This paper presents a specific application of Cuk's DC/DC converter for a wide range of input and output voltage changes, which was used as a basic converter for the realization of a digital implementation of MPPT algorithm. The control part of the converter is realized on the basis of the microcontroller PIC18F4520, company Microchip. In the paper the basic properties of the realized MPPT converter are given, as well as the key results of experimental tests obtained for different values of input power.

The paper presents dimensioning and verification of the design of a powerful 22 kW electromagnet powered from a 220 V DC source. The application of the designed electromagnet refers to systems for electromagnetic separation of medium and large steel parts that may be found in the coal that is transported on the conveyor belts for the delivery of coal to thermal power plants. The application of the electromagnetic separator is directly related to the system for detecting the presence of metal steel parts (metal detector). In the case of inefficient operation of the system for separation of steel parts from coal, severe accidents can occur in the system for grinding and crushing coal at thermal power plants. The design of the electromagnet presented in this paper was verified in the software package FEMM 4.2. The model is defined as a 2D planar magnetostatic model. At the end of the paper, the final simulation results of this project are presented.

The central topic of this paper is the performance comparison and potential issues of the container-based virtualization, with Docker and Podman as typical representatives. The measurements validity is managed with the use of the same testing environment, the identical hardware and software components. The testing procedure is conducted by the means of the Filebench, on CentOS Linux 7. The goal is to evaluate an impact of one and more container-based virtual machines on the file system performances. The obtained results are thoroughly explained and further presented in graphical form.

For researchers and the academic community, it is of great interest to regulate traffic at intersections with several lanes. In certain periods during the day, the need to extend the interval of passage in certain directions at the intersection increases. In order to determine how to extend the interval, it is necessary to apply advanced technologies of the Internet of Intelligent Devices (IoT). Built-in sensors, in addition to the basic purpose of motion detection, also have the possibility of mutual communication as with other devices. The collection and immediate analysis of data in the database of the Traffic Dispatch Center (SDC) provides the service with information to improve the throughput of intersections in the direction that is most loaded. The main goal of the paper is to present an innovative model of traffic regulation of timely and immediate extension of the time interval for the necessary directions at the intersection.

Due to the amazing development of the internet, today if you don't transfer your business to the web it's like you don't even exist. That is why we are witnessing the growing development of web applications that allow users to complete all their tasks with only one click. Cinema is a partly complex system because many processes take place within it, so the focus of this paper is the automation of the process of booking and selling tickets for movie screenings in cinemas. This paper presents the development of a web-based information system that will enable its users to quickly and easily book tickets for movie screenings in the selected cinema.

The generation of airborne particles in the friction nodes is an important aspect of modern tribological research. The paper presents the results of experimental studies on the intensity of airborne particles precipitation during friction of dry stellite 6 and $boldsymbol{text{Fe}_{3}mathrm{A}1}$ intermetal after 1.0037 (S235JR) steel. These materials are used on valve seats of internal combustion engines. Abrasion tests were performed on a T-11 pin-on-disc tester. The test conditions were similar to those prevailing during the operation of the valves in the head of the internal combustion engine, disregarding the influence of temperature. The TSI OPS 3330 optical spectrometer was used to measure the intensity of generation of wear particles, which enables the measurement of particles in the range from 0.3 to 10 $boldsymbol{mu mathrm{m}.}$ The obtained results indicate that the $boldsymbol{text{Fe}_{3}text{A1}}$ intermetal in contact with the 1.0037 S235JR steel generates 15% less airborne wear particles in the tested range.

We study quantum features of electromagnetic radiation propagating in a waveguide built of an infinite array of super-conducting qubits (SCQ) placed within a resonator comprised of two massive superconductors. Such engineered media, so-called superconducting quantum metamaterials (SCQMM), have a great potential for quantum information processing and communications and devise a comprehensive study of the nature of the “light”-matter interaction. We predict the emergence of novel in-terference effects with possible practical applications. For exam-ple, photons may exhibit a nontrivial dispersion relation such as band edges and band gaps. In this way, QMMs may be viewed as photonic crystals. This, in turn, enriches their potential for practi-cal applications and provides novel means for devising compre-hensive studies of both practical and fundamental aspects of the interaction of artificial atoms and the EM field.

In accordance with the current situation around the virus pandemic, the basic preconditions are being created for the application of electronic business technologies in companies whose activity is the transport of passengers in traffic. In this paper, an analysis of e-business technologies that can be applied in traffic is performed with an emphasis on increasing the quality of service, customer satisfaction as well as opportunities to improve financial profits in companies and increase the competitive advantage of transport services. The application of e-business technologies in companies also requires the reengineering of business activities that are applied, through the upgrade of existing computer systems with the application of innovative models and services based on mobile technologies.
