  • Realize construction and technical expertise of pools

    The water recreation industry is actively developing. An individual pool at home is also not uncommon for a long time, because everyone wants to live in comfortable conditions. Modern country houses place the pool on the ground floor of the premises on the plot next to the house. Despite the financial costs and time for maintenance, the health benefits of the pool, as well as the variety of leisure activities through taking water procedures or playing with children, are a very powerful argument in order to arrange a pool at home.The number of pools is increasing and the number of pools built with defects is also increasing. it may be because use low-quality construction materials and reduce their volumes, perform work by unskilled employees, violate the requirements of construction documents of the project. therefore it is necessary to carry out construction and technical examination.

  • On the issue of calculating the steady-state modes of electric power systems

    When determining the locations of compensating devices, it is necessary to make complex calculations that take into account various factors (included in the equations in the form of variables). To get results, calculations are performed repeatedly. Newton's method with coefficients in the form of a Jacobi matrix is widely used. An algorithm for solving the necessary equations by the Gauss method is considered, and the required number of iterations is determined to obtain reliable results.

  • Development of a methodology for constructing a fault-tolerant authentication system for low-orbit satellites operating in a polynomial system of residue classes

    One of the effective ways to increase the information secrecy of a constellation of low-orbit spacecraft (LVS) is the use of a satellite authentication system (SAS). In order to reduce the time spent on determining the status of the satellite, as well as to increase the fault tolerance of the identification system, in a number of works it is proposed to use the codes of the polynomial system of residue classes (PSCS). This paper presents a methodology for constructing a fault-tolerant authentication system for a spacecraft, which is based on exchange operations implemented in PSKV codes. Using exchange operations, that is, changing the number of informational and redundant bases, it is possible to ensure the possibility of maintaining the operational state of the identification system in the event of a sequence of failures, as a result of which the level of information secrecy of the NSA will not be reduced.

  • SDR study stand

    Soft Defined Radio (SDR) or a software-configurable receiver is the most promising direction for the development of modern radio receivers. Therefore, the study of the principles of its construction should be given special attention in the training of radio engineers. However, since most of the operations for processing and converting the received signal are carried out in software, including in signal processors, the construction of a laboratory layout that is easy to understand raises questions. In this paper, for the greatest coverage of all the processes of processing and converting the received signal, it is proposed that the laboratory model be implemented on the basis of the superheterodyne receiver model with double frequency conversion with a nonzero intermediate frequency. The result is the ability to study the impact of software settings and the adjustment of the parameters of individual structural elements of the circuit (model), as well as the types of individual elements.

  • Increasing the reliability of threshold data separation schemes

    The paper discusses the use of threshold data separation schemes, as one of the promising areas of protection of both private and commercial information. In such schemes, parts of information are distributed among spatially distributed data storages, and information recovery is possible using at least one of the parts. The main disadvantage of such schemes is that they can be easily compromised, for example, if any part of the data is lost, or if the data is falsified by an intruder, it is impossible to localize the error, and, therefore, restore the original information. To solve this disadvantage, it is proposed to use schemes based on the system of residual classes [1] (RNS). The use of data separation algorithms based on the RNS will lead to a decrease in computational complexity, and, consequently, to a decrease in the load on data transmission media. Another advantage of SOCs is that they have corrective properties. A proportional increase in the number of information and redundant modules when using classical data separation schemes will lead to a sharp decrease in the reliability of the entire data exchange scheme. To solve this disadvantage, it is proposed to divide the information into groups, and then distribute it among the participants in the data exchange scheme.

  • Comparative analysis of the emotional perception of friendship between students of Grozny and Rostov-on-Don Part I

    The work is based on experimental results obtained by a survey among students of Grozny and Rostov-on-Don. The affective component of students ' attitudes towards friendship was determined by the technology of semantic differential Ch. Osgood. The distribution functions of the respondents ' emotional attitude to virtual and real friendship, calculated in the framework of a previously developed nonlinear stochastic model, are presented. The results of the comparative analysis show that in the group as a whole, the difference in the perception of real friendship between the respondents of both cities is small. On average, Grozny residents are a little more positive about real friendship. Students of both studied samples perceive virtual friendship in general more negatively than real friendship. But here the difference in relations is more significant. Subgroups with a positive perception in Grozny are about 10% less. On average, Grozny residents are more negative about virtual friendship than Rostov residents. Most likely, this is due to a difference in mentality.

  • The dependence of the bearing capacity on the class of concrete on the example of flexible reinforced concrete columns with combined reinforcement

    The search for the most efficient and cost-effective materials and structures is an important and urgent task. Reducing steel consumption can significantly affect the cost of structures, and the use of high-strength steel is one such method. Currently, there is great interest in reinforced concrete structures, which contain various combinations of pre-compressed, pre-tensioned and non-tensioned reinforcement. To determine the dependence of the bearing capacity on the class of concrete using the example of flexible reinforced concrete columns with combined reinforcement, a numerical experiment was performed. The performed numerical experiment showed the feasibility of using combined reinforcement - all the racks considered in the experiment with combined reinforcement are more effective than racks with non-tensioned reinforcement. At the same time, depending on the relative eccentricity of external forces and flexibility, it is necessary to choose the most effective type of combined reinforcement.

  • Anisotropy of the strength properties of a cement stone at its short-term loading at early age

    Increased concrete strength due to early loading is one of the priorities of concrete technology. Many articles contain data on changes in compressive strength after early loading. The first person to test early concrete loading was Satalkin. He tested bridge supports for static and dynamic loads. The results of his work became the basis for further research in the field of early loading of concrete. The objective of this work is to study the tensile strength in bending after early loading and to check the influence of the orientation of the samples under load. Also we considered the effect of active mineral additives on this parameter. The object of study is samples of cement-sand dough prepared on a Portland cement binder of various manufacturers. We noted a difference in the strength characteristics in bending by changing the orientation of the samples when testing them after early loading. The maximum increment of strength is noted in a plane perpendicular to the direction of compressive force. The use of a mineral additive with the replacement of a fraction of cement gave the attenuation of the observed effect.

  • Determination of intensity of movement of motor roads of local importance, located on the Factory highway in Samara

    The problem of major repairs on the factory highway in Samara still remains unresolved, although the issue has been acute for many years. During this time, as statistics show, there were a lot of accidents and damage to vehicles. A heavy load on the roadbed leads to rapid wear of the asphalt surface, as a result, almost every year the Factory highway needs repairs. The load on the highway will increase even more when the section of road connecting the new Kirovsky bridge with the Zavodsky highway is built. The automobile road in Samara along the ZAVODSKOE highway needs major repairs for several years, but the work does not begin, and every spring its condition worsens more and more. The issue remains relevant today.
