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 work presents a novel comprehensive effort to understand the fluid dynamics within orbiting dishes and the effects of the resulting oscillating fluid flow on shear and endothelial cellular responses within the dishes. It is well documented...
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...
The area of total coloring is a more recent and less studied area than vertex and edge coloring, but recently, some attention has been given to the Total Coloring Conjecture, which states that each graph's total chromatic number xT is no greater...
The advent of larger storage spaces, affordable digital capturing devices, and an ever growing online community dedicated to sharing images has created a great need for efficient analysis methods. In fact, analyzing images for the purpose of...
The field of graph theory has been indubitably influenced by the study of planar graphs. This thesis, consisting of five chapters, is a historical account of the origins and development of concepts pertaining to planar graphs and their...

The client flow of the Kentucky Cabinet for Health and Family Services is a complex process that deals with a high volume of clients on any given beginning half of the month. A simulation model of an average busy day in the system was built using...
A common research interest in medical, biological, and engineering research is determining whether certain independent variables are correlated with the survival or failure times. Standard statistical techniques cannot usually be applied for...
In this study, the author examined the relationship of probability misconceptions
to algebra, geometry, and rational number misconceptions and investigated the potential
of probability instruction as an intervention to address misconceptions in all...
The term "promiscuity" is often used in academic literature and pejoratively
proliferated among society at large. The definition of promiscuity has not been clearly
and consistently defined within research and varies significantly from...
The phase II clinical trial is a critical step in the drug development process. In the oncology setting, phase II studies typically evaluate one primary endpoint, which is efficacy. In practice, a binary measurement representing the response to the...

Healthy for Life is a relatively new University of Louisville medical clinic which attempts to stem the epidemic of childhood obesity. This program offers a range of face-to-face services for overweight children. The main problem addressed by this...
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...
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...
Homeless persons--Services for--Kentucky--Louisville; Homelessness--Kentucky--Louisville; Inmates of institutions; Community-based social services--Kentucky--Louisville
The purpose of this study was to examine the link between various aspects of service utilization and the institutionalization of homeless individuals. The researcher wished to determine whether participation in various therapeutic, medical, and...
Recent advances in high throughput methodologies offer researchers the ability to understand complex systems via high dimensional and multi-relational data. One example is the realm of molecular biology where disparate data (such as gene sequence,...
The Adoption and Safe Families Act created specific outcomes for permanency for children in foster care. The purpose of these outcomes is to decrease the number of children in long term foster care. Seven years have passed since ASFA was signed...
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...
Representing the complex data in a concise and accurate way is a special stage in data mining methodology. Redundant and noisy data affects generalization power of any classification algorithm, undermines the results of any clustering algorithm and...
Web search engines; Automatic abstracting; Graph theory--Data processing
After a user types in a search query on a major search engine, they are presented with a number of search results. Each search result is made up of a title, brief text summary and a URL. It is then the user's job to select documents for...
