  5. 4. Machine Learning Methods for Segmentation of Complex Metal Microstructure Features

    Master-uppsats, KTH/Materialvetenskap

    Författare :Daniel Fredriksson; [2022]
    Nyckelord :Machine learning; Metallography; Automatic segmentation; Complex microstructures; Random Forest classifier.; Maskininlärning; Metallografi; Automatisk segmentering; Komplex mikrostruktur; Random Forest klassificerare;

    Sammanfattning : Machine learning is a growing topic with possibilities that seems endless with growing areas of applications. The field of metallography today is highly dependent on the operators’ knowledge and technical equipment to perform segmentation and analysis of the microstructure. Having expert dependents is both costly and very time-consuming. LÄS MER

  7. 5. Towards sustainable shipping: Recommendations for the telescopic mast design of a sailing cargo vessel

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Lukas Blau; [2021]
    Nyckelord :Oceanbird; telescopic mast; conceptual design; sailing cargo vessel;

    Sammanfattning : A comparative study is carried out to investigate the most promising route towardsthe lightweight construction of a retractable mast for a sailing cargo vessel.Four design families are developed and compared. The primary criteria forjudgment are the structural mass, strength, and stiffness in relation to a providedbenchmark design. LÄS MER
