Overview and testing of speech recognition systems
Resumo
This article describes and compares the characteristics of such most common speech recognition systems as CMU Sphinx, Google Speech, HTK, Julius, iAtros, RWTH ASR. The comparison is based on the following important characteristics: supported recognition languages, supported operating systems, availability of documentation, open source code, presence or absence of offline mode, WER, WRR, SF indicators. It also describes the process and results of testing the best systems for various indicators.
New double-sided bounds for complete elliptic integrals of the first and the second kinds
Resumo
Two theorems are proved in this paper, in which lower and upper bounds are established for complete elliptic integrals of the first and second kind, expressed in terms of elementary functions. These theorems are applied to a model geometric example. In addition, the article presents graphs of dependencies on the modulus of these integrals of both the estimates obtained and their relative errors. The applicability of the approximations found for technical applications is also discussed.
Development of software for a specialized electric power meter with remote information transmission
Resumo
The article contains a description of the process of developing a web application for displaying information received from a specialized electricity meter with remote transmission of information. There are demonstrated the main stages of creating a web application: setting the problem, designing, prototyping, software implementation of the created layout and testing.

Development of a system for automatic chord sequence recognition in digital audio files
Resumo
The article considers an algorithm for recognizing a chord sequence in audio files by dividing the frequencies of notes into frequency classes. The principles of operation and implementation of the system developed by the authors based on this algorithm are described.
Modeling the production structure optimization process
Resumo
The problem of constructing a mathematical model for calculating the optimal structure of output and the structure of prices supporting the maximum rate of growth of production is considered in the article. The optimal trajectory of economic growth in production is defined as a long-term state of equilibrium in the market.
Organization of the process of automated testing of web applications based on the selenium framework
Resumo
The article describes a software system developed by the authors that allows automated testing of web applications based on the SELENIUM framework. The architecture of the software system is considered in detail, the process of building test scenarios and generating reports on the conducted testing is described, an example of testing a specific web application is given.
Investigation of forced vibrations of a linear system with two degrees of freedom and a small parameter by the lyapunov-schmidt method
Resumo
The article is devoted to finding periodic solutions to linear systems with two degrees of freedom and a small parameter by the Lyapunov-Schmidt method. On the basis of the Lyapunov-Schmidt method, an algorithm was developed in the Maple package, graphs of the components of periodic solutions and phase trajectories of the disturbed system were constructed.
