  1. 1. Heavy vehicles: Load variation and scatter

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Patrik Hård; [2020]
    Keywords : Load variation; Pseudo-damage; Scatter; Wheel configuration; Belastning; Variation; Hjulkonfiguration; Pseudo-skada;

    Abstract : This master thesis studies accelerations recorded and stored onboard Scania trucks. From these accelerations, a general load (𝐹 = 𝑚∗ 𝑎) description is deduced. In the next step, an abstract number, ‘pseudo-damage’, representing the load’s fatigue damage potential is calculated. READ MORE

  3. 2. Observing phase changes in real time on ultrathin Iron oxide surfaces

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Harald Wallander; [2019]
    Keywords : CO oxidation; platinum; iron oxides; Physics and Astronomy;

    Abstract : Studying catalysts under such non-equilibrium conditions is a step towards approaching more realistic reaction conditions for working catalysts. Reactivity during phase changes of ultra-thin FeO2 films grown on Pt(111) are studied in situ with Ambient Pressure X-ray Photo Emission Spectroscopy and Quadrupole Mass Spectrometry, while running the CO oxidation reaction at 160°C and 0:6 mbar.
