1. Voltage and power stability of HVDC systems
Abstract : This research work had been motivated by the emergence of multiple HVDC links in close proximity within a power system area, such as those in Southem Scandinavia and Northem Europe. Such system tonfigurations, generally known as multi-infeed HVDC systems, are expected to exhibit voltage and power stability problems when one or more of the constit uent AUDC interconnections are weak.

2. Modelling and Characterisation of Terahertz Planar Schottky Diodes
Abstract : This thesis deals with the modelling and characterisation of THz planar Schottky diodes, focusing on analyses of geometry-dependent electrical parasitics and the thermal management of the diode chip. Moving towards higher operating frequencies, the diode performance degrades due to high frequency losses, parasitic couplings and self-heating effects. READ MORE

3. Modelling of Terahertz Planar Schottky Diodes
Abstract : This thesis deals with the modelling of THz planar Schottky diodes, focusing on analyses of the geometry- dependent parasitics and the diode chip thermal management. Moving towards higher operating frequencies, the electromagnetic couplings pose significant limitations on the diode performance. READ MORE

4. Assessing Scientific Literacy as Participation in Civic Practices : Affordances and constraints for developing a practice for authentic classroom assessment of argumentation, source critique and decision-making
Abstract : This thesis takes a departure from a view of scientific literacy as situated in participation in civic practices. From such a view, it becomes problematic to assess scientific literacy through decontextualised test items only dealing with single aspects of participation in contexts concerned with science.

5. "We can make new history here" : Rituals of producing history in Swedish football clubs
Abstract : This dissertation investigates how history is produced, what roles it plays, and what forms it takes in four Swedish football clubs – AIK, Djurgårdens IF, Helsingborgs IF and Malmö FF. The overreaching aim is to describe and analyse how history is produced and performed in football clubs, and the implications this development has for football and for the understanding of history.
