17

The article gives a description of the automatic recognition of speech commands. The system consists of several modules: a digitized signal; selection of primary features of the speech signal based on linear spectral roots, search for the standard basis of dynamic programming semantic correction of the recognition sequence of characters linguistically Dictionary. The work can be used in the field of speech technologies.

TRANSFORMATION OF SINGLY-CONNECTED BAYESIAN BELIEF NETWORKS INTO ALGEBRAIC BAYESIAN NETWORKS
Tulupyev Aleksander L

21

The paper presents the key steps of the algorithm which can transform uncertain knowledge patterns bases represented as singly-connected Bayesian belief networks (i.e. structured as a poly-tree) into the bases represented as algebraic Bayesian networks. The major part of this transformation successively performs calculation of join probability tensors based on already-known conditional probability tensors that are stored in the nodes of Bayesian belief networks. The transformation process is completed when join probability tensors are re-calculated into the set of probability estimates over elements of conjuncts ideals.

DYNAMIC SYSTEMS WITH VARIABLE STRUCTURE AND DIMENSION
Aleksander N. Kirillov

23

The approach to mathematical modeling of variable structure and dimension systems is proposed. The model is described by the systems of ordinary differential equations, the number and the form of which depends on behavior of special variables. The continuous and discontinuous variation of structure is considered. The solid body system stabilization problem is adduced as the example of proposed method use.

It is shown, that the silicon nanoclusters within layers SiO2 can have the various form and structure. In cases when silicon nanoclusters are formed on silicon substrates by methods nanolithography of surfaces with the subsequent thermal oxidation or a laser irradiation of the oxidized silicon, nanoclusters usually have crystal structure. At use of other methods of formation silicon nanoclusters for reception of diamondlike structures of these clusters, the additional processing is usually required, in particular, high-temperature anneal.
