In this paper an overview of a novel run time system for the management of tuple spaces, which utilises implicit information about tuple space use in Linda programs to maximise its performance. The approach is novel compared to other tuple space implementations because they either ignore the information, or expect the programmer to provide the information explicitly. A number of experimental re...

Because of the complexity of decision-making environment, the uncertainty of fuzziness and the uncertainty of grey maybe coexist in the problems of multi-attribute group decision making. In this paper, we study the problems of multi-attribute group decision making with hybrid grey attribute data (the precise values, interval numbers and linguistic fuzzy variables coexist, and each attribute val...

This paper describes a generalisation of the binary N tuple technique originally described by Bledsoe and Browning (1). The binary N tuple technique has commonly been used for the classification (2) and pre-processing (3) of binary images. The extension to the method described here allows grey level images of objects to be classified using the N tuple method without first having to convert the ...

A tuple t1 of relation R subsumes tuple t2 of R, with respect to a query Q if for every database, tuple t1 derives all, and possibly more, answers to query Q than derived by tuple t2. Therefore, the subsumed tuple t2 can be ignored with respect to Q in the presence of tuple t1 in relation R. This property nds use in a large number of problems. For instance: during query optimization subsumed tu...
