There are problems unsettled by manufacturers and installers of ventilation equipment during the design and definition of economy of its use connected with the absence of taking into account specific peculiarities of conditions for its operation and definition of reliable initial data for designing that causes errors during designing and unjustified expectations of a customer. There are obtained analytical dependences allowing the definition of reliable initial data for designing ventilation equipment with the recuperator of the heat of air removed for the specific conditions of operation in an engineering workshop. On their basis there is developed an algorithm for the computation of money savings taking into account actual energy consumption in value terms while overcoming aerodynamic resistances, a technique for the automated choice of essential equipment is also shown. The problem of the theoretical definition of incoming air temperature at the output of the recuperator Tin. air re. is solved. For computation automation there is carried out an approximation of data by mean temperature Tatm during diurnal hours Tatm day and nocturnal ones Tnoct. of the day for the last ten years for the eastern areas of Belarus and regression equations are obtained. The algorithm obtained in combination with analytical dependences for the definition of the condensate volume formed in the recuperator at the efficient arrangement of the ventilation equipment make a methodology for the complex approach at designing ventilation equipment with the heat recuperator for enterprises of engineering industry. The methodology mentioned allows designing a ventilation system for the workshop of an engineering enterprise in accordance with specific conditions of its operation it also allows defining a reliable value of economy of funds taking into account actual loss.

The analysis of Russian and foreign literature on the definition of somatic sex on the skull is presented. Cranioscopic and craniometric approaches are considered in carrying out craniological studies and existing traditional and modern methods for their implementation. Cranioscopic studies reveal the advantages and disadvantages of W.M. Krogman, G. Acsadi, J. Nemeskeri and V.N. Zvyagina methods. It is shown that the method of V.N. Zvyagina, which includes 40 descriptive diagnostic signs, is the most informative. Its efficiency is 93,5%. The comparative analysis of the craniometric methods for studying the skull according to R. Martin and H. Welcker in the modification of A.P. Bogdanov and a number of English craniologists is presented. The authors point out that the Russian Forensic Center developed a craniological form, which includes 79 different sizes of a skull, by which is possible to determine not only the sex of a skull, but also the approximate age of a person. A comparative assessment of the Russian (V.I. Pashkova) and foreign (E. Giles) craniometric studies is presented. According to V.I. Pashkova using only craniometric techniques allows one to determine the sex of the skull only in 75-80%, and in the complex approach - in 80-93%. The method of E. Giles, based on the study of regression equations, is objective in 83-86%. Thus, studies of the sex determination by skull in an adult should be comprehensive, including both cranioscopic and craniometric techniques.

In this Article I shall examine the visual form or appearance (shape, size, and other visible qualities) of Soviet socially produced things (excluding any detailed consideration of trends in the fine arts or of individual craftsmanship) in relation to forces in Soviet ideology which seem to have influenced this form or appearance. (I do not attempt to describe all influences which bear on Soviet design, which would require a much more complex approach and a more extended treatment.) My definition of Soviet “ideology” would be the same as Professor Meyer's: the body of doctrine that is taught by the Communist Party to all Soviet citizens. Whether or not this doctrine is true, or thought to be true, as well as why it is propagated, or whether this would be a complete definition—these questions are considered to be irrelevant in the present context.

Flexible queries have recently received increasing attention to better characterize the data retrieval. In this paper, a new flexible querying approach using ontological knowledge is proposed. This approach presents an FCA based methodology for building ontologies from scratch then interrogating them intelligently through the fusion of conceptual clustering, fuzzy logic, and FCA. The main contribution is the definition of the ontology rom classes resulting from a preliminary classification of the data and not the initial data. The data cleansing provides a simple ontology and an optimal research of relevant data taking into account the preferences cited by the user in his initial interrogation. To realize this approach, a new platform called “FO-FQ Tab plug-in” is implemented. This plug-in is integrated within the ontology editor Protégé to allow building fuzzy ontologies from large databases and querying them intelligently

Розглянута у роботі технологія дає змогу шляхомпоєднання переваг м’яких обчислень і реґресійного ана-лізу будувати багатофакторні залежності з неперерв-ним виходом, враховуючи як можливість визначенняступеня важливості вхідних змінних, так і їх взаємодійнеобхідного порядку. Проте під час моделюванняоб’єктів із неперервним виходом, коли необхідна до-статня точність визначення чіткого значення вихідноївеличини, знаходження параметрів нечіткого рівнянняреґресії за методом найменших квадратів та парамет-рів функцій належностей шляхом статистичної оброб-ки експертної інформації не може в повній мірі забез-печити потрібну точність. Для цього потрібно налаш-тувати за навчальною вибіркою нечітку реґресійну мо-дель у відповідності до тестуючої вибірки. In work considered technology allows to build multivariate dependence with continuous output by combining the advantages of soft computing and regression analysis, given the opportunity, the definition of importance of input variables and their necessary interactions. However, when modeling objects with continuous output when a sufficient accuracy of the determination of a precise value of the output value is necessary, the identification of the parameters of fuzzy regression equations using the least squares method and parameters of membership functions by statistical processing of expert information is not sufficient to provide the desired accuracy. It requires configuration on the training set of a fuzzy regression model in accordance with the testing sample.

The solar radiation climate of Greece is investigated by using typical meteorological years (TMYs) at 43 locations in Greece based on a period of 10 years (2007–2016). These TMYs include hourly values of global, Hg, and diffuse, Hd, horizontal irradiances from which the direct, Hb, horizontal irradiance is estimated. Use of the diffuse fraction, kd, and the definition of the direct-beam fraction, kb, is made. Solar maps of annual mean Hg, Hd, kd, and kb are prepared over Greece under clear and all skies, which show interesting but explainable patterns. Additionally, the intra-annual and seasonal variabilities of these parameters are presented and regression equations are provided. It is found that Hb has a negative linear relationship with kd; the same applies to Hg with respect to kd or with respect to the latitude of the site. It is shown that kd (kb) can reflect the scattering (absorption) effects of the atmosphere on solar radiation, and, therefore, this parameter can be used as a scattering (absorption) index. An analysis shows that the influence of solar variability (sunspot cycle) on the Hg levels over Athens in the period 1953–2018 was less dominant than the anthropogenic (air-pollution) footprint that caused the global dimming effect.

Throughout studying of a problematics of conscientiousness in article the question of legislative fastening of a category of conscientiousness from the point of view of various approaches is considered. Considering the complex approach necessary in questions of legal definition of the maintenance of this or that category, the author insists on introduction of concepts of conscientiousness, the diligent tax bearer, a presumption of conscientiousness not only and it is not so much within the limits of separate norms and articles, how many on necessity of reduction of maintenance НК the Russian Federation according to them. The legal regulation in such context when conscientiousness is a letter and spirit of the law, demands revision of set of its positions, concerning legal status of tax bearers, tax departments, tax agents, banks, a legal regulation of actions of tax control and consideration of their results, the tax information etc. Hence, for the author it is a question of giving to legal regulation of a certain orientation, a formulation new концепта, according to which: 1) the diligent person always has advantage before unfair, and the more so before the defaulter; 2) the diligent person cannot be put in the worst position, than unfair; 3) granting of tax privileges demands a recognition of the person the diligent; 4) application of special tax modes is put in direct dependence on a recognition of the person by the diligent. Thus, in a basis of legal regulation of a principle of conscientiousness the author puts the approach based on a recognition of a difference of legal status of persons depending on execution by them of a duty on payment of taxes that, in its opinion, to the greatest degree corresponds to taxation major principles — compulsions, generality, equality and justice.

To solve the applied task of detecting military assets in aerospace images the presented paper investigates the processes of constructing segmented maps of the images. The goal is to develop an information technique for detecting military assets in conditions of uncertainty of initial data. To achieve the goal, the following tasks were formulated: 1) to analyze usability of the existing segmentation methods for automatic detection of military assets in the images; 2) if the existing methods are inapplicable, to develop a new algorithm to solve the problem. In the paper the following methods are used: the methods of digital image processing, the methods of Boolean algebra and fuzzy sets, the methods of statistical analysis. The following results are received. Analysis of the known segmentation methods showed that due to camouflage coloring of the military assets, similarity of their color characteristics to those of underlying surfaces and due to the presence of large number of textured fragments in the images those methods provide segmented maps of poor quality. Among the common problems arising when conventional methods are used there are wrong segmentation, when the received contours do not coincide with the borders of the objects of interest; oversegmentation, when there are a lot of minor segments which produce "litter" objects; undersegmentation, when potentially possible segments are missed etc. As the conventional methods are inapplicable, in the paper it is suggested using the fuzzy logic systems. For each pixel the probability of the fact that the pixel belongs to the object or to the background is calculated. For making decision whether a pixel belongs to the object the production rules based on the chosen most significant factors (probabilistic values of spectral sub-bands, belonging of the neighboring pixels to the object, jumps of brightness in spectral sub-bands on the object's borders) are constructed. Conclusion. The suggested technique ensures high-quality definition of objects' borders, thus considerably increasing the reliability of military assets recognition.
