Efficient H.264 video coding with a working memory of objects
(University of Missouri--Columbia, 2009)
Efficient spatiotemporal prediction to remove the source redundancy is critical in video coding. The newest international standard H.264 video coding introduces several advanced features, such as multiple-frame motion ...
Influence of gamma irradiation on chemical vapor deposited boron-doped diamond films
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Carbon based materials such as graphite, fullerene, amorphous carbon and diamond in all forms and specifically doped diamond is of great interest owing ...
Simulation algorithms for fractal radiation
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis presents a method to analyze a series of structures, referred to as fractals, that radiate electromagnetic waves. The fractal series are ...
Atmospheric effects on near-infrared free space optical communication links
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] High-bandwidth optical communication systems are increasingly in demand. As radio frequency (RF) telecommunications approach its natural limit in ...
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 ...
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 ...
Computational modeling of the fear circuit : a system approach to understand anxiety and stress disorder
(University of Missouri--Columbia, 2009)
Computational models are becoming increasingly important to systems neuroscience. In fear learning, although there have been a few attempts at modeling emotional learning and memory in the past, most were limited to ...
MizzouSMP
(University of Missouri--Columbia, 2009)
This paper covers the implementation of a 32 Bit RISC multiprocessor MizzouSMP. It was developed from MizzouRisc, simulated on Aldec Active HDL, implemented on a Altera DE2 board. The MizzouSMP core can be configured to ...
Type-1 and type-2 fuzzy systems for detecting visitors in an uncertain environment
(University of Missouri--Columbia, 2009)
In this work, I have developed an algorithm to detect the presence of visitors in a noninvasive manner. This algorithm is designed as part of an in home monitoring system. The data from the algorithm will be used as a way ...
Fabrication and characterization of polymer based metal-oxide-semiconductor and non-volatile memory devices
(University of Missouri--Columbia, 2009)
Organic field-effect transistors (FETs) have been widely investigated due to their potential applications in low cost, large area, and flexible electronics. Despite the rapid progress in organic FETs there are still obstacles ...
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 ...
Computational neural models at molecular, cellular and behavioral levels : three case studies
(University of Missouri--Columbia, 2009)
Biological findings from molecular, cellular and behavior levels can be difficult to understand functions. Computational tools and systems concepts facilitate integration of information across levels to further understanding ...
Adaptive array signal processing using the concentric ring array and the spherical array
(University of Missouri--Columbia, 2009)
This thesis introduces new methods for partial adaptive beamforming using concentric ring and spherical arrays for acoustic signals on a partially known interference environment. We propose novel methods to choose intra-ring ...
Fall detection using acoustic features and one class classifiers
(University of Missouri--Columbia, 2009)
With the increasing of elderly population, there are more and more health problems occurring in everyday activities among this group of people. An investigation shows many elderly people get injures or trigger more serious ...
Cellular neural network virtual machine for graphics hardware with applications in image processing
(University of Missouri--Columbia, 2009)
The inherent massive parallelism of cellular neural networks makes them an ideal computational platform for kernel-based algorithms and image processing. General-purpose GPUs provide similar massive parallelism, but it can ...
