Approaches to testing in software engineering
Selivanov P.A., Kucher M.Yu., Belov Yu.S., Bauman Moscow State Technical University (Kaluga Branch) Kaluga, e-mail: firstname.lastname@example.org
Abstract: This article provides information about the importance of application testing during software development. It is necessary in order to find errors and improve the software and is carried out to reduce risks, as the search and Troubleshooting occurs in advance. It will also consider two qualities of the error that affect the evaluation of the application by its user. The article also describes some testing methods, such as white box and black box testing, their advantages and disadvantages, as well as automated regression testing. The following process will describe the testing, which consists of 4 steps: test plan development, test development, test creation and execution, and results registration. Each stage will contain an explanation. Then the question of testing in agile teams is discussed, that is, how important it is for them and how it should be implemented in this method of development organization. At the end, we will talk about the Postman application, which is used to run tests to the API, what types of variables exist in it, how it works and the advantages of it.
Keywords: regression testing, automated testing, agile testing, API testing, Postman.

Abstract: Presented article is devoted to the question of translating texts in natural language. Within this scientific field, an expert system translating initial natural language queries into relational database queries was developed. An algorithm of receiving the result query and system limitations are described. A description of developed algorithm for generating distributional semantics-based semantic web is described.
Keywords: natural language, distibutional semantics, Prolog, semantic web, term-document matrix, query translation.
Investigation of the spectrum and resolvent of a 4th order differential beam with a threefold characteristic root

Aliev S.A., Nakhichevan Institute of Teachers, Department of Advanced Mathematics and Informatics, Senior Lecturer, Azerbaijan Republic, firstname.lastname@example.org
Abstract: The article is considered that, the spectrum and the resolvent of a structure of fourth-order differential operators are investigated in space L2(0;∞), when one triple root is the main characteristic polynomial. It is shown that, a beam can have a finite or countable number of eigenvalues in theopen lower and open upper half-planes, and the continuous spectrum fills the entire real axis, where spectral features can be located. It is proved that, the resolvent of a structure is a bounded integral operator, defined on the whole space L2(0;∞), with a Carleman type.
Keywords: spectrum, eigen function, resolvent, ad joint operator, Carleman type.
Conceptual features of IdM-type solutions
Blazhko S.V., Postgraduate, Department of Information Technologies and Computing Systems, Moscow State Technological University "STANKIN", Moscow, email@example.com
Abstract: As part of the production activities, the enterprise IT staff of has to perform many similar operations related to the management of user accounts in information systems. To reduce the time required to perform such operations, staff can develop limited software solutions only to specific systems but not compatible to other systems. Large companies, to manage the life cycle of same-user accounts in various systems, often use identity management or IdM systems. This article considers the features of the functioning, implementation and design of IdM-systems.
Keywords: idm, iam, identity manager, identity management, identity and access management, user account management.
Estimation of progress in the adaptive educational environment

Abstract: Infrastructure of the modern educational environment is adaptive. The corresponding systems of estimation conforming to requirements of adequacy, safety, technological effectiveness, interactivity, mass character, standardization, adaptability, etc. are necessary. In article the problem of estimation of educational achievements of trainees, formations of their rating at adaptive training, testing is considered. The model of estimation, drawing up the rating list is offered
Keywords: control, adaptability, training, testing, trainee, education.
The stability of the distributed automatic control systems with nonlinear delay
Tumanov M.P., Cand. of Techn. Sciences, professor (MIEM HSE), Moscow, email@example.com
Abstract: The article shows that in a typical automatic control system containing a network component, it is possible both to reduce the stability margin due to network lag and, in some cases, to increase this margin. The article deals with typical characteristic equations and their roots are calculated depending on the delay. The results of calculations are confirmed by simulation in Matlab.
Keywords: distributed control system; delay compensation.

Abstract: A formal method for constructing a macromodel of a linear equivalent electrical circuit formed in a uniform coordinate basis is described. The macromodel with the same accuracy, but with the calculation speed increased by several orders of magnitude, can be applied for the same calculations as the original model. The speed of multivariate calculation of frequency characteristics can be increased by building and reducing of a system of linear algebraic equations at each point of the frequency range.
The article was prepared within the framework of the Academic Fund Program at the National Research University Higher School of Economics (HSE) in 2019-2020 (grant № 19-04-005) and by the Russian Academic Excellence Project «5-100».
Keywords: macromodel, equivalent electrical circuit, frequency characteristics.
