Existing empirical research on the business value of Service-Oriented Architectures (SOA) has only measured the extent of SOA adoption – but not maturity – to determine whether typical goals, like increased business agility or IT cost reduction, could be achieved. However, a widely implemented SOA might be less mature than an SOA adopted only in particular areas of the organization, which in tu...

Block-oriented signal processing techniques have exceptional role due to the availability of fast algorithms. However , if larger data segments are to be evaluated in real-time, the delay caused by the block-oriented approach is not always tolerable especially if the response time of our evaluating system is also specied. This can be exceptionally critical if the signal processing is related to...

Distributed stream filtering is a mechanism for implementing a new class of real-time applications with distributed processing requirements. These applications require scalable architectures to support the efficient processing and multiplexing of large volumes of continuously generated data. This paper provides an overview of a stream-oriented model for database query processing and presents a ...

The wealth of information generated by users interacting with the network and its applications is often underutilized due to complications in accessing heterogeneous and dynamic data and in retrieving relevant information from sources having possibly unknown formats and structures. Processing complex requests on such information sources is, thus, costly, though not guaranteeing user satisfactio...
