An asymmetric elastic-plastic analysis of the load-controlled rotating bending test and its application in the fatigue life estimation of wrought magnesium AZ31B
(Elsevier, 2014-07-01)Due to different deformation mechanisms arising from limited slip systems in HCP wrought magnesium alloys, their yield and hardening in tension and compression are different. Consequently, the cyclic behavior of these ... -
Asymmetric Graetz Problem: The Analytical Solution Revisited
(American Institute of Aeronautics and Astronautics, 2017-01-01)Forced-convective heat transfer from the walls of an asymmetrically heated channel to the fluid passing through in a laminar, hydrodynamically developed flow is known as the asymmetric Graetz problem. Several analytical ... -
Atmospheric Dispersion of Radionuclides Following Small Modular Reactor Accidents
(University of Waterloo, 2019-05-23)Small modular reactors (SMRs), reactors having a power rating of 300 Megawatts (MW) or less, have been under development for several decades. As fewer larger reactors are built due to the high upfront capital investment, ... -
Augmentation of Visual Odometry using Radar
(University of Waterloo, 2021-10-25)As UAVs become viable for more applications, pose estimation continues to be critical. All UAVs need to know where they are at all times, in order to avoid disaster. However, in the event that UAVs are deployed in an area ... -
