Broadband beamforming and direction finding using concentric ring array
(University of Missouri--Columbia, 2005)
Sensor arrays have been used widely in applications including radar, sonar, seismology, biomedicine, communications and imaging. A very popular type of sensor array is circular array, which has almost invariant array pattern in azimuthal plane...
Single carrier frequency domain equalization for broadband wireless communications
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This thesis discusses different channel estimation techniques, channel equalization and various diversity schemes for broadband wireless communication employing single...
Land cover classification from satellite imagery, and its applications in cellular network planning
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] To further increase the classification accuracies, radar image processing techniques were investigated to preprocess the Radarsat data before classification. Eight processing...
Synthesis of ordered nanoenergetic composites
(University of Missouri--Columbia, 2005)
Energetic materials can be defined as the substances or mixtures that react chemically to release energy required for their intended application. Thermite is a subgroup of pyrotechnic, a class of energetic material. ...
A TEM cell design to study electromagnetic radiation exposure from cellular phones
(University of Missouri--Columbia, 2008)
A transverse electromagnetic (TEM) cell was designed and fitted with a double ended monopole antenna as a signal leader in order to couple electromagnetic radiation from GSM 900 and 1800 commercial cellular phones into a ...
Decadal mass balance of the Antarctic ice sheet from satellite radar altimetry and its contribution to global sea level change
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this research, we estimated the decadal mass balance of the Antarctic ice sheet using the European Space Agency's ERS-1 and ERS-2 satellite radar altimeter data over the time...
Anti-fog coatings using the super-hydrophobic approach
(University of Missouri--Columbia, 2008)
by increasing surface roughness. Superhydrophobic surfaces require both appropriate surface roughness and low surface energy materials and numerous methods to attain these requirements have been demonstrated. We have made extensive use of nano-particles to help...
Simulation and experimental study of the multichanneling rimfire gas switch
(University of Missouri--Columbia, 2005)
the University of Missouri Terawatt Test Stand, experiments were conducted studying the multichanneling cascade section of the switch. The electrical affects of multichanneling and a method to force multichanneling was presented. In addition, an objective curve...
Automatic extraction of man-made objects from high-resolution satellite imagery by information fusion
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Recently available high-resolution commercial satellite imagery provides an important new data source for remote sensing applications. Automated feature extraction (AFE...
Compact power conditioning and RF systems for a high power RF source
(University of Missouri--Columbia, 2008)
As part of the University Consortium for High Power Microwave (HPM) Integration, compact power conditioning and RF systems were investigated with a maximum diameter of 15.24 cm. A simulator of a flux compression generator (FCG) was built as a non...
Ex situ variable angle spectroscopic ellipsometry studies on chemical vapor deposited boron-doped diamond films : layered structure and modeling aspects
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Diamond possesses several outstanding physical properties (mechanical hardness, thermal conductivity, chemical inertness and high index of refraction) that may qualify...
Source localization using TDOA with erroneous receiver positions
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Source localization has been an active research for several years. It has applications in many areas such as geolocation and mobile user location. Various methodologies have been...
Optimum receiver design and performance analysis for wireless communication
(University of Missouri--Columbia, 2005)

High-speed, high-accuracy method for mutual inductance calculations
(University of Missouri--Columbia, 2008)
Three methods for calculating the mutual inductance of coils are examined and compared: a finite-element field code analysis method, theoretical analysis method, and F. W. Grover's tabular method. These methods are applied ...
