  1. 1. Investigation of the magnetic fields of a young Sun-like star ∏1 UMa

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Lawen Ahmedi; [2020]
    Keywords : Magnetic field; star; young Sun; polarisation; Stokes vector;

    Abstract : In astronomy, the Sun has an important role. It keeps the solar-system together and is thesource for life, heat, light and energy to Earth. As any other star or planet, the Sun has amagnetic field. The magnetic field of the Sun has a great impact on the Sun itself as well asits surrounding. READ MORE

  2. 2. The verification and validation of a probabilistic risk analysis method for road tunnels

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Kim Genberg; Karin Sandin; [2020]
    Keywords : Tunnels; fire; evacuation; probabilistic risk analysis; QRA; verification and validation; Technology and Engineering;

    Abstract : In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled.
