  1. 11. Designing a communication controller for a wireless sensor network : Practical considerations and comparisons

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Frej Larssen; Axel Karlsson; [2023]
    Keywords : Wireless sensor networks; IoT; LTE-M; Comparison; Trådlösa sensornätverk; IoT; LTE-M; Jämförelse;

    Abstract : As the use of Internet of Things (IoT) devices increases, so does the number of available hardware platforms. Today there exists a broad range of hardware components that could be used to develop an IoT product and selecting the right ones is a difficult task. READ MORE

  3. 12. Probability Based Path Planning of Unmanned Ground Vehicles for Autonomous Surveillance : Through World Decomposition and Modelling of Target Distribution

    University essay from Linköpings universitet/Reglerteknik

    Author : Per Liljeström; [2022]
    Keywords : Probability based path planning; Unmanned ground vehicles; UGV; Autonomous surveillance; Cell decomposition; Spatial partitioning; Target distribution modeling; Decay function; Last-seen function; Stochastic processes; Markov chain; Markov process; Markov planner;

    Abstract : The interest in autonomous surveillance has increased due to advances in autonomous systems and sensor theory. This thesis is a preliminary study of the cooperation between UGVs and stationary sensors when monitoring a dedicated area. The primary focus is the path planning of a UGV for different initial intrusion alarms. Cell decomposition, i. READ MORE

  4. 13. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Tim Wiik; [2022]
    Keywords : Sensor fusion; UAV; UGV; NIR-LED; Extended kalman filter; Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; GNSS-denied Scenario;

    Abstract : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.

  5. 14. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Edvin Nilsagård; Rebecka Knutsson; [2022]
    Keywords : ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Abstract : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. READ MORE

  6. 15. Localization of Combat Aircraft at High Altitude using Visual Odometry

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jenny Nilsson Boij; [2022]
    Keywords : Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

    Abstract : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. READ MORE
