This paper presents a construction approach for software agents. A software agent is regarded as a main frame plus some components, and it is constructed by selecting suitable main frame and software components, assembling and running through the control mechanism on the main frame. The multi-agent system is organised on the Client/Server model. The… (More)
This paper proposes a domain-specific software architecture style. In the architecture style we define three software component types: procedure components, object components and agent components. We design a software bus or connector called Tribus to facilitate interactions among these components and specify one way quotation relations between different… (More)
Interoperation and services sharing are becoming new paradigms for enterprise collaboration, which brings a meaningful requirement of flexible specification and enforcement of security policies in information systems: Problem ¾ Flexible specification: specifying policy against multi elements with different criteria, like evaluating partners' qualification… (More)
Pervasive computing are nowadays in widespread use, deeply penetrating into and increasingly demonstrating its significance in our everyday work and leisure life. In the last decade, cheap and low energy consuming devices made far-reaching impact on the pervasive computing paradigm and fueled up a plethora of new applications. For instance, solar-powered… (More)
In this paper, two evaluation factors are proposed to evaluate subdivision methods based on surface moments. Both factors are derived from moment invariants, and mainly used to measure shape stabilization. The experiment results show these factors are able to measure the distortion characteristic of 3-D models.
