This paper proposes a comparatively simple technique on the parallel implement of Multi-objective Particle Swarm Optimization algorithm (MOPSO). The transformation of the sequential objective evaluation in the MOPSO is based on the Matlab parallel computing tool box. Two study cases of different complexity demonstrate that the parallel implementation resulted in a considerable time saving. The deviation of computational time indicates that MOPSO has the characteristic of randomness because of the crowding distance and the dominant ranking. The proposed parallel MOPSO therefore, provides an ideal means to solve global optimization problems that are comparatively with high complexity.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"02 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116777163","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}

The system fully takes advantage of the scientific workflow technique and support many useful features such as data provenance, workflow re-run mechanism and batch data presentation. The system overcomes the drawbacks of data dissemination system. A series of advantages for scientific data process such as the user can design and upload components to customize specific query tasks are discussed.

This device is designed specially for the shopping activities because it is based on shopping processes. Different shopping steps need different ubiquitous computing. The device is aimed to include every necessary functions consumer need. For before-shopping step, what and where to buy will be solved with corresponding functions.

Therefore, the security of network transmission in this model has become an increasingly important issue. In view of the low security of traditional DES algorithm and slow RSA encryption speed, this paper presented an Encryption Algorithms model of data packets on the basis of analyzing the methods of existing network transmission. The algorithm model realizes a simple Authentication Center which simulates Kerberos authentication service. Through improving Kerberos protocol, strengthening the secure of the authentication process and defending the attack of replay effectively, security Transmission by Network of C/S model is realized. The result of experimentation shows that the proposed algorithm has the advantages of fast encryption (decryption) speed, high efficiency, strong safety.
