  1. 1. The megaliths of Bohuslän in a south Scandinavian context

    Master-uppsats,

    Författare :Roger Cederberg; [2022-11-15]
    Nyckelord :Neolithic; Southern Scandinavia; Dolmen; Passage grave; C14; Bohuslän;

    Sammanfattning : The transformation from a hunter/gatherer population to a farming society in southern Scandinavia is a process of only 300-400 years, primarily from around 4000 BC to around 3700 BC. Farming is then established in most of southern Scandinavia. LÄS MER

  2. 2. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Filip Hörberger; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density variations within the beam-path.

  3. 3. Explanatory Value of Risk Factors for Post-IPO Volatility

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Oscar Ribrant; Ludwig Åberg; [2022]
    Nyckelord :Initial Public Offering; Risk Factors; Volatility; Uncertainty;

    Sammanfattning : Since 2017, Swedish business magazine Affärsvärlden examines all Swedish IPOs and subsequently hand out risk flags divided upon 21 predetermined measures. These flags aim to highlight uncertainties connected to the maturity, suitability, IPO process and prospectus of respective companies. LÄS MER

  4. 4. Fast Simulations of Radio Neutrino Detectors : Using Generative Adversarial Networks and Artificial Neural Networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Anton Holmberg; [2022]
    Nyckelord :Askaryan emission; Radio detection of neutrinos; in-ice propagation; neutrino; Generative adversarial networks; GAN; WGAN; Neural networks; NN; surrogate model; IceCube; deep learning; generative model;

    Sammanfattning : Neutrino astronomy is expanding into the ultra-high energy (>1017eV) frontier with the use of in-ice detection of Askaryan radio emission from neutrino-induced particle showers. There are already pilot arrays for validating the technology and the next few years will see the planning and construction of IceCube-Gen2, an upgrade to the current neutrino telescope IceCube.

  5. 5. Comparison of different approaches for modelling the beam-target reactivity in fusion plasmas

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Marcus Petersson; [2022]
    Nyckelord :JET; Fusion; Fusion Diagnostics; Computational Physics; Modelling; NBI; Beam-Target Reactivity;

    Sammanfattning : Fusion research has been an ongoing research endeavour for many decades and it has the potential of providing an important part in the future of energy production. An important part of this process is to understand and control the various heating systems of the reactor where one of the most important systems being the Neutral Beam Injector (NBI) which injects particles at high velocities into the plasma.
