  1. 1. Multi-Data Approach for Subsurface Imaging: Combining Borehole and GPR- Data for Improved Analysis

    University essay from Umeå universitet/Institutionen för fysik

    Author : Pontus Yngvesson; [2023]
    Keywords : Geofysik; Geoteknik; GPR; Borrhål; Dataanalys; Markradar;

    Abstract : The investigation to understand the subsurface and its features has long been asubject of interest for various fields, including fields such as archaeology and infras-tructure projects. However, traditional excavation methods are often costly and time-consuming. READ MORE

  3. 2. Data Driven Modeling for Aerodynamic Coefficients

    University essay from KTH/Matematisk statistik

    Author : Erik Jonsäll; Emma Mattsson; [2023]
    Keywords : Master s thesis; System identification; Parameter estimation; Ordinary least squares; Machine learning; Aerodynamic coefficients; F18--HARV; Flight simulations.; Masteruppsats; Systemidentifiering; Parameteruppskattning; Minstakvadratmetoden; Maskininlärning; Aerodynamiska koefficienter; F18-HARV; Flygsimuleringar.;

    Abstract : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters. READ MORE

  4. 3. Dynamic Path Planning, Mapping, and Navigation for Autonomous GPR Survey Robots

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ketill Hjartarson; [2023]
    Keywords : Robotics; Autonomous navigation; SLAM; ROS; GPR;

    Abstract : To map the subsurface Ground Penetrating Radar (GPR) can be used in a non-invasive way. It is currently done manually by pushing a wheeled device on a handlebar. This thesis suggests an alternative method using an integrated autonomous solution. READ MORE

  5. 4. Autonomous Propulsion for a GPR-UGV

    University essay from Umeå universitet/Institutionen för fysik

    Author : Fredrik Wall Eskilsson; [2022]
    Keywords : robotics; gpr; autonomous; robot; ros; slam;

    Abstract : This thesis presents the research and development behind the integration of an autonomous propulsion system for a four-wheeled Ground Penetrating Radar (GPR) measurement unit, previously requiring manual operation. In order to ease the administration of the complex new system, Robot Operating System (ROS) 2 was used as middleware, where an implementation of Light Detection And Ranging (LiDAR) 3D-SLAM (Simultaneous Localization And Mapping) served to secure precise localization of the Unmanned Ground Vehicle (UGV) and mapping of its environment.

  6. 5. Enhancing GPR Measurements using Real Time Kinematics and LiDAR Mapping

    University essay from Umeå universitet/Institutionen för fysik

    Author : Christoffer Elebro; [2022]
    Keywords : GPS; GNSS; RTK; Lidar; 3D-mapping;

    Abstract : A Ground Penetrating Radar (GPR) is a non-invasive measurement tool to locate objects in the subsurface. The GPR transmits electromagnetic waves into the ground and records the waves reflected from surface interfaces of different materials. READ MORE
