Fingerprint-based indoor positioning and intensity classification using an improved machine learning framework
(University of Waterloo, 2021-10-21)Covid-19 has changed the world in terms of business, public, and many other fields. Millions of livelihoods have been affected by the pandemic. Amidst the upheaval, work from home and restrictions on indoor gatherings have ... -
Finite Element Analysis of Multi-Material Die-Cast Tooling by Additive Manufacturing
(University of Waterloo, 2024-05-10)The predominant challenge encountered in the high-pressure die casting of aluminum is the deterioration of casting dies because of thermal fatigue or heat checking. This issue largely stems from the inadequate thermal ... -
Finite Element Methods to Analyze Helical Stent Expansion
(University of Waterloo, 2014-07-18)Stent angioplasty or stenting is the standard noninvasive therapy method to address narrowing of the arteries and restore blood flow. Although drug-eluting stents have resolved immediate restenosis (i.e., re-narrowing of ... -
Finite Strain Elastoplasticity: Consistent Eulerian and Lagrangian Approaches
(University of Waterloo, 2009-05-08)Infinitesimal strain approximation and its additive decomposition into elastic and plastic parts used in phenomenological plasticity models are incapable of predicting the hardening behavior of materials for large strain ... -
