Collision and redundancy problems in RFID system have attracted more and more attention. Collision problems have been studied intensively. However, redundant reader elimination problem is studied only recent years. In this paper, we study the simulation and analysis of algorithm RRE and algorithm TRRE (two-step redundant reader elimination), which are two algorithms used to eliminate redundant reader...
The self-index is a kind of highly compressed, self-contained full-text index. It is designed for indexing plain texts in order to reduce its permanent storage, as well as to enhance searching performance. Apart from being a sequence of characters, usually the text has specific internal structure. The data record, as a basic model of structured data, is therefore employed to represent and organize...
Today, elder care demands a greater degree of versatility in healthcare. Automatic monitoring devices and sensors are under development to help senior citizens achieve greater autonomy, and, as situations arise, alert healthcare providers. In this paper, we study gait patterns based on extracted silhouettes from image sequences. Three features are investigated through two different image capture perspectives:...
This paper deals with the collaborative campaign of pair-warships, whose decision-making process is described. Considering behavior and cognition factors of decision-makers, the mathematical model of two-decision-maker decision-making process with superior-subordinate relationship is constructed subsequently. Based on this issue collaborative decision-making consistency and its measurement are defined,...
The paper aims to present a new scheme of synchronization-based topology identification for a class of weighted general complex dynamical networks with time-varying coupling delays. By combining the adaptive control method and the Razumikhin-type theorem, a new feedback technique to identify the exact topology of the dynamical networks with time-varying coupling delay has been proposed. In comparison...
In this paper, we present personalized service recommendation algorithm PSRA. Based on Web service semantics, demographic factors and users' recommendation ratings and by redefining similarity measurement, PSRA presents different succeeding service recommendation towards the same current service to meet users' personalized needs. Experiment results show that our algorithm is feasible and effective...
If there are multiple objects attached with RFID tags within the interrogation zone of a reader, and more than one tags send their identification messages to the reader simultaneously to response the query from the reader, the tag-tag collision would happen and no tag is identified by the reader. The tag-tag collision leads to retransmission of tag IDs which results in wastage of bandwidth and an...
