At the same time, these problems decrease the recommender accuracy and influence the application effect of the recommender systems. Aiming at these problems, this paper presents a collaborative filtering algorithm based on adaptive artificial immune network. In the algorithm, the clone and mutation mechanism of the artificial immune network is utilized to get the implicit ratings to reduce the data sparsity. The algorithm uses the clone suppression and network suppression to decrease the data dimension and improve the scalability of recommender system. The experiment results indicate that the algorithm can improve the recommender accuracy.","PeriodicalId":256032,"journal":{"name":"2009 International Forum on Computer Science-Technology and Applications","volume":"26 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123151635","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}

Firstly, this paper designs the hardware subsystem with three-layer structure. At the information center layer, four data acquiring servers are linked with a double control disk array subsystem, which ensures the stability of monitoring system. The network layer adopts the RS485-TCP/IP mode and the RS485-ZigBee-TCP/IP mode to collect information from RS485 protocol terminal modules. Then this paper introduces the software subsystem with multi-tier distributed application services, which contains the persistence layer, the application layer, and the representation layer. Every layer is independent relatively, and may be developed by different technology. Based on the sufficient energy monitoring data, MSBEC could provide technical support for later energy retrofit.","PeriodicalId":256032,"journal":{"name":"2009 International Forum on Computer Science-Technology and Applications","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124868541","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 overcome this demerit a method of detecting stable and unstable states is introduced and proved. According to the method we experimented with pure DEAPspace to detect the stable and unstable states, and the results prove the correctness of the theory.

As a consortium of national and international institutions, WOCAT (World Overview of Conservation Approaches and Technologies) has developed a database system to record specific details about the environmental and socioeconomic setting in soil and water management. Factor analysis, as a data mining technique, was used in the present work and the results show that adoption of SWC measures were influenced primarily by four factors including economic efficiency, human setting and land use, natural environment and soil quality. The first factor named as economic efficiency explained 18.888% of the total variance which comprised of variables like short term returns to establishment, long term returns to establishment, short term returns to maintenance and long term returns to maintenance. The second factor called human setting and land use explained 17.546% (comprised of variables like land ownership, off-farm income, market orientation, wealth, production subsidy and size of crop land per household) and the third factor called natural environment explained 14.945% (comprised of variables like average annual rainfall and slope) of the total variance, respectively. Furthermore, forth factor called soil quality explained 13.483% of the total variance comprised of soil fertility and topsoil.","PeriodicalId":256032,"journal":{"name":"2009 International Forum on Computer Science-Technology and Applications","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114260925","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}
