  1. 1. Prototype of a Range Prediction Interface for an Electric Rescue Boat

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

    Author : Oskar Pålhagen; Erik Halme; [2023]
    Keywords : Electric rescue boat; Battery GUI; Range prediction; Prototyping; Elektrisk räddningsbåt; Batteri GUI; Avståndsestimering; Prototypframställning;

    Abstract : Global warming and its effects on the environment call for electrification of the transportation sector. In this effort, the boating industry has not been a pioneer, while being responsible for almost 3 percent of global anthropogenic carbon emissions. READ MORE

  3. 2. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anton Sandberg; [2023]
    Keywords : Framboidal pyrite; dredging; Sangis River; estuary; redox ladder; sediment; sediment cores; SEM-EDS;

    Abstract : It has been common in forestry and agriculture to drain waterlogged areas through ditching in order to cultivate them. The ditches that drain water are usually connected to some watercourse, such as a river. READ MORE

  4. 3. Online Parameter Estimation of a Six- Phase Machine for Marine Application

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

    Author : Raimundo Montalba Mesa; [2021]
    Keywords : Multiphase electrical machines; IPSM; Parameter estimation; Online estimation; Stator resistance estimation; Permanent magnet flux estimation.; Flerfas elektriska maskiner; IPSM; Parameteruppskattning; Online uppskattning; Statorresistans uppskattning; Flödesuppskattning av permanentmagneter.;

    Abstract : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. READ MORE

  5. 4. Electrically powered manoeuvring of water jets

    University essay from Uppsala universitet/Industriell teknik

    Author : Joel Engström; [2021]
    Keywords : Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Abstract : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.
