In this paper, a compact matrix converter module is presented. The main goal of this module is to implement all the required circuitry to one compact module and ensure the easy expandability of the modules to construct matrix converters in various configurations. The types of the bidirectional switches are analyzed together with the advantages and disadvantages of different types. The physical sample of the matrix 3x1 module is presented and used power transistors are modeled to the MATLAB/Simulink environment. Finally, simulation of power losses is conducted and the efficiency together with the overall behavior of the modules is analyzed as well as the design of the input filter.

This paper deals with the theoretical study of metal dielectric structure with two-dimensional surface grating as an optical sensor for medical applications for sucrose solutions detection. In the proposed structure, a surface plasmon resonance (SPR) response of the plasmonic structure in a spectral range of 556.3 nm – 558.6 nm with a sensitivity from 112.5 nm/RIU to 235 nm/RIU was revealed.

Photonics, which is widely used for terrestrial telecommunication applications, represents a disruptive technology for the future Satellite Communication (SATCOM) scenarios, allowing to reduce the payload system complexity. Several payload subsystems can be implemented in the optical domain instead of in the electrical one. Among them, this paper investigates the microwave-photonic Radio Frequency (RF) signal mixing for frequency conversion. A configuration scheme of a photonic RF mixer based on a dual port Mach-Zehnder Modulator (MZM) and two photonic local oscillators, used as RF down-converter, is presented and its performance is evaluated in the specific case of a binary phase-shift keying (BPSK) signal down conversion.

In this paper, an algorithm for planning and distribution heterogeneous resources in a stochastic system with ordered sets of tasks is proposed. Processing resources and memory resources are considered. The algorithm is based on the GERT-network model with a new parameter – a random variable of resource. A system consisting of many parallel processes is described in the model. Each process includes multiple tasks. By finding the start and end times of a pair of tasks it is possible to determine whether one task can start when another has finished. If the probability is satisfied for a given value, then that pair of tasks can be performed by the same processing resource unit. The ordered set of multiple sequential tasks is the desired outcome. Each set comes with a probability of completing all the tasks in the set with only one processing resource unit. The fewer the number of sets, the more resources are saved. However, it is necessary to consider the probability of the set. Accepting a certain level of risk can save a corresponding number of resources. To support the computation process, an algorithm to find the distribution laws of any arc in the GERT-network has been introduced. It speeds up the computation and allows selected arc located on the loop. Assuming that the memory resources are released as soon as the task is complete, the total memory resources for the system are recalculated. An example of the analysis process, planning and distribution resources in network devices is given.

The paper examined parallel RLC resonance in Ti3C2Tx MXene (T-OH, Cl or F) deposited on polycaprolactone (PCL) electrospun membrane. Measurements were carried out using impedance spectroscopy method. Results of capacitance studies of the MXene-PCL nanocomposite are presented. At least 3 sharp minima are noticeable on the capacitance diagram. The depth of the minima indicate that in MXene-PCL nanocomposite parallel resonance occurs. For every minimum Arrhenius plot was prepared and for the first and third minimum activation energy was calculated ΔE=0.0048 eV (I minimum) ΔE=0.0375 eV (III minimum). Different activation energy for each minimum shows that at least three types of tunneling between nanoparticles occurs.

The development of materials science largely determines the development of the production of new materials for all areas of human life: medicine, building industry, transport, etc. Materials science in the education system, especially in electric engineering, ranks high. This is due to both the development of directions in instrument manufacture in electric engineering (microelectromechanical systems (MEMS), nanoelectromechanical system (NEMS), ultracapacitors, etc.), and invention and development of new materials (e.g, graphene). Creation of new methods and equipment for obtaining materials and testing their characteristics is also of great importance. The paper considers the development of methods and programs for teaching materials science in electric engineering using information technology (digital education). The role of online education in teaching materials science is considered. The work was carried out at the department of electronics of Ryazan State Radio Engineering University and Ryazan Region Housing and Communal Services Training Center.

The spherical robots are becoming very popular in the field for many scientists and researchers working with surveillance, military, or transportation systems. This paper deals with comparing of each driving mechanism of the spherical robot. The vast majority of spherical robots only have inertial sensors, which they use for movement, positioning, travel balancing, etc. Few spherical robots can interact with the environment. Those who can do this have sensors that can measure the properties of the environment or can influence the environment in some way. The article also deals with the possibility to use sensors like cameras, gas sensors, thermocouples, and LiDARs. Data from these sensors will be processed using artificial intelligence techniques to detect anomalies in the environments. Chosen sensors can expand a robot's sensing capabilities which are usually very narrow. The aim of the article is to design s special type of spherical robot. If we join all these components together we can create a reconnaissance spherical robot for rescue services special designated for tunnels or closed spaces.The prototype is a financially inexpensive robot, which is also suitable for the teaching process, as an element that collects data from the environment (sensors, video, etc.), which will be used for working with AI tools.

The paper presents the results of testing the polarization currents and DC conductivity of electrical pressboard produced by Weidman company, containing water nanoparticles with content of 4 wt. % and impregnated with mineral oil of natural origin NYNAS NYTRO BIO 300X. The time dependence of polarization currents and DC conductivity was determined for measurement temperatures in the range of 20 - 70°C. Arrhenius plot was prepared for 6 temperatures from the whole range of measurement temperatures. Linear approximations of the experimental results were made on the Arrhenius plot. The activation energy of the DC conductivity and the values of the coefficient of determination R2 were determined. The values of the coefficient of determination close to unity testify to the high accuracy of the measurements and the stability of the temperature. It was found that the value of the activation energy of the conductivity for the pressboard impregnated with mineral oil of natural origin NYNAS NYTRO BIO 300X is ΔE = 1.117 eV.
