11. CVD solutions for new directions in SiC and GaN epitaxy
Sammanfattning : This thesis aims to develop a chemical vapor deposition (CVD) process for the new directions in both silicon carbon (SiC) and gallium nitride (GaN) epitaxial growth. The properties of the grown epitaxial layers are investigated in detail in order to have a deep understanding. LÄS MER
12. Convection-diffusion-reaction models of sedimentation : Numerical approximation, analysis of solutions and inverse problems
Sammanfattning : The core of this Doctoral thesis is mainly based in the studies of one-dimensional initial-boundary value problems, which are given by a single non-linear hyperbolic partial differential equation (PDE) with non-convex flux function, or by a system of strongly degenerate parabolic PDEs, for the simulation of sedimentation processes of solid particles immersed in a fluid. Particular attention is paid to the case of settling in vessels with varying cross-sectional area. LÄS MER
13. Prediction of Wing Section Lift and Drag from Numerical Solutions of the Navier-Stokes Equations
Sammanfattning : A Navier-Stokes finite difference method is developed and applied to two-dimensional, incompressible, viscous flow around wing sections at medium to high Reynolds numbers. An important feature of such flows is laminar boundary layers with spatially amplified Tollmien-Schlichting waves initiating transition to turbulence. LÄS MER
14. Some matters of great balance
Sammanfattning : This thesis is based on four papers dealing with two different areas of mathematics.Paper I–III are in combinatorics, while Paper IV is in mathematical physics.In combinatorics, we work with design theory, one of whose applications aredesigning statistical experiments. LÄS MER
15. Least squares rigid body fitting of point-sets with unknown correspondences
Sammanfattning : The problem addressed here is: given points u_1,...,u_n and v_1,. LÄS MER
