PREDICTION OF THE ENTROPY VALUES OF LONG CODE SEQUENCES GENERATED BY NATURAL AND ARTIFICIAL LANGUAGES
Abstract
Calculation of entropy encoding letters long meaningful Russian by Shannon technically not possible with existing restrictions on computing resources. For example, biometric data is that the entropy of low dimension dependent code is related to the entropy of high dimensions exponentially. As a result, the entropy of long code sequences generated by natural and artifi-cial languages, described by a superposition of the exponent and the linear component. The latter allows you to easily assess the ultimate redundancy of natural and artificial languages.

SIMULATION OF MODAL BIREFRINGENCE OF STEP INDEX OPTICAL FIBER WITH MICROCRACK IN CLADDING
Abstract
This work presents model for birefringence components in step index silica single-mode optical fiber occurring due to axial dissymmetry by micro crack in the cladding. The expression for approximate estimation of mentioned component value is derived. We represent some results of estimations for standard step index single-mode fiber SMF28e.

INVESTIGATION OFNONLINEAR DISPERSIVECHANNELMEANSTENSOR ANDVECTOR ANALYSIS
Abstract
In work use a physical model of nonlinear dispersive link in a chain of cascaded linear and nonlinear inertial freewheeling two-ports. The possibility of such a model, the mathematical description of the functional matrix whose elements are functions of the input signals. On the basis of functional matrix constructed tensor model nonlinear dispersive channel in the form of multi-dimensional curved surface. The analysis of the properties of the model by means of vector analysis.Describes a method for optimizing signals using tensor derivative of the vector field outputs nonlinear dispersive channel.

THE MODEL OF FUNCTIONING OF THE ROUTER IN THE CASE OF LIMITED RELIABILITY OF COMMUNICATION CANALS
Abstract
The model of functioning of the router was developed and the influence of faults of com-munication canals on its reliability by the factor of serviceable condition probability was esti-mated. The metrics of reliability of the network, which applies different routing protocols, in case of number of communication canals with limited reliability and the intensity of their faults, were researched.

OPPORTUNITIES COMPARISON OF FRACTAL EEG-ANALIZING METHODS APPLICABLE TO DETECT CHANGES IN HUMAN BRAIN ACTIVITY AT DIFFERENT EXTERNAL LIGHTING
Abstract
This article discusses the results of practical application various methods of fractal deter-ministic chaos applied to the analysis of electroencephalograms (EEG). Was searched method for the differentiation of the state of the level of activity in the brain at different ambient light. The three methods used in the work: the method of false nearest neighbors, rescaled range Hurst and approximate entropy, a positive result was achieved only with the help of the ap-proximation entropy. Given to justify the use of these methods and discuss the results.

THE ESTIMATING THE QUALITY OF TELECOMMUNICATION SERVICE DELIVERY FOR TELECOMMUNICATION OPERATOR
Abstract
The methodic of quality estimating for telecommunication products delivery for telecom-munication operator. Its based on calculation all services, delivered into service layer agree-ment, and make apriority estimation for required resources with confidence interval. Interval summary value of resource-intensiveness, confidence interval and service layer agreement make required quality estimation.
