  1. 21. Accelerating longitudinal spinfluctuation theory for iron at high temperature using a machine learning method

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Marian Arale Brännvall; [2020]
    Keywords : Machine learning; longitudinal spin fluctuations; kernel ridge regression;

    Abstract : In the development of materials, the understanding of their properties is crucial. For magnetic materials, magnetism is an apparent property that needs to be accounted for. There are multiple factors explaining the phenomenon of magnetism, one being the effect of vibrations of the atoms on longitudinal spin fluctuations. READ MORE

  3. 22. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    University essay from KTH/Materialvetenskap

    Author : Hedda Pousette; [2019]
    Keywords : Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Abstract : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. READ MORE

  4. 23. Reverse osmosis temperature control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Dennis Dalenius; [2019]
    Keywords : Technology and Engineering;

    Abstract : Baxter develops medical devices that take advantage of reverse osmosis to purify water that’s being used in dialysis fluids. Reverse osmosis is a commonly used water purification process that removes unwanted particles from the water. READ MORE

  5. 24. Performance Assessment of Electrical Motor for Electric Aircraft Propulsion Applications : Evaluation of the Permanent Magnet Motor and its Limitations in Aircraft Propulsion

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Mathias Beckman; Alex Christy Gerald Volden; [2019]
    Keywords : Electric Aircraft; Permanent Magnet Electrical Motor; Losses; Hybrid-Electric Propulsion System; Environment; Global Warming; Aircraft Emission;

    Abstract : This thesis project will evaluate which kind of electrical motor is best suited for aircraft propulsion and which parameters effect the efficiency. An economic analysis was conducted, comparing the fuel price (Jet A1) for a gas turbine and the electricity price for an electric motor of 1MW. READ MORE

  6. 25. Change in heating costs for different renovation alternatives of a million-housing program building

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

    Author : Robert Alexandersson; Stephan Tran; [2019]
    Keywords : ;

    Abstract : In 2014 the network for energy efficient multi-residential buildings, BeBo, finished a project called “Ett hus, fem möjligheter” (“One building, five opportunities”). The purpose was to provide insight into and a comparison of five different renovation alternatives for an existing building from the million-housing program, resulting in a decrease in energy use by at least half.
