1. On the Analysis of DC Network Dynamics of VSC-based HVDC Systems
Sammanfattning : In this thesis, the dc network dynamics of VSC-HVDC systems is investigated through eigenvalue and frequency domain analysis. The eigenvalue analysis has been used to identify the factors that have an impact on the system stability. LÄS MER
2. Analysis of dc-network stability of VSC-based HVDC grids
Sammanfattning : This thesis presents a modelling approach for the investigation of dc-network stability in HVDC grids. It consists on dividing the system under analysis into subsystems such that their individual impact on the stability of the overall system can be studied. LÄS MER
3. Membrane-based nanocalorimetry for low temperature studies with high resolution and absolute accuracy
Sammanfattning : A differential, membrane-based nanocalorimeter has been designed and constructed for thermal studies of mesoscopic samples at low temperatures. The calorimeter is intended for sample masses from mg to sub-μg and a broad temperature range from above room temperature down to the sub-K region. LÄS MER
4. An rf-sputtering system and applications to amorphous zinc telluride films
Sammanfattning : This thesis describes the fabrication and study of amorphous zinc telluride films. Their behaviour on post thermal treatments including crystallization are investigated. LÄS MER
5. On transport theory of correlated mesoscopic systems
Sammanfattning : This thesis is about the theory of quantum transport through low dimensional correlated systems. Correlated systems are interacting many-particle systems where collective effects predominate over the individual properties of particles whereof they consist. Single particle approach to correlated systems would be essentially wrong. LÄS MER
