  1. 1. Theoretical investigation of Co-dependence in magnetic high-entropy alloys

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johan-Michael Kurak; [2023]
    Nyckelord :;

    Sammanfattning : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. LÄS MER

    Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER

  4. 3. Accelerating longitudinal spinfluctuation theory for iron at high temperature using a machine learning method

    Master-uppsats, Linköpings universitet/Teoretisk Fysik

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

    Sammanfattning : 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. LÄS MER

  5. 4. Fourier transform of BCC andFCC lattices for MRI applications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Leo Svenningsson; [2015]
    Nyckelord :Fourier transform; MRI; BCC; FCC;

    Sammanfattning : The Cartesian Cubic lattice is known to be sub optimal when consideringband-limited signals but is still used as standard in three-dimensional medical magneticresonance imaging. The optimal sampling lattices are the body-centered cubic latticeand the face-centered cubic lattice. LÄS MER

  7. 5. Efficient and Accurate Volume Rendering on Face-Centered and Body-Centered Cubic Grids

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Karl-Oskar Smed; [2015]
    Nyckelord :rendering; bcc; fcc;

    Sammanfattning : The body centered cubic grid (BCC) and face centered cubic grid (FCC) offer improved sampling properties when compared to the cartesian grid. Despite this there is little software and hardware support for volume rendering of data stored in one of these grids. LÄS MER
