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 ... -
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 ... -
Comparison of substrate conditions in low-temperature gallium arsenide and semi-insulating gallium arsenide during terahertz pulse generation
(University of Missouri--Columbia, 2011)The use of GaAs photoconductive semiconductor switches (PCSS) for generating THz radiation is well known. Both semi-insulating (SI) and Low-temperature (LT) grown Gallium Arsenide (GaAs) have been used. In this research ... -
Design and simulation of a compact radiating system for high power microwaves in the 4 to 6 GHz range
(University of Missouri--Columbia, 2011)As high power microwave technologies have advanced, demands have called for sources and radiators to become more compact. The University of Missouri has designed and simulated a compact radiating system for a compact virtual ... -
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 ... -
Maximizing terahertz pulse amplitude from low temperature gallium arsenide photo conductive semiconductor switch
(University of Missouri--Columbia, 2011)A signal is produced by the photoconductive action in a PCSS, which travels through the bulk to the metallic contacts and is radiated through the electrodes of the PCSS. The simulation analysis was done for the semiconductor ... -
MEMS biosensor for detection of Escherichia coli O157:H7 in food products
(University of Missouri--Columbia, 2011)Escherichia coli O157:H7, is one of the most common pathogens that has caused several outbreaks in recent years. In 2010-11 there were 5 outbreaks of E.coli and thousands were victim of it. Thus there is an immediate need ... -
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 ... -
Optimizing antenna gain with a metamaterial filter
(University of Missouri--Columbia, 2011)Metamaterials are man-made structures, usually designed by placing electromagnetic resonators, such as split ring resonators (SRRs), in a periodic array. Metamaterials also exhibit lensing properties, and, when placed next ... -
Pattern recognition of mixed signals using guided under-determined source signal separation
(University of Missouri--Columbia, 2011)In typical problems involving pattern recognition, the challenge lies in selecting a good set of features and in devising a reliable algorithm to recognize any particular vector of such features. In general, even when noise ... -
Planar detection using modified expectation maximization
(University of Missouri--Columbia, 2011)In this work the task of planar detection in an image pair is cast as an incomplete data problem where the parameters to be estimated are the ones that define the homographies induced by the planar regions in the scene. ... -
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, ... -
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 ... -
Visual recognition using hybrid camera
(University of Missouri--Columbia, 2011)Visual recognition is an exciting but difficult task. Recent dramatic advance in compute vision technology has made some promising progress. For example, the launch of hybrid camera provides both RGB and depth information ...
