But an n-dimensional hypercube has 2n nodes, which limits scalability of networks when the degree of nodes is invariable. The paper puts forward a scalable hypercube based on the Combination Gray Code with Johnson Code (GJCode (s, t)). The GJCode (s, t) has good scalable characteristics and the important properties of both Gray Code and Johnson Code. In the GJCode (s, t), there are two adjustable parameters which offer a good tradeoff between the cost of networks and their performance in terms of the demand of application systems. The paper discusses the performance of several variations of the hypercube and proposes the routing algorithm for the GJCode (s, t), which can make packets pass along the shortest distance path and is simple in hard implementation. The GJCode (s, t) can be applied in parallel computer systems and networks on chip.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"49 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132791443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance the adaptability, the system learns direction relations between target and its shadow, automatically.

One of the most important mining tasks is clustering. There already lots of clustering algorithms for data stream have been presented. Fuzzy cluster is an important clustering method. However, to the best of our knowledge, all the clustering algorithms are hard clustering methods, fuzzy clustering algorithm is presently not used directly for data streams. Fuzzy c-means (FCM) is a typical fuzzy clustering algorithm. In this paper, we extend FCM and propose a weighted fuzzy algorithm for clustering data stream. Experimental results on both synthetic and real data sets show its superiority over the traditional FCM algorithms.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116623517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Topology aggregation is introduced for the state information reduction of domains, but it also brings distortion of the original state information. The tradeoff between information reduction and distortion is the key to topology aggregation. In this paper, a new topology aggregation algorithm called SA approach is presented for hierarchical networks with delay and bandwidth constraints. This approach uses an approximation staircase generated by a line segment to represent the QoS supported area for the purpose of representing the parameters of a logical link in the full-mesh; furthermore, the spanning tree and star topology are employed to compress the full-mesh. Experimental results show that the new topology aggregation method can reduce more information distortion and achieve a better tradeoff between information reduction and accuracy than existing approaches.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114758801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming at adding semantic description to Web services, and solving problems of similarity calculations in Web services semantic annotation, an improved annotation method was developed: using similarities between WSDL and ontology to annotate services. The method improves similarity algorithms from two aspects: on one hand, the most-related concepts are filtered out according to name similarities between concepts so as to reduce the computational work; on the other, setting different weights to different sub-concepts to raise the accuracy of the structural similarity algorithm.
