Modern technical means are certainly a necessary element of the checkpoint, and the checkpoint as part of the security system will clearly perform many functions.

Analysis of training success within the framework of the problems of pedagogical psychology

Today, for the majority of students at universities, study takes place in a distance format. The reason for the transition to a new format of education was the outbreak of coronavirus infection in 2020. The distance learning format at the initial stage was associated with a lot of difficulties. This is an incomplete provision of educational institutions with modern technical means, the dominance of stereotypes of the traditional format of education, as well as a complete or partial lack of experience in working online. However, these problems were gradually resolved and the learning process improved. The purpose of this article is an at- tempt to conduct a psychological analysis of empirical data on the success of student learning in the online format, namely: to consider the dynamics of changes in the indicators of learning success, as well as to compare the effectiveness of the educational process in distance and traditional formats. The value of the article lies in the collected information, on the basis of which it is possible to trace the change in the situation of student success, the positive and negative aspects of each of the learning formats, taking into account the data considered, build a more effective blended learning format. These articles were obtained on the basis of an analysis of literary sources and the results of a questionnaire sur- vey of bachelors, undergraduates and professors of technical specialties. The results of the study showed the current situation of education in a higher educational institution - Satbayev University - after a year of distance learning. Key words: pedagogical psychology, learning success, traditional learning, distance learning, tech- nical student, tertiary education, potential, COVID-19.

MODELING OF A SYSTEM FOR AUTOMATIC REGULATION OF THE TENSION MODE IN THE ROUGHING GROUP OF STANDS OF A CONTINUOUS SECTION MIL

The subject of the research is automatic control system modeling features for tensioning of stands roughing group, which takes into account changes in the rolling speed at exit of the previous stand and entrance to the next stand. Control systems for high-speed rolling on section mills are the most critical systems, since the trouble-free operation of rolling mill largely depends on their work. Rolling speed control is understood to mean tension regulation in the roughing group of stands and stabilization of the rolling loop in the finishing groups. The influence of such technological factors as uneven heating of blanks, change in the crimping mode in stands, etc. leads to the appearance of tension or back-up forces, deviation of rolled loop from the specified values. Tension rolling, in contrast to loop rolling, is a stable rolling mode. However, (at significant values of tension in the rolled products) such a rolling mode leads to different thicknesses of the finished product. The loop rolling mode is an unstable mode and is impossible without automatic control systems. Both in the tension rolling mode and in the free rolling mode with a loop, it is necessary to study automatic control systems in order to determine the possibilities of compensating for disturbing influences and obtaining rolled products of the given accuracy. Therefore, the main task of the automatic control system is to maintain the rolling mode with the lowest possible tension. To achieve this goal, direct control of the tension of the rolled strip with modern technical means is rather difficult, and the operation of tension control systems is based on indirect methods of measuring it, and the study of the system efficiency is reduced to modeling the process itself. The developed model consists of three stands and two inter-stand spaces, since it takes into account changes in rolling speed at the exit of previous stand and the entrance to the next stand. It is due to this that adequate simulation results are obtained that are close to the real rolling process.
 Keywords: automation, rolls, stand, inter-stand spacing, modeling, loop tension, rolling mill, roughing group.

Problems formed by everyday information and communication sphere of holding

An unheard-of triumph of mankind in the last century was that in the process of the development of science and technology, information and communication technologies (ICT) exploded most vulnerablely, and we, at a new ideological level, comprehended the importance of information and professional awareness of citizens as a resource for the modernization and development of countries. Under the influence of ICT in the twentieth century, communication began to develop rapidly in science, education, industry, economics, medical and military affairs, etc. The arrays and quality of meaningful information that have been accumulated over the centuries, and in different countries it was done in different ways, in the twentieth century for the first time began to intensively integrate into the system of world knowledge, laying the foundation for the formation of a global system of information exchange and human communication. The coordinates of the capabilities of modern technical means that form information and communication networks and systems, over the past thirty years have significantly expanded the world, radically changed the concept of information and communication activities, and its digitalization in general, increasing the requirements for it, internationalized and unified standards, translating the development of society to a new level. The requirements for education and professional training of people who work in the information and communication sphere have also radically changed. We see all this in the examples of the integration of the latest ICTs into the totality of all information and communication, political and legal, scientific, educational and financial and economic processes, which, in turn, are rapidly changing human society in the harmonious unity of all their elements, integrating the potential of humanity and increasing the power of influence on our consciousness of the global information and communication space (ICP). The world community poses before each state extremely difficult issues of conducting an appropriate information and communication policy in order to adapt its citizens to living conditions in a new information and communication reality, requiring legislatively to form a new vision of human rights and responsibilities to meet information and communication needs in society and, thus Thus, to prepare their citizens for life in the new realities of the world, the life of which is based on the use of information as the main resource for development. Key words: information, informatization, communication, information and communication technologies, information and communication security, information and communication activities, information and communication space, information and communication legislation.

Preparing Future Officers for Performing Assigned Tasks through Special Physical Training

The use of the newest pedagogical technologies (techniques) with the accentuated influence of the modern technical means of training during practical classes with the SPT and other forms of physical training with the cadets of the National Academy of National Guard of Ukraine during their professional development ensures that they acquire the necessary level of readiness to perform assigned tasks and is the priority of the scientific research. The article aims to formulate a model for forming future officers' readiness to perform assigned tasks using special physical training in higher military educational institutions and to analyze the results of the pedagogical experiment on its implementation. While conducting the pedagogical experiment, the modern technical means of training and functional complexes were used, which increases the level of special physical readiness among the representatives of the experimental group. Also, pedagogical conditions for forming future officers’ readiness to perform assigned tasks using special physical training at the Command faculty of the National Academy of the National Guard of Ukraine were experimentally verified. To improve the “shock” technique of HHC (the technique of applying physical activity measures) and the explosive force, we used the hardware-software system of the martial arts technique “Katsumoto” impact registration (HSS “Katsumoto”), video monitoring of technical handicap operations, Human Reactions Complex (AECS – LAB). Experimental work was implemented in two groups: the control group (CG, n=62) and the experimental group (EG, n=61). It is experimentally confirmed that the high qualification level of special physical readiness ensures the high-quality performance of assigned tasks.

Istoricheskoe ponimanie tekhnogennoj civilizacii

The intensive informatization of modern culture is due to certain reasons. It is a means of balancing those factors that pose a threat to human existence. With the help of widely implemented information technologies, society is trying to prevent global disasters that are the result of uncontrolled human activity. But even the intensive informatization of culture does not protect it from the destructive actions of modern man, “armed” with modern technical means and the latest technologies.

THEORY AND PRACTICE OF AGRICULTURAL MATERIALS MOVEMENT IN LIQUID AND AIR ENVIRONMENTS UNDER CONDITIONS OF GRAVITATIONAL FIELD

Existing technologies and modern technical means do not always provide the required quality of technological processes of growing crops. The growing demands in a competitive market environment necessitate the constant improvement of existing and the creation of new high-performance machines and machine units to ensure the quality of technological processes in precision farming systems. The article presents improved theoretical principles of practical applied direction of agricultural materials MOVEMENT in air and liquid environments under the action of gravitational field. As a result of research using a fundamental analytical and mathematical apparatus, an algorithmic model has been developed that describes the movement of: seeds or mineral fertilizers on the way from seed drills to furrows, which are formed in the soil after the passage of seed drill openers; grain that moves from top to bottom in the cleaning systems of combine harvesters or during unloading from the hopper, etc. Such processes and phenomena occur during the production operation of seeders and planters, machines for post-harvest processing of grain, harvesting of roots, fruits, berries, etc. Particular attention is paid to the fall of raindrops or drops created by irrigation systems. The influence of the impact of drops on the field surface is analyzed, which provides the development of practical recommendations for the prevention of soil erosion, which is especially relevant in fields with difficult terrain. Some technical systems of creating "artificial rain" are considered, their technological schemes are substantiated and constructive and technological parameters are optimized. The application of the algorithm of mathematical analysis and calculation of technological processes and technical systems provides the necessary conditions for seed germination, growth and development of crops in both plain fields and on sloping lands. In addition, the proposed innovative methods of theoretical analysis and calculation of processes and phenomena characteristic of agro-industrial production can be effectively and used in the educational process during the preparation of agricultural engineers for project professional activities.

Justification of traffic signaling modes at intersections considering the priority of public transport

With the growth of the road transport fleet and increase of urban agglomerations, the availability of private transport on the streets of cities with a population over 500 thousand inhabitants is quite noticeable. The previously developed general plans of such settlements, in modern realities, are impossible to implement both from a financial point of view and in terms of the urban space organization. Given the impossibility of meeting the needs of private car users, public transport comes first in the priorities of urban mobility. Problematic areas of the road network in many western Ukrainian cities are those that are densely populated. In such cases, it is not always possible to redesign elements of street sections or intersections, so the traffic management improvement is limited to organizational measures. Among them, the most popular and least expensive are the change the modes of light control at intersections. Considering modern opportunities, technical means and scientific achievements, the capacity of signalized intersections is high. The same applies to the principles of giving priority to public transport over time (at signalized intersections). At present, a significant number of methods and algorithms for detecting and heading the movement of public transport at traffic lights have been developed, however, the criteria for the application of each of them are not fully understood. As a result of the conducted research, the change of queues in front of stop-lines at intersections depending on types of signalization is defined. The results showed that the existing type of control creates significant traffic delays on secondary streets. As a result, it is proposed to use adaptive control, which provides for the adjustment of the traffic light cycle in the presence of tram traffic. Using traffic simulation tools, it became possible to choose different modes of traffic lights control at intersections, which can provide public transport priority, while minimizing the negative impact on the adjacent elements of the road network.

EVALUATION CRITERIA OF THE OFFICE BUILDINGS INTELLECTUALITY

The article defines the main criteria of office buildings intelligence, describes the stages of intelligent buildings formation, analyzes the profitability of the introduction of modern technical means (engineering systems) and architectural planning techniques in office buildings. At different stages of civilization, the concept of "technology" defines the path leading to future progress, and the rate of technology change is directly proportional to the rate of progress. Nowadays, artificial intelligence is extremely important for the functioning of modern office buildings, including the impact on the environment, resource conservation, safety, comfort and life support. According to research based on the works of scientists such as Derek Clements-Croome, Mervi Himannen, Akin Adejimi and others, and based on the analysis of intellectual buildings of the world from the 50s of the twentieth century to the present, 4 stages of intelligent buildings formation were identified. At the first stage (1950-1980) of the formation, separate controllers were introduced. At the second stage (1980-1995), the introduction of the "artificial intelligence" - Building Management System (BMS) - was developed and used. At the third stage (from 1995 to 2010) an intelligent building management system (IBMS) was introduced, which can independently identify threats, look for ways to achieve results and make decisions. Starting from 2010, we can highlight the fourth stage of development of the intelligent buildings, in which, in addition to the availability of the intelligent management system (IBMS), it became necessary to use approaches of sustainable architecture. The research results indicate that the office building should be classified as an "intelligent building" if it meets the following criteria: 1. Has artificial intelligence (IBMS), which autonomously manages the building; 2. Has at least 15 thousand information points, in other words, sensors and controllers, through which information is received from controlled engineering systems about the state of equipment and the environment, the state of building structures, etc.; 3. Complies with the principles of sustainable architecture, when planning and architectural techniques can minimize the negative impact of buildings on the environment through energy efficiency. The article proves that the office buildings intelligence is determined by the availability of both technological means and the optimal architectural concept, which minimize the negative impact of buildings on the environment; improve energy efficiency and conditions of the building exploitation. Therefore, further research of intelligent buildings from the point of architectural view is necessary, because a modern office building must be designed with the ability to adapt to rapid changes in technology and human needs.

Research and Application on the Language and Literature Based on Network Information Technology

With the rapid development of computer technology, network information technology (hereinafter referred to as NIT) has become an indispensable basic tool in people’s work, which has been applied to all walks of life in our country, including literature education. Language and literature (hereinafter referred to as LAL) are the extension of excellent traditional culture, which is the legacy of the history of all nationalities. Therefore, the study of LAL should not be stagnant, which needs to adapt to the modern technical means. Through the NIT, we can promote the progress of Chinese LAL, which will also have a significant impact on the audience. In the face of the impact of the network, the network culture has been greatly applied, which has a great impact on our traditional literature. With the popularity of Internet catchwords, some people tend to forget their words, which has gradually ignored the art and charm of traditional culture. Therefore, colleges and universities must use NIT to assist LAL research, which will strengthen the understanding of literary works. First of all, this paper analyzes the important role of NIT in LAL teaching. Then, this paper puts forward some problems. Finally, some suggestions are put forward.

 The article is focused on the problem of training future tourism specialists using informational and communication technologies. The educational process of preparation requires changing the educational and methodological support in order to give the students the opportunities to master modern professional tools, technologies, methods of creating high quality tourist products. To solve this problem, the authors propose a model for the development of high quality training of tourism professionals through the use of computer 3D-tours. The development of this model took into account the theoretical and methodological basis regarding the professional training of future specialists in the field of tourism, the results of the analysis of educational programs, curricula for training students of the speciality “Tourism” and the data of the pilot experiment. It consists of the following main blocks. The conceptual-oriented block includes concepts, approaches, principles of participation, information and communication technologies. The content-technological block includes the content of the educational project of developing 3D-tours, levels of professional knowledge and skills, as well as types of familiriazation with ICT tools. The educational content of the model takes into account the practical mastery of the student’s professional skills in the development of various 3D-tours. During this process, the ICT tools are introduced gradually in a certain order. The organization-activity block of the model includes forms of organizing the study and technologies for studying. This model entails the involvement of classroom-based and remote, individual, and group forms of organization of the educational process, organization of project development for a detailed analysis of educational topics. The assessment-resultative block includes criteria, metrics and levels. During the development of the model, the results of the activity of thesubjects of the educational process were analyzed in accordance with two groups of criteria: the criterion of formation of professional theoretical knowledge, practical skills of 3D-tour development and the criterion of the level of using modern software and technical means in creative educational development. The developed model allows for increasing the quality of training of future tourism specialists. During the practical application of the proposed model, virtual 3D-tours were developed.

МАТЕМАТИЧЕСКАЯ МОДЕЛЬ ДВИЖЕНИЯ ЧАСТИЦЫ ЛЕСОСЕМЕННОГО МАТЕРИАЛА В РАБОЧЕМ КАНАЛЕ СЕПАРАТОРА

Preparation of high-quality seed material for the needs of forest seed stations aimed at the reproduction of forests with seeds with improved hereditary properties requires the use of special seed cleaning machines. The use of such seeds with improved hereditary properties will provide an increase in the productivity, quality and sustainability of plantations. Seed material of different species has features of surface and shape, taking into account these differences, various machines and installations have been developed and widely used. The need to use special machines for magnetic cleaning is caused by the impossibility of high-quality separation of seed material. Analysis of modern technical means of seed preparation showed that the idea of combining air and magnetic cleaning deserves special attention. During pneumomagnetic separation, various forces act on a particle of the seed mixture, the magnitude and direction of which change depending on the design parameters of the working body of the inductor and the position of the particle of the seed mixture in the magnetic field of the inductor. It is possible to study the movement of a particle in the operating channel, as well as to construct a mathematical model, by making some assumptions, the result of which makes it possible to study in theory the influence of design and technological parameters on the separation process of forest seed, as well as to determine the regularities of the process of pneumomagnetic separation. Based on the results of the analysis of the movement trajectories of the seed mixture, curves of the movement of particles are plotted at various values of the magnetic force in the working channel, and graph is presented that illustrates the possibility of carrying out the process of pneumomagnetic separation depending on the ratio of the air flow rate and magnetic force acting on the particle. It has been determined that the process of pneumomagnetic seed cleaning can be effectively carried out at an air flow rate of 3.5 ÷ 5.2 m/s, and a magnetic force of 3.4 × 10-6 ÷ 8 × 10-6N. It is necessary to create a magnetic field induction in the range of 0.115 ÷ 0.177 T in order the magnetic force to have such a value in the working channel.

REGARDING THE USE OF MODERN TECHNICAL MEANS OF PROTECTION AGAINST FLOOD OF TERRITORIES AND FACILITIES FOR DIFFERENT PURPOSES

The danger to society caused by the consequences of natural disasters tends to increase despite the general technical progress and the application of measures to prevent them and combat them. Every year the number of victims, in particular, from floods increases by an average of 6%. Flooding in certain areas can occur due to floods and inundations. Floods are natural processes that occur in the biosphere and affect the planet for millennia. Flood is a significant flooding of the area due to rising water levels in rivers, lakes, reservoirs, caused by downpours, spring snowmelt, wind surges, destruction of dams, dams and more. Floods cause great material damage and casualties. The water level in reservoirs depends on many different factors. All over the world, experts conduct long-term observations, tracking all seasonal changes, and collect data for forecasting. Floods and their causes are well studied. The main causes of these disasters are: - prolonged rains; - melting snow; - raising the bottom; - strong winds and storms; - groundwater; Thus, the issue of using modern technical means of protection against flooding of territories and objects of various purposes is relevant. A number of publications consider current trends in effective flood risk management planning in the European Union and describe the catastrophic consequences of floods and ways to combat them, and so on. At the same time, these studies do not contain data on testing and implementation in Ukraine of modern technical means to combat floods in the EU. To address these issues, the Institute of Public Administration and Research on Civil Defense commissioned by the State Service of Ukraine for Emergencies has developed a method of testing water-absorbing devices designed for: - flood protection; - changes in the direction of water flow during floods, torrential rains, melting snow, etc. - removal of water from flooded areas (basements, garages, etc.); - elimination of environmental accidents (spills of oil, diesel fuel and other chemicals). Developed by the Institute of Public Administration and Research on Civil Protection, the method of testing water-absorbing means will allow in the future to test and assess the suitability of such technical means for use by fire and rescue units when performing tasks to remove water from flooded areas and create barriers to water. time of protection against floods, changes in the direction of water flow during floods, torrential rains, melting snow, etc.
