  1. 21. Adaptive detection of anomalies in fuel system of Saab 39 Gripen using machine learning : Investigating methods to improve anomaly detection of selected signals in the fuel system of Gripen E.

    Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Författare :Ahlgren Bergström Olof; [2022]
    Nyckelord :Machine Learning; Adaptive anomaly detection; Modeling; Fuel system; Saab Gripen;

    Sammanfattning : The process of flying fighter jets naturally comes with tough environments and manoeu-vres where temperatures, pressures and forces all have a large impact on the aircraft. Part degeneration and general wear and tear greatly affects functionalities of the aircraft, and it is of importance to carefully monitor the well being of an aircraft in order to avoid catastrophic accidents.

  3. 22. CFD study of the different inlet configurations and airflows in a room with IJV

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Christos Stiapis; [2022]
    Nyckelord :Ventilation; CFD; Impinging Jet Ventilation;

    Sammanfattning : A method of providing ventilation using impinging jets (IJV) utilizes stratification while delivering air at a high velocity. As a result of this attribute and the simplicity of its terminal construction, IJV offers an advantage over the well-known Displacement Ventilation (DV) system. LÄS MER

  4. 23. Flying through cometary jets with the Rosetta spacecraft

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Brais Gesto Herrera; [2022]
    Nyckelord :;

    Sammanfattning : The Rosetta spacecraft orbited around comet 67P/Churyumov-Gerasimenko from 2014 to 2016. During this time, several thousands of cometary jets occurred and were photographed by the onboard cameras. LÄS MER

  5. 24. Autoencoder Compression in High Energy Physics

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Författare :Sten Åstrand; [2022]
    Nyckelord :High energy physics; LHC; ATLAS; hadron jet; machine learning; autoencoder; dimensionality reduction; artificial intelligence; data compression; Physics and Astronomy;

    Sammanfattning : Situated in Geneva, Switzerland, the Large Hadron Collider is largest particle accelerator in the world, and as such, its operation carries with it some of the greatest technical challenges ever faced. Among them are the huge demands put on data storage capacity by experiments in particle physics, both in terms of rate and volume of data. LÄS MER

  7. 25. Turbulence Intensity During Low-Level Jets in the Baltic Sea

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Thomasson August; [2021]
    Nyckelord :Low-Level Jet; Turbulence intensity; Shear sheltering; LiDAR; Baltic Sea; Low-Level Jet; Turbulensintesitet; Shear sheltering; LiDAR; Östersjön;

    Sammanfattning : Low-level jets (LLJs) are local wind speed maximums in the atmospheric boundary layer. In the Baltic Sea, LLJs are frequently occurring in spring and summer. It is an important phenomena to consider for wind energy parks, and changes in turbulence during the jets can effect the efficiency of said parks. LÄS MER
