  1. 1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Johannes Lövhall; [2024]
    Nyckelord :Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

    Sammanfattning : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.

  3. 2. Parameteridentifikation för matematisk modell beskrivande tumörcellers och makrofagers interaktioner

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Jonatan Bertolozzi; Regina Gustavsson; Karl Olsson-Lalor; Ellinor Svenningsson; [2023-11-28]
    Nyckelord :;

    Sammanfattning : Det finns sedan tidigare en mängd matematiska modeller som beskriver tumörcellers tillväxt och interaktioner med makrofager i kroppen. I projektet studerades en av dessa vilken beskriver tillväxtförloppet av malignt melanom i möss. Modellen innehåller ett antal parametrar varav några är oidentifierade. LÄS MER

  5. 4. System Identification of a Fixed-Wing UAV Using a Prediction Error Method

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Trulsa Eriksson; [2023]
    Nyckelord :System identification; Fixed-wing UAV; Modelling; Parameter estimation;

    Sammanfattning : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle.
