Abstract: the article discusses a hierarchical approach to the analysis of the complexity of parallel computing process implementation. The authors introduce the concept of elementary homogeneous and elementary heterogeneous computational processes on which the analysis of the heterogeneous branching parallel processes and heterogeneous computational processes is based. The article shows that complex parallel process and heterogeneous computational processes can be represented in the form of discrete Markov processes of a special type. This approach allows to transform such processes to a classical discrete Markov processes with a consecutive change of states.

Abstract: this article considers the methodology of semantic models designing for one of the most important classes of intellectual systems – intellectual reference system. The methodology is based on use of semantic networks for encoding the information stored in knowledge base. The method is built on two principles: the principle of evolutionary design and the principle of collective design. A distinctive feature of this approach in designing intellectual systems is that at the each step of the designing process a working prototype of the system is available, which speeds up putting the developed system in operation both for testing and end-users and significantly increases the life cycle of the product.

Abstract: the article emphasizes the need for a new knowledge representation model for increasing the efficiency of the expert diagnostic systems in social and technical fields of study. The authors present a fuzzy-production model, which allows the rules of the field of study to be described on a set of data of different types, represented both in clear and fuzzy scales. The authors develop a methodology of grouping the parameters, describing the object of diagnostics, to construct the cascade of parameters in accordance with the stages of the diagnostic process. The cascade of production rules is build upon the base of given model and method allowing to diagnose the state of a complex object. The authors describe the algorithm of a logical conclusion on the cascade of rules. On the solution of the medical diagnosis problem the author shows the effectiveness of the proposed approach, poses the problem of the future studies.

Abstract: 3D-record of a lesson is a powerful tool for education in virtual worlds. However, as with the video records, the 3D-record needs to be edited by the teacher to turn into a high-quality educational content. As opposed to a video stream a 3D-record is a complex sequence of changes of synchronized properties bound to the timeline that starts from the beginning of the lesson. 3D-record editing capabilities require solving number of technical problems related to the size of the original data, removing unnecessary resources, speed of the record replay and the size of the network packages. The article is devoted to these issues.

Abstract: the presence of the DSP-block and a large number of I/O ports in modern FPGAs allows to use them for a successful synthesis of the digital signal processing algorithms. The system of residual classes involves multithreading of computations, thus FPGAs are very well suited for the implementation of these algorithms, since the computations in the channels of the system of residual classes are carried out in parallel and independent from each other. It is known that the FPGA is a microchip, the logic of which is not determined on creation but is set up by programming in specialized software, such as Quartus II. Developers of the special processors DSP are highly interested in the realization of FFT using the system of residual classes on FPGA Altera Cyclone II. The article shows the results of the development of the conriguration file for realization of FFT using the system of residual classes on FPGA Altera Cyclone II in the development environment Altera Quartus II using the Verilog language of the hardware description. The author describes the FPGA work under the developed configuration file. The article presents timing characteristics and estimated calculation errors.
