Integration of MatLab and R with high-level languages using C# and Microsoft Visual Studio as an example

The paper discusses the technology of integration (providing a single interface of interaction) of different software systems working in a single environment. The levels of integration are indicated, the composition of subtasks (subsystems), which can be solved efficiently using various computing environments, are highlighted. The expediency of joint use of MatLab and R systems with high-level programming languages C ++ and C # is shown due to the limited or lack of tools for creating a convenient graphical user interface for mathematical systems, as well as the weak adaptability of programming languages for mathematical or statistical data processing and solving modeling problems. The aim of the article is to justify the most appropriate technology for integrating MatLab and R with highlevel programming languages to ensure high interaction efficiency and a user-friendly interface for complex mathematical or statistical data processing problems. The analysis of the possibilities and ways of solving the organization of interaction of MatLab and R systems with high-level languages carried out on the example of C # and the Microsoft Visual Studio environment. The possibilities of interaction of the R system and the MatLab system with highlevel programming languages, respectively, are considered. An example of software implementation of the integration of R and MatLab with a C# application is given. The capabilities of the developed program as a whole and the functionality of each of the subsystems used (R, MatLab and applications in C #) are indicated. The most preferable variant of integration of the considered systems - with the use of .NetFramework platform - is singled out. The advantages of using the Common Language Runtime for the implementation of the considered option of integrating R, MatLab and C # applications are noted.

Review of Design and Modeling of Regenerative Heat Exchangers

Heat regenerators are simple devices for heat transfer, but their proper design is rather difficult. Their design is based on differential equations that need to be solved. This is one of the reasons why these devices are not widely used. There are several methods for solving them that were developed. However, due to the time demands of calculation, these models did not spread too much. With the development of computer technology, the situation changed, and these methods are now relatively easy to apply, as the calculation does not take a lot of time. Another problem arises when selecting a suitable method for calculating the heat transfer coefficient and pressure drop. Their choice depends on the type of packed bed material, and not all available computational equations also provide adequate accuracy. This paper describes the so-called open Willmott methods and provides a basic overview of equations for calculating the regenerative heat exchanger with a fixed bed. Based on the mentioned computational equations, it is possible to create a tailor-made calculation procedure of regenerative heat exchangers. Since no software was found on the market to design regenerative heat exchangers, it had to be created. An example of software implementation is described at the end of the article. The impulse to create this article was also to broaden the awareness of regenerative heat exchangers, to provide designers with an overview of suitable calculation methods and, thus, to extend the interest and use of this type of heat exchanger.

The concept “computer environment” was studied, the analysis of literary sources was conducted, on the basis of which it was discovered that the issues of organization of teaching and research activities of students of engineering and pedagogical specialties of a computer profile by means of a computer environment require further research. The use of the knowledge representation model in the process of designing a computer environment is substantiated, the intellectual properties of the computer environment are considered, as a reaction to certain actions by the user. It is proved that when designing a computer environment, the network model of representation of knowledge in the form of a graph that reflects the meaning of a holistic image is most optimal for use. When using a network model, the course structure is represented by a set of modules that are divided into themes, and those, in turn, are assigned to tasks. Such an organization allows combining the entire study process into a single trajectory, which is adjusted depending on the student’s progress in mastering the material. The informational, programmatic and didactic components of the computer environment are substantiated, the basic requirements, which are presented to the computer environment of research work of students of engineering and pedagogical specialties of the computer profile as the object of design, are revealed.

РАСШИРЕННЫЙ ИНТЕРФЕЙС ЧЕЛОВЕК-РОБОТ С ДОПОЛНЕННОЙ РЕАЛЬНОСТЬЮ

The problem of managing robots and robots coalitions is one of the limiting factors that stand in the way of the introduction of robots and multi-robot systems. Overcoming this problem is to increase the level of autonomy of robots, as well as the improvement of remote control interfaces of robots. At the interfaces of human and robot interaction, mechanical controls, such as buttons, joysticks and touch screens, prevail at the moment. All of them require the operator to use hand and / or foot movements. One of the promising areas of interface development is the use of tracking the direction and nature of the operator’s gaze. The article proposes the use of an extended human-robot interface with augmented reality, based on the principles of tracking the gaze of a human operator when analyzing video data from the on-board video system of the robot. The design of augmented reality glasses, characterized by simplicity and affordability of performance, is proposed. This design uses a typical smartphone and case, which can be made using 3D printing. At the same time, there are no additional sources of illumination of the operator’s eyes, with the exception of the smartphone screen. An example of software implementation for such an interface is shown.

Synthesis method for alphabets of orthogonal signaling broadband communications

Subject of Research. A synthesis method for alphabets of orthogonal signal broadband messages is developed. An example of software implementation is given. The analysis of some particular and general properties of the synthesized mutually orthogonal signal broadband symbols and alphabets formed on their basis is carried out. Method. The method is based on the generation of pseudo-random N-dimensional vectors of their orthogonalization by the Gram-Schmidt method and subsequent transformation of the resulting orthonormal vectors into the corresponding frequency spectra according to predetermined rules. The spectra represent images of the desired orthonormal broadband signals in the frequency space. The result of the final synthesis is obtained during the inverse Fourier transform. Main Results. The paper presents an example of possible method program implementation in MATLAB language of computer mathematics system. It is shown that the obtained alphabets of orthogonal signal broadband messages have high correlation properties and can be applied in communication systems, in which stable recognition of signal messages at low signal-to-noise ratios is necessary. Synthesis of signal symbols in the frequency domain makes it possible to monitor effectively the signal spectrum, carry out the frequency transfer, create systems with frequency tuning, including pseudo-random modification, used to organize protected communication channels. Practical Relevance. High correlation properties of the received signal symbols provide the possibility of application in systems of multiple access with parallel use of the common frequency-time resource, realizing steganographic communication channels due to concealment of useful signal in the radio noise, and limited power of transmitting devices.
