3D scans of two types of railway ballast including shape analysis information

This data set contains 3D scanner data of two types of railway ballast “Calcite” (stems from Croatia) and “Kieselkalk”, also known as Helvetic Siliceous Limestone, (stems from Switzerland). From each type of ballast 25 stones are scanned. The files are provided in .ply format. For the scanned meshes several shape descriptors are provided: elongation, flatness, sphericity, convexity index. Additional to the 3D scans, both simplified and rounded versions of the meshes are included. For these meshes information on three different angularity indices are available. The scanned ballast types are the same, as  previously investigated in uniaxial compression tests and direct shear tests: Suhr, Bettina, & Six, Klaus. (2018). "Compression tests and direct shear test of two types of railway ballast [Data set]" Zenodo. http://doi.org/10.5281/zenodo.1423742   A detailed shape analysis of the results is conducted in: Bettina Suhr, William A.

This dataset contains the 25 raw measurements/scans taken before the mesh creation step for object 1984.132.4148 in the collections of York Archaeological Trust. 1984.132.4148 is a dish. Close analysis was not undertaken at time of data capture. Scanning was not complete. Holes in scan data: one small circle at the very centre of the base of the dish, and gaps in data capture under the rim.  Data was captured using a Zeiss Comet L3D 2 5M at 100 FOV to enable the analysis of use-wear on archaeological objects. The model is scaled in millimetres. This dataset consists of 27,629,672 points - additional metadata included in associated spreadsheet.

RAKSILA 3D. Laser scanning survey of the street fronts and green areas in Raksila, Oulu (FINLAND)

The video shows the preliminary results of the laser scanner survey of Raksila district in Oulu, Finland. Raksila is an important historical trace in the development of the urban planning of the city of Oulu. The district of Raksila is mainly a well-preserved residential Neighborhood characterized by a strong typicality.The general plan consists of a regular structure and a system of street fronts on the road are ordered and in an homogeneous profile. Despite this, Raksila still has no detailed and updated guidelines capable of managing all different types of interventions allowed (renovation, restoration, repair actions, possible modifications). For this reason, a laser scanner survey and detailed documentation have been created, through which all the elements and characteristics of the place have been defined and collected in sort of atlas and inventory reports. This new documentation is going to constitute the base for the definition of new guidelines, a practical support and analysis for future interventions that can be carried out in total respect of this heritage. This topic is inserted as case study for developing the Research Project n. 746215 entitled "Preserving Wooden Heritage". The project is financed by the European Commission with an Individual Marie S. Curie Fellowship assigned to PostDoctoral Researcher Sara Porzilli, who is working at the University of Oulu - Finland.

Scan files, 3D reconstructions, data spreadsheet and supplementary files for Heterochrony and parallel evolution of echinoderm, hemichordate and cephalochordate internal bars

Deuterostomes comprise three phyla with radically different body plans. Phylogenetic bracketing of the living deuterostome clades suggests the latest common ancestor of echinoderms, hemichordates and chordates was a bilaterally symmetrical worm with pharyngeal openings, with these characters lost in echinoderms. Early fossil echinoderms with pharyngeal openings have been described, but their interpretation is highly controversial. Here, we critically evaluate the evidence for pharyngeal structures (gill bars) in the extinct stylophoran echinoderms Lagynocystis pyramidalis and Jaekelocarpus oklahomensis using virtual models based on high-resolution X-ray tomography scans of three-dimensionally preserved fossil specimens. Multivariate analyses of the size, spacing and arrangement of the internal bars in these fossils indicate they are substantially more similar to gill bars in modern enteropneust hemichordates and cephalochordates than to other internal bar-like structures in fossil blastozoan echinoderms. The close similarity between the internal bars of the stylophorans L. pyramidalis and J. oklahomensis and the gill bars of extant chordates and hemichordates is strong evidence for their homology. Differences between these internal bars and bar-like elements of the respiratory systems in blastozoans suggest these structures might have arisen through parallel evolution across deuterostomes, perhaps underpinned by a common developmental genetic mechanism.

3D Laser Scanning Data: Public Square in Murcia and Engineering Laboratory at the University of Alicante

This dataset includes 3D terrestrial laser scans obtained using the Leica C10 ScanStation. The data covers two distinct scenarios: <ol> <li> Public Square in Murcia Capital: This dataset includes two scan positions within a public square located in Murcia. Three HDTarget markers were placed, and their center or vertex coordinates are provided in the accompanying _vertices.txt file. The scans were conducted with the laser scanner leveled, but they are not registered. </li> <li> Engineering Laboratory at the University of Alicante: This dataset consists of two scans of the Ground Engineering Laboratory at the University of Alicante. The scans were conducted with the same leveled laser scanner, and no targets were used. Between the two scans, some elements in the laboratory were slightly moved, which can be identified by comparing the point clouds. </li> </ol>

3D ARPES angle scan collection

This repository contains a number of 3D Angle Resolved Photoemission Spectroscopy (ARPES) datasets. Each datasets represents the photoemission intensity (normalized) as function of energy and two crystal momoentum components, I(E,k_x,k_y). These were all obtained performing "angle-scans", i.e. measuring a series of 2D spectra I(E,theta) and varying the other emission angle (phi). These angle coordinates were then warped into the crystal momentum components, centered at the Gamma point. These datasets cover 19 material systems:  Au(110), Au(111), Bi2Se3(111), CoO2, on Au(111), CrSBr(001), Graphene on Ir(111), Graphene on Ru(0001), single-layer MoS2 on Au(111), single-layer NbSe2 on bilayer graphene, NdTe3(010), Pd(100), Pd(111), Pt(111), Rb-doped Bi2Se3(111), Ru(0001), P-δ-layer on Si(001), single-layer TaS2 on Au(111), single-layer WS2 on Ag(111) and single-layer WS2on Au(111).
