Thermal Management Of The Lsu Micro Gas Chromatograph, Praveen K. Pasupuleti Jan 2005

Thermal Management Of The Lsu Micro Gas Chromatograph, Praveen K. Pasupuleti

LSU Master's Theses

Gas chromatography is a technique widely used for the separation and analysis of gas samples. Gas chromatographs are used for environmental maintenance, monitoring sophisticated biological analyses, and to separate components from a mixture of gases for mass spectrometer analysis. There has been a tremendous interest in miniaturization of gas chromatograph systems because of the potential for portability, faster response time, lower dead volume, lower power consumption, and lower cost of operation. Conventional gas chromatography keeps the column at a constant temperature during separation, which is called isothermal analysis. Temperature programming is a mode of gas chromatography in which the column …

Energy-Rate Based Mac Protocol For Wireless Sensor Networks And Key Pre-Distribution Schemes, Ramaraju Kalidindi Jan 2005

Energy-Rate Based Mac Protocol For Wireless Sensor Networks And Key Pre-Distribution Schemes, Ramaraju Kalidindi

LSU Master's Theses

Sensor networks are typically unattended because of their deployment in hazardous, hostile or remote environments. This makes the problem of conserving energy at individual sensor nodes challenging. S-MAC and PAMAS are two MAC protocols which periodically put nodes (selected at random) to sleep in order to achieve energy savings. Unlike these protocols, we propose an approach in which node duty cycles (i.e sleep and wake schedules) are based on their criticality. A distributed algorithm is used to find sets of winners and losers, who are then assigned appropriate slots in our TDMA based MAC protocol. We introduce the concept of …

Felt, Yvonne Pierce James Jan 2005

Felt, Yvonne Pierce James

LSU Master's Theses

My work is largely autobiographical and the way I express myself is the product of memories and life experiences. I grew up as one of a family of ten children and learned early the values of sharing and helping others. We were also taught not to waste anything. We learned to recycle as part of our daily life. As you will see in my work almost all of the materials I use are found objects or recycled materials. In growing up as part of a large, rural, southern family, there was also a tradition of ‘women’s work’. Nearly all of …

Black Catholicism: Religion And Slavery In Antebellum Louisiana, Lori Renee Pastor Jan 2005

Black Catholicism: Religion And Slavery In Antebellum Louisiana, Lori Renee Pastor

LSU Master's Theses

The practice of Catholicism extended across racial boundaries in colonial Louisiana, and interracial worship continued to characterize the religious experience of Catholics throughout the antebellum period. French and Spanish missionaries baptized natives, settlers, and slaves, and the Catholic Church required Catholic planters to baptize and catechize their slaves. Most slaveholders outside New Orleans, however, were lax in the religious education of slaves. Work holidays did not always correspond to religious holy days, and the number of slave baptisms and confirmations on Catholic plantations often depended on the willingness of the local priest, or the slaves themselves, to attend the parish …

Effects Of Adding Sediment To A Fresh Water Thin Mat Floating Marsh, Kate Carpenter Jan 2005

Effects Of Adding Sediment To A Fresh Water Thin Mat Floating Marsh, Kate Carpenter

LSU Master's Theses

Floating marshes are wetlands of emergent vascular vegetation which have a significant mat of live and dead roots, decomposing and dead organic material, and mineral sediments. This mat moves vertically as ambient water levels rise and fall. These marshes have unique hydrology in that overland sheet flow is reduced or eliminated leaving no inorganic sediment input, but there is extensive belowground water exchange. The effect of significant sediment introduction into wetlands with floating marshes is unknown. The purpose of this study was to observe the marsh mat response to Mississippi River sediment addition and measure species composition change and growth …

Reinforcement Magnitude: An Evaluation Of Preference And Reinforcer Potency, Nicole M. Trosclair Jan 2005

Reinforcement Magnitude: An Evaluation Of Preference And Reinforcer Potency, Nicole M. Trosclair

LSU Master's Theses

Reinforcers that maintain problem behavior often are an integral part of treatment with differential reinforcement. Basic research suggests that various parameters of reinforcement (e.g., rate, quality, delay, and magnitude) may influence treatment outcomes. Germane to the current study, the voluminous basic literature on reinforcement magnitude indicates that this parameter may influence responding, especially in choice situations or when response requirements are systematically increased over time. Although consideration of reinforcer magnitude may be important for maximizing treatment effectiveness, relatively little is known about children’s preference for different magnitudes of reinforcement or the extent to which relative preference would be related to …

A Study Of Distributed Clustering Of Vector Time Series On The Grid By Task Farming, Arun B. Nayar Jan 2005

A Study Of Distributed Clustering Of Vector Time Series On The Grid By Task Farming, Arun B. Nayar

LSU Master's Theses

Traditional data mining methods were limited by availability of computing resources like network bandwidth, storage space and processing power. These algorithms were developed to work around this problem by looking at a small cross-section of the whole data available. However since a major chunk of the data is kept out, the predictions were generally inaccurate and missed out on significant features that was part of the data. Today with resources growing at almost the same pace as data, it is possible to rethink mining algorithms to work on distributed resources and essentially distributed data. Distributed data mining thus holds great …

Platform Recruited Reef Fish, Phase I: Do Platforms Provide Habitat That Increase The Survival Of Juvenile Reef Fishes?, Lauren Kay Nowling Jan 2005

Platform Recruited Reef Fish, Phase I: Do Platforms Provide Habitat That Increase The Survival Of Juvenile Reef Fishes?, Lauren Kay Nowling

LSU Master's Theses

There are currently over 4000 functioning oil and gas platforms in the northern Gulf of Mexico (Gulf). Platform operations, and their prior drilling operations, produce trace amounts of lead, barium, vanadium, and lanthanum residues that are leached into the surrounding waters and are deposited on the sea floor. These residues have isotopic ratios different from those typical of the Gulf seafloor and can be used as harmless ‘fingerprints’ if they become incorporated into hard-parts or tissues in fishes associated with oil and gas platforms. From 2002 to 2004, 115 red snapper were collected from oil and gas platforms and artificial …

Sinker Cypress: Treasures Of A Lost Landscape, Christopher Aubrey Hurst Jan 2005

Sinker Cypress: Treasures Of A Lost Landscape, Christopher Aubrey Hurst

LSU Master's Theses

Sinker cypress (Taxodium spp.) logs are timbers that were lost during transit from harvest locations in the swamps and mill sites during the industrial cypress harvest from 1880-1930. A small industry has developed, concentrated on the recovery of sinker logs. Most of the persons involved in the recovery of sinker cypress, mill the logs into lumber, and sell the timber directly to consumers or to distributors. A smaller number of pullers retain the logs for personal use. Recovery operations are a costly endeavor and require a significant investment on the part of the harvesters. Most pullers are owner/operators who do …

New Contention Resolution Techniques For Optical Burst Switching, Kishore Reddy Koduru Jan 2005

New Contention Resolution Techniques For Optical Burst Switching, Kishore Reddy Koduru

LSU Master's Theses

Optical burst switching (OBS) is a technology positioned between wavelength routing and optical packet switching that does not require optical buffering or packet-level parsing, and it is more efficient than circuit switching when the sustained traffic volume does not consume a full wavelength. However, several critical issues still need to be solved such as contention resolution without optical buffering which is a key determinant of packet-loss with a significant impact on network performance. Deflection routing is an approach for resolving contention by routing a contending packet to an output port other than the intended output port. In OBS networks, when …

Teaching The Progressive Era Through The Life And Accomplishments Of Jane Addams, Kacy J. Taylor Jan 2005

Teaching The Progressive Era Through The Life And Accomplishments Of Jane Addams, Kacy J. Taylor

LSU Master's Theses

Because of standardized testing in Louisiana, the high school American history curriculum has been reduced to a long list of facts. Students no longer learn the story of American history – the people and events that have defined America as we know it. Instead, it is presented to them in fragmented pieces. Teachers move so quickly from subject to subject that they fail to explain the origin and transformation of ideas. This paper proposes teaching a period of history through the life of an important historical figure, in this case, Jane Addams. Through the life of Jane Addams, students can …

Sensorsimulator: Simulation Framework For Sensor Networks, Cariappa D. Mallanda

LSU Master's Theses

Wireless sensor networks have the potential to become significant subsystems of engineering applications. Before relegating important and safety-critical tasks to such subsystems, it is necessary to understand the dynamic behavior of these subsystems in simulation environments. There is an urgent need to develop a simulation platform that is useful to explore both the networking issues and the distributed computing aspects of wireless sensor networks. Current approaches to simulating wireless sensor networks largely focus on the networking issues. These approaches use well-known network simulation tools that are often difficult to extend to explore distributed computing issues. Discrete-event simulation is a trusted …

Liquid Architectures: Marcos Novak's Territory Of Information, Camile A. Silva Jan 2005

Liquid Architectures: Marcos Novak's Territory Of Information, Camile A. Silva

LSU Master's Theses

The idea of interactivity between humans and their environment no longer represents the only way of exploring new experiences. Equally passé is the idea that information constitutes the means for this interaction. However, this paper presents that the contemporary idea for interaction has embraced new understandings of the content of experience and the structure of space. New electronic technologies and advanced digital media have separated realities from the realm of the body and transformed experiences into a ubiquitous event. The architectural discourse, that once has been largely a discourse of form and style, has finally overcome those limitations and has …

Temporal Trends In Tchula Period Pottery In Louisiana, Steven Ray Fullen Jan 2005

Temporal Trends In Tchula Period Pottery In Louisiana, Steven Ray Fullen

LSU Master's Theses

Tchula period pottery (Tchefuncte culture) in Louisiana is characterized by highly contorted and laminated pastes. These diagnostic traits have led investigators to suggest hypotheses concerning manufacturing techniques, but there has been relatively little focus on temporal trends associated with these characteristics. The first step in redressing this problem was to identify a site likely to contain archaeological assemblages that would span the Tchula period. Excavations began at the Sarah Peralta site (16EBR67) in the fall of 2001 and were concluded in the spring of 2002. Artifacts from this site were characterized according to standard identification procedures. A secondary site, the …

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 …
