  1. 1. Biochar and district heating : The path to negative emissions

    Kandidat-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Amanda Widlund; Thomas Norström; William Isaksson; Andreas Andersson; [2023]
    Nyckelord :biochar; pyrolysis; climate impact; carbon sink; district heating;

    Sammanfattning : Uppsala Kommun is developing a new city district called Sydöstra staden (SÖS) as an innovative and transformative city district. A technical supply system that aligns with the district’s goals is pyrolysis. Pyrolysis is a process where biomass is heated without the supply of oxygen. LÄS MER

  3. 2. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Elias Önerud; [2023]
    Nyckelord :Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Sammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER

  4. 3. A Comparative Lifecycle Impact Analysis: Assessing Global Warming Potential of Newly Manufactured and Reused Bricks for Building Construction in Sweden

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

    Författare :Set Nyi Aung; Srikanth Panda; [2023]
    Nyckelord :Newly manufactured Bricks; Reused Bricks; Lifecycle Impact Assessment; GaBi ts; openLCA; Technology and Engineering;

    Sammanfattning : The aim of the study is to compare the environmental performance in terms of Global Warming Potential (GWP), for reused bricks and newly manufactured bricks used in Swedish Construction Industry. The objective of the study was to compile and conduct Life Cycle Assessment (LCA), in terms of GWP, of newly manufactured and reused clay façade bricks used in Sweden. LÄS MER

  5. 4. Performance Optimization of Ice Sheet Simulation Models : Examining ways to speed up simulations, enabling for upscaling with more data

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Fredrika Brink; [2023]
    Nyckelord :performance optimization; Python libraries; ice sheet simulations; Numba; Joblib; upscaling; parallelization;

    Sammanfattning : This study aims to examine how simulation models can be performance optimized in Python. Optimized in the sense of executing faster and enabling upscaling with more data. To meet this aim, two models simulating the Greenland ice sheet are studied. The simulation of ice sheets is an important part of glaciology and climate change research. LÄS MER

  7. 5. Mapping Several NIS2 Directive Articles to Technical Specifications for the Healthcare Sector in Sweden

    Master-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Iyad Al Khatib; [2023]
    Nyckelord :;

    Sammanfattning : Compliance with legal instruments is vital for the survival of any organization or company in the public and private sectors. Non-compliance may result in criminal and financial penalties that can have grave effects on the indicted institution. LÄS MER
