  1. 1. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    Kandidat-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

    Författare :Khalil Daloul; [2023]
    Nyckelord :Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Sammanfattning : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. LÄS MER

In which high technology startup firms are playing an important role in introducing innovative and advanced technologies. However, due to inherent difficulties in nature, they face major challenges such as acquiring sufficient investments. LÄS MER

  7. 5. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lingyu Chen; [2022]
    Nyckelord :Modular multilevel converters MMC ; interleaved half-bridge submodule; interleaved converters; power loss calculation; converter efficiency; converter dimensions; Modulära multilevel-omvandlaren; interfolierad halvbrygga submodul; interfolierade omvandlare; effektförlustberäkning; omvandlareffektivitet; omvandlardimensioner;

    Sammanfattning : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. LÄS MER
