A Predictive Model For Secondary Rna Structure Using Graph Theory And A Neural Network., Denise Renee Koessler

Electronic Theses and Dissertations

In this work we use a graph-theoretic representation of secondary RNA structure found in the database RAG: RNA-As-Graphs. We model the bonding of two RNA secondary structures to form a larger structure with a graph operation called merge. The resulting data from each tree merge operation is summarized and represented by a vector. We use these vectors as input values for a neural network and train the network to recognize a tree as RNA-like or not based on the merge data vector.

The network correctly assigned a high probability of RNA-likeness to trees identified as RNA-like in the RAG database, …

Error Correcting Codes And The Human Genome., Suzanne Mclean Lyle

Electronic Theses and Dissertations

In this work, we study error correcting codes and generalize the concepts with a view toward a novel application in the study of DNA sequences. The author investigates the possibility that an error correcting linear code could be included in the human genome through application and research. The author finds that while it is an accepted hypothesis that it is reasonable that some kind of error correcting code is used in DNA, no one has actually been able to identify one. The author uses the application to illustrate how the subject of coding theory can provide a teaching enrichment activity …

Generating Compact Wasp Nest Structures Via Minimal Complexity Algorithms., Fadel Ewusi Kofi Adoe

Electronic Theses and Dissertations

Many models have been developed to explain the process of self organization-the emergence of seemingly purposeful behaviors from groups of entities with limited individual intelligence. However, the underlying behavior that facilitates the emergence of this global pattern is not generally well understood. Our study focuses on different low complexity building algorithms and characterizes how nests are built using these algorithms. Three rules postulated to be functions of wasps' building behavior were developed. First is the random rule, in which there is no constraint per the choice of site to be initiated. The second is the 2-cell rule where only sites …

A Family-Based Association Study Of Conduct Disorder., Xueqiu Jian

Electronic Theses and Dissertations

Conduct disorder (CD) is a psychiatric syndrome in childhood and adolescence that is one of the most common childhood disorders with continuously increasing prevalence but uncertain pathogenesis. We performed a genome-wide, family-based association study of CD using P2BAT/FBAT software. The data is gathered from Collaborative Study on the Genetics of Alcoholism (COGA) and International Multi-Center ADHD Genetics Project (IMAGE).

Using COGA data, we identified 20 markers which showed suggestive associations (p<10^-3) with CD. Nine of them are located in known genes. Two genes, ADAM10 and CAMK2A, which had been reported associated with Alzheimer's disease (AD), bipolar disorder, …

Exploring Brand Personality Through Archetypes., Candice Roberts

Electronic Theses and Dissertations

Though brands are created and maintained using many different management strategies, market and academic research has offered evidence that brands presenting the strongest personalities are more likely to perform better and resonate longer with consumers. This paper examines the components of brand personality using connections between contemporary branding and 13 classic archetypes. The study also discusses the life cycle of the brand, including development of brand personality and achievement of iconic status in conjunction with archetypal marketing. The research of Faber and Mayer (2009) is the basis for an analysis measuring participant attitudes toward popular brands by matching them with …

A Safeguards Design Strategy For Domestic Nuclear Materials Processing Facilities., Jonathan Long

Electronic Theses and Dissertations

The outdated and oversized nuclear manufacturing complex within the United States requires its transformation into a smaller, safe, and secure enterprise. Health and safety risks, environmental concerns, and the end of the Cold War have all contributed to this necessity. The events of September 11, 2001, emphasized the protection requirements for nuclear materials within the U.S. as well as abroad.

Current Nuclear Safeguards regulations contain minimal prescriptive requirements relating to the design of new production facilities. Project management and engineering design guides require that design documents contain specific and measureable statements relating to systems requirements. The systems engineering process evaluates …

Using Ant Colonization Optimization To Control Difficulty In Video Game Ai., Joshua Courtney

Undergraduate Honors Theses

Ant colony optimization (ACO) is an algorithm which simulates ant foraging behavior. When ants search for food they leave pheromone trails to tell other ants which paths to take to find food. ACO has been adapted to many different problems in computer science: mainly variations on shortest path algorithms for graphs and networks.

ACO can be adapted to work as a form of communication between separate agents in a video game AI. By controlling the effectiveness of this communication, the difficulty of the game should be able to be controlled. Experimentation has shown that ACO works effectively as a form …

Black And White On Black: Whiteness And Masculinity In The Works Of Three Australian Writers - Thomas Keneally, Colin Thiele, And Patrick White., Matthew Israel Byrge

Electronic Theses and Dissertations

White depictions of Aborigines in literature have generally been culturally biased. In this study I explore four depictions of Indigenous Australians by white Australian writers. Thomas Keneally's The Chant of Jimmie Blacksmith (1972) depicts a half-caste Aborigine's attempt to enter white society in a racially-antipathetic world that precipitates his ruin. Children's author Colin Thiele develops friendships between white and Aboriginal children in frightening and dangerous landscapes in both Storm Boy (1963) and Fire in the Stone (1973). Nobel laureate Patrick White sets A Fringe of Leaves (1976) in a world in which Ellen Roxburgh's quest for freedom comes only through …

Partner Violence During Pregnancy: Prevalence, Effects, Screening, And Management, Beth A. Bailey

ETSU Faculty Works

The purpose of this review is to provide an overview of the current state of knowledge regarding the experience of intimate partner violence (IPV) during pregnancy. Pregnancy IPV is a significant problem worldwide, with rates varying significantly by country and maternal risk factors. Pregnancy IPV is associated with adverse newborn outcomes, including low birth weight and preterm birth. Many mechanisms for how IPV may impact birth outcomes have been proposed and include direct health, mental health, and behavioral effects, which all may interact. Screening for IPV during pregnancy is essential, yet due to time constraints and few clear recommendations for …

Mitochondrial Function As A Determinant Of Life Span, Ian R. Lanza, K. S. Nair

ETSU Faculty Works

Average human life expectancy has progressively increased over many decades largely due to improvements in nutrition, vaccination, antimicrobial agents, and effective treatment/prevention of cardiovascular disease, cancer, etc. Maximal life span, in contrast, has changed very little. Caloric restriction (CR) increases maximal life span in many species, in concert with improvements in mitochondrial function. These effects have yet to be demonstrated in humans, and the duration and level of CR required to extend life span in animals is not realistic in humans. Physical activity (voluntary exercise) continues to hold much promise for increasing healthy life expectancy in humans, but remains to …

Developing the capacity of full-time and adjunct faculty to be co-facilitators of program change resulted in the transformation of a disjointed program into a jointed, well-grounded program based on the co-equal foundation of scholarship and practice.

A Comparative Content Analysis Of Televised Political Advertising In The United States And Canada In 2004 And 2008., Jessica A. Mahone

Electronic Theses and Dissertations

Analyzing 195 televised political ads from the United States and Canada in 2004 and 2008, this research studies the use of issue and image ads and the attack, acclaim, and contrast function of ads in presidential and federal elections. Results indicate that there is no statistical difference in the use of issue or image ads and no statistical difference in the function of ads in both nations in 2004 and 2008. Issue ads are found to be more commonly used in Canada than in the United States, but there is no statistical difference in the use of acclaim ads between …

A Use Of Theory Of Constraints Thinking Processes For Improvements In The Merged Beams Experiment At Oak Ridge National Laboratory., Bryan Richard Gross

Electronic Theses and Dissertations

Thinking exercises used in the Theory of Constraints (TOC) were used to find and remove constraints at the Merged Beams Experiment at Oak Ridge National Laboratory. The goal of this project was to significantly reduce the amount of time used to take a certain type of measurement during an experimental cycle. After the TOC exercises were used, a basic plan for change was discovered. Preliminary data were taken to establish a baseline of performance from which changes were made. Post-Modification was analyzed showing the project was a success.

The overlying reasoning for this exercise was to prove successfully that continuous …
