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

    University essay from KTH/Fysik

    Author : Dennis Åkerström; [2024]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Measuring copper abundances in the Galactic Bulge

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Nikolei Höglinger; [2024]
    Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  3. 3. Quantum Optical Description of High-order Harmonic Generation

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isabel Moreno; [2024]
    Keywords : Physics and Astronomy;

    Abstract : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

  4. 4. Inland Waterways and Short Sea Shipping - a feasible alternative for truck transportation in Sweden? - A Case Study of Container Shipping Between Uddevalla and Gothenburg -

    University essay from Göteborgs universitet/Graduate School

    Author : Filip Matei; Philip Vollert Lundqvist; [2023-07-03]
    Keywords : Inland waterway transportation; short sea shipping; containerized goods; cost comparison; environmental comparison; barge;

    Abstract : Within the European Union, Inland Waterway Transportation accounts for the lowest share of goods transport, with only 5.8%. In Sweden, the share is even lower where Inland Waterway Transportation accounts for less than 1% of the goods transports. READ MORE

  5. 5. Profitability During a Sustainability Transformation - A Case Study of a Swedish Petroleum and Biofuel Company

    University essay from Göteborgs universitet/Företagsekonomiska institutionen

    Author : Michael Crona; Filip Linnér; [2023-02-27]
    Keywords : This report examines the financial profitability of a petroleum and biofuel company during their sustainability transformation. The case company is Preem AB; the largest fuel company in Sweden. The study finds that debt-to-equity ratios tend to increase with investments in more sustainable solutions. This could propose a higher financial risk to the firm. The report also proposes and discuss the use of metrics for CO2- emission that are easier to understand than just the weight of the gas emitted. Preem does not seem to benefit from being part of the European Union’s Emissions Trading System ETS ; since their green investments are focused on reducing emissions in the use phase of their products; not in the production phase; which is what the ETS measures and rewards. The case study is based on an interview with a director at Preem to get an insight to the green investments. Data for financial- and environmental performance are collected from official reports published by Preem.;
