Temporal Changes In Quality Of Life And Environment In New Orleans After Hurricane Katrina, Danielle Johanna LaRock 2011 Louisiana State University and Agricultural and Mechanical College

Temporal Changes In Quality Of Life And Environment In New Orleans After Hurricane Katrina, Danielle Johanna Larock

LSU Master's Theses

Understanding and assessing the spatial and temporal changes of quality of life and environment of a community is critical to its sustainable development, especially after a disaster strikes. This study explores an approach that integrates remote sensing with socioeconomic data to assess the temporal changes in quality of life and environment (QOL) using Orleans Parish as an example. Hurricane Katrina, which struck New Orleans in 2005, has had vast implications economically, socially, and environmentally for this city and the surrounding area. Empirically quantifying these concepts will help to rebuild the city more sustainably. This study investigated change in environmental quality ...


Parallel Surrogate Detection In Large-Scale Simulations, Lei Jiang 2011 Louisiana State University and Agricultural and Mechanical College

Parallel Surrogate Detection In Large-Scale Simulations, Lei Jiang

LSU Master's Theses

Simulation has become a useful approach in scientific computing and engineering for its ability to model real natural or human systems. In particular, for complex systems such as hurricanes, wildfire disasters, and real-time road traffic, simulation methods are able to provide researchers, engineers and decision makers predicted values in order to help them to take appropriate actions. For large-scale problems, the simulations usually take a lot of time on supercomputers, thus making real-time predictions more difficult. Approximation models that mimic the behavior of simulation models but are computationally cheaper, namely "surrogate models", are desired in such scenarios. In the thesis ...

Numerical Methods For The Study Of Super-Eddington Mass Transfer In Double White Dwarf Binaries, Dominic Carlo Marcello 2011 Louisiana State University and Agricultural and Mechanical College

Numerical Methods For The Study Of Super-Eddington Mass Transfer In Double White Dwarf Binaries, Dominic Carlo Marcello

LSU Doctoral Dissertations

We present a numerical method for the study of double white dwarf (DWD) binary systems at the onset of super-Eddington mass transfer. We incorporate the physics of ideal inviscid hydrodynamical flow, Newtonian self-gravity, and radiation transport on a three-dimensional uniformly rotating cylindrical Eulerian grid. Our new method conserves total energy to a higher degree of accuracy than recent smoothed particle hydrodynamics methods and our previous Eulerian grid based method. We present the results of verification tests and we simulate the first 20+ orbits of a binary system of mass ratio q=0.7 at the onset of dynamically unstable direct ...

Population Characteristics Of A White-Tailed Deer Herd In An Industrial Pine Forest Of North-Central Louisiana, John Henry Harrelson 2011 Louisiana State University and Agricultural and Mechanical College

Population Characteristics Of A White-Tailed Deer Herd In An Industrial Pine Forest Of North-Central Louisiana, John Henry Harrelson

LSU Master's Theses

White-tailed deer are the most important game species in Louisiana, and throughout the southeastern United States. Likewise, the forest products industry represents the most important agricultural commodity in Louisiana, and industrial landowners frequently lease their properties to sportsmen specifically for white-tailed deer hunting. I conducted research assessing survival, space use, and habitat selection of white-tailed deer on a 3885 ha industrial forest owned by Plum Creek Timber Company. I captured 61 deer in Union Parish, Louisiana in 2009-2010, radio-marked 24 females and 23 males, and ear-tagged 7 females and 6 males. Season and sex interacted to affect home range and ...


Geomicrobiology Of Louisiana Coastal Marshes Before And After The Deepwater Horizon Oil Spill, Chang Liu 2011 Louisiana State University and Agricultural and Mechanical College

Geomicrobiology Of Louisiana Coastal Marshes Before And After The Deepwater Horizon Oil Spill, Chang Liu

LSU Master's Theses

The 2010 Deepwater Horizon oil spill in the Gulf of Mexico not only impacted open ocean and shoreline geochemical and ecological environments, but it served to promote research of microbial ecosystems in poorly studied habitats, such as Louisiana marshes. Sediment and water samples from four main marshes in southern Louisiana were collected in May 2010 (pre-oil), September 2010 (oiled), and June 2011 (post-oil). Sites near the Mississippi River had exceptionally low salinity in the immediate months following the oil spill due to freshwater diversion efforts; salinity increased by an order of magnitude one year later. Microbial diversity was evaluated from ...


Guided Modes And Resonant Transmission In Periodic Structures, Hairui Tu 2011 Louisiana State University and Agricultural and Mechanical College

Guided Modes And Resonant Transmission In Periodic Structures, Hairui Tu

LSU Doctoral Dissertations

We analyze resonant scattering phenomena of scalar fields in periodic slab and pillar structures that are related to the interaction between guided modes of the structure and plane waves emanating from the exterior. The mechanism for the resonance is the nonrobust nature of the guided modes with respect to perturbations of the wavenumber, which reflects the fact that the frequency of the mode is embedded in the continuous spectrum of the pseudo-periodic Helmholtz equation. We extend previous complex perturbation analysis of transmission anomalies to structures whose coefficients are only required to be measurable and bounded from above and below, and ...


Non-Mass Dependent Isotope Fractionation: An Application In The Hyperarid Environment And A Set Of Experiments On Thermal Diffusion, Tao Sun 2011 Louisiana State University and Agricultural and Mechanical College

Non-Mass Dependent Isotope Fractionation: An Application In The Hyperarid Environment And A Set Of Experiments On Thermal Diffusion, Tao Sun

LSU Doctoral Dissertations

This dissertation consists of two independent topics; both are related to non-mass dependent isotope fractionation. 1) Atacama Gravel Sulfate: The onset of hyperaridity of Atacama Desert is of geological importance and has been controversial. I put constraints this timing by looking into a new record, a deep sulfate profile extending from the surface down to the oxide zone of a copper ore in the Atacama Gravels, whose deposition covers a majority of the Central Depression and temporarily spans from semi-arid to hyper-arid climate. The gravel sulfates show a strong depth-dependent pattern through ~50 meters (15 to 65 meter depth): narrow ...


Social Vulnerability In Louisiana's Upper Industrial Corridor: Spatial Distribution And Linkages With Cumulative Pollution - A Zip Code Level Analysis, María Belén Toscano 2011 Louisiana State University and Agricultural and Mechanical College

Social Vulnerability In Louisiana's Upper Industrial Corridor: Spatial Distribution And Linkages With Cumulative Pollution - A Zip Code Level Analysis, María Belén Toscano

LSU Master's Theses

Louisiana’s industrial corridor, the stretch of the lower Mississippi River from New Orleans to Baton Rouge, is one of the areas with the highest concentration of petrochemical facilities and chemical plants in the United States, as well as one of the most heavily polluted. In particular, the present study examined the associations of social vulnerability and potential exposure to environmental pollution in the upper section of the industrial corridor, the Baton Rouge Metropolitan Statistical Area (MSA). The study was based on the methodology developed by Cutter et al. (2003) to construct an empirically derived index to measure social vulnerability ...


The Effects Of Urban Habitat Fragmentation On The Population Genetic Structure Of The Scincid Lizard Ctenotus Fallens, Jösef Krawiec 2011 Edith Cowan University

The Effects Of Urban Habitat Fragmentation On The Population Genetic Structure Of The Scincid Lizard Ctenotus Fallens, Jösef Krawiec

Theses : Honours

Species occurring in fragmented urban habitats often exhibit low genetic diversity which can be attributed to restricted gene flow and elevated levels of inbreeding. This can have serious implications for the survival of species especially when faced with additional pressures caused by urbanisation. The population genetic structure of the generalist skink Ctenotus fallens was examined within and among three urban vegetation remnants in the Perth metropolitan area in Western Australia, using both microsatellite and AFLP markers. Historic genetic connectivity between the populations of each remnant was shown as well as weak patterns of genetic differentiation which appeared to suggest isolation ...


Enhancing Automated Red Teaming With Monte Carlo Tree Search, Daniel Beard 2011 Edith Cowan University

Enhancing Automated Red Teaming With Monte Carlo Tree Search, Daniel Beard

Theses : Honours

This study has investigated novel Automated Red Teaming methods that support replanning. Traditional Automated Red Teaming (ART) approaches usually use evolutionary computing methods for evolving plans using simulations. A drawback of this method is the inability to change a team’s strategy part way through a simulation. This study focussed on a Monte-Carlo Tree Search (MCTS) method in an ART environment that supports re-planning to lead to better strategy decisions and a higher average score


Estimating Greenhouse Gas Emissions In Louisiana At The Parish Scale, Quang Tran 2011 Louisiana State University and Agricultural and Mechanical College

Estimating Greenhouse Gas Emissions In Louisiana At The Parish Scale, Quang Tran

LSU Master's Theses

The estimation of greenhouse gas (GHG) emissions and removals from the atmosphere at the county scale is an interest to many local decision makers and scientists looking to plan, track, mitigate, or reduce concentrations at the local or regional level. This thesis presents a new approach in downscaling state-level emissions to contiguous county levels using the state of Louisiana as an example. Here, we applied the volume- preserving principle in an attempt to improve existing methods and fully characterize accurate GHG emissions at the county (i.e., parish) level. All six “Kyoto” GHG emissions related to sources and sectors were ...


Surface-Initiated Polymerization As A Novel Strategy Towards Preparation Of Organic Semiconducting Polymer Thin Films, Euiyong Hwang 2011 Louisiana State University and Agricultural and Mechanical College

Surface-Initiated Polymerization As A Novel Strategy Towards Preparation Of Organic Semiconducting Polymer Thin Films, Euiyong Hwang

LSU Doctoral Dissertations

Organic semiconducting polymer thin films are core materials for organic electronics that are conventionally prepared by solution processing techniques. Despite having the advantage of easy and fast thin film manufacturing, solution techniques have intrinsic drawbacks, such as disordered and poor molecular organization in the film (often resulting in poor device performance), as well as insufficient stabilities of the films and resulting devices. To improve this situation, we designed a novel “bottom-up” fabrication of surface-immobilized organic semiconducting thin films through in situ polymerization. This new strategy will allow high degree of control over molecular organization which therefore results in improved free ...


Semiconducting Polymers And Block Copolymers Prepared By Chain-Growth Living Polymerization, JinWoo Choi 2011 Louisiana State University and Agricultural and Mechanical College

Semiconducting Polymers And Block Copolymers Prepared By Chain-Growth Living Polymerization, Jinwoo Choi

LSU Doctoral Dissertations

Organic semiconducting polymers are the unique materials that considered a basis for the next generation of electronic and optoelectronic applications. However, high device performance of semiconducting polymers strongly depends on their molecular structure and nanoscale organization. Therefore, it is an essential task to develop robust and versatile synthetic approaches to build such well-defined semiconducting polymer materials. This Ph.D. study aimed at design of state-of-the-art synthetic approaches towards organic semiconducting polymers via chain-growth living polymerization as well as development of polymer architectures which can self-organize into supramolecular nanoassemblies or allow external control of the polymer’s properties. First, we prepared ...


Integrated Modular Microfluidic System For Forensic Alu Dna Typing, Samuel Kimani Njoroge 2011 Louisiana State University and Agricultural and Mechanical College

Integrated Modular Microfluidic System For Forensic Alu Dna Typing, Samuel Kimani Njoroge

LSU Doctoral Dissertations

Driven by the numerous applications of genome-related research, fully integrated microfluidic systems have been developed that have advanced the capabilities of molecular and, in particular, genetic analyses. A brief overview on integrated microfluidic systems for DNA analysis is given in Chapter 1 followed by a report on micro-capillary electrophoresis (µCE) of Alu elements with laser-induced fluorescence (LIF) detection, in which the monomorphic Alu insertions on the X and Y chromosomes were utilized to detect male DNA in large female DNA background (Y: X = 1:19) without cell sorting prior to the determination. The polymorphic Alu loci with known restricted geographical ...


Summative Confidence, Paul Cristian Gugiu 2011 Western Michigan University

Summative Confidence, Paul Cristian Gugiu

Dissertations

Often the singular goal of an evaluation is to render a summative conclusion of merit, worth or feasibility that is based on multiple streams of multidimensional data. Exacerbating this difficulty, conducting evaluations in real-world settings often necessitates implementation of less than ideal study designs. This reality gets further complicated by the standard method for estimating the precision of results via the confidence interval (CI). Traditional CIs offer a limited approach for understanding the precision of a summative conclusion. This dissertation develops and presents a unified approach for the construction of a CI for a summative conclusion (SC).

This study derived ...

Commissioning Of The Helical Orbit Spectrometer: A New Device For Measuring Nuclear Reactions In Inverse Kinematics, Jonathan C. Lighthall 2011 Western Michigan University

Commissioning Of The Helical Orbit Spectrometer: A New Device For Measuring Nuclear Reactions In Inverse Kinematics, Jonathan C. Lighthall

Dissertations

The Helical Orbit Spectrometer (HELIOS) at Argonne National Laboratory is the first implementation of a radical new concept for measuring nuclear reactions. Direct nuclear transfer reactions are powerful tools for studying the properties of the atomic nucleus. A traditional example is the neutron-transfer reaction (d ,p), wherein an accelerated beam of deuterons d bombards a heavy target. The incoming deuteron transfers a neutron to the target nucleus and the outgoing proton p is detected to study the properties of the residual heavy nucleus. A new frontier of nuclear reaction studies involving short-lived exotic nuclei—which are unsuitable for use as ...


Glucosamine-Induced Insulin Resistance In Primary Rat Hepatocytes And The Role Of Selenium As An Insulin Mimetic, Sandhya N. Adiyodi Veetil 2011 Western Michigan University

Glucosamine-Induced Insulin Resistance In Primary Rat Hepatocytes And The Role Of Selenium As An Insulin Mimetic, Sandhya N. Adiyodi Veetil

Dissertations

Type 2 diabetes is mediated by insulin resistance, the inability of insulin to elicit a normal biological response in insulin responsive tissues. Several cellular models have been utilized to determine the mechanism of induction of insulin resistance but questions remain unanswered. One model, implicates the products of the Hexosamine Biosynthetic Pathway (HBP) in the induction of insulin resistance under hyperglycemia. The major end product of HBP, UDP-GlcNAc, is the substrate for O-GlcNAc transferase, an enzyme that catalyzes the O-GlcNAcylation of numerous proteins. This modification may play a role in induction of insulin resistance and thus needs to be evaluated in ...
