  2. 2. Satellite Front-End Equipment Based on Consumer Off-The-Shelf Single-Board Computers

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Nils Thorben Weber; [2018]
    Nyckelord :;

    Sammanfattning : This Master thesis project consists of the exploration and potentially the design and implementation of an Front-End Equipment (FEE) device based on the Beaglebone Black or similar single-board computers. During development and testing of a satellite system, FEE serves to adapt telemetry and telecommand data streams between a satellite and the ground- control system. LÄS MER

  3. 3. The Effects of Different Policies Affecting the Composition of the District Heating in Sweden

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Emma Hammarsten; Peter Röhr; [2013-10-23]
    Nyckelord :;

    Sammanfattning : This thesis gives an insight in the Swedish district heating sector and its choice between two different ways of producing heat; either by using only heat boilers (OHB) or by combined heat and power (CHP). This choice is researched through different policy-instruments such as emission taxes and the EU ETS. LÄS MER
