The electronic brain for intellectual systems and robots / V.O. Iashchenko // Mathematical Machines and Systems. – 2016. – N 4. – P. 3 – 17.
The technology of creation of the electronic brain for intellectual systems and androids is offered. Our solution of the problem of development of the electronic brain is the new architecture developed on the basis of a new type of the neural networks which do not have analog. On the basis of the multidimensional receptor-effector neural-like growing networks the theory and technology of development of systems with artificial intelligence is created. The technology is intended for creation of intellectual systems and robots of different function, and also for object management, having sensors and executive mechanisms. In the long term it is expected the receiving of full-fledged artificial intelligence. The purpose consists in realizing development of the artificial intelligence with new active, associative, uniform matrix structure for robots of various applications. It will allow creating robots assistants for the person which can understand the person and completely replace him in routine work or in dangerous places. The electronic brain can be used in any sphere of robotics, to be the virtual assistant in the normal computer or independent intellectual system. Figs.: 18. Refs.: 18 titles.

The architectural and structural organization of intelligent distributed memory system (IDMS) with hierarchical ring-bus circuits, which application provides parallelization of the algorithm for solving user problems in two or more levels is considered. It results in essential increasing IDMS productivity as a whole in comparison with the use of one ring-bus circuit. The main functions of constituting IDMS units and blocks are resulted and system functioning as a whole is considered. Preliminary estimate of application effectiveness of hierarchical ring-bus circuits as a part of IDMS is given. Tabl.: 2. Figs.: 3. Refs.: 12 titles.

Metamodel of the meeting lifecycle / O.V. Malyshev // Mathematical Machines and Systems. – 2016. – N 4. – P. 42 – 53.
Meeting is a traditional and effective mean of solving various problems. Like every phenomenon linked to human activities, the meeting has its own lifecycle, which simulation has scientific and practical interest. This paper proposes a metamodel of the meeting lifecycle, which, on the one hand, reflects traditional notions about it, and on the other, could serve as a basis for the development of appropriate automation means.

The content and structure of the client-server system of modeling the behavior of navigation and monitoring complexes of variable application / A.M. Kasim // Mathematical Machines and Systems. – 2016. – N 4. – P. 54 – 67.
The paper formulates topical scientific and applied task of creating a system that simulates the functions of collecting, processing and display of geo-referenced data about mobile objects and the correlated with them attribute data of cartographic background to solve the control and management problems of moving objects within the navigation and monitoring complexes of variable application. The solution of the task was carried out using a client-server technology to build software that underlies the functioning of the developed modeling system. The characteristic of the main components of the system, their interrelation and development tools are given. Much attention is paid to the description of the logical structure of relational databases of symbols of moving objects and cartographic background and organization of information interaction between the database server and the client applications that visualize the aggregated results of the processing query to both databases in the form of dynamic scenes. The proposed system can serve as a prototype for creation of effective navigation-monitoring complexes, and is also intended to form the basis for further research on this topic in terms of improvement or refinement of existing systems, taking into account the identified deficiencies in the interests of the entire range of users.

The results of research processes modeling of dialect texts within the multi- level information monitoring technology are regarded in the article. A new method of classifying text messages at the residence of their authors is proposed. The signs for classification got after decomposition of text and calculating their frequency characteristics.

It is proposed an alternative approach to the assessments of aggregation of key indicators of universities according to QS-version based on the application of fuzzy inference method. As the valued alternatives there were selected world universities ranked according to QS WUR first ten places on the list. By results of the calculations it is obtained other ranking of top-universities, which is somewhat different from the version of QS WUR based on the weighted aggregate assessment of key performance indicators.
