1. Numerical Methods for Wave Propagation : Analysis and Applications in Quantum Dynamics
Sammanfattning : We study numerical methods for time-dependent partial differential equations describing wave propagation, primarily applied to problems in quantum dynamics governed by the time-dependent Schrödinger equation (TDSE). We consider both methods for spatial approximation and for time stepping. LÄS MER
2. Approaches to accelerate methods for solving systems of equations arising in nonlinear optimization
Sammanfattning : Methods for solving nonlinear optimization problems typically involve solving systems of equations. This thesis concerns approaches for accelerating some of those methods. In our setting, accelerating involves finding a trade-off between the computational cost of an iteration and the quality of the computed search direction. LÄS MER
3. Topology Optimization of Fatigue-Constrained Structures
Sammanfattning : Fatigue, or failure of material due to repeated cyclic loading, is one of the most common causes of mechanical failures. The risk of fatigue in a load carrying component is often lowered by adding material, thereby reducing stresses. LÄS MER
4. Goal-setting and goal-achieving in transport policy
Sammanfattning : The thesis aims at developing new, alternative approaches and methods based on suggestions and ideas originating from moral philosophy and philosophical decision theory. More precisely, the thesis aims at investigating the rationality of transport policy decisions, including goal-setting and performance evaluation. LÄS MER
5. Simplified Nonsense: New Methods for Interrogating NMD
Sammanfattning : Nonsense mediated decay (NMD) is a pathway that regulates RNA turnover. Since its discovery, this pathway has been implicated in a variety of cellular processes ranging from differentiation to the restriction of viral replication. LÄS MER
