This paper presents investigation of nonlinear Boolean transformations inverse for which are ambiguous and

its application in cryptographical algorithms. A new method for designing such class of Boolean trans-formations is suggested. The method deals with the procedure form representation of Boolean transformations. It allowed to buil Boolean transformatiom from hundreds Boolean variables. Boolean transformation on such class can be use for accelerate of user identification based on “zero-knoledge” conseption. The relationship between transformation building time and procedure form parameters is established.

. The paper is dedicated to solving the efficiency increasing problem for data transmission error detection in

spectrum modulation channel by properties such errors appearance accounted. For the guaranteed errors detec-tion in one and more channel symbols the approach based on Chinese Reminder Theorem has been proposed. In the course of the theoretical researches of proposed approach the guaranteed error detection has been proved for errors quantity less or equal to number of the check symbols in modular representation.

The traditional analysis of program language operators if with laying out of them on separate lexemes as equal

in rights units of language complicates enough the syntactic analysis. The natural languages of intercourse are had at their perception of separation to the subject, to the predicate and other parts of language for the awareness of sense of suggestion. Something similar is offered on the stage of lexical analysis of program language operators. All lexemes are here divided into three groups: lexemes-objects, lexemes of action at al. A feature as programming if consists in the obligatory presence of pair of lexemes: lexeme-object and lexeme of action. Thus from this pair all operators begin and in this pair it is always the lexeme of action is a mandatory member. Therefore, if a lexeme-object appear at the lexical analysis, the simultaneous search of the proper lexeme of action is appropriate. Such approach allows considerably simplify the syntactic analysis of operators of language and accelelerate his imple-mentation.

In article the new hash-searching organization such that keys may storing in one of dual hash-address has been

proposed. It is allowed to limit the searching time by dual memory access. The procedure of recursion recording keys into the hash-memory has been developed. The analytical evaluation of collision probability has been obtained. The possibilities of proposed organization for hash-searching in static and dynamic arrays of data has been analyzed

The approach to the complex task decision for analytical support of software analysis and synthesis is

considered. Key elements of such approach use representation formats for specification headers contents of task decision resources (TDR) and knowledge base for analogues search, a choice of best components, use of transformation rules and decomposition mechanisms for TDR. It is shown, that application of such knowledge bases allows using the most of the previous software, and making values of target semantic variables extremely close to restriction requirements and criteria of processing speed.

The report deals with questions of computing experiment in distributed discrete-event simulation systems

OpenGPSS and GPSS/PC, their high-quality and quantitative job performances are compared. The problems of experiment distribution by independent part, deployment this part on cluster node, parallel execution and result assembles and here does not influence on the rightness of end-point also were laboured in the report.

. In the given work the approach to clustering of documents collections with unknown quantity of clusters is

described. A method of finding matrix of similarity is improved. The method is based on the statistics of key terms occurrence in documents. For quality analysis and finding of limiting values of algorithm, there was used a function of competitive similarity improving. The approach is realized as the application server SmartBase’s application. Implementation details and results of the process are shown. Russian text set is used.

. . The class of scales of notation should be defined by the order of symbol’s calculation. In A class scales of

notation, to which positional scales of notation referred to, the order of symbol’s calculation is dependent and successive. In scales of notation of B class, to which scales of notation of vestigial classes referred to, the order of symbol’s calculation is parallel and dependent. The classification of scale of notation is given.

method of designing pipelined datapaths which are configured in FPGA is proposed. The method

provides the hardware minimization due to the wide utilization of the shift register components. The method is proven at the example of the zigzag scan reordering buffer design.

The realization scheme of the informational technology for planning and management in systems with the

network imagination of technological processes and the limited resources (NITPLR) is given. On the basis of the scheme the complexes of sequential interconnected mathematical models which are compatible with the hierarchy of decisions that made on every planning level, and the systems of new highly effective intercon-nected algorithms for the planning tasks solution in current conditions were created. This has let in the first time to solve the task of planning by different optimality criteria in complex.

The subject of the article is an application of the method of prediction with certainty coefficient to a task of

developement of FOREX market mechanical trading system. An example of usage of certainty coefficient is demonstrated and formal procedure for definition of its relevance scale is provided. Quantitative results of effec-tiveness of certainty coefficient usage are provided with regard to prediction of the currency pair trend.

This article is dedicated to the problems of increasing of efficiency of fault search and elimination in IT-

systems. Methods of threshold values determination for the three-threshold scheme are proposed and analyzed. Method of fault localization in IT-systems that incorporates passive symptom gathering and active probing is proposed. Fault management system which uses these methods was developed.

, A way to improve the effectiveness of the GRID systems is proposed. The analysis of changes in channel

bandwidth capacity based on the combined trees information delivery of LSP tunnels MPLS networks is adopted. It has been shown that load distribution of the DR as well as balancing bandwidth capacity of multicast information delivery depends not only on the physical but also on the logical organization of a distributed sys-tem

. Virtualization is a key technology which helps to unite applications on various platforms and hardware of the

previous generations with use of smaller number of modern, more powerful servers with low energy consumption. Now, the opportunities offered by this technology can be essentially expanded by its using for satisfaction of re-quirements of a multilevel data storage (storage virtualization), and also for so-called client place virtualization which provides to the user access to working materials from any terminal, including territorially remote. In the article it is considered virtualization of all levels of IT infrastructure: servers, systems of storage, workplaces of a client, an infrastructure of a data processing centre.

In article the approaches for optimization of results of three-dimension scanning processing has been proposed.

Those approaches are based on procedure of processing of sets of three-dimension points to different forms of object representations. Proposed approaches has been realizing on system for computer designing in mechanical engineering.

Educatory and learning processes were studied in psychological aspect in the article, which gives a possibility to

make a mathematical model. Analysis of methods and models of statistics educational theory was also made, as well as theory of stochastic processes, which are used during processing of results of control and education plan-ning, was studied.

. Case and distributing of traffic frames are built in the networks of standard of IEEE 802.11. The parameters of

models fully answer parameters works real of network. A management is modeled a traffic in the network stan-dards of WI-FI. The comparative analysis of algorithms of management turns is conducted from the point of view a management and distributing of traffic.
