1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

2. Research of appropriate luminance level of monitor screens in workplace
Kandidat-uppsats, Högskolan Dalarna/InformatikSammanfattning : MÅL: Huvudsyftet med den här studien är att undersöka hur naturligt ljus påverkar det mänskliga ögats preferens för skärmens ljusstyrka när man tittar på en datorskärm. METODER: Tre experiment genomförs för att mäta i vilken utsträckning solljus förändrar bakgrundsljuset i form av solstrålning. LÄS MER
3. Investigation of Antenna Radomes in Low Earth Orbits
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

4. Development of a Novel Method for Automotive On-board Transmitter EMC Immunity Testing
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : As the automotive industry advances through technology integration, components are designed to operate at increasingly higher frequencies. Consequently, there will be an increasing demand for automotive electromagnetic compatibility (EMC) testing. LÄS MER
5. Techno economic study of high PV penetration in Gambia in 2040
Master-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : Meeting electricity demand and power shortage remains as a challenge to the people of the Gambia. As the country is undergoing tremendous electricity accessibility expansion [1], to secure the environment for the future generation, it is necessary to consider renewable energy to be the major source of electricity production, to be specific, solar energy.
