  1. 21. Mission Concept for a Satellite Mission to Test Special Relativity

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Volkan Anadol; [2016]
    Keywords : BOOST; Special Relativity; Kennedy Thorndike; Eclipse duration; Ground visibility; Downlink feasibility; 3-axis stabilization; Spin stabilized satellite; Solar array estimation; Battery size estimation.;

    Abstract : In 1905 Albert Einstein developed the theory of Special Relativity. This theory describes the relation between space and time and revolutionized the understanding of the universe. While the concept is generally accepted new experimental setups are constantly being developed to challenge the theory, but so far no contradictions have been found. READ MORE

  3. 22. Energy saving using traffic adaptive base station operation (cell DTX) in heterogeneous cellular networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Tukue Gebremariam Gebregergis; [2015]
    Keywords : ;

    Abstract : Nowadays, mobile broadband data traffic is growing exponentially and will continue to grow for the coming years. Accordingly, the operational cost of a mobile network will increase significantly due to the fact that a large number of base stations will be deployed to support the high traffic demand. READ MORE
