  1. 16. Domain Transfer for End-to-end Reinforcement Learning

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Anton Olsson; Felix Rosberg; [2020]
    Nyckelord :Reinforcement Learning; Domain Transfer; Deep Deterministic Policy Gradient; Reinforcement Learning in Real-time;

    Sammanfattning : In this master thesis project a LiDAR-based, depth image-based and semantic segmentation image-based reinforcement learning agent is investigated and compared forlearning in simulation and performing in real-time. The project utilize the Deep Deterministic Policy Gradient architecture for learning continuous actions and was designed to control a RC car. LÄS MER

  3. 17. Dimples in corrugated channels to improve efficiency in plate heat exchangers

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Gustav Karlsson; [2020]
    Nyckelord :Dimples; Plate Heat Exchangers; Heat Transfer Enhancement; CFD; Large Eddy Simulation; Reynolds Averaged Navier Stokes Simulation; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : The development of new heat exchanger patterns is ever changing. Companies are constantly pushing innovation to satisfy costumer needs in terms of thermal efficiency, reliability and serviceability. In this thesis, the implementation of dimples in the corrugated pattern of a plate heat exchanger is investigated to increase the thermal efficiency. LÄS MER

  4. 18. Stars Eating Planets

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :John Wimarsson; [2020]
    Nyckelord :Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

    Sammanfattning : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. LÄS MER

  5. 19. Investigation on the energy consumption of wireless RPM sensor

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Yang Song; [2020]
    Nyckelord :Embedded sensors; low-energy;

    Sammanfattning : Energy-saving wireless sensors are increasingly used in the industry. Users can remotely monitor the status of the measured device and do not need to frequently replace the battery of the device. In this thesis, we studied a low-cost energy-independent wireless speed sensor system that can power itself by the rotation of the host. LÄS MER

  7. 20. Investigation of heat transfer and mass transfer parameters in a convection oven for model foods

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Chandana Mysore Somashekar; [2020]
    Nyckelord :Food engineering; Livsmedelsteknik; Technology and Engineering;

    Sammanfattning : Forced air convection systems are the most preferred design of choice in many of the industrial-scale convection ovens. In this study, experimental investigation on convective heat transfer and mass transfer within a forced air convection oven was performed at different oven temperatures (100℃, 110℃ and 120℃) and at flow velocity (2 m/s, 3 m/s and 4 m/s) using potato slices (10*10*60 mm) as model food.
