We view match as an operator that takes two graph-like structures (e.g., XML schemas) and produces a mapping between the nodes of these graphs that correspond semantically to each other. Semantic schema matching is based on the two ideas: (i) we discover mappings by computing semantic relations (e.g., equivalence, more general); (ii) we determine semantic relations by analyzing the meaning (con...

In the present article, a numerical method is proposed for the numerical solution of the KdV equation by using a new approach by combining cubic B-spline functions. In this paper we convert the KdV equation to system of two equations. The method is shown to be unconditionally stable using von-Neumann technique. To test accuracy the error norms L2, L∞ are computed. Three invariants of motion are...

this study concerns with a trust-region-based method for solving unconstrained optimization problems. the approach takes the advantages of the compact limited memory bfgs updating formula together with an appropriate adaptive radius strategy. in our approach, the adaptive technique leads us to decrease the number of subproblems solving, while utilizing the structure of limited memory quasi-newt...

Background and aims The aim for this study was to assess the construct validity and reliability of the Health Dialogue Questionnaire (HDQ©) for eleventh grade in school through comparison of the HDQ© with Paediatric Quality Of Life Inventory (PedsQL™), Local monitoring of youth policy questionnaire (LUPP®), Health behaviour in Swedish school-aged children (HBSC©), Equal health (EH©) and The Swe...

We experimentally explore the effects and interactions of three variables considered important when bargaining over a jointly produced surplus: performance information, production uncertainties when translating performance into output, and subjective entitlements derived from the production process. We find that without performance information subjective entitlements are mostly mutually consist...

Purpose: We propose in this paper to analyze what are the factors that influence knowledge transfer both intra and intergenerational in family firms. The main objective is to establish a framework that can be used later in empirical research, although we maintain a completely theoretical approach in this paper Design/methodology/approach: This study, which is a comprehensive framework character...

A functional approach for the study of the random walks in random sceneries (RWRS) is proposed. Under fairly general assumptions on the random walk and on the random scenery, functional limit theorems are proved. The method allows to study separately the convergence of the walk and of the scenery: on the one hand, a general criterion for the convergence of the local time of the walk is provided...
