A Numerical approach for the solutions of fluid dynamics problems in the presence of magnetic field
Oğlakkaya, Fatma Sidre; Bozkaya, Canan; Department of Mathematics (2018)
This thesis is conducted to investigate numerically the two-dimensional steady or unsteady, laminar flow of viscous, incompressible and electrically conducting fluids in complex geometries subject to either uniform inclined magnetic field or nodal magnetic sources. Specifically, the hydromagnetic natural/mixed convection of either conventional fluid or water-based nanofluid flow and the heat transfer are considered in irregular enclosures with wavy walls. The equations governing the steady magnetohydrodynam...

A Meta-Heuristic Paradigm for solving the Forward Kinematics of 6-6 General Parallel Manipulator
Chandra, Rohitash; Frean, Marcus; Rolland, Luc (2009-12-18)
The forward kinematics of the general Gough platform, namely the 6-6 parallel manipulator is solved using hybrid meta-heuristic techniques in which the simulated annealing algorithm replaces the mutation operator in a genetic algorithm. The results are compared with the standard simulated annealing and genetic algorithm. It shows that the standard simulated annealing algorithm outperforms standard genetic algorithm in terms of computation time and overall accuracy of the solution on this problem. However, t...
A novel modeling methodology and performance improvement technique for DMTL phase shifters
İstanbulluoğlu, İpek; Akın, Tayfun; Department of Electrical and Electronics Engineering (2006)
This thesis presents distributed MEMS transmission line (DMTL) phase shifters, emphasizing the circuit modeling and design as well as the performance improvement. A novel modeling methodology is introduced for DMTL unit sections, with bridge widths larger than 50 μm. The introduced model is compared with EM simulation results and the CLR modeling results. For structures with bridge widths larger than 50 μm, the introduced model fits the simulation results much better than the CLR model. The simulated struct...
