A Stabilized Rbf Collocation Scheme For Neumann Type Boundary Value Problems, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Rahimian, Mohammad Shekarchi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The numerical solution of partial differential equations (PDEs) with Neumann boundary conditions (BCs) resulted from strong form collocation scheme are typically much poorer in accuracy compared to those with pure Dirichlet BCs. In this paper, we show numerically that the reason of the reduced accuracy is that Neumann BC requires the approximation of the spatial derivatives at Neumann boundaries which are significantly less accurate than approximation of main function. Therefore, we utilize boundary treatment schemes that based upon increasing the accuracy of spatial derivatives at boundaries. Increased accuracy of the spatial derivative approximation can be achieved by h-refmement reducing the …

Vegetation Identification Based On Satellite Imagery, Vamsi K.R. Mantena, Ramu Pedada, Srinivas Jakkula, Yuzhong Shen, Jiang Li, Hamid R. Arabnia (Ed.)

Electrical & Computer Engineering Faculty Publications

Automatic vegetation identification plays an important role in many applications including remote sensing and high performance flight simulations. This paper presents a method to automatically identify vegetation based upon satellite imagery. First, we utilize the ISODATA algorithm to cluster pixels in the images where the number of clusters is determined by the algorithm. We then apply morphological operations to the clustered images to smooth the boundaries between clusters and to fill holes inside clusters. After that, we compute six features for each cluster. These six features then go through a feature selection algorithm and three of them are determined to …

Electrical & Computer Engineering Faculty Publications

In this paper, a 105 GHz millimeter wave interferometer system is used to measure the electron density and temperature of an atmospheric pressure helium plasma driven by submicrosecond pulses. The peak electron density and electron-neutral collision frequency reach 8 X 10¹² cm^-3 and 2.1 X 10¹² s^-1, respectively. According to the electron-helium collision cross section and the measured electron-neutral collision frequency, the electron temperature of the plasma is estimated to reach a peak value of about 8.7 eV.

Reproducible Increased Mg Incorporation And Large Hole Concentration In Gan Using Metal Modulated Epitaxy, Shawn D. Burnham, Gon Namkoong, David C. Look, Bruce Clafin, W. Alan Doolittle

Electrical & Computer Engineering Faculty Publications

The metal modulated epitaxy (MME) growth technique is reported as a reliable approach to obtain reproducible large hole concentrations in Mg-doped GaN grown by plasma-assisted molecular-beam epitaxy on c-plane sapphire substrates. An extremely Ga-rich flux was used, and modulated with the Mg source according to the MME growth technique. The shutter modulation approach of the MME technique allows optimal Mg surface coverage to build between MME cycles and Mg to incorporate at efficient levels in GaN films. The maximum sustained concentration of Mg obtained in GaN films using the MME technique was above 7 × 10²⁰ cm^{-3 …}

The Influence Of Street Culture On Brand Identity In Graphic Design, Holly Parshall

Theses

Problem Statement: This thesis explores the influence of street culture on brand identity in graphic design. Aspects of street culture include skateboarding, hip-hop, rap, punk, and street art. Street art is traditionally thought of as illegal or rebellious mark-making of public property or property that does not belong to the person making marks on it. Street art can also be defined as a means of crafting personal expression through the enhancement or augmentation of a natural or man-made environment. In this study, brand identity is defined as "the controllable and fundamental elements of a company, product, or service brand, such …

Automated Grazing Management, Gregory J. Von Pless

Theses

Management-intensive grazing is a grazing management strategy that relies on careful monitoring of animals at pasture and frequent relocation of animals between various regions of the pasture, or paddocks, in order to maximize the nutrients and sustenance the animals obtain through grazing. When applied successfully, this approach to grazing management yields higher animal production, while cutting feed costs; however, a great deal of overhead is introduced in monitoring and moving the animals throughout the pasture, making this approach very difficult to implement at a large scale. Recent successes in the field of dynamic virtual fencing have demonstrated the feasibility of …

A Framework For Integrating Dna Sequenced Data, Prabin Dutta

Theses

The Human Genome Project generated vast amounts of DNA sequenced data scattered in disparate data sources in a variety of formats. Integrating biological data and extracting information held in DNA sequences are major ongoing tasks for biologists and software professionals. This thesis explored issues of finding, extracting, merging and synthesizing information from multiple disparate data sources containing DNA sequenced data, which is composed of 3 billion chemical building blocks of bases. We proposed a biological data integration framework based on typical usage patterns to simplify these issues for biologists. The framework uses a relational database management system at the backend, …

The Manufactured Experience, Debra Ruzinsky

Theses

Repeatedly what I see around me are places and messages that generate manufactured experiences, manipulated by someone with an agenda to promote. My thesis work, entitled "Sweet Reassurance," is a personal approach to re-invention; a conceptually driven body of work that explores my obsession with irony, a need to vent frustration with public policy, complacency, and misguided priorities. The work springs from a notion to create proposals for architectural projects that are rather absurd and could never really be realized. They are my brand of visionary architecture, existing somewhere between the Utopian and the Dystopian. I have developed a vocabulary …

How Modes Of Interviewing Affect Self-Disclosure, Sara Elizabeth Nicholls

Theses

This study examined how different modes of interviewing affect the self-disclosure of sensitive information in emerging adults. Participants included 61 students ages 18 to 22 years old who attended a Western New York university. Internalizing behaviors such as feelings of depression and anxiety were measured using three questionnaire formats: face-to-face, computer, and paper/pencil. Results showed that participants answered significantly different between the interview modes on 6 of the 21 questions. Those in the computer group were significantly more likely to endorse "No" on questions pertaining to feelings of depression and anxiety. These results suggest that the computer mode may be …

Model Evaluation And Measurement Optimization For The Reproduction Of Artist Paint Surfaces Through Computer Graphics Renderings, Ying Chen

Theses

Light reflection models for computer graphics have been developed over the past several decades. For real paint surfaces, it is possible to model their bidirectional reflectance distribution function with simple models. A framework was established to evaluate two simple reflection models, Phong and Torrance-Sparrow, which were used to render artist paint surfaces under different illumination angles. An image acquisition system was devised to capture the images under selected illuminated angles. The parameters of the specular and the diffuse components were estimated with these image sequences. At the evaluation stage, both physicallybased metrics and psychophysical techniques were used to evaluate the …

Si Dios Quiere ..., Katrina Marcelle D'Autremont

Theses

This thesis explores issues of closeness and distance within families. By looking at how aspects of cultural identity further complicate this dynamic as well as how photography is used as a way of mapping a family character, this thesis encompasses topics ranging from Argentine artists to early daguerreotype photography. Using her own Argentine- American heritage as a subject for the photographs, the artist focuses on her grandfather's apartment in Argentina, which acts as a stage, and character in her family story. Traditional modes of photographic posing are borrowed and explored in this work, not only to reference the old photographs …

School Days, Hope Rovelto

Theses

My thesis exhibition, 'School Days,' is a collection of autobiographical sculptures. My thesis is inspired by the difficult memories of my childhood education. During school I felt condescension from my teachers and peers; I felt like I was actually wearing a dunce cap. This body of work represents the feeling of being ostracized from others in a classroom. I used the form of school chairs for my sculpture. The school chairs are the primary metaphor reflecting my early formal education. We, western industrial society, have an almost universal relationship with the school chair. As an artist, I use its form …

The Effects Of Writing About Positive Reminiscence On Happiness With Adolescents, Alison M. Senter

Theses

Much research has been done with adults in the field of positive psychology, reminiscence, and journal writing. Previous findings reveal that reminiscing about positive memories enhances one's happiness, well-being, life satisfaction, and self-continuity. The current study sought to expand this to adolescence. A group of 19 male and female ninth graders from a northeastern, suburban high school were assigned to a positive reminiscence or a daily hassles journal writing group. Analyses revealed significant effects on participants' positive affect; journal writing in general and specifically writing only about positive memories both significantly increased participants' ratings of perceived positive affect. However, no …

Removal Of Manganese From An Alkaline Mine Drainage Using A Bioreactor With Different Organic Carbon Sources, Jared D. Edwards

University of Kentucky Master's Theses

The treatment of Mn and SO₄^2- contaminated mine drainage via a sulfate reducing bioreactor is expected to result in near-permanent immobilization of significant amounts of Mn and a portion of the sulfates within the matrix. This study tested several different combinations of organic amendments and inorganic substrates in an attempt to optimize sulfate reducing conditions and Mn removal capacity. Five different organic carbon sources, including corn mash, wood mulch, biosolids, soybean oil, and sorghum syrup in combination with five different inorganic substrates, including creek sediment, marble and limestone chips, polished gravel, and sand were tested in batch experiments. …

The visual depictions of these costs are represented using ArcGIS in an attempt to aide farmers in further decision making. Results will show that cost maps have great possibilities in their addition to the set of tools that farmers use in decision making. This thesis will expand the understanding of lightbar from a partial budget study to a whole farm model incorporating competition across different enterprises for labor and capital. The results from the …

The Missing Link: Marital Virtues And Their Relationship To Individual Functioning, Communication, And Relationship Adjustment, Amanda Veldorale-Brogan

University of Kentucky Master's Theses

Relationship adjustment research is being expanded beyond established connections with communication and individual functioning. In recent years, researchers have looked to positive psychology and virtues. That research shifts the focus from psychopathology and communication to more core values and ways of being. The present study seeks to expand this knowledge base using Blaine Fowers (2000) framework of marital virtues. His framework views what a person puts into an intimate relationship as an important predictor of relationship adjustment. The present study uses this framework in conjunction with previous research to examine the direct and indirect links amongst individual functioning, marital virtues, …

Irritability, Executive Functioning, And The Alcohol-Aggression Relation, Aaron John Godlaski

University of Kentucky Master's Theses

The purpose of this investigation was twofold. First, to test the hypothesis that irritability and executive functioning (EF), two previously established risk factors for alcohol-related aggression, would interact to conjointly confer multiplicative risk for intoxicated violence that is not observed when testing either variable alone. Second, to test the hypothesis that irritability would mediate the relation between EF and alcohol-related aggression. EF was measured using seven well-established neuropsychological tests. Irritability was measured using the Caprara Irritability Scale-CIS. Participants were 310 male and female social drinkers between the ages of 21 – 35 years old. After consuming an …

An Evaluation Of Earthquake Ground-Motion Site Effects At Two Sites Underlain By Deep Soils In Western Kentucky, Jonathan Larry Mcintyre

University of Kentucky Master's Theses

Six earthquake acceleration time histories were used to evaluate the groundmotion response of two sites, VSAP and VSAS, near the New Madrid Seismic Zone. These earthquakes ranged in magnitude from M_w 3.6 to M_w 5.2 and were located 46 to 173 km away from the recording instruments. These two sites are underlain by thick sequences (100 and 590 m) of unlithified soil that have been shown to greatly influence earthquake ground motions.

Near-surface soil dynamic properties were characterized at the two sites using seismic SH-wave refraction, P-S suspension logging, borehole electrical logs, and geotechnical logging methods. The soil …
