  1. 1. Beam Steering Antenna Based on Continuous Transverse Stub Array and Flat Risley Prism Metasurface Lens

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carl Henriksson; Jonathan Fransson; [2023]
    Nyckelord :;

    Sammanfattning : Satellite communication is an integral part of society in this day and era. Due tobandwidth limitations communication frequencies have moved into higher frequencybandwidths. With the advancements in communication comes the demand for more efficientantennas due to the high attenuation of millimeter wavelength frequencies. LÄS MER

  3. 2. Compiler Testing by Random Source Code Generation

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Victor Löfgren; [2023]
    Nyckelord :Compiler testing; random testing; fuzz testing; random program generation; automated testing;

    Sammanfattning : Most software projects today are written using programming languages. Compilers in turn translate programs written in these higher level languages into machine code, executable on actual hardware. Ensuring that these compilers function correctly is therefore paramount. LÄS MER

  4. 3. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Filip Hörberger; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density variations within the beam-path.

  5. 4. Development of a computational method for determining gamma energy escape from calorimeters at CLAB

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Amela Mehic; [2022]
    Nyckelord :Nuclear physics; Calorimeter; SNF; MCNP; Dose rate; CLAB; Gamma energy; Fuel assembly; Form function; Attenuation coefficient; Gamma spectroscopy;

    Sammanfattning : Swedish Nuclear Fuel and Waste Management Company- SKB has conducted measurement campaigns at the Swedish central interim storage facility for spent nuclear fuel- CLAB over the years, extending from year 2003 to 2019 where the gamma energy escape was acquired. At CLAB the spent nuclear fuel assembly is inserted into the calorimeter; device intended to measure temperature increase due to decay heat from the fuel assembly. LÄS MER

  7. 5. Impact of MR training data on the quality of synthetic CT generation

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Gustav Jönsson; [2022]
    Nyckelord :Generative adversarial network; Machine learning; Radiotherapy; Synthetic CT; MR; CT;

    Sammanfattning : Both computed tomography (CT) and magnetic resonance imaging (MRI) have a purpose for radiotherapy. But having two imaging sessions brings uncertainty which makes it beneficial to create synthetic CT (sCT) images from MR images. In this work a Generative Adversarial Network (GAN) was designed and implemented for sCT generation. LÄS MER
