Kalman filtering beyond Gaussian innovation processes
(2022-12)
Estimating time-varying signals becomes particularly challenging under non Gaussian innovation processes such as sparse and rapidly time-varying noise dynamics. In this thesis, by building upon the recent progress in the ...
Six-port reflectometer based vector network analyzer with two independent RF power sources
(2022-01-28)
This thesis presents a novel use of a six-port reflectometer (SPR) to build an SPR based network analyzer (SPNA) operating with two independent radio frequency (RF) power sources. The SPNA was first introduced by Hoer and ...
Improving power system voltage regulation: a capacitive ladder-based power electronic AC voltage regulator
(2022-10-13)
This thesis proposes a new circuit topology for a capacitive ladder-based electronic voltage regulator (CL-EVR) which is a substitute for an electromechanical tap changer in power transformers. The proposed CL-EVR employs ...
Inverse design of Huygens’ metasurfaces for 2D and 3D power pattern synthesis
(2022-09-06)
Electromagnetic (EM) metasurfaces are quasi two-dimensional structures that consist of artificial “atoms”, typically referred to as meta-atoms. These meta-atoms, also known as unit cells, are small compared to the operational ...
Low-latency airborne collision detection and avoidance system for unmanned aircraft systems in a varying environment
(2022-08-22)
Detect-and-avoid (DAA) systems equipped with non-cooperative sensors for unmanned aircraft systems (UAS) beyond visual line-of-sight (BVLOS) operation is of interest to many researchers and industries today. Planning ...
Arbitrary mode-n convolution of physical tensors with applications in optics
(2022-08-23)
Multidimension functions frequently appear in Fourier Optics. For example, in a polychromatic optical system, one could have three spatial dimensions for space, one dimension for time, and one dimension for wavelength. ...
Classifying SARS-CoV-2 and common respiratory viruses from genome assemblies
(2022-12-13)
Polymerase chain reaction (PCR) testing has widespread use in the systematic identification of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) strains. However, another approach for identifying the SARS-CoV-2 ...
Signal parameter estimation of damped sinusoidal waveforms using deep learning
(2022-12-21)
Sinusoids and damped signals are a fundamental part of different engineering fields. Analysis of these signals to give an accurate estimation of certain parameters such as frequency, damping factor, and phase angle is ...
Design and implementation of a thermal hardware-in-the-loop (THIL) platform for evaluating physical cooling systems in real-time simulation
(2022-12-27)
Power electronics (PE) take a critical role in electricity transformation, transmission and application in modern industrial utilization. Improving the efficiency while maintaining the stability of performance of electrical ...
Lens-type redirective reconfigurable intelligent surfaces for multi-user MIMO communications
(2022-12-23)
Reconfigurable intelligent surfaces (RIS), also known as smart repeaters, have been
widely adopted in the open literature as a low-cost, energy-efficient solution to tackle the blockage problem in existing wireless networks. ...
