    Sammanfattning : Asset management within the nuclear industry has become an increasingly relevant topic as safety requirements have tightened and energy security has become more important. Asset management ensures performance and reliability in a nuclear facility by balancing costs, opportunities, and risks to get the most out of assets. LÄS MER

  5. 4. Enhancing person re-identification: leveraging DensePose for improving occlusion handling and generalization

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Björn Elwin; Anton Fredriksson; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : In this master’s thesis we propose a DensePose-based person re-identification (re-ID) machine learning algorithm building upon previous research on this topic. DensePose, a deep neural network that performs human body part segmentation on images, forms the foundation of our approach. LÄS MER

  7. 5. Mathematical modeling and analysis of hot carrier solar cells

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen
