  1. 11. 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

  2. 12. Fake Mass-Produced Advertisements Detection on Global Online Adult Service Websites

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

    Författare :Ernest Pokropek; [2023]
    Nyckelord :Machine learning; Spam detection; Mass-produced spam; Global adult online services; Maskininlärning; Detektering av Spam; Massproducerad Spam; Globala Webbplatser som Erbjuder Eskorttjänster;

    Sammanfattning : A significant amount of sex trafficking victims are being advertised on online adult services, which are currently being flooded with spam. Investigators rely on online adult services to track cases of sex trafficking; however, the ever-increasing volume of spam poses a mounting challenge, making their task progressively more difficult.

  3. 13. Ray Tracing Algorithm for Dielectric Domes

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

    Författare :Maria Pubill; [2023]
    Nyckelord :Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Sammanfattning : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. LÄS MER

  4. 14. Constellation Optimization using Genetic Algorithm : Combining SAR & Optical Sensors with AI Requirements

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

    Författare :Adrian Pellnäs; [2023]
    Nyckelord :Satellite Constellation Design; Satellite Constellation Optimization; AI - Artificial Intelligence; Synthetic Apterture Radar; Dual-axis; RegionalCoverage Analysis; Satellitkonstellationsdesign; Optimering av satellitkonstellationer; AI - Artificiell Intelligens; Syntetisk Apertur Radar; Dual-axis; Analys avregional täckning;

    Sammanfattning : With increasing world tensions and improvements of satellites and their sensors, the interest and possibility of using space and satellites for defensive purposes has increased greatly. However, not much research has been conducted into the needs and possibilities of satellite constellations over Sweden, especially using SAR and optical sensors combined with AI object detection.
