Advances in Synthetic Aperture Radar from a Wavenumber Perspective
(2017-12-15)
This dissertation examines the wavenumber domain of Synthetic Aperture Radar (SAR) images. This domain is the inverse Fourier transform domain of a SAR image. The dissertation begins with the radar receiver's signal model ...
Distributed Computation of Graph Spectrum, Eigenvector Centrality, and Solution to Linear Equations
(2017-12-15)
This dissertation is devoted to the development of distributed algorithms, with which nodes in a large decentralized network can accomplish tasks that are seemingly difficult without an omniscient central node. The tasks ...
Real-Time Narrowband and Wideband Beamforming Techniques for Fully-Digital RF Arrays
(2017-12)
Elemental digital beamforming offers increased flexibility for multi-function radio frequency (RF) systems supporting radar and communications applications. As fully digital arrays, components, and subsystems are becoming ...
RF Modeling and Electromagnetic Analysis of Implantable Devices in Magnetic Resonance Imaging
(2017-12)
Magnetic Resonance Imaging (MRI) has become a generally accepted medical procedure and it is estimated that all the U.S. population will have at least one MRI scan in their lifetime. Unlike common radiography and computed ...
HIGH-THROUGHPUT FLUORESCENCE MICROSCOPY FOR AUTOMATED CLINICAL APPLICATIONS
(2017-05-12)
Fluorescence in situ hybridization (FISH) is a powerful tool for visualizing and detecting genetic abnormalities. Manual scoring FISH analysis is a tedious and labor-and-time-consuming task. Automated image acquisition and ...
Digital Signal Processor Based Real-Time Phased Array Radar Backend System and Optimization Algorithms
(2017-12)
This dissertation presents an implementation of multifunctional large-scale phased array radar based on the scalable DSP platform.
The challenge of building large-scale phased array radar backend is how to address the ...
New Implication of Short Circuit Analysis in Assessing Impact of Renewable Energy Resources on System Strength of a Power Grid
(2017-08-01)
The increasing penetration of renewable resources raised a new challenge in power system planning and operation to maintain system reliability. Several serious operational issues may take place when significant amount of ...
On the Potential of Adaptive Beamforming for Phased-Array Weather Radar
(2017-05-12)
As the Weather Surveillance Radar 1988 Doppler network reaches the end of its expected life, a network of multifunction phased-array radars (MPAR) supporting both aircraft and weather surveillance missions has been proposed. ...
Advanced Aviation Weather Radar Data Processing and Real-Time Implementations
(2017-12)
The objectives of this dissertation work are developing an enhanced intelligent radar signal and data processing framework for aviation hazard detection, classification and monitoring, and real-time implementation on massive ...
DEEP LEARNING APPROACHES IN PROBLEMS IN VARIOUS-DIMENSIONAL DATA
(2017)
This thesis develop efficient deep learning based methods for a series of tasks. I believe these problems to be inherently worth developing because of their connections to problems of practical importance. In particular, ...
