Crystallographic texture-property data set originating from a simulated multi-step metal forming process
No full textThis publication contains a set of 76980 samples of crystallographic textures (as lists of orientations) and corresponding properties (Youngs modulus E and an anisotropy measure R*, similar to the Lankford coefficients, in three room directions). The data originates from a simulated multi-step metal forming process. The simulation was constrained to perform seven successive process steps of 10% strain at the material point in different directions. In each step, the orientation of the tension operation is chosen randomly from a set of 25 uniformly distributed orientations in the orientation space SO(3)

Inklusive Klassenlabels und registrierte RGB-Bilder
No full textThe dataset contains 44 hyperspectral near-infrared images of bulky waste samples. For each hyperspectral image, there is also an RGB and a label image assigning one of 9 classes to each pixel. The majority of samples are crushed furniture from IKEA and the other objects are from a real waste plant or self-collected bulky waste. Details of the file structure are given in "readme.txt" of the provided dataset. The measurements are part of the work described in https://publica.fraunhofer.de/entities/publication/dde5f89c-f87b-4644-b084-f4edf66c4b19/detailsDas Projekt wird von dem Bundesministerium für Ernährung und Landwirtschaft (BMEL) gefördert. Projektträger ist die Fachagentur Nachwachsende Rohstoffe e.V. mit der funding reference 2220HV048A.Three tiff-files files per sample collection are given in this dataset, with 44 bulky waste sample collections in total. One RGB image (3300x4782 pixel), one hyperspectral image (550x797 pixel with 210 channels) and one gray-scale image (3300x4782 pixel) encoding a class in each pixel (class index = gray scale value / 12). For hyperspectral imaging, the camera FX17e from SPECIM was chosen. The camera collects hyperspectral images with 224 bands ranging from 900nm to 1700 nm. 14 channels at the edge of the spectrum have been removed in the provided images, due to a low sensitivity. The frame rate was set to 104.17 Hz, resulting in a resolution of 1mm/pixel in both axes of the image. A prism-based RGB line scan camera (SW-4000T-10GE) was used to make recordings of the sample scenario. These images were utilized for labelling and conventional RGB image analysis. The frame rate of the RGB camera was set to 625 Hz. The spatial resolution was 0.15mm/pixel. As a light source, halogen lamps were used for both cameras. By moving the samples on a conveyor belt with a speed of 0.108 m/s, images with two spatial axes were constructed using the push-broom method. The scanning lines of the hyperspectral and the RGB camera differ by a few centimeters, which was corrected using a marker-based registration. Each pixel in a hyperspectral image corresponds to a 6x6 pixel region in the RGB and the label image. To have a one-to-one pixel correspondence for all images, one can downsample the RGB and label images by a factor of 6

Microstructural damage dataset (pytorch geometric dataset)
No full textThis data set contains information about microstructure-sensitive damage in ferritic steel (EN 1.4003) specimens. We provide both graph and tabular data sets.
In the graph data set, each node is a grain in the material, and each edge connects adjacent grains. Annotation is provided to each of the grains mentioning if it developed damage (protrusion in this case) during a fatigue test.
The annotation is provided based on fatigue tests performed on the specimen.The readme.md file provides an example on how to read the file
Export Potentials of Green Hydrogen - Methodology for a Techno-Economic Assessment. Annex A.1 - Modeling parameters
No full textThis working paper describes the quantitative and model-based methodology used in HYPAT to assess hydrogen and Power-to-X (PtX) export potentials in the countries Morocco, Ukraine, Namibia, Turkey, United Arab Emirates, Kenya, Chile, Canada, Brazil, and New Zealand. The results of the techno-economic assessment are further used as a basis for a global hydrogen and PtX atlas, and as an indication of the price development of hydrogen and PtX
ÖFIT Bevölkerungsumfrage 2019
No full textIn dieser Umfrage geht es um die Haltung der Befragten zu neuen Technologien, insbesondere um die Nutzung und Erfahrung mit intelligent vernetzten Geräten im Haushalt, also Smart Home bzw. Ambient Assisted Living Anwendungen in verschiedenen privaten Einsatzbereichen. Nutzer:inner von Smart Home Anwendungen wurden nach der Wichtigkeit verschiedener Kaufkritierien befragt. Nicht-Nutzer:innen von Smart Home Anwendungen wurden nach Gründen für die Nicht-Nutzung befragt. Für die Umfrage wird neben dem Datensatz (in zwei Versionen: sowohl mit Werten als auch mit Label) der Fragebogen mit dem Codeschema bereitgestellt. Zusätzlich werden die vom Dienstleister verfügbaren Angaben zu den Methoden der Datenvalidierung, Bereinigung und Gewichtung der Datensätze bereitgestellt.Die Daten werden jeweils in zwei Formaten zugänglich gemacht.

Time Series of wear test for roller-type pitch bearings of wind turbines
No full textThis data set contains time series and additional information for a test program for pitch bearings of wind turbines. The program covers two distinct operational scenarios: the standstill of the bearing under rated speed and the active pitch cycles caused by the IPC. It is designed for rollerr-type pitch bearings, but can be applied to toher pitch bearings as well. It bases upon the aero-elastic simulation time series (see links).This is a MATLAB structured data set. Whereever possible the data is compiled in the table format to allow easy understanding
