In this paper, developing the early proposed unified approach to the representation of morphological models, we show that since morphological models in the attribute representation have the same mathematical form as images, the morphological models themselves can be the subject of morphological analysis and can be directly compared in form with using morphological operators. In this case, the previously introduced formalism of mosaic diffusion morphology is used.In the framework of mosaic diffusion morphology, two alternative descriptions of the projection of the image on the form are considered, which are based on a clear model and a fuzzy model of the form respectively. It is shown that the projection operator in the second case is a one-sorted diffuse operator that makes direct comparision of model to model instead of image to model. In this case, a fuzzy mosaic model appears in this scheme as a projection of a clear mosaic model onto another clear mosaic model. Based on this shape-to-shape projection idea, we propose the new version of Pytiev morphology tools for shape comparison: the morphological shape difference map, the morphological quasi-distance between shapes, as well as the Morphological Shape Correlation Coefficient (MSCC). We show that MSCC from the resource parameters of the reciprocal model has exactly the same formula as the standard effective morphological correlation coefficient proposed earlier based on statistical averaging of projected images.

Abstract. A lot of image matching applications require image comparison to be invariant relative to intensity values variations. The Pyt’ev theory for Morphological Image Analysis (MIA) was developed based on image-to-shape matching with mosaic shape models. Within the framework of this theory, the problem of shape-to-shape comparison was previously considered too. The most sophisticated and weakest part of MIA theory is the comparison of mosaic shapes with some arbitrary restrictions described by graphs or relations. In this paper we consider the possible options for comparing images and shapes using morphological projection and morphological correlation. Our contribution is a new scheme of morphological shape-to-image projection and, correspondingly, the new morphological correlation coefficient (MCC) for shape-to-image correlation with restricted mosaic models. We also refine the expressions for shape-to-shape comparison.

Purpose:To evaluate the intrasubject repeatability of the ocular aberrometry obtained with a new ocular pyramidal aberrometer technology in a sample of normal eyes.Methods:A total of 53 healthy eyes of 53 subjects with ages ranging from 18 to 45 years were included in this study. In all cases, three consecutive acquisitions were obtained. Intrasubject repeatability of the measurements with a pyramidal aberrometer was calculated. Intrasubject repeatability for 4.0- and 6.0-mm pupils was evaluated within the subject standard deviation (Sw) and intraclass correlation coefficient.Results:Low values of the Swand intraclass correlation coefficient outcomes close to 1 were observed for the sphere and cylinder at 3.0-mm pupil size. Most low Swand intraclass correlation coefficient values close to 1 were observed for total, low-order aberrations and higher-order aberrations root mean square and for each Zernike coefficient analysis (intraclass correlation coefficient ⩾0.798) at 4.0-mm pupil size, with more limited outcomes for the aberrometric coefficient of Z(4, 4) with an intraclass correlation coefficient of 0.683. For a 6.0 mm pupil diameter, low Swand intraclass correlation coefficient values close to 1 were observed for all aberrometric parameters or Zernike coefficients analyzed (intraclass correlation coefficient ⩾0.850).Conclusion:The new pyramidal aberrometer Osiris provides repeatable and consistent measurements of ocular aberrometry measurements in normal eyes.

Introduction. The article is devoted to the description of pottery ceramics on Mordovian territory. The purpose of the article is to analyze the development of ceramics in Mordovian region. The object of the article is a collection of ceramics of Mordovian republican S.D. Erzia Fine Art Museum, the subject – the main features of the ceramics based on the morphological analysis of its exhibits. Materials and Methods. The material of the study was the results of the research of Russian scholars on ceramics of antiquity and modernity, as well as empirical materials presented by the ceramics funds of Mordovian republican S.D. Erzia Fine Art Museum. One of the main approaches implemented in the article is a comparative analysis of the exhibits based on the color of the shard. It allows the author to systematize utensils according to their functional purpose, and also to make an assumption about the various historical stages of the emergence of different types. Results and Discussion. The article systematizes the variety of forms of ceramics, reveals their quantitative relationships, the prevailing forms, and gives the comparative analysis of the existing forms. The classification of vessels was carried out in accordance with a number of criteria: the height and thickness of the neck, the design of the corolla cut, the diameter of the mouth and the maximum extension of the trunk, which allows one to draw conclusions about the similarity of the collection’s exhibits with other Mordоvian artefacts. Conclusion. It concludes about the existence of a certain standard in the production of ceramic dishes, and on the similarity of the studied ceramics and the collections of Russian monuments. Therefore, it states the preservation of local Mordovian pottery traditions in the course of wide interactions with Russian pottery ceramics.

Whenever two or more raters evaluate a patient or student, it may be necessary to determine the degree to which they assign the same label or rating to the subject. The major problem in deciding which statistic to use is the plethora of different techniques which are available. This paper reviews some of the more commonly used techniques, such as Raw Agreement, Cohen's kappa and weighted kappa, and shows that, in most circumstances, they can all be replaced by the intraclass correlation coefficient (ICC). This paper also shows how the ICC can be used in situations where the other statistics cannot be used and how to select the best subset of raters.

Substructures coupling is still an important tool in several applications of modal analysis, especially structural modification and structures assembling. The subject is particularly relevant in virtual prototyping of complex systems and responds to actual industrial needs. This paper analyzes the possibility of assembling together different substructures' models. The important role of rotational DoFs is highlighted, underlying the difficulty of assembling theoretical and experimental models, for which, usually, the rotational DoFs are not available. Expansion techniques can be used to provide this information as well as appropriate modelling of joints. With this information FRF models, modal models and FE models can be appropriately combined together and solutions for several cases of practical interest are presented. The analyzed procedures are tested on purpose-built benchmarks, showing limits and capabilities of each of them.

 Background: Identification is the act of establishing the identity of an individual. This is a dynamic process and human remains in form of bones can serve as an excellent tool for establishing the sexual identity of the deceased, along with other methods such as DNA, fingerprints, blood group identification etc. Metric analysis of various bones can serve as a viable alternative in cases when morphological analysis is not possible due to damage to the skeletal remains or as an additive analytical tool to establish a positive identity.Methods: Metric analysis of various parameters of randomly selected 100 pairs of human talus bones (50 male and 50 female) as a means of establishing sexual identity from skeletal remains obtained from unidentified and unclaimed dead bodies brought for autopsy.Results: In the present study we found that the values of all the various dimensions measured were higher among the male subjects as compared to that in female samples as was expected. On further analysis, this difference was found to be statistically significant (p<0.001). For the right sided and left sided talus bone, the probable accuracy for various parameters ranged between 83.3% to 100% each, thus indicating strong correlation between sex of the subject and various measurements.Conclusions: The tarsal and their dimensions are highly sexually dimorphic and are useful in determining sex in individuals of this region.

Problem setting. One of the basic human rights, enshrined in the Constitution of Ukraine, is the right to inviolability of housing or other possession. The Basic Law stipulates that no penetration into a home or other possession of a person, inspection or search in them is allowed differently than according to a motivated court decision. This provision means that the state is authorized to reasonably restrict the above law. However, according to law enforcement practice, such restriction of the right to inviolability of housing or other possession is not always reasonable and there is an unequal and improper application of regulatory provisions regulating the procedure for carrying out this investigative (investigative) action. This, in turn, requires a comprehensive analysis of problematic issues that arise during the search and a unified approach to their solution. The object of research is legal relations arising during a search of housing or other possession of a person. The subject of the study are regulations that regulate the grounds, conditions and procedural procedure for conducting a search of housing or other possession of a person. Analysis of recent researches and publications. In the scientific literature, certain aspects of the search of housing or other possession were the subject of scientific research of such scientists as: V. Goncharenko, I. Hlovyuk, V. Zaborovsky, V. Noor, O. Kaplina, O. Komarnytska, O. Shvykova, M. Shumylo etc. Target of research is to study problematic issues arising during the search of housing or other possession of a person and to develop on its basis proposals for improving the current criminal procedural legislation. The scientific novelty of the research is to express proposals for improving the current criminal procedural legislation, which relate to the procedural procedure for the search of housing or other possession of a person, the announcement of a break in its conduct and the peculiarities of fixing its results. Article’s main body. The scientific research is devoted to the analysis of the grounds, conditions and procedural procedure for conducting a search in a dwelling or other possession of a person, guarantees of protection of the rights and freedoms of a person during this investigative (search) action, features of fixing the course of conducting a search of a home or other possession of a person. Conclusions and prospects for the development. Based on the analysis, we conclude that it is appropriate to apply to the decision of the Supreme Court of 02.09.2020. № 591/4742/16-k, which states that the protocol of the search of housing is unacceptable evidence, if it does not contain information about the employees of the operational units involved in it, the sequence of all actions during the search and packaging of seized items, as well as if during the search at the time of detection of equipment intended for the manufacture of narcotic drugs (subject of crime), were not present understood, invited investigators after the discovery of such equipment.

Several successful methods for balancing flexible rotating shells have been developed in recent years. The methods can apparently be subdivided into a group which is based on modal characteristics and another set which employs influence coefficients. The relative merits of these two approaches have been the subject of much discussion and argument — most of it inconclusive and rather fruitless. The authors consider that in practice many of the differences are more apparent than real and that they seem to occur because the various techniques are normally presented in relatively simple and ideal, theoretical terms. This paper represents the start of a joint project which hopes to resolve the apparent differences and, eventually, develop a unified approach to such balancing. A discussion of the theoretical basis for this unified approach is presented along with a description of a test program conducted to explore the possibilities of such an approach.

AbstractThis article seeks to illustrate the kinds of difficulties that may follow from renouncing a unified approach to restitutionary claims for unjust enrichment. To do so, it draws on the experience of the French legal system, where the notion of unjustified enrichment describes a maxim inspiring various doctrines which have evolved in relative isolation from each other. Relying on this experience, the article argues that the objections recently raised by Nils Jansen against the German law of unjustified enrichment should not lead English lawyers to downplay the value of a unified approach to the subject.
