Analyzing The Global Changes In The Seasonal Cycle Of Sea Level, Storm Surge, And Ocean Waves, Amanda Barroso

Graduate Thesis and Dissertation post-2024

Changes in the seasonal cycle of extreme sea level components can modulate the flooding risk along coastlines. This dissertation evaluates the changes in and potential co-occurrence of the seasonal cycles of mean sea level, storm surge, and ocean waves. Seasonal cycles characterize the generally expected climate conditions throughout the year with distinct high and low patterns. These regular and predictable cycles have shown non-stationarity in some locations across the globe. This means the timing of the expected peak may shift to occur earlier or later. Shifts in the timing of the maximum sea level impact coastlines with increased risk of …

Design And Development Of A Laser Diagnostic System For Ammonia And Nox Measurements In A Toroidal Jet Stirred Reactor At Atmospheric Pressure, Marzuqa Ahmed

Graduate Thesis and Dissertation post-2024

The need for more sustainable fuel alternatives in the modern aircraft industry is growing. SAF is the current sustainable fuel in use, but still produces harmful carbon emissions. A promising alternative to SAF is ammonia, which produces zero carbon emissions. By decomposing ammonia (NH₃) into its constituents of N₂ and H₂ using a chemical catalyst, a hydrogen-ammonia fuel mix is created. H₂/NH₃ mixtures still have the desired characteristic of burning without carbon emissions, but are less reactive than pure hydrogen. Additionally, ammonia is a widely used compound, so infrastructure already exists for production, …

Firm Capabilities Versus Regional Factors: A Random Forest Approach For Predicting Toxic Chemical Releases Among Us Industrial Facilities, Mahelet G. Fikru, Jennifer Brodmann

Economics Faculty Research & Creative Works

Predicting toxic releases remains a challenge for environmental protection, as effective regulation and mitigation depend on understanding the key drivers behind firms' pollution behavior. We examine the factors that influence firm environmental pollution by determining whether corporate capabilities or regional factors better predict toxic chemical emissions. We combine toxic releases data across 1976 industrial facilities in the United States with firm-level financial performance indicators and regional socio-demography variables to identify the most significant predictors of environmental outcomes. We use a random forest model due to its ability to capture complex, nonlinear interactions among predictors and provide robust variable importance rankings. …

Learning Structure With Multivariate Information Bottleneck And Exploration Of New Methods In Sequential Decision Making, Volodymyr Makarenko

Master's Theses

Research in useful information extraction has been motivated by the increasing demand to extract insights from unstructured data, and by the need to store and transmit great volumes of information, often originating in unstructured data such as videos. Research in rate distortion and information bottleneck paved the path for understanding and guiding the design of lossy encoders, capable of extracting relevant information. Independently, research in deep representation learning has enabled numerous applications for unstructured high-dimensional data such as images. However, the interpretability of the deep learning methods remained limited. Several desired properties of learned representations have been suggested, including disentanglement. …
