  1. 11. Void formation and transport in manufacturing of polymer composites

    Författare :Staffan Lundström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : In this thesis void formation and removal during the Resin Transfer Moulding process are considered. The problem is examined by doing real moulding as well as mouldings under microscope, model experiment and analytical computations. The materials utilised are in most cases glass fibre reinforcements and vinylester resins. LÄS MER

  3. 12. Initial stages of metal- and organic-semiconductor interface formation

    Författare :Pål Palmgren; Mats Göthelid; Mikael Grehk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductor physics; Halvledarfysik;

    Sammanfattning : This licentiate thesis deals with the electronic and geometrical properties of metal-semiconductor and organic-semiconductor interfaces investigated by photoelectron spectroscopy and scanning tunneling microscopy. First in line is the Co-InAs interface (metal-semiconductor) where it is found that Co is reactive and upon adsorption and thermal treatment it alloys with the indium of the substrate to form metallic islands, about 20 nm in diameter.

  4. 13. Modeling Auto-Ignition, Flame Propagation and Combustion in Non-Stationary Turbulent Sprays

    Författare :Anders Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; auto-ignition; transient; flame propagation; turbulence; spray formation; prediction; stirred reactor approximation; model; reduced chemistry; combustion;

    Sammanfattning : This thesis focuses on detailed numerical studies of spray formation, auto-ignition, envelope flame development and combustion in a simple two-dimensional axi-symmetric geometry. A Lagrangian -- Eulerian formulation is used to analyze the droplet motion and gas flow field. LÄS MER

  5. 14. A quantum-chemical study to the magnetic characteristics of methanol and its applications in astronomy

    Författare :Boy Lankhaar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methanol; maser polarization; star formation; magnetic fields; masers;

    Sammanfattning : Magnetic fields play an important role during star formation. Direct magnetic field strength observations have proven specifically challenging in the dynamic protostellar phase. LÄS MER

  7. 15. Ceremoniernas makt : Maktöverföring och genus i Vasatidens kungliga ceremonier

    Författare :Malin Grundberg; Olle Ferm; Svante Norrhem; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Early modern history; the Vasa period; royal ceremonies; coronations; royal funerals; ritual; rites of passage; ritual interaction; gender; masculinity; femininity; unmanliness; state formation; power legitimation; invented tradition; Gustav Vasa; Erik XIV; Johan III; Gustav II Adolf; Queen Kristina; Karl X Gustav; History subjects; Historieämnen;

    Sammanfattning : This dissertation studies the royal ceremonies of the Vasa era in Sweden. The ceremonies connected with two Swedish monarchs – Erik XIV and Queen Kristina – is examined. From the sixteenth century I study Gustav Vasa’s funeral 1560, Erik XIV’s coronation 1561, Erik’s deposition 1568/69 and his brother Johan’s coronation 1569. LÄS MER
