OpenVSP (https://openvsp.org) allows the user to create a 3D model of an aircraft defined by common engineering parameters. This model can be processed into many formats suitable for engineering analysis. Among other options, OpenVSP supports export of its parametric 3D aircraft data to the X3D standard. X3D files (*.x3d) can be displayed on the Internet embedded in HTML. The HTML-internal viewer X3DOM produces good results and should be selected. This allows us to share 3D aircraft design results, without any software requirements for the recipient, besides having an Internet connection and a browser. Another easy way to distribute 3D aircraft is embedding them in PDF files. OpenVSP files (*.vsp) can be viewed by OpenVSP. X3D files (*.x3d) can be viewed by many viewers like FreeWRL or view3dscene. --- OpenVSP-Connect – Aircraft preliminary sizing tools need a 3D visualization to show results. OpenVSP has such 3D visualization capabilities, it is easy to use, but unfortunately lacks an interface to input consistently calculated aircraft parameters. Such an interface has been programmed with Excel and is called OpenVSP-Connect (https://purl.org/OpenVSP). Aircraft are sketched from about 50 parameters. These are automatically converted to more than 3500 parameters to make up an input file with parametric aircraft data in OpenVSP Version 2 format (*.vsp). Just two input parameters are sufficient to get started in OpenVSP-Connect's "automatic mode": cruise Mach number and number of passengers. --- OpenVSP-Connect Hangar – OpenVSP-Connect Hangar (https://purl.org/OpenVSP/Hangar) is a collection of aircraft designed with OpenVSP-Connect. --- Airbus A320 – The Airbus A320 has been modeled as a 3D aircraft merely from a few parameters found at Wikipedia with OpenVSP-Connect. See the 3D A320 on https://purl.org/OpenVSP/A320. Find a set of files with 3D content (and 2D preview) of the A320 in this dataset: https://doi.org/10.48441/41201.3359. The 3D content in a PDF file is visible as such only when the file is viewed in the Acrobat Reader. In a web browser, the 3D content in a PDF file is displayed only statically (it cannot be rotated).

Bats, in particular, pose a methodological challenge due to their nocturnal and aerial behavior, and many species are difficult to detect using ground-based surveys alone. In this study, we evaluated the potential of multicopter-based acoustic transects as a complementary method to traditional ground-based bat surveys. We compared species group composition and activity levels acoustically recorded along identical transects at ground level and at 104 m height with a multicopter across three habitat types (forest, meadow, and waterbody). Our results showed that elevated airspace appears to represent a largely distinct foraging habitat that is only partly linked to ground-level habitat structure and is primarily used by Nyctaloid and Pipistrelloid echolocation groups. Our findings are in line with what is already known about the spatial behaviour of Myotis bats, as these were recorded almost entirely near the ground. We also tested whether the two multicopter types influenced acoustic detection rates and found no significant differences when recording devices were properly distanced and oriented away from the multicopter. Thus, this paper contributes by suggesting how multicopters can serve as a new mobile measurement method to extend the vertical reach of acoustic bat surveys. This further helps to identify species-specific habitat use in hard-to-reach regions, such as the risk area around the nacelle of a wind turbine. This information can then be used to inform bat conservation and mitigation efforts.

Abstract: This study examines the impact of two multicopters, differing in size and weight (ConVecDro hexacopter, DJI Mavic 2 Pro quadcopter), on the activity of bats assigned to three distinct echolocation groups. The objective was to define thresholds (in decibels) below which bat echolocation groups show weak or no impact on activity. Using the known noise profile of the multicopter and a model of sound attenuation in air, these thresholds were then used to determine optimal microphone placement distances by estimating frequency-specific sound levels at increasing recording distances. Directional properties of the recording device were also considered.

Demographic shifts increasingly challenge treatment centers: Whereas affected individuals were historically younger male trauma patients without comorbidities, most patients today are older than 60 years and frequently multimorbid. The proportion of incomplete SCIs is also rising. Rehabilitation aims to achieve the highest possible level of independence, with restoration of walking ability becoming a central goal in individuals with incomplete SCI. Long term outcomes depend on neurological recovery, medical and therapeutic interventions, and social participation, highlighting the importance of gait rehabilitation for autonomy and quality of life. Therapeutic approaches for gait recovery, however, are highly heterogeneous, and no standardized protocol exists. This variability limits comparability and underscores the need for a structured overview of current interventions. A scoping review can systematically map available evidence and identify key concepts, methodological limitations, and existing knowledge gaps to support evidence based practice in this evolving field.
