1. Discretizations of nonlinear dissipative evolution equations. Order and convergence
Sammanfattning : The theme of this thesis is to study discretizations of nonlinear dissipative evolution equations, which arise in e.g. advection-diffusion-reaction processes. LÄS MER
2. Ghosts and machines : regularized variational methods for interactive simulations of multibodies with dry frictional contacts
Sammanfattning : A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts---machines. LÄS MER
3. Prediction horizon requirement in control and extreme load analyses for survivability : Advancements to improve the performance of wave energy technologies
Sammanfattning : The main objective of wave energy converters (WECs) is to ensure reliable electricity production at a competitive cost. Two challenges to achieving this are ensuring an efficient energy conversion and offshore survivability. LÄS MER
4. Linear response theory: from black holes to Weyl systems and back
Sammanfattning : Linear response theory is a powerful calculation tool in quantum field theory. We apply this framework to a variety of models originating from distinct areas in theoretical physics and for different reasons. LÄS MER
5. Critical Scaling in Particle Systems and Random Graphs
Sammanfattning : The purpose of this thesis is to study the behavior of macro-systems through their micro-parameters. In particular, we are interested in finding critical scaling in various models.Paper I investigates the influence of discrete-time collisions on particle dynamics. LÄS MER
