  1. 11. Investigation of Antenna Radomes in Low Earth Orbits

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Mathias Manohar Gren; [2023]
    Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Sammanfattning : 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.

  3. 12. Shoplifting in Japan and Sweden - A comparative analysis of social structures and sanctions in the 21st century

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Författare :Henrik Queckfeldt; [2023]
    Nyckelord :Comparative Law; Criminal law; Law; Shoplifting; Restorative justice; Informal Social Control; Japan; Sweden; Law and Political Science;

    Sammanfattning : 概要 本稿は、読者に2つの司法制度の包括的な概観を提供し、その後、いくつかの追加的な側面を検討する。分析の構成により、読者は、社会が公式・非公式の統制という観点からどのように機能しているかを含め、法制度がどのように構築されているかを確認することができる。本稿はまた、さまざまな制裁がどのように実施され、それが個人と社会に与える影響についても探求している。個々の章では詳細な分析を行わず、必要に応じて十分な説明を行うようにしている。万引きを犯罪の例として挙げているのは、明確な比較が可能だからである。本論文では、両国の修復的司法を幅広く検証し、正式な刑事司法制度への影響を軽減するための潜在的な方策を検討している。最後に、包括的な分析を行い、それぞれの国について法的改善のための提言を行う。..

  4. 13. Coordinate Mark Out Using Intersecting Line Lasers

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jonas Carlsson; Jeremy Gallant; [2023]
    Nyckelord :Mark out; Laser; Mechatronics; Floor Layout; Three object triangulation; Utsättning; Laser; Mekatronik; Golvutsättning; Trippelobjektstriangulering;

    Sammanfattning : In the entertainment industry, where temporary structures are erected in a new venue every day, floor markings play an important role during the set up. Today, mark out is commonly done using tape measures - a very tedious and time consuming process. LÄS MER

  5. 14. Exploratory study of additively manufactured heat exchangers for aerospace applications

    Master-uppsats,

    Författare :Siddharth Nadukkandy; [2023]
    Nyckelord :;

    Sammanfattning : Thermal management is a crucial part in the aviation industry. It is also essential that the components involved in aviation be light weight. One of the vital components of thermal management is heat exchangers. It has been observed that the optimization of the heat exchanger is approaching its saturation with traditional manufacturing.

  7. 15. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER
