PROBABILISTIC METHODS OF INFORMATION MODEL BUILDING FOR THE EARTH ROTATION IRREGULARITY
- I.N. Sinitsyn IPI RAN. email@example.com.
Abstract: New linear and nonlinear probabilistic methods of model building for fluctuation of the Earth irregularity are
considered. Methods are the basis of a priori data processing for the problem “Statistical Dynamics of the Earth
Rotation.” Test examples are provided.
Keywords: information model; information resources; linear and nonlinear probabilistic methods; hereditary;
fluctuations; one- and multidimensional distributions; asymmetry; excess; Gaussian and Poisson white noises;
distribution parameterization; moments methods
ELASTIC DEFORMATIONS IMPACT ON FINGERPRINT RECOGNITION PERFORMANCE.

Abstract: Elastic deformations are the strong negative factor in fingerprint recognition. The mechanical approach to fingerprint
deformation modeling was employed to determine elastic deformation impact on fingerprint recognition. The
statistic analysis of structure of elastic deformations was carried out. It revealed that an arbitrary deformation is the
combination of elementary principal deformations: rotation, torsion, and traction. Finally, numerical measure for
the impact of deformations on fingerprint recognition was found.
Keywords: fingerprint recognition; nonlinear distortions of fingerprints

Abstract: The models of packet switching network with repetitive transmissions for two schemes of buffer memory distributions
— complete sharing and complete partitioning — are considered. The iterative method of calculation

The necessary condition for existence of solution of stream balance conservation
equations in steady-state regime was established. The monotone convergence of stream intensities sequence and
probabilities of blocking derived in the proposed method to the solution of these combined equations was proved.

Abstract: The paper is a next step in bayesian queueing and reliability models investigation. The method provides the
randomization of system characteristics with regard to a priori distributions of input parameters. The new results
are presented for two cases when both a priori distributions are Erlang distributions and when a pair of a priori
distributions is the pair “Erlang distribution –degenerate distribution.”

Abstract: The single server queue with time-dependent Erlangian input is considered. The service times have general
distribution. The asymptotic behavior of the queue length with traffic intensity less than 1 and with arrival rate
weakly depending upon time is investigated.

Abstract: The Prawitz’ asymptotic estimates for the absolute constant in the Berry–Esseen inequality are sharpened for
the case of independent identically distributed random variables with finite third moments. Similar estimates are
constructed for the case of unbounded third absolute moment. Also, upper estimates of the asymptotically exact

Abstract: The technology of storage of poorly formalized documents that are created using lexicological synthesis is
considered. The technology provides formation of the kept index sequences containing indexes of document forms
and their substantial components. Additionally, thanks to simultaneous preparation of documents and creation of
kept index sequences, the economy of time is provided. The experiments have shown the efficiency of the approach
