  • Application of Lyapunov's Direct Method to the Existence of Integral Manifolds of Impulsive Differential Equations

    Stamov, G. (1996)
    The present paper investigates the existence of integral manifolds for impulsive differential equations with variable perturbations. By means of piecewise continuous functions which are generalizations of the classical Lyapunov’s functions, sufficient conditions for the existence of integral manifolds of such equations are found.

    Types and Annotations for CIDOC CRM Properties

    Alexiev, Vladimir (2012)
    The CIDOC CRM provides an extensive ontology for describing entities and properties appearing in cultural heritage (CH) documentation, history and archeology. CRM provides some means for describing information about properties (property types, attribute assignment, and "long-cuts") and guidelines for extending the vocabulary. However, these means are far from complete, and in some cases there is little guidance how to "implement" them in RDF. In this article we outline the problems, rel...

    Maximum Principle and Its Application for the Time-Fractional Diffusion Equations

    Luchko, Yury (2011)
    MSC 2010: 26A33, 33E12, 35B45, 35B50, 35K99, 45K05 Dedicated to Professor Rudolf Gorenflo on the occasion of his 80th anniversary In the paper, maximum principle for the generalized time-fractional diffusion equations including the multi-term diffusion equation and the diffusion equation of distributed order is formulated and discussed. In these equations, the time-fractional derivative is defined in the Caputo sense. In contrast to the Riemann-Liouville fractional derivative, the Caput...

    Computer-aided System of Semantic Text Analysis of a Technical Specification

    Zaboleeva-Zotova, Alla; Orlova, Yulia (2008)
    The given work is devoted to development of the computer-aided system of semantic text analysis of a technical specification. The purpose of this work is to increase efficiency of software engineering based on automation of semantic text analysis of a technical specification. In work it is offered and investigated the model of the analysis of the text of the technical project is submitted, the attribute grammar of a technical specification, intended for formalization of limited Ru...
