  1. 6. Livscykelanalys av grundläggning - En fallstudie av 11 projekt

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Marilena Iulia Cismaru; Tove Ahlgren; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Efter en lagändring som trädde i kraft 1 januari 2022 infördes krav på klimatdeklarationer vid uppförande av nya byggnader. Syftet med ändringen är att samla in data och statistik för att i framtiden kunna införa gränsvärden på klimatpåverkan. LÄS MER

  3. 7. Creating safe, lively and attractive street spaces in city centres : A case study of Nygatan and Järnagatan in Södertälje

    Master-uppsats, KTH/Urbana och regionala studier

    Författare :Bakhaya Jeanette; Felicia Norlin; [2023]
    Nyckelord :sustainability; safe; alive; attractive; street space; city centre; street; design; urban form; mobility; environment; social; enjoyment; movement; public places; pedestrian friendly; hållbarhet; trygg; levande; attraktiv; gaturum; stadskärna; gata; utformning; stadsform; mobilitet; miljö; socialt; njutning; rörelse; offentliga platser; gångvänligt;

    Sammanfattning : Throughout time, cities have been built in different ways and city structures can look different in different places in the world. The urban planning ideal has changed and small narrow alleys in the city have today been replaced by large roads adapted for cars. LÄS MER

  4. 8. Hybrid bridge deck of timber and corrugated steel plates

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Muze Lu; [2023]
    Nyckelord :;

    Sammanfattning : Over the years, hybrid structures composed of timber and steel have become a potential alternative to conventional solutions. Recently, corrugated steel plate (CSP) has become more and more popular in structures such as shear walls and roofs due to its favorable mechanical properties. LÄS MER

  5. 9. Starshades: Geoengineering Solutions and Technosignatures in Direct Imaging Phase Curves

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

    Författare :Claudia Skoglund; [2023]
    Nyckelord :Starshades; extraterrestrial intelligence; stellar evolution; technosignatures; phase curves; direct imaging; habitable zone.; Physics and Astronomy;

    Sammanfattning : The stellar luminosity increases as a star evolves which inevitably yields a higher temperature on planets in orbit around the star. It is reasonable to assume that intelligent civilizations would tackle this issue through installing artificial structures that can alter the radiation received by the planet. LÄS MER

  7. 10. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

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

    Författare :Kaibin Wen; [2023]
    Nyckelord :Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Sammanfattning : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. LÄS MER
