  1. 1. Propagation of Nuclear Data Uncertainties for Reactor Physics Parameters in Fluorine-19-based Molten Salt Reactors

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Sigfrid Stjärnholm; [2023]
    Nyckelord :;

    Sammanfattning : It could be argued that a renaissance is taking place for the global interest in nuclear power - especially for the development of the next generation of reactor systems that aim at solving the problems with contemporary energy production with nuclear technology. One such proposed concept for Gen IV nuclear power is a Molten Salt Reactor (MSR), in which the nuclear fuel is in solution of a salt - often based on fluorine or chlorine. LÄS MER

  3. 2. Determining Protein Conformational Ensembles by Combining Machine Learning and SAXS

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Samuel Eriksson Lidbrink; [2023]
    Nyckelord :AlphaFold; AlphaFold2; SAXS; protein conformational ensembles; machine learning; protein conformations; reweighting; SAXS; AlphaFold; AlphaFold2; proteinkonformationsensembler; maskininlärning; proteinkonformationer; omviktning;

    Sammanfattning : In structural biology, immense effort has been put into discovering functionally relevant atomic resolution protein structures. Still, most experimental, computational and machine learning-based methods alone struggle to capture all the functionally relevant states of many proteins without very involved and system-specific techniques.

  4. 3. Thermal neutron counting and gamma-ray peak identification from fusion reactions, using a Sodern Genie-16 Neutron Generator

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Auden Ti; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This thesis work focuses on the categorisation of a Sodern Genie-16 Neutron Generator, at the Nuclear Applications Laboratory, Lund University. To that end, the goals of this work focuses on the re-development of the pre-existing infrastructure surrounding the Sodern Genie-16 Neutron Generator for the purposes of internally irradiating samples, and the subsequent categorisation of the new configuration for extraction of fast neutrons.

  5. 4. Accurate Abundances of Giant Stars in the Local disk: A manual analysis of IR APOGEE spectra

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Ivalu Barlach Christensen; [2020]
    Nyckelord :Galactic Chemical Evolution; Astrophysics; Astronomy; IR Spectroscopy; Milky Way; Abundance; Physics and Astronomy;

    Sammanfattning : Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. LÄS MER

  7. 5. Detailed chemical abundances of neutron-capture elements - from 523 local giant stars

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Rebecca Forsberg; [2019]
    Nyckelord :The Milky Way galaxy; Abundances; High-resolution spectroscopy; Neutron-capture elements; Physics and Astronomy;

    Sammanfattning : Purpose: The purpose of this work is to determine the abundances of neutron-capture elements in solar neighborhood giant stars. This enables constraints to be put on the the cosmic origin of these elements. LÄS MER
