Issues of technological protection of information and software of complex technical systems.
Methods and mechanisms of maintaining the efficiency of a complex system in case of failures are proposed. The technology of ensuring its efficiency is also proposed.

The paper considers the economic aspects as the main constituents in the system of the country’s national security.
“Indicators” of economic security are analysed. Concepts and categories used to assess the security of society and state are described.

The problem of improving, developing and realization of national security is dealt with. New methodological approaches to providing national security are shown.
The definition of national security subject concept is given, which integrates the individual, the society and the state. External internal threats to the national security of Russia are discussed. A systemological approach to developing and solving problems of ensuring national security and their realization is described.

The paper presents a survey of space facilities of Earth distant probing produced at the State research–and–production space-rocket centre “TsSKB-Progress” in the 1970s – 1990s. technical characteristics of EDP space vehicles and the main directions of their modernisation are given. Ways of obtaining space information and the results of applying it in national economy are discussed. Prospects of development of EDP space facilities at “TsSKB-Progress” are specified.

Mathematical heat exchange models of a cold accumulator nozzle and photoreceiver of spacecraft supervision equipment are developed. Basic calculation formulas are given. Issues connected with determining thermal characteristic of cold accumulators of spacecraft airborne cryogenic cooling system are discussed.

Simple methods of evaluating gas parameters in a vessel whose wall is broken through by high-velocity particles are suggested. It appears that in case of non-catastrophic destruction of the vessel wall the changing of the parameters of non-excited part of the gas during the time the particle, its fragments and fragments of the destroyed front wall of the vessel more to its back wall is negligible. Relationships for calculating pressure on the back vessel wall are given for four peculiar modes of vessel front wall destruction. The data can be used, in particular, to evaluate the vessel back wall destruction.

The paper presents a complex of measures aimed at improving acoustic comfort and reducing noise level in the salon of VAZ-1118 “Kalina” automobile. Results of experimental assessment of the proposed complex of measures are given.

A simulation system for road traffic control is introduced. Algorithms of local and coordinated control are described. An average delay of a vehicle at a crossroad was chosen as the basic optimality criterion.

The paper deals with the formation of a factor-coordinated mechanism of interaction between a customer and a supplier. Completing items supply is taken as an example. The author proposes to carry out coordinated interactions by changing contract prices of completing items so as to make a supplier interested in meeting the customer’s requirements accurately. Conditions characterizing the lower and the upper margins of changing contract prices are shown. The condition of economic expediency of realizing coordinated interaction is also introduced.
