  1. 1. Beam selection using Machine Learning in Massive MIMO systems

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Simon Persson; [2023]
    Keywords : Massive MIMO; Beamforming; Machine Learning; 5G; NR; Antenna selection; Technology and Engineering;

    Abstract : In mobile communications the demand for increased capacity and speeds is a constant. 5G NR is the latest generation which is now seeing widespread adoption. Crucial technologies like Massive MIMO and beamforming are enabled by the use of large antenna arrays. READ MORE

  3. 2. Investigating maintenance costs using response feature analysis

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Linus Hansson; [2022]
    Keywords : Response feature analysis; longitudinal data; maintenance costs; Response feature analysis; longitudinell data; underhållskostnader;

    Abstract : Svenska Kraftnät (Svk) is responsible for ensuring that Sweden has a safe, sustainable, and cost-effective transmission system for electricity. In an effort to reduce costs, Svk has participated in a study where it has been determined that there are mostly costs for common facilities that stand out cost-wise. READ MORE

  6. 5. Exploring the use of call stack depth limits to reduce regression testing costs

    University essay from Mittuniversitetet/Institutionen för data- och systemvetenskap

    Author : Patrik Bogren; Isak Kristola; [2021]
    Keywords : Regression Testing; Test Case Selection; Code Coverage; Dynamic Program Analysis; Execution Matrix;

    Abstract : Regression testing is performed after existing source code has been modified to verify that no new faults have been introduced by the changes. Test case selection can be used to reduce the effort of regression testing by selecting a smaller subset of the test suite for later execution. READ MORE
