  1. 1. Simulation-based discrimination of Crab pulsar models with XL-Calibur

    Master-uppsats, KTH/Fysik

    Författare :Dennis Åkerström; [2024]
    Nyckelord :Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

    Sammanfattning : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. LÄS MER

  3. 2. Estimating stellar limb darkening using exoplanet transits

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

    Författare :Sora Ishida; [2023]
    Nyckelord :Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

    Sammanfattning : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. LÄS MER

  4. 3. Impact of Central Nodes in Information Propagation over Graphs

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Oskar Mellegård; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : There are many systems which can be represented as graphs, to say the least the networks in which we communicate with each other. Thorough understanding of graph structures enables better predictions of the dynamics in real life networks, such as the spreading of a disease in a community or failure propagation in a system.

  5. 4. Language Theoretic Properties of Graph Extension Languages : An Investigation of Graph Extension Grammars with Context Matching and Logic

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Yannick Stade; [2022]
    Nyckelord :graph language; formal language; theoretical computer science;

    Sammanfattning : Graph extension grammars provide a way to define graph languages. They consist of a regular tree grammar and an algebra. The regular tree grammar generates trees, so-called derivation trees. Those are evaluated by the algebra into a set of graphs. LÄS MER

  7. 5. Describing Finite Codimensional Polynomial Subalgebras Using Partial Derivatives

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Erik Leffler; [2022]
    Nyckelord :Algebra Polynomial Derivations alpha-Derivations SAGBI Basis; Mathematics and Statistics;

    Sammanfattning : In this text we continue the work of describing subalgebras of K[x] of finite codimension that was started in Describing subalgebras of K[x] using derivatives. In the referenced paper, the authors present how univariate subalgebras can be described by conditions based on evaluations in certain scalars, and proceed to develop a large theoretical framework to understand the nature of such conditions.
