| Аннотация: | The article deals with the problems of mapping Petri nets to the system and functional architectures of distributed computing systems at the middleware level. In particular, the problem of mapping Petri nets to the TCP/IP network is solved experimentally. The need to solve this problem came from the fact that various methods for mapping algorithms to the architecture of parallel and distributed computing systems are known, but only a few of them are oriented to the development of middleware. The importance of the problem is explained by the fact that the definition of middleware overlaps with many existing technologies, such as Cloud Computing, Grid Computing, Utility Computing, Services Computing, and Distributed Computing in general. It is shown that different interpretations of its work for the same Petri net can be used, which significantly affect the quality of the middleware class network software. An example and detailed comments for the distributed Java program are given. | |

| Аннотация: | The anomaly P is a widespread morphological anomaly, which occurs in some groups of amphibians, caused by the trematode parasite Strigea robusta (Digenea: Strigeidae). This anomaly has been previously recorded in water frogs of the genus Pelophylax and toads of the genera Bufo and Bufotes. The anomaly P includes symmetrical polydactyly cases as a mild attenuated form of the complex syndrome, which in severe cases includes strong deformations of hindlimbs and forelimbs. Strigea robusta has a complex 3-host life cycle using planorbid mollusks as the first intermediate hosts, amphibian larvae as the second intermediate hosts, and anatid birds as the definitive hosts. Herein, we described new records of the anomaly P syndrome in water frogs of the genus Pelophylax from the northeastern parts of their ranges. Symmetrical polydactyly (as a mild form of the anomaly P syndrome) was found in 30 individuals of three species of water frogs from seven localities: in 25 individuals of P. lessonae from four waterbodies, in four individuals of P. ridibundus from three waterbodies, and one individual of P. esculentus. In Gusevo pond, three individuals of P. lessonae with severe cases of the syndrome were found. This is the first record of the anomaly P in reliably identified hybridogenetic edible frogs (P. esculentus) that have been identified in nature. Additionally, we provided new data about the occurrence of the anomaly P and the prevalence of the trematode S. robusta in mollusks taken from two water bodies where anomalous water frogs were found. | |

| Аннотация: | Profiled joints of parts (PJ), in which the transfer of the operational load occurs by means of force closure of surfaces, are quite widely used in mechanical engineering. An alternative type of joint is a joint with a guaranteed tension (IFJ), which transmit the load by frictionally closing the mating surfaces of the parts. Such a joint combines the advantages of PJ and IFJ is a spiral friction-profile joint (SFPJ). It joins parts with spiral profile of mating surfaces. The properties of the spiral connection of parts are practically not studied, and there is no methodology for its design and the corresponding regulatory documentation. This article examines the influence of the design parameters and technological factors on the functional properties and stress–strain state of the SFPJ. Analytical methods are used, as well as the finite element method in computer modeling. The design parameters influencing the nominal area parts’ contact are found. The irregularity in the distribution of the equivalent tensions in the contact area is found. The technological factors which are necessary to control in order to provide SFPJ functional properties are found. The spiral friction-profile joint can effectively replace spline, keyed, pinned, profiled joints, tension joints and other fixed connections. | |

| Аннотация: | The article describes an information and analytical platform for collecting and processing big data for the study of innovative development processes of the constituent entities of the Russian Federation. The toolkit of the platform solves the problem of searching, collecting, processing and downloading data from the Internet for the analysis and prognostic modeling of innovation indicators of economic agents in the region. The results are used to assess the dynamics of changes in the innovative development of enterprises and the region as a whole. The objectives of the research are to select leaders who actively develop and implement innovations, benchmarking analysis of regional enterprises with leaders, develop recommendations for managing innovative development mechanisms, and increase the efficiency of innovative activities of enterprises in the region. It is proposed to create a set of tools for analytic processing of big data in the form of a convergent platform with horizontal scaling. To perform the procedures of loading large data into the cloud storage, the streaming architecture of the data search and integration subsystem is implemented with the possibility of parallel preprocessing of information. The components of the information and analytical platform have been developed and implemented | |

| Аннотация: | The article presents new solutions for designing the equipment for final processing parts with a complex profile of working surface. The said solutions allow a planetary rotation of the part at a small center distance of the mandrel with the workpiece and the spindle of the installation. This solution improves the quality of the working surfaces and reduces energy costs. Materials and Methods. The disadvantage of modern devices for final processing of complex parts is the increased energy consumption and the large axial distance between the part and spindle. These factors reduce the quality of processing and the part range in terms of weight and dimension characteristics. The application of new solutions to change the design of the installation is relevant. When designing a new installation, the center distance between the part and the spindle was reduced. This contributed to the reduction of vibrations, improving the quality of surface treatment and increasing the product range. Results. The calculations to reduce the resistance of the abrasive medium affecting on the surface of the diesel engine turbo-compressor wheel blades confirmed the expediency of the solution. The calculations of the part for deflection by using Solid Works 2016 software were carried out. The calculations demonstrated the reliability of the installation when processing parts of medium and large sizes as compared to the basic installation option previously made by Penza State University for Penzadieselmash Company. Conclusions. The calculations made it possible to find that the reduction of the center distance reduces the deflection of parts and vibration in the process of finishing and allows stabilizing the quality and performance of processing the surfaces of a complex profile with less energy coast. A new design of the installation was developed and manufactured. It contributes to planetary rotation of the part at a small axial distance of the mandrel with the part and the spindle of the device. | |

| Аннотация: | Among the known eight-dimensional Thurston geometries, there is a geometry of the Sol manifold – a Lie group consisting of real special matrices. For a left-invariant Riemannian metric on the Sol manifold, the left shift group is a maximal simple transitive group of isometry. In this paper, we found all left-invariant differential 1-forms and proved that on the oriented Sol manifold there is only one left-invariant differential 1-form, such that this form and the left-invariant Riemannian metric together define the contact metric structure on the Sol manifold. We identified all left-invariant contact metric connections and distinguished flat connections among them. A completely non-holonomic contact distribution along with the restriction of a Riemannian metric to this distribution define the contact metric structure on the Sol manifold, and an orthogonal projection of the Levi-Chivita connection is a truncated con-nection. We obtained geodesic parameter equations of the truncated connection, which are the sub-geodesic equations, using a non-holonomic field of frames adapted to the contact metric structure. We revealed that these geodesics are a part of the geodesics of the flat contact metric connection. © 2020, Kazan Federal University. All rights reserved. | |
