- A.M. Tursunbayev. Department of Mathematical Statistics, Faculty of Computational Mathematics and Cybernetics, M.V. Lomonosov Moscow State University
Abstract: Median modofications of EM- and SEM-algorithms are proposed for separation of mixtures of normal distributions.
The advantages of the proposed algorithms over standard methods are illustrated by the numerical solution of the
problem of decomposition of volatility of financial indices.
Keywords: separation mixtures of probability distributions; robustness; efficiency; EM-algorithm; SEM-algorithm;
volatility
SPLITTING OF DISTRIBUTION MIXTURE IN TWO COMPONENTS
- M. P. Krivenko. IPI RAN. mkrivenko@ipiran.ru
Abstract: The problems of splitting the distribution mixture in two components and of estimating mixture parameters are
examined if samples from distribution mixture and from one of components are presented. Two methods of
parameters estimation are suggested, as well as corresponding algorithms are constructed and examined.
Keywords: mixture of normal distributions; splitting of distribution mixture; EM-algorithm

- V. Yu. Korolev. Department of Mathematical Statistics, Faculty of Computational Mathematics and Cybernetics, M.V. Lomonosov Moscow State University, IPI RAN. vkorolev@comtv.ru
Abstract: Estimates of convergence rate in limit theorems for compound doubly stochastic Poisson processes (compound Cox
processes) are used for a more accurate description of the behavior of reliability of complex modifiable technical
and information systems within the framework of continuous-time non-homogeneous recurrent reliability variation models
Keywords: compound doubly stochastic Poisson process; compound Cox process; reliability variation model;
availability function; guaranteed confidence bounds
INFORMATION TECHNOLOGY OF USING FACIAL BIOMETRICS FOR INCREASING AFIS THROUGHPUT
- O. S. Ushmaev. IPI RAN. oushmaev@ipiran.ru
Abstract: Nowadays, multimodal biometrics is rapidly replacing tedious procedures of identification. Particularly operating
and perspective civil ID systems use multimodal approach. The formal method for designing high-speed
multibiometric technologies and systems is suggested. The effectiveness of the approach is shown by an example of
developed experimental software with service-oriented architecture.
Keywords: biometric identification; multimodal biometrics; platform independent; service-oriented architecture

Abstract: The main goal of this paper is to describe a new type of the general-purpose operating system object - the time
interval object, which allows a general-purpose operating system to act as a real-time operating system.
Keywords: operating system; real time; time interval; extension of C language; hardware interrupt controller;
multiprocessor system

its objectives, structure, and relationships are given.
Keywords: lexical and semantic resource EuroWordNet; WordNet dictionaries; thesaurus; sinset; language
relationships; OnterLingual Index ILI
