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...
In order to study the movements of autonomous mobile robots, a tool is needed to quantify those movements. A testbed is an apparatus that provides a designated space for multiple mobile robots while tracking their position in real-time. That...
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...
A projected high penetration of battery electric vehicles (BEV s) in the market will introduce an additional load in the electricity grid. Furthermore, uncontrolled BEV charging from residential users will exacerbate the existing peak load during...
School employees--discipline; Labor laws and legislation--United States; Privacy, Right of--United States; Labor discipline--United States
The right to discipline a P-12 public school employee for off-duty conduct remains unclear. Historically, society has held teachers up to a higher standard of conduct than persons in most other professions. The researcher traced the...
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...
Computer vision; Pattern recognition systems; Human face recognition (Computer science)
Humans have the uncanny ability to perceive the world in three dimensions (3D), otherwise known as depth perception. The amazing thing about this ability to determine distances is that it depends only on a simple two-dimensional (2D) image in the...
From a computerized image analysis prospective, early diagnosis of lung cancer involves detection of doubtful nodules and classification into different pathologies. The detection stage involves a detection approach, usually by template matching,...
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...
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...
Various vision tasks are usually confronted by appearance variations due to changes of illumination. For instance, in a recognition system, it has been shown that the variability in human face appearance is owed to changes to lighting conditions...
Radio frequency allocation--Mathematics; Wireless communication systems--Mathematical models; Frequency spectra--Mathematical models
Multidimensional frequency estimation is a classic signal processing problem that has versatile applications in sensor array processing and wireless communications. Eigenvalue-based two-dimensional (2-D) and N -dimensional ( N -D) frequency...
Wound healing--Research; Wound healing--Animal models; Rabbits as laboratory animals
Ventral ear skin of the rabbit is a commonly used model for wound/ulcer studies; however the gradient effects of vascular ligation on epidermal stability has not been reported. In this study ischemic effects were studied after ligation of the...
This dissertation addresses two different problems: 1) coronal loop detection from solar images: and 2) salient contour group extraction from cluttered images. In the first part, we propose two different solutions to the coronal loop detection...
Athletic cleated shoe failures are commonplace to competitive-level ultimate
frisbee players. Currently, there are no athletic cleated shoes designed for the sport of
ultimate frisbee; players generally choose between football or soccer cleated...
In fulfillment of the thesis project requirement for the Master of Fine Arts Degree at the University of Louisville, I portrayed the role of Paulina in William Shakespeare's The Winter's Tale. The production was directed by Dennis Krausnick,...
Data encryption (Computer science); Computer networks--Security measures
This thesis describes a method of gaining better
performance from the Blowfish cryptographic algorithm using
GPU acceleration via CUDA (Compute Unified Device
Architecture). It is an attempt to resolve the issue of
the cryptographic process taking...
Experiential learning; College students--Medical care; Interns (Medicine)
This exploratory study was conducted using a descriptive design and examined the use of college health centers for academic internships and clinical rotations. In addition, the study examined the relationship among health center director and school...
Writing centers; English language--Rhetoric--Study and teaching (Higher); Tutors and tutoring
Using Gloria Anzuldula's text Borderlands/La Frontera: The New Mestiza and Bruce Homer and Min-Zhan Lu's 2000 article, "Expectations, Interpretations and Contributions of Basic Writing" as conceptual framework, I conducted my dissertation...
Evidence suggests that cortical minicolumns are reduced in size and increased in number in individuals with autism spectrum disorder (ASD), especially in the dorsolateral prefrontal cortex (DLPFC). More specifically minicolumns in individuals with...
