  1. 1. Using Neural Radiance Fields and Gaussian Splatting for 3D reconstruction of aircraft inspections

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Roos Eline Bottema; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The rapid evolution of machine learning techniques has revolutionized computer vision, particularly with the introduction of Neural Radiance Fields (NeRF) and the optimization of 3D Gaussians for rendering novel scene views. These methods, such as NeRF and Gaussian Splatting, have demonstrated success in synthetic data scenarios with consistent lighting and well-captured scenes. LÄS MER

  3. 2. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
    Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER

  4. 3. Hunting Snakes in the Eagle's Nest : Skydd av flygbas med drönare

    Kandidat-uppsats,

    Författare :Anders Olofsson; Magnus Olofsson; [2023]
    Nyckelord :Obemannat; UAS; RPAS; Drönare; Flygbas; Övervakning; Autonom; Etik;

    Sammanfattning : ´The use of unmanned aerial vehicles has not escaped anyone, not least in the Ukraine war. Sweden has operated UAV systems for almost 30 years, but on a relatively small scale. The technology is used to a greater extent by some armed forces. LÄS MER

  5. 4. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Gusten Zandler Andersson; [2023]
    Nyckelord :Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Sammanfattning : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. LÄS MER

  7. 5. Detecting flight patterns using deep learning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Victor Carlsson; [2023]
    Nyckelord :machine learning; AI; pattern detection; CNN; LSTM; transfer learning; ADS-B; flight pattern; trajectory classification;

    Sammanfattning : With more aircraft in the air than ever before, there is a need for automating the surveillance of the airspace. It is widely known that aircraft with different intentions fly in different flight patterns. Support systems for finding different flight patterns are therefore needed. LÄS MER
