The paper presents the framework for agent-enabled dynamic web service composition. The core of the methodology is the new understanding of a web service as an agent capability having proper ontological description. It is demonstrated how diverse web services may be composed and mediated by dynamic coalitions of software agents collaboratively performing tasks for service requestors. Middle Age...

in this paper some new applications of empirical mode decomposition (emd) and hilbert spectrum in seismic ground-roll attenuation, random noise attenuation and spectral decomposition are introduced. hilbert spectrum is a time-frequency representation for hilbert-huang transform which is obtained by combination of instantaneous frequency (if) concept and intrinsic mode function of empirical mode...

The aerospace alloy Ti-6246 was subjected to inductive heat treatments with high heating and quenching rates (up 1500 K/s) while being applied an in situ diffraction study at the HEMS beamline P07B DESY. Thereby, characterization of emerging phases possible any point process. treatment schedules include preparation samples by means a homogenization subsequent trigger α″-martensite formation. In...

at many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. in such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. in this research work a new a...

There is a shortcoming in reversible data-hiding algorithm in encrypted images, it is the low capacity. we put forward a new algorithm oriented security application in cloud computing, in the new algorithm of reversible data-hiding algorithm in encrypted image, we bring in cloud computing service and singular value decomposition based on matrix. Using the powerful computing and storage capacity...

Peer-to-Peer (P2P) Live streaming has become a popular service in the Internet. Recently, what is the upper bound of the streaming rate in a P2P live system becomes an attractive topic. In this report, we investigate the streaming capacity problem in both tree-based and mesh-based P2P live systems. In tree-based P2P live systems, the formulation of the streaming capacity problem has been report...

The Semantic Web facilitates integrating partial knowledge and finding evidence for hypothesis from web knowledge sources. However, the appropriate level of granularity for tracking provenance of RDF graph remains in debate. RDF document is too coarse since it could contain irrelevant information. RDF triple will fail when two triples share the same blank node. Therefore, this paper investigate...

Feature-wise decomposition is an important approach to building configurable software systems. Although there has been research on the usefulness of particular tools for feature-wise decomposition, there are not many informative comparisons on the relative effectiveness of different tools. In this paper, we compare AspectJ and Jiazzi, which are two different systems for decomposing Java program...

We formulate a two-stage stochastic integer program to determine an optimal schedule for jobs requiring multiple classes of resources under uncertain processing times, due dates, resource consumption and availabilities. We allow temporary resource capacity expansion for a penalty. Potential applications of this model include team scheduling problems that arise in service industries such as engi...
