6. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity
University essay from KTH/FysikAbstract : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. READ MORE

7. Mining infrequent group of motifs from multidimensional time series: A case study at Alfa Laval AB
University essay from Högskolan i Halmstad/Akademin för informationsteknologiAbstract : In collaboration with an industrial partner, Alfa Laval AB, this thesis discusses a novel approach for identifying operational modes, specifically a cleaning mode, in separator machines without the benefit of labelled data and with very limited operating knowledge. Understanding the operational modes is crucial for comprehending the machine’s behaviour and ensuring its optimal performance. READ MORE

8. The visibility of stellar transients in the Galactic Centre
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AstrofysikAbstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

9. Robust non-Abelian geometric phases on three-qubit spin codes
University essay from Uppsala universitet/MaterialteoriAbstract : Quantum holonomies are non-Abelian Geometric Phases predominantly observed in adiabatic, non-adiabatic, or measurement-based quantum evolutions. Their significance lies in their potential utility within quantum computing due to their robustness against noise throughout the parameter path. READ MORE

10. Study case: The water-cooling effect on floating photovoltaic plants performance
University essay from KTH/EnergiteknikAbstract : Floating solar technology is relatively new, and it comes with its own set of challenges and opportunities. This master thesis focuses on understanding how Floating Photovoltaic (FPV) projects perform compared to Ground-Based Photovoltaic (GPV) projects, in specific weather conditions. READ MORE
