Three-dimensional imaging in medicine; Diagnostic imaging; Dental care
CBCT in endodontics demonstrates anatomic features in 3D that intraoral, panoramic, and cephalometric images cannot. CBCT units reconstruct the projection data to provide interrelational images in three orthogonal planes (axial, sagittal, and...
A combination of three techniques – high resolution micro computed tomography (micro CT) scanning, Archimedes-based volume fraction measurement and serial sectioning or milling – were used to determine the volume fraction, trabecular thickness,...
Cardiac mapping has become an important area of research for understanding the mechanisms responsible for cardiac arrhythmias and the associated diseases. Current technologies for measuring electrical potentials on the surface of the heart are...
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...
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,...
Graft rejection; Diagnostic imaging; Postoperative care
The fourth hand transplant recipient in Louisville lost his graft at nine months post transplant from ischemia due to severe graft arteriopathy. Conventional imaging techniques and clinical measurements, including CT angiography and measurements of...
The role of the active site tyrosine residue in the Co-C5' bond activation in the
context of adenosylcobalamin-dependent mutases has been computationally
investigated. The density functional, complete active space self-consistent field
and quantum...
This work presents a novel comprehensive effort to understand the fluid dynamics within orbiting dishes and the effects of the resulting oscillating fluid flow on shear and endothelial cellular responses within the dishes. It is well documented...
Hyaluronan (HA) is a major structural component of the ocular vitreous humor
(VH) and lipids are essential building blocks of cell membranes. However, little is known
about their possible interactions. The VH is known to undergo liquefaction...
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...
Coal-fired power plants--Environmental aspects--United States; Mercury wastes--Environmental aspects--United States
This dissertation tests whether or not mercury emissions from electric power plants are not a significant contributor to mercury measurements in rainfall and argues that the current United States (U.S.) Environmental Protection Agency (EPA)...
Vertical axis wind turbines (VAWTs) are devices to convert wind energy into electricity. Unlike horizontal axis wind turbines (HAWT) where the main rotor shaft is set horizontally, VAWTs use vertical rotor shaft. Unlike HAWTs, VAWTs can be...
Neuropsychology; Motor ability; Eye-hand coordination
Two major theoretical models, Direct Mapping and Functional Equivalence, suggest that the observation of action and imagery of action, respectively, involve activation of similar motor related areas. Despite the wealth of evidence that supports...
It is not the primary purpose of this present work to treat the problem of the evolution of behavior, but rather to give an analysis of animal behavior as observed. These observations may appear as simple tests, but they make possible a new way to...
The process of designing the settings and lighting for a show is an adventure; it's a story that has the normal components of any good story, a beginning, middle and end. There is tension, conflict, climax and resolution. It contains characters who...
"Here Morris presented a small rectangular structure with a door shaped as a letter 'I'. When opened the door gave on to a photograph of the artist, his phallus rhyming with the "I" connotative both of the viewers looking (eye) and...
