Evaluating Sensorineural Hearing Loss With An Auditory Nerve Model Using A Mean Structural Similarity Measure, Andrew Hines, Naomi Harte

Conference papers

Hearing loss research has traditionally been based on perceptual criteria, speech intelligibility and threshold levels. The development of computational models of the auditory-periphery has allowed experimentation via simulation to provide quantitative, repeatable results at a more granular level than would be practical with clinical research on human subjects. This work seeks to create an objective measure to automate this inspection process and ranks hearing losses based on auditory-nerve discharge patterns. A systematic way of assessing phonemic degradation using the outputs of an auditory nerve model for a range of sensorineural hearing losses would aid in rapid prototyping development of speech-processing …

An Evaluation Of The Effectiveness Of Corporate Communication During Large-Scale Information Technology Changes, Dawna M. Drum

All-Inclusive List of Electronic Theses and Dissertations

The success rate of information technology implementations remains low, despite decades of scholarly research and popular advice. Whether success is defined by spending within the budget, on-time completion, functionality of the final implementation, or satisfaction of the users, few projects are deemed to be complete and resounding successes. One possible reason is inadequate communication during the change process, and many studies have examined aspects of change communication such as media choice, message content, and timing of the messages. What has been missing, however, is an assessment of these items‟ effectiveness across hierarchical levels within an organization undergoing an important technology …

Physiological Responses To Temperature In The Lizard, Sceloporus Undulatus, Joseph C. Ehrenberger

All-Inclusive List of Electronic Theses and Dissertations

Temperature affects all organisms differently. Physiological processes, such as metabolism, interact with temperature to determine a minimal rate of energy loss. Physiological limits, such as heat and cold tolerances, likely constrain the activity and survival of organisms. Ultimately, these physiological processes and limits determine a species' geographical distribution. Through experiments, I sought to understand specifically how temperature affects the physiology of the lizard Sceloporus undulatus. This species is a model organism to answer such questions, as it is geographically widespread species and well-described phylogenetically. In the first experiment, I compared standard metabolic rates of lizards from three locales and interpreted …

Transgenic Manipulation In Zebra Fish By Combination Of Cre-Loxp Recombinant System, Tol2 Transposon System, And Rnai Technique, Yang Bai

All-Inclusive List of Electronic Theses and Dissertations

The overall goal of this research is to make precisely controlled transgene constructs to target genes in zebrafish and facilitate their functional studies. Many of the previous transgenic techniques (e.g. morpholino) can only produce transient gene expression or inhibition, which is not good for long-term studies. Also, transgenes that randomly integrate into the chromosomes are typically difficult to control and are poorly regulated. Thus, it would be of great benefit to develop a reversibly controlled transgenic tool to help study gene function. Here, we propose to combine three distinct techniques to generate a stable transgenic tool to facilitate gene functional …

Distraction Osteogenesis In An Organ Culture Model, Bradley R. Heil

University of Kentucky Master's Theses

Distraction osteogenesis (DO) is a surgical procedure in which applied strain stimulates new bone growth; however, the underlying mechanisms by which bone cells respond to load are still uncertain. An organ culture model of DO was developed and validated by using linear distraction on the femoral shafts of 5 day old Wistar rats. Two loading regimes were utilized: distracting the bones for 2 hrs on day 1 (GRP I); distracting the bones for 2 hrs on days 1, 3, and 5 (GRP II). After 1 week in culture, the bones were compared to unloaded contralateral controls and assessed for changes. …

Theoretical Modeling And Analysis Of Ammonia Gas Sensing Properties Of Vertically Aligned Multiwalled Carbon Nanotube Resistive Sensors And Enhancing Their Sensitivity, Shripriya Darshini Poduri

University of Kentucky Master's Theses

Vertically aligned Multiwalled Carbon Nanotubes (MWCNTs) were grown in the pores of Anodized Aluminum Oxide (AAO) templates and investigated for resistive sensor applications. High Sensitivity of 23% to low concentration (100 ppm) of ammonia was observed. An equivalent circuit model was developed to understand the current flow path in the resistive sensor. This helped us in achieving high sensitivities through amorphous carbon (a-C) layer thickness tailoring by employing post-growth processing techniques like plasma etching.

A simulation model in MATLAB was developed to calculate the device resistance and the change in the sensitivity as a function of device parameters. The steady …

Accuracy Of Real Time Radiography Burning Rate Measurement, Bisola Olaniyi

Theses

The design of a solid propellant rocket motor requires the determination of a propellant's burning-rate and its dependency upon environmental parameters. The requirement that the burning-rate be physically measured, establishes the need for methods and equipment to obtain such data. A literature review reveals that no measurement has provided the desired burning rate accuracy. In the current study, flash x-ray modeling and digitized film-density data were employed to predict motor-port area to length ratio. The pre-fired port-areas and base burning rate were within 2.5% and 1.2% of their known values, respectively. To verify the accuracy of the method, a continuous …
