Decadal mass balance of the Antarctic ice sheet from satellite radar altimetry and its contribution to global sea level change
(University of Missouri--Columbia, 2006)
period of 1992 - 2003. Several techniques are developed to improve the processing and analysis of both low and high resolution elevation change time series. Our research results show that the majority of the East Antarctica interior regions are thickening...
Source localization using TDOA with erroneous receiver positions
(University of Missouri--Columbia, 2005)
the source signal arrives at multiple spatially separated sensors. There are several methods to solve the TDOA source location problem, and two of the widely known methods are the Maximum Likelihood method and the Taylor-series method. Those methods assume...
Advances in automated surgery skills evaluation
(University of Missouri--Columbia, 2021)
. If the surgical activities that occur during a procedure are captured using a set of sensors, then the skill evaluation methodology can be defined as a motion and time series analysis problem. This work aims at developing machine learning approaches for automated...
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 ...
Scene matching between a quantitative map and a qualitative hand drawn sketch
(University of Missouri--Columbia, 2007)
comparison was made between the proposed approach and the Fuzzy Sequential Nearest Neighbor (FSNN) approach. Experiments were also run for cases where the sketches and the maps had unequal number of objects....
Land cover classification from satellite imagery, and its applications in cellular network planning
(University of Missouri--Columbia, 2005)
with the Landsat imagery. For multiple radar features, a higher accuracy improvement was found when combining the features (i.e., 13 x 13 Entropy, 9 x 9 data range, 19 x 19 mean) with the Landsat data. This study introduces an approach of fusing Landsat data...
Application of pulsed electric fields and magnetic pulse compressor technology in water disinfection
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pulsed electric field (PEF) is a promising technology for the non-thermal disinfection of water. Although research has already been conducted on the ...
Self-aligned microchip device for automated measurement of quantal exocytosis
(University of Missouri--Columbia, 2010)
Here we describe a method to fabricate a multi-channel high-throughput microchip device for measurement of quantal transmitter release from individual cells. Instead of bringing carbon-fiber electrodes to cells, the device ...
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 ...
General purpose evolutionary algorithm testbed
(University of Missouri--Columbia, 2009)
We developed a "General Purpose Evolutionary Algorithm Testbed" through which a wide variety of evolutionary algorithms can be implemented in hardware, quickly and with a little hardware knowledge. A user interface allows the user to enter...
A fast, 3 MV Marx generator for megavolt oil switch testing and integrated Abramyan network design
(University of Missouri--Columbia, 2005)
The University of Missouri-Columbia has a new test facility online to study oil breakdown of enhanced and uniform gaps. The 3 megavolt Marx generator is operational with switch configurations tested including large electrode ...
Simulation and experimental study of the multichanneling rimfire gas switch
(University of Missouri--Columbia, 2005)
Since 1985, the Rimfire switch has been used extensively in accelerators at Sandia National Laboratories. Demands for increased future accelerator performance require improvements to the Rimfire switch. This thesis is both ...
Automatic extraction of man-made objects from high-resolution satellite imagery by information fusion
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Recently available high-resolution commercial satellite imagery provides an important new data source for remote sensing applications. Automated feature ...
Linguistic summarization of human activity
(University of Missouri--Columbia, 2010)
summarize the state of the human at each moment, i.e. image, using features extracted from voxel person. Subsequently, temporal linguistic summarizations are produced from the state membership time series. State summaries are used to infer activity, which...
Temporal decision making using unsupervised learning
(University of Missouri--Columbia, 2021)
and number of outlier data points. Incremental internal Validity Indices (iCVIs) are used to monitor the performance of an on-line clustering algorithm. We study the internal incremental Davies-Bouldin (DB), Xie-Beni (XB), and Dunn internal cluster validity...
A MEMS based Coulter counter for cell sizing
(University of Missouri--Columbia, 2007)
(101 compared to 105 cells per experiment), an extremely short time frame from the exposure to reactant media to the initial measurement, serial time series measurements of a single cell, and optical microscopic monitoring of the experiment. Finally...
Low loss film bulk acoustic resonator in liquid environments
(University of Missouri--Columbia, 2008)
gap as an acoustic energy loss isolation layer of the FBAR in the aqueous media. The sensor was characterized and the Q factor was measured to be about 153 in the air and 140 in the water. An only 9% of Q reduction in the water was observed...
Simulation of solar photovoltaic power station
