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

    University essay from Lunds universitet/Fysiska institutionen

    Author : Klara Stefansson; [2024]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

  3. 2. Monitoring of Partial Discharges on Cable Terminations : An experimental approach to evaluate non-conventional online PD measurement techniques

    Author : Tony Sibo; [2023]
    Keywords : Monitoring; Partial discharges; Medium-voltage cable terminations; Sensor performance; Reliability evaluation; Infrared camera IR-camera ; Ultrasonic emission sensor AE-sensor ; Temperature and relative humidity sensor TRH-sensor ; High frequency current transformer HFCT ; Transient earth voltage antenna TEV-antenna ; Conventional VS non-conventional PD measurement techniques; Övervakning; Partiella urladdningar; Mellanspänningskabelslut; Evaluering av sensorprestanda; Utvärdering av systemets tillförlitlighet; Infraröd kamera; Ultraljudssensor; Temperatur- och relativ fuktighetssensor; Högfrekvent strömtransformator; Transient jordspänningsantenn; Konventionella vs icke-konventionella mättekniker;

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

    University essay from Uppsala universitet/Institutionen för elektroteknik

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

    Abstract : 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. READ MORE

  5. 4. CHILLER DIAGNOSTICS Machine learning approach Carrier

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Vilius Koegst; Tatiana Orlova; [2022]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

  6. 5. Investigations of the Transient Luminous Events with the small satellites, balloons and ground-based instruments

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Safura Mirzayeva; [2022]
    Keywords : TLE; sprite; jet; elve; halo; lightning; lighting detection; upper-atmospheric lightning; lightning location; nanosatellite; CubeSat;

    Abstract : The lightning is the natural source of electromagnetic radiation. It is an atmospheric electrical discharge.  However, since recent times, it was discovered that there are other types of lightning besides those that are visible to the naked eye. They are called TLEs (Transient Luminous Event) and take place above the clouds during thunderstorms. READ MORE
