6. Tracking Optimization in Agrivoltaic Systems : A Comparative Study for Apple Orchards
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Agrivoltaic (APV) systems, based on the co-location of solar panels and crops, are an innovative solution to land-use conflicts that often arise between agriculture and energy production. Their optimal functioning starts with efficient management and sharing of light between solar panels and underlying plants. READ MORE

7. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE

8. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm
University essay from KTH/Tillämpad fysikAbstract : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.

9. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

10. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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.
