Overwash Controls on Barrier Island Morphodynamics during Storms
Get PDFOverwash, shoreface retreat, and barrier migration are common processes occurring in transgressive barrier island systems, the scale of which is exacerbated by sea level rise, subsidence and the frequency and magnitude of tropical and extratropical storms. Barrier morphology also clearly plays a key role in determining a morphological response to these processes. Using a hydrodynamic and sediment transport model (MIKE21) and selected barrier island and shoreface templates, informed by deltaic and coastal plain systems in the northern Gulf of Mexico, I performed simulations to determine barrier morphology in response to storms. A low dune with a gentle shoreface slope, characteristic of Louisiana deltaic barriers, demonstrates the greatest amount of shoreline erosion, dune overwash and barrier migration in response to a storm. Profile evolutions over time demonstrate the wider dune templates respond mostly via dune aggradation and barrier rollover whereas the narrow or low templates respond via dune overwash and barrier translation. Determining which barrier templates retain the most sediment over time becomes extremely important when planning coastal restoration projects here in Louisiana
Always the Icarus
Get PDFAlways the Icarus is an experimental play in two acts depicting the road-trip journey of meth-fueled, anti-heroine, Cartla, and her best friend, J.A. –a Juggalo with a heart of gold. Cartla desperately needs to leave the Midwestern nothingness of Interior, South Dakota after having a premonition about the fate of America’s favorite T.V. food guy, Guy Fieri. The lines between memory and vivid hallucination become desperately scrambled for the young, twisted duo as they venture from stop to stop along the lucid route to Anaheim, California. With each passing stop, Cartla is confronted by her inescapable geo-historical and geo-familial coordinates as well as a whole slew of characters who refuse to accept the idea that the coveted “American dream” may be grossly out of reach for the forgotten “trash” of the nation. But who will be the saviors of the broken and the ambassadors of the underdogs? Do the maneuvers of the father undoubtedly scar the psyche of the oblivious, devoted child? Do mythologies leave room for less-tragic margins of error?Through a theatrical narrative form stressing cyclical language and interactions, audiences are urged to question whether the mythic Icarus will always fall from the soaring, sky-heights of heaven into the cold waters below
Improving a Particle Swarm Optimization-based Clustering Method
Get PDFThis thesis discusses clustering related works with emphasis on Particle Swarm Optimization (PSO) principles. Specifically, we review in detail the PSO clustering algorithm proposed by Van Der Merwe & Engelbrecht, the particle swarm clustering (PSC) algorithm proposed by Cohen & de Castro, Szabo’s modified PSC (mPSC), and Georgieva & Engelbrecht’s Cooperative-Multi-Population PSO (CMPSO). In this thesis, an improvement over Van Der Merwe & Engelbrecht’s PSO clustering has been proposed and tested for standard datasets. The improvements observed in those experiments vary from slight to moderate, both in terms of minimizing the cost function, and in terms of run time
Rust Belt and Other Stories
Get PDFRust Belt and Other Stories is a collection of stories exploring characters in the bleak moments when social oppression challenge the perceived meaning of their lives. The disenchantments are influenced by distinctive settings, which set the tone for the stories. Place is an active force shaping the protagonists and adding to the nuance of character relationships, dialogue and philosophical outlooks
Beginner\u27s Mind
Get PDFMy art distills my relationship to spirituality, digital culture, and the practices and side-effects therein, into a simplified visual language. The work manifests in the form of paintings, drawings, and light sculptures. Meditation and mindfulness training are a large part of my influence and interests. I often wonder how mindfulness practice can be mirrored in my artwork, not only in my process for creating the work, but also with what the resulting imagery does for the viewer. My intention is to provide an art form that invites one to look and experience one’s own capacity to observe, without the need for immediate intellectualization. I wish to offer people an opportunity to focus their attention on the phenomenological sensations that emanate from the art, to take a step back from the conceptual part of the mind, and step into a part that’s more fundamental to our moment to moment reality
Particulate Matter and Carbon Monoxide Emission Factors from Incense Burning
Get PDFIndoor air quality is a growing concern in the world. People spend a considerable amount of time in indoor environments such as homes, workplaces, shopping malls, stores, and so on. Indoor sources like incense and candle burning, cooking contribute a significant amount of indoor air pollutants such as particulate matter, carbon monoxide (CO), volatile organic compounds. Exposure to these kinds of pollutants can result in adverse health effects.
The purpose of this research is to determine the particulate matter and carbon monoxide emission factors (EFs) from incense stick burning. A test chamber with a rectangular exhaust duct, a fan to exhaust air with pollutants in it, and pollutant sensors were used to achieve the project goals. Several experiments were performed with different cases/scenarios to accurately estimate the EFs and several test runs were conducted for each case to test the repeatability of the results.
The CO, PM2.5 (mass), PM2.5 (number), PM10 (mass), PM10 (number) EFs developed in this research are between 110-120 mg/g of incense, 2.5-3 mg/g of incense, 800-1100 #particles/µg of incense, 32-33 mg/g of incense, 1200-1400 #particles/µg of incense respectively
Financial Crises and Investment Behavior: The Impact of Institutional Investors
Get PDFThe following dissertation contains two related essays. The first essay explores how institutional investor presence impacts investments during the global financial crisis. Using OLS, industry fixed effects, and Heckman 2SLS regression approaches, I explore two ways through which institutional investors could impact investments: liquidity and monitoring. My findings best support monitoring theory. I find that institutional investors monitor capital and R&D levels to maximize crisis period firm value.
The second essay is a direct fallout from my first essay. In it, I investigate how institutional investor types influence investments. I ask, do certain types of investors improve liquidity or monitor firm investment behavior during the global financial crisis? My results suggest that long-term, dedicated institutional investors monitor firm investments more than short-term, transient investors. As a result, firms with greater dedicated investor presence perform better during the crisis periods than their peers
Seismic Facies Classification of an Intraslope Minibasin in The Keathley Canyon, Northern Gulf of Mexico
Get PDFThis work examines several volume attributes extracted from 3D seismic data with the goal of seismic facies classification and lithology prediction in intraslope minibasins. The study area is in the Keathley Canyon protraction (KC), within the middle slope of the Northern Gulf of Mexico (GOM). It lays within the tabular salt and minibasins province downdip of the main Pliocene and Pleistocene deltaic depocenters. Interaction between sedimentation and mobile salt substrate lead to the emergence of many stratigraphic patterns in the intraslope minibasins. Interest in subsalt formations left above salt formations poorly logged. Facies classification using Artificial Neural Network (ANN) was applied in those poorly logged areas. The resultant facies classes were calibrated and used to predict the lithology of the recognized facies patterns in an intraslope minibasin, away from well control. Three types of facies classes were identified: Convergent thinning, convergent baselaping and bypassing. The convergent baselaping are found to be the most sand rich among all other facies
