In this paper we introduce the notion of classical quasi-primary submodules that generalizes the concept of classical primary submodules. Then, we investigate decomposition and minimal decomposition into classical quasi-primary submodules. In particular, existence and uniqueness of classical quasi-primary decompositions in finitely generated modules over Noetherian rings are proved. More...

Simultaneous thermal analysis (STA) method has been applied to study decomposition reactions of AP under a flowing nitrogen atmosphere and static air. Results obtained indicate that a phase transformation occurs prior to the decomposition reaction. Decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. Addi...

in 2005, a. abdollahi and a. rejali, studied the relations betweenparadoxical decomposition and configuration for semigroups. in thepresent paper, we introduce one other concept of amenability typeon semigroups and groups which includes amenability of semigroupsand inner-amenability of groups. we have extend the previous knownresults to semigroups and groups satisfying this concept.

Based on a decomposition result by Birkhoff and von Neumann for a doubly substochastic matrix, in this paper we propose a scheduling algorithm that is capable of providing service guarantees for input-buffered crossbar switches. Our service guarantees are uniformly good for all non-uniform traffic, and thus imply 100% throughput. The off-line computational complexity to identify the scheduling ...

Developers have began to wrap desired functionalities into widgets based on Web 2.0 techniques on mobile devices. Demand for these light-weight Web applications is expected to grow rapidly in near future. Since a widgets can be recognized as a unit providing a specific service, from the perspective of choreography, this paper adapts widgets into a mobile Peer-to-Peer (P2P) environment and propo...

Integrated approaches to management support – Business Intelligence (BI) – have become widespread. The respective solutions have evolved to highly integrated, complex solutions that cannot be treated as sequences of isolated projects anymore and require central coordination and regulation. As a consequence, companies have begun to implement BI governance structures. However, these initiatives f...

Computer-Aided Design (CAD) and Geographical Information System (GIS) are being used in tandem to support a variety of decisions throughout the life cycle of civil infrastructure systems. Existing CAD and GIS platforms have been developed independently with different purposes resulting in significant differences in terms of data formats they support, terminology they utilize, semantics of conce...

This paper presents a case study in implementing a moderately complex, useful service on an active network platform. The active application is reliable multicast with congestion control; the platform comprises the Bowman Node Operating System and the Composable Active Network Elements (CANEs) Execution Environment. The importance of the work stems from the lessons it provides about the design a...

In this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. This paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (ST) decomposition. By this decomposition, every nonsingular fuzzy matrix can be represented as a product of a fuzzy symmetric matrix S and a fuzzy triangular matrix T.
