  1. 11. Formation Control of UAVs for Positioning and Tracking of a Moving Target

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Robert Carsk; Alexander Jeremic; [2023]
    Nyckelord :Autonomous; UAVs; Drones; Sensor Fusion; MPC; Filter; KF; EKF; Signal; Tracking; Formation; Controller; Control; MWSN; Optimal Control Problem; Optimization; Seeker Drone; Target Drone; Quadcopter Model; Simulation;

    Sammanfattning : The potential of Unmanned Aerial Vehicles (UAVs) for surveillance and military applications is significant — with continued technical advances in the field. The number of incidents where UAVs have intruded into unauthorized areas has increased in recent years and armed drones are commonly used in modern warfare. LÄS MER

  3. 12. Demonstration of Digital Selective Call spoofing

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Axel Lindbäck; Yamha Javid; [2023]
    Nyckelord :Digital Selective Calling; Software Defined Radio; Spoofing; Cybersecurity; Maritime Communication Systems;

    Sammanfattning : Digital Selective Calling (DSC) is a vital maritime communications and safety system, enabling ships in distress to alert nearby vessels and coast guard stations of their emergency. While DSC is suitable for calling, its technical format is substandard from a cybersecurity perspective. LÄS MER

  4. 13. Damage Analysis of Reactive Ion and Atomic Layer Etched Silicon

    Magister-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Mohammad Al Abrash; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Dry etching is one of the most important methods of pattern transfer in nanofabrication. There are many dry etching methods, the most commonly used is reactive ion etching (RIE), that is based on a continuous supply of reactive ions and radicals generated in a radio-frequency (RF) plasma discharge.

  5. 14. MPC for the Slow Orbit Feedback Control at MAX IV

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Emory Gassheld; My Karlsson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The MAX IV synchrotron radiation facility in Lund is designed to produce bright and high-energy X-ray radiation. One important component of achieving this is to keep the electron beam inside the storage rings centered and stable. LÄS MER
