1. 1. RENOVATION USING PREFABRICATED FAÇADE ELEMENTS

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

   Författare :Aleksandra Milkova; Mohamed Soliman; [2024]
   Nyckelord :Keywords: Energy use; Reduce energy; EU; IVL; LKF; TES façade; Multi-active façade; Alingsås façade; Million Programme; Moisture risk analysis; Attachment; Thermal performance; WUFI; AUTOCAD; HEAT2; Technology and Engineering;

   Sammanfattning : The building sector uses about 40% of the total global energy use. Sweden aims to reach its new goal to reduce the energy use in their residential sector as well as commercial sector by 20%, which should be reached by year 2020 and 50% by year 2050. LÄS MER

3. 2. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Nyckelord :Carbon Capture and Storage; CCS; AMP DMSO; Gas Chromatography; amine absorption; analysis method development; Chemical Engineering; Chemistry;

   Sammanfattning : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. LÄS MER

4. 3. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Simon Weideskog; [2024]
   Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

   Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

5. 4. Profitability During a Sustainability Transformation - A Case Study of a Swedish Petroleum and Biofuel Company

   Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

   Författare :Michael Crona; Filip Linnér; [2023-02-27]
   Nyckelord :This report examines the financial profitability of a petroleum and biofuel company during their sustainability transformation. The case company is Preem AB; the largest fuel company in Sweden. The study finds that debt-to-equity ratios tend to increase with investments in more sustainable solutions. This could propose a higher financial risk to the firm. The report also proposes and discuss the use of metrics for CO2- emission that are easier to understand than just the weight of the gas emitted. Preem does not seem to benefit from being part of the European Union’s Emissions Trading System ETS ; since their green investments are focused on reducing emissions in the use phase of their products; not in the production phase; which is what the ETS measures and rewards. The case study is based on an interview with a director at Preem to get an insight to the green investments. Data for financial- and environmental performance are collected from official reports published by Preem.;

7. 5. Development of a guide system for free neutron oscillation searches at the European Spallation Source

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

   Författare :Linnéa Björk; [2023]
   Nyckelord :ESS; neutrons; dark matter; antimatter; neutron guides; Physics and Astronomy;

   Sammanfattning : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.
