Blind Multiridge Detection And Reconstruction Using Ultrasonic Signals, Rekha Katragadda

LSU Master's Theses

Time-frequency signal analysis has been widely applied in the modern radar, acoustic, sonar and ultrasonic signal processing techniques. Recently, the nondestructive testing (NDT) techniques via the ultrasonic instrumentation have shown the striking capability of the quality control for the material fabrication industry. In this thesis, we first provide a general mathematical model for the ultrasonic signals collected by pulse-echo sensors and then design a totally blind, novel, signal processing NDT technique relying on neither a priori signal information nor any manual effort. The signature signal can be blindly extracted by using the automatic optimal frame size selection for further modeling …

Active Security Mechanisms For Wireless Sensor Networks And Energy Optimization For Passive Security Routing, Lydia Ray

LSU Doctoral Dissertations

Wireless sensor networks consisting of numerous tiny low power autonomous sensor nodes provide us with the remarkable ability to remotely view and interact with the previously unobservable physical world. However, incorporating computation intensive security measures in sensor networks with limited resources is a challenging research issue. The objective of our thesis is to explore different security aspects of sensor networks and provide novel solutions for significant problems. We classify security mechanisms into two categories - active category and passive category. The problem of providing a secure communication infrastructure among randomly deployed sensor nodes requires active security measurements. Key pre-distribution is …

Physical Model Experiments Of The Gas-Assisted Gravity Drainage Process, Amit P. Sharma

LSU Master's Theses

The displacement of oil by gas injection in oil reservoirs is an attractive method of improved oil recovery. Commercial gravity-stable gas injection projects have demonstrated excellent recoveries; however, their application has been limited to dipping reservoirs and pinnacle reefs. Horizontal gas floods and the water alternating gas (WAG) processes, practiced in horizontal type reservoirs, have yielded less than satisfactory recoveries of 5-10%. The Gas Assisted Gravity Drainage (GAGD) Process being developed at LSU extends the concept of gravity-stable gas floods to horizontal type reservoirs to improve volumetric sweep and oil recovery. This experimental study consists of a series of visual …

The purpose of this paper is to provide a stylistic analysis that contrasts five Thomas Hardy settings by Gerald Finzi with five settings by John Ireland. In order to investigate the apparent intuitiveness with which both Ireland and Finzi approached Thomas Hardy’s poetry, biographical information is provided to reveal similarities in the backgrounds of each composer. Highlighted are the compositional techniques and text setting ideologies each composer utilized when facing the challenges and eccentricities of Hardy’s poetry. A brief discussion on the philosophical foundations of Thomas Hardy’s poetry is also included. The repertoire discussed within are the settings Summer Schemes, …

Hospital Chaplaincy Under The Hipaa Privacy Rule: Health Care Or "Just Visiting The Sick?", Stacey A. Tovino

Scholarly Works

Approximately seventy-nine percent of Americans believe that praying can help people recover from illness, injury or disease, and nearly seventy-seven percent of American patients would like spiritual issues discussed as part of their care. Despite Americans' strong beliefs in the health-related benefits of religious and spiritual practices and traditions, the preamble to the federal Department of Health and Human Services' ("HHS") health information privacy rule (the "Privacy Rule") explains that health care "does not include methods of healing that are solely spiritual" (the "preamble"). The preamble concludes that, "clergy or other religious practitioners that provide solely religious healing services are …

The Literary Frontier: Creating An American Nation (1820-1840), Tena Lea Helton

LSU Doctoral Dissertations

From the perspective of the twenty-first century, it might be easy to dismiss frontier literature as a minor historical anomaly, as a descriptor limited to setting, or as an insignificant variation from a country struggling to reach the heights of British fictional “norms.” However, when American literature began to flourish in the 1820s, it was primarily a literature of the frontier. Examining what this frontier quality means for literary elements beyond setting, such as narrative voice, textual structure, and genre, more clearly explains the importance of the frontier to literary nation-building. After all, the literary frontier ranged across literary genres, …

Conceptualizing Describing And Contrasting School Cultures: A Comparative Case Study Of School Improvement Processes, La Tefy Schoen

LSU Doctoral Dissertations

What is school culture? How can it be measured, described and contrasted? Is school culture related to school improvement? This dissertation investigates school culture and its relationship to school improvement. The study is organized into three phases and employs a mixed methods approach to study the cultures of three pairs of matched schools over a 15 month period. Phase I consists of a multi-disciplinary literature review across the fields of psychology, sociology, business management, anthropology, and educational administration. This process resulted in the development of a new conceptualization of school culture based on merging complementary theories. As defined here school …

Technological Stressors Of Louisiana Baccalaureate Nurse Educators, Mary Ann Stark Burke

LSU Doctoral Dissertations

Computers are now a part of everyday life, with the majority of daily activities revolving around the use of a computer. The concept of technostress was first introduced in the 1980's when computers became more prevalent in the business and academic world. Nurse educators have been impacted by the rapid changes in technology in recent years. A review of the literature revealed no research studies that have been conducted to investigate the incidence of technological stress among nurse educators. Therefore, the purpose of this descriptive-correlational study was to describe the technological stressors that Louisiana baccalaureate nurse educators experienced while teaching …

Virtual Property, Joshua Fairfield

Articles by Maurer Faculty

This article explores three new concepts in property law. First, the article defines an emerging property form - virtual property - that is not intellectual property, but that more efficiently governs rivalrous, persistent, and interconnected online resources. Second, the article demonstrates that the threat to high-value uses of internet resources is not the traditional tragedy of the commons that results in overuse. Rather, the naturally layered nature of the internet leads to overlapping rights of exclusion that cause underuse of internet resources: a tragedy of the anticommons. And finally, the article shows that the common law of property can act …

Seasonal Abundance And Detection Of West Nile Virus In Ceratopogonids (Diptera: Ceratopogonidae) In East Baton Rouge Parish, Louisiana, Isidra Joselina Sabio

LSU Master's Theses

The seasonal abundance and species composition of ceratopogonids (Diptera: Ceratopogonidae) in East Baton Rouge parish was described from light trap collections at 15 sites. A total of 4,968 collections were processed, and 48,667 ceratopogonids were collected from 20 November, 2002 through 25 November, 2004. Three genera of ceratopogonids (Forcipomyia Meigen, Atrichopogon Kieffer, and Culicoides Latrielle) and a total of 18 species of the genus Culicoides were identified. Ceratopogonids had distinctive spring and fall population peaks. Ceratopogonids were collected in every month during the study, with the exception of February 2004. These results suggest that certain species of Culicoides may …

La Grande Force Est Le D'Sir: Guillaume Apollinaire's Rewriting Of Merlin's Mother And The Dame Du Lac In L'Enchanteur Pourrissant, Allison Bateman Roark

LSU Doctoral Dissertations

This dissertation analyzes Guillaume Apollinaire's rewriting of Merlin's mother and the Dame du Lac in L'Enchanteur pourrissant as a commentary on writing. I consider Merlin's state in the tomb as an effect of his desire for the Dame du Lac and relate this to the poet's relationship to writing, which is the result of his desire for a unity of expression -- to express what can be designated in the text, but not directly communicated in its totality through language. There is always something missing from any writing, but the very absence of meaning influences poetic production by encouraging attempts …

Dental Evidence For Division Of Labor Among The Prehistoric Ipiutak And Tigara Of Point Hope, Alaska, Felicia Madimenos

LSU Master's Theses

Among archaeological specimens, teeth can provide insight into the behaviors and cultural practices of a population. Inuit specimens are ideal for studying dentition because of the unique way teeth are used as tools. The prehistoric Ipiutak (ca.100 B.C. – A.D. 500) and Tigara (ca. A.D. 900 –1700) of Point Hope, Alaska, represent two environmentally similar, although culturally and temporally different, populations. Based on associated archaeological finds, the Ipiutak do not represent a whaling culture. Instead, they focused on hunting smaller sea mammals and caribou. Conversely, the Tigara represent a typical Inuit whaling culture. Whaling cultures depend on a distinct division …

Biologically Inspired Learning System, Patrick Mcdowell

LSU Doctoral Dissertations

Learning Systems used on robots require either a-priori knowledge in the form of models, rules of thumb or databases or require that robot to physically execute multitudes of trial solutions. The first requirement limits the robot’s ability to operate in unstructured changing environments, and the second limits the robot’s service life and resources. In this research a generalized approach to learning was developed through a series of algorithms that can be used for construction of behaviors that are able to cope with unstructured environments through adaptation of both internal parameters and system structure as a result of a goal based …

Samuel Beckett And Bilingualism: How The Return To English Influences The Later Writing Style And Gender Roles Of All That Fall And Happy Days, Julien F. Carriere

LSU Doctoral Dissertations

This dissertation addresses Samuel Beckett's bilingualism in an effort to understand how the author's use of language affected his writing style and depiction of gender. Beckett began writing in English, switched to French for the composition of new works for ten years, and then returned unexpectedly to English. His first English works are characterized by stylistic virtuosity, erudition, and misogyny. With Beckett's adoption of French his style became simple, spare, and cerebral. Plot structure based on a journey in early works was abandoned in favor of static situations and dialogue. Women were either ignored or viewed negatively. In 1956, Beckett …

Charity, Publicity, And The Donation Registry, Brian Broughman, Robert Cooter

Articles by Maurer Faculty

Many Americans donate little or nothing to charity, but according to Robert Cooter and Brian Broughman, our social environment is the cause, not human nature. They propose a small policy change to increase transparency and elicit generosity inspired by experimental evidence about the nature of giving.

Conspiracy Culture In America After World War Ii, Valerie Rose Holliday

LSU Doctoral Dissertations

Feminism has all too often been reified as a theoretical category. Specifically, Marxist critical categories fail to account for the integral importance of gender in any sociopolitical critique. This dissertation attempts to dereify gender and demonstrate a theoretical model that seamlessly integrates psychoanalysis, Marxism, and feminism. Conspiracy culture in America since World War II is an ideal aperture through which we may envision such a theoretical approach, and indeed see the critical need for such an approach. This dissertation looks at several post-war American conspiracy narratives, including Oliver Stone’s JFK and Nixon, Don DeLillo’s Libra, Sidney Lumet’s Fail Safe, John …

Prophylactic Defibrillator Implantation—Toward An Evidence-Based Approach, Alan H. Kadish

The author discusses research on using implantable cardioverter-defibrillators for the primary prevention of sudden death.

Cultural Performance Of Roadside Shrines: A Poststructural Postmodern Ethnography, Rebecca Marie Kennerly

LSU Doctoral Dissertations

Marking the site of death on the road with a shrine, an increasingly popular cultural practice in the United States, is a deeply personal, private affair, however, because shrines are placed in the public right-of-way, they attract attention and invite participation, comment, and criticism. These sites, the materials that mark them, how people come to build them, the messages that those who build them hope to convey, and the accumulative force these sites bring to bear in various contexts offer unique insights into our complex, fragmented, and often confounding relationships with death, living memory, and selective forgetting. This project takes …

Multicultural Lawyering: Teaching Psychology To Develop Cultural Self-Awareness, Carwina Weng

Articles by Maurer Faculty

Much of the current literature in multicultural lawyering focuses on learning substantive information about clients who are culturally different from the lawyer, such as how the client's culture perceives eye contact or reacts to science-based world views. This article notes that such a focus sidesteps the human reality that every person reacts to people who are different from him- or herself unconsciously in ways that may be culturally insensitive and discriminatory and that this human reaction occurs despite awareness of the general values, attitudes, and beliefs of the client's culture. It therefore suggests that multicultural lawyering training should begin with …

Foreign News Coverage In Selected U.S. Newspapers 1927-1997: A Content Analysis, Cleo Joffrion Allen

LSU Doctoral Dissertations

This content analysis was designed to examine, in a single longitudinal study, trends in the quantity and kinds of world news coverage in selected U.S. newspapers during times of relative peace. Using complementary proportion and absolute-item frequencies, two constructed weeks in 1927, 1947, 1977, and 1997 in three newspapers, 168 issues in all, were analyzed. The findings indicate that the percentage of foreign news coverage compared to non-foreign coverage in the three newspapers actually increased between 1927 and 1997. The amount of foreign coverage spiked in 1947 and then started to decline. But even with the decline, coverage by proportion …

Relative Permeability And Wettability Implications Of Dilute Surfactants At Reservoir Conditions, Ayodeji Adebola Abe

LSU Master's Theses

The improvement or increase of oil recoverable from discovered reservoirs has always been a very important issue as this helps to meet ever growing energy demand. Several methods have been put forward as means of achieving this objective. Chemical flooding, using surfactants has been considered in enhanced oil recovery processes. Surfactants are used primarily to lower oil-water interfacial tension (IFT) and thus improve production. However, surfactants possess the ability to alter rock wettability and hence increase oil production. Previous investigations were performed at ambient conditions using stocktank oil. Extrapolation of the findings from the ambient conditions testing to reservoir conditions …

"Let Me Play A While": Storytelling Characters And Voices In The Works Of Mark Twain, William Faulkner, And Lee Smith, Kenneth Mark Broyles

LSU Doctoral Dissertations

This dissertation focuses on the difference between narrators and characters in fiction who tell stories. It also argues that traditional orality persists in American culture and is a significant influence in the fiction of Mark Twain, William Faulkner and Lee Smith. In their work, they try to overcome what some perceive as a structural discrimination inherent in the novel and imbue their characters' speaking voices with authority that is determined by something other than their position in the structural hierarchy. All three authors attempt to give their characters speaking voices which are not necessarily inferior to the narrative or authorial …

Chemistry Faculty Publications and Presentations

The release of the 1000^th complete microbial genome will occur in the next two to three years. In anticipation of this milestone, the Fellowship for Interpretation of Genomes (FIG) launched the Project to Annotate 1000 Genomes. The project is built around the principle that the key to improved accuracy in high through put annotation technology is to have experts annotate single subsystems over the complete collection of genomes, rather than having an annotation expert attempt to annotate all of the genes in a single genome. Using the subsystems approach, all of the genes implementing the subsystem are analyzed by …

Analysis Of The Talus And Calcaneus Bones From The Poole-Rose Ossuary: A Late Woodland Burial Site In Ontario, Canada, Adrienne Elizabeth Penney

LSU Master's Theses

This study reports on the demography and osteological profile of the Poole-Rose Ossuary. Excavated in 1990 under the direction of Heather McKillop and at the request of the Alderville First Nation, the Poole-Rose Ossuary is a Late Woodland burial site in southern Ontario, Canada. Lack of European artifacts in the burial suggests that this site predates European contact. The Poole-Rose Ossuary is radiocarbon dated to A.D. 1550 ± 50 years. The skeletal remains were commingled. This ossuary likely represents the mass re-burial known as the “Feast of the Dead” or the “Kettle.” For the most part, closely related individuals were …

A Project Improvement System For Effective Management Of Construction Projects, Shahriyar Mojahed

LSU Doctoral Dissertations

The concept of construction productivity began in the early 20th century with a series of time and motion studies to improve bricklaying operations. A substantial number of subsequent studies focused on repetitive tasks and automation of the manufacturing operations and subsequently benefited manufacturing more than the construction industry. There has been a lack of studies for productivity improvement in the construction industry. Building upon the available body of knowledge as it related to productivity of manufacturing and construction industries, this study focused on developing a project improvement system for effective management of construction projects. Development of the system included a …

This is a foreword to articles submitted as part of the Association of American Law School’s Symposium during at the January 2004 AALS’s Annual Meeting in Atlanta, Georgia entitled "Competing or Complementary Rule Systems? Adjudication, Arbitration and the Procedural World of the Future." The session brought together panelists whose expertises ranged across the academy. The legal academics were joined by the federal district judge now chairing the committee charged by the Judicial Conference of the United States to draft federal civil procedural rules. The stimulating session reflected on the relationship between litigation and non-litigation approaches to dispute resolution. Participants explored …

Road Rage And R.S. 2477: Judicial And Administrative Responsibility For Resolving Road Claims On Public Land, Bret C. Birdsong

Scholarly Works

The past decade has seen the D-4 Caterpillar bulldozer become a significant tool for those seeking to challenge federal land management agencies' authority to protect resources federal lands by reducing access. The power of the bulldozer is both symbolic and pragmatic. It cuts an iconographic image of local officials standing up against federal control over vast areas of land in the rural west. But it also, in many cases, provokes litigation, allowing claims to property rights to receive judicial attention that might otherwise evade them.

Underlying each of these protagonist's legal positions, if not their motivations, is a right-of-way grant …

Evidence Of Neotectonic Activity In Southwest Louisiana, Jordan Oliver Heltz

LSU Master's Theses

A methodology that combines high-resolution topographic mapping, field observations, subsurface evaluation, and geodetic data analysis has successfully located several fault-related geomorphic steps in an area of southwestern Louisiana once thought to be relatively devoid of such features. Comparison of height differences of benchmarks straddling these suspected fault-related steps shows that vertical displacement rates on faults in the study area ranged from about 2 mm/yr to as much as 6 mm/yr during the 1960’s and 1970’s. However, leveling data obtained as recently as January 2005 reveals that the majority of these faults are currently moving at rates of less than 1 …
