  1. 1. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity

    Master-uppsats, KTH/Fysik

    Författare :Atabak Fathe Jalali; [2024]
    Nyckelord :Theoretical physics; astrophysics; modified gravity; minimally modified gravity; gravitational collapse; VCDM; scalar collapse; apparent horizon; numerical relativity; Teoretisk fysik; astrofysik; modifierad gravitation; minimalt modifierad gravitation; gravitationskollaps; VCDM; skalär kollaps; uppenbar horisont; numerisk relativitet;

    Sammanfattning : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. LÄS MER

  2. 2. En skandinavisk allians?

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Elin Korp; [2023-02-06]
    Nyckelord :Arbetarklass; Attityder; Arbetarklassattityder; Covid-19 pandemin; Pandemiåtgärder; Skandinavien; Välfärdsstater; Working class; Attitudes; Working class attitudes; Covid-19 containment measures; Scandinavian Countries; Welfare states;

    Sammanfattning : The Covid-19 pandemic resulted in a societal crisis where different groups of society were hit to varying degrees. One group that faced more severe consequences than others were the working class due to their limited economic resources and small opportunities to work from home. LÄS MER

  3. 3. Long, Long Time : An Examination of Identity and Status Connected to Scenography in the Tv-Series The Last of Us (2023)

    Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Författare :Anton Jonsson; [2023]
    Nyckelord :Kvalitativ visuell analys; representation; The Last of Us; Bourdieu; kapital; post-apokalyps; zombie; scenografi; identitet; status; medborgarförslag; illustration; kollage; kampanj; ungdomar; inflytande; demokrati; Malmö Stad; framtidstro;

    Sammanfattning : This study examines cinematic storytelling by looking at screenshots from episode three of the tv-series The Last of Us (2023). The purpose is to illustrate how scenography in the chosen material can represent meaningful concepts about the main character's identity and statues. LÄS MER

  4. 4. Exploring GANs to generate attack-variations in IoT networks

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Gustaf Bennmarker; [2023]
    Nyckelord :;

    Sammanfattning : Data driven IDS development requires a vast amount of data to be effective against future attacks and a big problem is the lack of available data. This thesis explores the use of GANs (Generative adversarial networks) in generating attack data that can be used as apart of a training set for an IDS to improve the robustness against adversarial attacks.

  5. 5. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Vikramjeet Das; [2023]
    Nyckelord :rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Sammanfattning : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. LÄS MER
