Digital image correlation measurement of linear elastic steel specimen

<p>The dataset comprises the axial and lateral displacements on the surface of a plate with a hole subjected to tensile load. The displacement data are measured by digital image correlation and the material is assumed to behave linear elastic. The material under investigation is a common low-carbon steel alloy of type S235. The displacement data are used for calibration of a linear elastic constitutive model using parametric physics-informed neural networks and finite elements. For that purpose, the dataset comprises both the raw experimental displacement data and displacement data interpolated onto a regular grid using linear interpolation, where the interpolation routine is provided as well.</p>

QuaLiKiz-v2.6.2 linear instability spectra based on JET experimental plasma profiles

<p>This dataset was used to train the QuaLiKiz-neural-network (QLKNN) model, QLKNN-jetexp-15D, described within the following published article: <a href="https://doi.org/10.1063/5.0038290">https://doi.org/10.1063/5.0038290</a>. It was generated with approximately 33 million standalone evaluations of QuaLiKiz-v2.6.2, each performed with a standard vector of 18 wavenumbers. Only approximately 21 million of these are kept for training due to various consistency checks applied to the code outputs. More information about the QuaLiKiz code can be found at <a href="https://www.qualikiz.com">www.qualikiz.com</a>.</p> <p>The data is saved under 3 keys in HDF5 format: &quot;/input&quot;, &quot;/spectrum&quot;, and &quot;/wavenumber&quot;. The &#39;/input&#39; key contains the inputs used for the QuaLiKiz evaluations, representing the local plasma parameters extracted from experimental measurements from the JET plasma device in Culham, UK, along with variations of select parameters according to propagated experimental uncertainties. The &quot;/spectrum&quot; key contains the linear growth rate and frequency spectra corresponding to the 2 most dominant microinstabilities determined by the calculation (s0 = dominant, s1 = sub-dominant). The &quot;/wavenumber&quot; key contains an array representing the standard set of 18 wavenumbers (<span class="math-tex">\(k_y \rho_s\)</span>) was used to generate the spectra (k0 = lowest wavenumber, k17 = highest wavenumber).</p>

<p>This is a data supplement to <strong>&#39;Vertical land motion reconstruction unveils non-linear effects on relative sea level changes from 1900-2150</strong>&#39;. It presents a global-scale Vertical Land Motion (VLM) reconstruction that resolves height changes in the period 1995-2020. It is based on the joint probabilistic analysis of an extensive network of more than 11,000 GNSS stations, tide gauges, and satellite altimetry. The approach used to derive this reconstruction is described in the paper. The dataset variables are explained in the .pdf file.</p>

CSM08 Small mammal host-parasite sampling data for 16 linear trapping transects located in 8 LTER burn treatment watersheds at Konza Prairie

Data set contains summaries (summer) of the number of individuals of each species of small mammal captured (relative abundance) on each transect. Each record contains date, treatment, transect, trap station, species, specimen number, recapture status, specimen disposition, external body measurements (where applicable), reproductive information, and miscellaneous associated comments. These sampling records are based on nightly captures during one 4-night trapping period in summer (June through August) for each of 16 permanent transects established on eight fire treatments (two transects per treatment). These treatments include two seasonal burn watersheds (SpB, SuB), two reversal burn watersheds (R1A, R20A), one annual burn watershed (1D), two 4-year burn watersheds (4B, 4F, and one 20-year burn watershed (20B). None of these treatments implement bison grazing.

Investigating terrestrial isopod abundance in sandplain grassland using a multiple linear regression

<p>Most North American species of terrestrial isopod (Isopoda) have been introduced from Europe. Sandplain grassland is a globally rare habitat that is abundant on Nantucket Island, Massachusetts and the abundance of terrestrial isopods in the habitat has never been studied. The objective of this project was to develop a model to explain isopod abundance based on vegetation characteristics within Sandplain grassland and use this model to test for land management effects (prescribed burning and mowing) on isopod abundance. I counted terrestrial isopods from 175 pitfall traps set for one week and used multiple linear regression with several selection algorithms to select the best model. The vegetation characteristics I used as regressors do not appear to explain terrestrial abundance well and the final model only contains the percent grass coverage as a regressor. The model suggests that terrestrial isopods decrease in abundance with increasing grass coverage and it explains 29 percent of the data. When management effects are incorporated, the model suggests that mowing significantly increases isopod abundance.</p> <p>Funding for this project came from the Nantucket Islands Land Bank, Nantucket Land Council, and the Nantucket Biodiversity Initiative.</p> <p>Associated vegetation data is in the published &quot;Effects of Sandplain Grassland Management on Spider Richness and Abundance on Nantucket Island&quot; dataset.&nbsp; Sampling methods are in the thesis linked from that dataset.</p> <p>allisopodData.csv - isopod counts by trap<br> dataDictionary.csv - descriptions of variables<br> mckenna-foster_2009.pdf - a report submitted to NBI and used as part of a statistics class at the University of Wisconsin-Green Bay</p> <p>&nbsp;</p>

Dataset for "Helicity proxies from linear polarisation of solar active regions"

<p>The <span class="math-tex">\(\alpha\)</span>&nbsp;effect is believed to play a key role in the generation&nbsp;of the solar magnetic field. A fundamental test for its significance in&nbsp;the solar dynamo is to look for magnetic helicity of opposite signs&nbsp;in the two hemispheres, and at small and large scales. However, measuring magnetic helicity is compromised by the inability to fully infer the&nbsp;magnetic field vector from observations of solar spectra,&nbsp;caused by what is known as the <span class="math-tex">\(\pi\)</span>&nbsp;ambiguity of&nbsp;spectropolarimetric observations.&nbsp;We decompose linear polarisation into parity-even and parity-odd <em>E</em> and <em>B</em> polarisations,&nbsp;which are not affected by the <span class="math-tex">\(\pi \)</span> ambiguity.&nbsp;Furthermore, we study whether the correlations of spatial Fourier&nbsp;spectra of <em>B</em>&nbsp;and parity-even quantities such as <em>E&nbsp;</em>or&nbsp;temperature <em>T</em> are a robust proxy for magnetic helicity of solar magnetic fields.&nbsp; We analyse polarisation measurements of active regions observed by the&nbsp;Helioseismic and Magnetic Imager on board the Solar Dynamics observatory. Theory predicts&nbsp;the magnetic helicity of active regions to have, statistically, opposite signs in the two hemispheres.&nbsp;We then compute the parity-odd <em>EB</em> and <em>TB</em> correlations, and test for systematic preference of&nbsp;their sign based on the hemisphere of the active regions.&nbsp;We find that: (i) <em>EB</em> and <em>TB</em> correlations are a reliable proxy for magnetic helicity, when&nbsp;computed from linear polarisation measurements away from spectral line cores, and (ii)&nbsp;<em>E</em>&nbsp;polarisation reverses its sign close to the line core. Our analysis reveals Faraday&nbsp;rotation to not have a significant influence on the computed parity-odd correlations.&nbsp;The <em>EB</em>&nbsp;decomposition of linear polarisation appears to be a good proxy for magnetic helicity&nbsp;independent of the <span class="math-tex">\(\pi\)</span>&nbsp;ambiguity. This allows us to routinely infer magnetic helicity&nbsp;directly from polarisation measurements.</p> <p>The full article can be found at&nbsp;https://arxiv.org/abs/2001.10884</p>

Binaural room impulse responses recorded with KEMAR of a 19-channel linear loudspeaker array

<p>BRIRs for 19 different loudspeakers placed in room Calypso at the Telefunken-building of TU Berlin were measured. The room is a studio listening room. The 19 loudspeakers constituted a linear loudspeaker array with a inter-loudspeaker distance of roughly 15cm. The measurement was done with the KEMAR (type 45BA) with the corresponding large ears (type KB0065 and KB0066) and Fostex PM0.4 loudspeakers. The dummy head was rotated from −90° to 90° in 1° steps. The measurement was repeated with the head wearing AKG K601 open headphones.</p>
