  1. 16. Evaluation of structurally controlled rockfall hazard for underground excavations in seismically active areas of the Kiirunavaara mine

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

    Author : Manuel Alberto Fuentes Espinoza; [2023]
    Keywords : Structurally controlled rockfalls; rockfalls due to seismic shaking; sublevel caving; fork layout; Unwedge; wedge analysis; deterministic analysis; probabilistic analysis;

    Abstract : Sublevel caving operations at great depths are subjected both to large stress concentrations that are redistributed as the mining front progresses and to mining-induced seismicity. This is the case for Kiirunavaara mine, Sweden’s largest underground mine. READ MORE

  3. 17. Occlusion-Aware Autonomous Highway Driving : Tracking safe velocity bounds on potential hidden traffic for improved trajectory planning

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

    Author : Jonne van Haastregt; [2023]
    Keywords : Autonomous Driving; Occlusion-Awareness; Reachability Analysis; Highway driving; Formal Safety; Autonom Körning; Skymd-sikt-medveten; Nåbarhetsanalys; Motorvägskörning; Formell Säkerhet;

    Abstract : In order to reach higher levels of autonomy in autonomous driving, it is important to consider potential occluded traffic participants. Current research has considered occlusion-aware autonomous driving in urban situations. READ MORE

  4. 18. Risk Assessment for Space Debris Collisions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Kenny Andersson; [2023]
    Keywords : space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

    Abstract : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. READ MORE

  5. 19. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Adam Hjalmarsson; Leon Ericsson; [2023]
    Keywords : 4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Abstract : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.

  6. 20. Moon plasma environment and its implications for lunar space missions

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Mirko Viviano; [2023]
    Keywords : ;

    Abstract : This study investigates the lunar plasma environment and its implications for the safety and success of future crewed missions to the Moon. The Moon’splasma environment, formed by the solar wind, galactic cosmic rays and solar flare particles, presents potential hazards to human life and property. READ MORE
