Abstract: The problems of modern digital libraries (DLs) creation are addressed. General requirements on integration with external data sources and standartization are proposed among with some means to satisfy them. Leading world standards for DLs are considered. As a result of practical implementation of studies, DL management system
LibMeta is presented as an universal tool for DL creation.

Abstract: The problem of integration of heterogeneous information about color pixels, their transformation in user computer
system, standard and individual color perception of user in uniform information and communication environment
has been considered. It is necessary to solve this problem in order to create special easy-adaptable to system
components program-technical tools, providing the adequate perception by arbitrary users of output on peripheral
devices of PC. When solving the problem, the new representation methods and analysis of heterogeneous
(quantitative and qualitative) information on bounded color spaces, multicriterion choice for prediction of
difference in color information and pixels classification for structuring of color spaces are used.

MATHEMATICAL MODEL AND HUMAN POSE RECONSTRUCTION METHOD
BASED ON STEREOMATE IMAGE SILHOUETTES.
- A. Tsiskaridze Moscow Institute of Physics and Technology, AchikoTsi@gmail.com
Abstract: A problem of locally symmetric object reconstruction based on a stereomate of silhouettes when occlusion is absent
is discussed. Two models of an object are considered. In the first model, an object is described as a union of fat
spatial curves and a method of restoration of such objects is presented. In the second case, an object is described as
a joint model and a fitting method based on a stereomate of silhouettes is proposed. The methods are based on a
construction of continuous skeletons. The methods have been compared for human body pose reconstruction.
Keywords: stereore construction; skeleton; cylindrical objects; joint model; medial axes
MODELING AND CLASSIFICATION OF MULTICHANNEL REMOTELY SENSED IMAGES
- V.A. Krylov Department of Mathematical Statistics, Faculty of Computational Mathematics and Cybernetics, M. V. Lomonosov Moscow State University, firstname.lastname@example.org
Abstract: A novel approach to modeling of multichannel remotely sensed images is proposed. This approach suggests to use
the classical statistical probability distribution estimation methods for single channels and then the construction of
the joint probability distribution of amultichannel image via copulas. An integration of the developed copula-based
approach with aMarkov random field model is proposed for supervised Bayesian image classification. Experiments
with real remotely sensed images captured by a synthetic aperture radar demonstrate high accuracy classification
results proving the efficiency of the developed approach as compared to state-of-the-art methods.
Keywords: multichannel image; copula; Markov random field; Bayesian classification
COMMUNICATION BETWEEN TIME AND STRUCTURAL-TOPOLOGICAL CHARACTERISTICS

- А.A. Kuznetsov Vladimir State University, email@example.com
Abstract: According to 628 electrocardiogram registration at 177 healthy and ill people, the comparative analysis of parameters
of real and virtual heart rhythm diagrams for a regulation system influence estimation on a heart rhythm is carried
out. Between diagrams parameters and information entropy in conditions of discrete seasonal adaptation, functional
communications are determined. "Organism functional condition formulas" connecting a heart rhythm diagram
macrostructure parameters with its storey microstructures parameters are offered. It is revealed that the mode
of a healthy person heart rhythm without sex dependence has a calendar year cycle, during which it three times

Abstract: The method and tools to use Algorithmic State Machine (ASM) formalism for high-level specification of complex
digital designs and their Model-Checking-based verification are described. This methodology is based on the
possibility of hierarchical description of the target digital designs at algorithmic level of abstraction, and ability
to generate finite state machines (FSM) models of the systems from the ASM flowcharts. The software tool was
developed for automatic generation of SMV (Symbolic Modes Verifier) codes from the ASMs and corresponding
FSMs. A way of this approach application to design verification is demonstrated for a pipelined microprocessor.
Keywords: formal verification; Model Checking; finite state machines

ESTIMATES FOR CONVERGENCE RATE OF DISTRIBUTIONS OF RANDOM SUMS

Abstract: New estimates for convergence rate of distributions of random sums with infinitely divisible indices were obtained.
These estimates remain true under weaker conditions than the known ones. As an example of this result, the article
contains estimates of the accuracy of the normal approximation for the distribution functions of random sums with
indices that have negative binomial distribution.

Abstract: There are some dependences between main parameters of situational (or congress) hall. It is possible to link the
diameter of hall (the largest distance between any two points of the hall), the informativity of demonstrated on screen
content, the quantity of people working with a screen and also screen dimensions. The base for describing these
dependences are the recommendations fixed in the Russian state standards and simple geometric considerations.
