The article describes definition of a new type of
crypto currency and innovative payment system. It
outlines the relevance in connection with the fact that
Bitcoin is gaining popularity. For the first time in
history Bitcoin exchange rate reached $ 4000 per
token. It is noted that despite the growing popularity
of Bitcoin, Russia's opinion about Bitcoin's official
status is ambiguous: Bitcoin is not officially
recognized, as a means of payment, and, at the same
time, as noted in the official report of the Central
Bank of Russia, is not prohibited. The main types of
fraud using of crypto currency are listed. The
negative consequences of the introduction of crypto
currency into circulation have been studied and
analyzed. The main advantages of Bitcoin are
described: it is easy to use, reliable; its system is
open and not subject to counterfeiting. The
possibilities of its use for the financial crimes was
analyzed. It describes positions of the leading
countries of the world in relation to the legal status of
Bitcoin. The main principles of the Bitcoin system
operation are summarized and systemized; the main
vulnerabilities and "weak spots" of Bitcoin are
described with examples of the most known crimes in
the world using virtual money. The BTC
vulnerabilities are described in the article. This data,
as well as a description of the main aspects of the
Bitcoin practical essence, can be applied in practice
as the basis for analysis to identify and prevent
financial crimes using crypto currency
In automatic devices, relay-contact circuits are widely used. The development and description of such schemes is quite a challenge. It is known that the apparatus of algebra of logic can be used with success here.
In the article the description of the elevator movement scheme is considered first in the usual way (as it is customary to describe in the instructions), then by the formulas of mathematical logic. A mathematical description of the movement of the cabin of a passenger elevator in the form of a logical function has been obtained
Semantic technologies provide existence of a certain abstraction layer over available information to technologies which allows realizing communication of data, semantics and processes executed in distributed environment. Development of these technologies will allow creating the unified representation of SWS in a wide range of applications, to find precisely necessary information, to simplify intra firm integration and integration of network applications in distributed environment. The article defines the semantic specification SWS, the tools for creating ontological Web services (SWS) and Web services (WS) at the conceptual level, defined requirements and assets of services composition. The architecture of SWS of applications, assets for deployment and execution of SWS by coordination of a flow of operations, network agents is described. It also considers the role of agents in creation and implementation service - the oriented applications, and also distinction between services and agents. Furthermore, the system architecture of integration of SWS with use of a multiagentny flow of operations is shown in article. It inspects the interaction between service and process agents with web services and distributed resources. In the article we have highlighted the advantages of the standard workflow management, portability and interoperability, strict formalization of the process description workflow and versatility. Based on the process of service composition using agent-based approach we have presented the future model of adaptive service composition based on the interaction of agents considered and architecture of multi-agent coordination. Step through the process of presenting service using agent-oriented approach was emphasized. On the basis of the process of service composition using agent-based approach we have presented the structure of the future model of adaptive service composition. Process of representation of service with use the agent-oriented approach is noted step by step. Based on the interaction of the agents we have considered a multiagent coordination architecture
The article considers the sequence of setting goals and objectives of the internal control of accounts receivable and accounts payable. Based on this sequence, the model of internal auditing payments to contractors in organizations of wholesale and retail trade has been made. The article also explains how to conduct this audit
The article contains basic assumptions of the region sustainable economic development model, which can be used to gain new knowledge about economic processes, contribute to the stability of the regional development, as well as serve as an educational tool
in the study of relevant disciplines
The article considers the model of granulometric
composition of foundry dust. We used the method of
particle size analysis, which is based on the dependence
between the size and the velocity of a body under the
action of gravitational or centrifugal forces.
Determination of granulometric composition of the given
sample of powder was made using the laser diffraction
method, implemented on a laser particle analyzer, Fritsch
NanoTec “ANALISETTE 22”. A model of dust particle
size distribution has been obtained
The article offers an account of our experience in organizing a new type of professional education called “included education” and puts forward the criteria for determining combinability of main and included education. Some of the advantages of included education over other forms of supplementary education are presented and substantiated
The study of the Russian-Slavic cultural, political and
economic links is quite actual nowadays. At the turn of
18 – 20 centuries Russia was the only independent
Slavic state that was a reason of special attention of
foreign countries. The most intensive contacts in
Slavic world can be found on a regional level. Both
pre-revolutional and modern scientists actively explore
such aspects as resettlement of Bulgarians to the
Kuban, places of their compact location, main
activities and further destiny of its members. There is a
detailed specification of colonization of Bulagarian
landowners from 18 until the beginning of 20 century
in the article, based on the archive documents. Also
described moments of first appearing of Bulgarians on
the Russian territory and particularly in the Kuban.
The article is focused on the main stages of economic
familiarization and adaptation of settlers to the natural
and social features of new locations. The conditions
and forms of vital activities in labor, lifestyle, sociopolitical
and cultural life that are typical for their social
relations are marked in the article. There is also noted
that main occupation of Bulgarian settlers was
horticulture, where they achieved greatest successes
thanks to mastery of artificial irrigation using a special
mechanism for that (a big wheel with attached
vessels); Hothouse economy, that allowed them to
produce thermophilic crops; organization of teams,
that assumed collective labor, labor relations and
mutual support. To sum up, Bulgarian settlers
harmoniously fitted into socio-cultural area of the
Kuban region
In the article, the essence of municipal business, feature of functioning of a housing-and-municipal complex reveals, and also the conditions for business development in housing and communal services are considered
The article basically formulates the problem of effective description of enterprise. We have offered and proved the possibility of using ARIS Toolset for processing description of enterprise for increase in efficiency of decision making
