1. 6. Application of Physics-Informed Neural Networks for Galaxy Dynamics

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Lucas Barbier; [2023]
   Nyckelord :;

   Sammanfattning : Developing efficient and accurate numerical methods to simulate dynamics of physical systems has been an everlasting challenge in computational physics. Physics-Informed Neural Networks (PINNs) are neural networks that encode laws of physics into their structure. LÄS MER

3. 7. Macrosegregation Prediction in Continuously Cast Steel Slabs

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Malek Al-Ameri; [2022]
   Nyckelord :;

   Sammanfattning : A prediction model [3] of macrosegregation in continuously cast steel slabs developed by Barber et al from Corus Teesside Technology Centre, UK as an extension of the work of Miyazawa and Schwerdtfeger [4] is presented in this thesis. Improvements have been made in the model to include the effect of many bulges between the supporting rolls induced by the ferrostatic pressure exerted on the solidifying shell by the liquid phase, which were approximated following a deflection of an elastic beam model.

4. 8. Extension of low voltage distribution by pure DC or mixed AC/DC parts for integration of solar PV and EV charging

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

   Författare :Sofie Jiang; [2022]
   Nyckelord :LVDC; LVAC; solar PV system; electric vehicle charging station; IKN-regulation; distribution system; RES integration; LVDC; LVAC; solceller; elfordon; laddstolpar; IKN-regelverk; distributionsnät; förnyelsebara energikällor;

   Sammanfattning : This work examines the local distribution system in two residential areas in two Swedish towns, Oxelösund and Karlskrona, and studies how integration of PV systems and electric vehicle (EV) charging stations (CS) will affect the present distribution system. The research questions focus on the economic feasibility of a LVDC system, how it compares to a traditional LVAC (low voltage alternating current) system from an economic and technical perspective, and the possibilities a LVDC system brings to other DC component applications.

5. 9. What would be the highestelectrical loads with -20°C inStockholm in 2022 ? : A study of the sensitivity of electrical loads to outdoor temperature in Stockholm region.

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

   Författare :Magali Mellon; [2022]
   Nyckelord :Data-driven approach; Electrical load forecasting; Temperature sensitivity; Linear Regression; Time series analysis; SARIMAX;

   Sammanfattning :  In the last 10 years, no significant increase in the peak electricity consumption of the region of Stockholm has been observed, despite new customers being connected to the grid. But, as urbanization continues and with electrification being a decisive step of decarbonization pathways, more growth is expected in the future. LÄS MER

7. 10. Comparative life cycle assessment of two desiccant wheel dehumidifiers with industrial application

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

   Författare :Astrid Ortis; [2022]
   Nyckelord :Desiccant wheel dehumidifier; adsorption dehumidification; life cycle assessment LCA ; EU Taxonomy; Rotorsorptionsavfuktare; luftavfuktning; livscykelanalys LCA ; EU taxonomi;

   Sammanfattning : Humans spend around 80 percent of their lifetime indoors. The humidity level plays an essential part in indoor climate, both in non-industrial applications, such as thermal comfort, and industrial ones. Dehumidification is a technology in the field of thermal comfort and indoor climate to control humidity levels. LÄS MER
