Depositional History Of The Trinity-Tiger Shoals Region : A Transgressed Delta Complex Of The Middle Holocene Mississippi Delta, Clint Hoyt Edrington Jan 2013

Depositional History Of The Trinity-Tiger Shoals Region : A Transgressed Delta Complex Of The Middle Holocene Mississippi Delta, Clint Hoyt Edrington

LSU Doctoral Dissertations

The Holocene Mississippi River Delta is arguably the world’s most thoroughly researched deltaic system. However, much of this research has occurred predominantly within the present-day subaerial delta, whereas comparatively little research has been attempted downdip within the offshore, more difficult-to-reach parts. This study advances our understanding of the Holocene delta by examining deltaic sediments within the Trinity-Tiger Shoals Complex region, located ~ 30 – 40 km offshore of central Louisiana. Specifically, this study addresses two questions. Which delta complex prograded into this offshore region? Do the overlying transgressive deposits reflect that predicted by the prevailing transgressive depositional systems model? To …

Using Formative Assessment To Enhance Student Performance On Geometric Proof Writing, Benjamin Hargrave Jan 2013

Using Formative Assessment To Enhance Student Performance On Geometric Proof Writing, Benjamin Hargrave

LSU Master's Theses

The purpose of this research is to uncover best practices to create competent proof writers. Studies have shown the best setting to do this is in the high school geometry classroom. Throughout a yearlong study of geometry, students were exposed to theorems and their demonstrations. Despite constant exposure, students were still unable to produce their own proof of propositions. The questions then became how can an educator provide critical feedback that encourages student reasoning and develops logical argumentation skills? With the goal in mind, twenty-five students enrolled in a geometry course at Baton Rouge High School in Baton Rouge, Louisiana …

The Diagnosis Of Well Control Complications During Managed Pressure Drilling, Brian Piccolo Jan 2013

The Diagnosis Of Well Control Complications During Managed Pressure Drilling, Brian Piccolo

LSU Master's Theses

The constant bottom-hole pressure method of managed pressure drilling is generally expected to reduce well control risks and apply well understood concepts when a kick is taken. Nevertheless, complications, such as operator error, leaks, plugging, equipment failures, and exceeding kick tolerance, can occur during kick circulation. By not properly interpreting the symptoms of a complication, a driller risks the consequences of additional influx, lost circulation or the simultaneous occurrence of both. To address the challenge of diagnosing complications, the implied pit gain (IPG) method is being evaluated as an enhancement to established industry practices. Traditional diagnostic methods attempt to match …

Community Resilience To Coastal Hazards : An Analysis Of Two Geographical Scales In Louisiana, Chi Li Jan 2013

Community Resilience To Coastal Hazards : An Analysis Of Two Geographical Scales In Louisiana, Chi Li

LSU Master's Theses

Quantifying resilience is difficulties due to the different definitions of resilience, the interchangeable uses with two other terms “vulnerability” and “adaptability”, as well as the lack of consensus on what indicators should be selected to quantifying resilience. This thesis research studied the community resilience in Louisiana by applying the Resilience Inference Measurement (RIM) model at two geographic levels: county level and zip code level. The RIM model accesses resilience by using three dimensions (exposure, damage, and recovery) and two abilities (vulnerability and adaptability). The types of coastal hazards included in this study were: coastal, flooding, hurricane/tropical storm, tornado, and severe …

Parallel Suffix Tree Construction For Genome Sequence Using Hadoop, Umesh Chandra Satish

LSU Master's Theses

Indexing the genome is the basis for many of the bioinformatics applications. Read mapping (sequence alignment) is one such application to align millions of short reads against reference genome. Several tools like BLAST, SOAP, BOWTIE, Cloudburst, and Rapid Parallel Genome Indexing with MapReduce use indexing technique for aligning short reads. Many of the contemporary alignment techniques are time consuming, memory intensive and cannot be easily scaled to larger genomes. Suffix tree is a popular data structure which can be used to overcome the demerits of other alignment techniques. However, constructing the suffix tree is highly memory intensive and time consuming. …

Differentiation Of Voice Disorders Using Objective Parameters From Harmonic Waveform Modeling In High-Speed Digital Imaging, Aimee Elaine Perkins Jan 2013

Differentiation Of Voice Disorders Using Objective Parameters From Harmonic Waveform Modeling In High-Speed Digital Imaging, Aimee Elaine Perkins

LSU Master's Theses

High-speed digital imaging (HSDI) has recently become clinically available for the direct observation of vocal fold movement in the last 20 years. However, before it can become routinely used in the clinical setting, a universal means of objectively analyzing and interpreting the HSDI data must be established. In this study, preliminary data was gathered for five parameters used to objectively analyze vocal fold vibratory patterns observed with HSDI. The parameters investigated were established by Ikuma, Kunduk, and McWhorter (2012a) and were previously studied with a small sample (N=8) comparing pre and post-phonosurgical removal of benign lesions. The five parameters included …

Subsurface Stratigraphic Architecture Of Pleistocene Sediments In The Greater New Orleans Area, James Ayrer Jan 2013

Subsurface Stratigraphic Architecture Of Pleistocene Sediments In The Greater New Orleans Area, James Ayrer

LSU Master's Theses

A major environmental and economic problem currently faces the New Orleans area, in southeastern Louisiana, stemming from salinization of freshwater aquifers that are important resources for the community. Major pumping of these aquifers has altered the potentiometric flow, allowing saltier bodies of water to flow into the region. The impact of pumping wells on encroachment of saltwater and the time as well as the route for saltwater to travel from the current saltwater-freshwater interface to pumping centers is not well constrained. Water planners need additional information to make decisions about future management of groundwater resources. The most effective way to …

Effects Of Predator Reduction On Nest Success Of Upland Nesting Ducks In Low-Grassland Density Landscapes In Eastern North Dakota, Michael Buxton Jan 2013

Effects Of Predator Reduction On Nest Success Of Upland Nesting Ducks In Low-Grassland Density Landscapes In Eastern North Dakota, Michael Buxton

LSU Master's Theses

Nest success of upland nesting ducks is the primary driver of duck population growth in the Prairie Pothole Region. Nest success is greatly influenced by nest predation and the amount of available nesting cover on the landscape. The decline in acres enrolled in the Conservation Reserve Program (CRP) in this region has negatively impacted the amount of available nesting cover, making nesting cover sparse and confined to small patches where predation rates are potentially elevated. I evaluated the efficacy of seasonal predator reduction on increasing nest success on low-grassland density (>10% grassland cover), 93 km2 landscapes in two different …

Development Of Watershed-Based Modeling Approach To Pollution Source Identification, Yangbin Tong Jan 2013

Development Of Watershed-Based Modeling Approach To Pollution Source Identification, Yangbin Tong

LSU Master's Theses

Identification of unknown pollution sources is essential to environmental protection and emergency response. A review of recent publications in source identification revealed that there are very limited numbers of research in modeling methods for rivers. What’s more, the majority of these attempts were to find the source strength and release time, while only a few of them discussed how to identify source locations. Comparisons of these works indicated that a combination of biological, mathematical and geographical method could effectively identify unknown source area(s), which was a more practical trial in a watershed. This thesis presents a watershed-based modeling approach to …

Evaluation Of Thermal Insulation By Coal Beds In The Western Arkoma Basin, Ok And Implications For Large Scale Geothermal Resources, Matthew Freeman Jan 2013

Evaluation Of Thermal Insulation By Coal Beds In The Western Arkoma Basin, Ok And Implications For Large Scale Geothermal Resources, Matthew Freeman

LSU Master's Theses

Weighted average geothermal gradients in the Western Arkoma Basin, Oklahoma are estimated from bottom hole temperatures (BHT) from 158 oil and gas wells. The regional geothermal gradient is 28.8 °C/km. The central and north central portions of the basin have higher gradients than southern and northern portions, especially in large areas of Pittsburg and Haskell counties where geothermal gradients in excess of 36 °C/km exist. These gradients suggest that temperatures suitable for low temperature geothermal power exist at depths of 2-3 km. Coals have very low thermal conductivity (0.15 – 0.5 W/m°K) acting as thermal insulators. This study examines the …

The Development Of An Ac Magneto- Optic Kerr Effect System For The Characterization Of Pulsed Laser Deposited Co₂Mnsi-Xal1-X Heusler Alloy Thin Films, Matthew Stephen Champagne

LSU Master's Theses

The Kerr rotation and Kerr ellipticity of thin films can be measured using an AC magneto-optic Kerr effect (AC-MOKE) system. The longitudinal MOKE measurements were taken for a series of Co2MnSixAl1-x thin films with values of x= 0.00, 0.25, 0.50, 0.75, 1.00. The films were fabricated using ultra high vacuum, pulsed laser deposition (PLD) techniques. The PLD targets were made using conventional arc-melting techniques. Using a Jones matrix analysis, it was shown that the Kerr rotation and Kerr ellipticity can be measured separately using two optical setups by taking advantage of a photoelastic modulator and lock-in techniques.

Adaptive Stochastic Conjugate Gradient Optimization For Temporal Medical Image Registration, Huanhuan Xu Jan 2013

Adaptive Stochastic Conjugate Gradient Optimization For Temporal Medical Image Registration, Huanhuan Xu

LSU Master's Theses

We propose an Adaptive Stochastic Conjugate Gradient (ASCG) optimization algorithm for temporal medical image registration. This method combines the advantages of Conjugate Gradient (CG) method and Adaptive Stochastic Gradient Descent (ASGD) method. The main idea is that the search direction of ASGD is replaced by stochastic approximations of the conjugate gradient of the cost function. In addition, the step size of ASCG is based on the approximation of the Lipschitz constant of the stochastic gradient function. Thus, this algorithm could maintain the good properties of the conjugate gradient method, meanwhile it uses less gradient computation time per iteration and adjusts …

Exploring Student Perseverance In Problem Solving, Angelique Renee (Treadway) Duncker Jan 2013

Exploring Student Perseverance In Problem Solving, Angelique Renee (Treadway) Duncker

LSU Master's Theses

ABSTRACT Many high school Geometry students lack the perseverance required to complete complex and time-consuming problems. This project tests the hypothesis that if students were provided with a means of organizing their problem solving work they will be less apt to quit when faced with complex and time-consuming mathematical problems. This study involved students enrolled in 10th grade Geometry and 10th grade Honors Geometry in two similar high schools. After trying unsuccessfully to implement methods adapted from an engineering workshop, I designed a graphic organizer that was simple to use and acceptable to the students. Ultimately, I did not detect …

Simple And Fast Reconstruction Of 6 Mv Radiotherapy Doses To The Whole Body, Lydia Joyce Wilson

LSU Master's Theses

Background: State-of-the-art radiotherapy medical records include reliable estimates of the therapeutic radiation but are known to underestimate the stray radiation exposures by 40% away from the treatment field. Most commonly, stray radiation exposures are reconstructed using empirical formulas and/or lookup tables containing machine-specific dose measurements. The purpose of this study was to develop a physics-based model to calculate exposures to the whole body of patients who receive external beam photon radiotherapy. Methods: We developed a physics-based analytic algorithm to predict absorbed dose from therapeutic, scatter, and leakage radiation. The model includes separate terms to characterize photon production, attenuation, and scattering …

Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante Jan 2013

Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante

LSU Master's Theses

Reducing added salt in processed foods is one of the major challenges facing food industry worldwide. Salt (NaCl) replacement in a Cheddar cheese has been successfully achieved up to 25%, which qualifies it as “reduced sodium”. However, a low sodium cheddar cheese (less than 140 mg Na/ 50 g cheese) requires at least 50% of salt reduction. Bitterness is one obstacle for development of an acceptable low sodium cheddar cheese. In this study, sensory optimization of low sodium white cheddar cheese was performed. A 3-component mixture design was used: NaCl (30-60%), KCl (45-65%) and glycine (5-10%). A fixed level of …
