Given a metric space (K, d), the hyperspace of K is defined by H(K) = {F c K: F is compact, F ≠ 0}. H(K) is itself a metric space under the Hausdorff metric dH. Hyperspaces have been extensively studied by topologists since the 1970's, but the...
N-acetyltransferase 1 (NAT1) is a phase II metabolic enzyme responsible for the biotransformation of aromatic and heterocyclic amine carcinogens such as 4-aminobiphenyl (ASP). NAT1 catalyzes N-acetylation of arylamines as well as the 0-acetylation...
Characterization of the optical and electrical properties of organic solar cell materials is of prime importance to organic solar cell design. This thesis describes the use of capacitive photocurrent measurements to study the exciton generation and...
The Combinatorial Nullstellensatz can be used to solve certain problems in combinatorics. However, one of the major complications in using the Combinatorial Nullstellensatz is ensuring that there exists a nonzero monomial. This dissertation looks...
Supervisory control systems--Security measures; Computer security; Security systems
This thesis documents the successful development and testing of a more secure industrial control system field device architecture and software. The implementation of a secure field device has had limitations in the past due to a lack of secure...
A connected matching in a graph is a set of disjoint edges such that, for any pair of these edges, there is another edge of the graph incident to both of them. This dissertation investigates two problems related to finding large connected matchings...
Band directors--Attitudes; High school principals--Attitudes; Bands (Music)--Instruction and study
The purpose of this study was to survey secondary school administrator and band director perceptions regarding the implementation of Kentucky's Core Content for Assessment 4.1 (CCA 4.1) in Music in the band programs at their schools. Secondary...
This quantitative dissertation examines risk assessment and recidivism of child maltreatment to determine the relationship between child protective services provided by the Kentucky Department of Protection and Permanency and risk of harm. A chart...
This dissertation addresses two different problems: 1) coronal loop detection from solar images: and 2) salient contour group extraction from cluttered images. In the first part, we propose two different solutions to the coronal loop detection...
The use of franchise advisory boards, typically composed of franchisees and
franchisor representatives, is common practice in domestic and international franchise
systems. Because effective board collaboration requires teamwork, understanding...
Parks, Suzan-Lori. In the blood; Theaters--Stage-setting and scenery
From the moment the audience enters the auditorium the play is a mystery. They are looking for clues as to the nature of the story in which they are about to participate. The designer's job is to select what these clues are. How does the designer...
Due to the overwhelming increase in open source code, off-the-shelf software packages, third party and vendor codes, along with the ease of getting information about hacking network security systems and attacking the well known holes in security...
In this thesis self-assembled growth of Ag2Ga nano-needles on batch fabricated
micro-grippers are reported. The room temperature growth of Ag2Ga nano-needles have
been recently developed as stylus for Atomic Force Microscopy (AFM). Integration...
My recent work juxtaposes dualities such as natural/artificial, macro/micro, instantaneous/changing, and conscious/unconscious. As a process oriented artist, I enjoy creating tactile, illusionistic surfaces by building translucent layers through...
In this dissertation, we study the performance evaluation of two automated warehouse material handling (MH) technologies - automated storage/retrieval system (AS/RS) and autonomous vehicle storage/retrieval system (AVS/RS). AS/RS is a traditional...
Stringed instruments--Instruction and study; Music teachers--Kentucky
The purpose of this study was to identify the teaching techniques of current string
teachers within the Kentucky Music Education Association. Participants (N=31)
completed a 17-question survey that focused on teaching techniques they use...
Parents of children with disabilities; Communication in families; Attention-deficit-disordered children--Family relationships; Hyperactive children--Family relationships
The purpose of this study was to explore how mothers with an ADHD child living in the household perceive and manage family communication. In-depth interviews were conducted amongst nine married mothers who have an ADHD child. Three themes emerged...
Quorum sensing (Microbiology); Cellular signal transduction; Bacterial genetics
Quorum sensing in the oral pathogen Aggregatibacter actinomycetemcomitans is dependent upon the soluble signaling molecule AI-2, but it is not known how the initial detection of AI-2 is coupled to the downstream regulation of gene expression that...
The purpose of this empirical study was to examine the types of e-learning barriers and to establish the nature of relationships among (a) barriers perceived by employee e-learners in the process of starting, continuing, and completing online...
Mycobacterium tuberculosis causes the often-fatal infectious disease Tuberculosis, and infects approximately one third of the world's population. Gaining a better understanding of how these bacteria regulate gene expression for intracellular...
