Design and testing of helical antennas for a RF test facility
(University of Missouri--Columbia, 2012)
RF facilities are necessary to accurately and systematically test multiple types of electronic devices in an electromagnetically quiet environment. Typical RF facilities consist of an anechoic chamber, a room that shields ...
Robot methods for human-robot spatial language interaction
(University of Missouri--Columbia, 2013)
This thesis talks about a work to design a robot with some to interact with human by spatial language. The robot is a differential drive robot with Kinect camera. The thesis proposes the perception methods which include ...
Projectile vibration analysis of an electromagnetic launcher
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A novel method for the calibration of accelerometers using an electromagnetic launcher (EML) has been investigated by the University of Missouri. The ...
Searching objects of interest in large scale data
(University of Missouri--Columbia, 2012)
The research on object detection/tracking and large scale visual search/recognition has recently gained substantial progress and has started to contribute to improving the quality of life worldwide: real-time face detectors ...
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. ...
Design of an Efficient Controller for Arterial Oxygen Saturation in Neonatal Infants
(University of Missouri--Columbia, 2013)
A main problems for premature infants is respiratory distress syndrome (IRDS), also called neonatal respiratory distress syndrome, or respiratory distress syndrome of newborn. Due to IRDS, the infant requires intervention ...
Characterization of ion sources for compact accelerator neutron production
(University of Missouri--Columbia, 2011)
Compact neutron interrogation systems are a good candidate for use in active interrogation systems when large scale active or passive interrogation systems are not ideal. Field emitter arrays and plasma ion sources could ...
Investigation and optimization of a high voltage piezoelectric particle accelerator
(University of Missouri--Columbia, 2012)
This thesis contains analysis of the piezoelectric effect as a means to produce high voltage. The goal of this analysis is to determine if piezoelectric transformers can be used effectively in compact x-ray source applications. ...
Ground based interferometric radar initial look at Longview, Blue Springs, Tuttle Creek, and Milford Dams
(University of Missouri--Columbia, 2012)
Measuring millimeter and smaller deformation has been demonstrated in the literature using RADAR. To address in part the limitations in current commercial satellite-based SAR datasets, a University of Missouri (MU) team ...
GBIR crosstalk reduction of fully polarimetric data from Blue Springs Dam
(University of Missouri--Columbia, 2012)
An investigation into reducing crosstalk from Blue Springs Dam GBIR fully polarimetric data was conducted. Advanced polarimetric processing and techniques often rely on precise phase measurement. One benefit of crosstalk ...
Automatic detection of explosive devices in infrared imagery using texture with adaptive background mixture models
(University of Missouri--Columbia, 2011)
Infrared cameras can be used to image unpaved roads containing buried explosive hazards where detection relies upon differences between settled and disturbed soil in addition to thermal emissivity. Used is a variation of ...
Motion analysis for in-home gait and balance assessment using inexpensive video sensors
(University of Missouri--Columbia, 2011)
Clinical research has identified a clear link between human gait characteristics and different medical conditions. We are particularly interested in gait and balance analysis for fall risk assessment in elderly people. ...
Plasma and Monte Carlo modeling of a psuedospark x-ray source
(University of Missouri--Columbia, 2011)
A pseudospark x-ray source, for application in portable medical imaging, has been simulated at the University of Missouri. This device would allow for deployment in many venues such as emergency rooms, doctors' offices, ...
Implementation of finite impulse response (FIR) filter as test application on general purpose evolutionary algorithm testbed system
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A 19th order Finite Impulse Response (FIR) filter is implemented as a test application for Gpeat, a general purpose evolutionary algorithm testbed. ...
Characterizing carrier transport in silicon thin film metal semiconductor metal structures
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Due to its operational simplicity and ease of fabrication, metal semiconductor metal thin film structures have been the focus of attention for many ...
Object detection with large intra-class variation
(University of Missouri--Columbia, 2011)
For object detection, the state-of-the-art performance is achieved through supervised learning. The performances of object detectors of this kind are mainly determined by two factors: features and underlying classification ...
Source localization in the presence of sensor manifold uncertainties and synchronization error
(University of Missouri--Columbia, 2011)
Passive source localization is a commonly used technology which can be applied to many areas. A lot of positioning methods have been derived on this subject, such as time of arrivals (TOAs), time differences of arrival ...
Exploring passive heartbeat detection using a hydraulic bed sensor system
(University of Missouri--Columbia, 2011)
Sleep monitoring of heartbeat, respiration and restlessness can help to detect sleep disturbances which may be indicative of poor health and functional deficits, especially in older adults. This work investigates a new ...
