Метод статистической малоракурсной реконструкции геометрических характеристик трехмерных объектов по их дискретным проекционным изображениям.
In this paper the method of statistical few view reconstruction of the geometrical characteristics of three-dimensional convex objects of irregular shape which are approximated by an ellipsoid of General form is under consideration. The statistical reconstruction is carried out with the usage of the basic features of a triad of its mutually orthogonal two-dimensional discrete projection images. The areas of two-dimensional projection images of an object and its linear sizes of one-dimensional projection images are taken as the basic characteristics. While describing an object sizes, we consider that the spatial geometrical characteristics of an object are its linear (dimensional) sizes and the average projected diameter of a three-dimensional image of an ellipsoid of General form, which approximates this object. While describing the object shape, we consider that the spatial geometrical characteristics of an object are represented by the coefficient of asphericity that is determined as the ratio of the maximum and minimum dimensions (axes) of the approximating ellipsoid.
The article shows that the concept of reflection – the basic concept of Cartesian theory of knowledge – determines fundamental difficulties not only of classical conceptions of self-knowledge but also of contemporary conceptions that deny the subject-object relation of self-knowledge. Not declarative but real refusal from reflection as a method of self-knowledge proves to be the key to finding a productive approach to understanding of subjectivity.

In this paper I briefly consider the following questions: 1) the actual ontology of states of affairs as it is given in Plantinga’s semantics; 2) the problem of transworld identity; 3) the redundancy of the concept of «object» as A. Plantinga postulates it. A philosophical analysis of this concept, as well as the concepts of «I» and of «actual world» within the framework of «states of affairs semantics» is provided.
The main object of this paper consists in solving of the inverse problem of optical tomography through the development of a method of dynamical statistical spatial-temporal reconstruction of sizes and shape of moving three-dimensional objects with the usage of their projected images.
The newness of the given method consists in dynamical, few view, spatial-temporal reconstruction of sizes and shape not of a convex three-dimensional object itself, but its adequate approximation represented as a three-dimensional image of the ellipsoid of general form. Along with this, the geometrical sizes of a three-dimensional object are specified by numerical values of the axes of this three-dimensional image of ellipsoid and the average projected diameter of the image (D), and the shape factor (K) is specified by the ratio of the maximum and minimum overall dimensions (axes) of the image of the approximating ellipsoid.
The contours of three discrete, two-dimensional projected images of an object are specified as the optimal form of the primary geometrical information by a simulation modeling method. In this case, their spatial orientation is their mutual orthogonality. Their maximum and minimum overall dimensions are chosen as the optimal basic geometrical characteristics of projected images (the most informative characteristics according to the method of maximal entropy).
The mathematical model of object reconstruction is defined by the functional dependences of linear sizes of three mutually orthogonal axis of the approximating ellipsoid to the maximum and minimum dimensions of its three projected images.
In the result of statistical studies it is determined that the relative error of computing of the average projected diameter of an object is about 0.25% (at the reliability of PD = 0.7 and K = 1,3 relative units). The relative error of computing of form factor of an object is from 2.3% (PK = 0.7 and K = 1.3 relative units) to 0.6% (with PK = 0.96 and K = 1.05 relative units), and the total control time of object sizes and object shape does not exceed 10 Ms.
Thus, the proposed method of dynamic reconstruction has a new combination of characteristics of accuracy, reliability and performance. It has been successfully employed for a high performance, manufacturing, televisional size and form control for elements of the nuclear fuel and can be applied for remote control of various moving convex objects in real-time.
Introduction: efficient legal protection of intellectual outputs is essential for the dynamic development of modern society. The list of intellectual property objects is not intended to be exhaustive, separate outputs lose their relevance and become excluded from the list of protected objects, while new ones, on the contrary, are added to it. Purpose: this work aims to identify the tendencies regarding the extension of the range of intellectual property objects at the beginning of the 21st century, and to define the scientific and technological progress results that were granted protection under the influence of the Fourth Industrial Revolution and other factors. Methods: the method of formal logic, historical, comparative legal, systemic structural and formal dogmatic methods were used in course of the analysis. Results: international legal regulation does not provide clearly-defined guidelines to restrict the sphere of intellectual property. This factor undoubtedly contributes to expanding the list of its objects. At the beginning of the 21st century, law-based lists of copyrighted works did not include any new items. The institute of neighboring rights is most dynamically developing in the Law of the European Union. The Directive on Copyright in the Digital Single Market proposes recognizing two new neighboring rights. One of them is the right of the press publishers for online use of their publications by the news aggregators. The other neighboring right included into the draft Directive was the right to coverage of sporting events. However, in February, 2019, the provisions on this right were excluded from the Directive. In our opinion, biomedical cell products constitute new objects of civil circulation that require their own legal regulation as intellectual property constituents. Conclusions: intellectual property law cannot and should not undergo changes with the emergence of every new kind of objects. The contemporary challenge facing civil jurisprudence and the legislature is to formulate universal regulations that would make it possible to protect the rights of authors and developers of technological solutions even at the stage of experiments.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
The geographic information system (GIS) is based on the first and only Russian Imperial Census of 1897 and the First All-Union Census of the Soviet Union of 1926. The GIS features vector data (shapefiles) of allprovinces of the two states. For the 1897 census, there is information about linguistic, religious, and social estate groups. The part based on the 1926 census features nationality. Both shapefiles include information on gender, rural and urban population. The GIS allows for producing any necessary maps for individual studies of the period which require the administrative boundaries and demographic information.
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
