  1. 1. Development of a new SBRT dose planning strategy for thoracic tumours in RayStation

    University essay from Umeå universitet/Radiofysik

    Author : Olof Westman; [2023]
    Keywords : radiotherapy sbrt lung robust; radioterapi;

    Abstract : Umeå University Hospital has acquired a new treatment planning system, RayStation, for radiotherapy. It has a different set of dose calculation algorithms that require new planning strategies for stereotactic lung cancer treatments. READ MORE

  3. 2. Analysis of Flow Prolongation Using Graph Neural Network in FIFO Multiplexing System

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

    Author : Weiran Wang; [2023]
    Keywords : Network Calculus; Flow Prolongation; Graph Neural Network; Fast Gradient Sign Method; Delay Bound; Nätverkskalkyl; Flödesförlängning; Graph Neural Network; Fast Gradient Sign Method; Fördröjningsgräns;

    Abstract : Network Calculus views a network system as a queuing framework and provides a series of mathematical functions for finding an upper bound of an end-to-end delay. It is crucial for the design of networks and applications with a hard delay guarantee, such as the emerging Time Sensitive Network. READ MORE

  4. 3. 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

  5. 4. Assessing Offshore Wind System Integration: Comparative Analysis of Floating Photovoltaics, Oscillating Surge Wave Converters, and Battery Energy Storage Systems

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Wilhelm Niilekselä; Douglas Hansson; [2023]
    Keywords : Technology and Engineering;

    Abstract : The high penetration of wind power is increasing the intermittency and power variability into the existing power grid. This is forcing industries to look for optimal configurations in order to improve their systems performance and minimize these effects from the power production method. READ MORE

  6. 5. Estimation of Voltage Drop in Power Circuits using Machine Learning Algorithms : Investigating potential applications of machine learning methods in power circuits design

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

    Author : Dimitrios Koutlis; [2023]
