Certification centres as the infrastructure of modern information security and digital barriers

.

Abstract

The paper analyses the most important problem in the area of information connected with new administrative barriers – digital barriers which came into existence due technological and organizational mismatches. Several types of digital barriers are isolated: impenetrable, borders between different departments, between Russia’s regions and international digital borders.
Ways of overcoming existing barriers are proposed.

Evaluation of changes of gas parameters in a vessel when its wall is broken through by high-velocity mechanicak particles

1 1., 1 1., 1 1., 1 1., 1 1., 1 1., 1 1.

Abstract

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.

Mathematical model of system heating by a moving slayer in case of plazma slaying

1 1.

Abstract

A procedure of calculating temperature distribution across the flat system coating-base has been developed. The procedure involves plasma spraying and takes account of plasmatron motion and coating build-up. It is shown that the temperature in the near-surface layer of the coating sprayed during plasmatron passage can considerably exceed the temperature magnitudes in the lower layers.

Formation of factor – coordinated complete supply mechanism of interaction in the «customer-supplier» system

1 1.

Abstract

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.
