  4. 3. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Niklas Gunnarsson; [2019]
    Nyckelord :Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Sammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER

  5. 4. Design and manufacture of structure and hull for large AUV

    Master-uppsats, KTH/Marina system

    Författare :Billy Vendel Olofsson; [2018]
    Nyckelord :;

    Sammanfattning : The main goal with the master thesis was to design and manufacture a frame and hull to a large AUV which KTH will use in research. The general aim for the Maribot LoLo (Long Endurance, Long Range AUV) is to act as an experimental platform and tool for a wide range of research activities, where all four capabilities within the SMaRC area (Autonomy, Perception, Endurance and Communication) can be tested, improved and demonstrated.

  7. 5. Evaluation of current welding robot and improvement proposals for future use

    Master-uppsats, KTH/Marina system

    Författare :Joakim Nilsson; [2018]
    Nyckelord :;

    Sammanfattning : Welding of elements, a heat exchanging component, is one of the most essential processes during the manufacturing of Tubel evaporators. Weld joints consists of fillet welds of thin tubes against a plate on one end, and on the other end against a thicker pipe with entry holes for the tubes. LÄS MER
