  1. 1. Influential Factors and Key Actors Shaping Sustainability Assurance Opinions: A Case Study of a Big-4 Firm

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

    Författare :John Gerendas; Axel Tottie-Håkansson; [2024]
    Nyckelord :Sustainability assurance; CSRD; Comfort; Task-oriented language; Materiality construction;

    Sammanfattning : The rise in sustainability reporting has increased the demand for sustainability assurance, especially in the light of new legislation, requiring more companies to undergo third-party assurance. This thesis provides insights into the practical work of a sustainability assuror in the sustainability assurance process and how sustainability assurance opinions are formed as well as how materiality is constructed.

  3. 2. Defining dark jets at the particle level

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Gustav Lindberg; [2023]
    Nyckelord :Particle physics; Dark matter; QCD; Physics and Astronomy;

    Sammanfattning : One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. LÄS MER

  4. 3. Atomic Structure Calculations Using Configuration-Interaction And Many-Body Perturbation Theory For Spectral Modelling Of Neutron Star Mergers : Example Of Ce I - Iv

    L3-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Fredrik Plane; [2023]
    Nyckelord :Computational atomic physics; Atomic physics; Physics; Astronomy; Astrophysics; Neutron stars; Stars; Relativisitc atomic physics; Configuration-interaction; Perturbation theory; Many-body perturbation theory;

    Sammanfattning : The binary neutron star merger of 2017 and its corresponding electromagnetic signature resembling that of a kilonova has been one of the most groundbreaking astrophysical occurrences in the last decade. Indications of r-process nucleosynthesis in this event presents new opportunities for learning about the astrophysical origin of heavy elements. LÄS MER

  5. 4. On Secure Administrators for Group Messaging Protocols

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Balbas Gutierrez; [2021]
    Nyckelord :Secure Messaging – Group Messaging – Ratcheting – Group Key Agreement – Cryptographic Administrators – Group Administration;

    Sammanfattning : In the smartphone era, instant messaging is fully embedded in our daily life. Messaging protocols must preserve the confidentiality and authenticity of sent messages both in two-party conversations and in group chats, in which the list of group members may suffer modifications over time.

  7. 5. Investigation of Autoencoders for Jet Images in Particle Physics

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Partikel- och kärnfysik

    Författare :Jessica Lastow; [2021]
    Nyckelord :data compression; anomaly detection; jet image; autoencoder; dark matter; machine learning; ATLAS; hadron jet; particle physics; high energy physics; Physics and Astronomy;

    Sammanfattning : Dark matter is an invisible type of matter believed to make up 85 % of the matter in the universe, but it has not yet been identified by experiments. According to certain particle physics theories, possible signatures of dark matter are so-called dark jets. They are the dark matter equivalent to classic jets, i.e collimated streams of particles.
