The architecture of the project, the basic structures and data types. The application of the language. The advantages of using VHDL in various stages of the integrated circuits design.

The main spheres of computer technology using. Development of structures for data management. File systems, characteristic features. Database Management Systems as a new stage in the development of a structured approach of storing and processing information. The structure of the database, its method of operation, the main purpose. Ways to ensure database integrity.

With the development of technology the problem of information security is becoming more extensive and serious. Major aspects and issues of information security, the priority areas in this field are overviewed. The term of “information security subsystem” is introduced and described. The logical structure and architecture of the subsystem data protection, its primary purpose and rules of construction are mentioned in the article. It briefly describes the basic methods of access control to resources, taking into consideration the credibility of the process, as well as the problem of process functioning.

Brief information about the term "information security " is given in the article. Multiplicity and complexity of the main challenges in this area, consideration of the basic state standards and regulations in the field of information security  are overviewed. Common history, their evolution in Russia and in the developed countries of the world, their basic tenets, goals, purpose are shown. The article touches upon the main standards as a basis for interaction between producers, consumers and experts on information technology training products and describes the importance for the introduction of uniform standards, concept and criteria, the benefits of such normative-legal base.

This article is devoted the problem of protection of audiovisual data in the popular ductings of connection. For the ground of actuality of this problem the row of basic tasks which must be decided was considered in its scopes, the features of application of vocal technologies are resulted in the systems of safety and informative systems, and also the market of services of connection was analysed taking into account the modern necessities of his users. As a result, it was exposed, that demand was lately increased on services of konferencsvyazi among the different layers of population, however offered modern technologies of defence  of vocal information for such multimodal systems in the indicated sectors of appendixes are not while.

Various blisk refurbishment ways are examined and the choice of the optimal one is performed in this article. The blisk refurbishment method allows the repairing of the damaged blade “on it’s place” is offered. That leads to improved refurbished component quality while reducing it’s cost. Schematic diagram of the refurbishment method is given

Market economy development, complication of organizational structure and growth of the majority of the Russian companies, the increased level of uncertainty, requirement for effective tools for overcoming of the crisis phenomena have caused necessity of working out of the given problem and adaptation of technology of management in cost to the Russian conditions. Unfortunately, until now in the domestic literature only theoretical bases of the concept of management in cost are considered.

The paper deals with analyzes and optimization of a tube mill with integrated straight edge forming stands using computer simulation

In this article there are various ways of the rework of the rack rail are examined and the choice of the optimal one is performed. The rework of the rack rail technique, allowing to degrade wear on 30% and the repair expenses of the kinematic pair “a worm – a rack rail”, is offered. Recommendations about the repair of the rack rail by means of a composite material RЕКОМ are made.
