  1. 1. Experimental Evaluation of Spray Reduction Technologies

    Master-uppsats, KTH/Marina system

    Författare :Svante Lundmark; [2019]
    Nyckelord :;

    Sammanfattning : This report concerns the efficiency of a novel spray deflector design. The novel design is analyzed and compared to a bare hull and a bare hull fitted with spray rails by experimental testing in a towing tank. LÄS MER

  2. 2. Böjprovning av spikplåtsskarvad träbalk

    M1-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik; Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Ebubekir Korkmaz; Jerry Lundstöm; [2019]
    Nyckelord :Construction timber; nail plate fastener; strength; moment; shear; stiffness.; Konstruktionsvirke; Spikplåt; Hållfasthet; Moment; Tvärkraft; Styvhet.;

    Sammanfattning : This thesis examines the bearing capacity, stiffness, shear and moment force of a continuous wooden beam and how the parameters of the beam changes when the beam is spliced ​​with nail plate. A literature study has been conducted to examine which studies have been carried out in this field. LÄS MER

  3. 3. OPTIMIZATION OF NOZZLE SETTINGS FOR A FIGHTER AIRCRAFT

    Master-uppsats, Mälardalens högskola/Industriell ekonomi och organisation; Mälardalens högskola/Industriell ekonomi och organisation

    Författare :Alexander Stenebrant; Nor Al-Mosawi; [2019]
    Nyckelord :Low-bypass turbofan; afterburner; convergent-divergent nozzle; afterbody drag; computational fluid dynamics.;

    Sammanfattning : Most fighters use the convergent-divergent nozzle configuration to accelerate into the supersonic realm. This nozzle configuration greatly increases the thrust potential of the aircraft compared to the simpler convergent nozzle. LÄS MER

  4. 4. Design of Ultra High Performance Fibre Reinforced Concrete Bridges : A Comparative Study to Conventional Concrete Bridges

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Viktor Eriksson; [2019]
    Nyckelord :Bridge design; CO2 emissions; Mechanical properties and behaviour; Straight short steel fibres; UHPC; UHPFRC; Bro dimensionering; CO2 utsläpp; Korta raka stålfibrer; Mekaniska egenskaper och beteende; UHPC; UHPFRC;

    Sammanfattning : The use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in the construction industry started in the 1990s and has since then been used for bridges all over the world. The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed.

  5. 5. Grasshoppers Rather Than Ants? - Ideal Victims, Just-World Belief and the Reduction of Victim Compensation in Swedish Law

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Författare :Joseph Goss; [2019]
    Nyckelord :criminal law; tort law; criminal injuries compensation; ideal victim; just-world; Law and Political Science;

    Sammanfattning : Monetary compensation to victims of crime can take different forms and be paid by different actors. The rules for calculating the compensation sometimes mandate reduction of the amount awarded for various reasons. This reduction can potentially be experienced by victims as a “secondary victimisation”. LÄS MER
