Graph Pattern Matching (GPM) plays a significant role in many real applications, where given a graph pattern Q and a data graph G, computing the set M(Q, G) of matching subgraphs of Q in G. However, many applications like the experts recommendation in social networks, often need to find Top-K matches of a designated node v0, rather than the entire set M(Q, G). Moreover, the existing GPM method for...
Schema Matching (SM) and Record Matching (RM) are two necessary steps in integrating multiple relational tables of different schemas, where SM unifies the schemas and RM detects records referring to the same real-world entity. The two processes have been thoroughly studied separately, but few attention has been paid to the interaction of SM and RM. In this work, we find that, even alternating them...
This paper presents a robust fuzzy logic-base control scheme for a nonlinear magnetic bearing system with computing time delay. A proper Takagi-Sugeno fuzzy model is chosen to represent the nonlinear magnetic bearing. A fuzzy-model-based PDC controller is design in terms of a proposed delay-dependent stabilization criterion which guarantees the asymptotic stability of the fuzzy model. Simulation show...
To effectively evaluate thermal behavior and inter-core communication on multi-core processors, we propose a simulation methodology and the corresponding implementation with runtime power and temperature calculation in this paper. The multi-core simulator is extended from our previous work, i.e. a heteromerous dual-core simulator. In our updated simulator, the well-established power model Wattch and...
