  1. 21. Design and Analysis of Non-symmetric Satellite Constellations

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Jomuel Danilo Costales; [2023]
    Nyckelord :Space; Satellite; Constellation; Coverage; Non-symmetric; Walker; Set Cover problem; Greedy algorithm; Space; Satellit; Constellation; Täckning; Icke-symmetrisk; Walker; Set Cover problem; Greedy algoritm;

    Sammanfattning : Satellite constellation design has been a well-studied problem since the beginning of the space age. In recent years new concepts and approaches tried to solve it with fewer satellites whilst guaranteeing coverage to the areas of interest, whether globally or regionally. LÄS MER

  3. 22. Map Based Sensor Fusion for Lane Boundary Estimation on ADAS

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

    Författare :Puya Faghi; [2023]
    Nyckelord :Lane estimation; Lane detection; Map-matching; Sensor fusion; Smart camera; Vehicle Radar; Intelligent vehicle systems; Körfältsestimering; Körfältsdetektering; Kartmatchning; Sensorfusion; Smart Kamera; Radar system; Fordonsradar; Intelligenta fordonssystem;

    Sammanfattning : A vehicles ability to detect and estimate its surroundings is important for ensuring the safety of the vehicle and passengers regardless of the level of vehicle autonomy. With an improved road and lane estimation, advanced driver-assistance systems will be able to provide earlier and more accurate warnings and actions to prevent a possible accident. LÄS MER

  4. 23. Deep Neural Networks for Object Detection in Satellite Imagery

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Frederik Fritsch; [2023]
    Nyckelord :Object Detection; Satellite Imagery; Deep Neural Networks; YOLOv8; xView;

    Sammanfattning : With the development of small satellites it has become easier and cheaper to deploy satellites for earth observation from space. While optical sensors capture high-resolution data, this data is traditionally sent to earth for analysis which puts a high constraint on the data link and increases the time for making data based decisions.

  5. 24. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Författare :Nick Bergmans; [2023]
    Nyckelord :satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Sammanfattning : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. LÄS MER

  7. 25. Temporal Projections of the Shoreline Displacement on Gotland

    Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Yonathan Tekeste; [2023]
    Nyckelord :Sea Level Rise; Shoreline Displacement; Gotland;

    Sammanfattning : Global mean sea level rise (GMSLR) impacts the displacement of the world’s coasts and shorelinedifferently due to it being contingent on local topographic and geological conditions. The island of Gotlandis located in the Fennoscandian Shield which lies at the intersection between GMSLR and post-glacialrebound (PGR), at rates that vary latitudinally and, in some areas, are at equal levels.
