Thermogenic Gas Hydrate Formation In Gulf Of Mexico Offshore Environment- Results From Numerical Simulation, Sulav Dhakal

LSU Master's Theses

Development of civilization and the resulting quest for energy have led us to previously uncharted territory in exploration and production of fuel. As the demand continues to grow and conventional oil reserves become depleted, we are looking into unconventional resources such as gas hydrates. However, due to the volatile nature of the energy market and production technology yet to perfected, we are not able to fully utilize the potential of gas hydrates yet.

Reservoir characterization of hydrates have so far been limited to seismic mapping, well log interpretation and laboratory scale studies. This research uses numerical simulation to understand the …

Mechanical And Physical Properties Of Fluorogypsum-Cement-Fly Ash Blends For Artificial Reef And Coastal Protection Structures, Yasser Bigdeli

LSU Doctoral Dissertations

The State of Louisiana faces severe soil erosion along its coastlines. Coastal protection structures most commonly are made of limestone and concrete. However, in Louisiana, these materials are not widely available, which makes it significantly expensive to protect the coastlines and marine life. This study proposes to use locally available materials that have lower cost and lower density than limestone and concrete to reduce the economic burden of protecting and enhancing coastlines.

This study presents an extensive investigation of strength and durability properties of a low-cost concrete-like composite material made of pH-adjusted fluorogypsum (FG), class C fly ash (FA), and …

Essays On Estimation For Nonlinear Spatial Models, Xiaoyu Zhou

LSU Doctoral Dissertations

This dissertation consists of three essays that contribute to the literature on the estimation of nonlinear spatial panel models. Chapter 2 investigates the performance of both the spatial autocorrelation probit model (SAR) and the spatial error correlation probit model (SEM) with the consideration of temporal effects under the panel data framework. The recursive importance sampling (RIS) method is adopted to compute the integral of the multivariate normal distributed error terms. Chapter 3 estimates a panel probit model with individual fixed effects. A spatial error process and conditional heteroskedasticity in an exponential form is considered. We derive the analytical solution for …

Exploring Alternative Giant Salvinia (Salvinia Molesta D.S. Mitchell) Management Strategies, Bradley T. Sartain

LSU Doctoral Dissertations

Dense infestations of the free-floating aquatic fern giant salvinia (Salvinia molesta D.S. Mitchell) have been expanding across the southeastern United States for over two decades. Although herbicide programs have provided relief to giant salvinia infested areas, morphology and growth characteristics make management difficult. A series of mesocosm trials were conducted to explore alternative management strategies for giant salvinia. Evaluation of non-registered aquatic herbicides showed that rates of sulfometuron and metsulfuron controlled giant salvinia and provided a 98 to 100% biomass reduction. An outdoor mesocosm trial evaluated potential glyphosate resistance in giant salvinia in select water bodies throughout Louisiana. Differences …

Developing Nanopore Electromechanical Sensors With Transverse Electrodes For The Study Of Nanoparticles/Biomolecules, Mohammadsadegh Beheshti

LSU Doctoral Dissertations

This study concerns development of a technology of utilizing metallic nanowires for a sensing element in nanofluidic single molecular (nanoparticle) sensors formed in plastic substrates to detect the translocation of single molecules through the nanochannel. We aimed to develop nanofluidic single molecular sensors in plastic substrates due to their scalability towards high through and low cost manufacturing for point-of-care applications. Despite significant research efforts recently on the technologies and applications of nanowires, using individual nanowires as electric sensing element in nanofluidic bioanalytic devices has not been realized yet. This dissertation work tackles several technical challenges involved in this development, which …

Image Processing Applications In Real Life: 2d Fragmented Image And Document Reassembly And Frequency Division Multiplexed Imaging, Houman Kamran Habibkhani

LSU Doctoral Dissertations

In this era of modern technology, image processing is one the most studied disciplines of signal processing and its applications can be found in every aspect of our daily life. In this work three main applications for image processing has been studied.

In chapter 1, frequency division multiplexed imaging (FDMI), a novel idea in the field of computational photography, has been introduced. Using FDMI, multiple images are captured simultaneously in a single shot and can later be extracted from the multiplexed image. This is achieved by spatially modulating the images so that they are placed at different locations in the …

Weary At Work: A Conservation Of Resources Approach To Understanding Job-Related Boredom, Candace Angela Esken

LSU Doctoral Dissertations

Despite the pervasive nature of boredom in the workplace, there has been surprisingly little theoretical and empirical analysis on the phenomenon. The existing research suffers from several shortcomings preventing progress on job-related boredom including the lack of an agreed definition and a properly developed and validated measure of the construct. This dissertation addresses these deficiencies by first developing and validating a psychometrically sound measure for job-related boredom. Then, drawing upon conservation of resources theory, hypotheses for the antecedents and consequences of job-related boredom were tested using a sample of 199 employees at a large insurance organization in the United States. …

The Well-Rounded Musician: A New Degree Path For Horn In Jazz, Lauren M. Braud

LSU Doctoral Dissertations

The following document will examine the question of whether horn players should be trained in jazz at the collegiate level. Should research prove that teaching horn players to play jazz is a viable degree, how should it be done? How should it be taught? Should classical training be dropped from the curriculum for these students?

A brief history of jazz and horn players who were well known for their performance and study of jazz are discussed. The main research portion contains a survey of current jazz professors and performers. The survey looks into the formal training of these professors and …

Mobility Of Nano-Particles In Rock Based Micro-Models, Jagannath Upadhyay

LSU Doctoral Dissertations

A confocal micro-particle image velocimetry (C-μPIV) technique along with associated post-processing algorithms is detailed for obtaining three dimensional distributions of nano-particle velocity and concentrations at select locations of the 2.5D (pseudo 3D) Poly(methyl methacrylate) (PMMA) and ceramic micro-model. The designed and fabricated 2.5D micro-model incorporates microchannel networks with 3D wall structures with one at observation wall which resembles fourteen morphological and flow parameters to those of fully 3D actual reservoir rock (Boise Sandstone) at resolutions of 5 and 10 μm in depth and 5 and 25 μm on plane. In addition, an in-situ, non-destructive method for measuring the geometry of …

P3: Phylogenetic Posterior Prediction In Revbayes, Sebastian Höhna, Lyndon M. Coghill, Genevieve G. Mount, Robert C. Thomson, Jeremy M. Brown

Faculty Publications

© The Author 2017. Published by Oxford University Press on behalf of the Society for Molecular Biology and Evolution. Tests of absolute model fit are crucial in model-based inference because poorly structured models can lead to biased parameter estimates. In Bayesian inference, posterior predictive simulations can be used to test absolute model fit. However, such tests have not been commonly practiced in phylogenetic inference due to a lack of convenient and flexible software. Here, we describe our newly implemented tests of model fit using posterior predictive testing, based on both data- and inference-based test statistics, in the phylogenetics software RevBayes. …
