    University essay from KTH/Matematik (Avd.)

    Author : Niclas Joshua Popp; [2023]
    Keywords : Diagonal estimation; randomized numerical linear algebra; low-rank approximation; matrix functions; Diagonalestimering; randomiserad numerisk linjär algebra; lågrankad approximation; matrisfunktioner;

    Abstract : Implicit diagonal estimation is a long-standing problem that is concerned with approximating the diagonal of a matrix that can only be accessed through matrix-vector products. It is of interest in various fields of application, such as network science, material science and machine learning. READ MORE

  5. 4. Lateral Stabilization of CLT Buildings - Modelling approaches

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Lina Holmqvist; Sanna Källman Gleisner; [2022]
    Keywords : Technology and Engineering;

    Abstract : Cross-laminated timber (CLT) is an environmentally positive building material with high stiffness and load-bearing capacity. In combination with a low self-weight, CLT is a beneficial material to use for the load-bearing structure of high-rise buildings. READ MORE

  6. 5. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers

    University essay from KTH/Teknisk mekanik

    Author : Martina Formichetti; [2022]
    Keywords : Atmospheric boundary layer; turbulence modelling; stratified flows; eddy viscosity; eddy diffusivity;

    Abstract : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. READ MORE
