The authors describe technology of represen¬tation of spatially-distributed data in the Internet. Its key element is geo-information system for display of bidimentional materials, such as plans of industrial units and communications, technological schemes, drawings of devices, etc. As a base for visualization of these materials cartographical web-service Map-server is used. For visualization of three-dimensional models of the spatially-distributed objects Web-Pub¬lishing and eDrawings are used. Attributive information necessary for visualization of plans and models of objects is displayed by means of tools created in PHP.

In Russia insurance became the main serious tool for risks control because of immaturity and un¬popularity of idea of risk-management. There is a re¬quirement for support of a steady financial and eco¬nomic substantiation of economic efficiency of used budgetary funds at liquidation of emergency situa¬tions in various locales and branches of our coun¬try, including implantation of system of risk-manage¬ment. A probability tree is the graphics or tabular ap¬proach to the organization of possible sequences of monetary streams.

For complex software systems the actual prob¬lem is User immersion into the program ideology to improve the efficiency of its use. The paper pres¬ents a methodology for describing the software product that enables the formal yet clearly describe the operation of program to User. The proposed ap¬proach shows the User his role and contribution to the final results of the program.

The load for each session node is individual. It is important and efficiently from economic point of view to choose software for protection. For this purpose created imitational model which is imitating real at¬tacks and answers from administrator and is defin¬ing the vulnerability level of system based on analy¬sis protection measures used.

Jointly considered methods of synthesizing and presenting the structure of technical systems (TS) in relational databases. As a way of presenting the structure of the TS selected N-oriented hypergraph, TS structure synthesis by using production rules. In the format presented SQL syntax rules and algo¬rithm processing. Scope — CAD / CAM systems: design of equip¬ment, design of flowsheets, placing equipment on the shopfloor.

In process of developing and testing algorithms of digital image processing there is a need to assess image quality. It's known that the best way to assess image quality is an expert approach, but it requires a large amount of people and time. The effective solution of these problems is the development and utilization of mathematical algorithms. These algorithms should give results as close as possible to the experts' results. Algorithm SSIM is one of the most reliable and has the opportunity of further improvement of results' reliability. A computer experiment was settled to solve this prob¬lem. The experimental results showed a significant in¬crease of the reliability of quality assessments.

This paper presents a method to improve MPEG video translation in TCP/IP wide area networks. Op¬posite to many proprietary applications where video quality and transmission rate depends on available bandwidth we elaborated an approach based on prioritized packet forwarding for frames being most important for successful video stream decoding. Our implementation is based on the standardized «Dif-ferentiated services architecture" with well-known AF PHB policy. This allows our approach to be implemented on common network equipment provided by leading vendors.

The federal law #83 from May 08th, 2010 pro¬motes coordination of sizes and qualities of the state services with sizes of budgetary appropriations on these purposes, and also to transition from financing of activity of budgetary establishments to financing of the rendered services. The developed technique allows to form an order and financial support of performance of the state job by federal official bodies.

In this work, using of graphology for synthesis of persons' psychological portrait is considered and using of theory of fuzzy logic for handwriting pa¬rameters find is offered. It is possible turn from get¬ting a set of personal psychological characteristics to synthesis of personal psychological portrait us¬ing handwriting parameters as fuzzy variables. This method allows to find true data and to avoid the in¬consistency in results interpretation.

The article describes analysis tools of text collec¬tions on the basis of graph-theoretic models, imple¬mented in information system «Folklore». With the help of these tools, input, storage, editing, visualiza¬tion, aggregation and comparative analysis of texts and their graph-theoretic models are realized. These methods can be used to solve the problems of genre differentiation and attribution of texts, compiling of the¬matic indexes, abstracting and information retrieval.

According to last neurophysical researches, cognizance of the education material may be con¬siderably improved, if its explanation is accompa¬nied by visual submission. Therefore development and use of various software for presentation of the educational information is an actual problem today. There are a number of practical questions concern¬ing development of such features. In this article the practical aspects of multimedia interactive presen¬tation for educational mathematical information are considered.

Decompiler is a tool for reconstructing programs from low-level representation to high-level one. The most known decompilers have correct decompila¬tion as their only goal. However, the correctness of a decompiled program is not enough for reaching higher level of program representation. We present a quality of decompilation as an additional require¬ment for decompilation. Decompiler TyDec recon¬structs low-level programs and traces correctly and with high quality.

The article delineates the system of negative consequences of «Social Web» (or «Web 2.0») im¬pact development. Though the new paradigm gives great possibilities for constructive activity, such phenomena as falling level of literacy, lowering rele¬vance of search output and confidence to the elec¬tronic information are more and more noticeable as «Web 2.0» comes into power. According to the author, there are three possible scenarios of future events most negative of which, though quite Prebable, is definitive littering of the Internet. Outputs are supported by facts and results obtained through substantial theoretic researches and overviews.
