  1. 1. Voltage and power stability of HVDC systems

    Author : Denis Hau Aik Lee; KTH; []
    Keywords : ;

    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. 2. Modelling and Characterisation of Terahertz Planar Schottky Diodes

    Author : Aik-Yean Tang; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    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. 3. Modelling of Terahertz Planar Schottky Diodes

    Author : Aik-Yean Tang; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; S-parameter extraction; Electro-thermal; Schottky diodes; Skin effect; Electromagnetic; Frequency multipliers; High-power frequency multiplier; Current crowding; Proximity effect; Submillimetre wave generation and detection; Geometric modelling; Gallium Arsenide;

    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. 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

    Author : Jens Anker-Hansen; Maria Andrée; Per-Olof Wickman; Aik Ling Tan; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; scientific literacy; assessment; authentic; communities of practice; expansive learning; argumentation; peer assessment; moderation meetings; naturvetenskapsämnenas didaktik; Science Education;

    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. 5. "We can make new history here" : Rituals of producing history in Swedish football clubs

    Author : Katarzyna Herd; Avdelningen för etnologi; []
    Keywords : History; Football; AIK; Djurgårdens IF; Helsingborgs IF; Malmö FF; Collective memory; ritual; myth; Ethnology; narrativity; supporters; intertextuality;

    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.
