  1. 1. Techno-economic analysis and simulation of low temperature district heating networks

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Ilia Iarkov; [2023]
    Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

  3. 2. Wound Treatment : An overview and initial investigation of wound care and bioactive materials

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Louise Ringholm; [2023]
    Nyckelord :Wound treatment; wound care; bioactive materials; calcium silicate;

    Sammanfattning : Wound care is a field with many treatment methods and products on the market. The healing period varies, some wounds become difficult to heal and chronic, in many cases a connection can be drawn to underlying diseases. Diabetes is a disease that could cause foot ulcers that are difficult to heal. LÄS MER

  4. 3. Utformning av hållbara byggnader : Balansen mellan utsläpp och isoleringsförmåga

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Hannah Marklund; Fanny Åsander; [2023]
    Nyckelord :;

    Sammanfattning : In Sweden, more buildings are being built today than ever before, while awareness of the consequences this has for the climate has increased. On January 1, 2022, a law came into effect to introduce climate declarations for new constructions. This is one step towards becoming a country that will have net zero emissions by 2045. LÄS MER

  5. 4. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/FREIA

    Författare :Karl-Fredrik Boholm Kylesten; [2023]
    Nyckelord :attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Sammanfattning : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. LÄS MER

  7. 5. Reducing cost and CO2 emissions in the gasoline to electric vehicle fleet transition

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Emil Grund Stålvinge; [2023]
    Nyckelord :electric car; electric conversion; bldc; li-ion; lion; lipo; li-po; volvo; elbil; elbilar; elkonvertering; bldc; li-ion; lion; lipo; li-po; volvo;

    Sammanfattning : If you buy a new electric car today it will take on average about ten years for you to start saving money compared to just continue driving your old gasoline car. It will also take about 4 years until you start saving carbon dioxide emissions, both of this is because of new production costs and emissions. LÄS MER
