"The concept of the nested metagraph as the model of a complex object with different levels of generalization is introduced. It is shown that the nested metagraphs reflect the general system concept for description of complex objects with synergistic effect. This approach enables moving from the set-theoretic description of complex objects to their algebraic-theoretic description, thus increasing the model adequacy to real-life objects. The application of the nested metagraphs, in particular to business-intelligence and semantic search is considered. "

The paper focuses on one of possible approaches to decision support problem, which is based on multi-agent simulation modelling. Most decision support cases generally consist of a set of available alternatives definition, estimation and selection of the best one. When choosing a solution one needs to consider a large number of conflicting objectives and, thus, to estimate possible solutions on multiple criteria. Multi-agent resource conversion process model was developed on the basis of several approaches integration: simulation and situational modeling, expert and multi-agent systems, object-oriented approach. The multi-agent resource conversion process model was extended elements coalition. Apparatus of conflict modeling was extended communications. Creation and disintegration processes of coalition are starting structural and parametric changes in multi-agent resource conversion process model. Coalition multi agent model of resources conversion process was implemented in decision support system BPsim.

The main models of DNA computing are self-assembly of DNA and RDNA. Disadvantages of these models are low speed perform arithmetic operations, the high probability of errors of computing, and perform the calculation with only fixed-point numbers. In article is represented method of encoding numbers by DNA strands. Numbers can be encoded by any base initially. This method does not require to translate the number into a binary number system. Each number is encoded by digit with the DNA. As compared with known methods, the proposed method uses a shorter length of DNA strands. The proposed method can increase speed encoding of numbers, improve the accuracy of the calculations and to reduce errors in the formation of the encoded data. In article is represented also the operations to perform arithmetic operations. The use of the proposed method of encoding numbers and proposed operations over DNA allows to increase speed of computation, and perform calculations not only with fixed-point numbers and floating-point numbers.

The spectra of thermally stimulated conduction currents (TSCC) in (TmBi)3(FeGa)5O12:Ca2+ ferrite-garnet films have been investigated with the purpose to reveal electrically active centres. The samples were fabricated by liquid phase epitaxy (LPE) from melt solution on the Gd3Ga5O12substrates with the crystallographic orientation (111) with the use of Bi-containing flux (without Pb). Increasing the concentration of Ca2+ions in the films were realised by increasing the concentration of CaO in the melt solution. The obtained films contained Ca2+ ions from 0,03 f.u to 0,1 f.u. With the help of standard thermoactivation current spectroscopy the spectra of the initial samples and samples subjected to ultraviolet radiation and negative corona discharge were obtained. The characteristic parameters of electrically active defects were calculated.

"The paper proposes a method of use of the accumulated surplus of solar water heating installation, the major element of which is the solar collector for heating of greenhouses. The heat energy, which was preserved in the battery for the summer months, can be used for heating of greenhouses in the autumn and winter months. The proposed method will significantly increase the efficiency of the solar collector and reduce the term of recoupment. This development will be relevant for the individual dwelling houses, with garden plots sufficient to build greenhouses there. The use of ""Energy - Effective"" greenhouses combined with solar water heating unit, significantly reduces the cost of electricity and heating. The use of low-grade thermal energy from the sun and soil is the main direction of development of energy-saving technology of housing and communal services. "

Most of web pages of the Web are inaccessible for the blind users. And the main reason is a lack of the semantics at the source code (technical) level of web pages and absence of the navigational components. In this work we propose a new web page representation---multiaxial navigation model---representing web documents in the form convinient for the blind users. Moreover, we present methodology for the navigation on the model proposed, that ensure an efficiency of user mobility. Automatic transformation of a web page into the multiaxial navigation model and navigation means are realized in the Blindzilla prototype. An efficiency of the proposed concepts is proven experimentally regarding contemporary screen readers, such as JAWS, Window-Eyes, and Fire Vox.
