Trees in cities--Kentucky--Louisville; Urban forestry--Kentucky--Louisville; Louisville (Ky.)--Environmental conditions
Trees in urban residential neighborhoods provide valuable ecosystem services. Urban trees also face threats from disturbances, such as storms. In 2008, the Urban Forest Effects model was used to estimate abundance and species composition of...
The secondary visual pathway, from the retina through the superior colliculus and pulvinar nucleus has been linked to spatial attention (Snow et aI., 2009; Arend et aI., 2008) movement planning and motor response to visual stimuli (Wilke et aI....
Stream riparian zones are ecotones between terrestrial and aquatic environments. Studying these areas in urban environments is important since they lie adjacent to stream water supplies. I conducted a study of riparian woody and groundcover...
This paper investigates the development and applications of the Black-Scholes
formula. This well-known formula is a continuous time model used primarily to price
European style options. However in recent decades, observations in financial market...
The pulvinar is the largest nucleus of the human dorsal thalamus and is affected in a variety of brain disorders, such as schizophrenia. The experiments described in this dissertation elucidate key features of tecto-pulvino-cortical pathways as a...
Medical care--Decision making; Decision making--Simulation methods
A variety of methodologies have been employed for decision making related to the treatment of diseases/injury. Decision trees are a functional way in which to examine problems under uncertainty by providing a method to analyze decisions under risk...
Current high-throughput gene expression experiments have a straightforward design of examining
the gene expression of one group or condition relative to that of another. The data is typically
analyzed as if they represent strictly intracellular...
Recently, social multimedia-sharing websites, which allow users to upload, annotate, and share online photo or video collections, have become increasingly popular. The user tags or annotations constitute the new multimedia "meta-data". We...
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 purpose of this dissertation is to find ways to decrease Medicare costs and to study health outcomes of diabetes patients as well as to investigate the influence of Medicare, part D since its introduction in 2006 using the CMS CCW (Chronic...
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...
Background: Helicobacter pylori (Hp) establishes life-long gastric infection in billions of humans, and is often responsible for diseases such as peptic ulcer and gastric cancer. Cumulative actions of genetic drift and natural selection over...
Data Classification is a task that could be found in many life activities. In general, the term could be used for any activity that derives some decision or forecast based on the currently available information. Using a more accurate definition, a...
Computer scientists studying formal languages have made use of a variety of representations to both reason, and communicate their ideas to others. Symbolic representations have proved useful for rigorously defining the theoretical objects of the...
Sensor networks are just in their infancy. Their use will continue to grow as the technology becomes cheaper and more efficient. A current shortcoming with sensor networks is the inability to efficiently provide secure communications. As sensor...
The topic of this dissertation is the automation of the process of extracting understandable patterns and rules from data. An unprecedented amount of data is available to anyone with a computer connected to the Internet. The disciplines of Data...
Nonparametric statistics; Estimation theory; Distribution (Probability theory)
Multistate models are a type of multi-variate survival data which provide a framework for describing a complex system where individuals transition through a series of distinct states. This research focuses on nonparametric inference for general...
In 2003, Wilson Creek running through Bernheim Arboretum and Research Forest in central Kentucky was restored to its original winding path through a valley field. Early 20th century settlers had previously redirected this creek to run a straight...
In recent years, a number of computational and statistical problems for identifying SNP-SNP interactions in high dimensional survival data have been studied, and several data mining approaches have been proposed. However, the relative performance...
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...
