Perspective By Incongruity In Visual Advertising: Applying Kenneth Burke's Theory To The Adbusters Anti-Consumerism Campaign, Elizabeth B. Gorman Jan 2006

Perspective By Incongruity In Visual Advertising: Applying Kenneth Burke's Theory To The Adbusters Anti-Consumerism Campaign, Elizabeth B. Gorman

Theses

Kenneth Burke developed the theory of "perspective by incongruity" in which he claimed that oddly juxtaposed symbols influence audiences to have new perspectives by challenging their habits of thinking. This study applies Kenneth Burke's rhetorical theory of perspective by incongruity to the Adbusters anti-consumerism campaign. Twenty "spoof ad" postcards created by the Adbusters Media Foundation were analyzed to see how they utilize the technique of incongruous juxtaposition. The analysis concluded that the cards either juxtaposed two incongruous images, two incongruous phrases or words, or a combination of incongruous words and images in order to create new insights about consumer advertising …

Controlling Performance Of Crumb Rubber-Modified Binders Through Addition Of Polymer Modifiers, Magdy Abdelrahman Jan 2006

Controlling Performance Of Crumb Rubber-Modified Binders Through Addition Of Polymer Modifiers, Magdy Abdelrahman

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The use of tire rubber as a modifier to enhance the properties of asphalt mixes through the wet process has proved to be a successful procedure, but full control of the properties of crumb rubber-modified binders has been a challenge. The literature indicates a wide variation on adding rubber to asphalt and that the degree of success of rubber modification in AC mixes depends on several factors, the majority of which relate to the method of mixing, storing, and transporting and to construction technologies. Understanding the nature of the interaction process between asphalt cement and crumb rubber-modifier (CRM) helps explain …

Improving Prediction Accuracy In Mechanistic-Empirical Pavement Design Guide, Scott Schram, Magdy Abdelrahman Jan 2006

Improving Prediction Accuracy In Mechanistic-Empirical Pavement Design Guide, Scott Schram, Magdy Abdelrahman

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Model calibration plays a fundamental role in the implementation of the mechanistic-empirical pavement design guide. The data used in the default calibration effort, which were afforded by the Long Term Pavement Performance (LTPP) database, have a network-level inference space. As implementation proceeds, state highway agencies may be inclined to calibrate at a local network level. However, with a focus on the calibration data set to local project-level conditions, model prediction error can be reduced further. Under this study, Nebraska Department of Roads Pavement Management System data were used to calibrate two design guide smoothness models at the local project level. …

Disinfection Of Swine Wastewater Using Chlorine, Ultraviolet Light And Ozone, John J. Macauley, Zhimin Qiang, Rao Y. Surampalli, Melanie R. Mormile, Craig D. Adams

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Veterinary antibiotics are widely used at concentrated animal feeding operations (CAFOs) to prevent disease and promote growth of livestock. However, the majority of antibiotics are excreted from animals in urine, feces, and manure. Consequently, the lagoons used to store these wastes can act as reservoirs of antibiotics and antibiotic-resistant bacteria. There is currently no regulation or control of these systems to prevent the spread of these bacteria and their genes for antibiotic resistance into other environments. This study was conducted to determine the disinfection potential of chlorine, ultraviolet light and ozone against swine lagoon bacteria. Results indicate that a chlorine …

Circuit Models For Power Bus Structures On Printed Circuit Boards Using A Hybrid Fem-Spice Method, Todd H. Hubing, Chunlei Guo Jan 2006

Circuit Models For Power Bus Structures On Printed Circuit Boards Using A Hybrid Fem-Spice Method, Todd H. Hubing, Chunlei Guo

Electrical and Computer Engineering Faculty Research & Creative Works

Power bus structures consisting of two parallel conducting planes are widely used on high-speed printed circuit boards. In this paper, a full-wave finite-element method (FEM) method is used to analyze power bus structures, and the resulting matrix equations are converted to equivalent circuits that can be analyzed using SPICE programs. Using this method of combining FEM and SPICE, power bus structures of arbitrary shape can be modeled efficiently both in the time-domain and frequency-domain, along with the circuit components connected to the bus. Dielectric loss and losses due to the finite resistance of the power planes can also be modeled. …

Distributed Power Control For Cellular Networks In The Presence Of Channel Uncertainties, Maciej Jan Zawodniok, Q. Shang, Jagannathan Sarangapani Jan 2006

Distributed Power Control For Cellular Networks In The Presence Of Channel Uncertainties, Maciej Jan Zawodniok, Q. Shang, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a novel distributed power control (DPC) scheme for cellular network in the presence of radio channel uncertainties such as path loss, shadowing, and Rayleigh fading is presented. Since these uncertainties can attenuate the received signal strength and can cause variations in the received Signal-to-Interference ratio (SIR), a new DPC scheme, which can estimate the slowly varying channel uncertainty, is proposed so that a target SIR at the receiver can be maintained. Further, the standard assumption of a constant interference during a link's power update used in other works in the literature is relaxed. A CDMA-based cellular network …

Hdp Based Optimal Control Of A Grid Independent Pv System, Richard L. Welch, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents an adaptive optimal control scheme for a grid independent photovoltaic (PV) system consisting of a PV collector array, a storage battery, and loads (critical and non-critical loads). The optimal control algorithm is based on the model-free heuristic dynamic programming (HDP), an adaptive critic design (ACD) technique which optimizes the control performance based on a utility function. The HDP critic network is used in a PV system simulation study to train a neurocontroller to provide optimal control for varying PV system output energy and load demands. The emphasis of the optimal controller is primarily to supply the critical …

Recurrent Neural Network Based Predictions Of Elephant Migration In A South African Game Reserve, Parviz Palangpour, Ganesh K. Venayagamoorthy, Kevin Duffy Jan 2006

Recurrent Neural Network Based Predictions Of Elephant Migration In A South African Game Reserve, Parviz Palangpour, Ganesh K. Venayagamoorthy, Kevin Duffy

Electrical and Computer Engineering Faculty Research & Creative Works

A large portion of South Africa''s elephant population can be found on small wildlife reserves. When confined to enclosed reserves the elephant densities are much higher than observed in the wild. The large nutritional demands and destructive foraging behavior of elephants threaten rare species of vegetation. If conservation management is to protect threatened species of vegetation, knowing how long elephants will stay in one area of the reserve as well as which area they will move to next is essential. The goal of this study is to train a recurrent neural network (RNN) to continuously predict an elephant herd''s next …

An Evolutionary Computation Approach To Optimization Of Isoelectric Point Prediction In Proteins, Chris Parkin Jan 2006

An Evolutionary Computation Approach To Optimization Of Isoelectric Point Prediction In Proteins, Chris Parkin

Theses

Computational biology has attacked the problem of isoelectric point prediction with little success, achieving a rough accuracy level of only 30%. In 2005, Matthew Conte performed a study focused on the relationship between sequence characteristics and isoelectric point prediction accuracy. Results indicated that charges between adjacent amino acids could have a significant impact on the overall predicted pi for the protein. In this study we introduce an evolutionary computation approach aimed at accounting for these problem dipeptides. For each possible dipeptide involving charged amino acids (7 chargeable groups -> 49 possibilities), the algorithm predicts a pKa value that, when included …

The Thiol Redox System In Oxldl-Induced Macrophage Injury, Yanmei Wang Jan 2006

The Thiol Redox System In Oxldl-Induced Macrophage Injury, Yanmei Wang

University of Kentucky Master's Theses

Macrophage death is likely to contribute to the transformation of fatty streaks into advanced atherosclerotic lesions. Previous work in the laboratory showed that OxLDL promotes cell death in human macrophages by a mechanism involving intracellular peroxide formation. Here we show that glutathione depletion induced by OxLDL occurs independent of peroxyl radical formation. Our data suggest that the depletion of glutathione is the fundamental defect that renders macrophages susceptible to OxLDL-induced cell injury, but alone is not sufficient to kill macrophages. We indicate that increased protein-Sglutathionylation is involved in OxLDL-induced macrophage death. A potentiation of OxLDL toxicity was observed in macrophages …

Wear Tolerance Of Seeded And Vegetatively Propagated Bermuda Grasses Under Simulated Athletic Traffic, Theresa A. Bayrer Jan 2006

Wear Tolerance Of Seeded And Vegetatively Propagated Bermuda Grasses Under Simulated Athletic Traffic, Theresa A. Bayrer

University of Kentucky Master's Theses

The use of seed-propagated bermudagrasses [Cynodon dactylon (L.) Pers.], particularly for athletic fields, is rapidly increasing. Recently developed seeded cultivars have been bred for improved turfgrass quality (finer texture, darker green color, etc.) and for increased cold tolerance, but their ability to tolerate wear has not been investigated. This study was conducted to determine if three seeded cultivars could tolerate simulated athletic wear as well as one vegetative cultivar commonly used in Kentucky. The seeded cultivars, Riviera, Princess 77 and Yukon were planted at 24.4 and 48.8 kg PLS ha-1 and the vegetative cultivar Quickstand was sprigged at 1250 and …

The Relationship Between Emotional Recognition And Personality Traits, Lyndon A. Mitchell Jan 2006

The Relationship Between Emotional Recognition And Personality Traits, Lyndon A. Mitchell

Theses

This study investigated the relationship between personality traits and the ability to recognize emotions from facial expressions. A sample of undergraduate and graduate students (n = 52) were administered the 16 Personality Factor Questionnaire 5th Edition (16PF-5) (Cattell, 1993) and an abbreviated version of Ekman's Pictures of Facial Affect (Ekman & Friesen, 1976). Pearson product-moment correlations revealed that the personality trait, Apprehension, was associated with the accurate recognition of most of the emotions. Further, regression analyses revealed that the recognition of fear was best predicted by the 16PF factors Dominance, Self Reliance and Apprehension. Personality differences were also identified between …

Putting The Community Back Into Community Networks: A Content Analysis, Michael A. Horning Jan 2006

Putting The Community Back Into Community Networks: A Content Analysis, Michael A. Horning

Theses

This study examines the role that community networks can take in fulfilling McQuail's call for a more democratic participant form of media. Community networks, which are grassroots organizations designed to promote local community initiatives, increased their presence on the Internet in the 1990s. However, in recent years their number has declined. Research suggests that community networks fail because they lack a unified identity, have not determined their specific purpose on the Web, and do not provide relevant information to network members. Findings suggest that community networks wishing to achieve sustainability should concentrate their efforts on developing social capital and fostering …

Graph Reconstruction Numbers, Brian Mcmullen Jan 2006

Graph Reconstruction Numbers, Brian Mcmullen

Theses

The Reconstruction Conjecture is one of the most important open problems in graph theory today. Proposed in 1942, the conjecture posits that every simple, finite, undirected graph with more than three vertices can be uniquely reconstructed up to isomorphism given the multiset of subgraphs produced by deleting each vertex of the original graph. Related to the Reconstruction Conjecture, reconstruction numbers concern the minimum number of vertex deleted subgraphs required to uniquely identify a graph up to isomorphism. During the summer of 2004, Jennifer Baldwin completed an MS project regarding reconstruction numbers. In it, she calculated reconstruction numbers for all graphs …

Modeling Radiated Emissions From Cables Attached To Printed Circuit Boards Driven By Power Bus Noise, K. Morishita, N. Kobayashi, T. Harada, H. Ke, Todd H. Hubing Jan 2006

Modeling Radiated Emissions From Cables Attached To Printed Circuit Boards Driven By Power Bus Noise, K. Morishita, N. Kobayashi, T. Harada, H. Ke, Todd H. Hubing

Electrical and Computer Engineering Faculty Research & Creative Works

This paper describes a two-step technique for modeling the radiated electromagnetic emissions from a printed circuit board with attached cables when the source of the emissions is noise between the board's power and ground planes. the first step calculates the electric fields at the edges of the power-ground plane pair. the second step replaces the power plane with equivalent sources embedded within the ground plane structure. Examples are provided that demonstrate the accuracy of this approach. © 2006 IEEE.

Graph Reconstruction Numbers, Jennifer Baldwin Jan 2006

Graph Reconstruction Numbers, Jennifer Baldwin

Theses

One of the most important open questions in graph theory is the graph reconstruction conjecture, first proposed by P. J. Kelly and S. M. Ulam in 1941. The conjecture states that every graph with at least 3 vertices is reconstructible if there exists some multi-subset of vertex-deleted subgraphs that reconstructs G uniquely up to isomorphism. This project computes the existential and universal reconstruction numbers for all graphs of order at most nine. The existential reconstruction number is the number of vertex-deleted subgraphs, or cards, required to reconstruct G uniquely up to isomorphism. The universal reconstruction number is the minimum num- …

Tuple Board: A New Distributed Computing Paradigm For Mobile Ad Hoc Networks, Chaithanya Bondada Jan 2006

Tuple Board: A New Distributed Computing Paradigm For Mobile Ad Hoc Networks, Chaithanya Bondada

Theses

In this project, we introduce a new distributed computing paradigm called "tuple board" which is based on the tuple space abstraction originated by Gelernter and the blackboard architecture popular in distributed artificial intelligence. Most prominent implementations of tuple space systems including JavaSpaces and T-Spaces follow a centralized architecture where the space itself resides on a server, akin to a database server. Recently, researchers have attempted to develop decentralized architectures for tuple space systems. Some work includes LIME and PeerSpaces. In our opinion, the traditional implementation of tuple spaces is not well suited for ad hoc networks where devices frequently lose …

Real-Time Scheduling Algorithms, Task Visualization, Kevin Churnetski Jan 2006

Real-Time Scheduling Algorithms, Task Visualization, Kevin Churnetski

Theses

Real-time systems are computer systems that require responses to events within specified time limits or constraints. Many real-time systems are digital control systems comprised entirely of binary logic or a microprocessor dedicated to one software application that is its own operating system. In recent years, the reliability of general-purpose real-time operating systems (RTOS) consisting of a scheduler and system resource management have improved. In this project, I write a real-time simulator, a workload generator, analysis tools, several test cases, and run and interpret results. My experiments focus on providing evidence to support the claim that for the Rate Monotonic scheduling …

The Study Of Ramsey Numbers R(C_K, C_K, C_K), Yan Li Jan 2006

The Study Of Ramsey Numbers R(C_K, C_K, C_K), Yan Li

Theses

The Ramsey number r(C_k, C_k, C_k), denoted as r_3(C_k), is the smallest positive integer n such that any edge coloring with three colors of the complete graph on n vertices must contain at least one monochromatic cycle C_k. In this project, most literature on the Ramsey numbers r_3(C_k) are overviewed. Algorithms to check if a graph G contains any specific path or cycle and to construct extremal graphs for cycle C_k are developed. All good 3-colorings of complete graph K_10 are constructed to verify the value of Ramsey number r_3(C_4). Ramsey number value of r_3(C_3) is verified by direct point …
