EXPECTED PROFIT OPTIMIZATION OF CONSULTING COMPANY USING THE METHODS OF DYNAMIC PROGRAMMING
DescriptionThe article presents the methods of specialists’ distribution for a consulting company between its projects in accordance with the methodology of dynamic programming for expected profit maximization. For its implementation, a mathematical model is being formed with nonlinear objective function and linear restrictions. The non-linearity of the objective function is due to the specifics of consulting companies and their size. The model includes probability parameters determined by expert evaluations method based on previous experience of the company in the analogical works and describing successful implementation of each project in its portfolio. Then the parameter and function of the state, satisfying recurrence are considered and linear replacement is performed to reserve a minimum number of experts on each job. The article gives a hypothetical example of a consulting company, including in its portfolio five projects with the mentioned profits in case of their success. On its basis, the developed method is implemented as a 5-step procedure of modeling of unknown parameters. Economic impact of the methods’ application is estimated . The developed model and method can be used by specialists in consulting companies, as well as in service industries

Description
The article substantiates the need for an accelerated informatization of the national system of professional development for science-intensive and high-tech industries, as one of the important components of the process of reforming the Russian economy. It was determined that under current conditions a decisive role in ensuring the successful operation of enterprises science-intensive and high-tech industries provides highly qualified personnel - the intellectual capital, which is formed in the process of training specialists within the system of continuous professional education and training (CPEandT). We show new capabilities of training a contingent of specialists in science-intensive and high-tech industries, offered by the introduction and expansion of use in system of CPEandT and modern educational technology (MET). We found reasonable prospect of the transition from reproductive to creative model of the organization of skills development. They are implemented mainly by a variety of electronic educational resources (EER), which are used for the development of various technologies. The article presents results of the comparative analysis of new and traditional technologies for the development of ESM and shows their role in the methodical maintenance of process of professional development. It is proved that the introduction of the EER within MET in CPEandT system radically changes the interaction of professionals and qualified teachers with contingent specialists of science-intensive and high-tech industries, and contributes to the effective organization of skills development

MODELING OF MODERN TRENDS IN RISKORIENTED AUDIT WITH THE APPLICATION OF BAYES THEOREM
DescriptionThere are many ways to improve the decisionmaking process, but, with a big amount of data and complexity of decision-making trees, it's becoming more and more complicated to keep up with the flow of information coming from many spheres of modern life. Therefore, the development of various problemsolving approaches has become an important step in changing the face of existing technological systems. This idea appeared in the work of an American scientist J. Perl who, in 1988, founded a new probabilistic approach to artificial intelligence and developed principles of Bayesian Network. Bayesian Network is a graphical model that represents a set of random variables and their conditional dependencies. In the article, the most valuable parts of the given topic have been reviewed, cognitive maps have been compared with their partial manifestation - Bayesian Network; also, one of the options to practically use such models in the audit field has been analyzed by observing a possible decision-making process of giving a modified or unmodified opinion

NON-PARAMETRIC CYCLES ESTIMATORS
01.00.00 Physical-mathematical sciences
DescriptionIn many applications, we study the time series (or a random process), which is the sum of the periodic deterministic function of time and random errors that distort the periodic signal. It is required to estimate the length of the period and the periodic component. It does not assume that the periodic function is included in any parameter family of functions, such as finite sums of sines and cosines. It is obvious that the assumption of occurrence of a periodic function in parametric family does not meet the characteristics of the real world, ie, is conditional, internal mathematical (look for the keys under the lamp because there is a light, not in the bush, where lost, because there are dark). For similar reasons, it is impossible to assume that the distribution function of the random errors is included in any parameter family of distributions. In accordance with the new paradigm of mathematical statistics in this article we studied the problem of nonparametric estimation (minimum) length of the period and the periodic component of the signal. On the basis of natural variation and scope of indicators is suggested a new class of nonparametric estimators of the length of the period and the periodic component in the time series. Based on the general results of statistics of objects of non-numeric nature we proved the consistency of these estimates. From the practical point of view it is necessary to minimize the numerical (one parameter - ability length of period of time) one or more of the 66 functionals, described in the article

NEW DESIGNS OF COLUMNS, INHABITED, INDUSTRIAL AND ADMINISTRATIVE BUILDINGS
DescriptionOriginal screw designs of buildings and columns are offered. Frameworks of these buildings and columns are the bearing elements and means of external and internal decoration of buildings and constructions. Originality of such buildings and columns frameworks is ensured by the fact that their design is decorated on the outer surface with broken or smooth screw edges and screw surfaces. Versatility of the offered screw columns trunks designs, as well as the possibility of performance of their left or right screwing allows reaching certain symmetry or their repeatability in the form of harmonious alternation of the bearing trunks of screw columns and spaces between them. Giving to numerous sides of trunks of screw columns of a certain invoice, or their coloring in different colors, will contribute even more to their expressiveness and beauty. Durability and vibration resistance (including seismic) of such trunks of screw columns at the same volumes of construction materials, in comparison with round and rectangular trunks is higher

ABOUT A VARIETY OF MEDIA GENRES IN MODERN RUSSIAN AND FOREIGN JOURNALISM
10.00.00 Philological sciences
DescriptionThe article deals with media genres in Russian and foreign journalism in the conditions of modern realia. The researches of this sphere find some reasons, caused by different approaches and criteria existing in different language systems as in Russia, as in abroad. The author of the article has been studying scientists’ works to point out some definitions of genres. In Anglo-American journalism genres have the category of sub-genres, including news report, the news interview, or the news headline. It is also pointed out that with the development of new information technologies many journalistic genres loose its timeliness. They are sketch, satirical article, editorial, press review, other (interview, comment, essay) – in the contrary, increase its existence. New genres are noted, among them are journalistic investigation, confession, version, conversation, press release. In spite of the variety of genres, theorists note their irregularity and migration from one sphere into another (lecture, debates, cross examination). Among all, there are new genres such as Rapinfo – news in patter and fatics which helps to contact with reader, forge and boost links with audience

DescriptionPeculiarities of breeding oidium-resistant genotypes in crossing Crimea autochthonous grape varieties with complex interspecific hybrids were studied. Twentytwo populations consisting of 1323 seedlings were analyzed over a period of 2008-2014. The highest oidium resistance was registered in the progeny of the cross Khersonesskii х ЖС 26-205 (6.8 points), and the average estimate of oidium resistance across all the study populations was higher than that of the initial autochthonous grapes of the Crimea. The level of hypothetical heterosis in the majority of the study populations indicates that, on the whole, the hybrid seedlings possess a higher oidium resistance relative to the initial Crimea autochthonous grapes. The highest breeding value was associated with cross combinations having the complex interspecific hybrids Muscat JIM, Spartanets Magaracha and Magarach 31-77-10 in their pedigrees. The cross combination Muscat JIM х Shabash was the most efficient, yielding 10.7 per cent of oidium-resistant seedlings. It was reliably established that a high level of the genotypically determined inheritance of oidium resistance is found in crosses with the participation of the interspecific forms Magarach № 31-77-10 and Muscat JIM (female parents) and Spartanets Magaracha and Tsitronnyi Magaracha (male parents). The expediency of this direction of breeding research was proved

Description
The article examines the historical conditions and the legal regulation of the Crimean Khanate territory joining to the Russian Empire in 1783 and formation of Taurian District as a new specific administrative and territorial unit. Specific characteristics of Taurian District are highlighted, as well as tasks that region faced due to its geographical position and constant wars between Russian empire and Ottoman Porte. Attention is paid to the factors that led to the creation of the district but not the viceroyalty, in contrast to other areas joined in the same time. The different examples of understanding of the term "distrist" – "oblast" – in science and language are given. The author clarifies certain features of the district, which were not taken into account in deriving the scientific definition of the district by Dambaeva O.P. Decrees and their background issued by the legislator are characterized. The problems of an administrative nature encountered by the legislator in the face of Empress Catherine II and her representative governor Grigory Potemkin-Tavricheski, and then by Platon Zubov are highlighted. Among these problems there were emphasized the transfer of ownership of the Tatars property who left the territory, as well as the creation of an accurate map of newly joined territory
