The main line of work is developing of specific low-level software for synchronizing data structures
between file system and clients. The data represents the logic of BML that also developed by author.
The language stores their logic in the XML-like structure that has elements and properties. One of the
elements is «Set» that associates with a table in a relational database. And element «Block» associates
with a field of some data. The main difference is in the extended nature of elements. So, Block can
have specific data type and Set can have relations between other sets. When BML developer modifies
the source code it causes problems with database rebuilding. The modified project can produce a high
load in the system. So, that process should be distributed by the child process. On the other hand, there
is second problem related with constant reading of filesystem data. So, synchronizer should perform
also file caching function. Synchronizer through the specified interval checks any modified properties
like date or checksum of files in the working directory with BML and totally reloads logic structure
data when such changes will be. Author also proposes using of non-blocking sockets for interaction
with clients. Necessary data transmits through BSON (Binary JSON) and they should be interpreted
by each client that receives it. In the article author made a complex architecture of low-level software
and proposes some non-standard solutions.

During a Unity3D-based application development arose a problem of the best approach to a modular
architecture. Main requirements were extensibility of a system via plugin mechanism, good performance
within single main loop, aggressive garbage collection tolerance, low memory footprint and
minimal amount of allocations. Event-driven architecture has been chosen as the one fitting the bill.
This paper describes three different approaches to a message exchange within such an architecture,
their relative ease of use, ease of maintenance and performance. Message exchange mechanisms being
reviewed are: C# native events, event manager with event and publisher types tracking, static events
lists with responsibility demarcation and tight IDE integration. All three methods are supposed to be
used inside Unity3D version 4 hence being single-threaded and .NET 3.5 compatible. In the end static
events lists approach has proven itself although a little bit more verbose than the two other methods,
however the best one in terms of performance and IDE integration. The best thing about the selected
approach is the fact that it shifts considerable part of an abstraction overhead into an application compile
phase rather than runtime. Considering all being said static events lists approach is the best one
to use within Unity3D applications.

In an article written based on the report on the X-th International Scientific and Practical Conference
«Object Systems — 2015» (Rostov-on-Don) describing the approach to design database structures
and reflection the computational models in the ‘’meter-to-cash systems’’. In this article to presenting
a new definition of the concept of «calculation model». In an article, describe the basic properties of
object-relational of computational models, and proposing a model of the database structure meter-tocash
systems in power retail companies.
The hierarchy is based on a relationships makes it easy to describe such a model mathematically to
form the terms of reference for the development of meter-to-cash systems.
The proposed approach of the author of the structural and parametric synthesis of technical systems
power supply to consumers in the retail electricity market allows formalizing the various functional
elements according to this system. This approach shows how the various of connection, the catalogs
and tables, to form the computational model, which describes the electric power system in the
physical sense.
Presented in the article the way of formalizing the concept of «calculation model» provides the theoretical
foundations of the development of methodology for the design, development and maintenance
of information systems of the subjects of the retail electricity market.

In article it is offered to divide a set of the problems of representation of knowledge (PRK) in computer
systems into the tasks which are put forward to the decision from knowledge engineers and the
tasks which are put forward from developers of covers of the systems founded on knowledge (SFK).
Then for the researches of PRK which are put forward from developers of covers of PRK systematization
is offered and realized. Isolation of the selected researches to the scientific direction (SD) is applied
to systematization. That is, the main characteristics of new SD are created and formalized: object,
subject, purpose, methods and research problems. For each characteristic the definition is formulated.
At the identification and the description of methods of researches of new SD it wasn’t succeeded to
reach necessary specification. However consideration in article of the concrete practical works which
are already executed within new SD allows successfully (but intuitively) to realize the applied methods
of researches. The isolation of SD is executed and described in the article «Representation of
knowledges in computer systems» can and has to become the activator of conscious and purposeful
researches on creation of sound theoretical basis for the solution of PRK.
The material statement in the article is constructed in the form of dialogue with the opponent. And
versatility of consideration of a problem on article subject is provided to these. The opponent chose
some earlier not studied essence, corresponding it is offered to them to call concept «the virtual admirer
». On each of the stream of sophisms which is put forward by the virtual admirer in the article
the explanations opening purposely wrong selection of starting positions are given.

Comprehensive, accurate and qualitative information is the basis of research, decision-making and
management activities at different levels and applications. The non-trivial cases to obtain data related
to the solution of complex problems and requires establishing special data collection or monitor system,
the traditional approach to the construction is based on pre-formed requirements derived from
system analysis stage. However, the actually observed processes due to their unpredictable character
are typically different from expected ones having highly variability of their parameters’ values and
behavior styles thus reducing the originally built monitoring system efficiency because of ever-growing
discrepancy between the initial objectives and actually observed environment. The solution may
exist in creating a system of adaptive monitoring, featuring flexibility to change its structure and behavior
depending on changing conditions. The paper describes the fundamental concepts for building
systems in an adaptive manner taking into account and generalizing the accumulated experience
of implementing this approach. We indicate the possible adaptation areas, describe the main system
components and objects, such as triggers and indicators, enumerate the requirements they should meet
and enlist the recommendations for their design. In addition, the possible IT technologies, platforms
and application systems examples that implement an adaptive monitoring approach are highlighted.

This article is about efficiency assessments and decision support tools for geographical information
systems. In this article described new suggestion and solutions of the decision support problem in the
sphere of applying geographic informational systems and the way they used in busyness-process management.
Authors suggest using busyness-processes models with a GIS tools in order to provide information
about result forecasts and resource use efficiency to the one who make a decision. Prototype of
the system, which implements all of these suggestions, were developed by the authors and described
in the end of this article. Key feature of this system is represented by idea, that planning in terms of
tasks and operations can’t clearly show the real situation, where all actions are connected and use the
one single scope of resources (human resources, technical resources, materials, documents, e.t.c). In
other words, planning should be performed in terms of business processes and business process resources.
In that way, experts and planning-tool users could be provided with enough information about
resource using efficiency and predicted results (forecast) in order to achieve higher level of the decision
support for users. In this article authors describe an example of the agriculture planning using
business-process models and ontological knowledge base.
