Item A natural classification as a systemological method for knowledge modelling(Українські технології, 2006) Bondarenko, M.; Solovyova, K.; Matorin, S.; Elchaninov, D.The main purpose of the given work is the application of systemological classification analysis method and natural classification criteria for conceptual knowledge acquisition, ontologies and knowledge bases creation. Method based on natural classification helps to investigate deep semantic regularities of subject domain and to take proper account of system-classes essential properties the most objectively. It allows receiving the forecasting parametrical classifications and effective ontologies in different ill-structured problem domains, knowledge management, organizational modelling for companies’ sustainable development and competitive advantages providing.Item The system approach to organization of waste treatment in cities of Ukraine(Lviv Polytechnic National University, 2006) Ogorodnyk, I.; Dwulit, Z.Item Supporting the entire lifecycle: enterprise content management methodology(Українські технології, 2006) Zykov, S.The paper considers content management in web portals, which are built on heterogeneous enterprise information systems (IS). A huge data bulk is accumulated by the enterprises, and it tends to increase further.

There the advantages and disadvantages, general reasons of blended learning application instead of distance one are described and the peculiarities of their own experience are reported and demonstrated by each author.Item Mechanism sequential access of parts of decomposition on the basis of the technique of optimal circuit reduction(Українські технології, 2006) Bazylevych, R.; Hudz, I.There were considered the peculiarities of programmatic realization of mechanism sequential access of parts of decomposition of complex circuit. There were revealed main approaches of carrying out of starting optimization of sequential parts of decomposition.Item Modern concepts of realization functional safety and reliability in real-time operating systems(Українські технології, 2006) Turkin, I.; Nikitina, T.In the given research are analyzed methods of reliability and safety of Real-Time Operating Systems (RTOS). Standards of safety for RTOS and existing developments in the given direction are discussed in detail, also the concept of realization partitioning Operating System, RTOS architecture are viewed. Realization of key mechanisms of work with virtual memory, interaction of processes and threads according to POSIX are explained.Item Realization of operations with nested relations(Українські технології, 2006) Hryhorovych, A.; Hryhorovych, V.There have been reviewed object-relational peculiarities and work with nested relations in the industrial SMDB. There have been given the examples of operations with nested relations by means of Oracle, SQL3, SQL4 and XML.Item The menaces analysis of the distance education process(Українські технології, 2006) Gajsha, A.The menaces of the distance education process are analyzed, described and classified. The recommendations to build strong and safe distance learning protection system are presented. The well-known methods to neutralize the menaces of view are analyzed and also there are short descriptions and references to proper author’s works.Item Universal software system requirements classification(Українські технології, 2006) Shekhovtsov, V.; Kostanyan, A.This paper presents new requirements classification. It’s more flexible than traditional functional and nonfunctional requirements division. Classification model is based on modern faceted approach and used International Standardization Organization software quality model. Join universal model with improvements and usage examples is introduced.Item Informational-analytic system with e-learning component of educational institute management development(Українські технології, 2006) Peleschyshyn, A.; Zhezhnych, P.; Holoshchuk, R.This paper describes architecture of the complex information system with E-learning component of Institute of computer sciences and information technologies (ICSIT), National University “Lviv Politechnika”, and some approaches of the system functional improvement. Disadvantage of existing activity automation systems of other higher schools are analyzed. The structure the system components with their functionality and implementation are considered in details.Item National Ukrainian grid infrastructure (ugrid) for sciences and educations(Українські технології, 2006) Zgurovsky, М.; Petrenko, А.Development of Ukrainian national GRID infrastructure is considered. Main components of this GRID are: Ukrainian Research and Academic Network, the system of distance learning, distributed information resources in education and science, electronic libraries and the administrative and educational system “Osvita”. Gridinfrastructure provides the Ukrainian universities, research centres and virtual laboratories by the information and required computational resources. In conclusion the international collaboration of Ukraine with Europe in GRID development is considered.Item Scanning-area algorithms for clustered TSP(Українські технології, 2006) Bazylevych, R.; Dupas, R.; Kutelmakh, R.One of the base problems of combinatorial optimization, that has wide applications, is the Traveling Salesman Problem (TSP). Rapid growth of its size (thousands of points) is the main feature now, and many extensions of this problem with specific properties are studied: dynamic vehicle routing problems; systems with call (the first-aid, the courier's, the taxi), systems with time windows, and systems of delivery. They need development of the special algorithms, which provide high-quality solutions in reasonable time. That is why subsequent perfection of existing algorithms and development of new ones is relevant. In this paper, a set of strategies were proposed and evaluated, in order to solve specific TSP problems in which the points are under the form of clusters.Item Knowledge-based data analysis technology and its applications(Українські технології, 2006) Kravets, Yu.; Kravets, R.Authors consider the problem of the text documents analysis system development on the basis of knowledge-based data analysis technology and its application to the emergency situations descriptions analysis.

The solution of the processes prognosis problem in the case of the signal with partially loosed and contradictory data is proposed.Item Supporting the entire lifecycle: enterprise content management methodology(Українські технології, 2006) Zykov, S.The paper considers content management in web portals, which are built on heterogeneous enterprise information systems (IS). A huge data bulk is accumulated by the enterprises, and it tends to increase further. Global distribution of the heterogeneous data and its weak-structured character complicate its uniform management. A problem-oriented approach for enterprise content management is presented, which includes a formal model and a software development toolkit. Implementation results demonstrate significant terms and cost reduction.Item Run-time reconfigurable system for distributed algorithm execution(Українські технології, 2006) Grytsenko, A.; Malcheva, R.; Barkalov, A.Run-time reconfigurable systems (RTR systems) allow configure hardware computing resources during computation process, without it interruption.

The present article sketches the basic components of discourse processing mechanisms, such as constructing explanations, asking deep-reasoning questions, tutoring, and subsequently points out how such mechanisms can be recruited to improve deep comprehension of the study material. The practical mission is viewed as designing of software (both the programming and the linguistic parts), modeling the pointed out mechanisms, which is suggested to become a part of the student-teacher research work carried out in the field of Applied Linguistics.
