Representing magnetic saturation in the AC synchronous machine models increases the accuracy of computer studies. Common approaches include considering the saturation along the d-axis only, along the qd axes separately, and along the main flux path. The last approach generally has a better consistency with the experimental results. This paper proposes a new saturable phase-domain (PD) synchronous machine model for the EMTP-type solution utilizing the single-saturation factor to represent the main flux saturation. The proposed PD model incorporates a piecewise-linear function for a numerically-efficient representation of the nonlinear saturation characteristic. Computer studies carried out in PSCAD demonstrate the effectiveness and high accuracy of the new proposed PD model with respect to other existing state-of-the-art saturable synchronous machine models.

The article considers the problem of the influence of coal generation on the ecology of Krasnoyarsk. Coal-fired generation is one of the main sources of pollution of the city. The level of ecology reflects the quality and standard of living of the population. In the developed countries of the world, ecology is given a significant priority in solving many economic problems. The specifics of the fuel and energy balance are such that more than 90% of all energy consumption is carried out through the use of coal. When burning coal, a lot of harmful substances are released, which have a great impact on the ecology of the city. This paper presents possible solutions: 1) Raising the pipe of the combined heat and power plant (CHP); 2) Gasification of the Krasnoyarsk CHP. The issue of conducting gas in Krasnoyarsk is considered. The analysis of the above-mentioned solutions is also carried out. The calculation of the costs for lifting the pipe, as well as for gasification, was carried out. Comparative tables of "emissions from coal and gas" and "costs and efficiency between pipe lifting and gasification" are given. Based on the results of the analysis, it can be concluded that these solutions can be used.

This article considers the problem of the impact of the pandemic on medical personnel in the Russian Federation. During the pandemic, one of the most acute problems is the shortage of medical personnel. The study of the issue of shortage of medical personnel is relevant both for the whole world and for Russia. The authorities of several Russian regions at once, against the backdrop of an increase in the incidence of coronavirus, announced an acute shortage of doctors and mid-level health workers. In Russia, first of all, there was a shortage of primary health care doctors - general practitioners, general practitioners, and pediatricians. Staffing problems were discussed even before the pandemic, but during the pandemic, the workload on the medical staff increased and existing specialists began to leave. This paper presents possible solutions. Such as increasing wages and attracting students to increase staff. The purpose of the study is to analyze the reasons for the lack of personnel, identify existing problems, and formulate recommendations for their elimination.

The quality of images is influenced by the distortion, brightness and contrast of the acquired images. Understanding the image’s histogram is probably the most important element when working with images. The histogram shows whether the exposure of the image is correct, whether light is hard or soft and what changes could be made to obtain a better image. Three algorithms have been studied for enhancing digital images’ contrast. All algorithms are applicable to color images as well. Results show that selecting appropriate numerical methods for image processing is a key factor in achieving the goals.

The use of open data in education at all levels of education brings enormous advantages in easier acquisition and sharing of knowledge. Data available to everyone is of great importance in all spheres of society, and in the era of Industry 4.0, it immeasurably helps in making more informed decisions. In education, open educational resources can be used to connect people around the world and solve many real-world problems through innovation. This paper presents the basic concepts of open data, and the emphasis is on the importance of open data in education. Good practice examples are presented, as well as the challenges that open data entails. Also, the current situation in Serbia in terms of educational open data was analyzed, as well as suggestions for improvement.

This paper presents design, production, testing and biomedical application of an interdigital capacitor made exclusively from edible materials (food). The purpose of this work is to demonstrate suitability of the sensor made from edible materials to detect pathological condition in the oral cavity. Interdigital capacitors were made on edible substrates such as biscuits, edible wax, and buckwheat tiles, while aluminum foil was used to make the conductive segments. The tests were performed at room temperature with the HIOKI IM3590 impedance analyzer device.

Defining the required performance for any two axis gimbal system is an important and complex task. In order to define the system requirements, it is first necessary to define the system application. The basic structure of the system is presented and a performance analysis required for the two axis gimbal system in application in multisensory imaging system devices is given. The methods of verification of specified performances were discussed and a practical guide was given for the selection of the basic components of the system based on the defined required performances.

When students enroll at universities, various datasets can be available to managers and teachers. Clustering techniques can be applied in order to divide the instances within those datasets into natural groups. In this paper, one clustering-based approach combined with attribute selection methods for identifying specific input dataset variables meaningful for the disjunction of distinct students' profiles has been proposed. Also, an analysis of the descriptive students' model obtained by the proposed methodology is performed.

This paper describes the functionality and the results of the Threat Surveillance mini-project on computer vision. Its main objective is to create and offer the possibility of monitoring and detecting cold and fire weapons, while maintaining public safety. Created not only for military purposes but also for civilian ones, the project proposes a simple graphical user interface (GUI) which is aimed at maximum user convenience. The core of the functionality is however based on advanced commercial software belonging to artificial intelligence (AI), called Yolo - V7. It is an algorithm of real-time object detection. The GUI allows personalizing the application execution by choosing the targeted weapon category along with loading a photograph or video which contains the category to be detected/recognized. The weapon detection part provides possible bounding boxes where the desired weapons might be situated in the chosen media and classifies them according to the object classes previously created by training.
