  1. 16. Evolution and Differentiation of Large Icy Moons

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Piia Tomberg; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Purpose: In preparation of several future missions with the objective to research the large icy moons of the Solar System, it is necessary to have a cohesive understanding of the conditions that might lead to the formation of liquid oceans in these moons. The purpose of this work is to create a numerical model for simulating the temperature evolution of the cores of large icy moons. LÄS MER

  3. 17. Additiv tillverkning - En undersökning av processbyte från traditionella tillverkningsmetoder

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Daniel Slessarevich; Daniel Björk Ljunggren; [2021]
    Nyckelord :Additive manufacturing; PEEK; Titanium; Quality Requirements; Profitability; Additiv tillverkning; PEEK; Titan; Kvalitetskrav; Lönsamhet.;

    Sammanfattning : The conventional manufacturing methods, such as milling and turning, are reliable methods which makes them commonly used. These methods are capable of producing high precision details with high surface quality. But there are drawbacks and limitations. Many of these methods are expensive and require high production volume to be profitable. LÄS MER

  4. 18. Impact Damage Assessment : In collaboration with Saab aerostructures

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Julia Augustson; Madeleine Bogg; [2020]
    Nyckelord :;

    Sammanfattning : This project that has been executed in collaboration with Saab aerostructures deals with how three materials, aluminum, titanium and corrosion resistant steel react when they are affected by different energy levels. These energy levels serve the purpose of representing damages that can happen in storage and handling to components used in production. LÄS MER

  5. 19. Next generation expedition stove : A lead user approach to product development

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Frida Rybo; Alfred Söder; [2020]
    Nyckelord :Outdoor equipment; lead user approach; Gioia methodology; expedition; stove; Friluftsutrustning; lead user; Gioia; expedition; friluftskök;

    Sammanfattning : In 1996 Primus launched their expedition stove Multifuel, the first stove that could run on liquified petroleum gas (LPG), white gas, kerosene and aviation fuel. The multi-fuel stoves are part of the Primus expedition range of equipment. The line was designed and built to perform in extreme conditions. LÄS MER

  7. 20. Degradation of model biomedical Mg alloys in aqueous media
