In this article we present an infrastructure for creating mash up visual representations of the user profile that combines data from different sources. We explored this approach in the context of Life Long Learning, where different platforms or services are often used to support the learning process. The system is highly configurable and adaptive: data sources, data aggregations, and visualizations...
Major recommendation systems don't consider the user's current composite state in time. And also they do not consider the affect on the recommendation results when the user updates the context. In the process of analyzing the user's interests and preferences, it is not enough to determine the user state only based on the browsing records about the user, so more context information from the user's...
Current automatic diagnosis techniques are predominantly of a statistical nature and, despite typical defect densities, do not explicitly consider multiple faults, as also demonstrated by the popularity of the single-fault Siemens set. We present a logic reasoning approach, called Zoltar-M(ultiple fault), that yields multiple-fault diagnoses, ranked in order of their probability. Although application...
Petri nets and related models have been used for specification, analysis, and synthesis of programs. The paper contains a survey of several literature approaches and an examination of their relationship to Petri net modeling and supervisory control. The discussion is restricted to Petri net models in the class of place/transitions nets and the supervisory control of this class of models.
Service level agreements (SLAs) is currently one of the major research topics in grid computing. Among many system components for the supporting of SLA-aware Grid- based workflow, the SLA mapping module receives important positions. Optimizing execution time is an important task of the mapping module as it helps in finding out a feasible solution when the Grid is busy or by eliminating the negative...
This paper presents an initiative model for building Open Smart Space (OpenSS) environment. OpenSS is the middle stage of Smart Space identified as the test-bed for pervasive computing research. The model is regarded as a three-layered model: (1) physical space layer, introducing an ontology-based model to represent the entities, the boundary and the fusion of physical space and cyber space; (2) agent...
