    Image recognition is an information process implemented by some information converter (intelligent information channel, recognition system) having input and output. The input of the system is fed with information about the characteristics of the objects being presented. The output of the system displays information about which classes (generalized images) the recognized objects are assigned to. When creating and operating an automated system for pattern recognition, a number of problems are solved, while for different authors the formulations of these tasks, and the set itself, do not coincide, since it depends to a certain extent on the specific mathematical model on which this or that recognition system is based. This is the task of formalizing the domain, forming a training sample, learning the recognition system, reducing the dimensionality of space

    Dielectric barrier discharge KrCl - and XeCl-excilamps radiation power control by pressure jump method

    The energy dissipation processes in dielectric barrier discharge KrCl- and XeCl-excilamps at various voltage, frequencies and pulse duration are revealed by a pressure jump method. It is offered and tested a way of radiation power calculation in conditions of non-uniform filling of device bulb by discharge plasma. The previous data (Pikulev A.A., Sosnin E.A., 2010-2013) are confirmed. The regularity was formulated: conditions of maximal ultraviolet radiation power corresponds to conditions of maximal heat release in plasma.

    Microconstituents of the Modified Surface Layer of Austenitic Steel With Nanofibres of Aluminium Oxyhydroxide

    Get PDF
    In the paper the authors provide the results of experimental study of the effect caused by introduction of nanostructured fibres of aluminium oxyhydroxide into the surface layer of austenitic steel upon its microconstituents. The authors show that, due to introduction of given fibres dendrite size is reduced and equilibrium structure is formed

    The paper provides the results of experimental research into the influence of aluminum oxy-hydroxide nano-structured powders on the microstructure of modified layers. It has been demonstrated aluminum oxy-hydroxide nano-structured powders AlO(OH) applied as modifiers bring about the decrease in dendrite dimensions, support equilibrium microstructure formation, and cause the growth of microhardness

    A planar source of atmospheric-pressure plasma jet

    Get PDF
    In a single-barrier discharge with voltage sharpening and low gas consumption (up to 1 L/min), plane atmospheric pressure plasma jets with a width of up to 3 cm and length of up to 4 cm in air are formed in the slit geometry of the discharge zone. The energy, temperature, and spectral characteristics of the obtained jets have been measured. The radiation spectrum contains intense maxima corresponding to vibrational transitions of the second positive system of molecular nitrogen N2 (C3Ξ  u β†’ B3Ξ  g ) and comparatively weak transition lines of the first positive system of the N 2 + ion (B2Ξ£ u + β†’ X2Ξ£ g ). By an example of inactivation of the Staphylococcus aureus culture (strain ATCC 209), it is shown that plasma is a source of chemically active particles providing the inactivation of microorganisms

    Get PDF
    The paper proposes a new atmospheric pressure plasma jet (APPJ) source for operation in air and nitrogen. The conditions for the formation of stable plasma jets 4 cm long are determined. Energy and spectral measurement data are presented. Β© (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only

    Infrastructure of Cultural Leisure in Consumer Society in Student View: Prospects and Problems of Promotion

    Get PDF
    The formation of the cultural leisure infrastructure structures the modern space in a special way and contributes to the formation of a new leisure sphere of modern society. The cultural leisure industry today is not only and not so much a training field, but a huge segment of the country's leisure market. The purpose of the study is to study the features of the cultural leisure infrastructure and its role in the representation of students. Research methods: as a research method, a questionnaire survey was used as a method of collecting primary information, which allows us to identify various aspects related to students' ideas about the ways and problems associated with spending free time. Research results: the article considers the role of leisure in the consumer society. The features of the development of leisure infrastructure are revealed. The novelty and originality of the study lies in the fact that for the first time the field of leisure is considered in the representation of students. It is revealed that leisure time for students is a criterion for identifying the status of a person, acts, as a social marker of a certain lifestyle, is a sphere of manifestation of different capabilities of an individual. It is determined that leisure is often aimed not so much at enjoying free time, as at filling the consumption of non-working time. For the first time, the reasons for the visiting of students in leisure studios are shown. It is revealed that there is a randomness of choice; the desire to find new meanings; a way of searching for oneself. It is shown that students note the leisure industry as a sector where, for a certain fee, the client buys not only the opportunity to spend time, but also new goals and ways of self-expression. It is determined that today leisure studios are not just a place where classes are held twice a week, but also a well-organized recreational space. Leisure studios are organized in such a way that a person who is engaged in, who is interested in it, feels that he belongs to a certain clan. It is revealed that the leisure industry sells not just services, but mood, and it is the leisure studios organized on this principle that are the most successful in the market of leisure services. From the point of view of students, an important role in the leisure industry is played by the teacher, as a guide to the world of hobbies. It is determined that it is the presence of a teacher that structures training in a special way. Practical significance: The data obtained in this work can be used in marketing research, economic sciences, advertising psychology, as well as for further theoretical development of this issue
