This paper considers the problem of containment of conjunctive queries CQ with disjunctive integrity constraints Query containment problem in the pres ence of integrity constraints has been studied broadly especially with functional and inclusion dependencies However to handle incomplete information in the database disjunctions are needed to be expressed as integrity constraints In this paper w...
This paper considers the problem of containment of conjunctive queries (CQ) with disjunctive integrity constraints. Query containment problem in the presence of integrity constraints has been studied broadly, especially with functional and inclusion dependencies. However, to handle incomplete information in the database, disjunctions are needed to be expressed as integrity constraints. In this ...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Recent approaches in the research on inconsistent databases have started analyzing the first-order reducibility of consistent query answering, i.e., the possibility of identifying classes of queries whose consistent answers can be obtained by a first-order (FOL) rewriting of the query, which in turn can be easily formulated in SQL and directly evaluated through any relational DBMS. So far, the ...

abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
conjunctive use of ground and surface water can increase reliability of the water supply by providing independent sources. in this study, corrected utility-efficient pro-gramming that allows for more than one seasonal irrigation depth for each crop was used to determine the amount of utility maximizing investment in the well capacity for conjunctive use. results showed that optimum investment a...
