   Nyckelord :Alpha-iron; Chromium carbide; Cr7C3; Fe; Theoretical investigation; Orthorhombic; X-ray diffraction pattern; XRD; VASP; VESTA; Body-centered-cubic; Ferrite; Density functional theory; DFT; Surface relaxation; Simulation; Calculation; Energy relaxation; Slab models; Coherency; Surface energy; Interfacial energy; Alfa-järn; Kromkarbid; Cr7C3; Fe; Teoretisk undersökning; Ortorombisk; Röntgendiffraktion; XRD; VASP; VESTA; Ytenergi; Koherent; Simulering; Beräkning; Järnkarbid; DFT; Täthetsfunktionalanalys;

   Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER

3. 2. Optimering av timmerplanslogistik : Minimering av transportavstånd för den nya timmerplanen på Sävar såg

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

   Författare :Linnea Asp; Elvira Carstedt; [2022]
   Nyckelord :sawmill; timber logistics; optimization; assignment problem; transportation distance; log yard layout; sågverk; timmerlogistik; optimering; tillordningsproblemet; transportavstånd; timmerplansdesign;

   Sammanfattning : An increase in demand for sawed wood products is the reason why Norra Timber has to expand their facility at Sävar Sawmill. During the expansion, a new log sorting will be implemented which can sort timber with different characteristics and qualities compared to the current log sorting. LÄS MER

4. 3. Black Hole Dynamics in Stellar Clusters

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Markus Strickert; [2022]
   Nyckelord :Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Sammanfattning : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

5. 4. Comfortable Vehicle Surfaces : A Master Thesis on the Comfort Experience of Interior Vehicle Surfaces

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Anna Mellqvist; Simon Vicini; [2022]
   Nyckelord :Comfort; Automotive Design; Industrial Design Engineering; User Experience;

   Sammanfattning : This thesis was conducted to explore and try to understand the area of comfort within cars with an emphasize on interior surfaces. Research within comfort has been focused on the consequences of moving mechanical parts and not on the user experience of the interior cabin design. LÄS MER

7. 5. Ageing of NCA/Graphite-Silicon Cells : Investigating the feasibility of accelerated ageing

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

   Författare :Gustav Giske; [2022]
   Nyckelord :;

   Sammanfattning : Reliable test data on cell ageing is important to have when deciding on which cell to use in a vehicle. Accelerated ageing could, if performed in a good way, increase the amount of information about the cell ageing in an early stage of a vehicle project, reducing the risk of costly battery replacements.
