11. Gaps, Traps and Lattices - Correlations in Small Quantum Systems
Sammanfattning : This dissertation investigates properties of two-dimensional many-body systems. Studies are performed using the Spin-Density Functional Theory with the Local Spin-Density Approximation, and numerical exact diagonalization. LÄS MER
12. Drift-Type Waves in Rotating Tokamak Plasma
Sammanfattning : The concept of energy production through the fusion of two light nuclei has been studied since the 1950’s. One of the major problems that fusion scientists have encountered is the confinement of the hot ionised gas, i.e. the plasma, in which the fusion process takes place. LÄS MER
13. Protein Dynamics Studied by NMR Spin Relaxation. Conformational Transitions of a Calmodulin Mutant
Sammanfattning : Binding of calcium to the protein calmodulin leads to molecular reorganization that enables interaction with target peptides and activation of downstream processes. I have studied the dynamics of the calcium-loaded form of a C-terminal calmodulin mutant (E140Q-Tr2C) using NMR spin relaxation experiments. LÄS MER
14. Feedback control of resistive wall modes in the reversed field pinch
Sammanfattning : A wide range of unstable current driven MHD modes is present in the re- versed τeld pinch (RFP) conτguration. An ideally conducting wall facing the plasma can stabilize the ideal MHD modes. LÄS MER
15. Contributions to the electromechanics of unbalanced magnetic pull in a synchronous hydropower generator
Sammanfattning : Misalignment between the rotor geometrical axis and the geometrical stator axis in a hydropower generator is usually present at standstill and when the machine is under operation. Now, rotor-stator eccentricity in a rotating electrical machine is a harbinger to abnormal operating conditions of the machine. LÄS MER
