1. A case study on Trucks’Crossmembers at Volvo Group
Master-uppsats, KTH/ProduktionsutvecklingSammanfattning : This thesis aims at investigating the crossmember business within the context of Volvo Trucks, with a focus on identifying standardization opportunities and optimizing the supply chain for improved efficiency and cost savings. The objectives of this study include mapping commonalities in design, raw material grade, surface finish, and thickness across different trucks and brands. LÄS MER
2. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications
Master-uppsats, KTH/Teknisk mekanikSammanfattning : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. LÄS MER
3. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : 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. När platserna inte räcker till : En kvalitativ studie om gatekeeping inom dansvärlden
Kandidat-uppsats, Södertörns högskola/SociologiSammanfattning : The aim of this study is to widen the sociological knowledge about how gatekeepers make selections, in contexts characterized by uncertainty. This is examined through the dance world as empirical case, based on the question “How do gatekeepers orientate themselves in the uncertainty that characterizes decision-making around which dance artists should be assigned dance residencies?”.

5. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction
Master-uppsats, KTH/Teknisk mekanikSammanfattning : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. LÄS MER
