Koszul Duality For Multigraded Algebras, Fareed Hawwa
Koszul Duality For Multigraded Algebras, Fareed Hawwa
LSU Doctoral Dissertations
Classical Koszul duality sets up an adjoint pair of functors establishing an equivalence of categories. The equivalence is between the bounded derived category of complexes of graded modules over a graded algebra and the bounded derived category of complexes of graded modules over the quadratic dual graded algebra. This duality can be extended in many ways. We consider here two extensions: first we wish to allow a multigraded algebra, meaning that the algebra can be graded by any abelian group (not just the integers). Second, we will allow filtered algebras. In fact we are considering filtered quadratic algebras with an …
Staging Polemics: Charles Palissot, Voltaire, And The "Theatrical Event" In Eighteenth-Century France, Logan James Connors
Staging Polemics: Charles Palissot, Voltaire, And The "Theatrical Event" In Eighteenth-Century France, Logan James Connors
LSU Doctoral Dissertations
This dissertation explores the exciting world of eighteenth-century French dramatic writing, performance and criticism from the point of view of the theatrical spectator. Instead of focusing on one single genre or writer, I assemble the textual creation, performance, and criticism of certain “polemical” plays into what I term a “theatrical event.” This optic provides a holistic vision of theater and an accurate view of how drama underwent noticeable change due to playwrights’ political associations, public reactions to performance, and the emerging power of the periodical press. In sum, this project differs from previous studies by focusing on the increasing rhetorical …
Dimer Models For Knot Polynomials, Moshe Cohen
Dimer Models For Knot Polynomials, Moshe Cohen
LSU Doctoral Dissertations
A dimer model consists of all perfect matchings on a (bipartite) weighted signed graph, where the product of the signed weights of each perfect matching is summed to obtain an invariant. In this paper, the construction of such a graph from a knot diagram is given to obtain the Alexander polynomial. This is further extended to a more complicated graph to obtain the twisted Alexander polynomial, which involved "twisting" by a representation. The space of all representations of a given knot complement into the general linear group of a fixed size can be described by the same graph. This work …
Experimental And Analytical Study Of The Surface Texturing Enhanced Lubrication Elements, Yifan Qiu
Experimental And Analytical Study Of The Surface Texturing Enhanced Lubrication Elements, Yifan Qiu
LSU Doctoral Dissertations
Surface texturing is a method that modifies the frictional surface of a nominally flat tribocomponent by shallow patterns. It is found that with added patterns to the surface of a mechanical face seal or thrust bearing, their tribological performance improves, i.e. both friction and wear rate decrease. The current research concentrates on the analysis of hydrodynamic effect responsible for the performance enhancement of the spiral groove patterns and dimples on mechanical seal-like structures and the experimental evaluation of the tribological behavior of these structures. Surface textures considered are: dimple texture and spiral groove pattern. In the research on the dimple …
Maladies Of Modernity: Scientism In Politics, David Nathan Whitney
Maladies Of Modernity: Scientism In Politics, David Nathan Whitney
LSU Doctoral Dissertations
This dissertation explores the complex relationship between science and politics. More specifically, it focuses on the problem of scientism. Features of scientism include the dogmatic faith in the methods of the natural sciences (and the accompanying assumption that those methods can be successfully imported into the social sciences), a materialistic worldview, the rejection of the bios theoretikos, the prohibition of philosophical questions, and an emphasis on immanent fulfillment through the power of science. I seek to demonstrate that scientism is intellectually impoverishing and politically dangerous. Given the lack of full-length studies on the subject, I trace the development of scientism …
Integration Of Paleotempestology With Coastal Risk And Vulnerability Assessment: Case Studies From The Dominican Republic And Nicaragua, Devyani Kar
LSU Doctoral Dissertations
Hurricanes account for a significant portion of damages, injuries, and fatalities in the Caribbean. The Dominican Republic has had 3 major hurricane strikes in this century resulting in loss of lives for thousands of people and billions of US $ in economic loss. Major hurricanes had been relatively infrequent in north-eastern Nicaragua’s modern history until Hurricane Felix, a Category 5 storm, made landfall in the north-east in 2007. It caused 130 confirmed deaths and brought devastation to many villages. These events highlight a need for re-evaluation of hurricane risk based on a more comprehensive and long-term hurricane history. Using paleotempestological …
Data Transfer Scheduling With Advance Reservation And Provisioning, Mehmet Balman
Data Transfer Scheduling With Advance Reservation And Provisioning, Mehmet Balman
LSU Doctoral Dissertations
Over the years, scientific applications have become more complex and more data intensive. Although through the use of distributed resources the institutions and organizations gain access to the resources needed for their large-scale applications, complex middleware is required to orchestrate the use of these storage and network resources between collaborating parties, and to manage the end-to-end processing of data. We present a new data scheduling paradigm with advance reservation and provisioning. Our methodology provides a basis for provisioning end-to-end high performance data transfers which require integration between system, storage and network resources, and coordination between reservation managers and data transfer …
Augmented Breast Tumor Classification By Perfusion Analysis, Bruce Yu-Sun Lin
Augmented Breast Tumor Classification By Perfusion Analysis, Bruce Yu-Sun Lin
LSU Doctoral Dissertations
Magnetic resonance and computed tomography imaging aid in the diagnosis and analysis of pathologic conditions. Blood flow, or perfusion, through a region of tissue can be computed from a time series of contrast-enhanced images. Perfusion is an important set of physiological parameters that reflect angiogenesis. In cancer, heightened angiogenesis is a key process in the growth and spread of tumorous masses. An automatic classification technique using recovered perfusion may prove to be a highly accurate diagnostic tool. Such a classification system would supplement existing histopathological tests, and help physicians to choose the most optimal treatment protocol. Perfusion is obtained through …
Exploring The Impacts Of Wiki Collaborative Technologies Within The English Writing Environment, Valarie D. Dufrene
Exploring The Impacts Of Wiki Collaborative Technologies Within The English Writing Environment, Valarie D. Dufrene
LSU Doctoral Dissertations
The use of technology in the writing classroom has been a staple since the early-1990’s when the personal computer made its way onto the desks of teachers and students across America. Since that time, the challenge has been for educators to incorporate the most recent technologies in an effort to stimulate student writing. This study examined the effects the use of a web-based wiki technology can have on the writings of high school students. The primary goal of this study was to explore how the web-based collaborative technology in Google Docs and used in a secondary English IV classroom can …
Reflections On Teaching: Dwelling In A Third Space, Sean William Buckreis
Reflections On Teaching: Dwelling In A Third Space, Sean William Buckreis
LSU Doctoral Dissertations
What does it mean to teach well? What does it mean to be a good teacher? These are questions that have been asked for hundreds if not thousands of years; yet, an unequivocal answer has not been reached. Drawing on Thomas Kuhn’s (1962/1996) concept of a paradigm, it is easy to see that the field of curriculum is anything but paradigmatic. Competing philosophical, psychological, and sociological schools of thought, for example, all support differing ideas of what “good teaching” looks like, and teacher education programs often reflect this diversity of thought. The situation does not end at the borders of …
The Development Of Primary And Secondary Memory And Their Relationship To Fluid Intelligence, Sharon Diane Eaves
The Development Of Primary And Secondary Memory And Their Relationship To Fluid Intelligence, Sharon Diane Eaves
LSU Doctoral Dissertations
Researchers have been able to link working memory to many important cognitive abilities throughout the life span. Two of the unanswered questions about working memory are what cognitive processes function during working memory task performance and how do these processes directly relate to intelligence? A recent model (Unsworth & Engle, 2006) suggested that performance on working memory tasks was determined by two abilities: the capacity of primary memory and the ability to efficiently retrieve information from secondary memory. In the current study, we extended Unsworth and Engle’s (2006) methodology to include two groups of children (ages 8-9 and 10-11). Our …

This study was completed in two phases: evaluation of existing middle school summer engineering program curriculum for best practices and development of innovative curriculum and expert evaluation of the innovative curriculum. Three existing programs from across the country participated in this study. Five engineering …
Sonata No.1 For Violin And Piano, Op. 80,By Sergei Prokofiev: A Guide To Interpretation, Boris Blagoev
Sonata No.1 For Violin And Piano, Op. 80,By Sergei Prokofiev: A Guide To Interpretation, Boris Blagoev
LSU Doctoral Dissertations
Sergei Prokofiev was an extremely prolific composer whose career brought him success throughout Europe and the U. S. as well as Russia and the Soviet Union. He wrote for nearly every genre, and his most popular works today include operas, ballets, symphonies, and concertos. As a pianist, most of the concertos and sonatas that Prokofiev wrote were for the piano. However, his contributions to the violin repertoire are significant. Prokofiev wrote two concertos and two sonatas for solo violin. Of these, Sonata No. 1 for Violin and Piano, Op. 80 is unique for many reasons. The piece took Prokofiev eight …
Joep Franssens' Harmony Of The Spheres: A Conductor's Analysis, David Andrew Hobson
Joep Franssens' Harmony Of The Spheres: A Conductor's Analysis, David Andrew Hobson
LSU Doctoral Dissertations
Harmony of the Spheres is Dutch composer Joep Franssens’ most extensive choral work to date, exhibiting a substantial possibility to enter the international repertoire as a complete work; however, several of the movements can stand alone effectively. Presented in five symmetrically conceived movements, Franssens scores the piece for SSAATTBB chorus with only the addition of full string orchestra for Movement III. The composition seeks to explore profound connections between science, music, philosophy, religion, and human relationships, intertwining excerpts from Benedict de Spinoza’s magnum opus, Ethica, allusions to the ancient idea of the music of the spheres, and European minimalism. Franssens …
Characterization Of Rock/Fluids Interactions At Reservoir Conditions, Dayanand Saini
Characterization Of Rock/Fluids Interactions At Reservoir Conditions, Dayanand Saini
LSU Doctoral Dissertations
In this study, interfacial phenomena of spreading, wettability, and rock/oil adhesion interactions in complex rock/oil/water systems were characterized at reservoir conditions of elevated pressures and temperatures. Capabilities of both ambient and reservoir condition optical cells were used for measuring the oil/water interfacial tension and dynamic (the water-receding and the water-advancing) contact angles for various complex rock/oil/water systems. Well known sessile oil drop volume alteration method was successfully used in this study for evaluating the applicability of the modified Young’s equation for characterizing the line tension in complex rock/oil/water systems at reservoir conditions. This appears to be first time when rock/fluids …
Dissolution Of Chitosan In Ionic Liquids For Acylation Chemistry And Formation Of Cellulose-Chitosan Blends, Cristina Stefanescu
Dissolution Of Chitosan In Ionic Liquids For Acylation Chemistry And Formation Of Cellulose-Chitosan Blends, Cristina Stefanescu
LSU Doctoral Dissertations
Dissolution of chitosan in ionic liquids was accomplished. It has been shown that 1-butyl-3-methylimidazolium acetate (BMIMAc) is a better solvent than 1-butyl-3-methylimidazolium chloride (BMIMCl). Dissolution of chitosan in BMIMCl required a prior regeneration of chitosan from 1% acetic acid solution. In the case of BMIMAc, both dried chitosan and regenerated chitosan from acetic acid solution have been dissolved in a relatively short amount of time. While concentrations up to 2 wt% of chitosan in BMIMCl could be obtained, concentrations of 10 wt % of chitosan in BMIMAc were realized. Homogeneous phthalation and benzoylation of chitosan were achieved in these ionic …

Iron (Iii) Oxide And Copper (Ii) Oxide Mediated Formation Of Pcdd/Fs From Thermal Degradation Of 2-Mcp And 1,2-Dcbz, Shadrack Kirwa Nganai
LSU Doctoral Dissertations
Formation of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) which occurs inexorably from most thermal and combustion processes constitutes a major toxic component of environmental pollutants. Generally, it is well established that transition metal-mediated reactions account for the majority of PCDD/F emissions from combustion sources. Specifically, both copper and iron ions, which occur abundantly in combustion generated particulate matter, are considered probably the most active in promoting PCDD/F formation typically in the low temperature post-combustion zone and flue gas pollution control devices. It has also been demonstrated that chlorinated phenols are key intermediates in essentially all pathways of PCDD/F formation. Chlorinated benzenes …
Ospc In The Pathogenesis Of Borrelia Burgdorferi, Sunita V. Seemanapalli
Ospc In The Pathogenesis Of Borrelia Burgdorferi, Sunita V. Seemanapalli
LSU Doctoral Dissertations
Lyme disease is a multisystem disorder caused by the tick vector Borrelia burgdorferi. During its life cycle between the tick vector and the mammalian host, Borrelia up- and down-regulates the expression of its surface lipoproteins. Of its many surface lipoproteins, the Outer surface protein C (OspC) is crucial for initial mammalian infection. OspC has a common role shared with other lipoproteins of protection against host innate defences and a unique function in facilitating the dissemination of B. burgdorferi in the murine host. The structure of OspC was solved in 2001 and the lipoprotein was found to be predominantly alpha-helical with …

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 …

The GEE is a high-stakes test that is administered to high school students in Louisiana. Students must pass specific portions of the test to obtain a diploma. Academic achievement data on the GEE was obtained from the Louisiana Department of Education. The sample for the study was all 10th and 11th grade students enrolled …
Quantifying The Impact Of Data Quality On Searches For Gravitational Waves From Binary Coalescing Systems With Ligo, Jacob Peter Slutsky
Quantifying The Impact Of Data Quality On Searches For Gravitational Waves From Binary Coalescing Systems With Ligo, Jacob Peter Slutsky
LSU Doctoral Dissertations
Gravitational waves are ripples in space-time itself, predicted by Einstein's General theory of relativity, which propagate at the speed of light and are not scattered or extinguished by passing through matter almost at all. In particular, the gravitational waves from the coalescences of binary systems of compact objects, such as neutron stars and black holes, are exciting prospects for observation. The Laser Interferometer Gravitational-wave Observatory experiment intends to make the _x000C_first direct measurement of gravitational waves, and use the results to uncover new astrophysics. These observations will not be limited by extinction from dust and gas, and will probe astrophysical …
Model-Based Nonlinear Control Of Active Tilting-Pad Bearings, An Wu
Model-Based Nonlinear Control Of Active Tilting-Pad Bearings, An Wu
LSU Doctoral Dissertations
A promising mechanical bearing candidate for active operation is the tilting-pad bearing. The proposed active tilting-pad bearing has linear actuators that radially translate each pad. The use of feedback control in determining the actuator forces allows for the automatic, continuous adjustment of the pad position during the operation of the rotating machine. In the first part of the dissertation, we develop a nonlinear dynamic model of the active bearing system. The hydrodynamic force produced by the fluid film is modeled as a nonlinear, squeeze-film damper plus repellent spring. A model-based nonlinear controller is then designed to exponentially regulate the rotor …
Primes Of The Form X² + Ny² In Function Fields, Piotr Maciak
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 …
Ferromagnetism And Transport In Diluted Magnetic Semiconductors, Abdolmadjid Nili
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 …
Quantum Light For Quantum Technologies, William Nicholas Plick
Quantum Light For Quantum Technologies, William Nicholas Plick
LSU Doctoral Dissertations
In this thesis we will theoretically investigate three potentially useful physical systems, after first developing the theoretical framework necessary for studying them. First, we will study the multiphoton absorption properties of maximally path entangled number (N00N) states. This is directly relevant to quantum lithography, and beating the Rayleigh diffraction limit. Next, we will develop a new scheme for quantum interferometry: dubbed coherent-light boosted super-sensitive quantum interferometry, which has the potential to reach below the shot noise limit for high photon fluxes, and requires no esoteric detection protocol, or technological elements that have yet to be developed. Finally we propose a …
Computer Simulation Of Ion-Induced Nucleation In The Presence Of Single Ions And Ion Pairs, Samuel Keasler
Computer Simulation Of Ion-Induced Nucleation In The Presence Of Single Ions And Ion Pairs, Samuel Keasler
LSU Doctoral Dissertations
Atmospheric aerosol particles play an important role in climate and human health. Despite their importance, the mechanisms of their formation are still poorly understood. Ion-induced nucleation may play a role in the process, but details are lacking about how the nucleation rate depends on the size, charge, and number of ions in the cluster. In order to better understand the role that ions might play in new particle formation, we have performed a series of AVUS-HR simulations of the water nucleation in the presence of both single ions and ion pairs. These simulations have shown that the location of the …
Retention Of Students In A Diploma Nursing Program In The Southern United States, Carol Ann Tingle
Retention Of Students In A Diploma Nursing Program In The Southern United States, Carol Ann Tingle
LSU Doctoral Dissertations
Registered Nurses comprise the largest group of healthcare professionals in the United States, and forecasts predict a nursing shortage of epic proportions on the horizon. Significant factors include approaching retirement of Baby Boomer RNs, increased demand for care for aging Baby Boomers in the population, approaching retirement of nurse educators, and rejection of qualified applicants secondary to enrollment restrictions in nursing programs. Nursing student attrition further contributes to the pending shortage. Successful retention programs promote best-practice utilization of scarce resources. Understanding student characteristics serves as a basis for effective selection and retention programs. This study described characteristics of nursing students …
