Measuring Community Consensus In Facial Characterization Using Spatial Databases And Fuzzy Logic, James Lee Mastros Jan 2005

Measuring Community Consensus In Facial Characterization Using Spatial Databases And Fuzzy Logic, James Lee Mastros

Theses and Dissertations

Spatial databases store geometric objects and capture spatial relationships that can be used to represent key features of the human face. One can search spatial databases for these objects, and seek the relationships between them, using fuzzy logic to provide a natural way to describe the human face for the purposes of facial characterization. This study focuses on community perception of short, average, or long nose length. Three algorithms were used to update community opinion of nose length. All three methods showed similar trends in nose length classification which could indicate that the effort to extract spatial data from images …

The Marinhieros Project: Roseneath Rd & Patterson Ave, Jacqueline H. Crowley

Theses and Dissertations

In questioning the very nature of a thing, at its most basic level, a new assessment can be made of what the thing in question truly is. When we ask ourselves, what is a weed, we begin to pull the word apart - to decrypt the word from the cultural baggage that has collected around it over the course of the history of language.The cultural connotations of 'weed' cling to it like barnacles, removing the word from its true value. We reevaluate meaning, chronicling all the possible constructions of a word, all the possible varieties, where it came from, what …

A Study On The Nature Of Anomalous Current Conduction In Gallium Nitride, Joshua K. Spradlin Jan 2005

A Study On The Nature Of Anomalous Current Conduction In Gallium Nitride, Joshua K. Spradlin

Theses and Dissertations

Current leakage in GaN thin films limits reliable device fabrication. A variety of Ga and N rich MBE GaN thin films grown by Rf, NH3, and Rf+ NH3, are examined with electrical measurements on NiIAu Schottky diodes and CAFM. Current-voltage (IV) mechanisms will identify conduction mechanisms on diodes, and CAFM measurements will investigate the microstructure of conduction in GaN thin films. With CAFM, enhanced conduction has been shown to decorate some extended defects and surface features, while CAFM spectroscopy on a MODFET structure indicates a correlation between extended defects and field conduction behavior at room temperature. A remedy for poor …

Myocardial Perfusion Imaging With Rb-82 Pet, George Nittil Francis Jan 2005

Myocardial Perfusion Imaging With Rb-82 Pet, George Nittil Francis

Theses and Dissertations

Myocardial perfusion imaging (MPI) is an effective technique used to study the left ventricular ejection function (LVEF), myocardial perfusion, wall motion, and wall thickening. Positron emission tomography (PET) and single photon emission computed tomography (SPECT) are two modalities that can be used to quantify the left global and regional perfusion at rest and stress. While PET and SPECT rely on similar principles to produce images, important differences in instrumentation and experimental applications are dictated by inherent differences in their respective physics of radioactive decay. With a sensitivity > 90% in combination with a high specificity, PET is today the best available …

Gustav Stickley's Hapke-Geiger House And Noland And Baskervill's Hunton House: Richmond Architecture Ca. 1915, Victoria Katsuko Carter Jan 2005

Gustav Stickley's Hapke-Geiger House And Noland And Baskervill's Hunton House: Richmond Architecture Ca. 1915, Victoria Katsuko Carter

Theses and Dissertations

Textbooks teach architecture as conveniently divided into styles and periods, but in reality styles overlap. At the turn-of-the-twentieth century there were three major architectural and decorative movements in the United States: the Aesthetic Movement, the Arts and Crafts Movement, and the American Renaissance Movement. This thesis shows how superficial stylistic labels can be by comparing two very different-seeming houses of the early twentieth century: The Hapke-Geiger House of ca. 1912 in Chesterfield, Virginia, based on a Gustav Stickley Arts and Crafts design, and the Hunton House of 19 14 in Richmond, Virginia, designed in the American Renaissance style by Noland …

Identification Of The Rna Cis-Elements That Interact With Srp30a To Regulate The Alternative Splicing Of Caspase 9 Pre-Mrna, Prabhat Mukerjee

Theses and Dissertations

Studies have shown that the alternative splicing of caspase 9 and the phospho-status of SR proteins, a conserved family of splicing factors, are regulated by chemotherapy and de novo ceramide via the action of protein phosphatase-1 (PP1). Two RNA splice variants are derived from the caspase 9 gene, pro-apoptotic caspase 9a and anti-apoptotic caspase 9b, via alternative splicing by either the inclusion or exclusion of an exon 3, 4, 5, and 6 cassette. In this study, the link between SR proteins and the alternative splicing of caspase 9 was established. Sequence analysis of the exon 3, 4, 5, and 6 …

Dual Mechanism Analgesia-Enhancing Agents, Shawquia Elithia Young Jan 2005

Dual Mechanism Analgesia-Enhancing Agents, Shawquia Elithia Young

Theses and Dissertations

Currently, there is an increasing need for novel analgesics that are potent but lack undesired side effects. Recent studies have shown that both 5-HT3 receptors and α2B- adrenoceptors play a role in antinociception. MD-354, N-(3-chlorophenyl)guanidine, has a high-affinity both for 5-HT3 and α2B- adrenoceptors and could be viewed as the first example of a rather selective 5-HT3/α2B- adrenoceptor ligand. MD-354, inactive by itself, potentiates the antinociceptive effects of an inactive dose of clonidine in the mouse tail- flick assay. An attempt to determine the underlying mechanism of this potentiating effect was the purpose of the present investigation. The studies focused …

Feedback Stabilization Of Inverted Pendulum Models, Bruce Cox Jan 2005

Feedback Stabilization Of Inverted Pendulum Models, Bruce Cox

Theses and Dissertations

Many mechanical systems exhibit nonlinear movement and are subject to perturbations from a desired equilibrium state. These perturbations can greatly reduce the efficiency of the systems. It is therefore desirous to analyze the asymptotic stabilizability of an equilibrium solution of nonlinear systems; an excellent method of performing these analyses is through study of Jacobian linearization's and their properties. Two enlightening examples of nonlinear mechanical systems are the Simple Inverted Pendulum and the Inverted Pendulum on a Cart (PoC). These examples provide insight into both the feasibility and usability of Jacobian linearizations of nonlinear systems, as well as demonstrate the concepts …

Memories We Forget, Michael Dax Iacovone Jan 2005

Memories We Forget, Michael Dax Iacovone

Theses and Dissertations

I have always preferred the journey to the destination. When I was growing up, my family drove back and forth between Florida and New York every summer. My father did the driving, my mother sat next to him, and my older brother and sister sat in the back seat. This left the cavernous back of the family station wagon for me and the luggage. There was no radio, very little conversation, and I didn't sleep. I spent these summer trips staring for endless hours, out of the back window of the car, transfixed on the expanse of open road behind …

Intracellular Ph, The Proximate Signal For Cell Volume Changes That Are Mediated By The Actin Cytoskeleton, William Pasley Jan 2005

Intracellular Ph, The Proximate Signal For Cell Volume Changes That Are Mediated By The Actin Cytoskeleton, William Pasley

Theses and Dissertations

The relationship between initial intracellular pH (pHi) and associated cell volume change was investigated by simultaneous measurement of pHi and cell volume with fluorescence imaging in polarized fungiform taste receptor cells (TRCs) loaded with BCECF in vitro. Ammonium pulses caused a brief, reversible alkalinization in pHi and induced cell swelling. Sodium-acetate pulses reversible decreased TRC pHi and induced cell shrinkage. Removal weak acids and return to Control Ringer's solution (CR) causedTRC pHi and volume to overshoot baseline levels before fully recovering. Replacing CR with zero-sodium solution resulted in irreversible acidification of TRC pHi and induced cell swelling. Addition of sodium …

Afm And C-Afm Studies Of Gan Films, Katherine Cooper Jan 2005

Afm And C-Afm Studies Of Gan Films, Katherine Cooper

Theses and Dissertations

This thesis uses the techniques of atomic force microscope (AFM) and conductive AFM (C-AFM) to study the conduction properties of n-type GaN films. A total of 16 samples were examined and grouped according to their surface morphologies and conduction behaviors. The most common type of surface morpliology was that of Ga-rich samples having undulating "hillocks" with interspersed holes. Although most of the samples had this common morphology, their local conduction behaviors were not all similar. Local I-V spectra of the tip-sample Schottky contact could be grouped according to three major types: low leakage, high leakage, and "p-type". The highest quality …

Status Epilepticus Results In A Duration-Dependent Increased Protein Kinase A Activity In The Rat Pilocarpine Model, James M. Bracey Jan 2005

Status Epilepticus Results In A Duration-Dependent Increased Protein Kinase A Activity In The Rat Pilocarpine Model, James M. Bracey

Theses and Dissertations

This study was conducted to characterize cellular changes occurring during the progression of status epilepticus (SE) that could lead to the maintenance of increased membrane excitability. SE was induced by injection of pilocarpine after which rats were monitored both electrographically and behaviorally. After various lengths of time in SE, specific brain regions were isolated for biochemical study. SE resulted in an early maintenance of PKA activity in both cortical homogenate and crude synaptoplasmic membrane (crude SPM) fractions. At subsequent stages of SE there was a significant increase in PKA activity in both homogenate and crude SPM fractions. Wester blot analysis …

Assessing The Effects Of Momentary Priming On Memory Retention During An Interference Task, Paul Cameron Schutte Jan 2005

Assessing The Effects Of Momentary Priming On Memory Retention During An Interference Task, Paul Cameron Schutte

Theses and Dissertations

A memory aid, that used brief (33ms) presentations of previously learned information (target words), was assessed on its ability to reinforce memory for target words while the subject was performing an interference task. The interference task required subjects to learn new words and thus interfered with their memory of the target words. The brief presentation (momentary memory priming) was hypothesized to refresh the subjects' memory of the target words. 143 subjects, in a within subject design, were given a 33ms presentation of the target memory words during the interference task in a treatment condition and a blank 33ms presentation in …

Intelligent Autonomous Data Categorization, Edward Graham Finegan Jan 2005

Intelligent Autonomous Data Categorization, Edward Graham Finegan

Theses and Dissertations

The goal of this research was to determine if the results of a simple comparison algorithm (SCA) could be improved by adding a hyperspace analogue to language model of memory (HAL) layer to form NCA. The HAL layer provides contextual data that otherwise would be unavailable for consideration. It was found that NCA did improve the results when compared to SCA alone. However, NCA added complexity problems that limit its practicality. The complexity of this algorithm is On3 where n is equal to the number of unique symbols in the data. While there is a relativity reasonable soft upper bound …
