The changes of process model may result in process instances migrating to the modified process model, which is prone to introduce executing conflicts in the migrated process instances. It is difficult to determine the migrating condition of different process instances due to multi-paths existing in the process model. In this paper, on the one hand an efficient approach based on a novel correctness criterion for process evolution is proposed, which can determine the migrating strategies of process instances with diverse of routing structures and running states automatically, and ensure the most migrated process instances executing correctly without rollback tasks in them. It is based on the concept of point of change, and an algorism to find out these points is developed. On the other hand, the problem of how to migrate a process instance among many variants of process schemas is discussed. The algorism of process evolution based on the correctness criterion is also developed. The results in this paper are suitable for realizing an adaptable process middleware.","PeriodicalId":174433,"journal":{"name":"2012 International Conference on Communication Systems and Network Technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125973206","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}

Unfortunately heavy computation cost and key management limit the employment of the first approach and the poor quality of the recovered image from the random shares limit the applications of the second approach. In this paper we propose a novel approach without the use of encryption keys. The approach employs Sieving, Division and Shuffling to generate random shares such that with minimal computation, the original secret image can be recovered from the random shares without any loss of image quality.","PeriodicalId":174433,"journal":{"name":"2012 International Conference on Communication Systems and Network Technologies","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121830336","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}

Most of the content on the web is in the form of unstructured text which can be structured using Information Extraction techniques. In this paper we have discussed marketing potential of social networking sites in Agro-produce marketing domain. The farmers can post about their produce information on social networking site like twitter. The merchants can show their interest for any product by posting a tweet. These tweets can be analyzed and suggestions can be generated for both farmers and merchants. A domain specific information extraction system is developed for Agro-produce marketing domain for extracting entities crop name, variety, price, quantity, location and deadline from the web. The text engineering framework - General Architecture for Text Engineering (GATE) provides ANNIE, an information extraction plug-in, which is extended and modified for building the system. The core of the system is based on pattern action grammar rules.","PeriodicalId":174433,"journal":{"name":"2012 International Conference on Communication Systems and Network Technologies","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133876366","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 the fields of academic publishing too, it has had its great influence. With the advent of the client-server based models of computing and the World Wide Web, the whole process merely reduces to typing out the document on the computer, a series of mouse clicks and receiving information via email. Not only does this save the cost of paper publications, it also saves the valuable time of both the publishers and the authors. By making the actual publication process quite convenient, easy and accessible, it helps in shifting the focus of the publishers more onto the quality and content of the journals themselves. Numerous publishing companies have either developed or acquired such IT systems for these tasks, notably [26, 27]. This paper makes a systematic case study of the general functions that such a system has to demonstrate, with SXC-IJACS as an example. A paper on the more technical aspects of the work [Bhattacharyya et. al., 2012] has been previously published at an international conference [19, 29].","PeriodicalId":174433,"journal":{"name":"2012 International Conference on Communication Systems and Network Technologies","volume":"357 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133070248","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}

For more than two transmit antenna systems, Quasi Orthogonal STBC (QOSTBC) and Constellation Rotation QOSTBC (CR-QOSTBC) is found to be appropriate. Various proposed STBC schemes are evaluated over Rayleigh fading channels, where there is no consideration for correlation between antennas. Inadequate distance between antennas creates correlated channels. Over this channel the performance of various schemes must be evaluated. This paper shows that the performance of various STBC systems is influenced by correlated channel. We analyze the performance of QOSTBC and CRQOSTBC systems over correlated wideband channels. The effect of correlation over CRQOSTBC and QOSTBC systems is presented by varying antenna spacing parameter in kronecker channel model. The comparison between CRQOSTBC and QOSTBC over correlated and uncorrelated channels is also discussed in this paper on the basis of simulations.","PeriodicalId":174433,"journal":{"name":"2012 International Conference on Communication Systems and Network Technologies","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130139298","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}
