Scene matching between a quantitative map and a qualitative hand drawn sketch
(University of Missouri--Columbia, 2007)
The goal of this work is to perform scene matching between a sketched map and the scene depicted by the sketch, e.g., as represented by a precise physical map or an occupancy grid map (OGM) built by a robot. In this thesis, ...
Spectroscopic ellipsometry analysis of nanoporous low dielectric constant films processed via supercritical carbon dioxide for next-generation microelectronic devices
(University of Missouri--Columbia, 2007)
My research will address issues at the back-end-of-line in microelectronics fabrication, specifically the need for Low-k extendibility. The International Roadmap for Semiconductors (2005) suggested that interconnect insulation must be replaced...
Improved contact design for the SiC photo-switch used in high power applications
(University of Missouri--Columbia, 2007)
-switch may not be realized. Reported in this paper is a novel concept of inserting contoured electrodes into the SiC bulk to minimize field crowding in order to improve the breakdown characteristics. The concept is simulated, a fabrication process is designed...
Electromagnetic effects on soybeans
(University of Missouri--Columbia, 2007)
In this study we have exposed different varieties of soybean seeds to electromagnetic (EM) radiation at a frequency other than that of light. The objective was to determine changes in the germination rate, if any, under ...
A MEMS based Coulter counter for cell sizing
(University of Missouri--Columbia, 2007)
Detection and classification of cells forms an important aspect of medical research in diagnosing diseases and finding remedies at the cellular level. Miniaturized cell detecting devices are desirable not only for on site ...
The development of electrohydraulic steering control system for off-road vehicle automatic guidance

A biologically inspired optical flow system for motion detection and object identification
(University of Missouri--Columbia, 2007)
Optical flow is possibly the best known method for motion segmentation. However its application is restricted to offline processing as it requires extensive computational resources and time. This thesis explores an optical ...
The spatial cross-correlation coefficient as an ultrasonic detection statistic
(University of Missouri--Columbia, 2007)
In ultrasonics, image formation and detection are most commonly based on signal amplitude. Matched filtering is an amplitude independent approach, but requires accurate template estimation. In this work, we introduce the ...
Embedded system design and power-rate-distortion optimization for video encoding under energy constraints
(University of Missouri--Columbia, 2007)
The portable devices used in video communication application are powered by batteries. Video encoding schemes, however, are often computationally intensive and energy-demanding, even after being fully optimized with existing ...
Fuzzified scoring of the functional assessment instrument
