Robust motion estimation techniques
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Motion estimation is a very important step in many video processing tasks, including video compression, object tracking, and etc. A video may experience ...
Photoswitch-based Class E microwave power amplifer
(University of Missouri--Columbia, 2007)
Currently radar systems have problems with power losses and efficiency, so more power is used and more heat removal is needed. The primary source of loss is the final amplifier in the transmission-receive (TR) module. The ...
Computational modeling of sensory circuitry in the nucleus tractus solitarii from arterial baroreceptor and somatosensory inputs
(University of Missouri--Columbia, 2007)
Baroreflex function regulates the arterial blood pressure in our body. The baroreflex is considered to be an integrated negative feedback system. NTS (Nucleus tractus solitarius) is one of key subsystems in this baroreflex ...
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 ...
Advanced feature based techniques for landmine detection using ground penetrating radar
(University of Missouri--Columbia, 2007)
Land mine detection is an important and yet challenging problem that remains to be solved. It is not only a problem for military, but also for humanitarian concern. The goal of this research is to propose some techniques ...
