Using the idea of local entropy theory, we characterize sequence tuple via mean forms sensitive in both topological and measure-theoretical senses. For sense, show that for an ergodic measure-preserving system, $\mu$-sequence tuple, $\mu$-mean $\mu$-sensitive coincide, give example to ergodicity condition is necessary. a certain class minimal systems, tuple.

In this paper, we investigate the multiple attribute decision making problems with 2-tuple linguistic information. Motivated by the ideal of generalized weighted Bonferroni mean and generalized weighted geometric Bonferroni mean, we develop the 2-tuple linguistic generalized Bonferroni mean (2TLGBM) operator for aggregating the 2-tuple linguistic information and 2-tuple linguistic generalized g...

In this paper we develop a new method for 2-tuple linguistic multiple attribute decision making, namely the 2-tuple linguistic generalized ordered weighted averaging distance (2LGOWAD) operator. This operator is an extension of the OWA operator that utilizes generalized means, distance measures and uncertain information represented as 2-tuple linguistic variables. By using 2LGOWAD, it is possib...

For a d-tuple of commuting operators S := (S1,..., Sd) ? B[X]d, m N and p (0,?), we define Q(p) (S;u) 0?k?m (-1)k (m k) (???Nd0 |?| = k k!/? ||S?u||p). As natural extension the concepts (m,p)-expansive (m,p)-contractive for tuple operators, introduce study (m,?)-expansive (m,?)-contractive acting on Banach space. We say that is (resp. (m,?)- contractive d-tuple) if Q(p)m 0 u X ?) . These extend...

1 Distributed Tuple Spaces Tuple spaces have been conceived [3] and extended under the influence of databases and messaging systems. However, there is no notion of data schemes, and queries are specified by templates, that may wildcard arbitrary fields of a tuple. Therefore, indexing tuples is a highly non trivial task, which is complicated even more by the advent of field hierarchies. As a res...

The simplicity and elegance of the Linda programming model is based on its single, global, typeless tuple space. However, these virtues come at a cost. First, the tuple space can be an impediment to scalable high performance. Second, the \black box" nature of the tuple space makes it an inherently dangerous data structure, prone to many types of programming errors. Blossom is a C++ version of L...

We consider storing the pages of a wiki in a tuple space and the effects this might have on the wiki experience. In particular, wiki pages are stored in tuples with a few identifying values such as title, author, revision date, content, etc. and pages are retrieved by sending the tuple space templates, such as one that gives the title but nothing else, leaving the tuple space to resolve to a si...

Coordination of mobile applications posses a number of issues. Devices should be able to communicate with each other without being connected with each other at the same time while maintaining privacy and limited network traffic. Current tuple based approaches solve these issues partially but none of them solves all of them. We propose a novel tuple space-based approach where tuple spaces are an...

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...
