The spatial cross-correlation coefficient as an ultrasonic detection statistic
(University of Missouri--Columbia, 2007)
-correlation coefficient as an additional detection statistic. The correlation coefficients are calculated between A-scans digitized at adjacent measurement positions and can be formed into images that are similar to C-scan images. We also describe an approach...
Automated building footprint extraction from high resolution LIDAR DEM imagery
(University of Missouri--Columbia, 2005)
Geographic Information Systems (GIS) are used in the fields of urban planning, environmental management, agriculture, transportation, utilities etc. because of their ability to provide geospatial information organized in ...
Mobile speed estimation for hierarchical wireless network
(University of Missouri--Columbia, 2005)
on the development of a mobile speed estimation algorithm for practical wireless information system. The statistical properties of different wireless propagation environments are analyzed based on their respective mathematical reference models. The analytical results...
Electromagnetic effects on soybeans
(University of Missouri--Columbia, 2007)
on Magellan for repeat experiments were inconclusive at best. Germination for case studies with two hundred samples showed marked improvement but the statistical significance for much larger sample (1000 seeds) decreased. All the experiments were conducted...
Transmission distortion modeling for wireless video communication
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A major challenge in video wireless communication is that the channel is time-varying and error-prone. The lost video packet and the packet received ...

This project deals with the analysis of high power radio frequency effects on a non-linear opposed contact GaAs photoconductive semiconductor switch, used in high power microwave generation. Specifically, effects of heating ...
Optimum receiver design and performance analysis for wireless communication
(University of Missouri--Columbia, 2005)
range of wireless communication systems under various practical system configurations. A statistical discrete-time system model is proposed for wireless communication systems, and it provides a generic analysis and simulation framework for the design...
Design and construction of helmholtz coil for biomagnetic studies on soybean
(University of Missouri--Columbia, 2008)
's geomagnetic fields. The extreme-low-frequency (ELF) AC magnetic field is more conducive to Soybean germination compared to the static magnetic field. An alternating magnetic field of 60 Hz was shown to have a statistically significant effect on soybean seed...
Development of a gigawatt repetitive pulse modulator and high-pressure switch test stand and results from high-pressure switch tests
(University of Missouri--Columbia, 2006)
The research described in this thesis documents the efforts in developing repetitively pulsed, high-pressure oil switch technology. A high-pressure oil switch has been designed and optimized for lifetime operation to more ...
Embedded system design and power-rate-distortion optimization for video encoding under energy constraints
(University of Missouri--Columbia, 2007)
videos with non-stationary statistics, using the proposed P-R-D optimization technology, the encoder energy consumption can be significantly reduced. This has many important applications in energy-efficient portable video communication system design....
Cognitive radios: spectrum sensing issues
(University of Missouri--Columbia, 2007)
Cognitive Radio can smartly sense and adapts with the changing environment by altering its transmitting parameters, such as modulation, frequency, frame format etc. The main challenges with cognitive radios are that it ...
Land cover classification from satellite imagery, and its applications in cellular network planning
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] To further increase the classification accuracies, radar image processing techniques were investigated to preprocess the Radarsat data before classification. ...
