  1. 1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Klara Stefansson; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. LÄS MER

    Sammanfattning : The transmission of electric power over long distances has historically posed challenges. However, the advent of high-voltage engineering has not only addressed distance barriers and power losses in electricity transmission and distribution, but it has also significantly improved the efficiency and transmission capacity of power grids.

  4. 3. Detektion av lateraliserad avvikande aktivitet i elektroencefalografi av minnesinkodning via auditivt stimulus

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Fremja Ekre; Josefine Frid; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The aim of this study was to evaluate two methods of detecting a difference in activity between the two hemispheres of the brain when presented with stimulus during memory encoding. The difference intended to be detected was based on the lateralization of brain processing of sensory input, which was triggered by an auditory stimulus in one ear at a time. LÄS MER

  5. 4. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Farsad Mansori; [2022]
    Nyckelord :Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

    Sammanfattning : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. LÄS MER

  7. 5. CHILLER DIAGNOSTICS Machine learning approach Carrier

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Vilius Koegst; Tatiana Orlova; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Chillers are large and complex machines that are used for temperature regulation in large buildings and plants. An undetected fault in the machine can lead to extended downtime and cause both great financial losses and increased environmental impact. LÄS MER
