Wind Shear, Gust, and Yaw-Induced Dynamic Stall on Wind-Turbine Blades
(2016-05-31)This study examined the effect of a spanwise angle of attack gradient on the growth and stability of a dynamic stall vortex in a rotating system. It was found that a spanwise angle of attack gradient induces a corresponding ... -
Wing Kinematics and Flexibility for Optimal Manoeuvring and Escape
Understanding how animals control the dynamic stall vortices in their wake is critical to developing micro-aerial vehicles and autonomous underwater vehicles, not to mention wind turbines, delta wings, and rotor craft that ... -
Workspace Generation for Wire-Actuated Parallel Manipulators
(2009-10-20)This thesis focuses on the methods and results of the workspace formulation of wire-actuated parallel manipulators. Four methods of workspace generation are studied. The null space method, based on the calculation of wire ... -
Wrist Motion Simulation With a Rigid Body Spring Model Comparing Different Elements Modeling Approaches
(2016-04-08)A rigid body spring model was used to simulate wrist motions. The carpal bones were constructed based on a computed tomography of a cadaver wrist. Bony structures were assembled as a wrist model in the simulation software, ... -
Yielding Behaviour of Electron Beam Lithography and Focused Ion Beam Made Nanocrystalline Micro/Nanopillars
(2016-10-03)Electron beam lithography (EBL) and focused ion beam (FIB) methods were developed in house to fabricate nanocrystalline nickel micro/nanopillars so to compare the effect of fabrication on plastic yielding. EBL was used to ...
