16. On some Numerical Methods and Solution Techniques for Incompressible Flow Problems
Sammanfattning : The focus of this work is on numerical solution methods for solving the incompressible Navier-Stokes equations, which consist of a set of coupled nonlinear partial differential equations.In general, after linearization and finite element discretization in space, the original nonlinear problem is converted into finding the solutions of a sequence of linear systems of equations.

17. Robust preconditioning methods for algebraic problems, arising in multi-phase flow models
Sammanfattning : The aim of the project is to construct, analyse and implement fast and reliable numerical solution methods to simulate multi-phase flow, modeled by a coupled system consisting of the time-dependent Cahn-Hilliard and incompressible Navier-Stokes equations with variable viscosity and variable density. This thesis mainly discusses the efficient solution methods for the latter equations aiming at constructing preconditioners, which are numerically and computationally efficient, and robust with respect to various problem, discretization and method parameters.

18. Doing well by doing good : The business model innovation process for sustainability in farm-based biogas production
Sammanfattning : Research on innovation that leads to change and adaptation in dynamic business environments has increased rapidly in recent decades. This doctoral thesis, which focuses on business model innovation (BMI), contributes to that research with its examination of how businesses can alter their structures to create, deliver, and capture greater economic value as well as environmental and social value.
