Оценка технико-экономической целесообразности использования изобретений в сложных технических системах
Known expert methods in terms of possibility of systemic evaluation of technical and economic significance of inventions have been analyzed. The approach to assessing and evaluating feasibility for using inventions in complex technical systems has been proposed. There have been given descriptions and examples of application of the approach based on the method of analytic hierarchy process and representation of technical system in the form of a graph of hierarchical relations of technical and economic parameters of structural components with parameters of system as a whole have been given. The proposed approach allows to determine the effect of elements that implement new technical solutions on integral characteristics of modernized systems, thereby significantly improving the quality of evaluation of inventions.
Main principles are formulated of the analysis of technical structure of the corporate network, grounded on the preliminary analysis of informational structure. Problems are solved of the description of hierarchical structure of network and calculation of characteristics including: load on data links, communication equipment, servers and network workstations.
Dependence of the integral evaluation of the human-machine system quality from the parameters of the operator labor organization is modeled based on a simulation model. The simulation model describes employee activities in the form of sequences of work and rest intervals. It is obtained the family of dependencies curves of private quality indicators and integrated assessment of the human-machine system quality from the number of rest intervals at different values of the initial work activity, the intensities of fatigue and recovery of operator.
The article presents the results of the task of algorithmization political model «Power - civil society» with the use of the apparatus of the theory of Markov processes and equations Foker-Planck - Kolmogorov. The solution of this problem is based on the use of analogies drawn from the study of natural and other objects, in order to mathematical modeling of the mechanisms of redistribution of power, the flow of power, «the law of conservation of power» and a number of other important concepts in political science, operating mainly descriptive and phenomenological models for understanding and understanding of the nature, complexity, and the dimension of the investigated processes
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
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.
