la Mancha by Miguel de Cervantes is a novel that has transgressed throughout the years in the forefront of Hispanic literature. The story is a satire to most people, laughing about the idiocy of the books of knight-errantry. Don Quixote has been analyzed as such a comedy ever since its release, and this idea has affected the perspectives of everyone who has researched it before. However, an argument could be made that this is indeed not the only way that the novel can be seen. The idea that is purported in …

The Effects Of Carboxylic Acids In Aluminum Anodizing, Abby E. Koczera

Honors Theses and Capstones

Hard-anodized alumina coatings were formed in sulfuric acid at low temperature and high current density in the presence of carboxylic acid additives. Citric acid, trimesic acid, mellitic acid and ethylenediaminetetraacetic acid (EDTA) were utilized in varying concentrations. The additives were chosen for their capacity to form complexes with tri-valent aluminum and hence impart chemical stability to the coatings. The coatings were sealed in boiling water, and corrosion resistance was observed in a high pH solution of potassium hydroxide. The coatings were examined using scanning electron microscopy (SEM) to assess coating thickness and pore dimensions. Thicker coatings were produced when the …

Flooding And Inundation Modeling In The Great Bay Estuary, Anna E. Simpson

Honors Theses and Capstones

As part of this research, FVCOM, a finite-volume coastal ocean numerical hydrodynamic model (Chen, et al., 2003), was implemented into the Great Bay estuary. FVCOM is one of several community models that have been developed for coastal regions, and was selected because it utilizes an unstructured grid to discretize the model domain. The unstructured grid provides the ability to have fine scale resolution near the boundary or coastline and decreased resolution away from the boundary where the flow field is less complicated, resulting in greatly reduced computational expense in less dynamic regions allowing model runs to be completed in …
