Image processing; Computer vision; Pattern recognition systems
Image segmentation is one of the most important problems in image processing, object recognition, computer vision, medical imaging, etc. In general, the objective of the segmentation is to partition the image into the meaningful areas using the...
Purpose: To evaluate baseline and 3 different image enhancements for the detection of landmarks and overall perceived quality in photostimuable phosphor cephalograms. Methods: DenOptix images of 48 patients (plus 12 repeats) were presented randomly...
Oxidative stress-induced immunosuppression could be due to a decrease in CD4 + T lymphocyte activation or proliferation. 4-Hydroxynonenal (HNE), an end product of lipid peroxidation, and its protein adducts act as markers of oxidative stress. In...
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...
Blood flow--Measurement; Magnetic resonance imaging
Peripheral Arterial Disease (PAD) is a progressive atherosclerotic disorder which
is defined as any pathologic process obstructing the blood flow of the arteries supplying
the lower extremities. Moderate stenoses mayor may not be...
This dissertation describes (1) size-dependent electrochemical oxidation/stripping of gold and silver nanoparticles (NPs), (2) alloying of copper with gold nanoparticles at underpotential deposition potentials, (3) electrochemical characterization...
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...

Healthy for Life is a relatively new University of Louisville medical clinic which attempts to stem the epidemic of childhood obesity. This program offers a range of face-to-face services for overweight children. The main problem addressed by this...
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...
Nanostructured materials; Nanotubes; Nanoparticles; Drug delivery systems; Diagnostic Imaging
Nanomaterials have many intriguing applications in biology and medicine. Unique properties such as enhanced electrical properties, increased chemical reactivity and resistance to degradation, novel optical properties and comparable size to that of...
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...
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...
The vast knowledge of nucleic acids is evolving and it is now known that DNA can adopt highly complex, heterogeneous structures. Among the most intriguing are the G-quadruplex structures, which are thought to play a pivotal role in cancer...
Reperfusion of the ischemic lung causes pulmonary arteriolar vasoconstriction and reduces alveolar perfusion. Lung ischemia-reperfusion (IR) injury leads to platelet and leukocyte activation which could contribute to decreased alveolar perfusion...
Optimal trajectory generation is an essential part for robotic explorers to execute the total exploration of deep oceans or outer space planets while curiosity of human and technology advancements of society both require robots to search for...
Residential buildings account for a large portion of total energy consumption in the United States. Residential energy usage can be dramatically reduced by improving the efficiency of building envelope systems. One such method is to incorporate...
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,...
Infants--Wounds and injuries; Falls (Accidents); Neck--Wounds and injuries; Head--Wounds and injuries
The purpose of this study was to determine the risk of severe head and neck injury in short distance falls for a 12-month-old child. A series of free falls and falls from standing were experimentally simulated using an instrumented anthropomorphic...
Energy independence requires that the nation reduce its dependence on foreign oil imports. This can be achieved through electrification of transportation vehicles if proper battery technology can be developed. In addition, the renewable energy...
Chlamydia trachomatis is an obligate intracellular pathogen that utilizes a type III secretion system to enter mammalian cells and establish an intracellular niche. TARP, the translocated actin recruitment protein, is a chlamydial invasion protein...
