  1. 1. Effects of visualization using different convolution kernels in Julia

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Nils Forsberg; Axel Nilsson; [2023]
    Nyckelord :Convolution; Julia; visualization; streamlines; vorticity; interpolation; filter;

    Sammanfattning : Many real-world engineering problems require large amounts of data in order to accurately model and predict outcomes. However, this data is often noisy, sampled and discontinuous, making the data difficult to process and giving rise to incorrect models. LÄS MER

  3. 2. SOLAR WIND HEATING OBSERVED BY SOLAR ORBITER

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Karan Pal; [2023]
    Nyckelord :;

    Sammanfattning : In this project, we investigate the plasma heating associated with coherent structures, such as current sheets and vortices, in different solar wind conditions: slow solar wind, stream interaction regions, and heliospheric current sheets, observed by the Solar Or- biter mission. To unravel this mystery, we first use the Partial Variance of Increment method [1] to locate these coherent structures. LÄS MER

  4. 3. BLOOD FLOW DYNAMICS IN IDEALIZED MODEL OF LEFT ATRIUM USING FINITE ELEMENT ANALYSIS

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Marwin Haddad; Yonatan Noel Efrem; [2023]
    Nyckelord :finite element analysis; fluid mechanics; blood flow dynamics; cardiovascular anatomy;

    Sammanfattning : Cardiovascular diseases, including heart failure, are a global health concern, necessitating advancements in non-invasive diagnostic tools and treatments. Computational modeling offers an invaluable approach to simulate and understand the intricacies of cardiac flow dynamics. LÄS MER

  5. 4. Development of a Low Noise Drone Propeller Using CFD Simulations

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Axel Schulz; [2023]
    Nyckelord :Drone Propeller Low Noise Computational Fluid Dynamics CFD; Technology and Engineering;

    Sammanfattning : Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. LÄS MER

  7. 5. Extreme precipitation events in the Sichuan Basin and their connection to mesoscale disturbances

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Anna Dugoul; [2022-10-04]
    Nyckelord :;

    Sammanfattning : The Sichuan Basin (SB) is a region with frequent extreme precipitation during summer, principally as a result of its location and topography, with the most extreme events possibly leading to floodings and landslides. A better understanding of these extreme events’ characteristics and triggers could help to improve forecasting methods, while improving the knowledge about climate dynamics in the region is crucial for climate change studies.
