The article presents the criteria for evaluating the integration of researchers in the scientific community, based on an analysis of its citations. It is known, that one of the major components of interscientific communication (communication in the scientific community) is a citation of scientific publications (monographs, articles, etc.). According to the sociological approach, a scientist is a part of society, ie, scientific community; under scientific community we understand scientific mega environment (opposed to research groups of institutions and their structural units). Integration of a researcher to the community has many aspects: on the one hand, it is - the importance of his work to the scientific community, on the other hand, it is - the use of a scientist social mega environment for building for their personal and professional development to improve their research and improve the quality of its results (in the context of the article we will consider the second aspect). Methodological bases of the research: systematic, competence, sociological, and mega-system qualimetric approaches. Methods: modeling, methods of quality control, methods of set theory, relations and graphs. Evaluation (diagnostics) involvement of scientists in the scientific community - is more complicated metrology task than the evaluation of the significance of the results of its research activities. For the authors it is clear that a mature scientist (with a high level of research competence) should intensively use the potential of the social and the cultural science international environment (community) for their personal and professional development, to improve the efficiency of this research activities and the quality of this results. The proposed indicators can be considered as group indicator variables reflecting the level of the behavioral component of the research competence (scientist). Using social media for researcher’s potential – it is necessary, but not sufficient condition for productive research, producing goodquality scientific results. In this situation, negative prognosis is more significant: poor use of social media for researcher’s potential – is a "guarantee" for low productivity of this research activities and the low quality of this results. Only the combination of the highest levels of readiness for research (research competence) with high levels of other competences (as a whole - the social and professional competence, implying the presence of the professional skills of selforganization) can be the factors of successful research

Conditions in which the work of acoustic magnetic device proceeds are complicated because of the number of interconnections. Solving problems under such conditions analytically is difficult because of many variables and complexity of some dependencies. The article describes the conditions in which the work of acoustic magnetic device, designed for nonchemical treatment of hydroponic solution, takes place. The criteria, establishing the initial state of the chains, containing mutual inductance, are analyzed. The work establishes the criteria relating the physical parameters of the environment with the output parameters of the device. The similarity of conditions of heat transfer on the surface of the device is provided, and the relation of the scale of temperature and power lost when heating the ferrite and winding machine is determined. The criterion of the heat transfer process is defined. The criterion, determining the relation of the environment temperature to the thermal mode of the acoustic magnetic device, is defined. The criterion of the conditions at the boundaries of the system and cavitating liquid is determined. It is found, that the cavitation area appears in the technological volume of liquid at the work of acoustic magnetic device. The criterial equation for geometric parameters of different types and constructions of the acoustic magnetic device is defined. In accordance with the task based on the third theorem of similarity, the group of criteria that provides the similarity of the model to the proposed original by all existing indicators, is selected

The goal of the study is to research a noise-immunity of pseudo-noise sequence acquisition method for multicarrier communication systems MC-CDMA, using a segment of the pseudo-noise sequence. The goal was achieved by running a simulation developed in MATLAB. By analyzing the results, we can show that the developed mathematical model produces the lower bound for pseudo-noise sequence acquisition probability. The resulting analytical estimations might be used during the design phrase for pseudo-noise sequence acquisition systems for MC-CDMA based military communication networks

The goal of the study is to analyze the existing quantum distribution systems, their probable applications, as well as the issues with their practical implementation

Grain is of strategic importance and is the basis for food security. The gross national product share of grain and its products is about 10-15%. It always stands out from other types of raw materials, as it is used to produce the most popular daily foods. According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of adaptation and the possibility of using the model and the method of binary matrices to solve the problem of the choice for cropping technology

The goal of the study is to research time characteristics of pseudo-noise sequence acquisition method for multicarrier communication systems of MC-DSCDMA, that allows low hardware requirements and able to operate in low quality channels. The way of achieving this lies in using a mathematical model of algorithm. The achieved results show suitability of MC-DS-CDMA-signals optimization for pseudo-noise sequence acquisition efficiency increase. The achieved results can be applied in MC-DS-CDMA communication systems development

Augmented reality offers unique ways to display visual information, in particular the visualization of threedimensional objects. With AR object can be visualized directly in the context of its operation. As an example can be a piece of furniture rendered in the interior, plants in the garden, the architectural object in the landscape. Modern consumer devices such as smartphones and tablet computers, as well as the algorithmic base lead to the possibility of augmented reality mass usage. The concept of augmented reality offers a better user interface for visualization through a combination of methods of controls and visualization. The camera angle can be controlled by user’s head or device movements, which is intuitive and efficient. Method of visualization of three-dimensional object by combining its image with the surrounding environment allows better perceiving the object, its dimensions, and material properties. In contrast to the traditional visualization approaches, AR does not require modeling of the environment. Objects visualization by means of AR can be applied to customer decision support while buying products. The user is provided with the ability to visualize an object in interior or outdoors, where he plans to place it, and interactively examine the object from any angle. This article attempts to systemize possible options for interaction with potential buyers through applications with augmented reality technology

Tracking is a vast field of research associated with navigation, robotics, and virtual environments (virtual reality). Tracking for augmented reality requires higher level of precision, increased range of action, as well as work with a wider variety of input data. It is important that augmented reality technology requires tracking in real time, which also complicates the task. Correct visualization of objects in three-dimensional space requires six degrees of freedom tracking: three position values (x, y, z) and three angles (rotation around the respective axes) to determine the orientation. To solve this problem, different approaches and sensor types are being used. In this article, we present a brief history of the development of tracking technology and analyze the current approaches to implement the process of tracking on mass mobile devices such as smartphones and tablet computers. We also describe some issues in implementing optical marker based tracking for visualization of large scale models

The purpose of this research is the development of models and methods of multiparameter diagnostic effectiveness of educational environments. We know, that a criterion-diagnostic system for monitoring the effectiveness of higher education institutions - educational Macromedia is being designed, which is not the monitoring of the effectiveness of educational microenvironments and meso-environment - departments and faculties. The issue of the research - to increase the productivity (efficiency) of functioning of educational environments. The problem of research is the question of how to diagnose the effectiveness of educational environments objectively and comprehensively. The urgency of this problem is due to: the need to ensure the effective functioning of educational institutions, their sustainable innovative development; increasing demand for general and vocational education, as well as its transition to a multi-level system. Methodological basis of the research: a competence-based approach (considered an important target value of the educational process formation of the competences and personal and professional qualities of students, integrating knowledge, skills and readiness for their effective use in solving of life, professional and educational problems), metasystem approach (considering the educational environment as a metasystem, including relatively independent subsystems - educational environment of lower level of the hierarchy), qualimetric approach (considering the effectiveness of the educational environment as an integrative figure, which is diagnosed on the basis of estimating a set of criteria), synergetic approach (considering the educational environment as a self-organizing system, and the efficiency of its functioning - as an indicator of the success of the use of resources for further development). Synergetic approach is relatively new in the evaluation of the effectiveness of the educational process and the educational environment as a whole
