In order to meet the design requirements of quick configuration of products for consumers, facing the problems of the poor share and reuse of product configuration knowledge, and inefficient configuration, propose the product configuration design method of product family model based on the forecast of user demands. Build the ontology modeling of product family using the share and reuse of ontol...

abstract this study investigates casual relationship between co2 emission and gross domestic product per capita in five different country groups, using cross- country data for the period 1960-2007. to achieve the purpose, the co- integration test and error correction models are applied. results confirm casual relationships between the two variables. a unilateral relationship between gdp and co2...

in this paper, the linearly conforming enriched radial basis point interpolation method is implemented for the elasto-plastic analysis of discontinuous medium. the linear conformability of the method is satisfied by the application of stabilized nodal integration and the enrichment of radial basis functions is achieved by the addition of linear polynomial terms. to implement the method for the ...
