Fast Sweeping Methods for Steady State Hyperbolic Conservation Problems and Numerical Applications for Shape Optimization and Computational Cell Biology
… accuracy and the capability to resolve shocks. Fast sweeping methods are efficient iterative numerical schemes originally designed for solving stationary Hamilton-Jacobi equations. Their efficiency relies on Gauss-Seidel type nonlinear iterations, and a finite number of sweeping directions. We …

High Speed Wavelength Tuning of SGDBR Lasers for Optical Coherence Tomography Applications
… requires a laser light source that is capable of sweeping its wavelength quickly over the entire wavelength range of the tunable laser. Fast sweeping of the laser's wavelength enables real-time imaging of a wide surface area of the surface under test. This thesis will show that SGDBR lasers can be …

Fast Marching Methods - parallel implementation and analysis
Fast Marching represents a very efficient technique for solving front propagation problems, which can be formulated as partial differential equations with Dirichlet boundary conditions, called Eikonal equation: $F(x)|\nabla T(x)|=1$, for $x \in \Omega$ and $T(x)=0$ for $x \in \Gamma$, where …

Numerical Prediction of Drag Reduction and Interfacial Shapes Over Superhydrophobic Surfaces
… field by solving the Eikonal equation using fast sweeping methods, and $(ii)$ minimize surface energy based on the distance potential to reconstruct the surface. The physical process can be thought of as an elastic membrane that covers the data set which evolves under a gradient flow until it …
