Audio Watermarking Using Transformation Techniques, Rajkiran Ravula Jan 2010

Audio Watermarking Using Transformation Techniques, Rajkiran Ravula

LSU Master's Theses

Watermarking is a technique, which is used in protecting digital information like images, videos and audio as it provides copyrights and ownership. Audio watermarking is more challenging than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. This thesis attempts to solve the quantization based audio watermarking technique based on both the Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). The underlying system involves the statistical characteristics of the signal. This study considers different wavelet filters and quantization techniques. A comparison is performed on diverge algorithms and audio signals to help examine the performance …

The State Of Education In Louisiana: Trend Analyses Of Student Achievement, Student Matriculation, And Student Behavior In The Accountability Era, Jonathon Anthony Szymanski Jan 2010

The State Of Education In Louisiana: Trend Analyses Of Student Achievement, Student Matriculation, And Student Behavior In The Accountability Era, Jonathon Anthony Szymanski

LSU Doctoral Dissertations

Public education has long been the subject of public discontent. Historical events such as the Soviet launch of Sputnik in 1957, the Civil Rights Movement of the 1950s and 1960s, and repeated media reports that U.S. students were outscored by students in many other countries on international tests each prompted federal and state legislation aimed to reform public education. Following a presentation of the relative standing of the United States on three international tests, the history of public schooling in six states, Texas, North Carolina, Kentucky, Maryland, Florida, and Louisiana, is discussed. The central focus of the study is student …

Studies Of Hydrophobic Organic Pollutant Interactions With Cyclodextrin: Implication For Groundwater Remediation, Heng Gao Jan 2010

Studies Of Hydrophobic Organic Pollutant Interactions With Cyclodextrin: Implication For Groundwater Remediation, Heng Gao

LSU Doctoral Dissertations

Henry’s Law constants of several common, subsurface hydrophobic organic pollutants (HOPs) including trichloroethylene (TCE), perchloroethylene (PCE) and benzene, toluene, ethylbenzene and o-xylene (BTEX), were measured over a range of temperatures (35, 45, 55 and 65°C) and cyclodextrin (CD) concentrations (0, 10, 20, 50 and 100 g L-1). In aqueous CD solutions, Henry’s constant values decrease by a power law relationship with increasing CD concentration due to an apparent solubility enhancement caused by HOP partitioning to the hydrophobic cavity of CD molecules. The temperature dependence of air-water partitioning under the influence of CD was well described by the van’t Hoff equation …

A Study Of Communication In Baby Boomers' Romantic Relationships And The Effects Of Their Children's Communication About The Relationships, Lois B. Nemetz Jan 2010

A Study Of Communication In Baby Boomers' Romantic Relationships And The Effects Of Their Children's Communication About The Relationships, Lois B. Nemetz

LSU Doctoral Dissertations

This study contributes to our knowledge of life-span communication by examining the communication of the Baby Boomer generation (born 1946-1964) as they re-enter the dating scene. Although Baby Boomers' early years of dating (the 1960's, 1970's, and 1980's) occurred in a time of new-found freedom, especially in sexual relationships, the experience of dating several decades later brings many complications due to aging and children. The intent of this study was not to generalize that all Baby Boomers would express the views stated in this study, but to show the complexity of this generation, and to present a theoretical framework for …

Effectiveness Of Forestry Best Management Practices In Minimizing Harvesting Impacts On Streamflow And Sediment Loading In Low-Gradient Headwaters Of The Gulf Coastal Plain, Kristopher Brown Jan 2010

Effectiveness Of Forestry Best Management Practices In Minimizing Harvesting Impacts On Streamflow And Sediment Loading In Low-Gradient Headwaters Of The Gulf Coastal Plain, Kristopher Brown

LSU Master's Theses

Few studies have examined the effectiveness of timber harvesting Best Management Practices (BMPs) in water quality protection of widely-spread, low-gradient, and highly intermittent headwaters on the Gulf Coastal Plain. Also, a spatial disparity exists between the plot-scale water quality benefits afforded by BMP implementation and the watershed-scale with which most watershed stewardship programs are managed. In this thesis research, paired-watershed and Before-After-Control-Impact (BACI) designs were utilized to quantify plot- and watershed-scale changes in streamflow, as well as baseflow and stormflow Total Suspended Sediment (TSS) concentration and yield for 27 months after clearcut harvesting with and without BMPs in a low-gradient, …

Primes Of The Form X² + Ny² In Function Fields, Piotr Maciak Jan 2010

Primes Of The Form X² + Ny² In Function Fields, Piotr Maciak

LSU Doctoral Dissertations

Let n be a square-free polynomial over F_q, where q is an odd prime power. In this work, we determine which irreducible polynomials p in F_q[x] can be represented in the form X^2+nY^2 with X, Y in F_q[x]. We restrict ourselves to the case where X^2+nY^2 is anisotropic at infinity. As in the classical case over Z, the representability of p by the quadratic form X^2+nY^2 is governed by conditions coming from class field theory. A necessary and almost sufficient condition is that the ideal generated by p splits completely in the Hilbert class field H of K=F_q(x,sqrt(-n)) for the …

Public Perception Of Wildfire Risk And Prescribed Burning In The Wildland/Urban Interface Of The Louisiana Florida Parishes, Charlotte Ann Gerald Jan 2010

Public Perception Of Wildfire Risk And Prescribed Burning In The Wildland/Urban Interface Of The Louisiana Florida Parishes, Charlotte Ann Gerald

LSU Master's Theses

Wildfire has been suppressed in the nation’s forests for over a hundred years. The accumulation of forest fuels over time has created an urgent need to reduce fuel loads to prevent catastrophic wildfires from occurring, not only in our wildlands, but also in our Wildland/Urban Interfaces (WUI’s). The residents who live within the WUI are particularly vulnerable to extreme wildfire events. As cities become more densely populated, increasing numbers of people are moving beyond the suburbs into the WUI. A complex matrix of structures and forested land, developing communities, and impinging forests exists within the WUI. This study utilized a …

Ferromagnetism And Transport In Diluted Magnetic Semiconductors, Abdolmadjid Nili Jan 2010

Ferromagnetism And Transport In Diluted Magnetic Semiconductors, Abdolmadjid Nili

LSU Doctoral Dissertations

This dissertation focuses on the study of ferromagnetism in Dilute Magnetic Semiconductors. To study these strongly correlated electronic systems, two non- perturbative techniques are used: the Dynamical Mean Field Approximation (DMFA) and the Dynamical Cluster Approximation (DCA). The model used for Dilute Magnetic Semiconductors (DMS) incorporates the strong spin-orbit couplings of the carrier holes as found in most III-V semiconductors doped with manganese such as Ga1-xMnxAs. Calculated within the DMFA, the spin-orbit coupling effects give rise to various interesting physics, primarily the anisotropic behavior of the impurity band that affect the charge transport properties in the …

New Age Control On A Mid-Shelf Grounding Event In Eastern Basin, Ross Sea, Amy Noelle Cone Jan 2010

New Age Control On A Mid-Shelf Grounding Event In Eastern Basin, Ross Sea, Amy Noelle Cone

LSU Master's Theses

It is widely accepted that the West Antarctic Ice Sheet (WAIS) was grounded at the continental shelf edge in Eastern Ross Sea during the Last Glacial Maximum (LGM), but the precise chronology is debated. Existing post-LGM ice retreat chronologies are considered suspect because nearly all have been developed using radiocarbon dating of acid-insoluble organics (AIO). Foraminifer tests yield more accurate radiocarbon dates than AIO because unlike loose sediment, foram tests are unlikely to be contaminated by allochthonous carbon, but unfortunately forams are sparse in Antarctic marine sediment cores. Here I utilized a new 3-D multibeam survey of a mid-continental-shelf grounding …

Synthesis Of Aza-Bridged Tetraphosphine Ligands For A Dirhodium Hydroformylation Catalyst, Scott Michael Boudreaux Jan 2010

Synthesis Of Aza-Bridged Tetraphosphine Ligands For A Dirhodium Hydroformylation Catalyst, Scott Michael Boudreaux

LSU Master's Theses

A novel tetraphosphine ligand rac-et,ph-P4 (et,ph-P4 = PEt2CH2CH2(Ph)PCH2P(Ph)CH2CH2PEt2) is used for the formation of a highly active and regioselective hydroformylation catalyst. The active catalytic species, Rh2H2(ƒÝ-CO)2(et,ph-P4)]2+, is formed in situ under H2/CO pressure. This is one of the most impressive examples of homobimetallic cooperativity in homogeneous catalysis. The fragmentation of this catalyst by CO has been investigated and confirmed by in situ NMR spectroscopic studies. A new tetraphosphine ligand rac-et,ph-P4-Ph (et,ph-P4-Ph = PEt2(o-C6H4)P(Ph)CH2(Ph)P(o-C6H4)PEt2) has been synthesized to combat this fragmentation problem. However, the inability to successfully separate the meso and racemic isomers of the ligand has led to more alteration …

Subgroups Of The Torelli Group, Leah R. Childers Jan 2010

Subgroups Of The Torelli Group, Leah R. Childers

LSU Doctoral Dissertations

Let Mod(Sg) be the mapping class group of an orientable surface of genus g, Sg. The action of Mod(Sg) on the homology of Sg induces the well-known symplectic representation:

Mod(Sg) ---> Sp(2g, Z).
The kernel of this representation is called the Torelli group, I(Sg).

We will study two subgroups of I(Sg). First we will look at the subgroup generated by all SIP-maps, SIP(Sg). We will show SIP(Sg) is not I(Sg) and is in fact an infinite index subgroup of I(Sg). We will also classify which SIP-maps are in the kernel of the Johnson homomorphism and Birman-Craggs-Johnson homomorphism.

Then we will …

Cross-Talk-Free Dual-Color Fluorescence Cross-Correlation Spectroscopy For High-Throughtput Screening, Wonbae Lee Jan 2010

Cross-Talk-Free Dual-Color Fluorescence Cross-Correlation Spectroscopy For High-Throughtput Screening, Wonbae Lee

LSU Doctoral Dissertations

High throughput processing of chemical/biochemical information is critical in many areas, such as genome sequencing, drug discovery and clinical diagnostics. Integral to collecting information at high rates with the necessary throughput is the development of systems that can not only monitor the results with high precision and accuracy, but also prepare and process samples prior to the analytical measurement. To achieve the required throughput, we have conducted work directed toward developing a system that provides detection sensitivity at the single-molecule detection (SMD) level. The research was first focused on the development of a sensitive strategy for the detection of proteins …

Progenitor scenarios for short gamma-ray bursts (short GRBs) include coalescenses of two neutron stars or a neutron star and black hole, which would necessarily be accompanied by the emission of strong gravitational waves. We present a search for these known gravitational-wave signatures in temporal and directional coincidence with 22 GRBs that had sufficient gravitational-wave data available in multiple instruments during LIGO's fifth science run, S5, and Virgo's first science run, VSR1. We find no statistically significant gravitational-wave candidates within a [ - 5, + 1)s window around the trigger time of any GRB. Using the Wilcoxon-Mann-Whitney U-test, we find no …

We present a search for gravitational waves from 116 known millisecond and young pulsars using data from the fifth science run of the LIGO detectors. For this search, ephemerides overlapping the run period were obtained for all pulsars using radio and X-ray observations. We demonstrate an updated search method that allows for small uncertainties in the pulsar phase parameters to be included in the search. We report no signal detection from any of the targets and therefore interpret our results as upper limits on the gravitational wave signal strength. The most interesting limits are those for young pulsars. We present …

Socially Induced Synchronization Of Every-Other-Day Egg Laying In A Seabird Colony, Shandelle M. Henson, James L. Hayward, J. M. Cushing, Joseph C. Galusha Jan 2010

Socially Induced Synchronization Of Every-Other-Day Egg Laying In A Seabird Colony, Shandelle M. Henson, James L. Hayward, J. M. Cushing, Joseph C. Galusha

Faculty Publications

Spontaneous oscillator synchrony has been documented in a wide variety of electrical, mechanical, chemical, and biological systems, including the menstrual cycles of women and estrous cycles of Norway Rats (Rattus norvegicus). In temperate regions, many colonial birds breed seasonally in a time window set by photoperiod; some studies have suggested that heightened social stimulation in denser colonies can lead to a tightened annual reproductive pulse. It has been unknown, however, whether the analog of menstrual synchrony occurs in birdsthat is, whether avian ovulation cycles can synchronize on a daily timescale within the annual breeding pulse. We report every-other-day clutch-initiation and …

The Effect Of Athletic Participation On Academic Achievement For High School Seniors In Eastern Tennessee, David Andrew Gorman Jan 2010

The Effect Of Athletic Participation On Academic Achievement For High School Seniors In Eastern Tennessee, David Andrew Gorman

Doctoral Dissertations and Projects

This causal-comparative study with a narrative component investigated the effect athletic participation on the academic achievement of senior student-athletes and non-athletes who attended three public high schools in Eastern Tennessee. The impetus for the study was the conflicting research as it relates to the impact athletics participation had on academic success at the college and high school levels. Through student athlete and non-athlete comparisons of ACT scores and GPAs, the researcher found athletic participation did not affect academic achievement for high school seniors who graduated in 2009 from the three target high schools when compared to non-athletes. However, statistically significant …

Investigation And Modeling Of Viscoelastic Moduli For Multilayered Polymeric Systems Using High Frequency Ultrasonic Waves, Todd Mathew Fernandez Jan 2010

Investigation And Modeling Of Viscoelastic Moduli For Multilayered Polymeric Systems Using High Frequency Ultrasonic Waves, Todd Mathew Fernandez

Theses

Mechanical characterization of both the bulk and individual layer properties of layered polymer stacks provides important information for their use in novel applications. A single technique to measure both the bulk and layer properties is atempted. Ultrasonic testing provides an opportunity to determine the mechanical characteristics for layered samples in the form of the complex mechanical moduli. These moduli express the viscoelastic properties of the materials. Using ultrasound, this can be done for the bulk and the layers in a single test. With ultrasound, the ability to determine the complex moduli in single layers has been demonstrated. The moduli were …

A Class Of Discontinuous Petrov–Galerkin Methods. Ii. Optimal Test Functions, Leszek Demkowicz, Jay Gopalakrishnan Jan 2010

A Class Of Discontinuous Petrov–Galerkin Methods. Ii. Optimal Test Functions, Leszek Demkowicz, Jay Gopalakrishnan

Mathematics and Statistics Faculty Publications and Presentations

We lay out a program for constructing discontinuous Petrov–Galerkin (DPG) schemes having test function spaces that are automatically computable to guarantee stability. Given a trial space, a DPG discretization using its optimal test space counterpart inherits stability from the well posedness of the undiscretized problem. Although the question of stable test space choice had attracted the attention of many previous authors, the novelty in our approach lies in the fact we identify a discontinuous Galerkin (DG) framework wherein test functions, arbitrarily close to the optimal ones, can be locally computed. The idea is presented abstractly and its feasibility illustrated through …

Multigrid In A Weighted Space Arising From Axisymmetric Electromagnetics, Dylan M. Copeland, Jay Gopalakrishnan, Minah Oh Jan 2010

Multigrid In A Weighted Space Arising From Axisymmetric Electromagnetics, Dylan M. Copeland, Jay Gopalakrishnan, Minah Oh

Mathematics and Statistics Faculty Publications and Presentations

Consider the space of two-dimensional vector functions whose components and curl are square integrable with respect to the degenerate weight given by the radial variable. This space arises naturally when modeling electromagnetic problems under axial symmetry and performing a dimension reduction via cylindrical coordinates. We prove that if the original three-dimensional domain is convex then the multigrid Vcycle applied to the inner product in this space converges, provided certain modern smoothers are used. For the convergence analysis, we first prove several intermediate results, e.g., the approximation properties of a commuting projector in weighted norms, and a superconvergence estimate for a …

Investigating Further Preservice Teachers’ Conceptions Of Multidigit Whole Numbers: Refining A Framework, Eva Thanheiser Jan 2010

Investigating Further Preservice Teachers’ Conceptions Of Multidigit Whole Numbers: Refining A Framework, Eva Thanheiser

Mathematics and Statistics Faculty Publications and Presentations

This study was designed to investigate preservice elementary school teachers’ (PSTs’) responses to written standard place-value-operation tasks (addition and subtraction). Previous research established that PSTs can often perform but not explain algorithms and provided a four-category framework for PSTs’ conceptions, two correct and two incorrect. Previous findings are replicated for PSTs toward the end of their college careers, and two conceptions are further analyzed to yield three categories of incorrect views of regrouped digits: (a) consistently as 1 value (all as 1 or all as 10), (b) consistently within but not across contexts (i.e., all as 10 in addition but …

Community Development For A White City: Race Making, Improvementism, And The Cincinnati Race Riots And Anti-Abolition Riots Of 1829, 1836, And 1841, Silas Niobeh Crowfoot

Dissertations and Theses

This project is an historical ethnography and a cultural history of the anti-black race riots and anti-abolition riots in Cincinnati, Ohio, in 1829, 1836, and 1841. It is also a case history in an urban and commercial/early industrial context of the idea that violent social practices such as riots, as well as law and the customary practices of everyday living, are deployed as race making technologies, actually constructing racial categories. By extending this constructivist concept to the conversion of space to place through the human ascription of meaning, this study also examines racial violence as a strategy for place making …

Medical Image Segmentation Using A Genetic Algorithm, Payel Ghosh Jan 2010

Medical Image Segmentation Using A Genetic Algorithm, Payel Ghosh

Dissertations and Theses

Advances in medical imaging technology have led to the acquisition of large number of images in different modalities. On some of these images the boundaries of key organs need to be accurately identified for treatment planning and diagnosis. This is typically performed manually by a physician who uses prior knowledge of organ shapes and locations to demarcate the boundaries of organs. Such manual segmentation is subjective, time consuming and prone to inconsistency. Automating this task has been found to be very challenging due to poor tissue contrast and ill-defined organ/tissue boundaries. This dissertation presents a genetic algorithm for combining representations …

The Micropivot : An Integrated Particle Image Velocimeter And Optical Tweezers Instrument For Microscale Investigations, Nathalie Neve De Mevergnies Jan 2010

The Micropivot : An Integrated Particle Image Velocimeter And Optical Tweezers Instrument For Microscale Investigations, Nathalie Neve De Mevergnies

Dissertations and Theses

This dissertation describes the development of a device capable of suspending a microscale object in a controlled flow. The uPIVOT is a system integrating two laser-based techniques: micron particle image velocimetry (uPIV) and optical tweezers (OT). The OT allows the suspension and manipulation of micron-sized objects such as microspheres or biological cells. uPIV provides imaging of the suspended object and velocity measurements from which fluid induced stresses can be determined. Using this device, we measured fluid velocities around an optically suspended polystyrene microsphere (an experimental first) and studied the interaction between two particles suspended in a uniform flow. The results …

Investigating Freeway Speed-Flow Relationships For Traffic Assignment Applications, Meead Saberi Kalaee Jan 2010

Investigating Freeway Speed-Flow Relationships For Traffic Assignment Applications, Meead Saberi Kalaee

Dissertations and Theses

Developments in high resolution traffic sensors over the past decades are providing a wealth of empirical speed-flow data. Travel demand models use speed-flow relationships to assign traffic flows to network links. However, speed-flow relationships have not been revalidated against new detailed traffic sensor data. Therefore, it is necessary to revisit speed-flow relationships based on actual measured conditions on network links rather than assuming constant speed-flow relationships over entire highway network systems. Speed-flow relationships have been particularly difficult to calibrate and estimate when traffic volumes approach capacity, i.e. when the v/c ratio approaches one. This thesis empirically evaluates the speed-flow relationships …

Northeast Asia And The Avoidance Of A Nuclear Arms Race, Samuel Fogleman Jan 2010

Northeast Asia And The Avoidance Of A Nuclear Arms Race, Samuel Fogleman

Dissertations and Theses

Since the end of the Sino-Vietnamese War in 1979, Northeast Asia and its comprising countries have avoided international conflict as well as any regional set has done over the past few decades. The absence of nuclear weapons among Japan, South Korea, and Taiwan, in particular, is striking, given their technological and scientific capabilities. Though each of those countries has come close at times to developing their own nuclear weapons, one factor or another contributed to the failure of those upstart programs. The United States has played a significant role in all of them. Still, other factors remain. The purpose of …

Dissertations and Theses

Gender equity has been a national and global aim for over half a century (Ceci & Williams, 2007; National Center for Education Statistics, 2003; National Science Board, 2008). While gains have been made, one area where inequity remains is spatial reasoning ability, where a large gender gap in favor of males has persisted over the years (Else-Quest, Linn, & Shibley Hyde, 2010; National Science Board, 2008; Ruble, Martin, & Berenbaum, 2006). This gender gap in spatial reasoning has had substantial societal impact on the career interests of females in areas of Science, Technology, Engineering, and Math (STEM), contributing to the …
