  1. 1. Using search based methods for beamforming

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Adam Bergman Karlsson; [2024]
    Nyckelord :Beamforming; Artificial Intelligence; AlphaZero; Radio Resource Management; Monte Carlo Tree Search;

    Sammanfattning : In accommodating the growing global demand for wireless, Multi-User Multiple-Input and Multiple-Output (MU-MIMO) systems have been identified as the key technology. In such systems, a transmitting basestation serves several users simultaneously, increasing the network capacity. LÄS MER

  5. 4. Stöldsskyddssystem : Designat för båtar och båtmotorer

    Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Oskar Hildestrand; [2021]
    Nyckelord :;

    Sammanfattning : Stölder av båtar och speciellt utombordsmotorer är ett stort problem i Sverige. Idag stjäls cirka 2000 utombordsmotorer varje år och det finns därför ett stort behov av effektiva stöldskyddssystem bland båtklubbar och båtägare. LÄS MER

  7. 5. Building and Evaluating a Full Disk Encrypted Secure Multi-user Operating Platform in Linux

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

    Författare :Peter Boström; [2021]
    Nyckelord :;

    Sammanfattning : Security is more important than ever, and since we are storing much of our sensitive data on hard drives, the demand for security systems is high. Full disk encrypted systems where multiple users can decrypt the same hard drive using the same secret but with different credentials are not common and is something that the military and various companies demand.
