  1. 1. Development of a Rule Based Decision Support System for Pilots : Using Network Analysis, Label Propagation and Association Rule Mining

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Joel Henneberg; [2023]
    Nyckelord :;

    Sammanfattning : Maneuvering a fighter jet is not easy, and new methods for minimizing the risk of pilots experiencing information overload are constantly under development. Saab is currently looking into the possibilities of creating a decision support system (DSS) for pilots in situations where multiple independent system failures occur simultaneously. LÄS MER

  3. 2. Rocket Jet Impinging on a Surface

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Javier Capel Jorquera; [2022]
    Nyckelord :Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

    Sammanfattning : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. LÄS MER

  4. 3. Analysis of High and Low Rossby Wave Phase Speed Events Over Northern Mid-Latitudes

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

    Författare :Emma Rosengren; [2022]
    Nyckelord :Rossby waves; phase speed; atmospheric blocking; storm track; windstorms; Rossbyvågor; fashastighet; atmosfärisk blockering; lågtrycksbana; vindstormar;

    Sammanfattning : The large-scale, mid-latitude circulation in the upper troposphere is dominated by Rossby waves. The jet stream flows along the wave structure and surface cyclones can be found ahead of the troughs of the waves, propagating eastward. LÄS MER

  5. 4. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Daiki Makii; [2020]
    Nyckelord :Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

    Sammanfattning : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.

  7. 5. Probability of Positive Identification with an IFF E-scan System

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Tora Lutnaes; [2018]
    Nyckelord :;

    Sammanfattning : Both military and civil aircrafts depend on a built-in identification system called SSR on a daily basis. IFF is the military adaption of the system for use by fighter jets in order to separate friendly aircrafts from foes but also to coexist with commercial aircrafts. LÄS MER
