  1. 11. Geometric comparison of 3D city models for daylight simulations

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johannes Lande Nyborg; [2022]
    Keywords : Geography; Physical Geography; Ecosystem Analysis; 3D city model; 3D building models; daylight access; daylight simulations; obstruction angle; free and open-source software; sustainable urban development; Geomatics; Earth and Environmental Sciences;

    Abstract : As cities keep densifying, essential resources such as daylight access become increasingly restricted. Therefore, prioritizing energy efficiency and enhancing the energy performance of our buildings is required for obtaining a sustainable urban environment. READ MORE

  2. 12. Analysis, Implementation and Evaluation of Direction Finding Algorithms using GPU Computing

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Regina Andersdotter; [2022]
    Keywords : GPU; GPU Computing; Direction Finding; GPU Suitability; CUDA; Multiple Signal Classification; Weighted Subspace Fitting; Correlative Interferometer; runtime; angle resolution; block size;

    Abstract : Direction Finding (DF) algorithms are used by the Swedish Defence Research Agency (FOI) in the context of electronic warfare against radio. Parallelizing these algorithms using a Graphics Processing Unit (GPU) might improve performance, and thereby increase military support capabilities. READ MORE

  3. 13. Probing for plumes in observations of Europa in transit over Jupiter : A data analysis using Hubble Space Telescope images

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emil Larsson; [2022]
    Keywords : Europa; Jupiter; Hubble Space Telescope; Water; Plumes; Europa; Jupiter; Hubbleteleskopet; Vatten; Plymer;

    Abstract : In 2016 Sparks et al. [14] reported evidence of water plumes above the Galilean moon Europa. Their method consisted of creating a model image of Europa transiting Jupiter and analytically comparing it with an actual far-ultraviolet observation from the Hubble Space Telescope. In 2020 Giono et al. READ MORE

  4. 14. Designing k-Space Filters to Improve Spatiotemporal Resolution with Sector-Wise Golden Angle (SWIG)

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Jonas Ström Seez; [2022]
    Keywords : Cardiovascular Magnetic Resonance Imaging CMR ; k-Space Filter; Sector Wise Golden-angle SWIG ; Kardiovaskulär Magnetisk Resonans Tomografi CMR ; k-rumsfilter; Sektorsvis Gyllene Vinkel SWIG ;

    Abstract : The aim of this thesis is to design and evaluate k-space weighting filters for simultaneously improving the spatial and temporal resolution of cardiovascular MRI, with the ultimate goal of improving the accuracy of quantitative flow measurements, which are important for diagnosis and follow-up of heart dysfunction. Two different k-space filters were implemented and evaluated retrospectively to already acquired data. READ MORE

  5. 15. Optimizing a servo drive using Field Oriented Control

    University essay from Uppsala universitet/Solcellsteknik

    Author : Lukas Land; [2021]
    Keywords : antenna; servo; foc; pmsm; vector engine; field oriented control; electrical motor; servo; fältorienterad kontroll; elmotor;

    Abstract : An optimization of a servo system for a satellite antenna system wasperformed. A brushless DC motor with an angle encoder was used, whoseangular velocity had to be controlled with great precision. Specializedhardware was used to implement field oriented control to directlycontrol the torque and magnetic flux of the motor. READ MORE
