Creation of a three-dimensional model of the municipality based on data from digital surveys for the purpose of modernizing the work of administration units involved in its land management

D.A. Gura, G.G. Shevchenko, I.G. Markovsky

Digitalization of the economy is an important task for the coming years, set by the Russian president. Digital research is an integral part of bringing old and new information on various sectors of the economy into digital form. This project presents the concept of implementing a laser scanning complex (air, land and mobile) to obtain extensive data on the infrastructure of a single municipality in order to identify violations of the use of land for various purposes. The main final source of information for determining offenses in various areas of life of the city will be its three-dimensional model, compiled from data from digital surveys. The novelty of such a project is that the municipality, periodically carrying out such research, will be able to effectively combat various violations of the use of lands under its control and prevent them at the stage of “origin”.

Collision prevention system and motion safety

T.A. Romanova, M.S. Nikitina, I.G. Markovskiy, I.S. Gribkova

In this paper, a system of preventing collisions of machines when working in mines is considered. Studies have shown that the criterion for the functioning of a collision avoidance system is the safety distance to the object. ATP is also designed for mines operating under extreme conditions. The peculiarity is that the use of identical components on all equipment facilitates maintenance and logistics. Details are painted collision avoidance scheme with the help of ATP. The problems of collisions and their solutions are considered. By incorporating a TopView display into the ATP, we have an improved signaling algorithm that improves situational awareness and reduces the number of false warnings. A significant feature of the ATP is the presence of a black box.

To the question of foreign language education modelling in a modern non-linguistic university

O.N. Likhacheva

Educational process modelling is an important component in modern Pedagogical science. This actual method implies building a certain model, a hypothetical scheme of an activity or phenomenon created for finding out hidden sides or properties which can’t be defined by means of direct studying of the above mentioned aspects. The English language is indispensible in modern conditions as an effective instrument of professional and personal development. Educational process modelling in this context helps to foresee its effective development and functioning that will finally have a positive result.

Aspects of modelling a foreign language educational process in a non-linguistic university

O.N. Likhacheva

The problem of modelling in Pedagogics is an interesting sphere of research characterized not only by a theoretical aspect which widens the specter of a modern research apparatus but has practical recommendations facilitating the educational process improvement. This article deals with the preparation for modelling teaching a foreign language process in the frame of a modern non-linguistic university. For constructing the integrated and effective model of a foreign language education in modern conditions, we confirm its definitions in the context of this research; make classifications of pedagogical process participants according to such criteria as motivation, ability to research and professional characteristics. Such aspect as pedagogical interaction is characterized as well. These classifications will help define the direction of pedagogical modeling in the future, and that will facilitate the development of a foreign language communicative competence by a modern non-linguistic student.

A comparative analysis of estimated activity in Russia, the Czech Republic and Italy

M.A. Pastukhov, O.I. Pastukhova, A.S. Sukmanuk

With the development of a market economy and private property in the world society, there was a need for a fair estimation of it. On this basis, there was a need for the formation of organizations that regulate and implement an independent valuation of property. There appeared a large number of situations where valuation was needed, such as buying and selling, renting, insurance, liquidation, privatization, calculation of taxes, duties and other types of operations. The system of estimation activity has been formed, including the process of professional valuation performed by a qualified valuer, and a scientific discipline with certain concepts, research principles, methods and approaches to valuing movable and immovable property. In each country, where the valuation is relevant, there is an individual system of valuation activity. The research was based on Russia, the Czech Republic and Italy. Due to the differences in the economies of these countries, it should be assumed that the regulation and organization of valuation activities has a number of characteristics that need to be studied. As a result of the analysis of various sources, which describe the provisions on the estimation activity of Russia, the Czech Republic and Italy, a number of features of regulation and organization have emerged.

Keywords: appraisal activity, evaluation standards, self-regulating organizations, state regulation, subjects of valuation activity, reporting documentation (evaluation report), evaluation areas.

Scientists of social and humanitarian Sciences are engaged in the problem of formation of the student’s personality. The authors analyze this problem from the standpoint of sociological science. In the process of becoming a person at the University, the student goes through three stages: adaptation, individualization and integration. The authors come to the conclusion that the environment of the higher educational institution contains all the necessary conditions for the full formation of the personality of students, namely the conditions for meeting the needs of the interests of individuals in communication, education, acquisition of a new social status. The environment of the University acts as a set of elements that affect the process of individualization and integration of students. In the process of studying at the University, the student acquires new knowledge, new value orientations are formed.

Features of behavior of entrants as consumers in the market of educational services

T.N. Chunikhina, A.E. Krylova

This article discusses the behavior of students as consumers of educational services. The authors analyze sociological approaches to the definition of «educational service». Summarizing the considered approaches to the definition of «educational service», it is concluded that it is one of the varieties of services that are provided in the process of education. Therefore, consumers of education can be both individuals and organizations, the state, but the final consumer of educational services is always a person-an applicant, a student, a listener, an employee, etc. The purpose of the article is to consider the peculiarities of behavior of applicants as the most numerous group of consumers of educational services. The authors define the main features of behavior of entrants as consumers of educational services. As a feature of consumer behavior of applicants, the authors highlight: the need to predict the effectiveness of choice for several years to come; the possibility of acquiring educational services in a certain period of time; the choice of those educational institutions whose services are more accessible to them; lack of independence of decision making due to age.

Nomogram of monitoring and predicting sugar losses with pulp during the processing of sugar beet

S.O. Semenikhin, N.I. Kotlyarevskaya, M.M. Usmanov

The theoretical description of counterflow diffusion desugarization of beet cossettes was done over 50 years ago, when it was believed that the return of press water adversely affects the quality of the raw juice. However, with the growth of technological progress and the commissioning of more efficient diffusion apparatus and pulp presses transition to return press water, formation in the production of which was up to 50 % by beet, required the introduction of revisions to the classical theory. The article presents the equation of the mass transfer process in the diffusion apparatus, which takes into account the return of pulp press water and the partial pressing of cossettes in the process of desugarization, as well as the equation that corrects the volume of the returned pulp press water, depending on the degree of pressing of the desugared cossettes. For convenience, on the basis of these equations, a nomogram of operation of continuous-action diffusion apparatus was derived, the method of its practical use is also given in the article.
