  1. 16. Acceleratorers inverkan på betong avseende bearbetbarhet, pumpbarhet och hållfasthetstillväxt

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Roger Valden; Temesgen Nehemiah; [2020]
    Nyckelord :Konsistens; Hållfasthetsutveckling Accelerator; betong; cement; murbruk; bascement; byggcement; snabbhårdnande cement; flödestid; flytsättmått; flödestest; mald granulerad masugnsslagg; superplasticerare; självkompakterande betong; tryckhållfasthet; kompressionstest;

    Sammanfattning : The following thesis is a comparison study which was performed in cooperation with Sika Sverige AB. The project was to examine concrete’s behaviour while being subjected to different accelerators which is used to speed up the hardening process in young concrete. Sika provided the materials and the instructions for the tests that were made. LÄS MER

  3. 17. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Simon Wozny; [2020]
    Nyckelord :topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

    Sammanfattning : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. LÄS MER

  4. 18. PWAMP - Combine technology for faster loading and improved user experience

    M1-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :Jesper Nyhlén; [2020]
    Nyckelord :PWAMP; Google AMP; Gatsby; Progressive Web App; Performance;

    Sammanfattning : Progressive Web Applications are becoming more advanced and have increased user activity year after year, especially on mobile platforms. But still the standard of performance does not in most cases meet what we expect in relation to the time it takes to load these. LÄS MER

  5. 19. Source code quality in connection to self-admitted technical debt

    Magister-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Alina Hrynko; [2020]
    Nyckelord :Self-admitted technical debt; technical debt; bug; issue; SonarQube; code quality;

    Sammanfattning : The importance of software code quality is increasing rapidly. With more code being written every day, its maintenance and support are becoming harder and more expensive. New automatic code review tools are developed to reach quality goals. One of these tools is SonarQube. LÄS MER

  7. 20. The Inclusion of Stratification in Wind Analysis; A New Linearized Code

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Roland Nyberg; [2020]
    Nyckelord :Wind Energy; Stratification; Speed-up effect; Monin-Obukhov similarity theory; Vindenergy; Stratifikation; Speed-up effekt; Monin-Obukhov teori;

    Sammanfattning : Wind energy is rapidly growing around the world as non-renewable energy sources are being phased out. To maximize the energy production, it is crucial to construct new wind turbines at locations where the average wind speed is high. An accurate wind assessment of a new potential site is thus essential in the development of new wind farms. LÄS MER
