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.

Method of designing a semantic model of the intellectual reference system based
on the semantic networks
// Software systems and computational methods.
2013. ¹ 1.
P. 56-68.
URL: https://en.nbpublish.com/library_read_article.php?id=62449
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

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.

// Software systems and computational methods.
2013. ¹ 1.
P. 129-133.
URL: https://en.nbpublish.com/library_read_article.php?id=62455
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.
