This paper presents a semantic and adaptive service for context-aware information management system for supporting ubiquitous computing applications in a smart vehicle space. In ubiquitous computing environments, systems consisting of different device types, operating systems, network interfaces, and communication protocols. These contexts change dynamically and the applications have to adapt their...
In ubiquitous computing environments, the software component model with semantic information and adaptation to satisfy various resources constraints and component interdependence is needed. This paper mainly presents an adaptive and semantic component model for an adaptive middleware. The model consists of an adaptive component model and a semantic virtual agent model. The contribution of our work...
With the increasing demands for adaptive middleware of dynamic systems in ubiquitous computing environments, the need for dynamic software architecture and programming infrastructure to achieve dynamic adaptation is widely recognized. The paper firstly presents a semantic and adaptive middleware architecture called ScudWare that supports for ubiquitous computing environments. Specially, a Scud-ADL...
Network-based computer aided assessment system has played an important role for computer education reform. In this paper, we firstly analyze the problems caused by computer aided assessment system in large-scale heterogeneous distributed environments. Then we give a short introduction of Zhejiang computer grade examination. Next, we mainly present the system of Zhejiang computer grade examination,...
As ubiquitous computing pursues naturalness and harmony, the need for context-ware ability in software middleware is growing to respond to highly dynamic computing environments. In order to facilitate the realization of such ability, the middleware infrastructure is required to acquisition, representation, fusion, and inference context information correctly and reliably. This paper is concerned with...
Compared with smart spaces addressed previously, the smart vehicle space is quite special. First, unlike room, it is a high mobile space. Second, it requires frequent information exchange with the outer environment; for instance, it may need local traffic information and other local services. The complex vehicle space needs a software infrastructure of high adaptation to meet the complex and easy...
The need for component-based middleware adaptation is growing, due to the complexities of increasing prevalence of ubiquitous computing. Software middleware must dynamically adapt to changing environments and conditions. Dynamic adaptation must be performed reliably and correctly. The focus of this paper regards an approach to formally specifying adaptation semantics for scudware middleware in smart...
