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

    University essay from Uppsala universitet/Tillämpad beräkningsvetenskap

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

    Abstract : 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. READ MORE

  3. 2. Fabrication of sub-10 nm solid-state nanopores by electrical breakdown

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

    Author : Kasumi Tsutsumi; [2023]
    Keywords : Nanopore fabrication; Solid-state material; Silicon nitride; Graphene; DNA translocation; Nanopor-avkänning; fast tillståndsmaterial; kiselnitrid; grafen; DNA-translokation;

    Abstract : Nanopore sensing is a versatile technique that employs very small openings, known as nanopores, to study biomolecules. The use of nanopores on solid-state membranes has gained attention due to its potential for low-cost and high-throughput sensing of single molecules in liquids. READ MORE

  5. 4. Battery Balancing on a Full-Bridge Modular Multi-Level Converter

    University essay from Linköpings universitet/Fordonssystem

    Author : Junyu Lin; [2022]
    Keywords : MMC; BMS; Modular Multilevel Converter; SOC; state of charge;

    Abstract : Batteries are becoming popular in the trend of electrification. Performance andlifespan of a battery pack are closely related to how it has been utilized. Withproper balancing control to slow down aging process, variances of capacity andresistance between battery cells can be maintained at a better level. READ MORE

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

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

    Author : Lingyu Chen; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE
