Control models of data flows in Internet under instability
No full textThis paper deals with the control model of network data flows. We proposed an approach to analyzing network work using fluid models and conflict control theory domain. We obtained analytic solution for certain class of networks and proved time optimality. We considered special case of network activity – denial of service attack.Prombles in programming 2011; 3: 38-5
On unification of processing methods of the structured information
No full textThe problem of search and collection of information from DOM models of the same type is examined inthe article. A mechanism of collection of the structured information from relevant sources is offered, that allows to build the universal analyzers of data from these sources.Prombles in programming 2011; 4: 56-6
The Code is based on random numbers with irregular distribution
No full textThere is a proposition of a new principle of construction of cryptographic systems. This innovative principle is utilizing encryption system that based on random numbers with an uneven/irregular distribution. It has been noted, this encryption method has the highest degree of resistance to traditional cryptographic attacks, including: selection of all key variations, known original text and the specially selected original texts.Prombles in programming 2011; 4: 90-9
Current state and extention problems of the service-oriented paradigm
Full text linkBased on the analysis of the development of software engineering, the main principles and sources of the service-oriented paradigm are identified. The architectural features and basic templates of service-oriented applications and the standards on which they are based are considered. The software engineering of service oriented application development and the current state of its support tools are described. The main problems of building service-oriented applications are identified and ways to overcome them are proposed.Problems in programming 2025; 2: 3-1
Variability assurance mechanisms in Software Product Line
No full textThe main steps and problems of variability assurance process in Software Product Line (SPL) have been defined. The general model of internal structure of reusable asset has been offered which helps to distinguish base components of variability mechanisms. The set of internal and external variability mechanisms have been analyzed and it has been proposed the recommendation of their exploitation by assets’ SPL developers.Prombles in programming 2011; 1: 56-6
Integration of Semantic WEB technologies with Business Intelligence 2.0 systems
No full textThe perspectives of such Semantic Web components as metadata, ontology, semantic Web-services and intelligent software agents, are considered for intellectualization of Business Intelligence 2.0 (BI) facilities with the purpose of converting of information into knowledge, and knowledge – in business-actions for certain useful results. Today the BI software is quickly developed and widely used that is why the integration of BI with Semantic Web influences both on development of ВІ-platforms and on interest to practical applications of Semantic Web.Prombles in programming 2010; 1: 79-8
Block algorithm for Householder transformations for hybrid architecture computers
No full textA parallel block cyclic algorithm for two-sided Householder transformations for hybrid architecture computers with multi-core and graphic processors is dealt with in the paper. Results of testing are presented together with investigation of algorithm’s characteristics (scalability, acceleration) depending both on its parameters and parameters of matrix being transformed.Prombles in programming 2014; 2-3: 99-10
Matching data between electronic documents and database tables with automated SQL-query generation
No full textThe paper describes a method of automated generation of SQL-queries to making data relevant electronic documents and relational database tables for actualization the information space organization. Method which describe in this paper allows considerably to shorten the number of hand operations of creation SQL-query.Prombles in programming 2014; 2-3: 160-16
Methods of simulation of behavior of agents in multi-agent system “Navigation”
No full textThe problem of pursuit on a plane from the point of view multi-agent approach is researched. Setting up of the task of pursuit is carried out and simulation methods of behaviour of the agents, realized in multi-agent system “Navigation” are stated, which intended for modelling of processes of pursuit on the sea of the ships-infringers by the ships of a coast guard.Prombles in programming 2014; 2-3: 212-22
