  1. 1. The Kiruna town move : Unearthing the possibilities for full-scale fire tests

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Henrik Pettersson; Adam Thörn; [2021]
    Nyckelord :Full-scale fire tests; Kiruna town move; SFPE roadmap; Fire tests; Kiruna s housing-stock; Fullskaliga brandförsök; Kiruna stadsflytt; Brandförsök; Kirunas Byggnadsbestånd;

    Sammanfattning : The work with this thesis started during the last semester at the Fire Protection Engineering program at Luleå University of Technology. Kiruna has relied on the iron ore resources of Luossavaara and Kiirunavaara since the creation of the town. The iron ore stretches underneath the current city center. LÄS MER

  2. 2. A comparison of binaural recordings performed in six different room configurations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Denice Perkhed; [2021]
    Nyckelord :Binaural recordings; absorbtion coefficient; reverberation time; anechoic chamber; listening test; Psychoacoustics; Technology and Engineering;

    Sammanfattning : Children in Swedish preschools are exposed to high noise levels that can cause hearing damage or voice related problems among both teachers and students, this since they have to raise their voice in order to make themselves heard in a noisy environment. Because of this it is of interest to be able to predict the sound environment in preschools. LÄS MER

  3. 3. Modified train wheel wear calculation for fast calculation

    Master-uppsats, KTH/Spårfordon

    Författare :Shaoyao Chen; [2021]
    Nyckelord :Precise contact point detection; Material Flexibility; Multiple contact points detection; Winkler theory; wear calculation; fast calculation; Exakt detektion av kontaktpunkter; materialflexibilitet; detektering av flera kontaktpunkter; Winkler-teori; förslitningsberäkning; snabb beräkning;

    Sammanfattning : In this thesis, a modified wear calculation method is developed to calculate the train wheel wear, which can give less precise but faster results compared to the classic wear calculation method. This modified method is developed based on the classic wear calculation method developed by Jendel, which uses Hertz theory and Kalker’s simplified theory to calculate the contact variables and uses Achard theory to calculate the wear volume in an iterative manner.

  4. 4. Machine-Learning for Lattice Models in and out of Equilibrium

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Johannes Sandberg; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Machine-learning methods have in recent years seen a great deal of use in condensed matter physics. In this thesis we apply such methods, specifically machine-learning with artificial neural networks, to the equilibrium and non-equilibrium description of the Hubbard and Hubbard-Holstein models.

  5. 5. Predictive modelling applied to estimate demand on new EV charging stations in the UK

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Daniel Fernández Marcos; [2021]
    Nyckelord :;

    Sammanfattning : The arrival of the electric vehicle is being faster than estimated. This growth requires a charging infrastructure that can cover the energy needs of electric mobility. To this end, it is necessary that the charging points be installed in the most suitable places to satisfy the coming demand. LÄS MER
