Channel modeling, estimation and equalization in wireless communication
(University of Missouri--Columbia, 2005)
Channel modeling, estimation and equalization are discussed throughout this dissertation. Relevant research topics are first studied at the beginning of each chapter and the new methods are proposed to improve the system ...
A temporal analysis system for early detection of health changes
(University of Missouri--Columbia, 2014)
To make it possible for elders to live independently at home and yet get help from health care providers when small changes in health conditions take place, smart home technologies are developed to enhance safety and monitor ...
Deposition and characterization of high permittivity thin-film dielectrics
(University of Missouri--Columbia, 2006)
As integrated circuit (IC) devices scale to ever smaller nodes, replacing the front end dielectric has become a primary challenge. To enable greater device densities, control power consumption, and enhance performance, a ...
Distributed resource allocation and performance optimization for video communication over mesh networks based on swarm intelligence
(University of Missouri--Columbia, 2007)
Mesh networking technologies allow a system of communication devices to communicate with each other over a dynamic and self-organizing wired or wireless network from everywhere at anytime. Large-scale mesh communication ...
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 ...
Optimization of charge collection efficiency in MSM photodetector
(University of Missouri--Columbia, 2005)
The effects of different geometries, heights and concentrations per unit area of gratings in the active region of a metal semiconductor metal photo-detector have been analyzed for enhanced charge collection through ...
Developing neural network applications using LabVIEW
(University of Missouri--Columbia, 2005)
Artificial Neural Networks (ANN) have gained tremendous popularity over the last few decades. They are considered as substitutes for classical techniques which have been followed for many years. Many neural network ...
Theoretical investigation of a laser triggered spark gap
(University of Missouri--Columbia, 2005)
A model of a spark gap used as a shorting switch in a Blumlein pulse power system has been developed. The model is separated into a pre-breakdown kinetic model and a post-breakdown fluid model. The kinetic model is used ...
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 ...
Charge collection mechanisms in a sub-micron grated MSM photodector: field analysis
(University of Missouri--Columbia, 2005)
Enhanced charge collection mechanisms due to sub-micron wall-like silicon structures on the active surface of a metal-semiconductor-metal (MSM) photodetector were studied through the analysis of transmitted electromagnetic ...
Investigation of the accuracy of Grover's method when solving for the mutual inductance of two single-layer coaxial coils
(University of Missouri--Columbia, 2005)
In 1933 Grover introduced a convenient method of calculating the mutual inductance between two single-layer coaxial coils that is still widely accepted as the standard today. He produced tables of numeric values from Clem's ...
Performance evaluation of a low cost processor with wireless connectivity
(University of Missouri--Columbia, 2005)
This study shows the development and analysis of the connectivity of a wireless system using a low cost processor. First, we designed a system with two sensor processors and a server PC. Second, we developed two protocols; ...
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 ...
Techniques for improving landmine detection using ground penetrating radar
(University of Missouri--Columbia, 2006)
Improving the probability of detection of landmines is a challenging task for many scientists all around the world. The goal of this research is to be a part of this challenging work to investigate techniques for ...
Fuse holder damage investigation
(University of Missouri--Columbia, 2006)
The explosion of fuse holders at a certain 161 kV: 34.5 kV Ameren UE substation in the Potosi area was investigated. The Alternative Transients Program -Electromagnetic Transients Program (ATP-EMTP) was used to model and ...
Mesoporous iron oxide energetic composites with slow burn rate, sustained pressure and reduced ESD sensitivity for propellant applications
(University of Missouri--Columbia, 2006)
The objective of this thesis is to synthesize a slow burning nanoenergetic formulation of mesoporous iron oxide with sustainable pressure characteristics and reduced electrostatic discharge ignition sensitivity. The choice ...
