Collaborative research activities often meet the barest necessity of deep unpredicable changes to be made on the base of the whole its history. It is usual for highly innovative projects. The problem of proper information support for such an activity has neither standard nor simple solution. Proposed system architecture and the first practical steps related to innovational educational technologies are described.

The press-release is a short message for press. Any important event which is expected to induce a reaction of mass media can't occur without it. It is originating from the development of the print media and the expansion of information field. In that times the necessity of structured presentation of the information for mass media appeared. At present, with the development of new communication environ¬ment, Internet, the press-release have gotten new possibilities for expression and spreading. Today Skype, FaceBook, ICQ, RSS became the important part of this PR instrument.

Traditional university «science oriented» method¬ology is directed to train of skilled specialists in the research fields. But the most of IT companies are in need of engineers who are fine orientated in modern technologies and are capable to create quality ap¬proaches on the basis of program and technological components. These specialists may be trained only in close partnership of university and company on the basis of special corporative university laboratories.

This article focuses on the use of interactive games in the learning process and after-hour ac¬tivities and influence of these games on the development of cognitive interests of junior schoolchil¬dren. The authors share their application experi¬ence of interactive games not only for checking the level of acquired knowledge, encouraging self-study material, but also enhancing the work with gifted children.

While modern society is developing information technologies (IT) used more and more which influ¬ences the way education is reforming. The important direction of that reforming is perfection of the content and technologies of education that is closely linked to preparation of the future specialists for usage of informational and communication technologies in professional work. The research of techniques for IT's training allows to select a number of education¬al principles for preparation of specialists in public relations.

For all automated management systems the task of data representations creation is one of the ma¬jor. In the automated management systems there is a certain class of data representations for which there are no automated creation methods meeting modern requirements. It stipulates an urgency of de¬veloping the technology for automated creation of data representations.

In this paper we solve the problem of literature texts classification on genres and authors by means of statistical methods. The main instrument of this analysis is the text distribution function by letters and also the sample distribution function. Every text under consideration has sufficiently large volumes, so that its distribution can be treated as stationary one with the accuracy about 3%. For such texts the distances between their distributions are calculated in the space of integrable functions. Classification criterion is based on the closeness between two-lateral text distributions. This method enables to determine the author with the accuracy of 5% and genre — with the accuracy of 15%. One-lateral

A problem of geometrical modeling of complex solids is the actual problem of modern applied math¬ematics, CAD and CAGD, computer graphics. A theory of R-functions allows to produce a sin¬gle real function for the functional representation of a complex object. R-function is a real function, which sign is completely defined by signs of it arguments (in general, some property of function is completely defined by same properties of arguments). The method of R-functions combines clearness of the CSG and the power of mathematical functions.

Management of ecological safety is rather actu¬al problem demanding multidisciplinary approaches and modular decisions. For the decision of problems it is offered to use technology of multi-agent systems which distinctive feature is individual and distributed approach. The multi-agent system consists of some intellectual information agents reflecting all hierarchi¬cal levels of ecological-economic system. Agents are capable to cooperate and adapt for changing of external conditions.

The distinct tendency of transition from the tradi¬tional passive systems of video surveillance, to the semi-automatic systems, drawing attention of the operator only in really necessary situations was out¬lined today. The Intellectual Video-Surveillance Sys¬tem (or Intelligent Surveillance System) term is used for such computer systems of surveillance which are carrying out the control over changes of the observ-able scene. In this article described the coprocessing method for video sequences in the space and time areas. It is intended for application as a part of surveillance systems along with other known methods of pro¬cessing and the analysis of the video data.

In this paper we consider fast matrix-driven algo¬rithm for computing the checksum on the examples: CRC8 and CRC32. This algorithm is easy to imple¬ment in combinational circuits and does not require storage device in the hardware implementation. The proposed algorithm requires less memory with its software implementation in contrast to table-driven implementation, especially in the processing of two, three or more bytes of data per cycle. A comparative analysis of the table-driven and the proposed matrix-driven algorithms is done and recommendations on the use of a matrix algorithm for computing the checksum CRC are given.

In this work the program package for optimal parametrical identification of nonlinear models is developed. The algorithm of Levenberg-Marquardt in Fletcher's updating is applied. The developed program package is applied for researching of the mathematical model describing dynamics of socially-economic system of USA. Earlier such mathematical models have been used for the analysis of socially-economic system of Russia and have shown the suf¬ficient adequacy.

In our days creating informational calculating complexes for risk assessment in human-technical and ecological systems is beginning to be a fac¬tor defining fundamental and applied research success in projecting and exploitation objects with higher level of risk, in planning of measure directed to decrease damage from catastrophe.
