  1. 6. En grön oas mellan stad och natur : ett växtgestaltningsförslag över Triangelplatsen i Stockholm med fokus på Nigel Dunnetts metodik för naturalistiska planteringar

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Gustav Stål; Matilda Petersson; [2023]
    Keywords : naturalistiska planteringar; växtmix; ; växtsamhällen; ståndort; Nigel Dunnett; växtgestaltning;

    Abstract : Urbanisering, bostadsbrist och klimatförändringar är några av de faktorer som ställer högre krav på våra städer idag. Samhällen byggs i och med detta tätare och är i ständig omvandling för att anpassa sig till de problem som städerna ställs inför. I takt med urbaniseringen begränsas utrymmen till grönytor och grönska. READ MORE

  2. 7. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Therese Bäckström; [2023]
    Keywords : Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

    Abstract : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. READ MORE

  3. 8. Impact of Residual Stress on the Warm Pre-Stressing Effect

    University essay from KTH/Hållfasthetslära

    Author : Emil Danielsson; [2023]
    Keywords : Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

    Abstract : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. READ MORE
