The current state of methods of the solution of boundary problems of mechanics of continuous environments is characterized. It is noted that packages of applied programs applied in engineering practice are based on the methods leading to solutions of boundary problems in the form of massifs of numbers. As a shortcoming the im-possibility of a reliable assessment of an error of such decisions for the majority of complex engineering chal-lenges is noted. As the alternative is stated an essence of a fictitious canonic regions method. It is shown that its application leads to solutions of boundary problems not in the form of massifs of numbers, but in the form of the functions which are identically satisfying with to the differential equations of boundary problems. The main ad-vantage of the fictitious canonic regions method - high precision of received results and possibility of a reliable assessment of their error. The review of stages of development of the fictitious canonic regions method is executed. The review of the works devoted to its application for the solution of scientific and engineering problems is executed.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
