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....
In this dissertation research, we aim to solve problems of two types of survival data, clustered survival data with potentially informative cluster size and sojourn time data. The methods for these two types of data are different. However, both...
Optimal trajectory generation is an essential part for robotic explorers to execute the total exploration of deep oceans or outer space planets while curiosity of human and technology advancements of society both require robots to search for...
Outerplanar graphs are planar graphs that have a plane embedding in which each vertex lies on the boundary of the exterior region. An outerplanar graph is maximal outerplanar if the graph obtained by adding an edge is not outerplanar. Maximal...
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...
Symmetric piezoresistive microcantilever beams have been demonstrated in previous research to be capable of sensing the presence of surrounding gas. This occurs as the damping effect of the gas changes the beam resonance behavior. Device...
Computer-aided minimally invasive surgery (MIS) has progressed significantly in the last decade and it has great potential in surgical planning and operations. To limit the damage to nearby healthy tissue, accurate modeling is required of the...
Osteoporosis in women--Prevention; Osteoporosis--Treatment; Hip joint--Fractures--Prevention
Low-trauma fractures of older women are a major public health burden. Fractures of the hip and spine are some of the primary causes of chronic pain, functional impairment, and disability among the elderly [1]. The underlying cause of these...
Standard regularity assumptions for regression models are not satisfied in segmented regression models with an unknown change point, and consequently standard asymptotic results and inferential methods for confidence estimation are not applicable....
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...
Aim. The efficacy of ridge preservation procedures using grafting materials and barrier membranes has been well established in the literature. However, the loss of horizontal width even with the utilization of intrasocket only guided bone...
The Faroe Islands are a small archipelago in the North Atlantic. With a current population of approximately 49,000 individuals and evidence of high levels of genetic drift, the Faroese are thought to have remained highly homogeneous since their...
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...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. Page seven of this issue is very faded.
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...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
Marginal inference for waiting times in multi-stage time-to-event models is complicated by right censoring of observations as well as the prior history of events in the model. In general, complications arise due to the evolution of the censoring...
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...
Obesity in children; Obesity in adolescence; Orthodontics
The purpose of this study was to determine if obesity impacts craniofacial dimensions in adolescent and teenage subjects. Twenty-one cephalometric measurements were selected as a basis for comparison between normal weight, overweight and obese...
