Clustering in relational data and ontologies
(University of Missouri--Columbia, 2010)
This dissertation studies the problem of clustering objects represented by relational data. This is a pertinent problem as many real-world data sets can only be represented by relational data for which object-based clustering ...
Efficient H.264 video coding with a working memory of objects
(University of Missouri--Columbia, 2009)
, compresses the video streams which are then transmitted to a remote end for information analysis or archived in a storage device. In these types of video monitoring and surveillance scenarios, the video frame rate is often set relatively low...
Robust receiver design for RF communication and underwater acoustic communication
(University of Missouri--Columbia, 2010)
This dissertation includes two parts: robust receiver design for wireless radio frequency(RF) communication, and robust receiver design for underwater acoustic (UWA) communication. The methodology of study for the first ...
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 ...
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 ...
On the simulations of correlated nakagami-m fading channels using sum-of-sinusoids method
(University of Missouri--Columbia, 2006)
This research work discusses the generation of Nakagami-m fading samples from sum-of-sinusoids method in which Nakagami process is generated by taking square root of Gamma process. Gamma process itself can be realized using ...
Adaptive temporal difference learning of spatial memory in the water maze task
(University of Missouri--Columbia, 2009)
The goal of this work was to evaluate the performance of a biologically inspired Temporal Difference (TD) approach to the learning of spatial memory for a robot in a dry version of the Morris water maze task. The Morris ...
Fall detection using sound sensors
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] More than 1/3 of adults aged 65 and older fall each year in the US. The fall causes injures or serious health problems which have the related medical ...
A high voltage piezoelectric transformer for active interrogation
(University of Missouri--Columbia, 2009)
A resonant piezoelectric transformer circuit was developed for high voltage generation. The goal of this project was to produce 100 kV with a reasonably sized piezoelectric crystal. Several mechanisms leading to less than ...
