  1. 1. A method for developing stress-strain relationships using Nanoindentations

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Ludvig Lindsjö; Fanny Linander; [2021]
    Nyckelord :Nanoindentation; Material Science; Steel; Solid Mechanics; Technology and Engineering;

    Sammanfattning : This thesis is a material science research collaboration between the Division ofProduction and Materials Engineering at Lund Faculty of Engineering and theComputer-Aided Engineerings group at BorgWarner, Landskrona. The objectiveof the thesis is to explore the convertion of nanoindentation load-depth curves intotensile stress-strain curves, and to provide BorgWarner Landskrona with nanoin-dentation data on materials used in their standard production.

  2. 2. Investigation into the Removal of the By-product NDMA (N-Nitrosodimethylamine) from Ozonation Process in Wastewater Treatment

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Zehao Li; [2021]
    Nyckelord :Water resources engineering; Ozonation; NDMA; Wastewater; pharmaceutical; Diclofenac; Ibuprofen; Naproxen; Technology and Engineering;

    Sammanfattning : In people’s modern life, daily usage of artificial compounds such as active pharmaceuticals ingredients (API) is usual. These compounds are likely to end up as micropollutants in the municipal wastewater. Municipal wastewater is the major source of pharmaceuticals in the aquatic environment. LÄS MER

  3. 3. Squaring VEGAS -- Multidimensional Integration Using 2D Correlations

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik

    Författare :Philip Siemund; [2021]
    Nyckelord :statistics; numerical integration; Monte Carlo integration; VEGAS; Physics and Astronomy;

    Sammanfattning : Multidimensional integrals are used in many areas of physics; electrodynamics, quantum mechanics and statistical physics, to name a few. Many integrals can not be solved analytically, but can instead be approximated numerically. VEGAS is a Monte Carlo integration algorithm, which specializes it in approximating multidimensional integrals. LÄS MER

  4. 4. Heat dissipation due to microvibrations in low temperature experiments

    Master-uppsats, KTH/Fysik

    Författare :Julien Witwicky; [2021]
    Nyckelord :Spatial cryogenics; Micro-vibrations; Heat dissipation.; Rymdkryogenik; Mikrovibrationer; Värmeavledning.;

    Sammanfattning : Ultra-sensitive photodetectors on-board space missions need very low temperatures to keep a good resolution. Cryo-coolers, such as pulse-tubes, help maintaining these conditions within a cryostat. In return however, they generate micro-vibrations. LÄS MER

  5. 5. Validating results from the Molten Salt Reactor Experiment by use of turbulent CFD simulations : A study of a modified U-tube shell-and-tube primary heat exchanger and radiator with molten salts

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Malcolm Akner; [2021]

    Sammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A. LÄS MER
