  1. 11. Radar and sea clutter simulation with Unity 3D game engine

    M1-uppsats, Linköpings universitet/Programvara och system

    Författare :Mikael Johnsson; Linus Bergman; [2023]
    Nyckelord :radar simulation; sea clutter simulation; game engine; Unity; ray tracing; compute shader; graphics programming; GPU; radarsimulering; sjöklottersimulering; spelmotor; Unity; strålspårning; compute shader; grafisk programmering; GPU;

    Sammanfattning : Game engines are well known for their use in the gaming industry but are starting to have an impact in other areas as well. Architecture, automotive, and the defence industry are today using these engines to visualise and, to some extent, test their products. LÄS MER

  3. 12. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)

    Master-uppsats, KTH/Fysik

    Författare :Oscar Wistemar; [2023]
    Nyckelord :Gamma-Ray Bursts; Astrophysics; Engineering Physics; Gamma-Blixtar; Astrofysik; Teknisk Fysik;

    Sammanfattning : Gamma-ray bursts (GRBs) are some of the most energetic events in the universe. Shocks occurring below the photosphere are likely radiation mediated shocks (RMSs) and are suspected to shape the spectra. Due to computational costs of simulating RMSs, models had not been fitted to data and a faster model was needed. LÄS MER

  4. 13. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anton Rolseth; [2023]
    Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER

  5. 14. Mapping the pig value chain in the Dominican Republic with emphasis on the risk of transmission of African swine fever

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Andrea Hentz; [2023]
    Nyckelord :African swine fever; Domestic pig; Value chain mapping; Pig production; Biosecurity; Disease risk;

    Sammanfattning : As in many other parts of the world, pigs provide an important source of food and income in the Dominican Republic (DR). However, the pig production in the country faces great challenges since African swine fever (ASF) was reintroduced in 2021, after being absent for over 40 years. LÄS MER

  7. 15. Effect of Trace Elements on the Particle Size of Magnesium Silicide in Aluminium Extrusion : The Use of Thermo-Calc and DICTRA in order to Produce Aluminium more Efficiently

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Gustav Boustedt; Johan Alexander Valentin Nygren; Gustav Strandgård; [2023]
    Nyckelord :Thermo-Calc; DICTRA; simulations; EN AW 6082; extrusion; particle precipitation; Mg2Si; sustainable; trace elements; aluminium;

    Sammanfattning : This project is a feasibility study for Hydro Extrusion Sweden AB, a company that produces extruded aluminium profiles. The main purpose of this project was to analyse the difference of Mg2Si particle sizes in aluminium alloys when varying parameters, such as cooling rate and composition, in aluminium extrusion, particularly the EN AW 6082 alloy.
