  1. 1. Development of a 2D Optimal Path Simulation for Ship-to-Shore Cranes : Safe Trajectories within Interchangeable Obstalce Environments

    University essay from Linköpings universitet/Fordonssystem

    Author : Rickard Green; [2020]
    Keywords : Optimal Path; Control; Control theory; Obstacle; Safe trajectories; LiU; ISY; Reglerteknik;

    Abstract : The most advanced ports as of writing of this report are at least somewhat autonomous. Whether discussing the transporters between crane and stack (temporary storage) or cranes, the ports are shifting into a completely autonomous system. This ultimate goal presents a challenge in regards to unloading and loading cargo ships in the harbour. READ MORE

  2. 2. Robust Autonomous Landing of Fixed-Wing UAVs in Wind

    University essay from Linköpings universitet/Reglerteknik

    Author : Tobias Fridén; [2020]
    Keywords : Unmanned Aerial Vehicles; Landing; Wind; Optimization; Motion planning;

    Abstract : Fixed-wing UAVs are today used in many different areas, from agriculture to search and rescue operations. Through various research efforts, they are becoming more and more autonomous. However, the procedure of landing a fixed-wing UAV remains a challenging task, which requires manual input from an experienced pilot. READ MORE

  3. 3. Lidar-based SLAM : Investigation of environmental changes and use of road-edges for improved positioning

    University essay from Linköpings universitet/Reglerteknik

    Author : Oskar Karlsson; [2020]
    Keywords : lidar-slam; environmental; road-edges; gtsam; isam; evaluation; road-edge detector; ros; robot operating system; weather; rain; snow; rosnodes; slam; imu; ekf; extended kalmar filter; evaluation measures;

    Abstract : The ability to position yourself and map the surroundings is an important aspect for both civilian and military applications. Global navigation satellite systems are very popular and are widely used for positioning. This kind of system is however quite easy to disturb and therefore lacks robustness. READ MORE

  4. 4. Blind Channel Equalization for Shortwave Digital Radio Communications

    University essay from Linköpings universitet/Reglerteknik

    Author : Tomas Busk; [2020]
    Keywords : Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Abstract : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

  5. 5. Accelerate Business Value in Manufacturing with Advanced Analytics

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Axel Lundholm; [2019]
    Keywords : Technology and Engineering;

    Abstract : Recent developments in smart manufacturing enable convergence between the digital and physical worlds of modern manufacturing facilities. This evolution is, however, far from trivial and thorough research and investigation needs to be conducted regarding dynamic connectivity of assets and implementation of data driven analytics, which provides deeper insight into the operational processes.
