  • A possible approach to the representation of the domain structure in automatic abstracting

    The problem of representation of the structure of the domain, which could be used in automatic summarization is described in this paper. As a solution to this problem, the authors propose to use a denotat-based text analysis technique , developed by A.I. Novikov and his school (Institute of Linguistics). This technique was the basis of the proposed infological model that makes it possible to view the structure of a particular subject area, and ultimately the creation of a system of automatic summarization.

  • Experimental Study of Denotative Model of Understanding in Applications of Automated Abstracting Systems

    The article deals with an experimental study of computer representation of the structure of the domain, which can be used in the automatic summarization. As a theoretical basis for the study psycholinguistic theory of AI Novikov was selected. The denotative text analysis technique which allows to explicate text's meaning in a graph structure was tested. The use of this technique allowed the authors to create a computational model for the automatic construction of graphs that reflect the contents of the natural text.

  • The usage of the parametric methods of statistics in the oil field equipment diagnostics

    The methods of the diagnostics and oil-and-gas installations state analysis reliability increasing based on usage of the parametric methods of statistics are discussed in this paper. The variance analysis of the mechanical properties of the pump rods made of normalized steel is given in this paper (according to the data of the manufacturing plant for the period of 10 years). It is found that breaking point and yield stress are distributed with the truncated normal laws in the region of minimum values. The obtained average values and variation coefficients of the mechanical properties within the steel grade permit to calculate the statistically significant changes of the mechanical characteristics. The correlations between Vickers hardness and breaking point (Vickers hardness and yield stress) in the case of steels produced in the Russian Federation for the pressure-operated vessels are also presented in this paper. These correlations permit to determine the strength characteristics with the relative error of 12% according to the hardness value. In the case of transferring the obtained correlations on the steels produced in Japan the systematic underestimation of the yield stress is 0,85 fold with respect to the value given in the certificate. The factors that influence on the microanalysis sensitivity and accuracy are revealed, the optimal scanning electron microscope mode and research conditions for the chosen patterns are also determined. Evaluation of the systematic inaccuracy of determining the carbon content in the steel is obtained in this paper. It is found that the measurement error for the scan area from 3 x 3 to 20 x 20 mm and accelerating voltage from 10 to 15 kv is minimal. The usage of the obtained results permits to increase the validity of the findings in the diagnosed installations condition evaluation and determining the conditions of their further exploitation.

  • Investigation of stress-strain state of reinforced concrete arch with a view of viscoelasticity on the basis of different theories of creep

    We investigated the creep of concrete arches based on the following theories: the theory of linear creep by Harutyunyan-Maslov, kinetic theory, the theory of flow, theory of aging, and nonlinear theory of Y. Gurieva. We considered viscoelastic model of the concrete, ie total strain was represented as the sum of elastic strain and creep strain. Solution of the problem was carried out by finite element method. We considered the arch rigidly clamped at the ends and loaded with a uniformly distributed load. Graphs of growth of deflection and stress distribution in the reinforcement and concrete are represented. We obtained the substantial redistribution of stress between the reinforcement and the concrete during creep: in reinforcement stresses increased and in concrete stresses decreased. The strongest redistribution occurs on the theory Y. Gureva.
