  1. 21. Total body perfusion imaging with 15O-water PET

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Anna Åhlström; [2023]
    Nyckelord :;

    Sammanfattning : Background Positron emission tomography scanners can be used together with the PET tracer 15O-water to image perfusion in the body. It has mainly been used to image perfusion in the brain and heart. The new total-body PET scanners have a larger axial field-of-view, making imaging of the whole body possible without moving the patient. LÄS MER

  3. 22. Dynamic Analysis of Portal Frame Bridges for High-Speed Trains : A Parametric Study

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Antonio Dib; Ramayana Salgado; [2023]
    Nyckelord :;

    Sammanfattning : A high-speed railway network is important for Sweden’s development. However, anincreasing train speed brings new challenges in bridge design due to higher bridgeaccelerations. LÄS MER

  4. 23. Assessing the Eco-efficiency of Swedish Crop Farms and the Role of Subsidies : a Directional Distance Function Approach

    Master-uppsats, SLU/Dept. of Economics

    Författare :Therese Ratilla; [2023]
    Nyckelord :Swedish crop farmers; CAP subsidies; FADN; stochastic frontier analysis; multi-output; one-step approach;

    Sammanfattning : The agriculture sector’s contribution to global greenhouse gas (GHG) emissions and its increasing vulnerability to the effects of climate change warrants assessments considering not only on-farm productivity but also the industry’s environmental sustainability. Utilizing the concept of eco-efficiency, this study analyzes the environmental performance of Swedish crop farms by incorporating farm-level GHG emissions as an undesirable output in the production function.

  5. 24. Mechanical and thermal buckling analysis of laminated composite plates

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Aswin Paremmal; Roopak Kuruthukulangara Varghese; [2023]
    Nyckelord :composite material; Mechanical Buckling; Buckling analysis;

    Sammanfattning : Composite laminated structures have many application fields such as aerospace, civil, marine, bio medical, transportation, and mechanical engineering because of their convenience in handling, and very good mechanical properties. Buckling behavior of laminated composite plates subjected to plane loads is indeed an important consideration in the primary design of aircraft and launch vehicle components. LÄS MER

  7. 25. En överlevnadsstudie av återfallsbrottslighet i Sverige 2010-2020

    Kandidat-uppsats, Stockholms universitet/Statistiska institutionen

    Författare :Martin Jonasson; Martin Lilja; [2023]
    Nyckelord :Survival analysis; Recidivism; Kaplan-Meier; Lognormal distribution; Cox proportional hazard model; Överlevnadsanalys; Återfall i brott; Kaplan-Meier; Lognormalfördelning; Cox proportionella hasardmodell;

    Sammanfattning : Återfallsbrottslighet är ett väl beforskat ämne inom såväl kriminologisk som statistik forskning. Däremot är underlaget begränsat och dåligt uppdaterat på svenska material. Denna studie har med överlevnadsanalys undersökt tid till återfall i Sverige över tidsperioden 2010 till 2020. LÄS MER
