Accessible Integration of Physiological Adaptation in Human-Robot Interaction
(University of Waterloo, 2021-09-21)Technological advancements in creating and commercializing novel unobtrusive wearable physiological sensors have generated new opportunities to develop adaptive human-robot interaction (HRI). Detecting complex human states ... -
Developments Towards Chromophore-Selectivity in Photoacoustic Remote Sensing Microscopy
(University of Waterloo, 2022-04-28)Medical imaging serves to diagnose and monitor illnesses in clinical settings. Several modalities such as X-Ray and Ultrasound have become ubiquitous due to their high utility. Photoacoustic microscopy, based on the ... -
An Intelligent System for Induction Motor Health Condition Monitoring
(University of Waterloo, 2015-04-08)Induction motors (IMs) are commonly used in both industrial applications and household appliances. An IM online condition monitoring system is very useful to identify the IM fault at its initial stage, in order to prevent ... -
Non-Invasive Blood Glucose Monitoring Using Electromagnetic Sensors
(University of Waterloo, 2022-05-16)Monitoring glycemia levels in people with diabetes has developed rapidly over the last decade. A broad range of easy-to-use systems of reliable accuracies are now deployed in the market following the introduction of the ... -
Open-Loop Transient Atomic Force Microscopy
(University of Waterloo, 2023-02-01)The Atomic Force Microscope (AFM) is an instrument for measuring, in fact “seeing”, phenomena at nanoscale (10^(-9) m) and all the way down to the atomic scale (<10^(-10) m). It was borne out of a need to observe physical ... -
Real-Time FPGA-Based Testbed for Evaluating Digital Predistortion in Fully Digital MIMO Transmitters
(University of Waterloo, 2023-04-27)As one of the key enabling technologies of 5G networks, massive multiple-input, multiple-output (MIMO) transmitters use many transmit chains to ensure a very high data rate and acceptable signal quality. Realizing Massive ... -
A Sparse Random Feature Model for Signal Decomposition
(University of Waterloo, 2022-05-11)Signal decomposition and multiscale signal analysis provide useful tools for time-frequency analysis. In this thesis, an overview of the signal decomposition problem is given and popular methods are discussed. A novel ... -
Speckle Noise Reduction via Homomorphic Elliptical Threshold Rotations in the Complex Wavelet Domain
(University of Waterloo, 2005)Many clinicians regard speckle noise as an undesirable artifact in ultrasound images masking the underlying pathology within a patient. Speckle noise is a random interference pattern formed by coherent radiation in a ... -
Unsupervised Methods for Condition-Based Maintenance in Non-Stationary Operating Conditions
(University of Waterloo, 2022-04-28)Maintenance and operation of modern dynamic engineering systems requires the use of robust maintenance strategies that are reliable under uncertainty. One such strategy is condition-based maintenance (CBM), in which ...
