  1. 1. Design of a vacuum chamber for cathode testing and low power Hall Effect Thrusters : Collaborative project with OHB Sweden AB

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Andrea Martinez Sanz; [2023]
    Nyckelord :Vacuum chamber; adaptability; hollow cathode test; fluid ground support equipment; low power Hall Effect Thrusters test; Vakuumkammare; anpassningsförmåga; ihålig katod testa; flytande markstödutrustning; låg effekt Hall Effect Thrusters testa;

    Sammanfattning : Testing of hardware to be used in space sometimes involves using vacuum chambers. The need to test hollow cathodes, used as neutralizers for some Electric Propulsion Thrusters, and low power Hall Effect Thrusters at OHB Sweden requires a vacuum chamber to be upgraded. LÄS MER

  3. 2. Meditation som behandlingsmetod och dess effekt hos studenter med stress : En litteraturstudie

    Kandidat-uppsats, Uppsala universitet/Fysioterapi

    Författare :Didrik Hall; Linnea Andersson; [2023]
    Nyckelord :Mindfulness; meditation; stress; students; Perceived Stress Scale;

    Sammanfattning : Bakgrund: Stress är vanligt förekommande bland studenter och kan ge upphov till såvälpsykiska som fysiska besvär. Meditation som behandling skulle kunna vara ett alternativ förfysioterapeuter att motverka detta. LÄS MER

  4. 3. Development of Nickel-Titanium Shape Memory Alloys using Electron Beam Melting

    Master-uppsats, KTH/Materialvetenskap

    Författare :Georgios Manolios; [2022]
    Nyckelord :;

    Sammanfattning : In this project, the effect of electron beam melting on the behavior of NiTi shape memory alloyshas been studied, with focus on the effects of recycling powder within the process and theprocess parameters used and how “smoking” is affected. Flowability, powder characteristicsand chemical composition have been evaluated using imaging analysis techniques, Hallflowmeter measurements, FT4 powder rheometry and energy dispersive X-ray spectroscopyboth in virgin powder and in recycled powders.

  5. 4. Data center cooling solutions : A techno-economical case study of a data center in Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Joel Sjökvist; Fredrik Magnusson; [2022]
    Nyckelord :Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

    Sammanfattning : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. LÄS MER

  7. 5. Impact of Lecture Hall Layout on Evacuations Using Crowd Simulations

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Tobias Mattsson; Ernest Umeh; [2022]
    Nyckelord :Lecture hall; Evacuation; Simulation; Evacuation rate; Layout variation; Föreläsningssal; Evakuering; Simulation; Evakueringstakt; Layoutvariationer;

    Sammanfattning : The planning and preparation phases of emergency management are of great social interest. If appropriate safety measures can be implemented in buildings beforehand as a response to foreseeable hazards, the safety of individuals can be significantly increased. LÄS MER
