The model of an optimization problem, which allows us to determine the optimal structure of a wind power system, was stated. The constructed optimization problem includes the objective function, describing the dependence of efficiency of a wind power system on its structure, and constraints that imply integer design parameters and demand for providing the assigned capacity of the WPS. In the process of solving the stated problem of integer programming, we determined the rule of division of a set of solutions into subsets and the computational criterion of assessment of the upper bound of each subsets, which made it possible to apply the branch and bound method, which allows us to find the optimal solution at minimum computational costs.The software system for solving problems of integer programming with the use of the branch and bound method was designed and implemented. The structure of a software system, based on a modular principle, which provides quick modification and improvement of the application in the process of its development, was built. In the process of implementing a software system, the dataware was developed, based on the doubly connected list data structures and allowing us to process efficiently large arrays of information. For effective organization of data exchange with existing software systems, the XML format was used. The results of application of the developed software system with the use of the branch and bound method to determine the optimal structure for a wind power system were presented.

The level of accuracy of author attribution of a text is not high enough at the lexical and syntactic levels of a language as these levels are not strictly organized systems. In this study, the author attribution of a text is based on the differentiation of phonostatistical structures of styles. We have developed a system of differentiation of phonostatistical structures of styles, which differs from the existing ones by the chosen level of a language ‒ phonological. At this level of a language one can obtain results with a greater accuracy. In addition, the system constructed is based on a modular principle, which makes it possible to rapidly modify the developed software. We have developed methods and models that are based on the theory of mathematical statistics and allow the improvement in the accuracy of differentiation of phonostatistical structures of styles. A method was devised for a comprehensive analysis of phonostatistical structures of styles, as well as a multifactor method for determining the degrees of action of factors related to style, substyle, and author's manner of presentation. We have constructed a statistical model of stylistic differentiation using the ranking method, and a statistical model for determining a general stylistic markedness of the examined text. A software system for the differentiation of texts was designed. The criterion for the differentiation of texts is the mean frequencies of groups of consonant phonemes. In the process of implementing a system we used the programming language java, which ensures that the software is platform-independent. This study reports results of the application of the developed methods, models, and software tools. The research results confirm that author attribution of a text at the phonological level is more effective. The developed methods, models, and means for the author attribution of a text could be used when determining the percentage of creative contribution of each of the co-authors of scientific papers.

The system makes it possible to analyze vibration parameters in order to predict and prevent possible accidents, thus reducing the costs associated with the failure of the cutting tools, expensive parts and assemblies of the CNC machine

Present work examines a contribution of the membrane thermodeflection to the temperature error of a tensoresistive pressure sensor when measuring under conditions of non-stationary thermal effect. The study is based on an analysis of the temperature field in the membrane during thermal shock. It was found that during thermal shock one observes gradients of temperature field by thickness and radius of the membrane. It is shown that the combination of these gradients generates a thermodeflection of the membrane. It was established that at such thermodeflection relative deformations on the membrane surface can be comparable with the working ones when measuring pressure. Thus, it is found that the thermodeflection is a significant factor for an increase in the temperature error of sensor. The research revealed that by minimizing heat exchange on the perimeter of sensor membrane it is possible to eliminate the gradient of temperature field along its radius. By so doing, it is possible to minimize the thermodeflection of membrane and decrease temperature error of the sensor. It is proposed to minimize heat exchange on the perimeter of membrane through the thermal insulation, or by a special selection of parameters and materials for the casing of the sensor and the membrane.
