The muitiformity of device （or peer ） services and network types in such environment is apt to result in notable service isomorphs. And moreover, as the environment cannot assure the stability of network communication and device services, the situation gets worse. Therefore, it becomes urgent to simplify user operations and let them take full and highly efficient advantage of the environments. Super-Service-Odented Architecture （SSOA） is an Serrice-Otiented Architecture （SOA）-based architecture for service management and organization in peryasive environments. With combining one kind of isomorphic services into a super service, SSOA provides better scalability and quick, convenient service invocations. Also, the complexity and instability of services, and network types are transparent, and system performance is highly promoted under the architecture.展开更多

We compute the Nakayama automorphism of A-q,A n（K）, give a necessary and sufficient condition for A-q,A n（K） to be Calabi-Yau, and prove that A-q,A n（K） is cancellative. We study the automorphisms and isomorphism problem for A-q,A n（K） and .A-q,A n（K[t]）. Similar results are established for the Maltsiniotis multiparam- eter quantized Weyl algebraA-q,A n（K） and its polynomial extension. We prove a quantum analogue of the Dixmier conjecture for a simple localization （A-q,A n（K））z and determine its automorphism group.展开更多
