Plant fibre reference collection - Arecales
<p>Arecales is the order that groups all palm trees, these plants are quite iconic of tropical context with coconut, rattan palm trees among others. Leaves and stem are the plant parts that are exploited for handicraft purposes. Palm trees, like all Monocotyledon plants, do not produce wood (no cambium, no secondary growth) therefore, their vascular system is never renewed and needs to be protected with fibrous caps. This anatomical arrangement is significant as there is vascular replacement through time vascular cells continue to thicken and lignify their wall for many years. Therefore, the plant grows taller without significantly increasing in diameter (Tomlinson <em>et al</em>., 2011: 13). This is particularly striking of coconut palm tree which stalk’s diameter will not exceed 30 centimeters while the plant height could reach more than 30 meters. Palm tree stems got unique features of growth that produce confounding variability in anatomy (Thomas&De Franceschi, 2013: 5).<br> Of anatomical characters of interest is the vascular system which is compound of dorsal vascular fibrous caps are generally more developed in the cortical area (external parts) than in the central part and are of different shape. The morphology of these vascular caps (reniforma, lunata, etc.) among others vascular features (transverse commissure) are interesting as they can help to distinguish palm trees, sometimes to the genus level and could also inform us about plant mechanism and property (Thomas, 2011: 33).</p> <p>Thomas, R. 2011.

Full dataset of several mechanical tests on an S355 steel sheet as reference data for digital representations
<p>The dataset provided in this repository comprises data obtained from a series of characterization tests performed to a sheet of typical S355 (material number: 1.0577) structural steel (designation of steel according to DIN EN 10025-2:2019). The tests include methods for the determination of mechanical properties such as, e.g., tensile test, Charpy test and sonic resonance test. This dataset is intended to be extended by the inclusion of data obtained from further test methods. Therefore, the entire dataset (concept DOI) comprises several parts (versions), each of which is addressed by a unique version DOI.</p> <p>The data were generated in the frame of the digitization project Innovationplatform Material<em>Digital </em>(PMD) which, amongst other activities, aims to store data in a semantically and machine understandable way. Therefore, data structuring and data formats are focused in addition to aspects in the field of material science and engineering (MSE). Hence, this data is supposed to provide reference data as basis for experimental data inclusion, conversion and structuring (data management and processing) that leads to semantical expressivity as well as for MSE experts being generally interested in the material properties and knowledge.</p>

Dataset for a Feasibility Study for Accelerated Reference Point Determination Using Close Range Photogrammetry
<p>The Global Geodetic Observing System (GGOS) aims for an accuracy of 1 mm in position concerning a global geodetic reference frame such as the International Terrestrial Reference Frame (ITRF). To derive a global frame, several space geodetic techniques are combined. The combination procedure requires the geometric relations between the invariant reference points of these techniques, the so-called local tie vectors. Each space geodetic technique defines its reference point individually, so the determination of the position of the reference point varies significantly between techniques. Within the international GeoMetre project, measurement systems and analysis strategies are developed to improve the quality of local tie vectors and, thus, the quality of the resulting global frame.</p> <p>The use of close range photogrammetry to determine the reference point of a telescope used for Satellite Laser Ranging (SLR) at the GGOS core station Wettzell in September 2020 is considered as a milestone in this project. This contribution deals with a novel approach for an accelerated reference point determination using close range photogrammetry. In comparison to the conventional photogrammetric approach, published so far, this new approach leads to a significant reduction in recording time. However, in case of inappropriate measurement configuration the approach also bears the risk of biased results. Most importantly, the new approach has the potential to be automated, which is one of the primary calls of GGOS for reference point determinations.</p>
