[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this thesis work, an ultra-wideband signal generator circuitry is presented for the Ultra-wideband Short-range Radar Human ID System. Investigation is carried out towards...
Thrust measurements of a ferroelectric plasma source [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Ferroelectric thrusters can be used in applications where small thrusts are useful such as guiding the movement of satellites. The Pulsed Power and Plasma Science group in the Electrical and Computer Engineering department at MU is characterizing a...
Alternative materials for radiovoltaics
(University of Missouri--Columbia, 2017)
radiation-resistance in the liquid phase. With liquid selenium established as a promising material for radiovoltaics, this work also presents a neutron diffraction study on the material's atomic structure, which has been the subject of dispute in published...
Hyperspectral unmixing and band weighting for multiple endmember sets
(University of Missouri--Columbia, 2014)
of endmembers, estimates proportion values, and assigns partition specic band weights. Band weights are estimated using weight decay and sparsity promoting techniques. The proposed approach is compared with state of the art method present in the literature...
Nonlinear electroelastic resonators /
(University of Missouri--Columbia, 2016)
in new ways. In the first chapter linear piezoelectric device physics is reviewed and a method for improving the quality factor of mass sensors in a liquid environment is presented. However, the limitations of this preliminary work motivate the focus...
Efficient estimators in closed-form for source localization and sensor network self-localization
(University of Missouri--Columbia, 2011)
estimates of unknown sensor nodes in a sensor network where anchor nodes, whose positions are known accurately, are present or absent. We also study sensor refinement by deploying new unknown nodes. The inter-node measurement considered is time of arrivals...
Landmine classification using possibilistic K-nearest neighbors with wideband electromagnetic induction data
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this thesis, a possibilistic K-nearest neighbor classifier is presented to distinguish between and classify mine and non-mine targets on data obtained from wideband...
Fabrication and characterization of micro-chip based shockwave generator for particle delivery and cell transfection
(University of Missouri--Columbia, 2014)
compositions by adding polymers or other nanoscale energetic materials. Also, these nanothermites can be integrated with MEMS based systems owing to their low critical combustion diameters and high energy densities. The present research describes...
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 is present in the feature...
Simultaneous electrophoretic deposition of copper oxide/aluminum nanothermite films
(University of Missouri--Columbia, 2012)
as cracking and delamination of the CuO/Al nanorod films was not present....
Accounting for spectral variability in hyperspectral unmixing using beta endmember distributions
(University of Missouri--Columbia, 2013)
Hyperspectral imaging is widely used in the field of remote sensing (Goetz, et al., 1985; Green, et al., 1998). In a hyperspectral imaging system, sensors collect radiance/reflectance values over an area (or a scene) across ...
An efficient closed-form solution for wideband source direction-of-arrival estimation
