  1. 1. Shape depiction using Local Light Alignment : Evaluating the shape enhancement capabilities of the Local Light Alignment technique at multiple scales

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Edvard Ahlsén; [2023]
    Nyckelord :Shape depiction; Non-photorealistic rendering; Shading; Multiple scales; Formskildring; ickerealistisk rendering; skuggning; skalrymdsmetoder;

    Sammanfattning : Local Light Alignment is a new shading based technique in the field of shape depiction, a field which concerns itself with techniques to represent and enhance the three-dimensional (3D) shape of objects in two-dimensional (2D) visual media. The main idea of Local Light Alignment is to locally adjust the incoming direction of light to create contrast in a way that enhances the perception of shape and surface detail. LÄS MER

  3. 2. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

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

    Författare :WULLSCHLEGER LÉA; [2023]
    Nyckelord :Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Sammanfattning : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. LÄS MER

  4. 3. Svenska gymnasieelevers uppfattningar om storlek och avstånd i universum

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för utbildningsvetenskap

    Författare :Karolin Nilsson; [2023]
    Nyckelord :Astronomy; Misconceptions; Educational Research; Science Education; High School Students; Physics and Astronomy;

    Sammanfattning : This study aims to investigate how students in Swedish upper secondary school conceptualize sizes and distances of some astronomical objects, such as planets and stars, as well as the students’ general knowledge of the objects themselves. The study uses a constructivist framework and explores how well the students’ conceptions match the scientific facts and definitions, and what misconceptions and alternative conceptions they hold.

  5. 4. The tangled Warp of the Milky Way

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Viktor Hrannar Jónsson; [2023]
    Nyckelord :Galaxy: structure; Galaxy: kinematics and dynamics; Galaxy: disk; Galaxy: evolution; Physics and Astronomy;

    Sammanfattning : Context: The Milky Way disc, like the discs of many other spiral galaxies, has been shown to be warped. The growing astrometric data set for stars produced by the Gaia mission allows for more detailed studies of the stellar disc's warp. LÄS MER

  7. 5. Mobile Traffic Classification and Multi-Cell Base Station Control for Energy-Efficient 5G Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Cai Tianzhang; [2023]
    Nyckelord :;

    Sammanfattning : The global energy consumption of mobile networks is rapidly increasing due to the exponential growth of mobile network traffic. The advent of next-generation cellular technologies such as fifth-generation (5G) and beyond promises higher network throughput and lower latency but also demands higher power consumption for its denser base station (BS) deployment and more energy-intensive processors.
