Formalization of the Expert Knowledge for Incident's Management of Information System Based on the Ontological Approach

This article is devoted to a solution of the problem of collecting and formalization of the expert knowledge representing incidents received during the operation of information systems and designed to address the problem of increasing the efficiency of their management. The existing approaches and tools of a solution of the problem of incident management, their main shortcomings are defined. As perspective approach use of ontology subject domain providing basis for formation of conceptual model of subject domain for incident's management of information system is offered; the organization of objects of subject domain is carried out with use of classification of incidents for information systems with use of structural approach and the qualifier based on the OSI/ISO model. The article also outlines the basic principles of developing a prototype incident management system by using Thinkmap SDK tools.
Keywords: information system, control, process approach, the incident, ontology, classification, the domain model, knowledge base, the expert knowledge

Formalization of Expert Knowledge about the Usability of Web Pages Based on User Criteria Aggregation

The Choquet integral with respect to fuzzy measure is a generalization of weighted arithmetic mean aggregation operator. Due to its flexibility in the aggregation of information and because of the ability to take into account the possible uncertainties in the data has become popular in the applications of multi-criteria decision making. In this paper we consider its use in the formalization of expert knowledge about the convenience of Web pages. A solution of the fuzzy measure identification problem to aggregate user-defined criteria is disscused. The evaluation examples for the nine main criteria and the evaluation of world's leading university's Web pages is considered.
Keywords: usability, aggregation operator, fuzzy measure, Choquet integral

Thematic Classification Using Expert Model for Major Conference Abstracts

This paper is devoted to the thematic verification of the areas, streams and sessions of a major conference. An abstract collection and its expert thematic model are considered. The terminological dictionary of the conference is constructed. A similarity function between two abstracts is proposed. A non-metric clustering algorithm is used to construct the hierarchical thematic model of the conference. The expert model is considered in this algorithm and its parameters are optimized, to make the algorithmic model similar to the expert model. The expert model is compared with algorithmic model. The algorithm is illustrated by clustering of the EURO 2013 abstracts.
Keywords: document collection, thematic model, hierarchical model, clustering

High-Performance Extensions of Microprocessor Architecture for Speeding-Up of Scientific and Engineering Calculations

Computer simulation of multiscale burning and detonation processes requires an exaflop-scale performance supercomputer. The paper describes state-of-the-art approach for burning process simulation, architectures of high-performance DSP extensions from Intel and SRISA RAS. Also a number of solutions for dataflow co-processor development based on self-synchronous circuits is proposed.
Keywords: exa-scale computing, burning task, microprocessors architecture extensions, dataflow co-processor, self-synchronous circuits

The Features of Quasi Cellular Nets in Simulations of Flow-Based Systems and Their Design with Structure Approach

There is problems of design and development tools based on quasi cellular nets. Quasi cellular nets is new type of dynamical discrete structures without signature. It may be used for design and simulation flow systems. There was develop model based on IDEF0. There is organization models of quasi cellular network based processes modeling for different subjects. There is also samples of quasi cellular nets implementations in models flows of visitors on public objects especially stadium.

Problem of Peak Current Analysis at the Logic Level of VLSI Design and its Modern Solutions

Key problems of very large scale integrated circuits (VLSI) design for which peak current estimation is required and known approaches to their solution are analyzed. Advantages and disadvantages of different methods of peak current analysis are considered. Methods of peak current estimation for CMOS circuits at the logic simulation level which provide improved accuracy compared with the known methods are developed.

Situational Modeling in Geoinformatics

This article describes the situational modeling in geoinformatics. His appearance was made possible by the accumulation of experience in the field of modeling and due to increased power of computing resources. Situational modeling due to the complexity of the modeling process. It includes the separate modeling: situations, object modeling and simulation relations between the subject and situation. Situational modeling allows the analysis of complex situations and solve problems that conventional simulation does not solve.
Keywords: geoinformatics, geoinformation technology, geoinformational modeling, situational modeling, spatial information, information model
