  1. 1. LEO Satellite Connectivity for flying vehicles

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

    Författare :Jinxuan Chen; [2023]
    Nyckelord :LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

    Sammanfattning : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

  2. 2. LDPC DropConnect

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

    Författare :Xi Chen; [2023]
    Nyckelord :Bayesian approach; Machine learning; Coding theory; Measurement uncertainty; Algorithms; Bayesiansk metod; Maskininlärning; Kodningsteori; Mätosäkerhet; Algoritmer;

    Sammanfattning : Machine learning is a popular topic that has become a scientific research tool in many fields. Overfitting is a common challenge in machine learning, where the model fits the training data too well and performs poorly on new data. LÄS MER

  3. 3. How does the character’s visual design help convey the character’s background in Genshin Impact

    Kandidat-uppsats, Uppsala universitet/Institutionen för speldesign

    Författare :Chang Ge; Danyang Chen; [2023]
    Nyckelord :video games; character design; visual elements; character background; Genshin Impact;

    Sammanfattning : This study examines the relationship between the visual design of characters in thevideo game Genshin Impact and their character background. The study uses formal analysisand data collected on selected characters’ color choices, shapes, movements, facialexpressions, and backstories to analyze if the characters’ visual designs align with theirnarratives.

  4. 4. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules

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

    Författare :Lingyu Chen; [2022]
    Nyckelord :Modular multilevel converters MMC ; interleaved half-bridge submodule; interleaved converters; power loss calculation; converter efficiency; converter dimensions; Modulära multilevel-omvandlaren; interfolierad halvbrygga submodul; interfolierade omvandlare; effektförlustberäkning; omvandlareffektivitet; omvandlardimensioner;

    Sammanfattning : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. LÄS MER

  5. 5. Alteration of the forest structure in historically impacted Nothofagus spp. forests on the Brunswick peninsula : recommendations for their protection and management

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Leon Hauenschild; [2022]
    Nyckelord :Nothofagus spp. forests; Brunswick peninsula; Forest history; Indigenous land use; Holistic conservation;

    Sammanfattning : Despite exhibiting a seemingly low degree of human alteration when compared to other types of landscapes, most forest ecosystems in the world have a long history of human use and are prod-uct thereof. The southern Brunswick peninsula is no exception to this and has an extensive history of anthropogenic activity, both pre-colonial and modern. LÄS MER
