Data from Block-on-Ring Wear Tests of Victrex FG340 in Dry Sliding versus AISI 52000 steel
<p>This is re-published copy of an existing publication (<a href="https://dx.doi.org/10.17632/nbz7hs4ckn.1">https://dx.doi.org/10.17632/nbz7hs4ckn.1</a>)</p> <p>The data has been collected during Block-on-Ring Wear Tests on "Victrex PEEK FG340". The tests were done in dry sliding against AISI 52000 steel rings, ground twist-free to 𝑅a = 0.14–0.19 μm, 𝑅z = 1.5–1.9 μm and with a hardness of 60–62 HRc in standard laboratory atmosphere (21–25 °C, 40–60% rH). The research objective was to determine the coefficient of friction of this material pair for use in the calculation of transient temperatures and dimensions during the process of designing a journal bearing. Test conditons were conducted on an ASTM G137-compliant Block-on-Ring tribometer from Tribologic GmbH, Germany. The tests were conducted at 1 MPa in uniform, unidirectional sliding at 1.0 m/s and lasted 6 hours each, resulting in a total sliding distance of 21,600 m for each test. Block cross section was 16 mm² and fiber orientation (if applicable) was nominally parallel (with respect to an ISO 527-1A speciment). Individual test results for the coefficient of friction, the linear, time-dependent wear rate and the counter body temperature were calculated from time-resolved sensor data. For this, data from the running-in phase of each experiment was ignored. For statistical reasons eight individual tests were conducted and - after elimination of outliers using Nalimov's variant of the Grubbs test - arithmetic mean and (frequentist) confidence intervals (95 %) were determined for the aforementioned quantities. This resulted in a COF of 0.28-0.32, a linear, time-dependent wear rate of 0.6 - 1.0 µm/h and a counter body temperature of 31.2 - 32.4 °C.</p> <p>For each of the 8 conducted tests, a plain-text columnar data file is provided ("*.proc"). Instead of including one or more header lines for denoting the meaning, name and unit of each column, a yaml-formatted, human-readable header file is provided ("*.yaml"). Column-indexing starts at 0, i.e. the first column of the data file is represented by index 0. Data and header files are matched by their test ids, which range from 555689 to 555696 in this data set.</p>
Data for: Distance calibration via Newton's rings in yttrium lithium fluoride whispering gallery mode resonators
<p>Dataset of Newton's rings images captured through the short face of a trapezoidal prism with a whispering gallery mode resonator positioned behind the prism. Each file corresponds to an applied piezo voltage over a voltage sweep decreasing in voltage steps of 0.1V (file names multiplied by 10). Both image data and oscilloscope data are included. Runs 18-27 & 42-53 use a green (530+-2 nm) filter and Runs 28-41 use a red (670+-2 nm) filter.</p> <p>crop-images.ipynb is used to process the raw images located in FullDataset.zip into grayscale jpg images, these processed images are then fed into Ringanalyzer-simplified.ipynb that calls from RingAnalyzer.py to convert the 2-D images to a signal-radius plot based on fits of an elliptical pattern, finding ellipticity, centroid, and rotation angle.</p> <p>process_run_logfit.m ultilizes the 1-D signal plot used to convert the piezo voltages to coupler distances, then a Lorentz fit is applied to the data from the oscilloscope - using lorentzfit.m to perform the fit. The final result is a log plot of the coupling linewidth as a function of distance. </p> <p>The data for resultant plots can be found in ProcessedDataset.zip and can be plotted by plot_processed_run.m.</p> <p>Figure 3.zip contains just the data subset used to generate Figure 3, with fig3.m to generate the figure.</p>

Shark Bone Ring
3D model of a shark bone ring. During excavation, over 70 vertebrae from the porbeagle shark, Lamna nasus, were found, nearly all between the Choir and central nave of the church. Like this seen here, these bones had been worked on and shaped into rings. They are probably the rings on which hung the curtain that church audits described at this location. In the old days, porbeagle shark bones were in high estimation as curtain rings, for instance for bed closets. Physical object held at the National Museum of Iceland nr: 2005-36-0434.

Ballachraggan - reported cup & ring marks
This was recorded on the Northern Antiquarian website on their visit to the Ballachraggan chambered cairn near Callander. It is on a small platform of rock about 150m NE of the cairn on the side of a prominent knoll - ''two large cup-markings, with the more easterly one of the two seeming to have a carved arc along its edge.'' This was visited and recorded on 14/1/19 and appears to be natural. The local conglomerate rock contains rounded pebbles which weather out of the rock matrix leaving cup-like depressions. There are many examples of these natural 'cup marks' on rocks and on the numerous conglomerate boulders in this area OS REFERENCE NN 68174 06583 Source: Objaverse 1.0 / Sketchfab
Peace Stone - Cup & Ring Marked Stone
This stone is located near Malling Farm at the Western side of the Lake of Menteith. It Has 22 cup marks around which are a network of incomplete rings, curved lines & grooves. When it was first photographed and sketched recorded at the end of the 19th century these unique markings were much more visible. Unfortunately the stone has been much abused since then, having been moved, damaged and much eroded to the point where the complex patterns are virtually indiscenable in the field. Today the stone lies neglected amongst other field clearance boulders within a bracken infested strip enclosed by an old wall and a modern high stock/deer proof fence. Fortunately 3D modelling can still reveal some degree of the former intricate surface decoration. Scotland's Rock Art Project (ScRAP Ref. 362) Canmore Ref. 44622 This stone was recorded and 3D modelled by Nick Parish of the Callander Group for Scotland's Rock Art Project.

Patriotic jewelry - ring
Women's ring with a very original coffin shape with a snap lid. In its center, on a hinge, there is a figure of a January insurgent with a rifle on his shoulder. After lifting the lid of the coffin, the spring lifts the insurgent. The ring was made during the period of national mourning after the January Uprising and symbolizes the immortal will of Poland to regain independence under the partitions and the revival of the idea of freedom among Poles.

Guerrero Iron Ring-Bolt (2019)
Detail of an iron ring-bolt as it was found in 2019 on the shipwreck site 2-04/8MO02343 thought to be that of the 1827 pirate slave ship *Guerrero*. An iron ring is attached to what appears to be the broken shaft of a bolt. The shaft is narrowed, flattened, and folded-over to hold the ring in place.This piece is part of the larger deposit called Iron Objects Feature No.1, found along the east side of the site (see https://skfb.ly/6SBIN). Model created June, 2019. Scale = 10 centimeters. Source: Objaverse 1.0 / Sketchfab

Over Glenny 9 - Cup & Ring Marked Rock
Over Glenny 9 (NN 37032 02897) is in the Menteith Hills north of the Lake of Menteith and is one of the many rock panels in this small area. I was struck by its similarity to the Blarnaboard 1 outcrop on the same sandstone rock formation, the Ruchill Flagstone but some 8km away near Gartmore. This is not a particularly good model & I intend to return to do make a better job of things. Although the cup marks can be shown clearly, the model does not bring out the rings around them at all well. The central group has quite an intricate arrangement of rings withon it and above the 4 to the right are another 3 cup marks that are enclosed within a single, rather distorted, ring which I neglected uncover - it was just a quick evening recce!

Cloanlawers 4 - Cup & Ring Marked Stone
This very weathered stone lies on the 400 metre contour on a SE facing slope above Loch Tay beneath Meall Greigh. It is made of schist and has a residual cup and ring mark and a seperate cup mark on its surface with another possible cup mark. There are a number of further depressions in the rock surface that may be highly weather-out relict cup marks although more likely natural.
