  1. 1. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)

    University essay from KTH/Fysik

    Author : Oscar Wistemar; [2023]
    Keywords : Gamma-Ray Bursts; Astrophysics; Engineering Physics; Gamma-Blixtar; Astrofysik; Teknisk Fysik;

    Abstract : Gamma-ray bursts (GRBs) are some of the most energetic events in the universe. Shocks occurring below the photosphere are likely radiation mediated shocks (RMSs) and are suspected to shape the spectra. Due to computational costs of simulating RMSs, models had not been fitted to data and a faster model was needed. READ MORE

  3. 2. Superluminous magnons in Nickel Oxide

    University essay from Uppsala universitet/Materialteori

    Author : Jannes van Poppelen; [2023]
    Keywords : ;

    Abstract : Recent experiments have shown that the magnon velocity over nanoscale distancesin certain antiferromagnetic materials, with NiO in particular, far exceeds the previous theoretical maximum. Antiferromagnetic insulators are excellent candidatesfor spintronic nanodevices due to their exceptionally low energy dissipation, whichcould benefit the future speed at which information is stored.

  4. 3. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    University essay from KTH/Hållfasthetslära

    Author : Abhiroop Chatterjee; [2023]
    Keywords : ;

    Abstract : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. READ MORE

  5. 4. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Duncan Jones; [2023]
    Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur.

  6. 5. Quantum signatures in the work fluctuation-dissipation relation protocol

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Jian Li; [2023]
    Keywords : Quantum entanglement; fluctuation; coherence; quantum information; quantum thermodynamics; Physics and Astronomy;

    Abstract : Quantum thermodynamics deals with the behavior of thermal machines that operate in the quantum regime, where coherences and entanglement can have a significant impact. However, detecting such quantum effects in thermal machines can be challenging, as they are primarily manifested as fluctuations. READ MORE
