Determining the etiology of skeletal malocclusion is an important diagnostic step in treatment planning patients with maxillofacial anomalies. Aims: To describe cranial base morphology using cone beam computed tomography (CBCT) images and correlate...
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...
For persons with disabilities, access to transportation is necessary for integration into society. The Americans with Disabilities Act (ADA) has been instrumental in assuring transportation access to individuals with disabilities for purposes of...
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...
Indians of North America--Kentucky--Bullitt County--Antiquities; Excavations (Archaeology)--Kentucky--Ashworth Rockshelter site; Ashworth Rockshelter site (Ky.)
Reinvestigation of a National Register property, the Ashworth Rockshelter (15BU236), northeast of Shepardsville, Bullitt Co., Kentucky, revealed stratified Early Archaic through Mississippian components (ca. 7900 B.C.-1500 A.D.). Primary occupation...
Traditionally, fingerprint image acquisition was based on contact. However
the conventional touch-based fingerprint acquisition introduces some problems
such as distortions and deformations to the fingerprint image. The most recent
technology for...
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...
This thesis will present various methods of trajectory generation for various types of mobile robots. Then it will progress to evaluating Robot Operating Systems (ROS’s) that can be used to control and simulate mobile robots, and it will explain...
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....
Athletic shoes; Foot--Wounds and injuries--Prevention
The purpose of this investigation was to determine if cycling shoes made with stiff material cause an increase in peak plantar stress over shoes with less stiff material. Shoe stiffness measurements were collected under controlled conditions and in...
African American men--Employment; African American men--Attitudes; Mentoring in business; Job satisfaction
This dissertation is a correlational designed study that examined the strength and direction of the relationship between mentoring, job satisfaction, and organizational commitment, of African American men, exclusively in a business setting (N =...
Wind energy conversion systems; Wind power--Technological innovations; Wind power--Research
This thesis proposes a new Maximum Power Point Tracking (MPPT) algorithm employed in Wind Energy Conversion Systems (WECS). One of the major issues discussed in the literature concerning HCS is its inefficiency in detecting the peak power when...
Introduction: The study investigated dimensional relationships between the sphenoid and maxillary sinuses and other selected craniomaxillofacial structures by using traditional cephalometric and volumetric procedures based on cone beam computed...
A blinded observational cross-sectional in vitro study was conducted to compare the diagnostic accuracy of observers viewing images made using cone beam computerized tomography (CBCT), panoramic radiography and linear tomography. The sample...
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...
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...
Influenza--United States--Management; Epidemics--Management; Health services administration; Mathematical optimization
Pandemic influenza has been an important public health concern. During the 20th century, three major pandemics of influenza occurred in 1918, 1957, and 1968. The pandemic of 1918 caused 40 to 50 million deaths worldwide and more than 500,000 deaths...
Objective . To compare the in vitro reliability and accuracy of linear measurements between cephalometric landmarks on CBCT 3D images with varying basis projection images to direct measurements on human skulls. Methods . Sixteen linear dimensions...
Estimating and analysis of deformation, either rigid or non-rigid, is an active area of research in various medical imaging and computer vision applications. Its importance stems from the inherent inter- and intra-variability in biological and...
Solar energy--Technological innovations; Electric current rectifiers
Solar energy offers a large potential as a source of energy and in light of financial
and ethical reasons, people are looking to harvest it for their energy needs. The
conversion of solar energy to electricity is performed by solar cells. There...
