  1. 1. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Eglantin Gjoni; [2023]
    Keywords : ;

    Abstract : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. READ MORE

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

    University essay from KTH/Jord- och bergmekanik

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

    Abstract : 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. READ MORE

  4. 3. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device

    University essay from KTH/Geoinformatik

    Author : Kepan Gao; [2022]
    Keywords : U-Net; deep learning; tunnel monitoring; structural health monitoring; crack detection; mobile mapping system;

    Abstract : Infrastructures like bridges and tunnels are significant for the economy and growth of countries, however, the risk of failure increases as they getting aged. Therefore, a systematic monitoring scheme is necessary to check the integrity regularly. READ MORE

  5. 4. Design of tunnel support for single zones with swelling clay
