    Sammanfattning : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. LÄS MER

  4. 3. Analysis of Passive Attitude Stabilisation and Deorbiting of Satellites in Low Earth Orbit

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik
