Adaptive Nonlinear Optimization Methodology For Installed Capacity Decisions In Distributed Energy/Cooling Heat And Power Applications., Carl Randolph Hudson

Doctoral Dissertations

Evaluation of potential cooling, heating and power (CHP) applications requires an assessment of the operations and economics of a particular system in meeting the electric and thermal demands of a specific end-use facility. Given the electrical and thermal load behavior of a facility, the tariff structure for grid-supplied electricity, the price of primary fuel (e.g., natural gas), the operating strategy and characteristics of the CHP system, and an assumed set of installed CHP system capacities (e.g., installed capacity of prime mover and absorption chiller), one can determine the cost of such a system as compared to reliance solely on traditional, …

Ac Loss And Thickness Dependence Of Critical Currents In Coated Conductors, Anota Oluwatoyin Ijaduola

Doctoral Dissertations

This program of research is directed toward understanding the physical properties of certain materials in superconductive “coated conductors.” Specifically investigated were Ni1−xWx alloys for use as substrate and thin films of YBa 2Cu3O7, a high- Tc superconductor with many attractive features. A study has been conducted on the magnetic properties of a series of biaxially textured Ni1−xWx materials with compositions x = 0, 3, 5, 6, and 9 at.% W. These materials are important as substrates for “RABiTS”-type coated conductors that incorporate high temperature superconductors for current transport. The quasi-static dc and ac …

The Rrnat/Rdna Ratio As A Measure Of Nitrite Oxidizing Activity, Shawn A. Hawkins

Doctoral Dissertations

A bench scale nitrification reactor (BSNR) containing nitrite oxidizing bacteria (NOB) of the genus Nitrobacter (» 1 × 10¹⁰/L; 5 - 22% of bacteria) was used to assess the ribosomal RNA transcript (rRNAt) to ribosomal RNA gene (rDNA) ratio as an in-situ nitrite oxidizing activity metric. A quantitative PCR detection system was developed that amplified a 143 base pair sequence within the Nitrobacter spp. 16S - 23S intergenenic spacer region. The resulting real-time PCR (rDNA) and real-time RT-PCR (rRNAt) assays were specific, accurate, and sensitive, requiring three replicate nucleic acid extracts to reliably detect a true 2-fold concentration …

Ligand Binding Studies In R67 Dihydrofolate Reductase And The Evaluation Of The Anion-Quadrupole Interaction At A Quantum Mechanical Level, Michael Robert Jackson

Doctoral Dissertations

Dihydrofolate reductases (DHFR) are important, ubiquitous enzymes catalyzing the hydride transfer from NADPH to dihydrofolate and producing the tetrahydrofolate intermediate that is essential for many metabolic processes, particularly for its role in DNA synthesis. R67 DHFR is a plasmid encoded enzyme that confers resistance to the antibiotic drug trimethoprim. This enzyme is active as a homotetramer. The active site pore possesses 222 symmetry as a result. This symmetry gives rise to a different mechanism by which it binds its ligands. There are potentially four symmetry related binding sites, but various studies have indicated only three possible combinations that include: two …

Photo-Acoustic Analysis Of Dental Materials And Tissue, Pavlina Jetchkova Jeleva

Doctoral Dissertations

The goal of the presented study is the investigation of the feasibility of using optically generated acoustic waves for analysis of dental material below laser-ablation threshold.

The temperature rise of dental material and tissue has been modeled analytically and numerically, and measured experimentally. Following interactions with nano- and femto-second laser radiation the temperature rises at a rate of typically 1 ±C per J=cm2, along with the generation of an acoustical wave. The results from the models agree with the experiment. The acoustic measurements show differences in the acoustic signal strength and the frequency spectrum when the canal in the …

The Effect Of Ultrasonic Vibration On The Solidification Of Light Alloys, Xiaogang Jian

Doctoral Dissertations

This exposition presents the novel thermodynamical and microstructural modification to light alloys, such as aluminum alloys and magnesium alloys, by ultrasonic vibrations during their solidification processes. Ultrasonic vibration has proven to be effective in controlling columnar dendritic structure, reducing the size of equiaxed grains, and under some conditions, producing globular non-dendritic grains. Despite this, the solidification process under the effect of ultrasonic vibration was not clear. Not only was there no such research on how ultrasonic vibration affected its solidification thermodynamically, but also its effects on the as-cast microstructure, including the primary fcc phase, the eutectics, and the secondary phases, …

Experimental, Theoretical, And Device Application Development Of Nanoscale Focused Electron-Beam-Induced Deposition, Steven Jeffrey Randolph

Doctoral Dissertations

To elucidate the effects of beam heating in electron beam-induced deposition (EBID), a Monte-Carlo electron-solid interaction model has been employed to calculate the energy deposition profiles in bulk and nanostructured SiO₂. Using these profiles, a finite element model was used to predict the nanostructure tip temperatures for standard experimental EBID conditions. Depending on the beam energy, beam current, and nanostructure geometry, the heat generated can be substantial. This heat source can subsequently limit the EBID growth by thermally reducing the mean stay time of the precursor gas. Temperature dependent EBID growth experiments qualitatively verified the results of the …

Pb1607 Landowner's Guide To Timber Sale Contracts, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

A written timber sale agreement or contract is generally the preferable and safest method of selling timber. A written contract is a legally binding document that protects both the buyer and the seller (the landowner) from misunderstandings that may develop in the absence of such an agreement. A contract will verify the seller’s ownership of the timber to be sold and the absence of liens or other liabilities. There is little legal recourse with verbal agreements. By negotiating a contract, both parties are likely to work out difficulties before they occur and be more pleased with the transaction.

The Only Way Out Is To Die: Perceptions And Experiences Of Rural, Homebound, Older Diabetics, Sharon Robbins George

Doctoral Dissertations

The purpose of this phenomenological study was to investigate the meaning of diabetes, as perceived and experienced by rural, homebound, 65-year and older, diabetics requiring insulin. The sixty-five year and older persons are disproportionately affected by diabetes. They are more likely than younger diabetics to have co-morbidities, disabilities and difficulty preventing diabetic complications. Guidelines for diabetes management and treatment developed by the American Diabetes Association are not specifically targeted for the 65-year and older population. Phenomenological research was used to examine and describe the understanding of diabetes from perspectives of older diabetics.

Perspectives On Self-Immolation Experiences Among Uzbek Women, Elizabeth Ann Campbell

Doctoral Dissertations

The purpose of this study was to examine the motivation of Uzbek women who committed acts of self-immolation and survived. The study examined the role of the religion and culture of Islam, whether the act of self-immolation was a suicide attempt or an act of protest, and whether the use of fire had some symbolic significance. Self-immolation, or deliberate self-burning, is increasingly becoming a cause of death and disability among young Muslim women in the Middle East andCentral Asia. However, little is known about this phenomenon.

This was a qualitative, bounded case study, which used a blended model of case …

An Investigation Of The Big Five And Narrow Personality Traits In Relation To Academic Performance, Craig Lancer Rogers

Doctoral Dissertations

The present study investigated the relationship between the Big Five personality traits (agreeableness, conscientiousness, emotional stability, extroversion, and openness), as well as the relationship of more narrow personality traits, with academic performance. The issue of narrow traits adding incremental validity to the Big Five in predicting academic performance was investigated, using archival data collected from 552 university students.

Results from a correlation analysis indicated that openness, conscientiousness, agreeableness, and emotional stability were all significantly related to GPA (college grade-point average), while extroversion was not related. Due to a significant gender difference in college GPA, gender interaction terms with …

Manufacturing System And Supply Chain Analyses Related To Product Complexity And Sequenced Parts Delivery, Hui Sun

Doctoral Dissertations

Mixed model assembly has been widely used in many industries. It is applied in order to effectively deal with increasing product complexity. Sequencing and resequencing on a mixed-model assembly line is also complicated by high product complexity. To improve the performance of a mixed-model assembly system and the supply chain, one can develop efficient sequencing rules to address sequencing problems, and manage product complexity to reduce its negative impact on the production system. This research addresses aspects of sequence alteration and restoration on a mixed-model assembly line for the purpose of improving the performance of a manufacturing system and its …

A Methodology For Solving The Equations Arising In Nonlinear Parameter Identification Problems: Application To Induction Machines, Kaiyu Wang

Doctoral Dissertations

This dissertation presents a method that can be used to identify the parameters of a class of systems whose regressor models are nonlinear in the parameters. The technique is based on classical elimination theory, and it guarantees that the solution for the parameters which minimize a least-squares criterion can be found in a finite number of steps. The proposed methodology begins with an input-output linear overparameterized model whose parameters are rationally related. After making appropriate substitutions that account for the overparameterization, the problem is transformed into a nonlinear least-squares problem that is not overparameterized. The extrema equations are computed, and …

Geographic Variation In Native American Anthropometrics: A Spatial Analysis Of The Boas And Gifford Datasets, Paul Christopher Dillingham

Doctoral Dissertations

In 1982, anthropometric data that had been lost for decades was rediscovered, and, with it, another chance was granted to add to our knowledge of the physical anthropology of the American Indian.

Because previous spatial analysis studies either utilized only a portion of the Boas data and either utilized no statistical analyses or were not published, a more comprehensive spatial analysis is still needed. The purpose of this study is to more comprehensively re-analyze the Boas and Gifford datasets using spatial analysis methods to discover the patterns of variation revealed by the data. The following questions using spatial autocorrelation analysis …

A Newly Identified Hantavirus: The Development Of Immunologic Diagnostic Assays And Phylogenetic Analysis For Detection And Characterization, Shawn Lee Lewis

Doctoral Dissertations

Hantaviruses are the etiologic agents of hemorrhagic fever with renal syndrome (HFRS) in Europe and Asia and hantavirus cardiopulmonary syndrome (HCPS) in the Americas. As of July 2005, 396 HCPS cases in 30 U.S. states with a 36% mortality rate have been confirmed since reporting began in 1993.

The primary rodent host of numerous U.S. hantaviruses in Peromyscus maniculatus (deer mouse) although other strains have been found in association with a district rodent host and geographical region. Reservoir hosts are asymptomatically, persistently infected and shed virus particles intermittently in urine, saliva and feces. Thus, the primary transmission route for hantavirus …

At the U.S. Department of Energy’s Hanford Site in Richland, WA nuclear processing wastes, such as Sr-90, organic chelating agents such as EDTA, Co-60, and U(VI) have been detected in the vadose zone beneath the underground storage tanks. There is concern that waste released to the vadose zone could reach the groundwater and eventually flow into the Columbia River. The goal of this paper is to provide an improved understanding of coupled hydrologic and geochemical mechanisms that influence contaminant transport in the Handford vadose zone. Disturbed sediment and undisturbed sediment cores were collected from the Environmental Restoration Disposal Facility (ERDF) …

Principals' Implementation Of Exclusion Policy In Tennessee Public High Schools, Clarence Steve Moser

Doctoral Dissertations

The exclusion of students from school has been a last-resort response that principals have chosen to correct inappropriate student behaviors. The purpose of this study was to examine student exclusion policies and principal policy implementation practices in Tennessee’s public high schools. The students considered were not suspected for any disability that would require consideration under IDEA or Section 504.

A questionnaire containing nineteen disciplinary scenarios of inappropriate student behaviors was completed by one hundred and ninety-two of Tennessee’s public high school principals. The disciplinary scenarios represented exclusion policies that would warrant the student being suspended from school.

The findings revealed …

Encosto In A Brazilian Favela, Darrell William Lynch

Doctoral Dissertations

The purpose of this dissertation is to explore the folk illness of encosto in the favela, or slum, of Pirambu in Fortaleza, Ceara, Brazil. Encosto is a term used primarily within the religious tradition of Umbanda. To be encostado literally means that someone is being "leaned on unduly" or "bothered by" another person. In the case of the folk illness, that "person" is believed to be a disincarnate spirit and the victim is said to be suffering from encosto. The spirit may be a deceased relative, an Exu or trickster spirit, or an entity sent to attack the victim by …

Ruffed Grouse Habitat Use, Reproductive Ecology, And Survival In Western North Carolina, Benjamin Colter Jones

Doctoral Dissertations

Ruffed grouse populations are lower in the Appalachians compared to the Great Lakes states, the geographic core of grouse distribution. Theories to explain lower numbers in the Appalachians include inadequate foods, lower reproduction, lower survival, and loss of habitat. To provide insight into ruffed grouse ecology in the Appalachians, habitat use, reproduction, and survival were studied on Nantahala National Forest in western North Carolina. Radiotagged grouse (n = 276) were monitored through the year. Seasonal 75% kernel home ranges (n = 172) averaged 15–59 ha across sexes, ages, and seasons. Home range size was related to habitat with …
