  1. 1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

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

    Författare :Simon Weideskog; [2024]
    Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

  4. 3. Incorporation of climate effects in marine spatial planning. Possible Climate Refugia on the Swedish West Coast Based on Two Climate Scenarios

    Master-uppsats, Göteborgs universitet/Institutionen för marina vetenskaper

    Författare :Eric Strömberg; [2023-08-11]
    Nyckelord :Climate Refugia; Climate Change; Representative Concentration Patterns; Marine Spatial Planning; Geographical Information Systems; Temperature; Salinity; Marine Management; Swedish West Coast;

    Sammanfattning : Climate change poses a significant threat to the survival and distribution of marine species and habitats. Identification and conservation of climate refugia have emerged as a strategy to safeguard vulnerable habitats and promote species resilience. LÄS MER

  5. 4. Turning the tide on marine biodiversity loss: How Swedish coastal cities are leveraging citizen interaction to improve conservation outcomes

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Martine Deinum; [2023]
    Nyckelord :Marine spatial planning; urban planning; blue space; program theory; citizen interaction; coastal conservation; Earth and Environmental Sciences;

    Sammanfattning : Rapid coastal urbanization and declining marine biodiversity rates are complex problems that require broad, integrated sets of solutions. Although isolating nature from human impact prevails as the standard conservation approach, social-ecological systems require more holistic solutions. LÄS MER

  7. 5. Studies on future Mine Countermeasure Vessels (MCMV)

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Författare :Philip Somehagen; [2023]
    Nyckelord :Concept development; Mine countermeasure vessels; ROV; Sonar; Konceptutveckling; Minjaktsfartyg; ROV; Sonar;

    Sammanfattning : Background Maritime transportation is vital for international trade, and any disruption to this flow can have severe financial and environmental consequences. Ship mines, both old and new, present significant risks as man-made obstacles. LÄS MER
