    Author : Hanna Albertsson; Melina Isik; [2022]
    Keywords : bacteria oral microflora regional differences;

  3. 2. Optimization of support in rock pillars between two parallel tunnels

    University essay from KTH/Jord- och bergmekanik

    Author : Alexander Kote; Sohaib Ishaq; [2022]
    Keywords : tunnel; rock pillar support; rock pillar stability; rock mass; stresses; arching effect; Nyckelord: tunnel; bergförstärkning; bergpelare; bergmassa; spänningar; valveffekt;

    Abstract : When two parallel tunnels are excavated under high to moderate horizontal in-situ stresses combined with minor deformations in the pillar between the tunnels, the in-situ stresses can be redistributed over the tunnels in form of two compressive arches and are transferred from the roof to the abutments of the two tunnels. At additional deformations in the pillar, a new redistribution of the stresses can occur creating one compressive arch over both of the tunnels. READ MORE

  4. 3. Hydraulic Erosion Simulation on the GPU for 3D terrains

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sebastian Isheden; [2022]
    Keywords : Hydraulic Erosion; 3D erosion; CUDA; erosion; simulation; Vatten Erosion; 3D erosion; CUDA; erosion; simulering;

    Abstract : Erosion is the action of various natural processes, such as water flow, wind and gravity, that displaces material from one area to another. Creating physically-based models of these complex phenomena has been a major challenge in creating realistic terrain in video games in a fast way, without having a 3D artist model the terrain by hand.

  6. 5. Modelling masonry spires : An investigation

    University essay from KTH/Betongbyggnad

    Author : Dennis Lillemo; [2021]

    Abstract : Masonry spires are a typical part of church architecture. Since it is rare that masonry is used as a load-bearing material in the western world today, it is important to maintain and increase the knowledge of modelling masonry structures both from a maintenance point of view and to build new masonry structures.
