  4. 3. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    University essay from KTH/Lättkonstruktioner

    Author : Luis Alfonso Penela Guerrero; [2022]
    Keywords : Aerospace; wind tunnel testing; lightweight structures; UAV; composite materials; Flyg; vindtunneltestning; Lättkonstruktioner; UAV; kompositmaterial;

    Abstract : The use of wind tunnel models for aerodynamic research is nowadays indispensable to aviation progress in the last years as aircrafts have become more complex. Wind tunnel model design and manufacturing has adopted many different processes and materials such as the use of a five-axis CNC; making this process a relatively long and expensive one. READ MORE

  5. 4. Groundwater Inflow into Fractured Rock Tunnels

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mariam Beydoun; [2022]
    Keywords : groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

    Abstract : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. READ MORE

  6. 5. Artificial Intelligence applications for railway signalling

    University essay from KTH/Transportplanering

    Author : Benjamin Smakic; [2021]
    Keywords : Artificial Intelligence; AI; Machine Learning; ML; Computer Vision; railway signalling; ERTMS level 3; GPS; autonomous train operations; Artificiell Intelligens; Maskininlärning; datorseende; signalteknik; autonoma tåg; självkörande tåg.;

    Abstract : The main purpose of this Master Thesis is to investigate how front-facing, train-mounted cameras and Computer Vision, a type of Artificial Intelligence (AI), can be used to compensate for GPS inaccuracies. By using footage from track-recording cameras, Computer Vision can be utilized to determine the number of tracks and the track occupancy of the train, which would compensate GPS inaccuracies in the lateral positioning.
