A novel joint angle and delay estimation (JADE) algorithm for multipath signals, based on the PARAllel profiles with LINear Dependencies (PARALIND) model, is proposed. Capitalizing on the structure property of Vandermonde matrices, PARALIND model is proved to be unique. Angle and delay of multiple rays of sources can be estimated by PARALIND decomposition and an ESPRIT-like shift-invariance tec...

This paper copes with the problem of integrating peer-to-peer and multi-agent systems for the realization of both large-scale multi-agent systems and sophisticated peer-to-peer applications. In particular, it presents how JADE, one of the best known and most used software framework for the development of multi-agent systems, has been extended with a peer-to-peer technology, and how a JADE multi...

Due to the diversity of resources and different personalized management requirements, Cloud management is faced with great challenges in complexity and difficulty. For constructing a management system to satisfy a specific requirement, a redevelopment solution based on existing system is usually more practicable than developing the system from scratch. However, the difficulty and workload of re...

Virtual Environments (VE) present a complex problem with interesting non-trivial challenges for software development. The problems increase when considering VE that are both distributed and shared amongst multiple participants. The majority of existing systems supporting Large Scale VE (LSVE) are based on monolithic architectures, making maintenance and software reuse difficult at best. This pa...

The workflow process is often executed in a dynamic environment. This dynamic is classified in several aspects. For this reason, several researches try to give workflow architectures more adaptability in order to provide his business process more stability. This paper presented an architecture based agent to take in charge adaptability in workflow environment. The system proposed has the possib...
