Mathematical imaging consists of many different applications including image segmentation, image classification, and inpainting. This work deals more specifically with image segmentation: the partition of an image into the background and the...
Pattern recognition systems; Cluster analysis; Data mining
Despite the large number of existing clustering methods, clustering remains a challenging task especially when the structure of the data does not correspond to easily separable categories, and when clusters vary in size, density and shape. Existing...
The objective of this thesis is to develop computer programs for the dynamic analysis of structures. For a shear building two computer programs were developed: (1) Dynamic Analysis of a Shear Building within the Elastic Range and (2) the Dynamic...
The classification of self-dual codes has been an extremely active area in
coding theory since 1972 [33]. A particularly interesting class of self-dual codes
is those of Type II which have high minimum distance (called extremal or...
Three main theorems due to Fenichel are fundamental tools in the exploration
of geometric singular perturbation theory. This expository paper attempts
to provide an introduction to the concepts stated in Fenichel's theorems and provide
illustrative...
The area of Knowledge discovery and data mining is growing rapidly. Feature Discretization is a crucial issue in Knowledge Discovery in Databases (KDD), or Data Mining because most data sets used in real world applications have features with...
Equations of state attempt to describe the relationship between temperature (T), pressure (P), and molar volume (v) for a given substance or mixture of substances. The ideal gas law is the simplest form of an equation of state. An ideal gas can be...
Sovereign wealth funds; International economic relations
The famous oil baron' John Paul Getty once defined his secret to success in three parts, "Rise early, work hard, strike oil." This recipe, however, has not lead to political and economic success for oil-reliant, emerging market states....
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...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. This issue says Vol. 18. No. 41. but is actually Vol. 18. No. 49. Portions of the first page of this issue are very faded.
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...
The use of a fluidized bed dryer to dry acrylo-nitrile-
butadiene-styrene terpolymer was studied. Data for
fluidized bed drying were obtained from the Monsanto
Company's fluid bed dryer. Fluid bed theory, drying
phenomena, and fluid bed drying...
Micro air vehicles (MAVs) are type of unmanned aircraft with a maximum length of 150 mm (6 in.) and flight speed of less than 10 m/s. Because their flight speed is comparable to the environmental wind speed coupled with their small size and low...
Mixed-effects model is an efficient tool for analyzing longitudinal data. The random effects in mixed-effects model can be used to capture the correlations among repeated measurements within a subject. The time points are not fixed and all...
Ground-level ozone forecast models were developed for the following middle and small metropolitan areas in Kentucky: Ashland, Bowling Green, Owensboro, and Paducah. These models were nonlinear regression models, based on models previously developed...
Ozone forecast models using nonlinear regression (NLR) have been successfully applied to daily ozone forecast for seven metro areas in Kentucky, including Ashland, Bowling Green, Covington, Lexington, Louisville, Owensboro, and Paducah. In this...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. The first page of this issue is very faded. This issue is twelve pages and is made up of the normal eight pages with an...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. There is a crease across the center of each page of this issue that has resulted in some small tears.
Hemolysis (red cells lysis) caused by fluid stresses in flows within hypodermic needles, blood pumps, artificial hearts and other cardiovascular devices, is one of the major concerns during the design and use of cardiovascular or blood-processing...
Crossover design is a type of longitudinal study with each subject receiving different treatments in different time periods. It has been used frequently in the pharmaceutical industry and other medical fields to investigate the safety and efficacy...
