Dataset for an application example of a unified theory for 3D Gear and Thread Metrology
<p>The evaluation of this dataset is presented in Stein et al. (2021) as an example for the advantages of the suggested novel approach. We propose a unified theory for the metrological treatment of helical machine elements such as cylindrical and conical gears, worms, and screw threads. The main idea is to introduce a universal 3D geometry model for threaded components that provides for distinct parameterization using a unique set of geometry parameters and that offers and a functional description of the transverse profile. Using modern 3D coordinate measuring technology, a holistic evaluation algorithm yields the actual geometry as the result of a high dimensional best-fit procedure and form deviations as corresponding residuals. All determinants and evaluation parameters can then be calculated from the set of actual geometry parameters. By applying certain constraints to the model to be fitted, the novel method can be reduced to the established 2D methods and hence meets demands for the comparison of the two procedures. The results of the novel approach have proven to be very stable and they enable the evaluation of areal measurements with no loss of information.</p>

Figure 4 in Chronic stress from fishing gear entanglement is recorded in baleen from a bowhead whale (Balaena mysticetus)
Figure 4. Glucocorticoid hormone profile in baleen from entangled bowhead whale 17B6. Baleen GC concentrations (ng/g) are shown as red circles for cortisol and orange circles for corticosterone. Sample dates were estimated based on an annual baleen growth rate of 17.5 cm/yr, starting with the harvest date (5 May 2017) on the right side of the bottom x-axis and extending retrospectively to approximately November 2005 on the left side of the x-axis (tick marks are months). Sampling locations along the baleen plate are shown on the top x-axis, and background gridlines represent the 1.25 or 2.5 cm sampling intervals used, starting at the plate base.
Figure 3. The first 10 in Chronic stress from fishing gear entanglement is recorded in baleen from a bowhead whale (Balaena mysticetus)
Figure 3. The first 10 cm of the baleen plate from bowhead whale 17B6 showing a measuring tape attached to the labial margin of the plate to guide sampling intervals. Samples were drilled every 1.25 cm (~26 d intervals) across the horizontal growth lines along the plate for the first 35 cm of growth to maximize the possibility of capturing data on the entanglement event from more recent baleen growth, and every 2.5 cm (~52 d intervals) for the reminder of the plate to establish baseline levels of GCs prior to the entanglement. Samples were collected using a hand-held Dremel rotary tool to produce pulverized baleen powder for glucocorticoid hormone analysis.
Figure 2. Fishing rope recovered from bowhead whale 17B6 in Chronic stress from fishing gear entanglement is recorded in baleen from a bowhead whale (Balaena mysticetus)
Figure 2. Fishing rope recovered from bowhead whale 17B6 included two types of 19 mm diameter rope. Segment (#1) appeared to be white nylon rope, while segments (#s 2, 4, 5) were blue-flecked and most likely a copolymer rope. Segment (#3) was line used by the hunters during the harvest and was not part of the whale entanglement. Fraying of the rope ends was consistent with cut ends that had not been heat sealed or whipped. It was not possible to determine the status of the gear at the time of entanglement.

B-29 Over Exposed Landing Gear
This is a photogrammetry scan of one of the landing gear assemblies from the crash site of Over Exposed, a Boeing RB-29A Superfortress. It was used as a photographic plane and took photos of some of the nuclear tests at Bikini Atoll. Sadly none of the crew members survived the crash.
