  1. 6. Resonance Mitigation in the Attitude Control of a Flexible Large Solar Sail

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Jonas Linnros; [2023]
    Keywords : Resonance; Control theory; Mechanics; Solar sail; PID; Space; Resonans; Reglerteknik; Mekanik; Solsegel; PID; Rymd;

    Abstract : This project is about the design process of a resonancemitigating algorithm for a large solar sail. The solar sail isa structure made up by four long booms in a cross patternwith suspended sails between the edges of the booms. Thespacecraft in this report is controlled using smaller rotatingsails at each tip of the booms. READ MORE

  2. 7. Assessing the Extent of Diffuse Liver Disease: Quality Assurance of Magnetic Resonance Elastography (MRE)

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anna Åkvist; [2022]
    Keywords : ;

    Abstract : The mechanical properties of liver tissue such as stiffness are closely correlated with various diseases. Magnetic resonance elastography (MRE) aims at estimating these mechanical properties by imaging the waves induced by an external driver in the liver. READ MORE

  3. 8. Computational modelling of photosynthetic excitons coupled to a microcavity

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Ilmari Turunen; [2022]
    Keywords : Cavity QED; LH2; Chlorophyll; Exciton; Polariton; Transition dipole moment; Absorbance; Physics and Astronomy; Chemistry; Biology and Life Sciences;

    Abstract : Cavity quantum electrodynamics (QED) is a theory that is used for describing the interaction between matter and cavity modes. Not until relatively recently, cavity QED has been extended to the study of photosynthetic light-harvesting complexes (LHCs). READ MORE

  4. 9. NVH analysis and optimization of electric powertrain

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Anujit Dafle; [2022]
    Keywords : Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

    Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

  5. 10. Quantum Computing in Nuclear Physics

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Luca Bernecker; [2022]
    Keywords : quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

    Abstract : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. READ MORE
