To satisfy the requirement of VSCF, the electromagnetic field was coupled with the outside circuit in FEM calculation, and the stator terminal voltage was taken as the convergence condition. Rotor exciting current was iterating calculated, and the performance of double-fed wind generators at different speed and different load was analyzed. Then the obtained results were compared with the experimental data, from which it could be seen that the calculated results satisfy the engineering requirements well.

An improper position will lead algorithm to fail. To enhance the accuracy of feature detection, a Quick Rough Positioning Model(QRPM) algorithm is proposed, which makes use of the image and model gray information to calculate the similar coefficient between the model and the region detected. Coarse and fine explorations are adopted to extract the rough region, where the initial model will be set.

However, current P2P applications use dynamic port numbers, HTTP masquerading and inaccessible payload to prevent being identified. The paper proposed an accurate P2P identification system using Decision Tree algorithms (J48 and REPTree) on the basis of effective feature selection. The experimental results show that our scheme is of better accuracy, less computational complexity and it is robust enough to deal with the unknown P2P traffic. With the merits, the scheme can suit the real-time active detection environment, such as monitoring network attacks camouflaged with P2P traffic and service differentiation.","PeriodicalId":127238,"journal":{"name":"2007 International Conference on Computational Intelligence and Security (CIS 2007)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124752320","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}

Barak et al. and Groth et al. answered this question affirmatively under the assumption of the existence of Hitting Set Generators against co-nondeterministic circuits and Decisional Linear Assumption, respectively. In this paper, we will construct ef- ficient non-interactive Zaps under the existence of one-way function. In 2006, Chase and Lysyanskaya defined and con- structed signatures of knowledge based on non-interactive zero-knowledge proof. We prove that their signature is not secure and point out that they exist under the existence of trapdoor permutation. Feige and Shamir stated that digi- tal signature cannot be zero-knowledge(otherwise they are forgeable) and it can be witness hiding. In this paper, we will revise the definition of the signatures of knowledge by using witness hiding protocol and construct them under the existence of one-way function.","PeriodicalId":127238,"journal":{"name":"2007 International Conference on Computational Intelligence and Security (CIS 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129827644","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}

On the other hand, the new framework models observations via a conditional random field (CRF), which incorporates the contextual information in observed data. The new MRF framework with the dual adaptive contextual information offers several advantages over the conventional framework.
