Particularly, it allows the effectiveness of a set of test data to be evaluated in terms of the ability to reveal faults. Nowadays, many industrial complex systems are more and more developed. Such systems require more testing activities to ensure a good quality. Simulink is one of the most popular tools to develop this kind of systems. In this paper, we focus on studying the application of mutation testing technique to Simulink models. We propose a set of mutation operators by basing on investigating common faults in Simulink models. A process of mutation testing for Simulink models is also presented. Some first experimentations show the promising outcomes.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132602211","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}

In SOA, new services can be developed by using existing services. BPEL is considered as the main means for composing services. In service composition, a composite service may be built from element services which belong to different administrative domains. Therefore, in order to exploit the benefits of service composition, we must carefully consider security issues. One of them is to protect users' information. In this paper, we describe an approach for securing BPEL composite Web services. We assume that some users' data received by the composite services needs securing. The proposed approach makes sure that when the data is sent out from the composite service appropriate security policies will be applied.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128296144","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}

In this paper, we introduce an approach of decoding in SMT using less memory but translating faster, which is more suitable for mobile applications and embedded systems. In our approach, the SMT models are stored in tree structures in order to speed up the loading process and the decoding algorithm is optimized to reduce operations. We apply our approach to English-Vietnamese and Vietnamese-English SMT systems. When translating 20,000 English sentences, which are 7.45 word lengths in average, we achieve 37.8 BLEU score, the average speed is 0.052 s.

We chose SoaML introduced by OMG as a standard UML profile for modelling services, and CASL4SOA, a formal visual notation for service oriented systems based on CASL that resulted from a unification effort of the algebraic specification community. We illustrate both approaches using a case study.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130606835","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}

Through this approach, semantics is quantified by semantics quantitative mapping of hedge algebra in such a way that still preserves semantic order and may allow to manipulate the data on the real domain of attribute in relation to the linguistic semantics. On such a basis, evaluating semantics, searching uncertain and fuzzy information, and classical data entirely comes to a consistence based on ensuring data homogeneity. Hence, we construct the algorithm that carries out a data matching in service of data query.

Genetic Programming was used to evolve the function that ranks the sentences in a document based on their importance. The summary was extracted by selecting the sentences that have the highest rankings. The experiment was conducted on a number of Vietnamese news documents. The result showed that the summaries created by Genetic Programming are better than those created by a number of statistic based methods and even by human (non-experts).","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116667384","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}

In detail, we will experimentally show that taking up the lexical translation seems to be an appropriate approach to force \"higher\" word-based translation models be able to efficiently \"boost\" their merits.

Discovering time series motifs is a crucial task in time series data mining. Among a dozen algorithms have been proposed for discovering time series motifs, the most popular algorithm is Random Projection. This algorithm can find motifs in linear time. However, it still has some drawbacks. In this paper, we propose a novel method for discovering approximate motifs in time series. This method is based on MP_C dimensionality reduction method with the support of Skyline Index. Our method is disk-efficient because it only needs a single scan over the entire time series database.
