The Atmospheric Imaging Radar for High Resolution Observations of Severe Weather
(2012)
Mobile weather radars often utilize rapid scan strategies when collecting obser- vations of severe weather. Various techniques have been used to improve volume update times, including the use of agile and multi-beam radars. ...
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 ...
Robust Optical Wireless Links over Turbulent Media using Diversity Solutions
(2011)
Free-space optic (FSO) technology, i.e., optical wireless communication (OWC), is widely recognized as superior to radio frequency (RF) in many aspects. Visible and invisible optical wireless links solve first/last mile ...
QUANTUM SECURE COMMUNICATION USING POLARIZATION HOPPING MULTI-STAGE PROTOCOLS
(2016)
This dissertation presents a study of the security and performance of a quantum communication system using multi-stage multi-photon tolerant protocols. Multi-stage protocols are a generalization of the three-stage protocol ...
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 ...
EEG OSCILLATORY ACTIVITIES FROM HUMAN MOTOR BRAIN
(2015-12)
Motor skills are essential in people’s daily life in exploring and interacting with
the ambient environment. Impairments to motor functions affect the acquisition of
motor skills, which not only reduce the quality of ...
Extended Observation Particle Filter with SVD Template Generation Implemented for GPU
(2018-12)
This work presents a novel template updating strategy based on singular value decomposition (SVD) together with an expansion and extension of previous work combining observations across temporally adjacent frames to implement ...
Distributed Computation and Optimization over Networks
(2011)
This dissertation is devoted to the development of efficient, robust, and scalable distributed algorithms, which enable agents in a large-scale, multi-hop network to cooperatively compute a global quantity, or solve an ...
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 ...
