Numerical Modeling Of Mobile Bay, Tate O. Mcalpin

Theses and Dissertations

A numerical model was developed for the Mobile Bay system to investigate the impacts associated with certain system alterations. The Adaptive Hydraulics (AdH) Code was used to validate the numerical model for hydrodynamics and transport. Due to the physics based nature of the AdH numerical model, the validated model could be altered to represent the plan conditions (removal of the Mobile Bay Causeway). Comparisons of the base and plan model results indicate the impacts of removing the causeway are not widespread and are primarily limited to Chocolatta Bay and the areas adjacent to the causeway. The model results suggest an …

Spatial Error Metrics And Registration For The Validation Of Numerical Oceanographic Models, Sean B. Ziegeler

Theses and Dissertations

Numerical oceanographic models are constantly improving and must be validated when improvements are made. One means of determining how to improve these models and performing validations is to compare model predictions to the future observed outcome, which is measured many ways, including satellite imagery. Comparisons of model forecasts to future satellite images result in error measurements. One common problem with modern oceanographic models is spatial error, i.e., the incorrect placement and shape of ocean features, rendering traditional error metrics such as mean-square and cross-correlation ineffective. Such problems are common in meteorological forecast verification as well, so the application of spatial …

However, after the typhoon passed by the island at 2100 LST, September 7, the SST decreased by 2°C to 25°C. Asymmetrical-cyclonic surface wind generated by …

Blow-Up Of Solutions To The Generalized Inviscid Proudman-Johnson Equation, Alejandro Sarria

LSU New Orleans Theses and Dissertations

The generalized inviscid Proudman-Johnson equation serves as a model for n-dimensional incompressible Euler flow, gas dynamics, high-frequency waves in shallow waters, and orientation of waves in a massive director field of a nematic liquid crystal. Furthermore, the equation also serves as a tool for studying the role that the natural fluid processes of convection and stretching play in the formation of spontaneous singularities, or of their absence.

In this work, we study blow-up, and blow-up properties, in solutions to the generalized, inviscid Proudman-Johnson equation endowed with periodic or Dirichlet boundary conditions. More particularly,regularity of solutions in an Lp setting will …

Automatic Object Recognition And Registration Of Dynamic Heavy Equipment Using A Hybrid Ladar System, Mengmeng Gai

Department of Construction Engineering and Management: Dissertations, Theses, and Student Research

It has been a challenging subject to recognize dynamic objects from a scattered work environment because large and complex 3D site data obtained by a laser scanner makes it difficult to process itself in real or near real time. This thesis introduces a model-based automatic object recognition and registration framework, Projection-Recognition-Projection (PRP), to assist heavy equipment operators in rapidly perceiving 3D working environment at dynamic construction sites. In this study, a digital camera and a hybrid laser scanner were used to rapidly recognize and register dynamic target objects in a 3D space by separating target object’s point cloud data from …

Rainwater Utilization To Reduce Flooding In Low-Lying Areas Of Taipei City, Taiwan, Andrew Lo

Journal of Marine Science and Technology–Taiwan

She-Zih is a low-lying area in Taipei City where the Tanshui River and Keelung River meet. Average elevation is about 2.5 m. Perennial flood events occur very often. The only flood prevention facility is the 6 m levee built around the perimeter to overcome 20-yr flood events. The main cause of the flooding problem is the instantaneous extreme high rainfall events that often exceed the drainage capacity of She-Zih. Current solutions to relieve this water hazard, suggested by the Water Resources Agency, include channel widening and many water pumping installations. At present, all emergency facilities are insufficient to combat unexpected …

"Go, Going, Gone": Anti-Chinese Sentiment In Washington Territory, 1885-1886, Naomi Eide

History & Classics Undergraduate Theses

Unwilling to conform to the pressure set forth by the national government, the citizens of Washington Territory, during 1885 and 1886, united to purge the region of the Chinese through a systematic ethnic cleansing of two major territorial cities. Motivated by the desire to become active members of the federal government, Territorial leaders ignored the negative effects of population exclusion and led an active movement rallying around the cry that “the Chinese must go.” Not until the lawlessness of the rioters shut down the territorial government, did the political agitators acknowledge how outsiders perceived their drastic actions, realizing that the …

The Failures Of Intelligence Reform, Amber Ciemniewski

Honors Theses

Intelligence reform is the legislation implemented by the federal government that's purpose is to improve the effectiveness and success of the intelligence community. It would seem evident that intelligence reform has failed, but the more important questions lie in where it has failed and how to fix it. In this thesis, it will be argued that reform attempts have failed by focusing on surface problems rather than addressing their sources. Future reforms should focus on the relationship dynamic between the intelligence community and the policymakers it serves. There has been extensive literature published on the problems in the intelligence community …

Education, Employment, And Coastal Carolina University: What Are Ccu Students' Plans After Graduation?, Thomas M. Fernandez

Honors Theses

The Bureau of Labor Statistics has shown that while unemployment amongst young college graduates is high, joblessness decreases as students pursue post-baccalaureate degrees. And with national unemployment near 8 percent, it is important for college students to consider what obstacles they may face when entering the workforce. Challenges may include sociohistorical (parent educational attainment) and socioeconomic factors as well as obstacles surrounding various forms of human capital. Using some of these challenges youth face when entering college and/or the workforce, this study predicts the decisions Coastal Carolina University (CCU) students will make post-graduation based upon four elements: parental education, academic …

Interferometric Synthetic Aperture Sonar Signal Processing For Autonomous Underwater Vehicles Operating Shallow Water, Patricia E. Giardina

LSU New Orleans Theses and Dissertations

The goal of the research was to develop best practices for image signal processing method for InSAS systems for bathymetric height determination. Improvements over existing techniques comes from the fusion of Chirp-Scaling a phase preserving beamforming techniques to form a SAS image, an interferometric Vernier method to unwrap the phase; and confirming the direction of arrival with the MUltiple SIgnal Channel (MUSIC) estimation technique. The fusion of Chirp-Scaling, Vernier, and MUSIC lead to the stability in the bathymetric height measurement, and improvements in resolution. This method is computationally faster, and used less memory then existing techniques.

Calculation Of A Synthetic Gather Using The Aki-Richards Approximation To The Zoeppritz Equations, Graham Ganssle

LSU New Orleans Theses and Dissertations

A synthetic seismic gather showing amplitude versus offset can be analyzed by the interpretive geophysicist to predict rock properties useful in oil exploration. Reflection coefficients derived from measured well log data are convolved with a Ricker wavelet to create a synthetic seismic trace. The Zoeppritz equations describe the propagation of an acoustic wave across an interface between two viscous media of different acoustic impedances with respect to increasing offset angle. The Aki-Richards linear approximation is used to create a synthetic seismic gather with offset angles up to fifty degrees. This gather is compared to a synthetic gather created using commercially …
