The purpose of this study is to develop software to conduct research on the effectiveness of the parallel ant colony optimization algorithm applied to the shortest-path search. The algorithm is based on the behavior principles of an ant colony as well as individual ants, who search the shortest path to the food source. In order to study the effectiveness of the ant colony optimization algorithm one of the most common optimization problems was applied, specifically – a travelling salesman problem. The algorithm shows its efficiency and stability only on the sufficient amount of resources. Its resource usage and therefore the working time grows rapidly together with the growth of the size of the task. In order to solve this problem the parallelism is applied. It is also вused to reduce the premature convergence to the local optimum, as well as to stimulate diversity and search of the alternative solutions of the same problem. In the proposed software each independent ant colony is developed on the separate computer core. Each colony exchanges the best individuals with other colonies in a certain number of generations. The topology of this interaction has the form of «each with each». According to the calculations, we can conclude, that the efficiency of the ant colony optimization algorithm does not change with the increase in the number of kernels (individual populations). However, there is a slight change of the reliability of the particular settings. But at the same time we can observe the substantial increase in operation speed. Thus, the parallelization of the ant colony optimization algorithm can significantly reduce the execution time of a software application without compromising reliability. The ant algorithm is used to solve complex optimization problems. Typical areas of the algorithm application include scheduling, resource and job allocation, transport routing, etc. For this reason, the problem of increasing the efficiency of the algorithm calculations is quite topical.

This paper proposes methodological aspects of evaluation of organization efficiency of personnel management and motivation on the bases of application of economic and mathematical tools by implementing a three-component algorithmic model. The structural divisions heads’ work effectiveness evaluation is carried out on the basis of econometric systems of structural equations that allow you to rank personality, communicative, innovative, social and corporate managers characteristics that have the greatest impact on the overall performance indicators of the bank staff among which are considered amount of attracted funds; assessment of employee's compliance with the standard; activity efficiency (number of contracts); contribution to development. The obtained modeling results confirm the hypothesis that structural unit managers need to work on the development of their communicative, innovative, personal and social characteristics. Models for analyzing the personnel motivation factors on the bases of the methodology of multivariate statistical factor analysis with initial list of 13 main indicators of staff motivation are proposed; as a result, we set up the aggregated factors that reflect the properties of several motivational components such as financial, social incentives and medical insurance for employees. The model for estimating influence of motivation factors on results of bank's activity on the bases of nonlinear econometric functions is constructed. The regression equation of the motivation factors influence on the bank total profit is obtained. The proposed model toolkit for evaluation of efficiency of management and staff motivation will allow the bank's management to improve motivation and incentives mechanisms in order to raise efficiency of stuff productivity in direction of increasing bank profitability and competitiveness.

This article focuses on the choice of the optimal way of converting MIDI music files into musical notes. MIDI(Musical Instrument Digital Interface) is a standard for transmitting information between electronic musical instruments. It was developed in 1983, which makes it possible to communicate electro music instruments, computers, and other MIDI-compatible equipment, carry out one management tool for others. MIDIdoes not transmit audio information, but it works with "messages," such as the height and dynamics of the notes on the instrument, control signals for parameters such as volume, panorama, timing signals for tempo synchronization, etc.MIDIis marked by an extremely widespread. In this article, an algorithm of receiving musical notes fromMIDImusic files is implemented. The algorithm works fast, allowing the musicians to convert any melody into a noted instrument with the possibility of printing in real-time. With the development of the technology of musical programming arose a new object-in method of studying creativity. It calls modeling (reproduction or imitation) of some aspects of the objects studied or processes. It gives you the ability to start learning a musical instrument because you can simulate the process of playing any melody in the application. It is convenient for professional musicians because of the availability of music notes from music files with the ability to adjust tonality, time signature, duration, playback speed, with the possibility of transposition and modulation, etc. The developed software allows to get a musical interpretation of any melodies in MIDI format in real time with possibility to simulate playing these melodies on a musical instrument.

A method for numerical simulation of the hydrodynamic parameters of a gas-liquid medium with allowance for its weak compressibility is proposed. Application of the method is illustrated by the example of the calculation of the hydrodynamics of a melt in a ladle during its filling and the blow.

Our experiences include 124 patients (women) aged 25-50 years. Microsclerotherapy was used with 0.5% solution of etoxisclerole and 0.2% solution of fibrovein. The compressive microsclerotherapy proved to be an effective and harmless method of treatment of telangiectasias giving good cosmetic results and arresting clinical symptoms thus improving quality of life.
