Nanoparticles are a class of materials that exhibit unique physical and chemical properties compared to those of the same material at the bulk scale. One method of enhancing the thermal conductivity, and hence the heat transfer coefficient, of a...
Modular hip implants are currently being used in total hip arthroplasty revision procedures because it is common to have little or no bone left in the proximal region of the femur and it is difficult to accurately size implants based off of...
We formulate an integro-difference model to predict the growth and spatial
spread of a perennial plant population with an age-structured seed bank. We allow
the seeds in the bank to be of any age, producing an infinite system of equations.
The...
Many businesses have poor IT infrastructure and are in need of a major overhaul. University of Louisville Properties (ULP), in particular, needed the ability to share files between staff, backup data, secure data, and eliminate viruses and malware....
This dissertation describes research focused on the synthesis, polymerization and
applications of cationic aminooxy lipids. An efficient and convenient method was
developed to stabilize liposomes using 'click chemistry'. The 'click...
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...
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...
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...
Cardiac mapping has become an important area of research for understanding the mechanisms responsible for cardiac arrhythmias and the associated diseases. Current technologies for measuring electrical potentials on the surface of the heart are...
This dissertation describes (1) size-dependent electrochemical oxidation/stripping of gold and silver nanoparticles (NPs), (2) alloying of copper with gold nanoparticles at underpotential deposition potentials, (3) electrochemical characterization...
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
Integrated circuits--Design and construction; Integrated circuits industry--Technological innovations
Lithographic processes for printing device structures on integrated circuits plays a major role in the semiconductor industry. This project aims at designing and fabricating a programmable mask for a direct write lithography system which can...
The separation of C02 from light gases is a very important environmental and energy issue. The state-of-the-art process for the purification of C02 uses amine adsorption, which is a complex, and costly. Membrane technology is far less expensive...
Bioinformatics; Breast--Cancer--Treatment; Medical care--Data processing
Statistical models have been the first choice for comparative effectiveness in clinical research. Though effective, these models are limited when the data to be analyzed do not fit the assumed distributions; which is mostly the case when the study...

Because of the anonymity that P2P networks provide, they are an ideal medium for
the exchange of contraband material such as child pornography. Unfortunately, not
much research has been conducted on how to best monitor these types of networks
for...
Orbital shakers are commonly used in the cell culture industry due to their ease of use, but the fluid dynamics of this system have not been extensively modeled as the system is difficult to quantify analytically. It is desirable to understand how...
This research will look at a printing operation that prints labels for paint cans. This particular printing operation is a multi-product, single-machine system with stochastic demands that uses a printing press to print the labels on large sheets...
Images, Photographic--Databases; Image processing--Digital techniques; Data mining; Cluster analysis
The performance of content-based image retrieval systems has proved to be inherently constrained by the used low level features, and cannot give satisfactory results when the user's high level concepts cannot be expressed by low level features. In...
