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 ...
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 ...
DISTRIBUTED ESTIMATION OF CENTRALITY MEASURES IN COMPLEX NETWORKS
(2016-12-16)
Knowing how important a node or an edge is, within a network, can be very valuable, for instance, in identifying those who are susceptible to malicious attacks, those who are bottlenecks to network performances, and those ...
Application of Compressive Sensing to Weather Radars
(2016-12-16)
The capability and importance of weather radar are proven for hazardous weathers detection, monitoring, and prediction in both research and operations. Continuous efforts have been made in improving radar performance in ...
Digital Predistortion of Pseudo-Orthogonal Wideband Waveforms for Dual-Polarimetric Phased Array Radars
(2016-05)
Many new and interesting radar operational modes and techniques are being explored to maximize the efficiency and utility of next-generation radar systems while complying with increasingly stringent operational and budgeting ...
