Modern trends in the transformation of business structures and forms of inter-firm cooperation have led to the emergence of new organizational and structural solutions allowing businesses to successfully compete in the market, respond quickly to changes in the external environment and internal changes, contributing to the development potential of the business. So in the Russian economic practice, along with established corporate organizational structures and network business structures brand new specific structural forms are gaining popularity, being diversified entrepreneurial business systems, combining features of corporate and network structures, but also having specific characteristics that allow them to be identified as an independent type of structures. This paper discusses the most important parameters influencing the development of a diversified network of entrepreneurial business systems and analyses key characteristics of the data structures to identify their place in the chain of organizational structures evolution

Its properties, for example stability in wide interval of temperatures, are of great practical interest (electrodes for fuel elements, electronic apparatuses  and others).                                                                             In this article the results of studies of thermostability of sodium and potassium tungsten and molybdenum bronzes in atmosphere and vacuum condition at the temperatures range 20-1110°C were found. The samples are prepared by electrolysis of melts of sodium and potassium isopolytungstates and molybdates. Dates for bronzes Na0.92WO3 , Na0.68WO3 , Na0.53WO3 , Na0.15MoO3, K0.3MoO3 were characterized by the termogravimetric-differential- thermal analysis (TG-DTA). Regions of stability of Na0.92WO3 : 20-700°C , of MxMoO3 : 300-500°C were founded. Conclusion about correlation of  nonstoichiometry of chemical composition of EOx bronzes and oxides, which making important role in formation of less - common metal bronzes structure.

"This review covers various methods of synthesis LaMnO3 ferroics. The general analysis of the solid-phase synthesis reactions methods and wet methods (sol-gel, sorption, co-precipitation) are carred out. The original results of LaMnO3 syntheses from various precursors by means of the in situ method are showned. The advantages and disadvantages of different methods of synthesis are determined. The analysis of synthesis LaMnO3 ferroics published data is shown:
- the structure formation of LaMnO3 in perovskite-type phases occurs at different temperatures, depending on precursors states;
- LaMnO3 perovskite phases differ in symmetry and unit cells parameters at room temperature, depending on the preparation conditions;
- the highest synthesis temperature of LaMnO3 are typical for solid phase reactions method (950-1050 ° C), the lowest - for wet synthesis methods (500-700 ° C);
 - the synthesis conditions effect the stoichiometry of LaMnO3 for oxygen content.
Our studies of structure formation processes of LaMnO3 by in situ method are allowed to define the role of precursors states at synthesis of solid phase reactions methods, adsorption, co-precipitation and sol-gel mixtures.
It is determined that in samples prepared by wet chemical methods, the formation processes of  LaMnO3 perovskite phases occur at lower temperatures than by solid phase reaction (sol-gel precursor - 500 <T <600 ° C; precursors obtained by coprecipitation and sorption methods - at 600 <T <700 ° C and 700 <T <800 ° C, respectively).

There has been carried out the comparative analysis of the training algorithms of artificial neural networks of perceptron type: genetic, adaptive and hybrid.The comparison revealed that the adaptive algorithm is better coped with the task than the other algorithms. It is better to use the hybrid algorithm to solve the problem with complex target multiextremal function for which the adaptive algorithm is less convenient.

  The work in the Internet is impossible without the use of search systems. The quality of the responses to user’s requests to a large extent depends on the keywords. However, due to some circumstances the user is not able to accurately enough to formulate a request and the number of received responses is great. In these situations, additional feature relevant answers selection can be text documents belonging to a particular implicit group. Implicitness group is shown in the fact that the text belongs to it is determined not by direct comparison with the reference (key) words, but by matching the semantic features, the wording of which is absent in the search text. Implementation of text classification can be made on the basis of the frequency characteristics of N-grams. The purpose of the work is to assess the possibility of using the frequency characteristics of N-gram of the websites text fragments to improve search engine based on a study of their information content. In this work designed a method based on the selection of informative indicators of N-gram with low computational requirements and with application of the correlation analysis. Based on its application has been shown that the frequency characteristics of N-grams have sufficient information content to improve search engines. The developed method has many common with systems of writing, because it relies not only on the alphabetic systems.
