In this paper, we propose an inheritance system for knowledgebases in which IS-A relation and IS-NOT-A relation are speci ed on the domain extended by dot notation `.'. Due to the simplicity of the framework, we can obtain several computational advantages including the following: (1) IS-A relation and IS-NOT-A relation are determined in polynomial time. (2) Satis ability of a given knowledge-ba...

in recent years, many changes have been observed in buying culture of customers and developing chain stores in iran. moreover, need to be more competition in business environments made necessary the stablishment of chain stores, the creation of competitive advantage and long relations to the costumers. regular marketing is a response to stores requirement when establishing such a win-win long r...

This study examined whether German regular and irregular verb inflection is processed in continuous or categorical ways. Two visual priming experiments contrasted regular (regular stem, regular suffix) with two types of irregular participle formation (regular/irregular stem, irregular suffix). We measured reaction times (RT; Experiment 1) and event-related potentials (ERPs; Experiment 2) and ma...

A longstanding open problem in the theory of von Neumann regular rings is the question of whether every directly finite simple regular ring must be unit-regular. Recent work on this problem has been done by P. Menal, K.C . O'Meara, and the authors. To clarify some aspects of these new developments, we introduce and study the notion of almost isomorphism between finitely generated projective mod...
