  1. 6. Ray Tracing Algorithm for Dielectric Domes

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

    Author : Maria Pubill; [2023]
    Keywords : Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

  2. 7. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Adam Jacobsson Trönndal; [2023]
    Keywords : Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

    Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE

  3. 8. Improving Behavior Trees that Use Reinforcement Learning with Control Barrier Functions : Modular, Learned, and Converging Control through Constraining a Learning Agent to Uphold Previously Achieved Sub Goals

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

    Author : Jannik Wagner; [2023]
    Keywords : Behavior Trees; Reinforcement Learning; Control Barrier Functions; Robotics; Artificial Intelligence; Verhaltensbäume; Verstärkendes Lernen; Kontrollbarrierefunktionen; Robotik; Künstliche Intelligenz; Beteendeträd; Förstärkningsinlärning; Kontrollbarriärfunktioner; Robotik; Artificiell Intelligens;

    Abstract : This thesis investigates combining learning action nodes in behavior trees with control barrier functions based on the extended active constraint conditions of the nodes and whether the approach improves the performance, in terms of training time and policy quality, compared to a purely learning-based approach. Behavior trees combine several behaviors, called action nodes, into one behavior by switching between them based on the current state. READ MORE

  4. 9. Finite Control Set-Model Predictive control of Permanent Magnet Synchronous Motor

    Abstract : The electrification of the transportation sector has been the most important goal of the current century. In the last decade, there has been a surge in the production and sale of electric vehicles, necessitating substantial research and development in the industry. READ MORE

  5. 10. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

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

    Author : Qinglong He; [2022]
    Keywords : Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

    Abstract : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. READ MORE
