  1. 1. Machine Learning-based MIMO Indoor Positioning

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Qiyi Chen; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER

  3. 2. Optimization of Material Cost and Carbon Footprint of Flat Reinforced Concrete Slabs with Simple Steel Piles : Designed according to Eurocode and Swedish appendix EKS

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Oskar Lönn; [2023]
    Nyckelord :Optimization; RC slab; Material cost; API;

    Sammanfattning : When designing reinforced concrete (RC) slabs with steel piles various variables must be considered, from the internal force to the distance of piles. An endless number of designs are possible, leaving space for optimizing designs. LÄS MER

  4. 3. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Ida Schjelderup; [2022]
    Nyckelord :Jet grouting; jet grout bottom plug; cut-and-cover tunnel; tunnel design;

    Sammanfattning : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. LÄS MER

  5. 4. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Kent Nystedt; [2022]
    Nyckelord :Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Sammanfattning : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. LÄS MER

  7. 5. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure

    Master-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Amanda Byström; [2022]
    Nyckelord :Milky Way; Galactic archaeology; halo; photometric metallicities; stellar catalogue; Gaia-Enceladus-Sausage; Sagittarius; Pristine survey; metallicity; Gaia mission;

    Sammanfattning : The Milky Way galaxy, like all spiral galaxies, is surrounded by a roughly spherical distribution of stars called the halo. The halo was largely formed when the galaxy merged with smaller galaxies. LÄS MER
