11. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.

13. Simulation of wire bending processes in continuous wave winding stator production
M1-uppsats, KTH/ProduktionsutvecklingSammanfattning : Electric propulsion in the heavy truck industry require knowledge in certain new areas involved in electric machine manufacturing. One of these new manufacturing steps is copper bending for production of stator windings. LÄS MER
14. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. LÄS MER
15. Energy flows and potential energy development strategies in RoRo ports: A study based on the Port of Trelleborg
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : The recent push for decarbonization in the maritime sector presents an opportunity for ports to strengthen their position as energy hubs. This work studies the existing energy flows in the Port of Trelleborg, one of Europe's biggest roll-on, roll-off ports, and proposes some energy-related development strategies. LÄS MER
