An approach for dynamic load balancing of mobile agents is described. We demonstrate this approach for a multi-agent system operating on an active digital library composed of multi-spectral images of the Earth, as part of the Synthetic Aperture Radar Atlas (SARA)[25]. In the proposed architecture specialized stationary agents are used to gather system state(More)
A system that conforms to FIPA specifications (standards) is a FIPA-compliant system, and can interoperate with any other heterogeneous systems which are FIPA-compliant also. The conversion of a Multi-Agent System (MAS) into a FIPA-compliant system (i.e. one that adheres to FIPA standards), is important to support interoperability across different MAS. A(More)
—The key test for confidence in any association discovered within the medical domain is replication testing. That is, the ability of the association to be detected in independent populations. At the same time, in order to increase the likelihood of discovering statistically significant associations there is a clear need to increase the statistical power of(More)
An agent-based architecture of a n active Digital Library (DL) is first described, to illustrate how electronic service provision can be supported through the use of agents. The use of mobile agents is presented as a key enabler for allowing services to be combined from a variety of providers. Load balancing approaches are then used to illustrate how(More)
The conversion of a MAS into a FIPA-compliant system (i.e. one that adheres to FIPA standards), is important to support interoperability across different MAS. Supporting such a conversion will also allow system developers to make more effective use of their existing systems. Such a conversion imposes amendments on the system architecture to conform to the(More)
Digital Libraries (DLs) provide an important application area for deploying mobile agents, and with the increase in content being made available within such libraries, performance concerns are becoming significant. Current DLs often involve content servers which are geographically distributed, often necessitating information from these servers to be(More)
— Biosimulation researchers use a variety of models, tools and languages for capturing and processing different aspects of biological processes. However, current modeling methods do not capture the underlying semantics of the biosimulation models sufficiently to support building, reusing, composing and merging complex biosimulation models originating from(More)
