1. 1. Club Head Tracking : Visualizing the Golf Swing with Machine Learning

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Fredrik Herbai; [2023]
   Nyckelord :Golf; Machine learning; Neural network; XGBoost; Interpolation; Deep learning; Data collection; Data augmentation;

   Sammanfattning : During the broadcast of a golf tournament, a way to show the audience what a player's swing looks like would be to draw a trace following the movement of the club head. A computer vision model can be trained to identify the position of the club head in an image, but due to the high speed at which professional players swing their clubs coupled with the low frame rate of a typical broadcast camera, the club head is not discernible whatsoever in most frames.

3. 2. Sound Propagation Through Walls

   Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Alexander Berglund; Fredrik Herbai; Jonas Wedén; [2021]
   Nyckelord :acoustics; wave propagation; infrasound; finite difference methods; SBP-SAT; one dimension; analytical calculation; numerical simulation;

   Sammanfattning : Infrasound is undetectable by the human ear and excessive exposure may be a substantial health risk. Low frequency sound propagates through walls with minimal attenuation, making it difficult to avoid. This study interprets the results from both analytical calculations and simulations of pressure waves propagating through a wall in one dimension. LÄS MER
