  3. 2. Future Electricity Consumption and Wind Power Production in Sweden - Effects of Climate Change

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Ingrid Torstensson; [2021]
    Nyckelord :Electricity system; Bias Correction; Quantile Mapping; Climate Model; Emission scenarios; Mathematics and Statistics;

    Sammanfattning : To maintain stability in the Swedish electricity grid, Svenska kraftnät must be able to predict future electricity production and consumption. Earlier this have been done by using historical data. LÄS MER

  4. 3. Method to assess machinability of engineering steels using coated carbide tools

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Petra Hedberg; [2021]
    Nyckelord :Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

    Sammanfattning : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested.

  5. 4. Reduced Order Modelling using Dynamic Mode Decomposition and Koopman Spectral Analysis with Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :David Krantz; Olof Månsson; [2020]
    Nyckelord :non-linear dynamical systems; modal decomposition; Koopman operator theory; machine learning; data-driven analysis; Mathematics and Statistics;

    Sammanfattning : In the industry simulation models are commonly used in system development. These models can become complicated in order to capture the physical behaviour of the underlying dynamical system. A high-fidelity representation, which can result in long simulation times, is in some settings not strictly required. LÄS MER

  7. 5. Smoothed Aggregation for Nonsymmetric Linear Systems

    Master-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematikcentrum

    Författare :Siobhan Correnty; [2019]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Smoothed Aggregation (SA) is a technique from algebraic multigrid methods (AMG) which has shown very promising results when solving systems of linear equations with symmetric system matrices, but suboptimal results for nonsymmetric system matrices. The purpose of this thesis is to investigate the method EMIN(r) and a closely related method EMIN proposed by Sala and Tuminaro. LÄS MER
