  1. 1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

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

    Författare :Robin Drevet; [2024]
    Nyckelord :space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

    Sammanfattning : 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.

  3. 2. Teknoekonomisk utvärdering och klimatpåverkan av konventionella värme- och kylsystem i kontorsfastigheter

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Gusten Lindé; [2023]
    Nyckelord :Kylmaskin; värmeåtervinning; fjärrvärme; fjärrkyla; bergvärme; frikyla; klimatpåverkan; LCA; LCC;

    Sammanfattning : Vid bestämmelse av vilket värme- och kylsystem som ska användas i fastigheter så finns det flertalet aspekter som går att ta hänsyn till. Tidigare har det varit högt fokus på energi och ekonomi, men med ökat fokus på hållbarhet och miljön både globalt och i Sverige har det blivit allt mer viktigt att hitta robusta lösningar som presterar inom samtliga av dessa områden.

    Nyckelord :Knowledge Management; Ontology; Graph database; Graph theory; Virtual Factory; Knowledge-Driven Optimization;

    Sammanfattning : Ontology-based technologies like Semantic Web and Knowledge Graphs are promising for knowledge management in manufacturing industries. In the literature there are abundant of publications related to using ontologies to represent and capture knowledge in manufacturing. LÄS MER

  5. 4. A Preliminary Framework For The Selection Of Materials & Manufacturing Processes For Lunar Surface Systems Assuming Integration To A Space Circular Economy

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Gabriel Sanchez; [2022]
    Nyckelord :Embodied Energy; Space Habitat; Re-Purposability; Material Value; Sustainability; Space Recycling; Design for Recycling; Design to Repurpose;

    Sammanfattning :  In-situ resource utilization and in-situ manufacturing are being actively pursued as ways to enhance the development of human activities in space. However, the re-purpose of space systems through processes like recycling, re-manufacturing, and re-use, has not received the attention it deserves given its potential to reduce the waste generated by human activities in space, improve the sustainability of space habitats, and reduce the environmental impact on Earth of human activities in space.
