  1. 21. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hamish Keay; [2023]
    Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

  2. 22. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

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

    Author : Kyle William Coble; [2023]
    Keywords : Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

    Abstract : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. READ MORE

  3. 23. Optimization-Based Path Planning For Indoor UAVs in an Autonomous Exploration Framework

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

    Author : Marco Cella; [2023]
    Keywords : Optimal Path Planning; B-Splines; Autonomous Exploration; Indoor UAV; Crisis and Disaster Management; Trajectory Estimation; SITL; Optimal Banplanering; B-Splines; Autonom Utforskning; Inomhus-UAV; Kris- och Katastrofhantering; Uppskattning av Banor; SITL;

    Abstract : Exploration is a fundamental problem in robotics that requires robots to navigate through unknown environments to autonomously gather information about their surroundings while executing collision-free paths. In this project, we propose a method for producing smooth paths during the exploration process in indoor environments using UAVs to improve battery efficiency and enhance the quality of pose estimation.

  4. 24. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Viktor Svensson; Robin Raymundsson; [2023]
    Keywords : Acoustic; defect; detection; harmonic; Akustisk; defekt; detektion; överton;

    Abstract : When aluminium profiles are manufactured, defects may arise, especially when theprofiles are manufactured through extrusion. During the extrusion process, thesedefects occur on parts of the extruded material because of contaminates that needto be found. READ MORE

  5. 25. Robust Graph SLAM in Challenging GNSS Environments Using Lidar Odometry

    University essay from Linköpings universitet/Reglerteknik

    Author : Jesper Sundström; Alfred Åström; [2023]
    Keywords : graphslam; graph slam; graph; slam; automatic; control; robust; DCS; RRR; lidar odometry; gnss;

    Abstract : Localization is a fundamental part of achieving fully autonomous vehicles. A localization system needs to constantly provide accurate information about the position of the vehicle and failure could lead to catastrophic consequences. READ MORE
