The study is aimed at comparing the methods of restoring correspondence matri ces, the traditional transport school and modern mobile technologies. Traditionally, correspondence matrices are restored by interviewing vehicle drivers and applying gravity models (to extrapolate and fill in unobserved movements), then matrix estimation methods are used to calculate traffic flows. Each of these approaches has a number of advantages and disadvantages, but there is no evidence to assess the quality of the data obtained.

The study is aimed at comparing the methods of restoring the correspondence matrices and a more detailed study of the algorithm for restoring the correspondence matrix based on innovative mobile technologies. Previously, the correspondence matrices were reconstructed by interviewing vehicle drivers and applying gravity models, then matrix estimation methods are used to calculate traffic flows. Each of these approaches has a number of advantages and disadvantages, but there is no evidence to assess the quality of the data obtained. The results show that, in general, processing da-ta from the mobile network allows for a more reliable estimate without taking into account survey data or similar observations, and using this type of research can lead to a more consistent assessment of trips with a larger sample size

In this article the various methods of assessment of gas-thermal coating’s adhesion strength are considered. The methodology of carrying out the strength tests, using traditional methods of quantitative assessment of adhesive strength of a coating towards its basement, is reflected; the advantages and disadvantages of the represented methods are given. In the article, the theoretical justification of the mechanics of adhesive avulsion is given, and the imperfection of conic pins’ usage is shown. Aiming at increasing of the accuracy and quality of the strength tests of gas-thermal coatings, a modernised methodology, as well as the samples (а.с.1436025), related to detection of the adhesion strength, are suggested. The theoretical computation of the reasonableness of usage of ring cross section of the coating, resulted in the event of usage of the offered sample, is given. On the basis of theoretical computation, a defining formula of the adhesive strength is conducted. Comparison tests of adhesion strength with various sample’s designs are completed. The reasonableness and effectiveness of usage of the offered methodology in assessment of gas-thermal coating’s adhesion strength are proven.

The paper provides a review of industrial technologies for the production of nuclear zirconium. Their advantages and disadvantages have been shown, a comparative analysis of the quality of zirconium and hafnium salts has been given. Zirconium with a purity of 99.95%, is on a par with the quality of the iodide metal, with a hafnium content of less than 0.005%, was obtained from zirconium tetrafluoride (TFZ) by electrolysis and method of salt recovery with calcium.

Currently, the Russian Federation is implementing the national project «Education», the key goals of which are to ensure the global competitiveness of Russian education and to become one of the top 10 countries in the world in terms of quality of education. The article presents a comparative analysis of the principles of the educational systems of the Soviet and Russian schools. The article describes the key advantages and disadvantages of education in the Soviet era, which was based on ZUN (knowledge, skills). The article reveals the advantages and disadvantages of modern Russian education, the fundamental core of which is UUD (universal educational actions). The article emphasizes that, despite the introduction of the second-generation Federal state educational standards and the introduction of innovative technologies, the level of quality of education in the USSR (the Union of Soviet Socialist Republics) was higher than at present.

One of the most severe complications of metastatic lesion of the skeleton is the development of a pathological fracture, which not only affects the quality of life, makes it difficult to carry out adequate systemic treatment, but also has a negative effect on survival. In case of a pathological fracture, the main method of treatment is a surgical method. The main goal of the correction is to achieve stability and reduce metastatic pain in the area of damage or fracture. Today, the most popular organ-preserving operations for metastatic lesions of the femur in combination with pathological fractures are endoprosthesis and intramedullary osteosynthesis. In this paper, a comparative analysis of the results of their use is carried out, the advantages and disadvantages of each of the methods are described.

Recent years have brought the rise of importance of quality of developed software. Web applications should be functional, user friendly as also efficient. There are many tools available on the market for testing the performance of web applications. To help you choose the right tool, the article compares three of them: Apache JMeter, LoadNinja and Gatling. They were analyzed in terms of a user-friendly interface, parameterization of the requests and creation of own testing scripts. The research was carried out using a specially prepared application. The summary indicates the most important advantages and disadvantages of the selected tools.

Analysis Of Dynamics

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.
