Large-scale distributed system, such as educational system, are difficult to develop due to their complex and decentralized nature. service oriented architecture (SOA) is a new form of distributed software architecture. The service oriented architecture facilitates the development of such systems by supporting modular design, application integration and(More)
With a high computational complexity of Eigenvector/Eigenvalue calculation, especially with a large database, of a traditional face recognition system, PCA, this paper proposes an alternative approach to utilize a fixed point algorithm for EVD stage optimization. We also proposed the optimization to reduce the complexity during the high computation stage,(More)
This study introduces a distributed e-education services system based on the service oriented architecture. Next generation educational services must identify and support dynamic semantic mappings to support semantic interoperability. The Service Oriented Architecture facilitates the development of such systems by supporting modular design, application(More)
