• Seeing the invisible: Enhancing radiation protection competencies through a curricular virtual reality simulation in medical education

  Dabel, J., Meier, N., Süncksen, M., Mayer, L., Zak, G., Teistler, M., … Junga, A. (2026).

  Background: Radiation protection remains abstract in medical training as ionizing radiation is not perceptible to human senses. Theoretical instruction often fails to bridge the gap to safe clinical behavior in the operating room. This study evaluates a newly developed, curricular virtual reality (VR) course designed to visualize scatter radiation and improve medical students’ safety-related self-efficacy.

  Methods: In a prospective study at the University of Münster (winterterm 2025/26), a VR radiation protection module was implemented as a mandatory curricular component for 169 third-year medical students. Data from 139 students who provided written informed consent were included in the evaluation. The core intervention consisted of an immersive VR simulation featuring a virtual operating room with a C-arm based on the proof-of-concept by Süncksen et al. [1] and was specifically adapted for this course. Scatter radiation was rendered as real-time 3D heatmap. Evaluation was conducted via pre- and post-intervention surveys (5-point Likert scales), including the NASA Task Load Index (NASA-TLX) to assess mental demand and frustration. Statistical analysis presented in mean (M)±SD, utilized paired samples t-tests and Cohen’s d.

  Results: The module achieved a global rating of 71.2±21.7 (scale 1-100). Students reported high immersion (M=3.6±0.9) and enjoyment (M=4.1±1.0) with low physical demand (M=1.7±0.9). NASA-TLX scores indicated moderate mental demand (M=2.4±1.1) and task complexity (M=2.5±0.9), suggesting a well-balanced challenge. Comparisons of self-assessment scores in the pre- and post-intervention questionnaires revealed significant improvements across all competency domains (p<0.001). The most pronounced effect was observed for safe positioning within the room (d=1.1; pre: M=2.3±1.0, post: M=3.3±0.9). Overall, 91.7% of students recommended the permanent integration of the VR course.

  Discussion: Virtual reality effectively bridges the gap between theory and practice by rendering invisible radiation hazards visible. The immersive 3D heatmap enables students to experience spatial dose distributions, transforming abstract safety principles into tangible experiences. Our results align with prior research [2], while highlighting the specific impact of high-fidelity heatmaps on spatial awareness. NASA-TLX data confirm the simulation is intellectually stimulating without inducing excessive cognitive demand, ensuring feasibility for mandatory curricular use. Building on institutional VR-expertise [3], this module can help to establish a scalable educational standard that effectively prepares students for radiation-safe behavior in clinical practice.

  Take-home messages: Immersive 3D heatmaps significantly enhance student self-efficacy in radiation-safe positioning. The balanced cognitive load and high student acceptance made this scalable VR module a useable approach for risk-free practical training.

  This study investigates the effectiveness of a hydraulic-pneumatic flywheel system integrated into the rotor of a wind turbine for structural load reduction. The analysis uses the state-of-the-art aeroelastic simulation tools OpenFAST and HAWC2, coupled with a novel Simulink based flywheel and control model, to evaluate fatigue loads mitigation abilities of the flywheel. Fatigue load simulations are performed for cases with and without the flywheel system, with a specific focus on the fatigue life of the tower. The findings indicate that different flywheel control functionalities exhibit varying levels of influence on tower fatigue loading in both simulation environments. A fatigue-life extension of up to 20% is achieved, demonstrating the potential of flywheel control strategies for structural load mitigation.

• Impact of Wind Turbulences on the Energy Yield of a Wind Turbine with a Hydraulic-Pneumatic Flywheel System in its Rotor

  Wind turbulence introduces variations and oscillations in the power output of wind turbines and vibrations of wind turbine components. Higher turbulence intensities lead to significant wind speed fluctuations, necessitating frequent aerodynamic regulation of the rotor in near-rated operating points. Reducing these fluctuations stabilizes the operation of the wind turbine, which reduces power fluctuations in the grid, and which reduces wear and tear in the wind turbine. This study investigates a hydraulic-pneumatic flywheel system designed to leverage these fluctuations by absorbing excess energy during gusts (charging) and releasing it during lulls (discharging), effectively smoothing the power output. The charging phase of this system introduces an additional electrical load by driving hydraulic pumps with electric motors, thereby increasing the generator torque. Simultaneously, fluid movement along the rotor blades induces Coriolis forces, generating a negative torque that slows down the rotor. This flywheel system application reduces rotor speed and pitch angle excursions during peak wind events by storing surplus energy. When the wind speeds drop below rated wind speed due to turbulence, the stored energy is released by transferring the fluid from the tip accumulators to storage tanks in the blade roots, reducing the flywheel inertia, and hence, releasing energy. This bidirectional functionality allows mitigating the downsides of turbulence. The objective of this study is to assess the performance of the flywheel system in stabilizing power output and to quantify the energy yield improvement, with a particular focus on the influence of turbulence intensity.

  The ongoing transition towards inverter-based generation is significantly reducing conventional rotational inertia in power systems, leading to increased rates of change of frequency. To address this challenge, the Hydraulic Variable Inertia Flywheel (HVI-FW) represents a novel alternative for distributed and inherent inertia provision. This paper presents a design tool developed to optimize the geometric parameters of the novel flywheel, with respect to specific energy. A parameter study is conducted by varying key geometric dimensions, such as radius and height. The results demonstrate that the HVI-FW can achieve significantly higher specific energy than conventional flywheels, particularly for small radii, making it well suited for coupling with small, synchronously rotating electrical machines. The findings highlight the potential of the HVI-FW as an effective solution for providing distributed inertia in future low-inertia power systems.
