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 …

Voluntary Exercise In The C57b1/6j Mouse: Phenotypic Effects Of Varying Dietary Fat Levels And Hippocampal Gene Expression Differences Between High-Level And Low-Level Exercisers, Leslie Debardeleben Mclaughlin Jan 2005

Voluntary Exercise In The C57b1/6j Mouse: Phenotypic Effects Of Varying Dietary Fat Levels And Hippocampal Gene Expression Differences Between High-Level And Low-Level Exercisers, Leslie Debardeleben Mclaughlin

LSU Doctoral Dissertations

The drive to exercise voluntarily likely results from complex interactions between genes in many organ systems and various psychological parameters, such as motivation and the perception of fatigue. Reproducible variations in exercise intensity and duration are well established in laboratory rodents, but the genes responsible remain largely unknown. Also, to date, studies addressing the adaptive changes to exercise that might prevent dietary-induced obesity have focused primarily on energy intake and nutrient oxidation/partitioning, as opposed to genetics. We hypothesize that increased voluntary physical activity may be a normal mechanism in certain rodent strains to deter dietary-induced obesity and that in an …

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.

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 …

Cognitive Memory Effects On Non-Linear Video-Based Learning, Katherine Renee Comeaux Jan 2005

Cognitive Memory Effects On Non-Linear Video-Based Learning, Katherine Renee Comeaux

LSU Master's Theses

During an informative learning process, information, material, facts and ideas are typically conveyed in a linear arrangement. Individuals are frequently distracted during this process with their attention being diverted to an interruption (Internet, phone call, etc). When presented with any new information, the mind evolves through problem solving and evaluation procedures. The way in which that information is processed and perceived depends on: (a) original presentation (b) examination of material and (c) an individualistic measurement of success. However, when faced with an interruption, the person is forced to deal with non-linear arrangement of information. This research investigates nonlinear presentation or …

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 …

Naturally-Derived Porphyrin And Chlorin Photosensitizers For Photodynamic Therapy, Jodie Angela Hargus Jan 2005

Naturally-Derived Porphyrin And Chlorin Photosensitizers For Photodynamic Therapy, Jodie Angela Hargus

LSU Master's Theses

In oncologic applications of photodynamic therapy (PDT), the discriminating localization of porphyrin-type compounds in solid tumors is exploited for the selective ablation of neoplastic tissue with minimal destruction and irritation to normal tissue. PDT is a locoregional, binary cancer therapy in which a photosensitizer—light-activated drug—absorbs light of an appropriate wavelength and excites to the singlet state. This photosensitizer in the excited singlet state can undergo an internal transition to the excited triplet state, a relatively long-lived and high-energy species that transfers its excess energy to molecular oxygen. Molecular oxygen subsequently excites from the stable triplet state to the highly reactive …

Blood Work, Mack Gingles Jan 2005

Blood Work, Mack Gingles

LSU Master's Theses

The visual portion of BLOOD WORK is a record of my reconciliations with its parts: description based on the photograph, memory, and my concerns for abstraction. I am interested in the nuances of gesture as they convey meaning and evoke memory response. Though non-specific, the space surrounding the figures is emptied to accentuate their psychology. By adumbrating one reality and effacing another I attempt to transform the mundane into what I perceive as the uncanny.
