Computer-Aided Diagnosis Tool For The Detection Of Cancerous Nodules In X-Ray Images, Pallavi Bomma Jan 2005

Computer-Aided Diagnosis Tool For The Detection Of Cancerous Nodules In X-Ray Images, Pallavi Bomma

LSU Master's Theses

This thesis involves development of a computer-aided diagnosis (CAD) tool for the detection of cancerous nodules in X-ray images. Both cancerous and non-cancerous regions appear with little distinction on an X-ray image. For accurate detection of cancerous nodules, we need to differentiate the cancerous nodules from the non-cancerous. We developed an artificial neural network to differentiate them. Artificial neural networks (ANN) find a large application in the area of medical imaging. They work in a manner rather similar to the brain and have good decision making criteria when trained appropriately. We trained the neural network by the backpropagation algorithm and …

The Yes Men And Activism In The Information Age, Lani Boyd Jan 2005

The Yes Men And Activism In The Information Age, Lani Boyd

LSU Master's Theses

Western history is filled with pranks and trickery intent on enlightening audiences by blending fiction with reality. The Yes Men, an Internet-based activist group, did just that, forging new ground and establishing themselves as political pranksters in a media-dominant global society. With an arsenal of parody, satire, interventions, and tactical obfuscation, the Yes Men attack those who they feel abuse their positions of power. They have impersonated public persons and infamous entities, including President George W. Bush, the World Trade Organization, and Dow Chemical. Their mimicry is so convincing that the audience cannot decipher between satire and the real thing. …

Urban Yellow Fever Diffusion Patterns And The Role Of Micro-Environmental Factors In Disease Dissemination: A Temporal-Spatial Analysis Of The Memphis Epidemic Of 1878, William Brennan Arden Jan 2005

Urban Yellow Fever Diffusion Patterns And The Role Of Micro-Environmental Factors In Disease Dissemination: A Temporal-Spatial Analysis Of The Memphis Epidemic Of 1878, William Brennan Arden

LSU Master's Theses

Most investigations that examine diffusion of disease through urban areas give relatively scant attention to the 'micro-environment.' Employing the many methods of macro-environmental analysis, most studies do not attempt to identify street-level or even residence-level temporal-spatial patterns of disease diffusion. As a result, the mechanisms that lead to diffusion on such small scales are left relatively undefined. There is no doubt that cumulatively these small-scale mechanisms contribute to the diffusion of disease over the urban environment. However, the level of contribution and the specific details of their dynamics remain unclear. This thesis investigated some of these unexplored areas by presenting …

Fashion Involvement Of Affluent Female Consumers, Robin Danielle Mcfatter Jan 2005

Fashion Involvement Of Affluent Female Consumers, Robin Danielle Mcfatter

LSU Master's Theses

Fashion involvement is a consumer’s perceived importance of fashion clothing (O’Cass, 2001). It is important to investigate fashion involvement to understand consumer purchase behavior and to develop improved marketing strategies. Although researchers agree that consumers consider apparel purchases to be important, there has been little research done regarding fashion involvement (O’Cass, 2000) of affluent female consumers. The purpose of this study was to measure the fashion involvement of selected affluent female consumers from eight metropolitan areas in the United States and to identify relationships between fashion involvement and other selected variables. After controlling for socioeconomic demographic characteristics, the following variables …

Full Circle, Elizabeth Cowhig Jan 2005

Full Circle, Elizabeth Cowhig

LSU Master's Theses

My paintings are a result of a mainly intuitive process that evolves out of the combination of shape, color, and texture and originates from personal ideologies involving health phobias and religious beliefs. The imagery in the paintings is of biological origin, cells that fill up with matter, dense spheres that recall cancerous build up, the compositions and colors are inspired by Italian Renaissance paintings. The tangible is inserted into the realm of the ethereal.

The Battle Of New Orleans, Gregory Morris Thomas Jan 2005

The Battle Of New Orleans, Gregory Morris Thomas

LSU Master's Theses

America was not prepared for the War of 1812. The army and navy were so small they could not oppose Britain directly. American strategy in the first year called for the seizure of Canada. Multiple expeditions were complete failures resulting in military defeats and political embarrassment for President Madison. During the second year of the war there were more defeats for American forces, but some victories. These successes came mainly against Indians allied with the British along the frontier. The third and final year of the war started ominously. With Napoleons first abdication the wars in Europe seemed over, allowing …

Mapping Weak Multidimensional Torus Communications On Optical Slab Waveguides, Karthik Sethuraman Jan 2005

Mapping Weak Multidimensional Torus Communications On Optical Slab Waveguides, Karthik Sethuraman

LSU Master's Theses

This thesis deals with the mapping of communication of a d-dimensional weak torus on an optical medium. Our results are derived in the setting of a sawtooth slab waveguide. The mapping aims to reduce the number and cost of optical components, by exploiting the fact that not all edges of a weak topology are used simultaneously. This approach allows for a better utilization of the huge bandwidth of an optical slab waveguide; currently the cost and size of optical components external to the optical communication medium are the primary bottleneck of an optical interconnect. We introduce the notion of adjacency …

In The Garden, Christopher B. Hutson Jan 2005

In The Garden, Christopher B. Hutson

LSU Master's Theses

This body of artwork is centered on the idea of a garden as a space in between the two systems of human and natural order. The ambiguities of this in-between space tie together ideas pertinent to both worlds, using the ancient “doctrine of signatures” as an intermediary. These ideas are explored in fourteen artworks, including large-scale and smaller drawings, lithographs, and etchings.

Defining Modernity: Mentality And Ideology Under The French Second Empire, Gavin Murray-Miller Jan 2005

Defining Modernity: Mentality And Ideology Under The French Second Empire, Gavin Murray-Miller

LSU Master's Theses

This study intends to examine the relationship between popular conceptions of modernity and Republican ideology during the Second Empire, 1852-1870. With the advent of the industrial revolution in France, scientific knowledge came to be equated with notions of progress and innovation, leading intellectual elites to design philosophical and social systems predicated upon the authority of scientific analysis and objectivity. Influenced by the intellectual currents under the Second Empire, a new generation of Republican political theorists incorporated notions of science into their ideological outlook, ultimately engendering a moderate brand of Republicanism which played a significant role in the founding of the …

Aquinas And The Knowledge Of God, Casey Edler Jan 2005

Aquinas And The Knowledge Of God, Casey Edler

LSU Master's Theses

This thesis concerns the introduction of mystical knowledge into a debate about God that relies on scientific evidence. The thesis focuses in particular on the relevance of Thomas Aquinas' view of mystical experience. After first presenting Aquinas' theory of rapture as an anticipation of the beatific vision and distinguishing it from other ways of knowing God, I argue that such a theory convincingly renders mystical knowledge inadmissible into a debate about God that relies on scientific evidence, owing to one's inability to either remember or communicate such an experience. As a result, introducing mystical knowledge into the debate causes the …

Relative Permeability And Wettability Implications Of Dilute Surfactants At Reservoir Conditions, Ayodeji Adebola Abe Jan 2005

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 …

Feminist Hard-Boiled Detective Fiction As Political Protest In The Tradition Of Women Proletarian Writers Of The 1930s, Laura Ellen Ng Jan 2005

Feminist Hard-Boiled Detective Fiction As Political Protest In The Tradition Of Women Proletarian Writers Of The 1930s, Laura Ellen Ng

LSU Doctoral Dissertations

Contemporary feminist hard-boiled detective fiction has been studied as an adaptation of the traditional masculine hard-boiled detective genre. Writers such as Sara Paretsky, Sue Grafton, and Marcia Muller create compelling feminist protagonists to fill the role of detective. The successes and failures of these feminist detectives have then been measured against the standards created in the classic genre by Raymond Chandler, Dashiell Hammett, and James M. Cain. The classic hard-boiled masculine genre came of age in the 1930s and 1940s at the same time as proletarian literature. The two genres share many characteristics including reliance upon first person narrative, the …

Greenwashing: Visual Communication And Political Influence In Environmental Policy, Eric Jeffrey Jenner Jan 2005

Greenwashing: Visual Communication And Political Influence In Environmental Policy, Eric Jeffrey Jenner

LSU Doctoral Dissertations

Some contemporary theories in political science maintain that public lobbying is merely an expression of latent and resolute public opinion that is communicated to policymakers. Other theories contend that the public is highly manipulable and that public lobbying by extension can be considered a form of strategic framing that takes place through the news and paid media. Both theoretical approaches specify a function for words or text but are silent on the influence of photographs or images. In this dissertation, I hypothesize that environmental public lobbying operates as strategic framing and that text and photographs have unique and discrete effects …

Re-Conceptualizing Southern Rhetoric: A Meta-Critical Perspective, Christina L. Moss Jan 2005

Re-Conceptualizing Southern Rhetoric: A Meta-Critical Perspective, Christina L. Moss

LSU Doctoral Dissertations

The study of southern rhetoric and public address remains important to the study of American rhetoric and public address. However, recent years indicate a decline in the amount and variety of scholarship in this area of study. This project provides a meta-critical analysis of the history of southern rhetorical scholarship, focusing mainly on southern public address. By tracing ideology from the Agrarians, Richard Weaver, Dallas Dickey, Waldo Braden, Stephen Smith, and Stuart Towns, clear attitudes and definitions of the South, southern identity and southern rhetoric evolved to create an area of study in much need of revision.

Long Term Pressure Behavior In Turbidite Reservoirs, Feng Wang Jan 2005

Long Term Pressure Behavior In Turbidite Reservoirs, Feng Wang

LSU Doctoral Dissertations

In this study, we investigated several possible mechanisms that would give rise to the anomalous pressure behavior (early concave-up on Horner plot or upward drift on the derivative curve of the log-log plot and asymmetry between the pressure drawdown and buildup behavior) sometimes encountered in the turbidite reservoirs in GOM primarily using numerical simulation and 2-level experimental designs. We ascertained the most influential parameters to the pressure behavior and identified that multilayer commingled system and the leaky compartment model are the most probable mechanisms to cause the anomalous behavior due to layer or zone property contrast to a certain degree. …
