  1. 6. Feasibility Study of Resistivity Measurement of Metal Surfaces to Address Potential Dislocations Caused by Surface Conditioning

    Master-uppsats, Uppsala universitet/FREIA

    Författare :Mircea-George Coman; [2022]
    Nyckelord :;

    Sammanfattning : High electrical fields are needed inside the accelerating cavities of particle accelerators in order to accelerate the particles to higher energies in shorter distances. But high electrical fields will lead to electrical breakdowns. LÄS MER

  3. 7. Investigating and Modeling Uplink Processing in 5G NR Multisector Scheduler Simulator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Oskar Nygren; Axel Sneitz-Björkman; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. LÄS MER
