In-Situ Topography Characterization of Mirrors in a Six-Degree-of-Freedom Nanopositioning System
This dataset provides high-resolution surface topography maps of the four reference mirrors in the NPS6D200 six-degree-of-freedom (6-DOF) nanopositioning system, measured under real operating conditions. The data were acquired using a fully in-situ method based on angular measurements from three external…
Influence of land cover, native shrub availability, and predator presence on the habitat selection of Meriones hurrianae…
Land use and land cover changes in the Thar Desert have contributed to a marked decline in regional biodiversity. This study examined the habitat selection behavior of the Indian desert gerbil (Meriones hurrianae) using statistical analysis of data obtained from field-based ecological surveys employing…
Thermal Analysis of a Coil Assembly in a Nanopositioning Drive System via Reduced-Complexity CFD Modeling
This dataset contains the measurement data to the corresponding open acces paper "Thermal Analysis of a Coil Assembly in a Nanopositioning Drive System via Reduced-Complexity CFD Modeling". The paper presents the development and verification of a reduced model CFD simulation for a nanopositionings drive…
BirdNET-Based Bird Species Detections and Environmental Data from 20 Temperate Forest Sites in Jena, Thuringia (2024)
This dataset contains bird detections from 20 forest sites around Jena, Thuringia, Germany, collected via passive acoustic monitoring across the four seasons of 2024, along with additional environmental variables describing the sites. These sites form part of the “WZE@Jena” monitoring project (Waldzustandserhebung…
Synchrotron X-ray nano-tomography datasets of unhydrated and 12, 16 and 20h hydrated tricalcium silicate particles
Reconstructed synchrotron X-ray nano-tomography (PXCT) datasets of unhydrated (0h) and hydrated (12h, 16h, 20 h) tricalcium silicate (C3S) embedded in epoxy resin. The C3S was sieved to a particle size <10 µm. For the hydration, 15 g of C3S was mixed with 45 g filtered, saturated Ca(OH)2-solution and…
Large SEM-BSE images of hydrated alite-belite mixtures at the ages of 7, 14, 28 and 56 days
This dataset contains a set of images of alite (C3S) and belite (C2S) mixtures (3:1, 1:1, 1:3 in weight). Specimen preparation The powders were mixed before adding water. The water to solid ratio used was 0.5. The specimens were filled in small containers and were allowed to hydrate under a saturated…
Oryx: Multi-node Radio Channel Sounding for UAVs and Ground-stations
To facilitate situational awareness in UAVs using radio waves, baseband algorithms must be verified using high-quality measured datsets that reflect real-world scenarios. This dataset contains radio channel measurements between stationary (ground- and rooftop-mounted) and mobile (UAV- and vehicle-mounted)…
Investigation of long-term distance measurement repeatability in a large-range nanopositioning machine combined with a laser…
This dataset consists of the measurement repeatability of a nanopositioning machine equipped with a laser focus sensor (LFS). The highlights of the results are: The combination of nanopositioning machine and laser focus sensor allows for dimensional measurements close to sub-10 nm performance over a…
Fyoris : Full-polarimetric V2I MIMO channel sounding data sets @2.53GHz in urban environment, together with pertinent antenna…
Seven measurement runs, selected from a measurement campaign in Bonn, Germany, are provided. The environment is urban, the context is V2I from an elevated base station, the set-up is fully polarimetric MIMO with two 16 dual-pol element stacked circular arrays, configured as two circular rings of 8 elements…
Elowen : MIMO Channel Sounding and Characterization in an Urban Macro Cell
The measurement campaign was performed in Cologne (Germany) using a RUSK MIMO channel sounder operating at 2.53 GHz. The fixed transmitter has been mounted on a roof top of an approx. 30m high building whereas the mobile receiver has been set up in a car. The application of high resolution parameter…
