  1. 1. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Filip Tuvenvall; [2023]
    Keywords : Machine Learning; Laser Ultrasonics; Material Properties; Steel; Hardness of Steel;

    Abstract : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. READ MORE

  3. 2. Radar odometry based on Fuzzy-NDT scan registration

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Johan Henriksson; [2021]
    Keywords : ;

    Abstract : Visual and lidar-based odometry for mobile robots has been thoroughlyinvestigated and performs very well in good weather conditions. However,both are sensitive to bad weather conditions with atmospheric disturbancessuch as rain and snow. Recently Radar sensors specialized for mobilerobot use have become available. READ MORE

  4. 3. A research study for inspection and detection on conductive materials

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Kawan Kandili; [2020]
    Keywords : Impedance Measurements; Non conductive thickness measurement; Crack Detection; EC NDT;

    Abstract : This master thesis is about to investigate what opportunities we have with a impedance varying probe on different material under test. This report begins with a theory part with the focus on; electromagnetic principles, material characterizations and the principle behind the measurement setup. READ MORE

  5. 4. Classication framework formonitoring calibration ofautonomous waist-actuated minevehicles

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Per Landström; John Sandström; [2020]
    Keywords : SVM; NDT; machine learning; scan matching; hinge angle sensor; calibration detection;

    Abstract : For autonomous mine vehicles that perform the ”load-haul-dump” (LHD) cycle to operate properly, calibration of the sensors they rely on is crucial. The LHD cycle refers to a vehicle that loads material, hauls the material along a route and dumps it in an extraction point. READ MORE

  6. 5. Sensor Position Optimization for Multiple LiDARs in Autonomous Vehicles

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

    Author : Rohit Ravindranath Kini; [2020]
    Keywords : LiDAR Position Optimization; Point Cloud Density; Genetic Algorithm; PCL; CARLA.; LiDAR Position Optimization; Point Cloud Density; Genetisk Algoritm; PCL; CARLA.;

    Abstract : 3D ranging sensor LiDAR, is an extensively used sensor in the autonomous vehicle industry, but LiDAR placement problem is not studied extensively. This thesis work proposes a framework in an open- source autonomous driving simulator (CARLA) that aims to solve LiDAR placement problem, based on the tasks that LiDAR is intended for in most of the autonomous vehicles.
