The article expounds a new method to build a quality control system for software design of the MPD experi-ment in the NICA collider. This software is called MpdRoot and is a shell to simulate the detector operations, toreconstruct the experimental data and analyse the events of heavy ions collisions. The author briefly describes software and technical side of the MPD experiment. A website content management system is considered as a platform for this project developers containing technical information about the project, a control version system, a testing system, a monitoring and others web-tools. The result is a complete system of quality control for MpdRoot software project. The article will be useful for software developers with a lot of members who would like to facilitate their work and improve teamwork.

The architecture of modern system on a chip K1867VTS3AF containing two digital signal processor cores, memory and a set of peripheral devices is considered in the article. Realization of communications between the personal computer and system on a chip using interface USB 2.0 is considered. The special software is developed on the assembler language for the SoC in compliance with requirements of USB 2.0 standard for communications with personal computer.The user software for OS Windows giving the user the opportunity toinitiate data transfers between K1867VTS3AF USB device and PC is developed. The driver of the K1867VTS3AF USB device for OS Windows is also developed.

Conflict systems form the research area of our study describingthe methods of protecting counterparty against research, as well as the methods of counteracting the protection against research. The study determines the researcher model in conflict. This model imposes information restrictions when trying to research the object of the conflict. The studyde-scribes four classes of the researcher depending on his information restrictions. The algorithm for designing systems protect-ed against research is also described. The counterparty research problem in a conflict system is that there is an opportunity of using this process to disinform. This is possible, if you knowresearcher's principles of interpretative work on information re-ceived, what gives you the possibility to reflexively control the opponent. Similarly, you can get the scheme to reflexively control the reflexive control process. At the moment the subject that really controls the process has information supremacy. To obtain this information supremacy, the subject has to get conflict's object under control that is sufficient to correct coun-terparty researcher model classes. By correcting classes of the researcher model, you can achieve the point when it becomes impossible for the counterparty to define the research objective. If the subject can get the process under control of this kind, than using the described algorithm it obtains information supremacy. We assume this algorithm can be effectively applied to information security software development. Using the considered algorithm, the analysis system of unauthorized user activity on enterprise websites and enterprise networks (ReflexionWeb and ExLook software) have already been developed.

54. Stochastic multi-agent model for the order book dynamics [№3 за 2013 год]

This paper introduces a stochastic multi-agent model to reproduce key empirical properties of the real order book dynamics. The model includes three mechanisms: sending limit orders, cancellation of limit orders and sending market orders. The empirical properties of the order book of RTS futures contract are used as parameters of the model. The sequence of order book events forms a Poisson flow. Order size has power-low distribution. The proposed model is able to reproduce several empirical features of the high-frequency dynamics of the orders in the book and price movements.

The article describes typical composition and modules of educational space center, their purpose and function-ality. It considers an educational module providing a theoretical and general space training of students combinedwith their practical training on virtual and full-scale space and flight simulators, as well as on interactive manned spacecraft analogues. Science module provides students with virtual simulators and booths sets to learn different experiments. The paper considers an interactive analogs composition of simulator module for their integration and future development of educationalspace centers. In the century of high technologies, the young people seek an additional education. Youth educational space centers will offer them unique programs, which are educational, informative and entertaining at the same time. If the equipment of these centers is like that, it will allow realizing innovative technologies in education. Creating new youth educational space centers in our country and abroad demonstrates the ways to integrate science, education, interesting leisure and theoretical bases development to design such objects will help to systematize accumulated experience and attract new ideas.

This paper presents personnel training problem formalization using visual environment simulation systems tools. This approach is used by engineers of Space Simulator Center when creating training tools for cosmonauts to workon the board of the International Space Station. The article describes basic approaches to using visual environment simulation systems in personnel training. The main task list for creating virtual training simulators is defined; the method of training ma-terial demonstration script definition using virtual reality terms; the method for saving trainee working results and examina-tion mechanisms based on control scripts are defined; the ways of searching error in trainee actions are described; themethod of attaching trainee results to mathematical modeling data of control processes is presented.

The solution of large elastic-plastic problems using finite element method requires solving large linear system with banded stiffness matrix multiple times. For a parallelsolution we used an adaptation of a LU-decomposition algorithm for dense matrices with 2d cyclic matrix distribution to the case of banded matrices. Compared to traditional algorithm for dense matrices, banded version of the algorithm stores only blocks that can have non-zero elements. This allows for the algo-rithm to have a significant reduction in memory requirements and in the same time makes it possible for the algorithm to have characteristics to reduce the volume and the quantity of inter-process communication like the dense version ofthe algo-rithm does. The algorithm performance was tested on a solution of an axisymmetric elastic-plastic problem of cylinder compression and a 3d elastic-plastic problem of tetrahedron compression. Efficiency analysis of algorithm was performed for regular grids of different dimensions. Solution was performed on the UMT cluster system of Institute of Mathematics and mechanics UB RAS. MPI was used for inter-process communication.
