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...
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,...
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...
Acetone--Analysis; Air quality monitoring stations
Zinc oxide (ZnO) based gas sensors with sliver ion exchanged ZSM-5 (Ag+ZSM-5) zeolite overlayer were created and tested for detection of acetone vapor in air. The ZnO and Ag+ZSM-5 films were deposisted on 400µm by 400µm platinum interdigitated...
Paramount Ballroom (Shanghai, China); Architecture--China--Shanghai; Buildings--China--Shanghai; Shanghai (China)--History--20th century; Shanghai (China)--Social life and customs--20th century
The Paramount Ballroom was an innovative urban space that challenged traditional
Chinese values. In doing so it played an important role in Shanghai's modernization.
Traditional Confucian morality set very strict regulations on the social...
In July 1995, National Science Foundation Award # 9551869 funded the development of a new inter-disciplinary microfabrication course under the primary leadership of Dr. Kevin Walsh at the University of Louisville. Along with this award, the...
The thesis focuses on improving the flowrate of the Knudsen gas pump. The Knudsen pump uses thermal transpiration as the driving mechanism to pump gas. It is a motionless gas pump as the pump does not require any moving actuators for pumping. The...
G-quadruplexes are thought to have biological importance, with studies based on small molecule interactions and quadruplex-interactive antibodies demonstrating their potential for formation in vivo. One potential biological function of quadruplex...
In today's world of private information and mass communication, there is an ever increasing need for new methods of maintaining and protecting privacy and integrity of information. This thesis attempts to combine the chaotic world of cellular...
Stream riparian zones are ecotones between terrestrial and aquatic environments. Studying these areas in urban environments is important since they lie adjacent to stream water supplies. I conducted a study of riparian woody and groundcover...
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...
Symmetric piezoresistive microcantilever beams have been demonstrated in previous research to be capable of sensing the presence of surrounding gas. This occurs as the damping effect of the gas changes the beam resonance behavior. Device...
Microelectromechanical systems; Biotelemetry; Strains and stresses--Measurement
Lumbar arthrodesis or spinal fusion is usually performed to relieve back pain and regain functionality from ruptured discs, disc degenerative disease, trauma and scoliosis. Metal rods are often fixed to the spine with screws or hooks, while fusion...
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...
Blind--Education--Arithmetic; Arithmetic--Study and teaching--Data processing; Speech synthesis
The design and development of a microprocessor-controlled mathematics trainer is described. The trainer is designed primarily for a blind student, and uses synthetic speech to verbally present mathematics problems in the form of incomplete...
Digital control systems; Computer security; Process control--Computer programs; Supervisory control systems--Security measures
Supervisory control and data acquisition (SCADA) systems are networked control systems used in many critical infrastructure areas such as power water and transportation. Many of these systems continue to use legacy field devices that lack cyber...
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...
Bi-stable buckled MEMS (micro-electromechanical systems) diaphragms have a myriad of uses in the MEMS field for their large out-of-plane deflections. Buckling is a phenomenon brought upon by a compressive stress. Diaphragms are large aspect ratio,...
Orbital shakers are commonly used in the cell culture industry due to their ease of use, but the fluid dynamics of this system have not been extensively modeled as the system is difficult to quantify analytically. It is desirable to understand how...
