![]() With the Burton-Prim-Slichter theory, the equilibrium distribution coefficients can be calculated. The effective distribution coefficients for Nd(exp 3+), Sm(exp 3+) and Er(sup 3+) as dopants are determined experimentally as a function of the crystal growth velocity. Sample data were generated on the basis of the common factor model and…ĭistribution coefficients of rare earth ions in cubic zirconium dioxideĬubic zirconium dioxide crystals are grown with the skull melting technique. The effects of sample size, number of variables, and population value of the congruence coefficient on the sampling distribution of the congruence coefficient were examined. ![]() This study developed and investigated an empirical sampling distribution of the congruence coefficient. Adopting the methodology known as Procrustes, the data table was thus progressively reduced, and each time investigated: the results so obtained were then used to reach a global assessment about how much each reduced data set could correspond to the optimized one.An Investigation of the Sampling Distribution of the Congruence Coefficient.ĮRIC Educational Resources Information Centerīroadbooks, Wendy J. For this reason, looking for an optimal composition and for the most effective encoding of the data set, a reduction of its rarest forms was performed to find the threshold which could allow to reconcile the need for keeping the useful encoded information with the best possible reduction of elements producing high inertia. The presence of a relatively high number of rare forms in the data set – besides the hapax – led to think, however, that the extraction of the factors – so the outcomes of the analyses – could have been influenced heavily by them. The use of Textual Correspondence Analysis to investigate a corpus of iconographic compositions carved on Mesopotamian cylinder seals proved to be very useful to understand the peculiarities of the specimens from the points of view of geographic origin, typology and inner chronology. The cooperation of archaeologists and engineers in the development of the Phaistos game ensures a gaming experience not only pleasant but also provided with a strong educational profile. ![]() The virtual environment thus realized constituted an ideal starting point for the development of an educational fruition project based on a Serious Game approach. The lack of accessibility of the South-Western Quarter of Phaistos Palace to the visitors attributes a special interest to this output. ![]() Furthermore, the research has been focused on the opportunity to exploit the obtained virtual model both for scientific purposes and for the outreach. Special attention was addressed to the comparison of the two datasets and to the reuse of the first one for georeferencing and scaling the second one. Starting from the point cloud by laser scanner, the most recent, low cost and user-friendly photogrammetric tools (GoPro camera and software Agisoft Metashape) have been used during the 2019 campaign in order to update and to improve the previous dataset, which was used as a grid for georeferencing and scaling the new virtual model. The article focuses on two digital survey campaigns carried out respectively in 2014, laser scanning, and 2019, Structure from Motion. The article presents the results of a wider research carried out by a multidisciplinary group (archaeologists and engineers) of the University and the CNR-ISPC of Catania in the South-Western Quarter of the Minoan Palace of Phaistos (Crete). ![]()
