  1. 1. Graph Neural Networks for Events Detection in Football

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

    Author : Giovanni Castellano; [2023]
    Keywords : Machine Learning; Graph Neural Network; Recurrent Neural Network; Trajectory Data; Football; Events Detection; Maskininlärning; Graph Neural Network; Recurrent Neural Network; Bandata; fotboll; händelsedetektering;

    Abstract : Tracab’s optical tracking system allows to track the 2-dimensional trajectories of players and ball during a football game. Using this data it is possible to train machine learning models to identify events that happen during the match. READ MORE

  3. 2. Laboratory starlight simulator for future space-based heterodyne interferometry

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : William Karlsson; [2023]
    Keywords : Angular resolution; Astronomy; Coherence length; Digital delay lines; Fiber optical circuit; Heterodyne interferometry; Interference; Laboratory starlight simulator; NIR light Near-Infrared ; Optical path differences; Space exploration; Starlight; Testbed environment;

    Abstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE

  4. 3. FPGA Implementation of an Online Free-Space Optical Communications Test-Bed

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

    Author : Hamza Mahmoud; [2023]
    Keywords : Test-bed; FPGA design; PRBS; FSO; Optical communication; Testbädd; FPGA-design; PRBS; FSO; Optisk kommunikation;

    Abstract : Free Space Optical (FSO) satellite communications is proving to be a key enabling technology for global connectivity with the ability to provide connection across Europe with only 12 ground stations. For this, Deutsches Zentrum für Luft- und Raumfahrt (DLR) is working on implementing a robust communication system for FSO on a Xilinx RFSoC Field Programmable Gate Array (FPGA)( ZU28DR). READ MORE

  5. 4. A Platform for a Wheeler's Delayed-Choice Experiment in Optical Fiber

    University essay from Linköpings universitet/Informationskodning

    Author : Gustaf Åhlgren; [2022]
    Keywords : Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation;

    Abstract : Quantum mechanics has played a big role in the development of our understanding of the smallest things in the universe. It has provided descriptions for phenomena like single electrons or single photons, which are single particles of light. One of the most mysterious properties of quantum systems is the ability to behave as a particle or a wave. READ MORE

  6. 5. Design and Commissioning of Pulsed Wire Magnetic Measurement System for Insertion Device Characterization

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Mohammed Ebbeni; [2021]
