Such a situation, however, is an ideal test case for service-oriented(More)
Accepting recent proposals to supporting dependable e-health enterprise systems via the adoption of emerging autonomic grid computing and services-oriented architecture (SOA); this paper presents the motivations for a novel semantics/knowledge plane for a service-oriented e-health middleware and applications. The paper starts by a detailed description of a(More)
Situated autonomic computing requires systems to possess and/or be able to access feedback and context information, from their environment, including instrumentation and sensor data. This paper presents the motivation and development details of a sensor and actuator framework, together with its associated description language, developed for widely(More)

The inquiry is an activity that is performed by the malicious object during its initiation. The malicious object uses this activity to ensure its uniqueness in memory. The inquiry can be regarded as a common behavior(More)
The next generation software applications will be required to run on globally distributed heterogeneous assemblies of disparate resources including emerging computing grids. Such applications call for seamless integration and interoperation between varieties of service standards and architectures developed and deployed using existing service middleware(More)
