Non-LTI Antenna Design and Modeling Techniques
(2022-05-13)
Nearly all contemporary antenna systems are Linear Time-Invariant (LTI) devices, and allow for assumptions of frequency independence and reciprocity, but are governed by strict bounds on their performance. Recently, nonlinear ...
Nonlinear Equalization and Digital Pre-Distortion Techniques for Future Radar and Communications Digital Array Systems
(2020-05-08)
Modern radar (military, automotive, weather, etc.) and communication systems seek to leverage the spatio-spectral efficiency of phased arrays. Specifically, there is an increasingly large demand for fully-digital arrays, ...
Robust Velocity Dealiasing for Weather Radar Based on Convolutional Neural Networks
(2023-05-12)
Doppler weather radar is an essential tool for monitoring and warning of hazardous weather phenomena. In weather radar, achieving a longer aliasing range (ra) is crucial for surveillance, and a higher aliasing velocity ...
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 ...
Study of advanced resonant photonic gratings in the mid-infrared spectrum for the chemical sensing applications
(2023-08-04)
This dissertation focuses on developing advanced Mid-IR optical devices for chip-scale chemical sensing. Various Mid-IR techniques based on Beer-Lambert’s law offer valuable insights into molecular interactions but suffer ...
Multilayered periodic reflector and Bragg waveguide for integrated optics.
(1980)
With computed data, comparison and discussion of some important characteristics such as reflectivity and selectivity of a double triple, quadruple and quintuple layered periodic reflector are extensively analyzed.
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 ...
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 ...
