Grafting Maple with Cedar
(University of Waterloo, 2023-01-26)Canada’s metaphor for integrating immigrants is the mosaic —vividly colored pieces of ethnicity, culture, racial identity, and language planted side by side, and in contrast to the melting pot of the American states, ... -
Study on Solution-Processable Polypyrrole-Based Conducting Polymers
(University of Waterloo, 2023-01-26)Due to the adjustable conductivity, cost-effective synthesis, and easy device fabrication, conducting polymers have wide-ranging applications in numerous areas, including sensors, solar cells, supercapacitors, and electrodes. ... -
Virtual Model Building for Multi-Axis Machine Tools Using Field Data
(University of Waterloo, 2023-01-26)Accurate machine dynamic models are the foundation of many advanced machining technologies such as virtual process planning and machine condition monitoring. Viewing recent designs of modern high-performance machine tools, ... -
Structure-Property correlation in additive manufactured Ti-5553 components
(University of Waterloo, 2023-01-26)A recently developed metastable β-titanium alloy, Ti-5Al-5V-5Mo-3Cr (Ti-5553), is a potential replacement to existing aircraft landing gear materials, offering a wider processing window along with excellent heat treatability. ... -
Stability of compressible boundary layers in presence of smooth roughness and wall temperature effects
(University of Waterloo, 2023-01-26)In natural laminar flow design, aircraft manufacturers aim to delay the laminar-to-turbulent transition by modifying the geometric features of the aircraft to stabilize the boundary layer. Yet, the transitional process is ... -
FlaKat: A Machine Learning-Based Categorization Framework for Flaky Tests
(University of Waterloo, 2023-01-26)Flaky tests can pass or fail non-deterministically, without alterations to a software system. Such tests are frequently encountered by developers and hinder the credibility of test suites. Thus, flaky tests have caught the ... -
Kampung Resilience: Mitigating threats of eviction in Kampung Muara Baru
(University of Waterloo, 2023-01-25)The following research investigates the National Capital Integrated Coastal Development (NCICD) master plan within the context of Muara Baru, Jakarta, as a neo-colonial practice that threatens to displace marginalized urban ... -
Scaling Permissioned Blockchains via Sharding
(University of Waterloo, 2023-01-25)Traditional distributed systems, such as those used in banking and real estate, require a trusted third party to operate and maintain them, which is highly dependent on the reliability of the operator. Since Bitcoin was ... -
Secure Computation and Proportionally Fair Collaboration in Federated Learning of Histopathology Images
(University of Waterloo, 2023-01-24)The prediction power of deep learning models depends on the size and quality of the training data. Having access to large-scale datasets enables the model to more precisely estimate the underlying distribution of the data. ... -
Extracting ECG-based cardiac information from the upper arm
(University of Waterloo, 2023-01-24)Cardiovascular disease (CVD) is the global number one cause of death. Therefore, there is an acute need for constantly monitoring cardiac conditions and/or cardiac monitoring for extended periods. The current clinical ... -
