For coarse-grained specimens, we are able to compare texture of the specimen and the spatial distribution of luminescence.
Micro-CT uses X-ray attenuation data acquired at multiple viewing angles to reconstruct a 3D representation of the imaged specimen, characterising the spatial distribution of the material density [8, 9].
Depending on the specific specimen size, the spatial flaw distribution may follow either the Poisson postulates or the uniform law, while the strength distribution of concrete does not necessarily always follow the Weibull statistics.
When both a BCS specimen margin was defined as a "positive" margin or as a "close" margin and one or more of the standardized re-resection margin specimens was defined as "positive", the spatial location of these findings were evaluated to assess concordance versus disconcordance of these findings.
MRI scan parameters of the clinical fetal post-mortem MRI were transformed to optimise the spatial resolution of the specimens as they had stayed in a 4% formaldehyde solution for 50 60 years [15, 16].
A specimen of insulating media contains numerous voids, the spatial distribution of which strongly affects the physical properties of the material, such as thermal conductivity and strength.
Since we use a relatively large PH diameter of 3 µm (to keep the design simple and compact by avoiding any light-coupling components), this aperture function is convolved with the spatial features of the specimen.
Corresponding to the rather marginal, solvent-dependent differences in shrinkage, the spatial dimensions of BC specimen were largely preserved throughout loading and precipitation of PLA, CA and PMMA, and during scCO2 drying of the BC/PLA, BC/CA and BC/PMMA hybrid organogels, in particular for those variants with low polymer concentration in the loading baths.
The Cartesian coordinates were exported as ASCII-file and imported to Microsoft Excel to calculate the spatial orientation of each ammonoid specimen (Fig. 4 and Table 1).
To quantitatively describe the spatial distribution of voids in the specimen, probability functions such as two-point correlation, lineal-path, and two-point cluster functions are adopted.
