Investigation of forced oscillations of a linear system of two coupled oscillators with a small parameter
Resumo
The article is devoted to the description of the development of an algorithm for finding periodic solutions of one linear system of two coupled oscillators with a small parameter based on the Lyapunov-Schmidt method. The cases when the frequency of forced oscillations coincides with one of the natural oscillation frequencies are considered. Graphs of periodic solutions and phase trajectories of a system of two coupled oscillators have been constructed.

Development of additional software module for Teamcenter PLM system (Siemens)
Resumo
This article considers the process of creating an add-on software module for the Teamcenter industrial product lifecycle management system, which automates the process of creating the structure of the «Configuration Sheet» document. The authors describe the stages of modeling, design and implementation of this module.
Development of software module for automation of call center quality control department
Resumo
The article describes a software system developed by the authors and designed to automate the quality control department of the call center, specializing in conducting sociological research. The automation process is based on the transcribation service, i.e. translation of an audio file into text.
The Problem of Optimal Economic Growth
Resumo
The problem of optimizing the level of consumption for an economic object on the example of a specific enterprise is considered in the article. On the basis of the maximum principle, the problem of savings optimization is solved. The optimal trajectories of consumption and capital-labor ratio are obtained.
Mathematical model for spread of infectious diseases
Resumo
The article presents a mathematical model for the spread of infectious diseases. The pictures of the dynamics of the spread of diseases for China and Italy were obtained. Forecasting of the epidemic was made, taking into account the data for each country.
Suspension over rough circle transformations
Resumo
The first section of this article presents the basic definitions of the topic, the second chapter focuses on structurally stable circle transformations, and the last chapter is dedicated to suspensions on model transformation of 1. The basic results of the research are theorem 3.1 about equivalence of suspensions on model diffeomorphisms and statement 4.1 that equivalence of suspensions on orientation-reversing diffeomorphisms implies the diffeomorphisms conjugacy.
Realization of the acyclic Smale diagram by an omega-stable surface diffeomorfism
Resumo
Smale diagram of ω-stable diffeomorfism is a graph, which vertices correspond to basic sets and oriented edges sequentially connect vertices of maximal chain. Smale formulated description of acceptable diagrams, which are realized by a diffeomorfism. Present paper proves that an acyclic graph is implemented by an ω-stable diffeomorfism on surface with nontrivial basic sets.
Application of Blockchain Technology for Remote Voting
Resumo
The article presents a software system prototype developed by the authors and designed for making collective decisions by remote voting based on blockchain technology. As a result, both open and secret voting have been implemented. The receipt of reporting documents based on voting results has been automated. It is also possible to generate minutes of meetings, extracts from minutes, etc.
