  1. 11. 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

  3. 12. Periodic Inhalation of Carbon Monoxide Prior to Repeated Sprint Training – a Nuanced Way for Improving Repeated Sprint Ability

    University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för fysisk aktivitet och hälsa

    Author : Christoffer Sundqvist; [2022]
    Keywords : Endurance; Cycling; high-intensity interval training; Repeated sprint ability; Repeated sprint exercise; Carbon monoxide.;

    Abstract : Background: Repeated sprint training in hypoxia has shown to be superior to training in normoxia. However, both natural and simulated altitude training are strategies that are not always accessible and expensive due to traveling or the need for advanced equipment. READ MORE

  4. 13. Conceptual Design of an Ekranoplan UAV

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

    Author : Sheng-An Yu; [2022]
    Keywords : Ekranoplan; Unmanned ground effect vehicle UGEV ; vertical take-off and landing VTOL ; aircraft design; Ekranoplan; Obemannad markeffektfarkost UGEV ; Vertikal Start och Landning VTOL ; Flygplansdesign;

    Abstract : Unmanned aerial system (UAS) has developed into an important platform of high-altitude photography, which can be applied in animal studies, pollution forensics and geographic monitoring. This thesis work aims to design a unmanned ground effect vehicle (UGEV) in order to provide a much better and flexible solution to future applications. READ MORE

  5. 14. Pixel correspondences for SLAM using sidescan sonar with canonical representations

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

    Author : Weiqi Xu; [2022]
    Keywords : ;

    Abstract : Acoustic instruments play an important role in autonomous underwater vehicles (AUVs). Sidescan sonar (SSS) detects a wider range, provides photo-realistic images in high resolution, and has lower price than the multibeam echo sounder (MBES). READ MORE

  6. 15. Studies of the PMWE : Polar Mesosphere Winter Echoes

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Abstract : This Master thesis examines a phenomenon that occurs in the upper polar atmosphere, namely, Polar Mesospheric Winter Echoes, or PMWEs. PMWEs are radar echoes observed by Very High Frequency Mesosphere Stratosphere Troposphere (VHF MST) radar, from altitudes of 60 to 76 km at 7 to 15 UT, in the winter months from the middle of September to the beginning of May.
