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 ...
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 ...
Development of urban area geospatial information products from high resolution satellite imagery using advanced image analysis techniques
(University of Missouri--Columbia, 2004)
The latest generation of commercial satellite imaging sensors have a number of characteristics (e.g. high spatial resolution, multispectral bands, and quick revisit time), that make them ideal data sources for a variety ...
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 ...
Shallow trench isolation process in microfabrication for flash (NAND) memory
(University of Missouri--Columbia, 2008)
Technology is steadily advancing where semiconductors and microelectronics have become such a huge source of revenue and area of technological interest, resulting in reduced device geometries and more complicated microelectronic ...
Data-driven methods for analyzing ballistocardiograms in longitudinal cardiovascular monitoring
(University of Missouri--Columbia, 2019)
Cardiovascular disease (CVD) is the leading cause of death in the US; about 48% of American adults have one or more types of CVD. The importance of continuous monitoring of the older population, for early detection of ...
Case study of normal and high glucose laden cell response to cellular phone radiation using GTEM cell
(University of Missouri--Columbia, 2012)
The primary objective of this dissertation is twofold. First, to study the response of red and white blood cell and normal and high glucose blood to cellular phone radiation exposures at frequencies of 850 and 900 MHz. ...
The development of electrohydraulic steering control system for off-road vehicle automatic guidance
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The researches in this thesis focus on the development of computer controlled electrohydraulic steering control system for off-road vehicle automatic ...
Synthesis and characterization of TiO2 nanotube Schottky diodes
(University of Missouri--Columbia, 2021)
Metal-semiconductor interfaces on one-dimensional (1D) nanostructures represent crucial building blocks for next-generation nanoelectronics. Over the past two decades, chemically synthesized titanium dioxide nanotubes ...
Fall detection using sound sensors
(University of Missouri--Columbia, 2009)
many falls are not reported, this may be an indication of increasing frailty. To address the above problem we propose to develop fall detection system (FADE) that will automatically report a fall to the monitoring caregiver. As opposed to many existing...
Unpaved road detection using optimized log Gabor filter banks
(University of Missouri--Columbia, 2021)
The revised unpaved road detection system (RURD) is a novel method for detecting unpaved roads in an arid environment from color imagery collected by a forward-looking camera mounted on a moving platform. The objective is ...
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 ...
Advances in transfer learning methods based on computational intelligence
(University of Missouri--Columbia, 2020)
was manually evaluated using nursing visit reports from a homegrown electronic medical record (EMR) system. In this work, the transfer learning SVM approach outperformed three other methods, i.e., regular SVM, one-class SVM, and one-class kNN....
Chronomorphic characterization and radiolytic degradation analysis of polyurethane with monte carlo modeling of the neutron spectra surrounding age pettrace cyclotron
(University of Missouri--Columbia, 2018)
This thesis describes the development of fast neutron irradiation positions at the MURR GE PETtrace cyclotron for polyurethane (PUR) radiolysis studies. Monte Carlo N-Particle (MCNP) Transport code was used to calculate ...
Non-invasive monitoring of vital signs using recliner chair and respiratory pattern analysis
(University of Missouri--Columbia, 2018)
In-home monitoring has the potential to help track health changes for older adults with chronic health conditions, thereby making early treatment possible when exacerbations arise. A recliner chair is often used by older ...
Advanced nanodielectric material development and scaling for use in compact ultra-high voltage capacitor prototypes
(University of Missouri--Columbia, 2019)
The dielectric material employed in this effort is a proprietary nanocomposite material, MU100. The material was initially developed to shrink high frequency, high voltage, dielectric loaded antennas; however, due to its ...
Development of a dual frequency, folded topology, dielectric waveguide lens antenna
(University of Missouri--Columbia, 2018)
There is an emerging need for antennas capable of operating in the field of high power microwaves (HPMs) especially those which exhibit high gain, wide bandwidth, and steering. Conventional high gain antennas are often ...
Tracing of internal layers in radar echograms from a Greenland study region
(University of Missouri--Columbia, 2006)
Signs of long-term glaciological processes and past ice sheet structure are preserved in the internal layer signatures of the Greenland ice sheet. Internal layer data have been collected over a considerable portion of the ...
A novel approach for treating resistant hypertension using a controlled-pump accumulator relief device
