  1. 1. Fermi-LAT gamma-ray and multi-wavelength SED analysis and modelling of PKS 0426-380 : A thesis analysing the behaviour and properties of the blazar PKS 0426-380

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Nathanael Löfström; [2022]
    Nyckelord :active galactic nucleus; black hole; AGN; Fermi-LAT; JetSeT;

    Sammanfattning : An analysis is made on the Flat Spectrum Radio Quasar PKS 0426-380 using two sets of data. The first set of data is the Fermi-LAT data collected over the time 54682.66 − 59317.66 in Modified Julian Date within the energy range of 100 MeV to 500 GeV. LÄS MER

  3. 2. Mapping the Singularity : A Diagrammatic Analysis of Kurzweil’s Singularity Argument and Some Objections

    Kandidat-uppsats, Uppsala universitet/Filosofiska institutionen

    Författare :Oskar Areskog; [2021]
    Nyckelord :Argument Diagram; Ray Kurzweil; The Singularity is Near; Singularity; Argument Mapping; Argument Tree; Critical Thinking; Argumentation Theory;

    Sammanfattning : Constructing and understanding arguments is often difficult but key to both philosophyand other parts of the everyday life. Some methods to ease this task has been developed.One of the methods developed within informal reasoning is argument diagramming, amethod to structure and visualize arguments. LÄS MER

  5. 4. The impact of metallic cranial implants on proton-beam radiotherapy treatment plans for near implant located tumours : A phantom study on the physical effects and agreement between simulated treatment plans and the resulting treatment for near implant located cranial tumours

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Adam Sjögren; [2018]
    Nyckelord :Proton-based Radiotherapy; Cranial implants; Titanium implants; Cancer treatment; metal streak artifacts.;

    Sammanfattning : Within the field of radiotherapy treatments of tumour diseases, the hunt for more accurate and effective treatment methods is a continuous process. For some years ion-beam based radiotherapy, especially the proton-beam based applications, has increased in popularity and availability. LÄS MER

  7. 5. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Jonatan Fast; [2017]
    Nyckelord :Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Sammanfattning : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.
