Search for pair production of heavy objects in 4-jets events with the DELPHI detector at LEP
Abstract
The integration between heterogeneous components is an active field of research for the conceptual database modelling community. The spatial representation systems manage data having a great level of heterogeneity. Indeed, with representation are associated alphanumerical attributes. The use of both components at the same time is not easy. We present a generalization technique defined by a semantics selection process. The generalization is applied to composite and non simply connected representations. By this way, we define a middle space for selection.
