  1. 11. Uncertainty Estimation in Radiation Dose Prediction U-Net

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

    Author : Frida Skarf; [2023]
    Keywords : Radiation dose prediction models; U-net; quantile regression; Monte Carlo Dropout; epistemic uncertainty estimation; aleatoric uncertainty estimation; Stråldospredicerande modeller; U-net; kvantilregression; Monte Carlo Dropout; epistemisk osäkerhetsskattning; aletorisk osäkerhetsskattning;

    Abstract : The ability to quantify uncertainties associated with neural network predictions is crucial when they are relied upon in decision-making processes, especially in safety-critical applications like radiation therapy. In this paper, a single-model estimator of both epistemic and aleatoric uncertainties in a regression 3D U-net used for radiation dose prediction is presented. READ MORE

  3. 12. SHADING ANALYSIS OF AGRIVOLTAIC SYSTEMS : The shading’s effect on lettuce and potato from elevated agrivoltaic system in Sweden

    University essay from Mälardalens högskola/Framtidens energi

    Abstract : The world is progressing towards a more sustainable society, where renewable energy sources, including solar energy, play a crucial role. This study aims to address the conflict between agriculture and energy production by exploring the installation of solar panels on farmland. READ MORE

  4. 13. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)

    University essay from KTH/Fysik

    Author : Oscar Wistemar; [2023]
    Keywords : Gamma-Ray Bursts; Astrophysics; Engineering Physics; Gamma-Blixtar; Astrofysik; Teknisk Fysik;

    Abstract : Gamma-ray bursts (GRBs) are some of the most energetic events in the universe. Shocks occurring below the photosphere are likely radiation mediated shocks (RMSs) and are suspected to shape the spectra. Due to computational costs of simulating RMSs, models had not been fitted to data and a faster model was needed. READ MORE

  5. 14. Research of appropriate luminance level of monitor screens in workplace

    University essay from Högskolan Dalarna/Informatik

    Author : Mengfei Wang; Shiqi Shu; [2023]
    Keywords : Screen brightness; Paradigm Color; Lighting conditions; Human eye preference; skärmens ljusstyrka; Paradigm färg; ljusförhållanden; Mänskliga ögonpreferenser;

    Abstract : MÅL: Huvudsyftet med den här studien är att undersöka hur naturligt ljus påverkar det mänskliga ögats preferens för skärmens ljusstyrka när man tittar på en datorskärm. METODER: Tre experiment genomförs för att mäta i vilken utsträckning solljus förändrar bakgrundsljuset i form av solstrålning. READ MORE

  6. 15. Characterization of Lamps of IRF Solar Simulator

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Mrunmayee Sonna; [2023]
